Description

{DOCUMENT SEARCH METHOD FOR PROVIDING SIMILAR INFORMATION OF SIMILAR DOCUMENTS}

The present invention relates to a literature search method for providing similar information on similar documents.

Existing patent search platforms have the function of providing similar prior literature based on keywords or search conditions entered by the user. However, when the amount of similar prior literature provided by the patent search platform is very large, the user is burdened with having to select the literature he or she wants from a large number of documents. There are also frequent cases where the documents provided do not match the user's search intent, which reduces the reliability of the search results. As a result, the user has to spend a lot of time and effort to reach the information he or she is looking for.

In order to help users efficiently find the information they need, more sophisticated search algorithms and user-friendly filtering functions are essential. It is necessary to strengthen the function of evaluating and classifying the relevance of prior literature so that users can easily find relevant literature. In addition, an improvement in the interface that provides search results more intuitively and clearly is also required.

The present invention aims to provide a literature search method that shows similar information about similar documents through a user-friendly interface.

The literature search method of the present invention may include a step of searching for similar documents based on at least one phrase input by a user, a step of listing the searched similar documents, and a step of listing, from the searched similar documents, cards including at least one phrase or at least one similar phrase having a similar meaning to the at least one phrase.

The literature search method of the present invention can provide search results to the user through a user-friendly interface. The present invention can collect and list sentences or paragraphs containing phrases input by the user among similar documents. The user can easily find similar documents desired by the user using the listed sentences or paragraphs.

In describing the present invention, in order to facilitate an overall understanding, the same reference numerals are used for the same components in the drawings, and redundant descriptions of the same components are omitted.

The literature search method of the present invention can provide search results to the user through a user-friendly interface. The present invention can collect and list sentences or paragraphs that contain phrases that the user is looking for among similar documents. The user can easily find similar documents that the user wants by using the listed sentences or paragraphs.

Hereinafter, the attached drawings illustrate user interface screens shown to a user through the literature search method of the present invention. Hereinafter, for convenience of explanation, the literature search method of the present invention is expressed as providing the screens illustrated in the drawings, but the present invention is not limited thereto. Providing a screen by the literature search method of the present invention may mean generating data for providing the screens illustrated in the drawings and transmitting the generated data to a user's device. In addition, in the descriptions below, a 'user' may be a person who searches for similar documents similar to the target invention through the literature search method of the present invention.

FIG. 1 is a drawing showing a search screen according to an embodiment of the present invention.

The literature search method may provide a screen for receiving information on the target invention from the user. The literature search method may receive information on the target invention in various ways (e.g., searching by sentence, searching by patent number, searching by image, uploading a document disclosing the invention). When the user selects a search by sentence, the literature search method may display configuration input fields (111, 112) for receiving information on the target invention. The user may input information in the form of phrases into the configuration input fields (111, 112), respectively. The phrases input into the configuration input areas (111, 112) may each correspond to the configurations of the target invention. That is, the phrases input by the user may correspond one-to-one with the configurations of the target invention, respectively. In the following descriptions, a phrase means that it is composed of one or more words. For example, a phrase may be in the form of a sentence in which multiple words are listed, multiple words may be combined by operators (e.g., and, or, not, etc.), or one or more words may be listed.

The literature search method may display search conditions (113) for searching for documents. In Fig. 1, the literature search method is illustrated as displaying the country from which the documents were received and the type of the documents, but the present invention is not limited thereto. According to another embodiment of the present invention, the literature search method may not display search conditions (113), or the search conditions (113) may be configured to include various items not disclosed in the drawing.

When the user has completed entering information on the target invention and/or setting search conditions, the user can press the search button (114) at the bottom of the screen. The literature search method can search for similar documents similar to the target invention when the user's input is obtained by clicking the search button (114). The name of the button is not limited thereto.

Similar documents similar to the target invention may be determined as being similar to the target invention among the candidate documents based on the document similarity between the target invention and the candidate documents. The document similarity may be corrected by the phrase similarity statistics of the corresponding documents. For example, the phrase similarity statistics of the first candidate document may be calculated using the phrase similarity statistics for the first configuration, the phrase similarity statistics for the second configuration, the phrase similarity statistics for the k-th configuration (k is an integer greater than or equal to 1), and the composition-specific weights. The phrase similarity statistics for the k-th configuration may be any one of the highest value, the average value, the lowest value, or the median value of the similarity(s) between the first similar phrase to the n-th similar phrase corresponding to the k-th configuration in one candidate document, or the n value (n is an integer greater than or equal to 1) which is the frequency of appearance of similar phrases, but is not limited thereto. The composition-specific weights may be set by a user or an administrator. Alternatively, they may be inversely proportional to the composition-specific similarity statistics for the entire document. For example, since a universal configuration has a high statistical value of similarity to that configuration, a low weight can be applied to that similarity. FIGS. 2A and 2B are diagrams showing search screens according to other embodiments of the present invention.

The literature search method may provide a screen for receiving information about the target invention from the user. The literature search method may use a method for receiving information about a patent document as well as the method described with reference to FIG. 1 (for example, a method for searching by sentence). The user may select a search by sentence or a search by patent number to input information about the target invention. If the user selects a search by patent number, the literature search method may provide the user with a screen (120). The screen (120) may display a patent search area (121). The user may input information about a patent document that discloses the target invention into the patent search area (121). In FIGS. 2A and 2B, the literature search method is illustrated as displaying a country, a number type, and a number in the patent search area (121), but the present invention is not limited thereto. The literature search method may provide a patent search area (121) so that the user may input information about the patent document in various ways. After inputting information about the patent document, the user may click a load button.

The name of the button is not limited thereto, but when the user clicks the load button, the literature search method may provide a screen (130). The screen (130) may provide a patent search area (131), a content area (132) showing the content of the patent document searched by the user, and a claims area (133) showing the claims of the patent document searched by the user. In FIGS. 2A and 2B, the content area (132) is illustrated as displaying drawings, bibliographic information, and summaries of the patent document searched by the user, but the present invention is not limited thereto. The claims area (133) may display claims selected by the user from among claims of the patent document searched by the user. The user may select any claim desired by the user from among claims of the patent document by clicking Select Other Claim in the claims area (133). When the user selects a claim that cites another claim, information on the cited claim (cited claim) may also be considered to be selected.

The literature search method can recognize the claims selected by the user as the target invention. The literature search method can divide the claims selected by the user into multiple phrases. Each of the multiple phrases constituting the claims can correspond to the components of the target invention. That is, when the information on the target invention input by the user is information on a patent document, the components of the target invention can be expressed by one of the claims of the patent document or modified by the user. This content is described in detail with reference to FIG. 3.

When the user has completed entering information about the patent document, he or she can press the search button. The document search method can search for similar documents similar to the target invention when the input of the user who clicked the search button is obtained.

Figure 3 is a conceptual diagram showing the relationship between a user-selected claim and the target invention. For convenience of explanation, Figures 2a and 2b are referred to together.

As described with reference to FIGS. 2A and 2B, when the information on the target invention input by the user is information on a patent document, the literature search method can recognize the claim selected by the user as the target invention. The literature search method can divide the claim selected by the user into a plurality of phrases (a0, b0, ..., n0). The plurality of phrases (a0, b0, ..., n0) may each correspond to components of the target invention. That is, the plurality of phrases (a0, b0, ..., n0) constituting the selected claim may each correspond one-to-one with components of the target invention. The plurality of phrases (a0, b0, ..., n0) may include one or more sub-phrases. The sub-phrases may have the same structure as the phrases described in this specification. A phrase means that it is composed of one or more words. For example, a phrase may be in the form of a sentence in which a plurality of words are listed, a plurality of words may be joined by operators (for example, and, or, not, etc.), or a form in which one or more words are listed.

FIG. 4 is a drawing showing a search result screen according to one embodiment of the present invention.

The literature search method may provide a search result screen (200) showing search results for similar documents similar to the target invention. The search result screen (200) may include a literature area (210), a matching area (220), and a phrase area (230). However, the present invention is not limited thereto, and may not include some of the areas (210 to 230) shown in the search result screen (200), and may additionally include unshown areas.

The literature search method can display a list of similar documents in the literature area (210), the similarity between the target invention and similar documents, and the similarity between the components of the target invention and the phrases included in the similar documents. The similarity can indicate the highest value, average value, lowest value, or median value among the similarity between each component and each phrase, or can mean the frequency of appearance of similar phrases.

The literature search method can search for similar documents describing similar inventions similar to the target invention in a database. The literature search method can designate documents determined to be similar to the target invention among the candidate documents based on the document similarity between the target invention and candidate documents stored in the database as similar documents. The similar documents may be documents whose document similarity with the target invention is higher than a threshold document similarity. For example, the threshold document similarity may be a value pre-specified by a user or an administrator. As another example, the threshold document similarity may be an average value of the similarity between the candidate documents and the target invention. In this specification, the similarity between the target invention and the candidate documents may mean the similarity between the target document and the candidate documents. The target document may be in the form of a document generated based on phrases entered by a user or a patent document entered by a user.

The document similarity between the target invention and the candidate document can be calculated based on at least one of the average value of phrase similarity of at least one phrase included in the candidate document, the maximum value of the phrase similarity, the maximum value of the frequency of the at least one phrase, the average value of the frequency, and the minimum value of the frequency.

The literature search method can generate a similar literature list about similar literature. The similar literature list can include information about similar literature. For example, the information about similar literature can include document numbers (such as application numbers, announcement numbers, registration numbers, etc.), document dates (such as application dates, publication dates, registration dates, etc.), and information about the applicant.

The literature search method can generate literature similarity information between similar literature and the target invention. The literature search method can display literature similarity information between the similar literature and the target invention adjacent to the similar literature list on the search result screen (200).

In addition, the literature search method can generate phrase similarity information between passages of similar documents and components of the target invention. The literature search method can display information about the similarity between similar passages included in the similar documents and components of the target invention adjacent to the similar document list on the search result screen (200). The phrase similarity information can be corrected based on the document similarity value between the target invention and the candidate documents. A similar passage can be a passage whose phrase similarity between the components of the target invention and the components of the similar documents is greater than or equal to a threshold phrase similarity. In the following descriptions, the k-th similar passages can be passages whose phrase similarity with the k-th component is greater than or equal to a threshold phrase similarity among passages of similar documents. The n-k-th similar passage can be a passage whose phrase similarity with the k-th component is greater than or equal to a threshold phrase similarity among passages of the n-th similar document. n and k are natural numbers. The threshold phrase similarity can be a value pre-specified by a user or an administrator. In addition, the threshold phrase similarity can be an average value of the similarity between passages included in the similar documents and components of the target invention.

The literature search method can generate k-th phrase similarity information and/or n-k-th phrase similarity information. The k-th phrase similarity information and the n-k-th phrase similarity information mean similarity information about the k-th similar phrase and the n-k-th similar phrase, respectively. For example, the n-k-th phrase similarity information may be the highest value among the similarities of the n-k-th similar phrases, the number of n-k-th phrases, etc. As an example, 'a11' shown in FIG. 4 corresponds to the 1-1 phrase similarity information. As a specific example, 'a11' may be an integer between 1 and 99, which may be represented as a numerical value expressing similarity. The phrase similarity information may be displayed adjacent to the labeling information. The labeling information is information about the relationship between phrases or similar phrases included in a composition and a similar document. The labeling information may be manually specified by a user, for example, or may be automatically specified by inference of an algorithm or an artificial intelligence model. The labeling information may have a continuous value or a discrete value. As an example of a discrete value, it can have at least one of the following values: similar, related, dissimilar, and unspecified.

A literature search method may include a step of searching for similar documents based on a first to m-th phrase in the form of a sentence listing a plurality of words input by a user (wherein m is an integer greater than or equal to 1), and an n-th to k-th phrase in the form of a word or a plurality of words combined by an operator (wherein n and k are integers greater than or equal to 1). In this case, the searched similar document may be a document that includes the n-th to k-th phrases while including the first similar phrases to the m-th similar phrases having similar meanings to the first to m-th phrases, respectively. For example, among documents including the first similar phrases to the m-th similar phrases having similar meanings to the first to m-th phrases input by the user, a document that includes the n-th to k-th phrases as they are may be provided.

The literature search method can display information about similar phrases included in similar literature selected by the user in the phrase area (230). The user can select one of the similar literature displayed in the literature area (210). In the initial screen of the search results, information about similar phrases included in the first similar literature can be displayed. The first similar literature means the similar literature displayed first in the literature area (210).

FIG. 4 shows the initial screen of the search results or the search result screen (200) when the first similar document is selected by the user. Referring to FIG. 4, the phrase area (230) displays information about similar phrases 1-1, 1-2, ... , 1-m, ... , k-1, k-2, ... , k-m. k is the number of components included in the target invention. For convenience of explanation, m is assumed to be 2. The document search method can list similar phrases included in the first similar document in the phrase area (230) by dividing them into corresponding components. That is, the document search method can list similar phrases 1-1 consecutively and then list similar phrases 1-2 consecutively.

The literature search method can display similar selection items adjacent to the similar phrases displayed in the phrase area (230) so that the user can finally select whether the similar phrases are similar or not. The similar selection items can be composed of similar, related, and dissimilar. The user can select one of the similar selection items to select the final similarity of the card. This is described in detail with reference to FIG. 11.

The user can select one of the similar phrases displayed in the phrase area (230). The literature search method can display a portion of the similar document that discloses the selected similar phrase in the matching area (220). The literature search method can display not only the similar phrase but also the content before and after the portion containing the similar phrase in the similar document in the matching area (220). When the user clicks or hovers the mouse over the selected similar phrase once more, the literature search method can display the next portion of the similar document containing the similar phrase in the matching area (220). The literature search method can search the entire similar document (bibliographic information, detailed description, claims, drawings) for a portion containing a similar phrase.

The document area (210), the matching area (220), and the phrase area (230) may be listed in the first direction. The subgroups included in each of the document area (210) and the phrase area (230) may be listed in the second direction. The subgroups of the document area (210) may be information about each of the similar documents. The subgroups of the phrase area (230) may be similar phrases divided by similar configuration. The first direction and the second direction may be perpendicular to each other. For example, when the first direction is a horizontal direction, the second direction may be a vertical direction.

FIG. 5 is a drawing showing a search result screen according to another embodiment of the present invention. For convenience of explanation, FIG. 4 is also referred to.

FIG. 5 illustrates a search result screen (200a) when the second similar literature information is selected by the user in the literature area (210) illustrated in FIG. 4. Referring to FIG. 5, the phrase area (230a) displays information about the 2-1 and 2-2 similar phrases. The literature area (210a), the matching area (220a), and the phrase area (230a) are substantially the same as the literature area (210), the matching area (220), and the phrase area (230), so any redundant description will be omitted below.

FIG. 6 is a drawing for explaining a screen showing similar documents and cards according to one embodiment of the present invention.

A card mode screen (300) such as FIG. 6 includes areas. The card mode screen (300) includes three areas, but the present invention is not limited thereto. The areas may be arranged in a first direction. Each area may include one or more sub-areas. One or more sub-areas may be arranged in the first direction within each area. Lists (specifically, cards) displayed in each sub-area may be listed in a second direction. The first direction and the second direction may be perpendicular to each other.

Each of the areas can display one of a similar literature list, similar literature information, and the first to fourth type layout screens. The sub-areas can display the content displayed in the areas more specifically. For example, each of the sub-areas of the area displaying similar literature information can display one of bibliographic information, detailed description, claims, and drawings of the similar literature. Specifically, the sub-area displaying bibliographic information can display at least one of a legal status of the relevant document (e.g., publication, registration, etc.), document type, application number, application date, publication number, publication date, international publication number, international publication date, priority information, highest priority date, applicant, inventor, current right holder, abstract, and technical classification (e.g., IPC, CPC, etc.). The sub-area displaying claims can display only independent claims or both independent and dependent claims, depending on the user's selection.

FIG. 7 is a drawing showing a first type arrangement screen according to an embodiment of the present invention. For convenience of explanation, FIG. 6 is also referred to.

The first type layout screen (301) is used to display a card corresponding to one configuration for one selected similar document. When the area shown in Fig. 6 represents the first type layout screen, each of the sub-areas included in the area can display a card corresponding to a different configuration for one selected similar document.

The card mode screen (300) may be composed of various combinations of similar literature information and the first type layout screen (301). For example, the first area may display information about a selected similar literature, and the second area may display a first type layout screen for the selected similar literature. In this case, each sub-area included in the first area may display one of bibliographic information, detailed description, claims, and drawings for the selected similar literature, and each sub-area included in the second area may display a card corresponding to a different configuration for the selected similar literature. As another example, each of the plurality of areas may display a first type layout screen (301) for a different similar literature.

When searching for similar documents, one or more phrases corresponding to each of one or more configurations may be entered. The first type arrangement screen (301) may display first cards (164a, 164b, 164c) including one or more first phrases corresponding to one configuration or one or more first similar phrases similar to one or more first phrases among the selected similar documents. The first cards (164a, 164b, 164c) may be listed in a second direction perpendicular to the first direction. The plurality of cards (164a, 164b, 164c) may be listed according to the degree of similarity with the first phrase.

Here, a card means a part of a similar document including at least one phrase input by a user or similar phrases having a similar meaning to at least one phrase. Referring to FIG. 3, a document search method can divide a claim selected by a user into a plurality of phrases (a0, b0, ..., n0). The plurality of phrases (a0, b0, ..., n0) may each correspond to components of a target invention. The document search method can select one or more phrases corresponding to one component among one or more phrases input by the user. The document search method can display cards including the selected phrase and similar phrases similar to the selected phrase. A similar phrase may be a phrase that has a different form but the same meaning as at least one phrase input by the user, a phrase with an omitted or added particle, or a phrase with the same root through natural language processing.

Referring to FIG. 7, the first type layout screen (301) includes a selection phrase area (161), a search window (162), literature information (163), and a plurality of cards (164a, 164b, 164c). The selection phrase area (161) can display a phrase corresponding to a configuration selected by a user among phrases entered when searching for similar literature. The search window (162) is an area for entering a phrase to be searched for among a plurality of cards (164a, 164b, 164c). The user can enter a phrase through the search window (162). In this case, cards including the phrase entered through the search window (162) can be displayed.

The literature information area (163) is an area for displaying information on selected similar literature. The literature search method can display brief information (for example, at least one of the title of the invention, application number, publication number, and registration number) on the similar literature through the literature information area (163).

At this time, according to the user's input, the literature search method can set the range from which the card is extracted. For example, the range from which the card is extracted can be one or more of the title, abstract, independent claim, dependent claim, entire claim, and description of the invention, or a combination thereof. The range from which the card is extracted can be set differently for each phrase. The set range can be displayed together with the selected phrase in the selection phrase area (161).

FIG. 8 is a drawing showing a second type layout screen according to an embodiment of the present invention.

The second type layout screen (302) is used to display cards corresponding to multiple configurations for a selected similar document. The card mode screen (300) can be configured with various combinations of similar document information, the first type layout screen (301), and the second type layout screen (302). For example, a first area can display information for a selected similar document, a second area can display a first type layout screen (301) for the selected similar document, and a third area can display a second type layout screen (302) for the selected similar document. In this case, the second area can display cards for the remaining configurations that are not displayed in the first area. As another example, when only the second type layout screen (302) appears on the card mode screen (300) without the first type layout screen (301), the second type layout screen (302) can display cards for all configurations.

The second type layout screen (302) can display configuration areas (173, 174, 175) each corresponding to a plurality of configurations. The configuration areas (173, 174, 175) can be listed in the second direction. Each of the configuration areas (173, 174, 175) can display one or more cards from a group of cards including one or more phrases corresponding to the corresponding configuration and similar phrases similar to the one or more phrases.

The configuration area (173) includes a selection phrase area (173a), a card (173b), and a page cursor (173). The configuration area (173) may be an area for displaying cards included in a first card group corresponding to the first configuration. The configuration area (173) may display a card (173b) corresponding to the first configuration. The selection phrase area (173a) and the card (173b) are substantially the same as the selection phrase area (161) and the card (164a) described with reference to FIG. 7. The second type layout screen (302) may display another card included in the first card group instead of the card (173b) depending on a user's operation (e.g., selecting a page cursor (173c), touching the screen, scrolling, etc.). That is, a card displayed in the configuration area (173) may be replaced with another card depending on a user's operation. The number of cards displayed simultaneously in the configuration area (173) is not limited to one, and the configuration area (173) can display more than one card simultaneously. Since the configuration areas (173, 174, 175) have substantially the same configuration, a description of the remaining configuration areas (174, 175) is omitted.

FIG. 9 is a drawing showing a third type layout screen according to an embodiment of the present invention.

The third type layout screen (303) is used to display cards corresponding to one configuration for multiple similar documents. When the area shown in Fig. 6 represents the third type layout screen (303), each sub-area included in the area can display cards corresponding to different configurations for multiple similar documents.

The literature area (183) can display a literature information area (183a) and a card (183b). Since the literature areas (183, 184, 185) have substantially the same configuration, a description of the remaining literature areas (184, 185) is omitted.

FIG. 10 is a drawing showing a fourth type arrangement screen according to an embodiment of the present invention.

The fourth type layout screen (304) is used to display cards corresponding to multiple configurations for multiple similar documents. The fourth type layout screen (304) can display configuration areas (192, 193, 194) each corresponding to multiple configurations. The configuration areas (192, 193, 194) can be listed in the second direction. Each of the configuration areas (192, 193, 194) can display one or more cards from among a card group including one or more phrases corresponding to a corresponding configuration for multiple similar documents and similar phrases similar to the one or more phrases.

The configuration area (192) includes a selection phrase area (192a), a card (192b), and a page cursor (192c). In this case, the card (192b) may also display information about a similar document including the card. The configuration area (192) may be an area for displaying cards included in a first card group corresponding to the first configuration. The configuration area (192) may display a card (192b) corresponding to the first configuration. The cards displayed in the configuration area (192) may not be cards included in one similar document, but may be cards included in a plurality of similar documents. The fourth type arrangement screen (304) may display another card included in the first card group instead of the card (192b) depending on a user's operation (e.g., selecting a page cursor (192c), touching the screen, scrolling, etc.). That is, depending on a user's operation, a card displayed in the configuration area (192) may be replaced with another card. The number of cards displayed simultaneously in the configuration area (192) is not limited to one, and the configuration area (192) can display more than one card simultaneously. Since the configuration areas (192, 193, 194) have substantially the same configuration, a description of the remaining configuration areas (193, 194) is omitted.

Similar to what was described with reference to FIG. 9, the card mode screen (300) may be composed of various combinations of a similar literature list, similar literature information, a first type arrangement screen (301), a second type arrangement screen (302), a third type arrangement screen (303), and a fourth type arrangement screen (304).

For example, when the first area represents the fourth type arrangement screen (304), the second area may represent the first type arrangement screen (302). In this case, the first area may display a card corresponding to one configuration for the entire similar literature. When the first area includes a plurality of sub-areas, each of the sub-areas may display a card corresponding to a different configuration. The second area may display a card corresponding to one configuration for a similar literature selected from the entire similar literature. As another example, when the first area represents the fourth type arrangement screen (303), the second area may display a list of similar literature. In addition, the first area may represent the fourth type arrangement screen (304), and the remaining areas may be configured with combinations described with reference to FIGS. 6 to 9.

In the areas and sub-areas described with reference to FIGS. 6 to 10, similar documents and cards may be listed in order of similarity with the target invention and the target phrase. Similar documents may be listed basically in order of similarity with the searched invention. When a user selects a specific configuration, similar documents and/or cards may be listed in order of similarity with the phrase corresponding to the configuration. The similarity of the cards may indicate the highest, average, lowest, or median value among the similarity between the configuration and each phrase for each configuration, or may mean the frequency of appearance of similar phrases. The similarity of the similar documents may be determined as a value that reflects the weight of the statistical value of the similarity of the cards included in each similar document (for example, the highest, average, lowest, or median value). In this case, different weights may be applied to the similarity of the cards corresponding to each configuration for each configuration. The weights may be inversely proportional to the statistical value of the similarity for each configuration for the entire document. For example, a universal configuration may have a high statistical similarity to that configuration, so a low weight may be applied to that similarity.

The similar phrase areas by document (420, 430) may include a drawing or image selected by the user, or a sequence list. The similar phrase areas by document (420, 430) may include a phrase designated by the user as similar to a target phrase or a text directly entered. Information that can identify the user who selected, designated, or entered may be included together. In addition, when the user selects report generation, a report (e.g., a document, a table, a drawing) in which the configuration area (410) and similar phrase areas by document (420, 430) are arranged may be generated, as illustrated in FIG. 9.

At this time, the similar phrase areas (420, 430) by document may be displayed so as to be distinguished by corresponding configurations (for example, configuration 1, configuration 2, etc. included in the configuration area (410). Specifically, each of the similar phrase areas (420, 430) by document may display at least one card corresponding to configuration 1 and at least one card corresponding to configuration 2 so as to be distinguished from each other. That is, the similar phrase areas (420, 430) by document corresponding to configuration 1 may be listed in the same row, and may be listed in a different row from the similar phrase areas (420, 430) by document corresponding to configuration 2. In addition, the first cards included in the similar phrase area (420) may be listed in the same column, and may be listed in a different column from the second cards included in the similar phrase area (430).

The configuration area (410) and the literature-specific similar phrase areas (420, 430) may be listed in a first direction. The subgroups included in each of the configuration area (410) and the literature-specific similar phrase areas (420, 430) may be listed in a second direction. The first direction and the second direction may be perpendicular to each other. For example, when the first direction is a horizontal direction, the second direction may be a vertical direction.
