Description

  The present invention relates to a method, a server, and a program for transmitting item data. In particular, the present invention relates to a method, a server, and a program for transmitting item data to a terminal connected to a communication network.

  With the spread of the Internet to the society, not only passive users who browse information on the network, search, or purchase products, but also users themselves as information senders on the Web The number of users who take active actions such as publishing a simple diary (so-called blog) or forming a community with people with similar preferences is rapidly increasing.

  In particular, the background of the rapid spread of blogs over the past few years is thought to be largely due to the contribution made by blog editors, which even beginners of the Internet can easily register and send texts and photos on their homepages.

  And the spread of such blogs to society is another one in which the society on the network (so-called network community) that was not considered in the era when the information was browsed simply by the terminal that can be connected to the communication network is different from the actual society. It has emerged and shows that it is developing rapidly.

  Under such circumstances, an increasing number of users utilize “avatars” as symbols representing the users themselves on the network. An avatar that means “another” is a so-called character that is specifically represented by image data, video data, audio data, etc., but expresses itself in a network community that exists separately from the real society, In various activities such as interacting with, sympathizing with and discussing with other users, and expanding friendships that are similar to each other, it has increased its significance as a pseudo-acting subject.

  Specifically, for example, when publishing a blog, by using an avatar in the screen, the user can be intuitively expressed by character data separately from the document written by the user. Viewers can feel as if their alternation exists on the network, and can strongly support communication in the network community.

  In fact, coordinating items such as the avatar's hairstyle, clothes, accessories, accessories, and backgrounds is one of the important activities in the network community to appeal to users' senses and preferences. For this reason, the user purchases such an item for a fee or presents it to a friend, and the coordination of the avatar is also an object of economic activity.

  Therefore, as with buying clothes in the real world and coordinating accessories and accessories, avatar coordination activities determine user preferences on the network and capture trends and changes in the network community. It is also an important analysis target.

  In such a situation, the user usually selects a favorite avatar by freely selecting from items prepared in advance, but an avatar is automatically generated by an avatar management device (server). -A method of updating has also been proposed.

For example, in Patent Document 1, a user's attribute is determined by causing a user to perform a psychological test, a basic image is changed using an accessory (item) image having the determined attribute, and an avatar image is determined. A method of generating is disclosed.
JP 2005-320991 A

  However, even in the above-mentioned Patent Document 1, the conventional technique accepts a user's selection from among prepared options so that an item is selected according to an answer to a predetermined question (psychological test). Is assumed.

  In this way, if a selection input from the user is accepted, the character can be directly reflected on the user's thoughts, but on the other hand, when generating the avatar, the operation by the user is required, which is bothersome. There is a possibility of feeling. In addition, if the avatar is automatically generated, there is a possibility that the user can enjoy the coincidence and difference with the image of the user himself / herself or the unexpectedness.

  Therefore, the present invention automatically obtains user information (for example, user preferences and action content) without receiving an item selection operation by the user to generate a character (avatar), and item data reflecting the user information. It is an object to provide a method for transmitting a message.

  For the above purpose, the following are specifically provided.

(1) A server (server 10) connected to a user terminal (terminal 20) via a communication network (communication network 30) is stored in association with the user ID data of the user (in the avatar DB 201). A method of transmitting item data (image data, video data, audio data, etc.) for constituting a part of data,

The item with a high value is extracted, and the item data of the extracted item is transmitted to the terminal.

  Thus, in response to receiving the document data (Web document such as a blog), the server receives item data (image data or the like) of the item having a high degree of association with the feature data (word) that characterizes the document data. Since it transmits to a terminal, the character (avatar) displayed on the said terminal may reflect the characteristic of the document which the user wrote.

  Therefore, the user can acquire a character image without consciously selecting an item, and can further enjoy the change of the character according to the content of the document.

(2) The method further includes a step of preliminarily storing data indicating a combination of items that can be expressed together in the terminal,
The method according to (1), wherein a predetermined number of items that can be expressed together are extracted based on the degree of association.

  According to such a configuration, the server stores in advance data indicating a combination of items that can be expressed together, and selects a predetermined number of items that can be expressed together based on the degree of association.

  This eliminates the waste of extracting the same type of items that cannot be coexisted and can effectively generate a character.

  (3) According to (1) or (2), when new document data is received from the terminal, item data for replacing one or a plurality of items constituting the character data is transmitted. The method described.

  According to such a configuration, a part of the character data can be changed while utilizing existing character data. As a result, a character can be generated even if the number of extracted items is small, and the user may enjoy a state in which the character changes step by step as the document is written.

  (4) The method according to (1) or (2), wherein when new document data is received from the terminal, item data that replaces all of the items constituting the character data is transmitted.

  According to such a configuration, since the character is generated by selecting all items again, there is a possibility that a character highly related to the contents of the document data can be generated. In addition, there is a possibility that you can enjoy the fun and unexpectedness due to dramatic changes in the character.

  (5) The method according to any one of (1) to (4), wherein in the step of extracting an item having a high degree of relevance, the item is weighted and extracted according to the number of times the item is used. .

  According to such a configuration, there is a possibility that a trend (fashion) including other users can be reflected by weighting according to the number of times the item is used.

(6) further including a step of storing a plurality of synonym data in association with each other;
In the step of extracting an item having a high degree of association, the degree of association of an item including the related synonym data in the item attribute data is highly evaluated. (1) to (5) the method of.

  According to such a configuration, the server stores a plurality of synonym data in association with each other, and highly evaluates the degree of relevance of items including the associated synonym data in the item attribute data.

  As a result, the degree of association between synonyms is highly evaluated, and there is a possibility that items of concept close to the feature data can be extracted effectively. Furthermore, it is possible to reduce variations in the item extraction results between a plurality of feature data including similar words.

An example of a preferred embodiment according to the present invention will be described below based on the drawings.
[System overall configuration]

  FIG. 1 is a block diagram showing an overall configuration of a computer system 1 and a functional configuration of a server 10 according to an example of a preferred embodiment of the present invention.

  Server 10 and terminal 20 are connected via communication network 30. Here, there is no restriction | limiting in the number of the servers 10, You may comprise by 1 or multiple as needed. Further, the server 10 may be configured to include a Web server, a DB server, and an application server as necessary, and may be configured with one server or different servers.

  The server 10 is configured as an avatar management device that manages at least a character as an avatar, and the storage unit 200 includes an avatar DB 201, an item DB 202, a document DB 210, and a synonym dictionary DB 211.

  Furthermore, the control unit 100 controls the entire server 10 and includes at least a morphological analysis unit 111, a feature data extraction unit 112, an item data extraction unit 103, and an item data transmission unit 104.

The server 10 receives a Web document such as a blog created by the user at the terminal 20 and stores it in the document DB 210. Subsequently, the server 10 refers to various data (FIGS. 2, 3, and 6) stored in the storage unit 200, and the control unit 100 extracts item data related to the character (avatar) that is associated with the Web document. 20 to send. Details of the processing will be described later (FIGS. 4 and 5).
[Avatar table]

  FIG. 2 is a diagram illustrating an avatar table according to an example of the preferred embodiment of the present invention.

  The storage unit 200 stores items for each theme such as “face”, “hairstyle”, “clothes”, and “bottoms” in the avatar DB 201, for example, as an avatar table shown in FIG. Item ID data for identifying is stored in association with each other.

  For example, for a user whose user ID data is “ABC12”, the storage unit 200 displays “D678” for “face”, “B898” for “hairstyle”, “C1120” for “clothes”, and “A178” for bottoms. "In association with" ABC12 ".

Thus, the avatar table manages the item ID data based on the coordinates of the avatar at that time in association with the user ID data.
[Item table]

  FIG. 3 is a diagram showing an item table according to an example of the preferred embodiment of the present invention.

  The storage unit 200 stores, in the item DB 202, for example, as an item table shown in FIG. 3, using item ID data as a key, image data, theme ID data, classification data, item attribute data (attribute 1, attribute 2, attribute 3), The selected number of times (the number of uses) is stored in association with each other.

  For example, an item whose item ID data is “C1120” is associated with image data representing the item, classification data such as “suit”, “spring”, “gray”, “business” and item attribute data. It can be read that the number of uses was 1000 times.

  Here, the theme ID data is data for identifying a theme such as “01” as “clothes”, “02” as “shoes”, and “03” as “cover”, and corresponds to the theme of the avatar table (FIG. 2). To do. For example, items having item ID data “C1120” and “C1130” have the same theme ID data “01” (clothing), and both appear in the clothing field of the avatar table.

  The control unit 100 refers to this item table according to the processing described later (FIGS. 4 and 5), selects items that constitute the user's avatar, and transmits corresponding image data to the terminal 20.

Here, the image data is exemplified as the data representing the substance of the item. However, the present invention is not limited to this, and may be moving image data such as MPEG, FLASH (registered trademark), 3GP, or audio data such as WAV, MP3. It may be. In the present invention, everything that can be handled as data constituting a part of the avatar that is finally transmitted to the terminal 20 is included.
[Main processing]

  FIG. 4 is a flowchart showing the flow of main processing according to an example of the preferred embodiment of the present invention.

  In step S <b> 11, the control unit 100 receives document data from the terminal 20. The document data is a web document such as a blog created on the terminal 20 and may be the entire web page or a part of the document data added / changed on the web page in a timely manner. The server 10 stores the received document data in the document DB 210 in association with the user ID data.

  In step S12, the morphological analysis unit 111 of the control unit 100 performs morphological analysis on the document data received in step S11, and decomposes the data into individual words (morphemes).

  In step S13, the feature data extraction unit 112 of the control unit 100 extracts a word characterizing the document data from the words decomposed in step S12, and uses this as feature data. Specifically, for example, a technique such as TF-IDF can be used, and one or a plurality of feature words are extracted by calculating the importance of each word.

  At this time, for example, when TF-IDF is used, the plurality of document data stored in the document DB 210 is referred to, the number of appearances and the number of appearance documents of each word in the document are calculated, and the importance is obtained.

  In step S14, the item data extraction unit 103 of the control unit 100 extracts item data (image data or the like) to be transmitted to the terminal 20 based on the feature data extracted in step S13. The processing contents will be described later with reference to FIG.

In step S15, the item data transmission unit 104 of the control unit 100 transmits the item data extracted in step S14 to the terminal 20.
[Item data extraction process]

  FIG. 5 is a flowchart showing a flow of item data extraction processing according to an example of the preferred embodiment of the present invention. This process corresponds to step S14 of the main process (FIG. 4).

  In step S21, the item data extraction unit 103 of the control unit 100 associates the feature data extracted in step S13 of the main process (FIG. 4) with the item attribute data of each item stored in the item table (FIG. 3). Is calculated. That is, the degree of relevance is highly evaluated for an item that matches feature data and item attribute data, and is stored as an index for item extraction.

  Here, the degree of relevance can be expressed by, for example, converting the number of words included in two pieces of data to be compared as points. Alternatively, when the words included in the item attribute data match, higher points may be given, and when the synonyms and synonyms match, lower points may be given. In addition, known techniques for improving the accuracy and efficiency of various relevance determinations can be applied to the present invention.

  Since the feature data is extracted from the document data described by the user, even if it has the same meaning, it may be extracted as a different word (synonym, synonym). Therefore, when calculating the relevance, the results may vary among the synonyms.

  Therefore, it is preferable to set the degree of association between synonyms high, or calculate the degree of association after collecting words having similar meanings into one representative word.

  In that case, for example, the synonym dictionary table shown in FIG. 6 can be used. The storage unit 200 stores synonyms in the synonym dictionary DB 211 as synonym dictionary tables in association with synonyms using the representative words as keys.

  For example, “shoe” and “shoes” are registered as synonyms for the representative word “shoes”, and the relevance of these words is set high. Alternatively, all these words are converted into “shoes” and the relevance is calculated, so that the same result as “shoes” can be obtained.

  Returning to FIG. 5 again, in step S22, the item data extraction unit 103 of the control unit 100 sequentially refers to the items with the highest degree of relevance calculated in step S21. finish. If there is an item with high relevance, the process proceeds to step S23.

  Here, when items are extracted in descending order of relevance, for example, two types of “shoes” may be extracted, which may cause a problem that the terminal 20 cannot coexist. Coexistence means that the terminal 20 can simultaneously express (display if image data). For example, if “suit” and “leather shoes” can be displayed simultaneously, it can be determined that “suit” and “T-shirt” are both themes of clothing, so only one can be displayed and cannot coexist.

  Therefore, the item data extraction unit 103 of the control unit 100 determines whether or not the already extracted item can coexist with the terminal 20 (step S23). refer. In this way, reference items that are determined to be coexistent are extracted (step S24).

  In order to determine whether or not coexistence is possible, data for grouping a plurality of items for each theme is stored in association with the item table (not shown). Alternatively, only one item can be extracted from the same theme by referring to the theme ID field of the item table (FIG. 3) (for example, ID data indicating classification such as “clothes”, “shoes”, and “covers”). Can also be realized. For example, in FIG. 3, only one of the items “C1120” (suit) and “C1130” (T-shirt) that have a common theme ID of “01” (clothes) can be selected.

  Here, as an embodiment of the present invention, all items of an avatar may be replaced, or a part of existing items may be replaced. When replacing all items, it may be determined whether the items extracted in this process can coexist. On the other hand, when replacing a part of an existing item, when an existing avatar is changed with the extracted item, it is determined whether or not the existing item can coexist.

  In step S25, the item data extraction unit 103 of the control unit 100 determines whether or not a predetermined number of items have been extracted. If it is determined that no item has been extracted, the process returns to step S22 to return the next item. To extract. When the extraction of the predetermined number of items is completed, the item data extraction unit 103 of the control unit 100 ends this process.

Note that the item data extracted by this processing has a high degree of relevance as described above, but can also be evaluated by weighting according to the number of uses of the item table (FIG. 3). For example, items that are frequently used (popular) are preferentially selected. By doing so, items that are frequently used including other users are preferentially extracted, and there is a possibility that the trend (fashion) of the world can be reflected.
[Avatar generation result]

  FIG. 7 is a diagram illustrating an example of a screen displayed by the terminal 20 after step S15 of the main process (FIG. 4).

  In this example, an avatar is displayed corresponding to each paragraph of the blog written by the user (for example, one day of a diary). Items are changed and displayed in association with words such as “play” and “soccer” extracted from the sentence, such as rough appearance and uniform appearance.

In addition, although the avatar is displayed for every paragraph in FIG. 7, the display form is not restricted to this, You may decide to display one avatar on the whole web page. In that case, feature data is extracted from the entire Web page, and an avatar composed of items related to the feature data is obtained.
