detailed description

The present invention will be described in further detail below in conjunction with the accompanying drawings.

The provision of extended search items in the present invention can be realized through the interaction between network equipment and user equipment. Specifically, the user equipment sends the search sequence entered by the user in the search box to the network device; then, the network device obtains corresponding extended search items according to the search sequence, which includes but not limited to specific attributes corresponding to the search sequence Extended search tab of , where each category search option corresponds to one or more switchable category search options for search suggestion items; then, the network device provides the obtained expanded search items to the user equipment; then, the user equipment provides the user with Renders extended search terms.

Here, user equipment includes, but is not limited to, any electronic product that can interact with a user through input devices such as keyboards, touchpads, and voice-activated devices, such as computers, mobile phones, smart phones, PDAs, and tablet computers.

Here, the network device includes, but is not limited to, a network host, a single network server, a collection of multiple network servers, or a cloud formed by multiple servers. Here, the cloud is composed of a large number of hosts or network servers based on cloud computing (Cloud Computing), wherein cloud computing is a kind of distributed computing, a super virtual computer composed of a group of loosely coupled computer collections.

Furthermore, in the present invention, the network device can be used as a whole, or part of the network hosts/servers, or even a specific device installed in one or more network hosts/servers, such as an extension providing device, to interact with the user equipment and Provides extended search terms. Unless otherwise specified, in this document, the network device is used equally with the extension providing device, and the user equipment is used equally with the extension presenting device.

FIG. 1 is a flow chart of a method according to an aspect of the present invention, illustrating a process of providing extended search terms. As shown in Figure 1, in step S1, the user enters a search sequence in the search box; in step S2, the user's user equipment 1 sends the search sequence that the user has entered in the search box to the network device 2, correspondingly , the network device 2 receives the search sequence; in step S3, the network device 2 acquires extended search items corresponding to the search sequence according to the search sequence, including but not limited to at least one of extended search tags and classified search options; In step S4, the network device 2 provides the obtained extended search item to the user equipment 1, and accordingly, the user equipment 1 receives the (etc.) extended search item; in step S5, the user equipment 1 presents the (etc.) extended search item to the user ) to expand the search term for the user to select.

Specifically, in step S1, the user inputs a search sequence in the search box.

Here, the search box is used by the user to enter a search sequence to search. The search box can be provided in a variety of scenarios, including but not limited to pages, toolbars of various browsers, and user interfaces of various applications. For example, the search box can be displayed on the homepage of various search engines, various The navigation area of the page or various navigation pages are presented to the user. The present invention is not limited here.

In the above scenario, a search box is presented to the user so that the user can activate the search box to enter a search sequence, for example, the user moves the mouse cursor into the search box and clicks the mouse, at this time the search box is activated and the user can enter a search sequence.

Here, the search sequence refers to a character string input by the user in the search box for searching, which specifically includes but not limited to keywords, sentences, and other characters.

It should be noted that those skilled in the art should be able to understand that the user input search sequence needs to be understood in a broad sense, that is, the user can not only directly input the search sequence in the form of text, but also input in other forms, such as the user input a voice, the user device 1 The search sequence corresponding to this segment of voice can be obtained through voice recognition.

In step S2, the user device 1 sends the search sequence input by the user in the search box to the network device 2, and the network device 2 receives the search sequence accordingly. Here, any predetermined communication method can be used for data transmission between the user equipment 1 and the network equipment 2. For example, the user equipment 1 can send the search sequence input by the user to the network equipment 2 through the HTTP or HTTPS communication protocol. The present invention is not limited here.

Subsequently, in step S3, the network device 2 acquires one or more extended search items corresponding to the search sequence according to the search sequence.

Wherein, the extended search item is an extended search suggestion corresponding to the search sequence, which includes but not limited to extended search tags and/or category search options.

Extended Search Tab

Here, extended search tags correspond to specific attributes of the search sequence.

Specific attributes can characterize an aspect of a search sequence. For example, the search sequences "Sina", "Sohu", and "Netease" are all names of websites, and these search sequences have address attributes. For another example, the search sequences "Liu Shishi", "Yang Mi", and "Wu Qilong" are all names of people, and these search sequences have character attributes. For another example, the search sequences "Where are we going, Dad 2", "Chen Sheng", and "Master of Hypnotism" are all current hot spots, and these search sequences have the attribute of hot spots.

The extended search label is a search suggestion corresponding to a specific attribute of the search sequence, but it is presented to the user in the form of a label different from the normal search suggestion presented line by line in the drop-down box of the search box. For example, when the search sequence has an address attribute, such as the search sequence "Sina", the user may have an addressing requirement. Therefore, the extended search tags obtained by the network device 2 include but are not limited to the name of the first-level or second-level column of the website, such as " Home”, “Weibo”, etc. For another example, when the search sequence has character attributes, such as the search sequence "Liu Shishi", the user may have the need to know the relevant information of the character. Therefore, the extended search tags obtained by the network device 2 include but are not limited to various application fields surrounding the character. The name of the website, such as "encyclopedia", "tieba", "picture", etc. For another example, when the search sequence has a hotspot attribute, such as the search sequence "Where is Dad going 2", the user may have a need to know the current hotspot, and the extended search tags obtained by the network device 2 include but are not limited to those with the search sequence as the theme. Extended sequences earned on top searched sequences such as "list", "when's airing" and more.

According to the corresponding relationship between keywords-attributes-extended search tags, the network device 2 can pre-establish a search suggestion library. The following will describe how to obtain the corresponding extended search tag for each specific attribute by way of example.

1) Address attribute

For example, the network device 2 can first query a predetermined thesaurus to obtain keywords with address attributes, such as the names of various websites, such as "Baidu", "Sina", "Sohu" etc.; accordingly, the network device 2 can capture The navigation information of each website is obtained to obtain the names of columns at all levels of the corresponding website, and the names of columns at all levels in each website are used as extended search tags corresponding to the website names. Network device 2 stores the corresponding relationship of each keyword (such as "Sina")-attribute (such as "address")-extended search label (such as "home page", "microblogging"), thereby setting up a search suggestion library, and can follow the aforementioned means to update the search suggestion library periodically or based on other trigger conditions.

Alternatively, the network device 2 can directly query the search information database of the search engine. An inverted index table is stored in the search information database, in which keywords and corresponding pages are recorded, and the attributes of each keyword are marked and the pages The links between are also marked. Therefore, by querying the index information base, the network device 2 can obtain the keywords with address attributes and the link pages of the corresponding pages, and then analyze the URLs of these linked pages according to the regular expressions of the URLs, so as to obtain the corresponding website in each level. Sections and their names to build a library of search suggestions. Preferably, the network device 2 can also query the above-mentioned predetermined thesaurus to obtain keywords with address attributes, such as the names of various websites, and query the index information database according to these keywords to obtain the column names of each level corresponding to each of them, Thus building a search suggestion library.

2) Character attributes

For example, the network device 2 can also first query a predetermined thesaurus to obtain keywords with character attributes, such as various names and community names, specifically the former such as "Liu Shishi" and the latter such as "maroon5"; subsequently, the network device 2 can Through massive data mining, such as data mining on the search logs of search engines, the search results accessed by a large number of users when searching for the aforementioned keywords with character attributes are collected, and these search results are classified/clustered, and the obtained Categories are used as extended search tags corresponding to keywords with person attributes. Among them, the network device 2 can classify/cluster the search results accessed by users based on each keyword with character attributes to obtain multiple groups, and use the application fields corresponding to the obtained groups as the extended Search tags; or, network device 2 can classify/cluster all search results accessed by users based on all keywords with personal attributes to obtain multiple groups, and use the application fields corresponding to the obtained groups as having personal attributes The extended search tab corresponding to the keyword. Alternatively, the network device 2 may be divided according to predetermined application fields, count the number of search results belonging to each application field in the search results accessed by users, and use the application fields in which the number of corresponding search results exceeds a predetermined threshold as the corresponding person. The extended search tags corresponding to the keywords of attributes or all keywords with person attributes.

3) Hotspot attributes

For example, the network device 2 can obtain search sequences whose user search volume exceeds a predetermined threshold within a predetermined period of time from the search logs of the search engine, that is, popular search sequences, and then the network device 2 can segment words for these popular search sequences to Obtain the popular keywords therein, a plurality of popular search sequences corresponding to each popular keyword therein, and other keywords and/or fragments in each popular search sequence among them, accordingly, the network device 2 converts these popular keywords As a keyword with a hotspot attribute, other keywords and/or segments in its corresponding popular search sequence are used as extended search tags corresponding to the keyword with a hotspot attribute, thereby establishing a search suggestion library.

Here, it should be noted that, the predetermined thesaurus used for querying address attributes and the predetermined thesaurus used for querying person attributes may be two independent thesauruses, or one thesaurus, which includes Multiple keywords and each keyword has multiple attributes. Moreover, the aforementioned search suggestion libraries established based on various attributes may also be independent of each other, or partly or completely integrated together.

It should also be noted that although the present invention only lists three attributes of the search sequence and their corresponding extended search tags, those skilled in the art should understand that this is an enumeration, not an exhaustive one. Therefore, it is only used for the purpose of explaining the present invention, and should not be construed as any limitation to the present invention. According to the needs of specific applications, other attributes of the search sequence can be used to obtain the corresponding extended search tags. The methods are not substantially different, and therefore should be included in the scope of patent protection of the present invention.

After the above-mentioned search suggestion library is established, after receiving the search sequence input by the user, the network device 2 can determine one or more specific attributes of the search sequence; then, the network device 2 obtains the corresponding extension according to at least one of the specific attributes. Search tags.

Wherein, the network device 2 can, for example, query the above-mentioned search suggestion library to obtain the specific attribute of the search sequence, and then query the search suggestion library established according to the above-mentioned methods according to the specific attribute of the search sequence to obtain the corresponding extended search tag. Wherein, when the search sequence has multiple specific attributes, the network device 2 may obtain the extended search tag corresponding to the specific attribute only based on one of the specific attributes, or may obtain the extended search tag based on part or all of the specific attributes. .

Category Search Options

Each category search option corresponds to one or more search suggestions. When multiple category search options are presented to the user in the form of tabs, the user can switch between each category search option by selecting a different tab, and further Browse the search suggestions corresponding to the toggled category search options. Here, the search suggestion items may be presented to the user in the tabs of the corresponding category search options in a common list form or label form.

Here, the network device 2 may, for example, query an existing search suggestion database to obtain a search suggestion sequence of the search sequence, and classify the obtained search suggestion sequence, so as to obtain corresponding multiple classified search options and at least one classified search option The corresponding search suggestion sequence. This process can be carried out in real time when the network device 2 receives the user's search sequence, or it can be established by the network device 2 according to the aforementioned process for a specific keyword, including the corresponding relationship between the keyword-category search option-search suggestion item The search suggestion library is used to provide the user with corresponding category search options and corresponding search suggestion items when the user's search sequence includes these keywords. Here, these specific keywords may be, for example, titles of film and television works.

Wherein, when the search suggestion items are presented to the user in a common list form, the search suggestion sequence under the corresponding category search option can be directly provided to the user as the search suggestion items. For example, for the user's search sequence "big bang", the network device 2 determines that the corresponding category search options include American dramas and Korean bands, and there are multiple search suggestion sequences corresponding to each category search option, such as the category search option "American drama" The following corresponds to "big bang season 1", "big bang season 2", etc., and the category search option "Korean band" corresponds to "big bang" lead singer", "big bang MV", etc.

When the search suggestion item is presented to the user in the form of a label, the network device 2 can deduplicate the search suggestion sequence under the corresponding category search option, that is, remove the repeated part of the search suggestion sequence and the search sequence and its corresponding category search option to reduce content presented in tabs, while providing more focused search suggestions to users. For example, for the user's search sequence "suspect tracking", the network device 2 determines that the corresponding category search options include the first season, the second season and the third season, and each category search option also corresponds to one or more search suggestions For example, the category search option "Season 1" includes "Suspect Tracking Season 1 Episode 1", "Suspect Tracking Season 1 Episode 2", etc. After deduplication, the corresponding search suggestion tags under each category search option can be Only "episode one", "episode two", etc. are rendered. Furthermore, the content presented in the label can be further reduced and highlighted by synonymous replacement, such as replacing the label "first episode" with the label "1".

Here, the category search option may not correspond to search suggestions in some cases. For example, the eighth season of bigbang has not yet been released, but its trailer has been released or the eighth season has been confirmed to be released, and the network device 2 can provide categories The search option "big bang season eight" may not correspond to any search suggestions. Alternatively, the network device 2 uses "trailer" as a search suggestion item under the category search option "big bang season eight".

Preferably, a category search option may further include sub-category search options, and each sub-category search option corresponds to one or more search suggestion items.

For example, the category search option "American drama" corresponding to the search sequence "big bang" can be further subdivided into subcategory search options first season, second season, third season, etc., and the category search option "Korean band" can include subcategory search options Level category search options Music, Videos, News, etc. In the adjacent area of each sub-category search option, such as its right side, expand/collapse function items, such as "+" and ">", can be provided. After the user selects this function item, the corresponding sub-category search option One or more search suggestion items can be expanded or collapsed on the user device 1 .

To sum up, according to the search sequence, the network device 2 can obtain the extended search tag and/or the category search option corresponding to the search sequence.

Preferably, the network device 2 can also obtain one or more common search suggestion sequences corresponding to the search sequence, and provide them to the user equipment 1 together with the extended search items obtained in the aforementioned manner in a subsequent step. For example, when presented to the user in the user device 1, the expanded search term may be presented in a prominent position in a search suggestion area, such as an upper area of a search suggestion list, where other general search suggestions may expand the search term. The lower area is presented to the user.

Subsequently, in step S4, the network device 2 provides the obtained extended search items to the user equipment 1 of the user, and accordingly, the user equipment 1 receives the extended search items provided by the network device 2 based on the search sequence input by the user.

In step S5, the user device 1 presents the extended search term to the user.

Afterwards, when the user selects an extended search item, more specifically, when the user selects an extended search label, or a category search option, or a sub-category search option, or a search suggestion item corresponding to a category search option, the network device may, according to the search sequence and the extended search item selected by the user to search, and provide a corresponding search result page.

Moreover, after the user selects the extended search item, the network device 2 returns to the corresponding search result page, which may still include a search box; The sequence and its selected extended search term serve as the search sequence that the user has entered, again providing the user with the corresponding extended search term. For example, when the search box on the search result page includes the search sequence input by the user and the extended search item selected by the user, the user device 1 may use the search sequence input by the user and the extended search item selected by the user as the search sequence entered by the user. The sequence is submitted to the network device 2 for new extended search terms.

Alternatively, if the extended search item selected by the user points to specific information, the network device 2 may directly return the specific information to the user. Among them, the specific information includes but is not limited to: pages, videos, audios, documents, etc.

The identification information of specific information can be included in the extended search item, and this identification information is used to point to specific information, such as the various names of specific information, the URL of the web page, the playback address of the video, etc.; when the user selects such an extended search item, the user Device 1 will send an information acquisition request to network device 2, and the information acquisition request includes at least the identification information of the specific information; then, network device 2 obtains the specific information according to the identification information and returns it to the user.

The extended search item may also include a link to specific information, such as the URL of the webpage, the playback address of the video, etc.; when the user selects the extended search item, the user device 1 obtains the corresponding specific information according to the pointed link.

Wherein, the extended search item is an extended search suggestion corresponding to the search sequence, which includes but not limited to extended search tags and/or category search options.

Extended Search Tab

Here, extended search tags correspond to specific attributes of the search sequence.

Specific attributes can characterize an aspect of a search sequence. For example, the search sequences "Sina", "Sohu", and "Netease" are all names of websites, and these search sequences have address attributes. For another example, the search sequences "Liu Shishi", "Yang Mi", and "Wu Qilong" are all names of people, and these search sequences have character attributes. For another example, the search sequences "Where are we going, Dad 2", "Chen Sheng", and "Master of Hypnotism" are all current hot spots, and these search sequences have the attribute of hot spots.

The extended search label is a search suggestion corresponding to a specific attribute of the search sequence, but it is presented to the user in the form of a label different from the normal search suggestion presented line by line in the drop-down box of the search box. For example, when the search sequence has an address attribute, such as the search sequence "Sina", the user may have an addressing requirement. Therefore, the extended search tags obtained by the obtaining device 21 include but are not limited to the names of the first-level or second-level columns of the website, such as " Home”, “Weibo”, etc. For another example, when the search sequence has character attributes, such as the search sequence "Liu Shishi", the user may have the need to know the relevant information of the character. Therefore, the extended search tags acquired by the acquisition device 21 include but are not limited to various application fields surrounding the character. The name of the website, such as "encyclopedia", "tieba", "picture", etc. For another example, when the search sequence has a hotspot attribute, such as the search sequence "Where is Dad going 2", the user may have a need to know the current hotspot, and the extended search tags acquired by the acquisition device 21 include but are not limited to those with the search sequence as the theme. Extended sequences earned on top searched sequences such as "list", "when's airing" and more.

According to the corresponding relationship between keywords-attributes-extended search tags, the network device 2 can pre-establish a search suggestion library. The following will describe how to obtain the corresponding extended search tag for each specific attribute by way of example.

1) Address attribute

For example, the network device 2 can first query a predetermined thesaurus to obtain keywords with address attributes, such as the names of various websites, such as "Baidu", "Sina", "Sohu" etc.; accordingly, the network device 2 can capture The navigation information of each website is obtained to obtain the names of columns at all levels of the corresponding website, and the names of columns at all levels in each website are used as extended search tags corresponding to the website names. Network device 2 stores the corresponding relationship of each keyword (such as "Sina")-attribute (such as "address")-extended search label (such as "home page", "microblogging"), thereby setting up a search suggestion library, and can follow the aforementioned means to update the search suggestion library periodically or based on other trigger conditions.

Alternatively, the network device 2 can directly query the search information database of the search engine. An inverted index table is stored in the search information database, in which keywords and corresponding pages are recorded, and the attributes of each keyword are marked and the pages The links between are also marked. Therefore, by querying the index information base, the network device 2 can obtain the keywords with address attributes and the link pages of the corresponding pages, and then analyze the URLs of these linked pages according to the regular expressions of the URLs, so as to obtain the corresponding website in each level. Sections and their names to build a library of search suggestions. Preferably, the network device 2 can also query the above-mentioned predetermined thesaurus to obtain keywords with address attributes, such as the names of various websites, and query the index information database according to these keywords to obtain the column names of each level corresponding to each of them, Thus building a search suggestion library.

2) Character attributes

For example, the network device 2 can also first query a predetermined thesaurus to obtain keywords with character attributes, such as various names and community names, specifically the former such as "Liu Shishi" and the latter such as "maroon5"; subsequently, the network device 2 can Through massive data mining, such as data mining on the search logs of search engines, the search results accessed by a large number of users when searching for the aforementioned keywords with character attributes are collected, and these search results are classified/clustered, and the obtained Categories are used as extended search tags corresponding to keywords with person attributes. Among them, the network device 2 can classify/cluster the search results accessed by users based on each keyword with character attributes to obtain multiple groups, and use the application fields corresponding to the obtained groups as the extensions corresponding to the keywords. Search tags; or, the network device 2 can classify/cluster all search results accessed by users based on all keywords with personal attributes to obtain multiple groups, and use the application fields corresponding to the obtained groups as having personal attributes The extended search tab corresponding to the keyword. Alternatively, the network device 2 may be divided according to predetermined application fields, count the number of search results belonging to each application field in the search results accessed by users, and use the application fields in which the number of corresponding search results exceeds a predetermined threshold as the corresponding person. The extended search tags corresponding to the keywords of attributes or all keywords with person attributes.

3) Hotspot attributes

For example, the network device 2 can obtain search sequences whose user search volume exceeds a predetermined threshold within a predetermined period of time from the search logs of the search engine, that is, popular search sequences, and then the network device 2 can segment words for these popular search sequences to Obtain the popular keywords therein, a plurality of popular search sequences corresponding to each popular keyword therein, and other keywords and/or fragments in each popular search sequence among them, accordingly, the network device 2 converts these popular keywords As a keyword with a hotspot attribute, other keywords and/or segments in its corresponding popular search sequence are used as extended search tags corresponding to the keyword with a hotspot attribute, thereby establishing a search suggestion library.

Here, it should be noted that, the predetermined thesaurus used for querying address attributes and the predetermined thesaurus used for querying person attributes may be two independent thesauruses, or one thesaurus, which includes Multiple keywords and each keyword has multiple attributes. Moreover, the aforementioned search suggestion libraries established based on various attributes may also be independent of each other, or partly or completely integrated together.

It should also be noted that although the present invention only lists three attributes of the search sequence and their corresponding extended search tags, those skilled in the art should understand that this is an enumeration, not an exhaustive one. Therefore, it is only used for the purpose of explaining the present invention, and should not be construed as any limitation to the present invention. According to the needs of specific applications, other attributes of the search sequence can be used to obtain the corresponding extended search tags. The methods are not substantially different, and therefore should be included in the scope of patent protection of the present invention.

After the above-mentioned search suggestion library is established, after receiving the search sequence input by the user, the acquisition device 21 can determine one or more specific attributes of the search sequence; then, the acquisition device 21 can obtain the corresponding extension according to at least one of the specific attributes. Search tags.

Wherein, the obtaining device 21 can, for example, query the above-mentioned search suggestion library to obtain the specific attribute of the search sequence, and then query the search suggestion library established in the above-mentioned ways according to the specific attribute of the search sequence to obtain the corresponding extended search tag. Wherein, when the search sequence has multiple specific attributes, the obtaining means 21 may obtain the extended search tag corresponding to the specific attribute only based on one of the specific attributes, or may obtain the extended search tag based on part or all of the specific attributes. .

For example, for the user's search sequence "suspect tracking", the obtaining device 21 determines that the corresponding category search options include the first season, the second season and the third season, and each category search option also corresponds to one or more search suggestions For example, the category search option "Season 1" includes "Suspect Tracking Season 1 Episode 1", "Suspect Tracking Season 1 Episode 2", etc. After deduplication, the corresponding search suggestion tags under each category search option can be Only "episode one", "episode two", etc. are rendered. Furthermore, the content presented in the label can be further reduced and highlighted by synonymous replacement, such as replacing the label "first episode" with the label "1".

Here, the category search option may not correspond to search suggestions in some cases. For example, the eighth season of bigbang has not yet been released, but its trailer has been released or the eighth season has been confirmed to be released, and the obtaining device 21 can obtain the category The search option "big bang season eight" may not correspond to any search suggestions. Alternatively, the obtaining means 21 uses "trailer" as a search suggestion item under the category search option "big bang season 8".

Preferably, a category search option may further include sub-category search options, and each sub-category search option corresponds to one or more search suggestion items.

For example, the category search option "American drama" corresponding to the search sequence "big bang" can be further subdivided into subcategory search options first season, second season, third season, etc., and the category search option "Korean band" can include subcategory search options Level category search options Music, Videos, News, etc. In the adjacent area of each sub-category search option, such as its right side, expand/collapse function items, such as "+" and ">", can be provided. After the user selects this function item, the corresponding sub-category search option One or more search suggestion items can be expanded or collapsed on the user device 1 .

To sum up, according to the search sequence, the obtaining means 21 can obtain the extended search tag and/or the category search option corresponding to the search sequence.

Preferably, the obtaining means 21 or other means in the network device 2 can also obtain one or more common search suggestion sequences corresponding to the search sequence, and combine them with the extended search items obtained in the aforementioned manner in subsequent steps It is provided to the user equipment 1 together.
