Abstract

PROBLEM TO BE SOLVED: To retrieve and view additional information added not only to an original content but also to individual contents by the other user by adding additional information to the displayed content and managing inputted additional information while associating it with the additional content. SOLUTION: A package part 140 generates display data in a prescribed format in accordance with a content identifier and an annotation identifier, which are transferred from a content management part 110 and an annotation management part 130. A retrieval result display part 172 displays a retrieval result based on display data. When the display of the content is instructed, the contents and the content of the annotation are transferred from the content management part 110 and the annotation management part 130 to a content display part 171 and they are displayed. When the annotation is inputted to the content, the annotation input part 160 stores the inputted annotation in a data base server.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to a method for adding additional information to search result contents in a search system and a search system. Specifically, for the content obtained as a search result by the user using the search system,
The user who made the search can add arbitrary comments, and comments added by other users in the past and various additional information generated at that time (both are collectively referred to as annotations) , Or a system that can perform an efficient search by searching itself.

[0002]

2. Description of the Related Art An enormous amount of electronic information resources on a network represented by the WWW (World Wide Web) has already been accumulated, and it is certain that it will be increasingly accumulated in the future. At the same time, with the spread of the Internet, access to these information resources has become remarkably easy, and many people who do not have the specialized skills and knowledge of this kind of information search have started various search services. It is designed to be used.

[0003] Under these circumstances, there is a need for a technology that facilitates the retrieval of electronic information resources on a network as described above. For example, JP-A-7-319907 discloses that
A technique is disclosed in which a keyword input by a user is recorded and a comment can be added to the keyword by the user in order to repeatedly search using the same keyword. According to this technique, when a user wants to search for information on a specific product, for example, it is not necessary to input the same keyword each time, which is very convenient. Further, it is possible to refer to a comment added to the record of the keyword, such as a valid comment.

[0004] Further, Japanese Patent Application Laid-Open No.
Japanese Patent Publication No. 9761 allows a structured document to be searched by adding a comment.

[0005] When additional information (hereinafter referred to as "annotation") indicating the impression and impression of the content shared by a plurality of users on the network is provided to the user along with the corresponding content, the user is required to provide the information. The annotation can be used in various modes. Annotations are defined as information that is stored bidirectionally in relation to the original content of various information, such as comments, ratings, classifications, etc., provided by third parties for "content". I do.

[0006] The main role of annotation is to supplement and expand the original content. However, if annotations are shared among users, various kinds of support are possible. Therefore, an annotation management mechanism using an annotation database for accumulating and managing annotations has attracted attention.

Under such circumstances, the inventor of the present application has previously filed an application for the invention of Japanese Patent Application No. 8-195037. The present invention proposes a system for storing and managing annotations including impressions and impressions on contents in association with the contents. According to the invention of Japanese Patent Application No. 8-195037 described above, it is effective in selecting contents (social filtering) using reputation in a community such as a region or a workplace, and it is also possible to select a specific content. Unknown strangers mediated by the interests of others, encounters with known others,
It was also found that there was an effect of providing communication opportunities.

[0008]

By the way, when searching for conventional electronic information resources on the Internet, WW
When a structured document such as W is targeted, the part of the search that has been narrowed down in a normal search
(Usually called a page), and a normal keyword search will result in more pages than necessary. However, a general user often requests information that can give an overview of the whole, rather than such information at the end of fine page units.

[0009] Further, a search by inputting a keyword can perform only a one-sided search using only the keyword.
Previously, searching at the conceptual level or searching for a page like this could not be performed.

Further, the conventional search system for electronic resource information on a network does not support sharing of search information with other users. According to the invention disclosed in JP-A-7-319907, a user can add a comment to a search keyword, and according to the invention disclosed in JP-A-3-139761, it is possible to search for a document by adding a comment. It is possible. However, these are only cases where one user uses the system, and it is not possible for a plurality of users to mutually refer to and use comments.

[0011] In addition, Japanese Patent Application No. Hei 8-
The invention of 195037 is a technique for storing and managing annotations including impressions and impressions on contents in association with the contents, but does not intend to search for contents or search using contents.

The present invention has been made in view of such circumstances, and a user adds a comment to a search result of a content, and various information and attributes generated directly and indirectly with the comment. Can be added collectively as additional information, that is, as annotations, and the additional information can be stored and managed in association with the content to which it has been added, and furthermore, they can be added using arbitrary keywords, attributes, etc. It is an object of the present invention to add additional information to search result contents and to provide a search system in a search system which solves the above-mentioned various problems by enabling search for additional information.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing an example of a client-server type system configuration to which additional information is added to search result contents and a search system is applied in a search system according to the present invention.

As shown in FIG. 1, this system has a hardware configuration of a client terminal (CL) 100-1,
100-2, 100-3… 100-n, database server (Sv) 200 and other server (Sv) 210 are LAN (Local Area Network) lines
It is configured to be connected via LANL. In addition, LAN line LA
NL also connects to the Internet via an external electronic network NW.

The database server 200 accumulates various contents and annotations (to be described later) added to the contents, and manages the contents and the annotations. Each of the client terminals 100-1, 100-2, 100-3 ... 100-n allows the user to use the contents and annotations stored and managed in the database server 200 (search, display and editing associated therewith). Has become.

In the following description, the contents are stored in the database server 200, and the annotations are also stored in the database server 200. However, this is only an example, and the contents are stored in the client terminal. 100-1,100-2, 100-3 ... 100-n may be stored in the LAN line LANL to which 100-n is connected or the database connected to the network to which this LAN line LANL is connected, individual terminals, etc. The same applies to annotations. In short, client terminal 100-1, 100-2, both content and annotation
It may be stored in any location as long as it can be searched and accessed from 100-3... 100-n.

The other server 210 performs other processing (communication with another system, network, print processing, etc.) in the system.

As described above, the system of the present invention is built in a system configured in a client-server format. An example of a functional configuration of those systems is shown in a functional block diagram of FIG.

This system has a content management unit 110, an annotation management unit 130, and a package unit 140 as internal mechanisms. These internal mechanisms 110, 130,
140 is built in the database server 200 in FIG. The content management unit 110 includes a content search unit 111 for searching for a content according to a given search condition, and the annotation management unit 130 includes an annotation search unit 131 for searching for an annotation according to a given search condition. Have been. Furthermore,
This system has a search condition input unit 150, an annotation input unit 160, a content display unit 171 and a search result display unit 172 as user interfaces. These user interfaces are constructed in the respective client terminals 100-1, 100-2, 100-3... 100-n in FIG.

The search condition input unit 150 is provided for the user to input search conditions for searching for contents and annotations at each of the client terminals 100-1, 100-2, 100-3... 100-n. . Annotation input section
Reference numeral 160 is provided in each of the client terminals 100-1, 100-2, 100-3...

The content management unit 110 manages the content stored in the database, and performs a content search by the content search unit 111 in accordance with the search condition input from the search condition input unit 150 by the user.
FIG. 3 is a schematic diagram showing the contents of the content management table provided in the content management unit 110. In this content management table, for example, as shown in FIG. 3, a content ID for identifying the content itself is provided.
(C1, C2, C3 ...), creator ID (U1, U2, U3 ...) that identifies the creator of the content, title of the content, creation date of the content (year / month / day / hour / minute / second), storage pointer of the content body (Text pointer) is described.

The annotation management unit 130 has, for example, a content-annotation relation management table as shown in FIG. 4 and an annotation management table as shown in FIG.

The content-annotation relation management table shown in FIG. 4 includes an annotation ID (A11, A12, A13, A21...) For specifying each annotation, and a content ID for specifying the content to which the annotation is added. (C1, C2, C3 ...) are described.

The annotation management table shown in FIG. 5 includes an annotation ID (A11, A12, A13...) For specifying the annotation itself, and a registrant ID (U4, U5...) For specifying the person who registered the annotation. ), Content ID of the content to which each annotation is added
The relationship between (C1, C1, C1 ...) and the respective titles, the title of the annotation, the registration date, and the text of the annotation is described. Note that “suitable / unsuitable” corresponds to “Good” or “No Good” input by the user on the annotation input screen described later (see FIG. 8).

The package section 140 includes the content management section 11
0, display data (virtual package) in a predetermined format (for example, HTML format) is created according to the content identifier and the annotation identifier (title) transferred from the annotation management unit 130. Based on this display data,
The search result display unit 172 displays the search result, and when the display of the content is instructed, the content and the content of the annotation are transferred from the content management unit 110 and the annotation management unit 130 to the content display unit 171 and displayed. .

In the above-described system, the contents stored in the database server 200 are usually searched and used at each of the client terminals 100-1, 100-2, 100-3... 100-n (display, edit). Etc.) At that time, the user can input an annotation expressing an impression or impression of the content. For example, when the user inputs an annotation (title, text (comment)) for the content while the content of the search result is displayed on the display device of the client terminal, the annotation input unit 160 stores the input annotation in a database. While being stored in the server 200, information on the annotation is registered in the annotation management table (see FIG. 5) in the annotation management unit 130, and the annotation ID corresponds to the content in the content-annotation relation management table (see FIG. 4). Will be registered as follows.

For example, if a user searches for a content using the keyword “TV”, the keyword “TV” is input from the search condition input unit 150 of the client terminal of the user, and the content management unit 11
0 is given to the content search unit 111. Then, a search is performed by the content search unit 111, and the result is displayed on the content display unit 171. This search procedure itself does not differ fundamentally from the conventional procedure of searching for a content from a general keyword.

A certain keyword (in this case, “television”)
Is input, the search result is displayed on the content display section 171 of the user's client terminal as shown in the schematic diagram of FIG. In the example shown in FIG. 6, “(1) Sales Headquarters”, “(2) Semiconductor Development Dept.”, and “(3) Software Development Dept.” It is shown that there is a content with the keyword as. Therefore, if the user specifies any of these, for example, clicks with the mouse, the content itself (page) is displayed.

For example, when the user clicks on "(2) Semiconductor Development Headquarters" to view the content and displays the content, the process is performed in the procedure shown in the flowchart of FIG. An annotation input screen as shown in the schematic diagram of FIG. 8 is displayed.

On the display screen shown in FIG. 6, when the user performs an operation for designating the above-mentioned contents, the operation is detected (step S21), and an input window as shown in FIG. 8 is displayed on the screen (FIG. 8). Step S22). When the user inputs a text (comment) of the annotation and performs a predetermined operation (for example, clicking an OK button), the input annotation is added to the annotation added to the content shown in the screen of FIG. Is transferred to the database server 200 (step S23).

In the annotation input screen shown in FIG. 8, "Good" indicates "No Goo" when the keyword is deemed appropriate for the content of the search result.
"d" clicks a check box corresponding to the case where the user feels that the keyword is inappropriate for the content of the search result. By adding such annotations to individual contents, if a large number of contents searched for with a certain keyword are further searched with the "Good" annotation added to them and the search results are narrowed down, it is not very meaningful. It is possible to shake off (filter) content that is not.

The name of the user who entered the comment
(Including user ID, E-mail address, etc.) is added to each content as an annotation, and a large number of contents searched with a certain keyword can be further searched with the annotation of the user name added to it. It is also possible to narrow down search results, and in this case, it is possible to see the idea of a specific person and the like. If you search by your own user name (including user ID, E-mail address, etc.), you can use it as a memo. Furthermore, a window of "word" is prepared for the user to input a comment, and a word or a simple sentence can be input as a comment, and this corresponds to the text of the annotation.

In the database server 200, the annotation management unit 130 stores the transferred annotation in FIG.
Register in the annotation management table shown in
(Step S24). Specifically, the ID for specifying the annotation (for example, A11 representing the annotation added to the content C1), the registrant U4, the content ID of the content to which the annotation is added, the registration date, and the annotation text (comment) are registered. Is done. Also, this annotation ID (for example, A11) is registered and associated with the item of content C1 in the content-annotation relation management table shown in FIG.

As described above, the database server 20
In 0, various contents and annotations added thereto are stored in association with each other.

By the way, there are several possible uses of the annotations stored in the database server 200 as described above.

The first method is to browse the annotation log as it is. The fact that a comment has been added to the content means that the content itself is seen by many users, and the fact that a comment has been added means that many users are interested in the content. It means that it exists. Therefore, even if you simply browse the annotation log as it is, for some users, it is possible to know the trend of what other users using the search system are currently interested in There is a merit that becomes.

Second, in addition to the usual usage method of searching for content by keyword, annotations added to the content obtained as a result of the search are further searched by some keyword, and the resulting annotation is added. The content that is being extracted. By using this method, when the content obtained at the beginning is too large, users can quickly find the content they need by searching for annotations with keywords that are appropriate for the user. Becomes possible.

Third, the annotation itself is retrieved as an appropriate keyword, for example, a user name (ID) to which the annotation is added, the date and time when the annotation was registered, or a word that the user considers appropriate as a keyword, and the corresponding content is extracted. It is to be. According to such a method, it is possible to search for a content using a keyword that does not exist in the original content itself.

First, the first method will be described. In this case, it is basically possible to browse the entire log of the annotations registered in the database server 200, but in reality, the registration date is reversed (from the latest registration date to the older one). , Period designation, or today only. FIG. 9 is a schematic diagram of a screen displayed by the search condition input unit 150 on the user's client terminal for browsing such a comment history.

When the user clicks "latest" on the screen shown in FIG. 9, the processing is performed according to the procedure shown in the flowchart of FIG.
First, “date” in the annotation management table shown in FIG. 5 is searched by the annotation search unit 131 of the annotation management unit 130 (step S31), and a predetermined number of annotation IDs are acquired from the latest “date” to the past. (Step S32). Then, the respective data of the annotation management table corresponding to the predetermined number of annotation IDs obtained in this way are obtained (step S33), and they are packaged by the package unit 140 (step S34), and the display data is obtained as the search result. The data is transferred to the display unit 172 (step S35) and displayed.

As a result of such processing, a list of annotations of the search result as shown in FIG. 11 is displayed.
Note that in the example shown in FIG. 11, the title of the content and the text (comment) of the annotation are displayed.

When "specify period" is clicked on the screen shown in FIG. 9, a period input box (not shown) is further displayed, and the user can enter, for example, "1997, 01/01" in the box. −1997,01 / 31 ”, as in the case described above, the“ date ”in the annotation management table is searched by the annotation search unit 131 of the annotation management unit 130, and the specified range is specified. With "date"
ID is obtained. In the following, comments are displayed in the same manner as described above.

Further, when "Today" is clicked on the screen shown in FIG. 9, the date of the day is determined by the calendar function built in the system. “Date” is the annotation search unit 131 of the annotation management unit 130
To retrieve the annotation ID having the “date” of the day. In the following, comments are displayed in the same manner as described above.

Next, when a character string is entered in the "comment search" keyword box on the screen shown in FIG. 9, annotation search is performed using the entered character string as a keyword. Less than,
This will be described with reference to the flowchart of FIG. 12 showing the procedure at that time.

First, when the keyword is a registrant ID
(“YES” in step S41), the “registrant ID” of the annotation management table is searched by the annotation search unit 131 of the annotation management unit 130 (step S4).
2). When the keyword is "content title"
("NO" in step S41, "YES" in step S43),
"Content title" in the annotation management table
Is the annotation search unit 131 of the annotation management unit 130
(Step S44). When the keyword is “date” (“NO” in steps S41 and S43, step
“YES” in S45), “date” in the annotation management table is searched by the annotation search unit 131 of the annotation management unit 130 (step S46). Otherwise, the keyword is an arbitrary character string, and the character string of “body” in the annotation management table is stored in the annotation search unit 131 of the annotation management unit 130.
Is retrieved (step S47).

In any case, if the keyword input on the screen shown in FIG. 9 is found in the text of any of the annotations, the corresponding annotation ID is obtained (step S48) and the corresponding annotation ID is obtained. All the data of the annotation management table
(Step S49), these are packaged by the package unit 140 (Step S50), and the display data is transferred to the search result display unit 172 (Step S51) and displayed.

As a result of such processing, a list of comments of the search result as shown in FIG. 13 is displayed. In addition,
In the example shown in FIG. 13, the user ID is used as a keyword.
(A specific user name is "IWAYAMA"), and as a result of the search, two comments (annotations) are found, and the titles and texts (comments) of those annotations are displayed.

Next, a case will be described in which the content is searched for with a certain keyword, and the annotation attached to the content is further searched for with a keyword.

First, a content search is performed by a method similar to the conventional method. For example, it is assumed that a user having a keyword of “television” performs a search, and a large number of search results are obtained as shown in the schematic diagram of the display screen in FIG. However, in the example shown in FIG.
Although 81 search results were obtained, five search results are displayed on the actual screen.

When the content search results are displayed in this manner, the system of the present invention further includes a comment search box B2 for searching for annotations added to the content of the search results in FIG. It is displayed as shown. This comment search box
When B2 is clicked, a box B3 for entering a keyword for annotation search is displayed.
When a keyword is input to the search result, a search result is searched for a content to which an annotation corresponding to the newly input keyword is added. Fig. 15
Is a schematic diagram of a display screen showing the search results. In this case, as a result of performing an annotation search using “IWAYAMA” as a keyword, two cases are found.

A specific procedure for such an annotation search is shown in the flowchart of FIG. First, the user inputs a keyword for searching for content from the client terminal (step S61). The input keyword for content search is sent to the content management unit 110 by the search condition input unit 150 and sent to the content search unit.
111 performs a search. (Step S62). If there is content corresponding to the input keyword (“YES” in step S63), the content ID is packaged by the package unit 140 (step S64), and the display data is transferred to the search result display unit 172. (Step S6
5), displayed as shown in FIG.

Further, when the user inputs a keyword for annotation search as described above (step S66)
"YES"), the input keyword for the annotation search is sent to the annotation management unit 130 by the search condition input unit 150, and the annotation search unit 131 is added to the content already obtained as a result of the above search. An annotation corresponding to the present annotation ID is searched by a keyword (step S67). If there is an annotation corresponding to the entered keyword
(“YES” in step S68), the package unit 140 packages each identifier (step S69), converts the identifier into display data in a predetermined format (for example, HTML format), and transfers the display data to the search result display unit 172. The display is performed as shown in FIG. 15 (step S70). When the display of the actual contents and the contents of the annotation is instructed, the contents are transferred from the contents management unit 110 and the annotation management unit 130 to the contents display unit 171 and displayed.

Further, on the screen as shown in FIG. 14, "Go" indicated by reference numeral B4 or B5 is displayed.
If the user clicks the check box of “od” or “No Good”, “suitable / unsuitable” in the annotation management table shown in FIG. 8 is searched and displayed. This is the figure
It is also effective on the screen shown in FIG.

By the way, the above example is effective when the content is searched for by a certain keyword, and the search result is more than expected by the user. On the contrary, when the content is searched for by a certain keyword, the search result is obtained. In the case where it is expected that the content and the annotation are extremely small, it is also effective to simultaneously search for the content and the annotation using the same keyword. In this case, even if the content does not correspond to the keyword, the annotation attached to the content may possibly correspond to the keyword.

First, a display screen as shown in FIG. 17 is displayed, and a keyword is input. In the example shown in Figure 17, content and annotations (comments)
Will be searched for using the same keyword “TV”. Therefore, a combination of the content and the annotation in which the input keyword is included in at least one of the content and the body (comment) of the annotation added to the content is searched.

FIG. 18 is a flowchart showing a procedure for simultaneously searching for a content and an annotation.
When a keyword is input to each of the screens as shown in FIG. 17 (“YES” in step S81), and a search start button is clicked (“YES” in step S82).
), Content search unit 111 and annotation search unit 13
1. Both start the actual search of the database
(Step S83). The search procedure itself is the same as described above. If either the content or the annotation (comment) corresponding to the input keyword is found (“YES” in step S84), the package processing is performed by the package unit 140 as described above (step S85), and the display data is displayed. Is transferred to the search result display section 170 (step S86).

The display state of the result when the above-described simultaneous retrieval of the content annotation is performed is basically the same as the schematic view of the display screen shown in FIG. 15 described above.

[0071]

As described above in detail, according to the addition of the additional information to the search result content and the search system in the search system according to the present invention, the content is searched by the arbitrary keyword via the electronic network by the content search means. Is searched and displayed on the search result display means, and the content of the displayed search result is accessed and displayed by the content display means. Then, additional information is added to the content displayed by the search result display means by the additional information input means, and the additional information is managed by the additional information management means in association with the added content. It is possible to search and view not only content but also additional information added by other users to individual content.

Further, according to the system of the present invention, the user can search the additional information managed by the additional information management means with an optional keyword and display the search result on the search result display means. Becomes possible.
