Or between a button consisting of a graphic and a document).

  Specifically, a hypertext is a collection of linked (associated) texts (digitized documents), and each of the hierarchically and plurally associated texts can be referred to in an arbitrary order through a link structure. This is the basic concept of multimedia software. Therefore, this hypertext document contains information for forming a link structure (that is, information as a hypertext) in addition to information visually provided to the user.

It is possible to improve the resistance.

  Hereinafter, a document information management apparatus and a document information management method of the present invention will be described in detail in the order of [Embodiment 1] to [Embodiment 7] with reference to the accompanying drawings.

[Embodiment 1]
The document information management system according to the first embodiment uses the document displayed on the screen of the browser as a front end of the search engine, and displays the search result by the search engine on the screen of the browser. It is intended to improve the convenience in document information management and document search, the operability of search, and the workability when searching from hypertext.

  FIG. 1 shows a claim correspondence diagram of the document information management system according to the first embodiment, in which a hypertext document described in advance in a hypertext description language such as HTML or / and a non-hypertext document described in an application such as a word processor. At least one database means or file means 101 storing a plurality of document files (hereinafter, simply referred to as database means for simplicity of description), and a screen display of a hypertext document and a non-hypertext document Browser means 102 having a browser function for performing operations and operations; search engine means 103 having a search engine function for searching a corresponding document from a database means (or file means) 101 based on a designated keyword; Et al constructed.

  The browser means 102 designates a word in the document displayed on the screen, transfers the designated word to the search engine means 103 as a keyword used by the search engine means 103, and Search engine corresponding interface means 104 for inputting a search result from the URL and displaying it on the screen. Here, as a search result by a search (keyword search and / or full-text search), a pop-up menu list is input from the search engine means 103 (browser-compatible interface means 105), and a pop-up menu is displayed near a specified word. I do.

  The search engine unit 103 performs a search using the keyword transferred from the browser unit 102 (the search engine corresponding interface unit 104), and transfers a search result to the browser unit 102 (the search engine corresponding interface unit 104). It has an interface means 105. Here, a pop-up menu list is created from the search results and transferred to the search engine compatible interface means 104.

  FIG. 2 shows a specific hardware configuration example of the document information management system according to the first embodiment. As the database means 101, a plurality of Web servers 201 connected to a network Net such as an intranet can be used. The Web server 201 has a large-capacity hard disk device, and documents (hypertext documents and non-hypertext documents) used in the system are stored in the hard disk device.

  As the browser means 102, a terminal device 202 such as a personal computer equipped with application software for realizing a browser function can be used. The terminal device 202 communicates via a network Net with a display screen for displaying at least a document, a pointing device such as a mouse for performing screen operations, in addition to a main body device for executing an application. And a communication device for performing the communication. As a matter of course, the search engine corresponding interface means 104 is mounted on the terminal device 202 as one function of application software for realizing the browser function. In addition, the number of terminal devices 202 is not particularly limited, and it is needless to say that a plurality of terminal devices 202 can be installed on the network Net as illustrated.

  As the search engine means 103, a terminal device 203 such as a personal computer on which application software for realizing the search engine function is installed can be used. The terminal device 203 is connected to the network Net, and a plurality of terminal devices 203 can be arranged. Further, it is also possible to use one terminal device as the terminal device 202 as the browser means 102 and the terminal device 203 as the search engine means 103. Specifically, the terminal device 202 having the application software for implementing the browser function may be equipped with the application software for implementing the search engine function. As a matter of course, the browser-compatible interface unit 105 is mounted on the terminal device 203 (along with the search engine unit 103) as one function of application software for realizing the browser function.

  The operation of the above configuration will be described with reference to FIG. FIG. 3 is a schematic flowchart of the document information management system according to the first embodiment. In the first embodiment, when a keyword is input by the browser means 102, the browser-compatible interface means 105 activates the search engine means 103, and a search based on the keyword is started.

  First, the browser unit 102 displays a document on the screen (S301). In this state, the search engine corresponding interface means 104 starts operating.

  When a word is specified (designated) by the mouse operation of the terminal device 202 (S302), the search engine corresponding interface unit 104 recognizes the word as a keyword (S303), and transfers the keyword to the search engine unit 103. (S304), the recognized keyword is displayed (S305). Here, the specification (designation) of the word is performed, for example, by clicking a second mouse button or the like in order to distinguish it from the processing of the hypertext document. The display of the keyword is distinguished from other words by reverse display or underline display.

  On the other hand, when a keyword is input from the search engine corresponding interface unit 104 of the browser unit 102, the browser corresponding interface unit 105 of the search engine unit 103 activates the search engine unit 103 and sets a keyword in the keyword input item of the search engine unit 103. Performed (S351). Here, the browser-compatible interface means 105 is a part of the application of the search engine means 103, but always resides on the terminal device 203, and receives the transfer of the keyword from the search engine means 103. It also plays a role as a trigger to start.

  When the keyword is set in step S351, the search engine unit 103 executes a search process using the set keyword (S352). In this case, it is assumed that a search target (database means 101 to be searched) of the search engine means 103 is set and designated in advance in the search using the keyword. Therefore, it is possible to perform the setting for all the database units 101 connected to the network Net by setting / designating, or it is also possible to target only the specific database unit 101. Although not mentioned here, the setting and designation of the database means 101 to be searched may be performed by the browser means 102.

  Subsequently, the browser-compatible interface unit 105 creates a pop-up menu list from the search result using the keyword (S353), and transfers the created list to the browser unit 102 (S354). Here, the names of the retrieved documents and the URLs (addresses) of those documents are described in the list.

  When the list is input from the browser-compatible interface means 105, the search engine-compatible interface means 104 of the browser means 102 develops the list into hypertext and overwrites (displays) it as a pop-up menu near the keyword of the original document (S306). ). FIG. 4 shows a display example of the pop-up menu 402 displayed on the screen 401 of the browser unit 102.

  Next, when the user performs a mouse operation to specify a desired document from a pop-up menu as shown by a cursor 403 in FIG. 4, the search engine corresponding interface unit 104 determines the URL (document) of the corresponding document described on the list. Is specified to the browser means 102 (S307). The browser unit 102 accesses the database unit 101 (Web server 201) in which the linked document is stored from the URL, and makes a transfer request of the source code of the corresponding document (S308).

  Upon receiving the source code transfer request from the browser unit 102, the database unit 101 transfers the source code of the corresponding document to the browser unit 102 (S391).

  Upon input of the source code, the browser unit 102 expands the source code into a hypertext document or a non-hypertext document (application document) and displays it on the screen (S309).

  As described above, according to the first embodiment, a search is executed by using a word to which no link is provided as a keyword by a click operation of a word, and the clicked word is jumped to the search target page in the same manner as the hypertext button. be able to. Therefore, it is possible to improve the convenience in the document information management and the document search, the operability of the search by the keyword, and the workability in performing the search from the hypertext. In other words, the document displayed on the screen of the browser means 102 can be used as a front end of the search engine means 103, and the search result searched by the search engine means 103 can be displayed on the screen of the browser means 102.

  Note that the browser-compatible interface unit 105 can be realized by rewriting the API (Application Programming Interface) of the existing search engine unit 103. Further, the search engine corresponding interface means 104 of the browser means 102 can be realized by adding it to existing browser means as plug-in software.

[Embodiment 2]
The document information management system according to the second embodiment shows an example in which the same effect as that of the first embodiment is obtained by using the existing search engine means 103 without the browser-compatible interface means 105. That is, in the document information management system of the first embodiment, the browser means 102 has the search engine compatible interface means 104 and the search engine means 103 has the browser compatible interface means 105, so that the display on the screen of the browser means 102 is possible. In the second embodiment, the function of the search engine corresponding interface unit 104 of the browser unit 102 is extended, so that the browser corresponding interface unit 105 can be used as the front end of the search engine unit 103. In this case, the existing search engine means 103 not equipped with the above can be used.

  The basic hardware configuration example is the same as that of the first embodiment, and only different portions will be described here.

  FIG. 5 shows a claim correspondence diagram of the document information management system according to the second embodiment, in which a hypertext document previously described in a hypertext description language such as HTML or / and a non-hypertext document described in an application such as a word processor. At least one database means or file means 101 storing a plurality of document files (hereinafter, simply referred to as database means for simplicity of description), and a screen display of a hypertext document and a non-hypertext document And a search engine unit 103 having a search engine function of searching the database unit 101 for a corresponding document based on a designated keyword.

  The browser means 102 designates a word in the document displayed on the screen, activates the search engine means 103 as a keyword used by the search engine means 103, executes a search, It has a search engine corresponding interface means 106 for inputting a search result by a keyword from the search engine means 103 and displaying it on a screen.

  The operation of the above configuration will be described with reference to FIG. FIG. 6 is a schematic flowchart of the document information management system according to the second embodiment. In the second embodiment, when a keyword is input, the browser unit 102 activates the search engine unit 103, and a search based on the keyword is started.

  First, the browser unit 102 displays a document on a screen (S601). In this state, the search engine corresponding interface means 106 starts operating.

  When a word is specified (designated) by the mouse operation of the terminal device 202 (S602), the search engine corresponding interface unit 106 recognizes the word as a keyword (S603) and activates the search engine unit 103 (S604). ). Here, the activated search engine unit 103 transfers the keyword input screen to the search engine corresponding interface unit 106 as an existing process (S651).

  Upon input of the keyword input screen from the search engine means 103, the search engine corresponding interface means 106 does not display the input screen (that is, skips the display of the operation screen), and replaces the keyword recognized in step S603 with the search engine. The keyword is transferred to the means 103 (S605), and the recognized keyword is displayed (S606). Here, the specification (designation) of the word is performed, for example, by clicking a second mouse button or the like in order to distinguish it from the processing of the hypertext document. The display of the keyword is distinguished from other words by reverse display or underline display.

  On the other hand, when the search engine unit 103 inputs a keyword from the search engine corresponding interface unit 106, the search engine unit 103 executes a search process using the input keyword (S652). In this case, it is assumed that a search target (database means 101 to be searched) of the search engine means 103 is set and designated in advance in the search using the keyword. Therefore, it is possible to perform the setting for all the database units 101 connected to the network Net by setting / designating, or it is also possible to set only the specific database unit 101 as the target. Although not mentioned here, the setting and designation of the database means 101 to be searched may be performed by the browser means 102.

  Subsequently, the search engine unit 103 transfers the search result based on the keyword to the search engine corresponding interface unit 106 (S653).

  On the other hand, when the search result corresponding to the keyword is input, the search engine compatible interface unit 106 cuts out only the button from the search result to create a pop-up menu list (S607), expands the list into hypertext, and converts the list into the hypertext keyword. Is overwritten (displayed) as a pop-up menu in the vicinity of (S608).

  Next, when the user performs a mouse operation to specify a desired document from the pop-up menu, the search engine corresponding interface unit 106 notifies the browser unit 102 of the URL (specification of the document) of the corresponding document described on the list. (S609). The browser means 102 accesses the database means 101 (Web server 201) in which the linked document is stored from the URL, and makes a transfer request of the source code of the corresponding document (S610).

  Upon receiving the source code transfer request from the browser unit 102, the database unit 101 transfers the source code of the corresponding document to the browser unit 102 (S691).

  Upon input of the source code, the browser unit 102 expands the source code into a hypertext document or a non-hypertext document (application document) and displays the screen (S611).

  As described above, according to the second embodiment, in addition to the same effects as in the first embodiment, the existing search engine means 103 can be used as it is, so that it is easy to apply to an existing system. Yes, convenience can be further improved.

[Embodiment 3]
In the document information management system according to the third embodiment, a document file of a document which is displayed on a screen by a browser means and used for designating a keyword has a word table created by cutting out words included in the document file in advance. Also, the search engine-compatible interface means selects a plurality of additional character strings in which the character indicated by the cursor and the preceding or succeeding character or character string are added on the document displayed on the screen, and is added to the document. This is to compare and evaluate with words in a word table, and to specify an optimum word estimated to be indicated by the cursor as a keyword used in a search engine.

  In the document information management system of the present invention, a function for specifying a word specified by the browser means (search engine-compatible interface means) is required. However, since this function for specifying the word can be realized by various methods, the present invention is not limited to this. In Embodiment 1 and Embodiment 2, this is not particularly limited. Therefore, in the third embodiment, a word specifying function suitable for the document information management system of the present invention is specifically shown.

  Since the basic configuration and operation are the same as those in the first embodiment, only different portions will be described in detail here.

  By the way, it is not easy to specify words in a document such as Japanese. As a method of specifying this word, there are a method of preparing a special document structure created in advance according to the use, and a method of using an existing document structure. Here, as a document structure for the browser means 102 of the document information management system of the present invention, a document (a hypertext document and a non-hypertext document) having a word table created by cutting out words included in a document file in advance is used. To facilitate the identification of words.

  A word table created by extracting words included in the document file in advance is added to the document file handled by the document information management system according to the third embodiment. In a full-text search for documents in languages such as Japanese, Chinese, and Korean, an index file such as a character component table or a word table is added to the search target document. Therefore, a word table is added to all the documents handled by the present system, and this word table functions as a word table for specifying words in the document on the screen of the browser means 102, and is used as a search target. In documents, it functions as an index file for full-text search.

The word table can be created by the terminal devices 202 and 203 connected to the network Net, the Web server 201, and the like as follows.
First, at the time when the created document is registered, or at a time when the document information management system is not used at night or the like, words are cut out from the newly registered document by a method such as morphological analysis. A word table is created from the words that have been added, added to the original document file, and rewritten and registered.

  By performing such processing constantly, it is possible to add a word table to all document files existing in the document information management system according to the third embodiment.

  The operation of the above configuration will be described with reference to FIG. FIG. 7 is a schematic flowchart of the document information management system according to the third embodiment. In the third embodiment, when a keyword is specified by the browser means 102, the browser-compatible interface means 105 activates the search engine means 103, and a search based on the keyword is started.

  First, the browser unit 102 displays a document on the screen (S701). In this state, the search engine corresponding interface means 104 starts operating.

  When a character is specified (designated) by the mouse operation of the terminal device 202 (S702), the search engine corresponding interface unit 104 adds a character string before and after the character (a nearby character string). Is extracted (S703), the extracted character string is compared with the word table (S704), and a character string that matches a word in the word table is extracted as a word, and a word is specified (S705).

  Here, a specific processing example of steps S702 to S705 will be described with reference to FIG. For example, as shown in FIG. 8, the cursor 801 is moved to an arbitrary character (here, the character “ma”) in the document displayed on the screen and the mouse button is clicked, and the character at the cursor position (the character “character”) is clicked. ”). The character at the cursor position specified in this way is specified as the specific character 702A (see FIG. 7) in step S702. The specification of the character is performed, for example, by clicking a second mouse button or the like in order to distinguish it from the processing of the hypertext document.

  Next, a character string obtained by adding some characters before and after the specific character (a nearby character string) is cut out. There are various methods for extracting the character string, but as a simple method, a character string sandwiched between punctuation marks can be extracted as a nearby character string using punctuation marks before and after a specific character as identifiers. In this case, as shown by 703A in FIG. 7, the vicinity of the character string cut out in step S703 is described as "If a plurality of buttons are marked, a plurality of pages are output to a display or a printer. ].

Subsequently, a nearby character string is compared with the word table, and a character string that matches a word in the word table is cut out as a word to specify the word. The specification of this word can be performed, for example, as follows.
1) A character string “Ni-ma” obtained by adding the preceding character to the specific character “Ma” is used as a temporary word, and a word that matches the temporary word is compared in the word table to determine if it is a match. , A temporary word is specified as a word.
2) If they do not match, a character string “ma” obtained by adding one character after the specific character “ma” is set as a tentative word. If there is a word, the provisional word is specified as a word.
3) If the word does not match, the character string "ni-ma" is added to the specific character "ma" and one character before and after the character is assumed to be a tentative word. If there is a word, the provisional word is specified as a word.
Hereinafter, characters are similarly added, and the above processing is repeated until the cut-out character string matches a word in the word table or (cut-out character string) = (nearby character string).

  Here, in the specification of the word in step S705, the “mark” is specified as the word as indicated by 705A in FIG.

  In step S706 of FIG. 7, the specified word “mark” is recognized as a keyword, and the keyword is transferred to the search engine unit 103. In step S707, the recognized keyword is displayed. FIG. 9 shows a display example of a keyword, where the display of the keyword is distinguished from other words by reverse display or underline display.

  On the other hand, when a keyword is input from the search engine corresponding interface unit 104 of the browser unit 102, the browser corresponding interface unit 105 of the search engine unit 103 activates the search engine unit 103 and sets a keyword in the keyword input item of the search engine unit 103. Perform (S751). Here, the browser-compatible interface means 105 is a part of the application of the search engine means 103, but always resides on the terminal device 203, and receives the transfer of the keyword from the search engine means 103. It also plays a role as a trigger to start.

  When the keyword is set in step S751, the search engine unit 103 executes a search process using the set keyword (S752).

  Subsequently, the browser-compatible interface unit 105 creates a pop-up menu list from the search result based on the keyword (S753), and transfers the created list to the browser unit 102 (S754). Here, the names of the retrieved documents and the URLs (addresses) of those documents are described in the list.

  Upon input of the list from the browser-compatible interface means 105, the search engine-compatible interface means 104 of the browser means 102 develops the list into hypertext and overwrites (displays) it as a pop-up menu near the keyword of the original document (S708). ).

[Embodiment 4]
The document information management system according to the fourth embodiment specifically shows another example of a word specifying function suitable for the document information management system of the present invention. Since the basic configuration and operation are the same as those in the first embodiment, only different portions will be described in detail here.

  The document information management system according to the fourth embodiment cuts out a word contained in a hypertext document handled by the system in advance, and sets a link destination of the word as specific address information related to activation of the search engine means. The set pseudo button is provided. Further, when the pseudo button is pointed by the cursor, the search engine corresponding interface unit specifies the word corresponding to the pseudo button as a keyword used in the search engine unit, and specifies the search engine unit based on the URL of the pseudo button. It is something that starts.

  Therefore, a pseudo button is set in the hypertext document handled in the fourth embodiment in advance. Note that words set as normal buttons in the hypertext document are not set as pseudo buttons, and all main words other than the buttons are set as pseudo buttons (dummy buttons). The link destination URL of the pseudo button is set to the search engine unit 103 or a common specific URL.

  The setting and creation of the pseudo button can be performed by the terminal devices 202 and 203 connected to the network Net, the Web server 201, and the like as follows. First, at the time when the created document is registered, or at a time when the document information management system is not used at night or the like, words are cut out from the newly registered document by a method such as morphological analysis. The specified word is specified as a pseudo button, its link destination URL is set, and the pseudo button is added to the original document file and rewritten and registered.

  By performing such processing constantly, pseudo buttons can be added to all hypertext documents existing in the document information management system according to the fourth embodiment.

  The operation of the above configuration will be described with reference to FIG. FIG. 10 is a schematic flowchart of the document information management system according to the fourth embodiment. In the fourth embodiment, when the pseudo button is specified by the browser means 102, the browser-compatible interface means 105 activates the search engine means 103, and a search by a keyword is started.

  When the pseudo button is specified (designated) by the mouse operation of the terminal device 202 (S1002), the search engine corresponding interface unit 104 accesses the link destination URL set to the pseudo button (S1003). The character string (word) of the button is transferred to the link destination as a keyword (S1004), and the specified pseudo button (keyword) is displayed (S1005). Button and other words are displayed separately.

  On the other hand, if the browser-compatible interface means 105 of the search engine means 103 receives an access from the search engine-compatible interface means 104 of the browser means 102 in step S1003, the search engine means 103 is activated (S1051), and subsequently, in step S1004 When a keyword is input from the search engine corresponding interface means 104, the keyword is recognized and a keyword is set in a keyword input item of the search engine means 103 (S1052). Here, the browser-compatible interface means 105 is a part of the application of the search engine means 103, but always resides on the terminal device 203, and receives the transfer of the keyword from the search engine means 103. It also plays a role as a trigger to start.

  When the keyword is set in step S1052, the search engine unit 103 executes a search process using the set keyword (S1053).

  Subsequently, the browser-compatible interface unit 105 creates a pop-up menu list from the search result using the keyword (S1054), and transfers the created list to the browser unit 102 (S1055). Here, the names of the retrieved documents and the URLs (addresses) of those documents are described in the list.

  Upon input of the list from the browser-compatible interface means 105, the search engine-compatible interface means 104 of the browser means 102 expands the list into hypertext and overwrites (displays) it as a pop-up menu near the keyword of the original document (S1006). ).

  Next, when the user performs a mouse operation to specify a desired document from the pop-up menu, the search engine compatible interface unit 104 notifies the browser unit 102 of the URL (specification of the document) of the corresponding document described on the list. (S1007). The browser unit 102 accesses the database unit 101 (Web server 201) in which the linked document is stored from the URL, and makes a request to transfer the source code of the corresponding document (S1008).

  Upon receiving the source code transfer request from the browser unit 102, the database unit 101 transfers the source code of the corresponding document to the browser unit 102 (S1091).

  Upon input of the source code, the browser unit 102 expands the source code into a hypertext document or a non-hypertext document (application document) and displays the screen (S1009).

  As described above, according to the fourth embodiment, in addition to the effect of the first embodiment, the hypertext document cuts out a word included in the document in advance and sets the link destination of the word to start the search engine means. Since there is a pseudo button set as the specific address information (URL) involved, it is possible to efficiently specify a word serving as a keyword, and to easily start the search engine unit.

[Embodiment 5]
Embodiment 5 shows another example of the word specifying function suitable for the document information management system of the present invention. In this embodiment, the search engine-compatible interface means uses a cursor on a document displayed on the screen. A character string from the specified first character to the last character is cut out as a word, and the cut out word is specified as a keyword used by the search engine means. Since the basic configuration and operation are the same as those in the first embodiment, only a method for specifying a word by the search engine corresponding interface means 104 will be described here.

Is extracted (S703), words are extracted from the extracted character string by morphological analysis and evaluated (S1201), and an optimal word is specified (S705).

  Here, as shown by 703A in FIG. 12, the vicinity character string cut out in step S703 is described as "If a plurality of buttons are marked, a plurality of pages are output to a display or a printer. ]. When the morphological analysis is performed on the character string in the vicinity, the word “mark” can be specified as shown by 705A in FIG.

  As described above, according to the sixth embodiment, the search engine-compatible interface unit 104 cuts out an optimal word by evaluating it using a word cutting technique such as morphological analysis, and uses the cut-out word as a keyword to be used in the search engine unit 103. In order to do so, it is possible to accurately and efficiently specify a word to be a keyword.

[Embodiment 7]
The document information management system according to the seventh embodiment enables input of more search conditions and output conditions as compared with the first to sixth embodiments. The basic configuration is the same as that of the first embodiment, and only different portions will be described here.

  In the document information management system according to the seventh embodiment, the search engine corresponding interface unit 104 displays a menu for specifying search conditions and output conditions of the search engine unit 103 in the vicinity of the specified word. Search and output are performed based on a word and a menu item specified by a cursor.

  The operation of the above configuration will be described with reference to FIG. FIG. 13 is a schematic flowchart of the document information management system according to the seventh embodiment. In the seventh embodiment, when a keyword is specified by the browser means 102, the browser-compatible interface means 105 activates the search engine means 103, and a search based on the keyword is started.

  First, the browser unit 102 displays a document on the screen (S1301). In this state, the search engine corresponding interface means 104 starts operating.

  When a word is specified (designated) by operating the mouse of the terminal device 202 (S1302), the search engine corresponding interface unit 104 recognizes the word as a keyword (S1303) and displays the recognized keyword (S1304). ).

  Next, a pop-up menu for designating search conditions and output conditions is overwritten and displayed near the recognized keyword (S1305). Specifically, as shown in FIG. 14, when a keyword 1401 (the word “link”) is displayed, a popup menu of search conditions and output conditions is displayed near the keyword. By clicking a desired character on this pop-up menu (not shown), a corresponding item can be selected. As a search condition, a category can be specified, and a type of a DB (database to be searched) can be specified. As the output condition, output of related information and related information data can be specified, and an output destination (a device to output) can be specified. Can be specified.

  In step S1306, when the search condition / output condition is specified by a mouse operation described later, the search engine corresponding interface unit 104 transfers the recognized keyword and the specified search condition to the search engine unit 103 (S1307).

  On the other hand, when a keyword is input from the search engine compatible interface means 104 of the browser means 102, the browser compatible interface means 105 of the search engine means 103 activates the search engine means 103, and the keyword and the search condition / output condition of the search engine means 103 are input. Is set (S1351). Here, the browser-compatible interface unit 105 is a part of the application of the search engine unit 103, but always resides on the terminal device 203, and receives the transfer of the keyword from the search engine unit 103. It also plays a role as a trigger to start.

  When the keyword and the search condition / output condition are set in step S1351, the search engine unit 103 executes a search process based on the set keyword and search condition (S1352).

  Next, the browser interface unit 105 determines whether or not the output of the related information data is specified as the output condition (S1353). Here, in the case of outputting the related information data, a pop-up menu list is created from the search result by the keyword (S1355), and the created list is transferred to the browser means 102 (S1356). If the related information data is not output, only the related information URL is transferred to the browser means 102 (S1354).

  When the list is input from the browser-compatible interface means 105, the search engine-compatible interface means 104 of the browser means 102 develops the list into hypertext and overwrites (displays) it as a pop-up menu near the keyword of the original document (S1308). ).

  Next, when the user performs a mouse operation to specify a desired document from the pop-up menu, the search engine compatible interface unit 104 notifies the browser unit 102 of the URL (specification of the document) of the corresponding document described on the list. (S1309). The browser means 102 accesses the database means 101 (Web server 201) in which the linked document is stored from the URL, and makes a transfer request of the source code of the corresponding document (S1310). Similarly, when the URL of the related information is input from the browser-compatible interface unit 105, the database unit 101 (Web server 201) in which the linked document is stored is accessed from the URL and the source code of the corresponding document is accessed. Make a transfer request.

  The database unit 101 that has received the source code transfer request from the browser unit 102 transfers the source code of the corresponding document to the browser unit 102 (S1391).

  Upon input of the source code, the browser unit 102 expands the source code into a hypertext document or a non-hypertext document (application document) and displays it on the screen (S1311).

  Next, a method for designating (specifying) search conditions and output conditions by mouse operation will be specifically described with reference to FIGS.

  The specification of the search condition / output condition is performed by, for example, clicking a second mouse button or the like in order to distinguish it from the processing of the hypertext. The specified word is displayed in reverse video or underlined, for example.

  Also, a simple search formula can be used as the search condition. For example, the or search has no search formula, and the and search is performed by the following operation. First, as illustrated in FIG. 14, it is assumed that a condition indicated by a pop-up menu 1402 is set for a keyword 1401 and a condition (specified value) indicated by a pop-up menu 1404 is set for a keyword 1403. In this state, the user moves the cursor to the keyword 1403 that has already been specified, turns on the second mouse button, moves the cursor to the keyword 1405 that has not been specified, and turns off the second mouse button. The symbol “∩” is generated. At this time, the same content as the content of the pop-up menu 1404 is displayed as the pop-up menu 1406. In the case of an and search, only the pop-up menu 1404 may be displayed.

  As another method, the cursor is moved to the keyword 1403 that has already been designated, the second mouse button is turned on, the cursor is moved to the keyword 1405 that has not been designated, and the mouse button is turned off. The cursor is moved to the position 1405, automatically returns to the original position when the second mouse button is turned off (drag and drop), and an AND symbol “∩” is generated from the keyword 1403 to the keyword 1405. At this time, the same content as the content of the pop-up menu 1404 is displayed as the pop-up menu 1406.

  In addition, other search conditions and output conditions are also specified by clicking. For example, as shown in FIG. 15, “related information data, DB2, category C, display” is specified in the pop-up menu 1404 of the keyword 1403 and the keyword 1405 and search. This designation means that “search for two keywords“ and ”in category C of DB2 and output related information data to the display (during designation)”. The specified search condition / output condition is displayed as a pop-up menu 1402 of the keyword 1401. The pop-up menu 1402 means “search one keyword in category A of DB1 and output related information to printer 1 (specified)”.

  To modify the contents of the specified pop-up menu (search conditions and output conditions), place the cursor on the specified pop-up menu and click the second mouse button to display the pop-up menu again and specify again. It can be carried out.

  Thereafter, as shown in FIG. 16, when the cursor is placed on the “execute” button 1601 on the screen and the second mouse button is clicked, execution of the search is instructed, and the condition is specified in step S1306 in FIG.

  FIG. 17 shows an example of a mouse operation when the output destination of the related information data is specified. As shown in steps S1355 and S1356 in FIG. 13, the browser-compatible interface unit 105 of the search engine unit 103 sends the search result to the search engine-compatible interface unit 104 of the browser unit 102 as a pop-up menu list. The search engine-compatible interface unit 104 expands this list into hypertext, and displays the list as a popup menu 1701 in the vicinity of the original keyword. As described above, the related information data (title, abstract, etc.) is displayed as a pop-up menu 1701 near the keyword. When the cursor is moved to the desired related information data on this pop-up menu 1701 and the second mouse button is clicked, A pop-up menu 1801 for output conditions is displayed as shown in FIG. The user can move the cursor to the output condition item and click the second mouse button to specify the output destination (here, the printer 2).

  The search conditions and output conditions shown in FIGS. 14 to 18 are set as needed, and are not limited to the above items. Further, the present invention is not limited to using all of the above items. That is, only the items necessary for the individually constructed document information management system need be used.

  As described above, according to the seventh embodiment, in addition to the effect of the first embodiment, the search engine-compatible interface unit specifies search conditions and output conditions of the search engine unit near the specified word. Is displayed, and the search and output are performed based on the specified word and the menu item specified by the cursor, so that the workability and convenience of the user can be further improved.
