Description

  The present invention relates to a document information management apparatus and a document information management method capable of performing a search using a corresponding word as a keyword only by designating an arbitrary word in a hypertext document displayed on a screen and / or a non-hypertext document. .

  Conventionally, a paper document has been generally used as a document format commonly used in the world. However, hypertext has been born as an electronic document that can compete with a paper document for the first time by the development of the Internet / Intranet. This hypertext is a document written in HTML in a narrow sense, and in a broad sense, it is an inter-document (ie, a specific word, sentence, symbol, etc.) such as a PDF document from Adobe, a part of a SGML document in CALS, etc. Or all electronic documents that can be linked (in between a graphical button and a document).

  Specifically, hypertext is a collection of linked (associated) texts (digitized documents), and hierarchically and multi-dimensionally associated texts can be referred to in any order through a link structure. This is the basic concept of multimedia software. Therefore, the hypertext document includes information for forming a link structure (that is, information as hypertext) in addition to information visually provided to the user.

  On the other hand, in the computer world, a search engine is provided as a means for searching a document related to a specific word (keyword) for a large number of unspecified documents. In the conventional search engine, the keyword is not input on the document, but by an operation on a specific dialog.

  However, although the above hypertext has many advantages, it can only jump to linked pages (documents), so if you want information related to unlinked words, search There is a problem that it is necessary to start an engine etc. to perform a search (keyword search or full-text search), the work is complicated, and it is not easy to make a link, so it is not necessarily easy to use was there.

  Further, since conventional hypertext can be linked to only one document (page) with one button, there is a problem in that a plurality of documents cannot be referred to with one button. In particular, intranet documents are highly specialized, and there are a plurality of pieces of information to be referred to with a single button, so there is a problem that convenience and workability are poor.

  In addition, since the conventional search engine has a poor user interface compared to hypertext and the operation manner is different, it is poor in workability and convenience to perform a search by starting the search engine during hypertext operation. There was a problem. In particular, browser functions that display and operate hypertext screens are generally operated using only a pointing device such as a mouse. Therefore, keywords are entered by keyboard input on the search engine dialog during operation. The problem was that the work flow was hindered.

  The present invention has been made in view of the above, and it is an object of the present invention to improve convenience in document information management and document search, improve operability of search using keywords, and improve workability when performing a search. And

  Hereinafter, a document information management apparatus and a document information management method according to 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 means as a front end of the search engine means, and displays the search result by the search engine means on the screen of the browser means. It is intended to improve convenience in document information management and document search, improve operability of search, and improve workability when searching from hypertext.

  FIG. 1 shows a claim correspondence diagram of the document information management system according to the first embodiment, and is 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. And at least one database means or file means (which will be described only as database means for the sake of simplicity) 101, and a screen display of a hypertext document and a non-hypertext document. A browser means 102 having a browser function for performing an operation; a search engine means 103 having a search engine function for searching a corresponding document from the database means (or file means) 101 based on a designated keyword; Et al constructed.

  The browser unit 102 designates a word in the document displayed on the screen, transfers the designated word to the search engine unit 103 as a keyword used by the search engine unit 103, and also searches the search engine unit 103. Search engine corresponding interface means 104 for inputting a search result and displaying it on the screen. Here, as a search result by a search (keyword search or / and 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 in the vicinity of a specified word. To do.

  Further, the search engine means 103 performs a search using the keyword transferred from the browser means 102 (search engine correspondence interface means 104) and transfers the search result to the browser means 102 (search engine correspondence interface means 104). Interface means 105 is provided. Here, a pop-up menu list is created from the search result and transferred to the search engine correspondence 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 unit 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 document and non-hypertext document) 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 at least a display screen for displaying a document and a pointing device such as a mouse for performing a screen operation in addition to a main body device for executing an application. And a communication device for performing. Needless to say, the search engine compatible interface unit 104 is installed in the terminal device 202 as one function of application software for realizing a browser function. Further, the number of terminal devices 202 is not particularly limited, and it is a matter of course 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 equipped with application software for realizing the search engine function can be used. The terminal device 203 is connected on the network Net, and a plurality of terminal devices can be arranged. Further, the terminal device 202 serving as the browser unit 102 and the terminal device 203 serving as the search engine unit 103 may be used as a single terminal device. Specifically, the application software for realizing the search engine function may be installed in the terminal device 202 having the application software for realizing the browser function. Of course, the browser-compatible interface unit 105 is mounted on the terminal device 203 (together 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 corresponding interface means 105 starts the search engine means 103, and the search by the keyword is started.

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

  When the word is specified (designated) by the mouse operation of the terminal device 202 (S302), the search engine compatible 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 a word is performed by, for example, clicking a 2nd mouse button or the like in order to distinguish it from processing of a hypertext document. In addition, the keyword display is displayed in distinction from other words by reverse display or underline display.

  On the other hand, when the browser corresponding interface means 105 of the search engine means 103 inputs a keyword from the search engine corresponding interface means 104 of the browser means 102, the search engine means 103 is activated and a keyword is set in the keyword input item of the search engine means 103. This is performed (S351). Here, the browser-compatible interface unit 105 is a part of the application of the search engine unit 103. However, when the browser-compatible interface unit 105 always resides on the terminal device 203 and receives keyword transfer from the search engine unit 103, the browser engine interface unit 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 an object to be searched by the search engine means 103 (database means 101 to be searched) is set and designated in advance for the keyword search. Therefore, it is possible to target all database means 101 connected on the network Net by setting / designation, and it is also possible to target only a specific database means 101. Although not mentioned here, the browser unit 102 may be used to set and specify the database unit 101 to be searched.

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

  When the search engine interface unit 104 of the browser unit 102 inputs a list from the browser interface unit 105, the list is expanded into hypertext and overwritten (displayed) 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 means 102.

  Next, when the user operates the mouse to specify a desired document from the pop-up menu as shown by the cursor 403 in FIG. 4, the search engine corresponding interface unit 104 specifies 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 for 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 sword code of the corresponding document to the browser unit 102 (S391).

  When the source code is input, the browser unit 102 expands the hypercode document or the non-hypertext document (application document) and displays it on the screen (S309).

  As described above, according to the first embodiment, a search is executed using a word that is not linked by a word click operation as a keyword, and jumps from the clicked word to a search target page in the same manner as a hypertext button. be able to. Accordingly, it is possible to improve convenience in document information management and document search, improve operability of search using keywords, and improve workability when searching from hypertext. In other words, the document displayed on the screen of the browser unit 102 can be used as the front end of the search engine unit 103, and the search result searched by the search engine unit 103 can be displayed on the screen of the browser unit 102.

  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 the existing browser means as plug-in software.

[Embodiment 2]
The document information management system of 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 unit 103 that does not have the browser-compatible interface unit 105. That is, in the document information management system of the first embodiment, the browser unit 102 has the search engine correspondence interface unit 104, and the search engine unit 103 has the browser correspondence interface unit 105, so that it is displayed on the screen of the browser unit 102. In the second embodiment, the browser-compatible interface unit 105 is expanded by expanding the function of the search engine-compatible interface unit 104 of the browser unit 102. The existing search engine means 103 that is not installed can be used.

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

  FIG. 5 shows a claim correspondence diagram of the document information management system according to the second embodiment, and is 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. And at least one database means or file means (which will be described only as database means for the sake of simplicity) 101, and a screen display of a hypertext document and a non-hypertext document. And browser means 102 having a browser function for performing an operation, and search engine means 103 having a search engine function for searching a corresponding document from the database means 101 based on a designated keyword.

  The browser means 102 causes a word in the document displayed on the screen to be designated, activates the search engine means 103 as a keyword to be used by the search engine means 103, and 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 the 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 using the keyword is started.

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

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

  When the keyword input screen is input from the search engine unit 103, the search engine interface unit 106 does not display the input screen (that is, skips the display of the operation screen), and searches for the keyword recognized in step S603. The data is transferred to the means 103 (S605), and the recognized keyword is displayed (S606). Here, the specification (designation) of a word is performed by, for example, clicking a 2nd mouse button or the like in order to distinguish it from processing of a hypertext document. In addition, the keyword display is displayed in distinction from other words by reverse display or underline display.

  On the other hand, when the search engine means 103 inputs a keyword from the search engine corresponding interface means 106, the search engine means 103 executes a search process using the input keyword (S652). In this case, it is assumed that an object to be searched by the search engine means 103 (database means 101 to be searched) is set and designated in advance for the keyword search. Therefore, all database units 101 connected on the network Net by setting / designation can be targeted, and only a specific database unit 101 can be targeted. Although not mentioned here, the browser unit 102 may be used to set and specify the database unit 101 to be searched.

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

  On the other hand, when the search engine interface unit 106 inputs a search result based on a keyword, only the button is cut out from the search result to create a pop-up menu list (S607), and the list is expanded into hypertext to generate a keyword of the original document Is overwritten (displayed) as a pop-up menu in the vicinity of (S608).

  Next, when the user operates the mouse to specify a desired document from the pop-up menu, the search engine compatible interface unit 106 notifies the browser unit 102 of the URL (document specification) of the corresponding document described on the list. (S609). The browser unit 102 accesses the database unit 101 (Web server 201) in which the link destination document is stored from the URL, and makes a transfer request for 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 sword code of the corresponding document to the browser unit 102 (S691).

  When the source code is input, the browser means 102 develops the hypertext document or non-hypertext document (application document) and displays it on the screen (S611).

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

[Embodiment 3]
In the document information management system according to the third embodiment, a document file of a document displayed on a screen by a browser unit and used for specifying a keyword has a word table created by cutting out words included in the document file in advance. Further, the search engine-compatible interface means selects a plurality of additional character strings obtained by adding the preceding or succeeding characters or character strings to the character indicated by the cursor on the document displayed on the screen, and is added to the document. It compares and evaluates with words in the word table, and specifies an optimum word estimated to be pointed by the cursor as a keyword used in the search engine.

  In the document information management system of the present invention, a function for specifying a word specified in the browser means (search engine compatible interface means) is required. This word specifying function can be realized by various methods. This is not particularly limited in the first and second embodiments. 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 a word in a document such as Japanese. As a method of specifying this word, there are a method of preparing a special document structure created according to the purpose in advance 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.

  To the document file handled by the document information management system according to the third embodiment, a word table created by cutting out words included in the document file in advance is added. In a full-text search for a document in a language such as Japanese, Chinese, or 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 documents handled by this system. This word table functions as a word table for specifying words in the document on the screen of the browser means 102, and is 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, a word is cut out from the newly registered document by a technique such as morphological analysis, and then cut out. A word table is created from the obtained words and added to the original document file for rewriting registration.

  By always performing such processing, 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 shows a schematic flowchart of the document information management system according to the third embodiment. In the third embodiment, when the keyword is specified by the browser means 102, the browser corresponding interface means 105 starts the search engine means 103, and the search by the keyword is started.

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

  When a character is specified (designated) by the mouse operation of the terminal device 202 (S702), the search engine compatible interface unit 104 adds a character string (a nearby character string) obtained by adding some preceding and succeeding characters to the character. (S703), the extracted character string is compared with the word table (S704), the character string that matches the word in the word table is extracted as a word, and the 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 in the document displayed on the screen (here, the character “MA”) and the mouse button is clicked, and the character at the cursor position (the character “character“ Ma ”). The character at the cursor position designated in this way is identified as the specific character 702A (see FIG. 7) in step S702. The character is specified by, for example, clicking a 2nd mouse button or the like in order to distinguish it from the processing of the hypertext document.

  Next, a character string (a nearby character string) obtained by adding some preceding and following characters to the specific character is cut out. There are various methods for extracting the character string. 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, the character string in the vicinity cut out in step S703 indicates “when a plurality of buttons are marked, a plurality of pages are output to a display or a printer, as indicated by 703A in FIG. It becomes.

Subsequently, the nearby character string and the word table are compared, and a character string that matches the word in the word table is cut out as a word to identify the word. This word can be specified as follows, for example.
1) A character string “ni-ma” with one character added to the specific character “ma” is used as a temporary word, and whether or not a word matching this temporary word exists in the word table is checked. A temporary word is specified as a word.
2) If there is no match, the character string “ma”, which is a special character “ma” followed by one character, is used as a temporary word, and whether or not a word matching this temporary word exists in the word table is matched If there is a word, the provisional word is specified as the word.
3) If there is no match, the character string “ni-ma” is added to the specific character “ma” with one character before and after it, and the word table matches whether the word that matches the temporary word exists in the word table. If there is a word, the provisional word is specified as the word.
Thereafter, characters are added in the same manner, and the above processing is repeated until the extracted character string matches a word in the word table or (extracted character string) = (neighboring character string).

  Here, by specifying the word in step S705, “mark” is specified as a word as shown by 705A in FIG.

  In step S <b> 706 of FIG. 7, the identified word “mark” is recognized as a keyword, and the keyword is transferred to the search engine means 103. In step S707, the recognized keyword is displayed. FIG. 9 shows an example of keyword display. The keyword display is displayed separately from other words by reverse display or underline display.

  On the other hand, when the browser corresponding interface means 105 of the search engine means 103 inputs a keyword from the search engine corresponding interface means 104 of the browser means 102, the search engine means 103 is activated and a keyword is set in the keyword input item of the search engine means 103. This is performed (S751). Here, the browser-compatible interface unit 105 is a part of the application of the search engine unit 103. However, when the browser-compatible interface unit 105 always resides on the terminal device 203 and receives keyword transfer from the search engine unit 103, the browser engine interface unit 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 results using keywords (S753), and transfers the created list to the browser unit 102 (S754). Here, the names of retrieved documents and URLs (addresses) of those documents are described on the list.

  When the search engine interface unit 104 of the browser unit 102 inputs the list from the browser interface unit 105, the list is expanded into hypertext and overwritten (displayed) as a pop-up menu near the keyword of the original document (S708). ).

  Next, when the user operates the mouse 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 (document specification) of the corresponding document described on the list. (S709). 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 for the source code of the corresponding document (S710).

  Upon receiving the source code transfer request from the browser unit 102, the database unit 101 transfers the sword code of the corresponding document to the browser unit 102 (S791).

  When the source code is input, the browser means 102 develops the hypertext document or non-hypertext document (application document) and displays it on the screen (S711).

  As described above, according to the third embodiment, in addition to the effects of the first embodiment, the document file has a word table created by cutting out words included in the document file in advance, and search engine compatible interface means However, on the document displayed on the screen, select multiple additional character strings with the characters indicated by the cursor added to the characters before and after or a character string, and compare and evaluate with the words in the word table. Since the optimal word estimated to be used is specified as a keyword to be used by the search engine means, the keyword word can be specified accurately and efficiently.

[Embodiment 4]
The document information management system according to Embodiment 4 specifically shows another example of the 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 included in the hypertext document handled by the system in advance, and sets the link destination of the word as specific address information related to the activation of the search engine means. A set pseudo button is provided. Further, when the pseudo button is instructed by the cursor, the search engine corresponding interface unit specifies a word corresponding to the pseudo button as a keyword used in the search engine unit, and determines the search engine unit based on the URL of the pseudo button. It is something to start.

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

  The setting / creation of the pseudo button can be performed as follows by the terminal devices 202 and 203 connected to the network Net, the Web server 201, and the like. 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 etc., a word is cut out from the newly registered document by a technique such as morphological analysis, and then cut out. The specified word is specified as a pseudo button, the link destination URL is set, and the pseudo button is added to the original document file to perform rewrite registration.

  By always performing such processing, pseudo buttons can be added to all hypertext documents existing in the document information management system of 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 a pseudo button is specified by the browser means 102, the browser corresponding interface means 105 activates the search engine means 103, and a search using a keyword is started.

In addition, the display of keywords is displayed separately from hypertext buttons and other words by reverse display or underline display.

  On the other hand, when the browser corresponding interface means 105 of the search engine means 103 is accessed from the search engine corresponding interface means 104 of the browser means 102 in step S1003, the search engine means 103 is activated (S1051), and then in step S1004. When a keyword is input from the search engine correspondence interface unit 104, the keyword is recognized and a keyword is set in the keyword input item of the search engine unit 103 (S1052). Here, the browser-compatible interface unit 105 is a part of the application of the search engine unit 103. However, when the browser-compatible interface unit 105 always resides on the terminal device 203 and receives keyword transfer from the search engine unit 103, the browser engine interface unit Also plays a role as a trigger to start.

  When a keyword is set in step S1052, the search engine means 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 retrieved documents and URLs (addresses) of those documents are described on the list.

  When the search engine interface unit 104 of the browser unit 102 inputs a list from the browser interface unit 105, the list is expanded into hypertext and overwritten (displayed) as a pop-up menu near the keyword of the original document (S1006). ).

  Next, when the user operates the mouse 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 (document specification) 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 transfer request for 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 sword code of the corresponding document to the browser unit 102 (S1091).

  When the source code is input, the browser means 102 develops the hypertext document or non-hypertext document (application document) and displays it on the screen (S1009).

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

In order to identify, the word used as a keyword can be identified accurately and efficiently.

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

  In the document information management system according to the seventh embodiment, the search engine correspondence interface unit 104 displays a menu for specifying the search condition / output condition of the search engine unit 103 in the vicinity of the specified word. Search and output based on the menu item specified by the word and the 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 corresponding interface means 105 activates the search engine means 103 and the search by the keyword is started.

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

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

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

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

  On the other hand, when the browser corresponding interface means 105 of the search engine means 103 inputs a keyword from the search engine corresponding interface means 104 of the browser means 102, the search engine means 103 is activated and the keyword of the search engine means 103 and the search condition / output condition Is set (S1351). Here, the browser-compatible interface unit 105 is a part of the application of the search engine unit 103. When the browser-compatible interface unit 105 is always resident on the terminal device 203 and receives keyword transfer from the search engine unit 103, the browser engine interface unit 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 means 103 executes a search process using the set keyword and search condition (S1352).

  Subsequently, the browser-compatible interface unit 105 determines whether output of related information data is specified as an output condition (S1353). Here, in the case of outputting related information data, a pop-up menu list is created from the search result by 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 search engine interface unit 104 of the browser unit 102 inputs a list from the browser interface unit 105, the list is expanded into hypertext and overwritten (displayed) as a pop-up menu near the keyword of the original document (S1308). ).

  Next, when the user operates the mouse 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 (document specification) of the corresponding document described on the list. (S1309). 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 for the source code of the corresponding document (S1310). Similarly, when the URL of 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.

  Upon receiving the source code transfer request from the browser unit 102, the database unit 101 transfers the sword code of the corresponding document to the browser unit 102 (S1391).

  When the source code is input, the browser means 102 develops the hypertext document or non-hypertext document (application document) and displays it on the screen (S1311).

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

  The search condition / output condition is specified by, for example, clicking a 2nd mouse button or the like in order to distinguish it from hypertext processing. The designated word is displayed in reverse or underline, for example.

  As a search condition, a simple search expression can be used. For example, the or search has no search expression, and the and search is performed by the following operation. First, as shown in FIG. 14, it is assumed that a condition indicated by the pop-up menu 1402 is set for the keyword 1401 and a condition (specified value) indicated by the pop-up menu 1404 is set for the keyword 1403. In this state, the cursor is moved to the keyword 1403 that has already been specified, the 2nd mouse button is turned ON, the cursor is moved to the keyword 1405 that has not been specified, and the 2nd mouse button is turned OFF. The symbol “∩” is generated. At this time, the same content as the pop-up menu 1404 is displayed as the pop-up menu 1406. In the case of and search, only the pop-up menu 1404 may be displayed.

  As another method, when the cursor is moved to the keyword 1403 that has already been specified, the 2nd mouse button is turned ON, the cursor is moved to the keyword 1405 that has not yet been specified, and the 2nd mouse button is turned OFF, the keyword 1403 becomes the keyword. It moves to the position 1405 and automatically returns to the original position (drag and drop) when the 2nd mouse button is turned off, and an AND symbol “∩” is generated from the keyword 1403 to the keyword 1405. At this time, the same content as the pop-up menu 1404 is displayed as the pop-up menu 1406.

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

  If you want to modify the contents of the specified popup menu (search conditions / output conditions), move the cursor to the specified popup menu and click the 2nd mouse button to display the popup menu again and specify it 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 2nd mouse button is clicked, execution of the search is instructed, and the condition is specified in step S1306 of FIG.

  FIG. 17 shows an example of a mouse operation when specifying an output destination of related information data. As shown in steps S1355 and S1356 of FIG. 13, the browser corresponding interface means 105 of the search engine means 103 sends the search result to the search engine corresponding interface means 104 of the browser means 102 as a pop-up menu list. The search engine corresponding interface unit 104 expands this list into hypertext and displays it as a pop-up menu 1701 in the vicinity of the original keyword. In this way, related information data (title, abstract, etc.) is displayed as a pop-up menu 1701 in the vicinity of the keyword. When the cursor is placed on the desired related information data on this pop-up menu 1701 and the 2nd mouse button is clicked, As shown in FIG. 18, an output condition pop-up menu 1801 is displayed. The output destination (in this case, the printer 2) can be specified by moving the cursor to this output condition item and clicking the 2nd mouse button.

  The search conditions and output conditions shown in FIGS. 14 to 18 are set as necessary, and are not limited to the above items. Moreover, it is not limited to using all said items. That is, only the items necessary for the individually constructed document information management system may be used.
