Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a document management apparatus that stores and manages, for example, a WWW page browsed by a WWW browser, a document created by a word processor, an editor, spreadsheet software, or other applications.
[0002]
[Prior art]
With the spread of PCs and word processors in recent years, digitization of documents in offices is progressing. In addition, with the development of the Internet and intranet, the use of e-mail has increased rapidly, and the above digitization has been accelerated further. As a result, many offices are overflowing with a large amount of electronic data, and the importance of efficiently organizing and managing them is increasing.
[0003]
For this reason, various document management apparatuses for efficiently managing these digitized documents have been developed. A certain apparatus has a feature in a document registration method, and can be registered in a database simply by dragging and dropping a file with respect to an icon on a desktop. In addition, a certain apparatus has a feature in a document search method. For example, a document can be searched in a natural language used everyday such as “material distributed at a meeting yesterday”. In addition, a certain apparatus specialized for electronic mail automatically retrieves received electronic mails and sorts them into folders for each sender, and can also perform searches by full-text search later. Recently, devices having these features have also appeared.
[0004]
As described above, various devices have been developed as document management devices. However, the registration function can be automatically registered only for a specific document such as an e-mail or the user has to perform a direct registration operation. It was a system.
[0005]
In addition, with the development of the Internet and WWW (World Wide Web), the rate of obtaining information through a WWW browser is increasing, and the importance of managing WWW pages is increasing. Software that automatically circulates a WEB site according to a URL registered in advance and collects a copy of a WWW page has been developed. However, it is not intended to register the page that you have seen.
[0006]
In addition, there is an apparatus having a function of registering a cache of a WWW page left on a disk by a WWW browser. If you use this function, you can register only the pages you see in the database, but there is a problem that you cannot register if the cache is cleared. In addition, since the cache becomes enormous in a short time, it is necessary to perform appropriate filtering before registration, but no device having such a filtering function has appeared so far.
[0007]
[Problems to be solved by the invention]
As described above, the registration function of the conventional document management apparatus is not provided with an automatic registration function for all items created, edited, and browsed by the user, that is, directly operated by the user. Either a registration operation has to be performed, or only a specific document such as the mail is targeted.
[0008]
In addition, there has been no device that has a function of automatically registering a large amount of information obtained through the WWW browser by filtering out the pages actually viewed by filtering.
[0009]
In view of the above problems, the present invention provides document management that facilitates document management by automatically creating index information that allows a user to search for documents that are actually created, edited, or viewed later. It is an object to provide a method and a document management apparatus using the method.
[0010]
In addition, the present invention automatically copies only documents that hit preset profile information from a vast number of documents obtained through a WWW browser to a local machine at the time of browsing, and further automatically creates index information for the copied data. It is an object of the present invention to provide a document management method and a document management apparatus using the document management method, which can easily manage documents by creating them manually.
[0011]
[Means for Solving the Problems]
The document management method of the present invention sets the timing for creating index information for searching stored documents, extracts attribute information about the document according to the set timing, and creates index information. By storing in association with the document, index information for a document actually created, edited, or viewed by the user can be automatically created, and the document can be easily searched later using the index information.
[0012]
Further, the document management method of the present invention provides an index for searching a document among the browsed documents based on the attribute information extracted from the browsed document and the profile information defining the attribute of the document to be selected. By selecting a document for which information is to be created, creating the index information from attribute information extracted from the selected document, and storing the selected document and the index information in association with each other, a WWW browser Of the enormous amount of documents (WWW pages) obtained through the process, only those that hit the preset profile information are automatically stored at the time of browsing, and index information for the stored data is automatically created. The stored WWW page can be easily searched using this index information.
[0013]
The document management apparatus of the present invention creates timing information by setting timing for creating index information for searching stored documents, and extracts attribute information about the document at the set timing to create index information And a storage means for storing the index information in association with the document, thereby automatically creating index information for a document actually created, edited, or viewed by the user, The document can be easily searched using this index information.
[0014]
Preferably, a search means for searching for a document based on the index information and a presentation means for presenting a search result by the search means together with at least the index information are provided.
[0015]
Further, the document management apparatus of the present invention is browsed based on extraction means for extracting attribute information from the browsed document, the extracted attribute information, and profile information defining attributes of the document to be selected. Selection means for selecting a document for creating index information for searching the document among documents, creation means for creating the index information from attribute information extracted from the selected document, and the selected document And storage means for storing the index information in association with each other, so that only documents that hit preset profile information from among a huge number of documents (WWW pages) obtained through a WWW browser are automatically viewed. And automatically create index information for this stored data, and later on this index information You can easily search for WWW pages stored using. Also, it is possible to generate effective index information for information that is updated daily such as a WWW page.
[0016]
Preferably, a search means for searching for a document based on the index information and a presentation means for presenting a search result by the search means together with at least the index information are provided. For example, by presenting in a tree format and a table format and displaying both in cooperation with each other, it is convenient for the user to find a desired document from the search result.
[0017]
Preferably, the image processing apparatus further includes search means for searching for a document having attribute information designated based on the profile information. Further, the apparatus further includes a deletion unit that deletes the document having the attribute information designated based on the profile information and the index information among the document and the index information stored in the storage unit. This makes it possible to search and delete documents more rationally and improve convenience in document management.
[0018]
Each of the above means can be recorded and distributed as a program to be executed by a computer on a storage medium such as a floppy disk or a CD-ROM. For example, the user interface unit 15, the file storage unit 8, and the index database 9 in FIGS. 1 and 11 are configured using hardware resources of the computer, and the other configuration units can be realized by programs executed by the computer. .
[0019]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings.
[0020]
(First embodiment)
FIG. 1 shows an example of the configuration of a document management apparatus according to the first embodiment of the present invention.
[0021]
The browsing unit 1 is for browsing, creating, or editing a digitized document such as a text document or an HTML document stored in the file storage unit 8. The browsing unit 1 is configured by an existing application such as an editor or a word processor in addition to the one created exclusively for the document management apparatus.
[0022]
The registration operation setting unit 2 sets an operation of the browsing unit 1 that is a timing for starting creation of index information for a document created, edited, and browsed by the browsing unit 1.
[0023]
The registered operation definition table 3 is for recording and storing the setting contents in the registered operation setting unit 2, and the registration control unit 4 performs registration control with reference to the registered operation definition table 3. For example, in the case of MS-Windows, the registration operation definition table 3 uses a registry or an INI file. The same system is used in other systems such as UNIX and MacOS.
[0024]
When the registration control unit 4 detects the operation of the browsing unit 1 based on the setting value of the registered operation definition table 3, the registration control unit 4 controls the keyword extraction unit 5, the attribute acquisition unit 6, and the index information creation unit 7 to create and register index information. Execute.
[0025]
The keyword extraction unit 5 extracts keywords from a document that has been browsed, created, and edited by the browsing unit 1. A keyword extraction method may be used, for example, a morphological analysis of a text part in a document, a word such as a noun is extracted, an appearance frequency of the noun is obtained, and some nouns with high appearance frequency are obtained. It may be a keyword. In addition, using a dictionary in which words that can be keywords for each field are registered in advance, matching may be performed between the document and the dictionary, and the matched word may be used as the keyword of the document.
[0026]
The attribute acquisition unit 6 acquires attributes other than keywords of the document being browsed, created, and edited by the browsing unit 1.
[0027]
The index information creation unit 7 generates index information for a document viewed or created and edited by the browsing unit 1 based on the keywords and various attribute values obtained by the keyword extraction unit 5 and the attribute acquisition unit 6.
[0028]
The file storage unit 8 stores various files of a document, and includes a hard disk and various removable media.
[0029]
The index database 9 stores and manages the index information created by the index information creation unit 7, and the search unit 10 performs a search using this index information.
[0030]
The search unit 10 searches the index database 9 based on a search request from the user, and informs the search result presentation unit 14 of the search result.
[0031]
The search result presenting unit 14 is composed of a table format presenting unit 11, a tree format presenting unit 12, and a cooperation control unit 13, and presents the search results in the search unit 10 to the user.
[0032]
The tabular form presentation unit 11 presents the search results as a one-line table. Present the results in a way that makes it easy to list results based on similarities and keywords.
[0033]
The tree form presenting unit 12 presents the directory structure in a tree shape in order to easily show where the retrieved document file is stored in the file storage unit 8.
[0034]
The cooperation control unit 13 performs control for linking both displays in accordance with a user's document selection operation performed on the table format presentation unit 11 and the tree format presentation unit 12.
[0035]
The user interface unit 15 includes an output device such as a display device, and various input devices such as a keyboard and a mouse. The user inputs various instructions, inputs a search expression, displays a document, and searches a document. The result is displayed.
[0036]
Next, registration timing and its setting by the document management apparatus of FIG. 1 will be described. Here, registration refers to creating index information for a document file already stored in the file storage unit 8 and registering the index information in the index database, which is called “document registration”. Sometimes.
[0037]
As an operation of the browsing unit 1 set as the registration timing, for example,
(1) Termination of browsing part 1 or closing of the browsing window
(2) File saving by user operation
The user only has to select one or both of these two through the registration operation setting unit 2. For example, if only (1) is set, all the documents that have been viewed or edited are registered. If only (2) is set, only the edited document is registered. When the browsing unit 1 has an automatic saving function, registration at the time of automatic saving can be added as an option (2). If both (1) and (2) are set, all the viewed and edited documents will be registered in the same way as setting only for (1), but the registration timing during editing is set only for (1). Is different. Registration at the time of saving is basic, and if you quit without editing after saving, registration at the end is not performed.
[0038]
The setting contents are written in the registration operation definition table 3 and referred to by the registration control unit 4.
[0039]
The above is the registration timing setting procedure.
[0040]
FIG. 2 is a diagram showing the structure of index information used in the document management apparatus. The attribute information about the document file (for example, ID number, file name, path name, file type, media type, creation date, title, Author) and a keyword extracted from the document, and one index information is created for each document.
[0041]
The ID number is an integer value data that is unique in all index information stored in the index database 9 in the order of creation of index information in the order of “1”, “2”, “3”.
[0042]
The file name is character string data representing the file name of the document file on the file storage unit 8.
[0043]
Similarly, the path name is character string data representing the path name of the document file on the file storage unit 8.
[0044]
The method of expressing the file name and path name depends on the OS on which the document management apparatus operates. For example, in the case of MS-Windows, “Document.txt”, “c: \ home \ My Document \ document.txt”, etc. It becomes the character string data.
[0045]
As shown in FIG. 3, the file type is predefined numerical data representing the file type. For example, the file type depends on the OS on which the document management apparatus operates, the application to be used, and the target file type. To do. For example, when a file of each application of MS-Office, a rich text format (RTF) file, and a standard text file are targeted on MS-Windows, the definition values shown in FIG. 3 are used.
[0046]
As shown in FIG. 4, the media type is predefined numerical data representing the type of file storage location, and depends on, for example, the OS on which the document management apparatus operates. For example, in the case of MS-Windows, a definition value as shown in FIG. 4 is used.
[0047]
The creation date / time is date-type data representing the date / time when the document file was created or the last update date / time.
[0048]
The title is character string data representing the title of the document file.
[0049]
The author is character string data representing the author who created the document file.
[0050]
The keyword is list-type data whose value is the keyword extracted from the text portion of the document by the keyword extraction unit 5.
[0051]
Next, processing operations for creating and registering index information by the registration control unit 4 will be described with reference to the flowchart shown in FIG.
[0052]
The registration control unit 4 monitors the operation set in the registered operation definition table 3 by the browsing unit 1, that is, the execution of the file saving or the ending operation of the browsing unit 1 (step S1). As a method for monitoring the execution of the operation, a method that is standardly used by an application that is resident in the system is used. For example, in the case of MS-Windows, a Windows message generated when the operation is performed is monitored, and the operation can be monitored by hooking the message. As another method, when an existing application is used in the browsing unit 1, it is possible to detect the set operation as a function of the application itself and to execute processing corresponding to the operation. . For example, in the case of MS-Word and MS-Excel, which are MS-Windows applications, it is possible to customize the operation of the application by rewriting the application command itself using the macro language VBA (Visual Basic for Application). A series of registration processing at the time of saving can be executed by modifying the command. It is also possible to create a macro that is automatically executed during the operation. For example, the process when an arbitrary file is closed with the Auto_Close () macro and the process when the Word itself is terminated with the Auto_Exit () macro can be described. Processing can be executed.
[0053]
When a preset save or end operation is detected (step S2), the registration control unit 4 activates the keyword extraction unit 5, and the keyword extraction unit 5 is browsed, edited, created, etc. A keyword is extracted from the selected document (step S3).
[0054]
Subsequently, the attribute acquisition unit 6 is activated, and each attribute value of the file name, path name, file type, media type, file creation date, title, and author is acquired from the browsing unit 1 (step S4).
[0055]
Subsequently, the index information creating unit 7 is activated, and the index information shown in FIG. 2 is created based on the keyword extracted by the keyword extracting unit 5 and each attribute value acquired by the attribute acquiring unit 6 (step S5).
[0056]
Subsequently, the index information creation unit 7 registers the created index information in the index database 9 (step S6).
[0057]
A method for acquiring each attribute value in the attribute acquisition unit 6, a method for creating index information in the index information creation unit 7, and a method for registering index information in the index database 9 in the index information creation unit will be described later. .
[0058]
Subsequently, it is checked whether or not the browsing unit 1 continues to operate (step S7). If the browsing unit 1 is still in operation due to registration at the time of saving or registration with the window closed, the operation returns to the monitoring state (step S1) again, and the above operations are continued.
[0059]
As described above, the registration control unit 4 creates and registers index information.
[0060]
Next, a method for acquiring each attribute value in the attribute acquisition unit 6 will be described.
[0061]
The file name and path name are obtained directly from the browsing unit 1. When an existing application is used in the browsing unit 1, attributes are acquired from the OS and application functions. For example, in the case of an application on MS-Windows, the attribute can be acquired by OLE automation or the like.
[0062]
The file type is obtained from the file name. For example, in the case of MS-Windows, the file type can be acquired from the extension portion of the file name.
[0063]
The media type is obtained by extracting the drive name from the path name and examining the drive type from the OS function.
[0064]
The file creation date and time is acquired using the OS function. For example, in the case of MS-Windows, it implements using each function of WindowsAPI.
[0065]
If the document file has a title as an attribute of the file itself, such as an MS-Word document file, the title is used as it is. If the document file does not have a title as an attribute, or if it is a document file whose attribute acquisition method is unknown, for example, the first sentence of the text portion of the document file is used as the title. When this one sentence exceeds the size of the character string field, up to that size is used as a title.
[0066]
The author uses the value as it is when the document file has the author's information as its own attribute. If the document file does not have the author information as an attribute or is a document file whose attribute acquisition method is unknown, the OS on which the document management apparatus operates has an API for retrieving the author of the document file. In this case, the author is acquired by this API function. When there is no API or when acquisition of a value fails, an empty character string is set as the value.
[0067]
When an existing application is applied to the browsing unit 1, if an attribute value as described above can be acquired as a function of the application, the attribute value is acquired by this function. For example, in the case of an MS-Windows application, it is possible to acquire many attribute values from the application using the OLE automation function.
[0068]
As described above, the attribute acquisition unit 6 acquires each attribute value.
[0069]
Next, a method for creating index information in the index information creating unit 7 will be described.
[0070]
First, create a new index,
(ID number) = (ID number of the index created immediately before) +1
The ID number determined by is set. The ID number may not be the above method as long as a unique value can be set for each index. For example, a method may be used in which an ID number that is missing due to deletion of an unnecessary index that has lost data at the index destination is preferentially assigned from a small number.
[0071]
Subsequently, each keyword extracted by the keyword extraction unit 5 is set. If no keyword is extracted, this field is an empty list type. When the number of keywords exceeds the upper limit of the maximum number of elements supported in advance as a list type, list types corresponding to the maximum number of elements are formed in the order detected as keywords.
[0072]
Finally, the attribute value of the file name, path name, file type, media type, file creation date / time, title, and author acquired by the attribute acquisition unit 6 is set.
[0073]
As described above, the index information creating unit 7 creates index information.
[0074]
Next, with reference to FIG. 6, an operation in which the index information creating unit 7 registers index information in the index database 9 will be described.
[0075]
In order to check whether the index information of the same document as the created index information already exists in the index database 9, the index information creation unit 7 uses the index information having the same path name as the index name in the index information. It is checked whether it exists in the database 9 (step S11).
[0076]
If there is no index information with the same path name, the created index information is newly registered in the index database 9 (step S12).
[0077]
When index information with the same path name already exists, the attribute values of the already registered index information and the created index information are compared, and when one or more different attribute values exist (step S13), Certain index information is updated with the index information created this time (step S14).
[0078]
If no different attribute value exists, the index information created this time is discarded because there is no change (step S15), and the process ends without registration.
[0079]
As described above, the index information creating unit 7 registers the index information in the index database 9.
[0080]
Next, a document search processing operation in the search unit 10 will be described with reference to FIG.
[0081]
A search expression for the index database 9 is input to the search unit 10 via the user interface unit 15 (step S21). The contents of this search expression depend on the index database 9. For example, when the index database 9 is a SQL (Structured Query Language) -based database, a search expression in an SQL sentence is used.
[0082]
Subsequently, the search unit 10 searches the index database 9 for index information using this search formula (step S22), receives the search result, and sends it to the search result presenting unit 14 (step S23). The search result presentation unit 14 presents the searched index information to the user interface unit 15.
[0083]
If there is no desired document in the search result presented in the search result presentation unit 14, the user can continue to discard the current search result and start the search again from step S21. If there are many search results and a desired document cannot be found, an additional search for the current search results can be performed (step S24). When performing an additional search, the current search results, that is, ID numbers of all index information of the searched document are stored as data in the memory (step S25), and the index information is retrieved from the index database 9 by the additional search. When acquiring the ID, only the one that matches the ID number on the memory may be taken out. In addition, by saving the search results of each search, it is possible to return to the previous search results or to perform a plurality of additional searches in parallel.
[0084]
As described above, the document search is executed in the search unit 10.
[0085]
Next, with reference to FIG. 8, the search result acquisition operation in the search result presentation unit 14 will be described.
[0086]
First, the user selects a desired document from the index information presented on the user interface unit 15 (step S31). Next, the file name and path name are extracted from the index information of the selected document (step S32), and the file name and path name are transmitted to the browsing unit 1 (step S33). The browsing unit 1 reads the corresponding document file from the file storage unit 8 from the file name and path name and presents it (step S34).
[0087]
As described above, the retrieval result presenting unit 14 obtains the retrieval result.
[0088]
Next, a method for presenting search results in the search result presentation unit 14 will be described. As shown in FIG. 9, the search result presentation unit 14 presents the search results on the display screen of the display device, in a tabular presentation window and a tree presentation window. In the tabular presentation window, the contents of the index information of each document are presented in tabular order from the top of the search score. The tree form presentation window presents the tree form based on the path information included in the retrieved index information.
[0089]
These two presentation windows operate in cooperation with each other by the cooperation control unit 13. For example, when an arbitrary document presented in the tabular presentation window is selected by clicking with the mouse or the like, the portion of the document on the tree presentation window is selected and can be recognized at a glance by highlighting or the like. Similarly, when an arbitrary document presented in the tree form presentation window is selected, the document on the table form presentation window is selected.
[0090]
For this purpose, the linkage control unit 13 serves to transmit the ID number of the index information for the document selected in one presentation window to the other presentation window.
[0091]
Further, the document file that has not been searched in each folder may be presented at the same time in the tree form presentation window (see FIG. 10). In this case, the searched file is highlighted so that it can be distinguished from the unsearched file at a glance.
[0092]
As described above, the search result presentation unit 14 presents the search result.
[0093]
(Second Embodiment)
The document management apparatus according to the second embodiment of the present invention is an example in which a WWW browser application is applied to the browsing unit 1 in FIG. 1, and a WWW page (on the WWW browser) browsed by a user as a document to be managed. Index information necessary for searching for the WWW page later is automatically created, and the desired WWW page is searched using the index information.
[0094]
By the way, in the case of a WWW page, the browsing entity is usually outside the local machine. In addition, the entity is often updated every day, and filing index information for the entity is often useless at a later date. For this reason, in the second embodiment, a function of creating a copy of the WWW page in the file system on the local machine is added, and index information for the copy is created and registered in the index database.
[0095]
In addition, when browsing WWW pages through a daily WWW browser, it is noticed that a huge number of pages are being browsed without knowing it. In the case of the method of registering all the documents (index information) viewed as in the first embodiment, there is a problem that the number of registrations becomes enormous. Therefore, in the second embodiment, a function is added in which profile information is registered in advance and filtering processing based on the profile information is performed on the browsed WWW page. Note that the browsing unit of the document management apparatus according to the second embodiment is not limited to the WWW browser 103 as shown in FIG. 11, and an existing application such as an editor or a word processor may be applied. The former function that creates an index by copying entities outside the local machine is used when viewing and editing document files on various removable media such as floppy disks and magneto-optical disks with applications such as editors and word processors. Can be applied. Further, the latter filtering process using profile information can be applied to a document file as it is.
[0096]
FIG. 11 shows a configuration example of the document management apparatus according to the second embodiment. In FIG. 11, the same parts as those in FIG. 1 are denoted by the same reference numerals, and different parts will be described. That is, in FIG. 11, the browsing unit 1 in FIG. 1 is replaced with the WWW browser 103, and the registration operation setting unit 2 and the registration operation definition table 3 in FIG. 1 are profile setting unit 101, profile registration table 102, filtering unit 106, WWW. The page acquisition / storage unit 117 is replaced with a profile information presentation unit 117.
[0097]
The WWW browser 103 is configured by an existing browser application, but may be a dedicated one.
[0098]
The profile setting unit 101 is for setting profile information (see FIG. 12) used when the document filtering process performed by the filtering unit 106 is performed. As shown in FIG. 12, for example, a plurality of keywords and a plurality of keywords are set. URLs (Uniform Resource Locators) can be set.
[0099]
The profile registration table 102 stores the profile information set in the profile setting unit 101 as shown in FIG. 12 together with the set time in the table format shown in FIG.
[0100]
The filtering unit 106 compares the keyword extracted by the keyword extracting unit 5, the attribute value acquired by the attribute acquiring unit 6 with the latest profile information set in the profile registration table 102, and determines whether or not to perform registration. Tell the registration control unit 4. When the keyword and the attribute value extracted from the browsing WWW page match the profile information, the registration control unit 4 registers the WWW page.
[0101]
The WWW page acquisition / save unit 107 copies each object constituting the page browsed by the WWW browser 103 into a single folder onto the file storage unit 8.
[0102]
The profile information presentation unit 117 is for graphically presenting the contents of the profile registration table 102 in time series, and can also search and delete a WWW page based on the presented profile information (described later).
[0103]
FIG. 14 shows the structure of index information, which is composed of items of ID number, URL, folder name, head file name, title, creation date, keyword, filtering type, and hit keyword, and is registered. One is created for each page.
[0104]
The ID numbers are numbered in the order of creation of index information in the order of “1”, “2”, “3”... And are unique integer data in all index information in the index database 9.
[0105]
The URL is character string data representing the URL of the WWW page to be registered.
[0106]
The folder name is character string data representing the path name of the folder storing the WWW page copied on the file storage unit 8.
[0107]
The first file name is character string data representing the file name of the file in which the HTML document of the first page is copied among the files in the folder.
[0108]
The title is character string data representing the title attached to the WWW page to be registered.
[0109]
The creation date / time is date-type data representing the date / time when the copied file was created or the last update date / time.
[0110]
The keyword is list-type data whose value is the keyword extracted from the text portion of the WWW page by the keyword extraction unit 5. If no keyword is extracted, this field is an empty list type. When the number of keywords exceeds the upper limit of the maximum number of elements predetermined as a list type, list types corresponding to the maximum number of elements are formed in the order detected as keywords.
[0111]
The filtering type indicates in advance whether the filtering process for the WWW page to be registered was performed with a URL defined in the profile, with a keyword, with both, or with no filtering. The defined numeric data takes one of the defined values shown in FIG.
The hit keyword is list-type data whose value is a keyword that matches the keyword of the profile information among the keywords extracted from the WWW page when the filtering process is performed on the WWW page to be registered. . If filtering by keyword is not performed, this field will be an empty list type.
[0112]
Next, with reference to FIG. 16, processing for creating and registering index information in the registration control unit 4 will be described.
[0113]
It is monitored whether a new WWW page is displayed on the WWW browser 103 (step S41). As this monitoring method, a method that is standardly used by an application resident in the system is used. For example, in the case of MS-Windows, a Windows message generated when a new WWW page is displayed is monitored, and it is detected that a new WWW page is displayed by hooking the message.
[0114]
When the display of a new WWW page is detected (step S42), the profile registration table 102 is referenced to check whether a URL is registered as a profile (step S43).
[0115]
If the URL is not registered in the profile, the process proceeds to step S46. On the other hand, if the URL is registered in the profile, the process proceeds to step S44, where the attribute acquisition unit 6 is activated, and the attribute acquisition unit 6 acquires the URL of the WWW page from the WWW browser 103 (step S44).
[0116]
Next, the filtering unit 106 is activated, and the URL registered as a profile is compared with the URL of the current WWW page to check whether there is the same URL (step S45). If there is the same URL, the following process is executed. If there is no same URL, the registration process is interrupted, and the process returns to step S41 to monitor the WWW browser.
[0117]
Next, referring to the profile registration table 102, it is checked whether or not a keyword is registered as a profile (step S46). If no keyword is registered in the profile, the process proceeds to step S49. On the other hand, if the keyword is registered in the profile, the process proceeds to 47, where the keyword extraction unit 5 is activated to extract the keyword from the text information in the WWW page (step S47). Note that, as described above, the keyword extraction is performed by a method normally used in a normal filing system or search system.
[0118]
Subsequently, the filtering unit 106 is activated, and the keyword extracted from the WWW page is compared with the keyword registered as a profile in the profile registration table 102 and collated (step S48). When there is no matching keyword, that is, when the same keyword as the keyword registered as a profile does not exist in the WWW page, the registration of the WWW page is interrupted, the process returns to step S41, and the WWW browser is monitored again.
[0119]
Subsequently, it is checked whether or not there is index information having the same URL as the WWW page in the index database 9 (step S49). If there is no index information of the same URL, the process proceeds to step S51 and the subsequent registration process is executed. When index information having the same URL as the WWW page exists in the index database 9, a copy of the WWW page in the folder pointed to by the index information and each file constituting the browsed WWW page If no different file exists (Step S50), it can be determined that the same WWW page as that being browsed has already been registered. After completing the registration process, the process returns to step S41 to monitor the WWW browser again. On the other hand, if even one different file exists, the process proceeds to step S51, and the subsequent registration process is executed.
[0120]
In the WWW page registration process, first, the WWW page acquisition / save unit 107 is activated to create a copy of the WWW page in the file storage unit 8 (step S51). The copy is created using a method generally performed by an application having an automatic patrol function for WWW pages.
[0121]
Next, the attribute acquisition unit 6 is activated to acquire each attribute value of the folder name, the first file name, the title, and the creation time from the currently viewed WWW page and a copy of the WWW page (step S52). Of these, the title is acquired directly from the WWW browser 103. The folder name and the head file name are obtained by leaving information at the time of making a copy and reading it out. As the creation time, the creation time of the folder to be copied is acquired by the same method as in the first embodiment. Alternatively, the current time may be obtained using the clock function of the OS, and this may be used as the creation time. Also, the URL used in the process (step S44) is used.
[0122]
Subsequently, the index information creating unit 7 is activated, and index information is created based on the keyword extracted by the keyword extracting unit 5 and each attribute value acquired by the attribute acquiring unit 6 (step S53). The method for creating index information is the same as that in the first embodiment. The created index information is newly registered in the index database 9 (step S54). Thereafter, the process returns to step S41, the WWW browser 103 is monitored, and the above processing is continued until the browser is terminated.
[0123]
Next, the search processing operation for the registered WWW page will be described. The document management apparatus shown in FIG. 11 has two search functions, that is, a search function similar to that of the first embodiment performed by a search expression input to the search unit 10 and a search function from the profile information presenting unit 117. .
[0124]
First, the search processing operation performed by the search expression input to the search unit 10 will be described. Here, the operation of the search result presentation unit 14 is different from that of the first embodiment. The search result presenting unit 14 presents the retrieved WWW pages in a tabular format presentation window and a tree format presentation window as shown in FIG. In the tabular presentation window, the index information content of each WWW page is presented in tabular order from the top of the search score. In the tree format presentation window, the WWW pages having the same URL are grouped into one hierarchy and presented as a two-level tree structure as shown in FIG. These two presentation windows operate in cooperation with each other as in the first embodiment by the cooperation control unit 13.
[0125]
In the tree form presentation window, the tree display as shown in FIG. 18 in which the domain display portion of the URL is hierarchically arranged in order from the right element, that is, the first domain, can also be performed.
[0126]
Next, the search processing operation from the profile information presentation unit 117 will be described with reference to FIGS. 19 and 20.
[0127]
FIG. 19 shows an example of a display screen displayed on the display device by the profile information presentation unit 11. The profile information presentation unit 11 is a graphic display of the contents of the profile registration table 102 according to the time axis 201, and all URLs and keywords set as profiles are used for their respective periods (set as profile information. (Period) are displayed in the URL display area 204 and the keyword display area 205. For example, it is confirmed from the display in FIG. 19 that the URL “www.aaa.ddd.edu” is valid profile information from mid-November 1999 to the end of January 2000, and the keyword “network” is valid from the end of January 2000. it can. The display areas 204 and 205 can be scrolled left and right (in the time axis) by clicking the scroll buttons 202 and 203 attached to the left and right of the time axis 201 with a pointing device such as a mouse.
[0128]
Hereinafter, the search processing operation from the profile information presentation unit 117 will be described with reference to the flowchart shown in FIG.
[0129]
First, the user selects an arbitrary URL and keyword from the display screen shown in FIG. 19 displayed by the profile information presentation unit 117 (step S61). Hereinafter, a case where both a URL and a keyword are selected will be described as an example, but the same applies to the case where only one of them is selected. As a selection method, a method of clicking and selecting a line segment representing a URL and a keyword with a pointing device and a line segment 206 for designating a time indicated by a vertical dotted line as shown in FIG. There are two types of selection methods: a method of selecting by moving and overlaying on a desired URL and keyword line segment. In the latter case, it is also possible to select two URLs and keywords in a rectangular area surrounded by both line segments 206.
[0130]
Next, the search button 207 is pressed (step S62). Subsequently, when the selected URL and keyword are transmitted to the search unit 10 (step S63), the index information of the already registered WWW page is obtained by filtering type and URL by the filtering process performed on the URL and the keyword. The field search is performed for each field of the hit keyword (step S64).
[0131]
Subsequently, the search result is transmitted to the search result presentation unit 14, and the search result as shown in FIGS. 17 and 18 is presented in the same manner as the search result using the search formula (step S65).
[0132]
Thereafter, similarly to the search of the first embodiment, a WWW page is selected from the search result (step S66), and the file name and path name are acquired from the corresponding index information (step S67). Subsequently, the file name and path name are notified to the WWW browser 103 (step S68), and the WWW browser 103 reads the corresponding WWW page from the file storage unit 8 and presents it (step S69).
[0133]
Next, processing for deleting index information, a WWW page copy file, and profile information in the profile information presentation unit 117 will be described.
[0134]
In addition to the WWW page search function from the profile information described above, the profile information presenting unit 117 further stores the searched index information and a copy file of the WWW page from the index database 9 and the file storage unit 8, respectively. Are deleted from the profile registration table 102 respectively. With this function, it is possible to effectively delete the profile information set in the past that has become unnecessary, and the copy file and index information of the corresponding WWW page. The deletion process will be described below with reference to the flowchart shown in FIG.
[0135]
First, the user selects an arbitrary URL and keyword displayed on the profile information presentation unit 117 (step S71). Hereinafter, a case where both a URL and a keyword are selected will be described as an example, but the same applies to the case where only one of them is selected. As a selection method, a method of selecting by clicking a line segment representing a URL or a keyword with a pointing device, and a line segment 206 for designating a time indicated by a vertical dotted line as shown in FIG. 19 are moved left and right by the pointing device. There are two types of selection methods: a method of selecting by overlaying on a line segment representing a desired URL and keyword. In the latter case, it is effective to select a line segment representing a URL or keyword that was valid before the specified time, that is, only in the area on the left side of the line segment 206 indicating the time, or the time. It is also possible to select two URLs and keywords in a rectangular area surrounded by both line segments 206.
[0136]
Next, the delete button 208 is pressed (step S72). At this time, it is checked whether or not the same URL and keyword as the selected one exist other than the selected one (step S73). If they exist, these URLs and keywords are removed from the selection (step S74). Then, it is checked whether the selected URL or keyword remains (step S75). When it remains, it progresses to step S76, and when it does not remain, a process is complete | finished without deleting.
[0137]
Subsequently, the URL and the keyword are transmitted to the search unit 10 (step S76), and the index information of the registered WWW page by filtering processing performed with the URL and the keyword includes the filtering type, URL, and hit keyword fields. Is searched by field search for (step S77).
[0138]
Next, in the profile information presenting unit 117, all of the searched index information is filtered by the URL and keywords other than the index information selected from the field values of the filtering type, URL, and hit keyword. (Step S78). If it is filtered by another URL or keyword, the index information is removed from the deletion target (step S79). As a result of the above processing, if there remains index information to be deleted (step S80), the process proceeds to step S81, and if not, the process proceeds to step S84.
[0139]
The profile information presentation unit 117 acquires a file name and a path name from the index information to be deleted (Step S81). The profile information presentation unit 117 deletes the copy file of the corresponding WWW page from the file storage unit 8 (step S82), subsequently deletes the corresponding index information from the index database 9 (step S83), and finally registers the profile. The URL and the keyword, which are the profile information of the file of the WWW page deleted from the table 102, are deleted (step S84).
[0140]
Note that the present invention is not limited to the above-described embodiment, and can be implemented with appropriate modifications, for example, by combining the first embodiment and the second embodiment within a range that does not change the gist.
