Description

  The present invention relates to a document management apparatus for searching and browsing electronically created text documents.

  With the recent enhancement of performance and storage capacity of personal computers and the spread of the Internet, filing systems for storing a large amount of electronic documents on personal computers are becoming popular.

  Conventionally, when a full-text search using free keywords is performed in such an electronic document filing system, a user can find a desired document from documents hit by the search by using a part of the document contents displayed on the search result screen. The main methods were to determine the relevance between them, and to actually browse and confirm documents. However, in these methods, as the number of documents hit by the search increases, a longer time is spent to find a desired document. For this reason, various methods have been studied in order to shorten the time for finding a desired document.

  For example, when displaying the search results, the similarity between the keywords used for the search and the document is calculated and the search results are displayed in descending order of the similarity, or the similarity relationship between the documents is visually determined using a diagram or the like. There is a way to express. The former approach uses words in a document to express the document as a vector based on the frequency of occurrence of the word and its weight, and improves the accuracy of similarity determination by calculating the vector distance as the distance between documents. (For example, refer to Patent Document 1). Further, as the latter, there is a method in which documents are displayed as icons in concentric circles having different radii, and the distance between the documents is determined based on the distance between the documents in the figure (for example, see Patent Document 2).

Japanese Patent Laid-Open No. 7-114572 JP 2001-350793 A

  However, in the similar document display format as described above, when there are many search documents and the distance between the documents is small, there is a problem that the icon representing the document overlaps and the user's desired document cannot be clearly displayed. .

  The present invention has been made in order to solve the above-described problems. Even when there are a large number of documents hit in the search, a document capable of quickly finding a desired document from the documents. The purpose is to obtain a management device.

  The document management apparatus according to the present invention stores an input document, outputs a document as a searchable text document, and analyzes a word / phrase of the text document, and outputs the analyzed result as word information. Document information extraction means, text information and document information storage means for storing word information output by the document information extraction means, and full text search for text documents stored in the document information storage means based on keywords specified by the user Document search means for outputting word information including keywords as a result, a display image for displaying the search result by the document search means, and a document for storing area information for displaying the searched text document in the display image The search display image storage means and the text document stored in the document search display image storage means are displayed on the designated display image. Forming a graphic representing attach response, those comprising a document retrieval and display control means for outputting the synthesized shapes to display images, and display means for displaying the output of the document retrieval and display control means.

  According to the present invention, when displaying the search result of a document, the document is projected and displayed on a display image and displayed so that the images do not overlap. There is an effect that document selection can be easily performed.

Hereinafter, an embodiment of the invention will be described.

The document information extraction unit 2 is a part that extracts word information from the text document output by the document registration unit 1.
The document information accumulating unit 3 is a part that accumulates text information output from the document registering unit 1 and word information obtained by the document information extracting unit 2 as document information.
The document search means 4 is a part that searches the text document of the document information with a keyword specified by the user and outputs the document information of the text document including the keyword as a search result.

The document retrieval display image storage means 5 is a part that outputs display information specified by the user and region information that defines the range in which the document is displayed as a graphic.
The document search / display control means 6 determines the figure representing the text document and the display coordinates of the figure from the search result output from the document search means 4 and the display image output from the document search display image storage means 5, and This is a part for outputting graphic information.
The display means 7 is a part for displaying the search results and graphic information output from the document search / display control means 6 on a display device such as a CRT monitor.

  Next, the operation of the document management apparatus will be described separately for the document registration method and the search / browsing method. FIG. 2 is a flowchart for explaining an operation for registering a document. First, the document registration means 1 inputs a document to be registered instructed by the user from a document on a scanner network (not shown) or the like (step ST101). In step ST101, the document shown in FIG. 3 is registered. This document to be registered is an electronic document that can be handled by a computer. The registered document illustrated in FIG. 3 is a repair report, which describes the part name, phenomenon, cause, treatment, completion date, charge, and the like.

  Next, the document registration means 1 determines the document number of the registered document (step ST102). The document number is assigned to a document in order to uniquely identify the document when handling the document. In step ST102, the number of stored documents plus 1 is added to the document to be registered. Here, the document to be registered is document number 1.

  Next, character extraction is performed (step ST103). For a character file whose text format is disclosed (such as a text document), for a document file whose data structure to be extracted is known according to the format, a character string is extracted according to the data structure.

  Next, word information extraction is performed (step ST104). The document information extraction means 2 extracts word information such as nouns and proper nouns by collating the characters of the document extracted by the document registration means 1 with a word dictionary held in advance. The word dictionary is created in advance by the user. Here, for example, as shown in FIG. 4, there is a word dictionary of “part name”, “cause”, and “date”, which is collated with the characters of the document. From the document shown in FIG. 3, “CD-ROM drive” is extracted as the component name, “spindle motor failure” as the cause, and “January 15, 2002” as the date.

  Next, storage processing is performed (step ST105). The document registration unit 1 stores the extracted text document, the designated document number, and the word information extracted by the document information extraction unit 2 in the document information storage unit 3.

  Next, a search / browsing method will be described. FIG. 5 is a flowchart for explaining the document search / browsing operation. First, the document search unit 4 performs a document search on the data stored as described above (step ST201). The user inputs a keyword into the document search means 4 using a keyboard (not shown). The document search unit 4 collates the document in the document information storage unit 3 with the input keyword, obtains a document number / page number including characters that match the keyword, and outputs the document content to the document search / display control unit 6. The display means 7 outputs the contents of the retrieved document.

  As a search example, “failure” is used as a search keyword. The document search means 4 collates the keyword “failure” with the document in the document information storage means 3 and outputs the matched document number / page number and its contents to the document search display control means 6. The display means 7 displays, for example, the document title and page number on a CRT monitor (not shown). A screen example of the document search result displayed by the display means 7 is shown in FIG. Since the document information storage means of each of the repair reports 1 to 6 displayed in FIG. 6 stores “failure” as one of word information by the document information extraction means, the repair reports 1 to 6 Is displayed. In addition to the search result output from the document search unit 4, the display unit 7 displays a display image selection button 10 for selecting a display image to be displayed in association with the search result.

  Next, the document search / display image storage means 5 selects and designates the image designated by the user (step ST202). Here, the display image is an image image used as a background image for displaying a document search result in front and a background image superimposed on the back, and a desired display image is selected by operating the display image selection button 10. be able to. For example, a list of background images is displayed by pressing the display image selection button 10 for selection, and a desired background image is selected from the list.

  The document search / display image storage means 5 stores the correspondence information of the image number, image title, and image file name and display image area information (coordinate information and attribute information) shown in FIG. 7 in association with the image number. For example, FIG. 8 shows a display image corresponding to the PC block diagram 11 of FIG. 7, and FIG. 9 shows its area information. The document search result is displayed in the coordinate area of the area information based on the word information of the area information. The region information is composed of attribute information related to the image file based on the word information and coordinate information in the attribute information.

  FIG. 8 shows a display image displayed when the PC block diagram 11 is selected in ST202. FIG. 9 is a diagram showing area information relating to the image of the PC block diagram 11 of FIG. 8, and the word stored in the word information column and its coordinates are stored in the document search display image storage means 5 in association with FIG. Has been. For example, the word information in FIG. 9 is “CPU” 13 and its coordinates (100, 50, 200, 200) indicate the coordinates of the rectangle 12 near the CPU block in FIG. In FIG. 9, the coordinates of the rectangle 12 are stored in the order of the upper left point (rectangle upper left x coordinate, rectangle upper left y coordinate) and lower right point (rectangle lower right x coordinate, lower right rectangle y coordinate).

  Next, a display operation when the user selects, for example, the PC block diagram 11 will be described. Subsequent to step ST202 in FIG. 5, the document is associated with the display image (step ST203). The document search / display control means 6 obtains the result of the document search means 4, the PC block diagram 11 designated by the user, and the area information of the image from the document search / display image storage means 5 and extracts words for each document of the search result. It collates with the word information of the area information shown in FIG.

  For example, “CD-ROM drive”, “spindle motor”, and “January 15, 2002” are added as document information to the document with document number 1 in the registered document shown in FIG. When this document information is matched with the word in the word information column of FIG. 9 and, as a result, coincides with the “CD-ROM drive” 14 of the number 3, the figure indicating the document according to the coordinate information of this “CD-ROM drive” 14 Draw.

  Next, the document search / display control means 6 draws a display image and a graphic indicating the document (step ST204). For example, assuming that the figure is “●”, the display range is obtained from the coordinate information (upper left corner coordinates and lower right coordinates) which is area information in order to draw the figure. The figure “●” is drawn within the predetermined display range with the specified drawing color so as not to overlap with the existing figure drawing.

  For example, the drawing position is sequentially shifted from the upper left corner of the display area with a predetermined width w and height h. For example, in the case of the “CD-ROM drive” 14 described above, the upper left x coordinate is 800, the upper left y coordinate is 50, and the next display image has an x coordinate (800 + w) obtained by shifting the width w to the upper left x coordinate and the upper left y coordinate. The coordinate 50 is displayed as the initial coordinate, and the width w is added to the x coordinate sequentially for each document.

  If the x coordinate exceeds the display range by shifting the width of the x coordinate, the x coordinate is set to the initial x coordinate (800), and then the height h is added to the y coordinate to obtain the y coordinate (50 + h). And draw in order so that the figures do not overlap. The above processing is executed for all the retrieval documents, and a graphic indicating the retrieved document is displayed on the monitor or the like by the display means 7 together with the display image.

In the case of the “CD-ROM drive” 14 used as an example, the upper left x coordinate is 800, the upper left y coordinate is 50, the lower right x coordinate is 950, and the lower right y coordinate is 200. Therefore, in order to draw the figures so as not to overlap, the width w needs to be 150 or more, and the height h needs to be 150 or more.
Further, the display means 7 may display the document content on a monitor or the like when the user selects a graphic indicating the document with a mouse or the like.

  As described above, according to the first embodiment, the retrieved document and the display image can be displayed on the monitor or the like without overlapping.
