[First Embodiment]
In this embodiment, a user who has created an electronic document A as shown in FIG. 2 using a personal computer equipped with the document management apparatus shown in FIG. 1 has already created an electronic document X as shown in FIG. The case of quoting the information will be described. It is assumed that the information source of the electronic document A is only the electronic document X, and there is no information source in the electronic information X. 1 is not limited to a personal computer, and may be a portable terminal, an MFP, or the like.
FIG. 4 is a flowchart showing processing up to acquisition of the original information source identification information in the processing in the document management apparatus according to the present embodiment. FIG. 5 is the main information source in processing in the document management apparatus according to the present embodiment. It is a flowchart which shows the process after acquiring identification information.
First, the user selects the image 12 shown in FIG. 3 to be cited in the electronic document X (S1), and instructs the personal computer to copy it to the clipboard (S2). Then, the personal computer acquires the image 12 of the electronic document X designated by the user on the clipboard (S3) and also acquires the identification information of the electronic document X that is the information source of the image (S4).
The identification information includes the name and ID of the information source, the type (electronic document, Web page, paper document, etc.), location (file path, URL, storage location, etc.), and the like. When the identification information of the original information source exists in the designated information (Yes in S5), the identification information of the original information source is acquired (S6). What is called the source of information here is the information source where the information first appeared when the information is repeatedly quoted, that is, the original location of the information.
Next, the user designates a predetermined position 11 (FIG. 2) of the electronic document A to which the image is cited (S11), and instructs the personal computer to paste the information acquired on the clipboard (S12). . Then, the personal computer confirms the clipboard, and if information exists (Yes in S13), the information is pasted (S14). If the information source identification information exists together with the information (Yes in S15), the information source identification information is pasted together with the information (S16).

In the first embodiment, the image copied from the electronic document X existing on the clipboard is pasted to the designated position 11 of the electronic document A, and at the same time, the electronic document X that is the information source acquired together with the image is identified. Information is added to the pasted image. Further, if there is identification information for identifying the information source that is the source of the information (Yes in S17), the information is also pasted together (S18).
In this way, when obtaining an image as information from an electronic document as an information source, the information source identification information is also acquired, and when information is added to the document, the information source identification information is also added to the information. To do. Further, if there is a source of information in the information, the identification information is also added. That is, the identification information of the document that is the parent of the information and the identification information of the document that is the source are added together with the cited information.
Here, images are cited as cited information. However, the present invention is not limited to this, and multimedia contents such as videos as well as characters, sentences and diagrams can be handled in the same manner.
If the source of information is an electronic document, the information to be cited and the identification information of the information source can be copied to the clipboard, but for information sources that cannot be copied directly to the clipboard, such as paper documents, It is desirable that the information source identification information can be manually input after being captured as an image by a scanner or directly input by a user.

As a method of adding the identification information of the information source, the identification information may be described using a structured document at a predetermined place of citation as shown in FIG. 6A, or as shown in FIG. 6B. The information of the information source may be added directly to the information quoted in the form of a tag, or other methods may be used.
6 (a) and 6 (b) both quote “pict1.jpeg” from an electronic file called “X.doc” in “C: \ Documents \”, and the source of information of “pict1.jpeg” is “Xyz.html” present in “http: //www.abc.com.pq/”.
In FIG. 6 (a), the name, type, and location are described as information source identification information, whereas in FIG. 6 (b), the location and name of the information source are described together. Not specified. Various combinations are possible for the description method of the identification information of the information source, and the present invention is not limited to these.
It is assumed that the user has created the electronic document A and stored it in an appropriate location in the storage device of the personal computer. Since it is described in the electronic document A that the image has been cited from the electronic document X, the electronic document A and the electronic document X are automatically associated with each other by the document management apparatus of the present embodiment. In the document A, system information registered as a child document of the electronic document X in the system to which the electronic document X belongs is created.

If the electronic document X is located at the highest level of the system, the electronic document A is a direct child document of the electronic document X, and therefore is arranged at a position following the electronic document X (FIG. 7A). If the electronic document X is arranged in the middle of the system, the electronic document A is arranged at a position following the electronic document X (FIG. 7B).
Here, it is assumed that there is a document referred to as an electronic document B, which is a part of the sentence from the electronic document X, as a child document of the electronic document X. When the related document search is performed using the electronic document A, since the electronic document A is cited only from the electronic document X in this example, the information source of the electronic document A is determined as the related document. The electronic document X and the electronic document B that is a child document of the electronic document X are obtained.
The evaluation value of the relevance between the electronic document A and the electronic document X that is the information source may be proportional to the amount of information cited, or only information about whether it is cited or not cited may be used. Other methods may be used. The related document search of this embodiment may be used alone or in combination with a keyword search, an image search, or the like.
In this way, by using the document management apparatus of the present embodiment, the user can search for related documents without being aware of search keys such as keywords and images. If a conventional keyword search, image search, or the like is combined with the document management apparatus of the present embodiment, a multifaceted search can be performed, and it can be expected that the search performance is improved.

[Second Embodiment]
In the first embodiment, the electronic document A uses only the electronic document X as an information source, but the second embodiment will explain a case where there are a plurality of information sources.
The method of acquiring information from the information source and adding it is as in the first embodiment. However, in the second embodiment, the electronic document A quotes a part of the text from the electronic document X and the electronic document Y, and the electronic document B quotes a part of the text from the electronic document X and the electronic document Z, respectively. Suppose you are. Further, it is assumed that none of the electronic document X, the electronic document Y, and the electronic document Z has an information source.
Since the identification information of the information source is described in each of the electronic document A and the electronic document B, these are automatically associated with the information source by the document management apparatus of this embodiment. Since the electronic document A and the electronic document B have two electronic documents as information sources, the electronic document A is an electronic document X and an electronic document Y, and the electronic document B is an electronic document X and an electronic document. It belongs to each system of Z. The same applies to the case where there are three or more information sources, and the information sources belong to the number of information sources.
Here, it is assumed that a related document search is performed using the electronic document A. Since the electronic document A is a child document of the electronic document X and the electronic document Y, three documents are selected as the related documents, that is, the electronic document B having the electronic document X as a shared information source.
The electronic document A and the electronic document B are both child documents of the electronic document X in the system, but since the information source shared by the two documents is only the electronic document X, the electronic document X and the electronic document Y are assumed to be information sources separately. When there is an electronic document C, the evaluation value of the relevance between the electronic document A and the electronic document B having one shared information source is the electronic document A and the electronic document C having two shared information sources. Compared with the evaluation value, it is desirable that the amount of quoted information is the same.
In addition, the electronic document A and the electronic document C quote a part of the sentence from the electronic document Y, but the evaluation value is higher when the same sentence is cited than when the different sentence is cited. It is desirable that
In other words, if you are quoting the same information from the same source, you are more likely to refer to the same content than when you are quoting different information from the same source. Therefore, it is desirable that the evaluation value is also determined to be higher according to this. Further, it is desirable that the evaluation value determination be higher as the number of information sources to be shared is larger.
Thus, by appropriately changing the evaluation value of the degree of association according to the number of information sources to be shared and the information to be shared, the target document can be obtained more reliably and easily.

[Third Embodiment]
In the third embodiment, a case where a system diagram is created based on identification information of an information source will be described.
Assume that the electronic document A and the electronic document B use the electronic document X as an information source, the electronic document X uses the electronic document Y as an information source, and the electronic document Z uses the electronic document Y as an information source.
When these electronic documents are represented in the systematic information, the electronic document X and the electronic document Z belong to the system of the electronic document Y (FIG. 8A), and the electronic document A and the electronic document B belong to the system of the electronic document X ( It can be expressed in the form of FIG. In addition, the two systems are connected via the electronic document X, the electronic document Y is located in the first hierarchy, which is the highest level of the system, and the electronic document X and the electronic document Z as the child documents are the electronic document Y in the second hierarchy. Furthermore, the electronic document A and the electronic document B, which are child documents of the electronic document X, can also be represented as hanging on the electronic document X in the third hierarchy (FIG. 8C).
In order to search for a related document based on the correlation rather than the document evaluation value, it is desirable that the correlation of the document is expressed in a form that can be easily recognized visually. In order to realize this, the system information obtained previously is displayed to the user in the form of a system diagram, and a link to a document corresponding to each node of the system diagram is pasted.
As a result, the user can search for a related document by judging the correlation of the document by the user himself / herself. If the user is searching for a related document of the electronic document A and the system diagram is as shown in FIG. 8C, the electronic document B and the electronic document X, and further the electronic document Y and the electronic document Z Relevance can be found without searching.
In consideration of visibility, it is desirable that the user can arbitrarily expand or omit the hierarchical structure. If the hierarchical structure is omitted, it is desirable that it can be easily grasped. Also, using the evaluation value of the degree of association between documents obtained in the first embodiment and the second embodiment, for example, if the evaluation value is high, the distance between documents is short, and conversely if the evaluation value is low, the distance is You may arrange | position so that it may become long.

[Fourth Embodiment]
In the first embodiment to the third embodiment, only an electronic document is used as an information source. However, as mentioned in the first embodiment, the information source is actually a Web page regardless of the electronic document. It is also possible to use paper documents, images and video data. Therefore, since there are various types of information sources, it is desirable that the type of information source can be easily grasped when the user considers following the information source.
For example, if the information source is electronic information such as an electronic document or a Web page, it can be accessed from a personal computer. However, if the information source is a paper document, it is necessary to physically acquire the paper document. In the first place, there may be no information source.
In the present embodiment, information can be color-coded according to the type of information source. Specifically, if the information source is an electronic document, it is displayed in red, blue if it is a Web page, yellow if it is a paper document, and green if it is multimedia data such as an image or video. It is possible. Of course, the types and classifications of information sources are not limited to those listed here.
Also, the colors used for color coding are not limited to those listed here. The method of color coding may be to fill each information with a corresponding color, display a color corresponding to the background of each information, or add an underline or a frame corresponding to each information. Other methods may be used.
When a link to an information source is added to the cited information and the user instructs the computer to follow the link by clicking the link, etc., the computer that received the instruction uses the appropriate program to select the information source. It is desirable to display.
As described above, the user can easily visually determine the type of the information source of the cited information, and thereby determine how to access the information source. .

Needless to say, the present invention achieves the object of the present invention by programming each function of the above-described embodiment and executing the program. In this case, the state read and executed from the recording medium realizes the functions of the above-described embodiment, and the program and the recording medium on which the program is recorded also constitute the present invention.
