[0060]
(Embodiment of document search)
In the present invention, it is desirable to classify documents in advance or according to a search condition designated by the user. Further, when displaying the list of classification results, it is desirable to summarize the contents of the document according to the search / classification conditions. In the following, first, a document summarization technique for searching and classifying documents will be described.
[0061]
FIG. 2 is a schematic diagram showing one schematic configuration of an embodiment of a summarization apparatus that summarizes documents. The summarization apparatus is realized by causing the information processing apparatus to execute a program. Hereinafter, a description will be given with reference to FIG.
[0062]
The summarizing apparatus 201 includes a morpheme string input receiving unit 202, an element storage unit 203, a template storage unit 204, an element search unit 205, and a summary generation unit 206.
[0063]
The morpheme string input reception unit 202 receives an input of a morpheme string. This morpheme sequence is a morpheme sequence of a document to be summarized.
[0064]
On the other hand, the element storage unit 203 stores in advance a morpheme string to be recognized as an element and an attribute of the element. For example, the following morpheme strings are stored in the element storage unit 203.
・ "SEGA" (attribute "distributor")
・ "Dream cast" (attribute "product")
[0065]
Furthermore, the template storage unit 204 stores a template including a stored attribute column and character string information embedded between the attribute columns. For example, the following template is stored in the template storage unit 204.
“The“ Seller ”released the“ Product ”.”
[0066]
The double brackets correspond to the element attributes, and “GA” and “released” correspond to the character string information embedded.
[0067]
Then, the element search unit 205 searches for the stored element from the morpheme string that has been accepted as input, and outputs the element of the search result as a string.
[0068]
For example, consider the case where the following morpheme string is input. Each morpheme is separated by “/”.
"Sega / GA / New / I / Game machine // Release /// Announcement / Shi / Ta /./ Game machine / Name / ha /" / Dreamcast / "/. /Ha/100/10,000/unit/to/expected/n/de/i/ru/./]
[0069]
Then, the element search unit 205 outputs the following element sequence.
"Sega" (distributor), "Dreamcast" (product)
[0070]
Note that the morpheme strings that are the elements in the brackets correspond to the attributes of the elements in the parentheses.
[0071]
On the other hand, the summary generation unit 206 obtains the attribute column of the element from the element column of the search result, and uses the stored attribute including the attribute column of the element from the stored template. A summary is generated by embedding character string information included in the template between morpheme strings corresponding to elements corresponding to each of the columns.
[0072]
This produces the following summary:
“Sega released Dreamcast.”
[0073]
In the conventional technique, information that spans a plurality of sentences cannot be summarized. In this way, in this technique, information in a document can be summarized across a plurality of sentences.
[0074]
In addition, the summarization apparatus 201 further includes a sentence input reception unit 211 and a morpheme analysis unit 212.
[0075]
Here, the sentence input receiving unit 211 receives input of one or more sentences. On the other hand, the morpheme analysis unit 212 performs morpheme analysis on the sentence that has received the input, and outputs a morpheme string that is the analysis result.
[0076]
Furthermore, the morpheme string input reception unit 202 receives the output morpheme string as an input.
[0077]
With these functions, even if the following document information is given, it can be automatically converted into a morpheme sequence in the summarizing apparatus 201 and processed.
“Sega has announced the launch of a new game console. The game console is called“ Dreamcast ”. Expected to ship 1 million units this year.”
[0078]
The summary device 201 further includes a summary extraction unit 221.
[0079]
The summary extraction unit 221 extracts a sentence including a column of search result elements from one or more sentences accepted as input, and outputs this as a summary.
[0080]
In the above example, the following two sentences are extracted summaries.
“Sega has announced the launch of a new game console. The name of the game console is“ Dreamcast. ”
[0081]
The summarization apparatus 201 further includes a designated input receiving unit 231 and an output unit 232, and can be configured as follows.
[0082]
That is, the designation input receiving unit 231 receives a summary method designation input.
[0083]
On the other hand, the output unit 232 outputs the summary generated by the summary generation unit 206 when the specification of the summary method that has received the input is the first method, and the summary extraction unit 221 when the input is the second method. Output the summary extracted by.
[0084]
This allows the user to select a summary technique.
[0085]
The summarizing apparatus 201 further includes an attribute input receiving unit 241 and can be configured as follows.
[0086]
That is, the attribute input receiving unit 241 receives input of attributes of elements to be summarized.
[0087]
On the other hand, the element search unit 205 searches for a morpheme string having an attribute of an element for which an input has been accepted.
[0088]
Further, the summary generation unit 206 uses a stored template that further includes an attribute of an element that has received an input.
[0089]
In addition, the summary extraction unit 221 also extracts a sentence including the attribute element.
[0090]
A large number of elements, morphemes, and templates are prepared in advance, a template to be used is selected by the user's designation, and a morpheme string of elements having attributes designated by the user is acquired and summarized.
[0091]
As a result, the user can specify the attribute of the desired element as appropriate.
[0092]
In addition to the elements stored in the element storage unit 203 as described above, morpheme strings corresponding to “price”, “time”, “date”, “place name”, and the like may be recognized as elements. These are called “individual names”. In the above input example, “within the year” (time), “1 million units” (number), etc. are the individual names.
[0093]
In this way, documents can be summarized based on element attributes. Further, it is possible to classify documents for each attribute based on elements.
[0094]
(Embodiment of the Invention)
FIG. 3 is a schematic diagram showing one schematic configuration of the embodiment of the document display device of the present invention. The document display device is realized by causing the information processing device to execute a program. Hereinafter, a description will be given with reference to FIG.

On the other hand, the storage unit 303 stores words and their attributes in association with each other. Thereby, the attribute of the phrase contained in the document can be obtained. In the summarizing apparatus 201, “morpheme string” corresponds to “word” and “element attribute” corresponds to “attribute”. Therefore, the element storage unit 203 of the summarizing apparatus 201 and the storage unit 303 can be shared.
[0098]
Furthermore, the setting unit 304 sets a link relationship between a certain attribute and another attribute for the stored attribute.
[0099]
For setting the link relation, a designation dialog shown in FIGS. 4 to 6 is used.
[0100]
In the designation dialog shown in FIG. 4, a unidirectional link relationship can be set. In the link source dialog list, attributes of “product name”, “organization name”, “region name”, “natural name”, “facility name”, and “person name” are displayed. Here, “organization name” is highlighted, which means that the link source of the link relationship is “organization name”.
[0101]
On the other hand, in the link destination list, “person name” and “product name” are displayed as attributes for which a link relationship has already been set. That is, “organization name → person name” “organization name → product name” is set as the link relationship.
[0102]
In the available list, attributes for which a link relationship has not yet been set are displayed.
[0103]
If there is something to be added as a link destination in the available list, the user clicks the attribute with the mouse 106 to select it, and clicks the add button. Then, the display of the attribute moves to the linked list.

In the designation dialog shown in FIG. 5, a bidirectional link relationship can be set. If an attribute to be linked in the link list is selected by clicking with the mouse 106 in the link list, the attribute is linked in both directions.
[0107]
In the figure, “product name”, “organization name” and “person name” are selected, so “product name → organization name” “product name → person name” “organization name → product name” “organization name → person name”. Six types of link relationships of “person name → product name” and “person name → organization name” are set.
[0108]
In the designation dialog shown in FIG. 6, a multilink relationship can be set. In the linked list, the region name is the first attribute, the organization name is the second attribute, the person name or product name is the third attribute, and the fourth attribute is “Organization name if the third is a person name” "" If the third is the product name "is displayed, and" the product name if the fourth is the organization name "is displayed as the fifth attribute, and these tree-like link relationships are set. be able to.
[0109]
In this way, the link relationship can be set using various designation dialogs, and a predetermined link relationship may be set.
[0110]
Then, the extraction unit 305 is a word / phrase in which the word / phrase is stored among the words / phrases included in the document for each of the documents included in the document group in which the input is accepted, and the link relation is set in the attribute of the word / phrase. Extract what you have.
[0111]
On the other hand, the illustration unit 306 illustrates the extracted word / phrase by the link relationship of the attribute of the word / phrase.
[0112]
At this time, if the link relationship set by the user is configured in a tree shape, in addition to the tree shape illustrated in FIG. 7, for example, a tree shape illustrated in Windows Explorer is used. The words and phrases can be illustrated as nodes, and arrows can be drawn between the nodes of the words and phrases having a link relationship.
[0113]
On the other hand, when the link relationship set by the user is configured in a network form (that is, when a strongly connected component exists in a directed graph in which the link is a directed arc and the phrase is a node), the illustrated state is also a network form. Become. FIG. 8 shows an example of a network diagram in the illustrated unit 306.
[0114]
Further, if the number of documents including the word / phrase is illustrated as additional information in the vicinity of each word / phrase node (not shown in FIG. 8), the user presents additional information for obtaining a desired document. Can do.
[0115]
Furthermore, the selection unit 307 receives an instruction input for selecting the illustrated word / phrase. For the selection of a phrase, a technique of clicking the phrase with the mouse 106 is used.
[0116]
Then, the display unit 308 displays a document including the selected word / phrase among the plurality of documents that have been input.
[0117]
In this case, if a list is displayed using the contents of the documents summarized by the summarization apparatus 201, a list of documents according to the user's interest can be easily created.
[0118]
In addition, the display unit 306 also displays the number of documents including both words of the node in the vicinity of the arrow of the link relationship between the nodes. The selection unit 307 can be configured assuming that a node has been selected.
[0119]
The selection unit 307 can select a plurality of words by clicking on the words with the mouse 106 while pressing the control key of the keyboard 105. When a plurality of words / phrases are selected, the display unit 308 displays a document including all the words / phrases.
[0120]
