Abstract: Provided is a text processing system which, when an attribute corresponding to one tabulation axis is set, is capable of generating a text group which will produce non-obvious tabulation results when cross-tabulation is performed using that attribute. At the time of input of respective attribute values of an attribute which corresponds to a tabulation axis in cross tabulation and a document associated with any one of the attribute values of the attribute, text extraction means 71 extracts portion not including the attribute value of the attribute from each text obtained by dividing the document into predetermined units. Group generation means 72 performs entailment recognition between texts on the extracted texts and groups texts having an entailment relation.

Abstract: A text visualization system allows a user to ascertain a relationship of viewpoints between categories in clustering of documents including texts of a plurality of categories. Each of a plurality of documents includes texts of each of a plurality of categories. A text and an element text that entails the text among texts included in the plurality of documents are set with respect to each of the categories. A text display displays a plurality of texts of each of one or more categories among the plurality of categories. The text display, in response to receiving a designation of a text of a specific category by a reception unit, extracts, from a plurality of texts of another category, a text that entails an element text of the another category included in a document including an element text that entails the text of the specific category, and displays the extracted text.

Abstract: A text visualization system which allows a user to efficiently ascertain a result of clustering of texts is provided. A clustering system (1) includes a representative text display unit (51), a reception unit (55), and an element text display unit (52). The clustering system (1) is accessibly connected to a storage that stores a plurality of texts and information indicating a representative text and an element text that entails the representative text among the plurality of texts. The representative text display unit (51) displays a plurality of representative texts. The reception unit (55) receives a designation of a specific representative text among the plurality of representative texts. The element text display unit (52) extracts, in response to receiving the designation of the specific representative text, an element text that entails the designated specific representative text from the plurality of texts, and displays the extracted element text.

Abstract: A similar sentence set generation unit 81 groups sentences representing a same concept or event from a set of analysis target sentences, to generate a similar sentence set. A similar sentence set extraction unit 82 extracts, using one or more specific sentence extractors each capable of extracting a specific sentence belonging to a specific classification from the set of analysis target sentences, one or more sentences not extracted by any of the specific sentence extractors from among the sentences belonging to the similar sentence set, as an exclusion similar sentence set.

Abstract: Provided is a text processing system capable of classifying a plurality of texts into groups whose overviews are able to be grasped and classifying texts semantically having entailment relation into the same group even if the texts are not determined to have the entailment relation. Entailment recognition means 71 performs entailment recognition between texts on given texts. Group generation means 72 selects an individual text and generates a group including texts entailing the selected text as members. Group integration means 73 integrates groups in the case where groups satisfy a predetermined condition based on the degree of overlap of members between groups.

Abstract: A search system includes a reception unit 601 for receiving specification of a specific sentence in an article, a search unit 602 using a first sentence being the specified sentence as a search query to search an article including a sentence having a meaning similar to the connotations of the first sentence, and a display unit 603 for displaying information of the searched article as a related article to the first sentence, and when there are a plurality of related articles, the display unit 603 preferentially displays the related articles in descending order of difference relative to a first article being the article including the first sentence.
