摘要:
Described are a reputation analysis device, reputation analysis method, and reputation analysis-use program capable of suitably analyzing temporal changes in reputation for an object indicated by a keyword. The disclosed reputation analysis device is provided with a voluntary activity description extraction means for extracting descriptions representing voluntary activity related to an object indicated by a keyword that has been input from within a plurality of documents; and a reputation chronological data estimation means for counting the number of occurrences of voluntary activity at each time point wherein the voluntary activity expressed by a description representing the voluntary activity related to the object has been performed, and estimating reputation chronological data for chronologically representing evaluations for the object by the agents of the voluntary activity.

Disclosed are a text mining method, device, and program capable of performing text mining with a specific topic as an object with high precision. An element identification unit calculates a feature degree, which is an index for indicating a degree that within a text set of interest, which is a set of text that is to be analyzed, an element of the text appears. An output unit identifies distinctive elements within the text set of interest on the basis of the calculated feature degree and outputs the identified elements. The element identification unit corrects the feature degree on the basis of a topic relatedness degree, which is a value indicating a degree related to a topic of analysis, which is a topic for which each text portion of the text being analyzed has been partitioned into predetermined units that are to be analyzed.

Disclosed is an information estimation device for estimating an appropriate issue time from a time representation described in a document without intervention of any operator; wherein an information estimation device (1) which is a device for estimating an issue time of a document to be estimated, includes a candidate generation unit (11) which extracts a time representation described in the document, and on the basis of the extracted time representation, generates a plurality of possible issue time candidates having possibilities corresponding to the issue time of the document; and an issue time estimation unit (12) for obtaining a temporal proximity, for each of the plurality of issue time candidates, between the issue time candidate and other issue time candidates, and on the basis of the obtained temporal proximity, estimating the issue time of the document.

Provided is a text mining device that performs an analysis properly with respect to a difference between plural related document data. Equipped are an element extracting section 140 that extracts language elements from related two or more document data respectively; a differential processing section 150 that extracts a difference between the document data by comparing the elements between the document data which were extracted by the element extracting means 140; and a statistical processing section 170 that performs statistical processing on the difference extracted by the differential processing section 150. The differential processing section 150 has: element associating section 151 that associates respective elements which are in identical, similar, synonymous, or analogous relation by comparing the elements of the document data between the document data which were extracted by the element extracting section 140; and differential element extracting section 152 that extracts an element with no corresponding element of a pair in the association by the element association section 151.
摘要:
A document analysis device (1) comprises a common assessment information selection unit (90) and an event impact analysis unit (100). The common assessment information selection unit (90) identifies information that matches second assessment information that appears in event-related documents which include descriptions concerning a designated specific event, from among first assessment information that appears in documents for analysis which include descriptions relating to items for analysis, and classifies the information thus identified as common assessment information. The event impact analysis unit (100) counts the number of times the common assessment information appears in the documents that are generated prior to the event occurring, and the number of times the common assessment information appears in the documents for analysis that are generated subsequent to the event occurring, and derives an index that denotes the impact of the specific event upon the documents for analysis, on the basis of the results of the counts thereupon.

摘要:
The text mining device 300 includes a clustering section 301. The clustering section 301 performs clustering on a plurality of characteristic expressions extracted from a document set such that characteristic expressions, in which sentences to be referred to as original sentences are the same, are compiled in one cluster, based on the similarity in original document sets which are sets of documents including the respective characteristic expressions, the documents being of the document set. Consequently, the probability of repeatedly viewing the same original document by a user can be reduced reliably.
摘要:
Provided are a related expression generation section that accepts an evaluation object expression, an linguistic expression to be evaluated, as input and generates a linguistic expression related to the evaluation object expression as a related expression; and a credibility calculation section that acquires the evaluation object expression and the related expression from a plurality of electronic documents along with time information and calculates credibility concerning the meaning of the evaluation object expression at a specific point in time by comparing the number of times that the acquired evaluation object expression appears and the number of times that the acquired related expression appears at the same time point.
