20100017391 | POLARITY ESTIMATION SYSTEM, INFORMATION DELIVERY SYSTEM, POLARITY ESTIMATION METHOD, POLARITY ESTIMATION PROGRAM AND EVALUATION POLARITY ESTIMATIOM PROGRAM - An evaluation polarity of reputation information with an unknown evaluation polarity is estimated by utilizing reputation information with a known evaluation polarity. The present polarity estimation system is a polarity estimation system for estimating an evaluation polarity indicating whether reputation information is positive or negative, and includes a reputation information storage part that precedently stores reputation information with a known evaluation polarity; and a polarity estimating means for estimating an evaluation polarity of reputation information with an unknown evaluation polarity on the basis of the reputation information with the known evaluation polarity precedently stored in the reputation information storage part. | 01-21-2010 |
20100318525 | ATTRIBUTE EXTRACTION METHOD, SYSTEM, AND PROGRAM - Sets of strings of which the drawing positions are arranged in one direction are extracted from a document as attribute groups. An attribute name score is calculated for each attribute group to determine an extent to which each attribute group is a set of attribute names. Based on the attribute name scores, an attribute name group is selected out of the attribute groups. From among the attribute groups, an attribute group which includes a string which is the same as at least one string of the attribute name group and of which the drawing position is the same as that of the string of the attribute name group is selected. From the string at the same drawing position, an attribute name is extracted. From the other strings of the selected attribute group than those at the same drawing position, an attribute value corresponding to the attribute name is extracted. | 12-16-2010 |
20110029303 | WORD CLASSIFICATION SYSTEM, METHOD, AND PROGRAM - A word classification system is provided with an inter-word pattern learning section for learning at least either the context information or the layout information between classification-known words which co-appear and creating an inter-word pattern for determining whether data relating to a word pair which is a combination of words is data relating to a same-classification word pair which is the combination of words in the same classification or data relating to a different-classification word pair which is a combination of words in different classifications on the basis of the relationship between the classification-known words which co-appear in a document. | 02-03-2011 |
20110055228 | COOCCURRENCE DICTIONARY CREATING SYSTEM, SCORING SYSTEM, COOCCURRENCE DICTIONARY CREATING METHOD, SCORING METHOD, AND PROGRAM THEREOF - A cooccurrence dictionary creating system includes: a language analyzing section which subjects a text to a morpheme analysis, a clause specification, and a modification relationship analysis between clauses, a cooccurrence relationship collecting section which collects cooccurrences of nouns in each clause of the text, modification relationships of nouns and declinable words, and modification relationships between declinable words as cooccurrence relationships, a cooccurrence score calculating section which calculates a cooccurrence score of the cooccurrence relationship based on a frequency of the collected cooccurrence relationship, and a cooccurrence dictionary storage section which stores a cooccurrence dictionary in which a correspondence between the calculated cooccurrence score and the cooccurrence relationship is described. | 03-03-2011 |
20110161144 | INFORMATION EXTRACTION SYSTEM, INFORMATION EXTRACTION METHOD, INFORMATION EXTRACTION PROGRAM, AND INFORMATION SERVICE SYSTEM - According to the present invention, phrases of the same kind can be extracted from a plurality of documents having various formats. A storage device stores a plurality of documents that have various formats. A pattern candidate creating unit receives a list of input words that are selected as samples among phrases that are to be included in a dictionary. The pattern candidate creating unit selects one document, determines forward and backward character strings of input words in the selected document as candidates of patterns, and stores the forward and backward character strings as a pattern candidate. The pattern candidate creating unit executes the above processes for each of the documents. A phrase candidate creating unit extracts phrases interposed between patterns included in the pattern candidate as candidates of phrases to be output, and stores the extracted phrases as a phrase candidate. A phrase selecting unit outputs a candidate of a phrase satisfying a predetermined condition among candidates of phrases included in the phrase candidate as an output word to an output device. | 06-30-2011 |
