摘要:
A system and method for detecting preference expressions indicating evaluators' likes and dislikes of a product from evaluations of the product and stores text describing evaluation of the product in association with an attribute of the text. The method extracts an evaluating expression describing evaluation of the specific object from each of the texts, determines whether the extracted evaluating expression has positive or negative polarity, where the positive indicates favorable evaluation and the negative indicates unfavorable evaluation. The system inputs a text attribute that is designated as an object for detecting the preference expression and detects an evaluating expression, which is detected from a text having an input attribute from the extracted evaluating expressions as one of the preference expressions and outputs the preference expressions in association with a frequency of the preference expressions being determined to have the positive or negative polarity in the text having the attribute.
摘要:
A system, method, and program product to correctly detect a preference expression indicating persons' likes and dislikes of a commercial product or the like. Specifically, the expression detecting system for detecting preference expressions indicating evaluators' likes and dislikes of a specific object from texts describing evaluation of the specific object, and stores each of the texts describing evaluation of a specific object in association with an attribute of the text. The method extracts an evaluating expression describing evaluation of the specific object from each of the texts; determines whether the extracted evaluating expression has positive polarity or negative polarity, where the positive polarity indicates favorable evaluation of the specific object and the negative polarity indicates unfavorable evaluation of the specific object. The system then inputs a text attribute that is designated as an object for detecting the preference expressions; and detects an evaluating expression, which is detected from a text having an input attribute from the extracted evaluating expressions as one of the preference expressions and outputs the preference expressions in association with a frequency of the preference expressions being determined to have the positive polarity or the negative polarity in the text having the attribute.
摘要:
A system, a method, and a program for selecting advertisements for displaying advertisements associated with content when the content is sent via communication means such as the Internet. Providing suppression of the appearance of an advertisement on the internet when one role label, “Victimizer”, “Victim” or “Beneficiary” is systematically assigned to a corresponding thing referred to in the article: a company, a person, or a product. The advertisement selection mechanism controls suppression of the appearance of advertisements associated with such role labels and can calculate the affinity or linkage between an article and the advertisement as a value. The suppression of the advertisement occurs by subtracting the value of the affinity. The degree of suppression by role labels is preferentially decreased over time.

A computer implemented method, system, and product for finding correspondence between terms in two different languages. The method includes the steps of: creating a technical term set and a general term set for each of i) a first language and ii) a second language, creating two bipartite graphs, where each graph corresponds to one of the two languages, and connects the technical term set and general term set of each language, respectively, with weighted links based on corpus information, creating a third bipartite graph by creating weighted links between general terms in the first language and general terms in the second language by using a translation dictionary, creating an association matrix M corresponding to the three bipartite graphs, calculating a similarity matrix Q by calculation of an inverse matrix, and outputting correspondence between the technical term sets of the first and second language on basis of the similarity matrix.
