[Object] An object of the present invention is to provide a system for collecting elements as a basis for generating a social scenario useful for people to make well-balanced good decision. [Solution] A scenario generating apparatus includes: a causality phrase pair DBstoring causality phrase pairs; synonimity generatorsand, searching, for each of the causality phrase pairs, causality phrase pairs having a cause phrase with causal consistency with the result phrase of the causality phrase pair, and generating join information for joining causality phrase pairs; join relation DBstoring the join information; and a causality joining unitjoining, to a result phrase of a causality phrase pair, a causality phrase pair having a cause phrase with causal consistency with the phrase by using the join information, and thereby linking causality. A join relation generatorthat finds a hidden relation between phrases and linking causality phrase pairs may be provided.

Scenario generating apparatus and computer program therefor

A system for collecting elements as a basis for generating a social scenario useful to make a well-balanced good decision. A complex predicate template collecting apparatus includes: a simple predicate template DB storing simple predicate templates having positive or negative polarity values added; an object noun dictionary; a complex predicate template candidate extractor extracting complex predicate template candidates each formed of a combination of a word specified by the object noun dictionary and a simple predicate template, from a WEB archive; a sahen-noun polarity adder, a quantifier noun polarity adder and a trouble-noun polarity adder, determining polarity of a noun in each of the complex predicate template candidate; and a complex predicate template polarity calculator calculating polarity of a complex predicate template candidate by a combination of the polarity of the noun and the polarity of the simple predicate template included in the complex predicate template.

[Object] An object of the present invention is to provide a system for collecting elements as a basis for generating a social scenario useful to make well-balanced good decision. [Solution] A phrase pair collecting apparatus includes: a causality seed pair DBstoring seed pairs each consisting of a pair of phrases including a combination of a noun and a predicate template; a semantic relation pattern DBstoring semantic relation patterns between words; a word pair DBstoring word pairs related to any of the semantic relation patterns; a semantic relation pattern matching unitfor determining which of the semantic relation pattern matches a noun pair in each seed pair stored in causality seed pair DB; and a word pair replacing unitfor replacing the noun pair of a seed pair using, of the word pairs stored in the word pair DB, each of those word pairs which are related to the semantic relation pattern determined to be matching the noun pair, and thereby generating new hypotheses.
