US 10,095,685 B2 · Phrase pair collecting apparatus and computer program therefor

Abstract

[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 DB 410 storing seed pairs each consisting of a pair of phrases including a combination of a noun and a predicate template; a semantic relation pattern DB 400 storing semantic relation patterns between words; a word pair DB 402 storing word pairs related to any of the semantic relation patterns; a semantic relation pattern matching unit 470 for determining which of the semantic relation pattern matches a noun pair in each seed pair stored in causality seed pair DB 410; and a word pair replacing unit 472 for replacing the noun pair of a seed pair using, of the word pairs stored in the word pair DB 402, 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.

Dependent claims

A phrase pair collecting apparatus for collecting hypotheses of phrase pairs based on one or more seed pairs each consisting of first and second phrases representing a cause and a result, respectively, each of said phrase pairs consisting of two phrases assumed to represent causality, each of said first and second phrases including a combination of a noun and a predicate template;

said apparatus comprising:
a storage medium configured to:
store said one or more seed pairs;
store semantic relation patterns each representing a semantic relation pattern between words;
store word pairs each related to any of the stored semantic relation patterns;
a processor configured to:
determine a semantic relation pattern that matches a noun pair consisting of the nouns in said first and second phrases in each stored seed pair, wherein the determined semantic relation pattern is related to at least one of the stored word pairs;
and
generate a new hypothesis by replacing a noun pair of a given seed pair of the one or more seed pairs with each of the stored word pairs related to the semantic relation pattern determined to be matching said noun pair;
wherein the generation of the new hypothesis improves information extraction from electronically available documents.

7 more elements

A computer program for collecting hypotheses of phrase pairs based on one or more seed pairs stored on a storage medium each consisting of first and second phrases representing a cause and a result, respectively, each of said phrase pairs consisting of two phrases assumed to represent causality, each of said first and second phrases including a combination of a noun and a predicate template, wherein the computer program is stored on a non-transitory computer readable medium and includes instructions configured to cause a processor to:

determine a semantic relation pattern that matches a noun pair consisting of the nouns in said first and second phrases in each seed pair stored on the storage medium;
and
generate a new hypothesis by replacing a noun pair of a given seed pair of the one or more seed pairs with each of word pairs stored on the storage medium related to the semantic relation pattern determined to be matching said noun pair, wherein:
semantic relation patterns are stored on the storage medium;
each of the stored word pairs are related to any of semantic relation patterns stored on the storage medium;
and
each of the stored semantic relation patterns represents a semantic relation pattern between words;
wherein the generation of the new hypothesis improves information extraction from electronically available documents.
