摘要

PURPOSE: A system for detecting a related topic and a competition topic based on a topic template and an association word, a detection method thereof, and a detection device thereof are provided to automatically search, compare, and display the related topic for a specific topic and the competition topic, thereby accurately analyzing the specific analysis. CONSTITUTION: A language analysis unit(102) performs language analysis which includes morpheme analysis and entity name recognition. A topic template extraction unit(104) generates the topic template by using a language analysis result and stores the topic template in a topic template database(10). A topic ranking unit(106) measures generation frequency, topic significance, and topic reliability for topics stored in the topic template. An association extraction unit(108) measures relevance among keywords. The association extraction unit extracts an association word corresponding to the relevance and stores the same in an association database(20).
