Abstract

This paper proposed a movie retrieval system based on sentimental keywords extracted from user's movie reviews. At first, sentimental keyword dictionary is manually constructed by applying morphological analysis to user's movie reviews, and then keyword weights in the dictionary are calculated for each movie with TF-IDF. By using these results, the proposed system classify sentimental categories of movies and rank classified movies. Without reading any movie reviews, users can retrieve movies through queries composed by sentimental keywords.

본 논문에서는 사용자가 작성한 영화평으로부터 추출한 감정어휘에 기반한 영화검색시스템을 제안한다. 먼저, 사용자의 영화평을 형태소분석하고 수작업으로 감정어휘사전을 구축한다. 그 다음, 검색의 대상이 되는 영화별로 감정어휘사전에 포함되어 있는 감정어휘들의 가중치를 TF-IDF를 이용하여 계산한다. 이러한 결과를 이용하여 제안 시스템은 영화의 감정 분류를 결정하고, 랭킹하여 사용자에게 보여주게 된다. 사용자들은 영화평을 읽지 않고도, 감정 어휘로 구성된 질의어를 입력하여 원하는 영화를 찾을 수 있게 된다.
