Abstract

Through opinion mining, we can analyze the degree of positive or negative sentiments that customers feel about important entities or attributes in online customer reviews. But, the limit of the opinion mining techniques is to provide only simple functions in analyzing the reviews. In this paper, we proposed novel techniques that can analyze the online customer reviews multi-dimensionally. The novel technique is to modify the existing OLAP techniques so that they can be applied to text data. The novel technique, that is, multi-dimensional analytic model consists of noun, adjective and document axes which are converted into four relational tables in relational database. The multi-dimensional analysis model would be new framework which can converge the existing opinion mining, information summarization and clustering algorithms. In this paper, we implemented the multi-dimensional analysis model and algorithms. we recognized that the system would enable us to analyze the online customer reviews more complexly.

오피니언마이닝 기법은 대량의 고개리뷰들에 나타나는 핵심개체 또는 속성들에 대하여 고객들이 느끼는 긍정 또는 부정의 정도를 계산할 수 있지만, 그 분석능력이 단순하다는 한계가 있다. 본 논문에서는 온라인 고객리뷰들에 대하여 다차원적으로 분석할 수 있는 기법을 제안하였다. 기존의 OLAP기법을 텍스트 데이터형에 적용할 수 있도록 수정하였다. 다차원 분석모델은 명사축과 형용사축, 문서축으로 구성되는 3차원 공간 개념을 4개의 관계형 테이블로 실체화 한 것이다. 다차원 분석모델은 기존의 오피니언마이닝, 정보요약, 클러스터링 알고리즘들을 융합할 수 있는 새로운 틀이라는 점에서 그 가치가 있다. 본 논문에서 제안한 다차원 분석모델과 알고리즘들을 실제로 구현하여 온라인 고객리뷰에 대한 복잡한 분석을 수행할 수 있음을 확인하였다.
