Abstract

Nowadays, overflowing data produced every second from the internet make people to be difficult to search for the useful information. That's why people have invented and developed unique tools that they get some relevant information. In this paper, the recommender system, one of the effective tools, is used and it helps us to get the useful information that we want by using demographic information to predict new items of interest. The demographic recommender system in this paper computes users' similarity using demographic information, age and gender. So we performed demographic analysis on movie ratings on Internet Movie Database (IMDB) web site that movies are rated by thousands of people, where users submitted a movie rating after they watched a recent popular film. Meanwhile, we can understand that user's ratings, among various determinants of box office, is very essential factor in the study on recommendation of movie. This paper is aimed at analyzing movie average ratings directly given by film viewers, categorizing them into groups by sex and age, investigating the entire group and finding the representative group by examining it with F-test and T-test. This result is used to promote and recommend for the target group only. Therefore, this study is considerably significant as presenting utilization for movie business as well as showing how to analyze demographic information on movie ratings on the web.

인터넷에서 매 순간 발생하는 데이터의 홍수는 사용자가 필요로 하는 유용한 정보를 검색하는데 어려움을 초래한다. 그래서 많은 사용자들이 자신이 원하는 정보를 쉽게 찾기 위한 기법을 고안하고 이를 지원하는 도구를 개발하게 되었다. 이런 유용한 도구 중 하나인 추천시스템은 기존의 사용자 정보를 분석하여 사용자가 원하는 제품이나 정보를 추천하는 것이다. 본 논문에서는 추천시스템을 활용하여 원하는 정보를 제안하는데 인구통계학적인 기법을 사용한다. 인구통계학 기반 추천시스템은 나이, 성별과 같은 인구통계학적인 특성을 사용하여 유용한 정보를 추출한다. 본 연구는 영화 선택 시 중요한 요소인 사용자 평점을 분석하고 이를 활용할 수 있는 방법을 제시하였다. 이를 위해 Internet Movie Database(IMDB) 웹 사이트에 있는 영화의 사용자 평점을 인구통계학적 요인으로 분석하였다. 본 논문에서는 인구통계학적 분석을 위해 사용자를 성별과 연령대로 분류하였고, 각 영화를 22개 장르로 나눈 IMDB 기준에 따라 사용자 평점을 분석하였다. 각 장르별 영화에 대해 사용자 그룹의 평균 평점을 F-테스트와 T-테스트를 수행하여 그 장르 영화 평점과 동일한 결과를 나타내는 대표 그룹을 찾아내었다. 인구통계학적 분석 결과인 대표 그룹은 새로운 영화가 개봉될 때 대표 그룹에 대한 프로모션과 추천을 통해 영화 홍보를 할 수 있는 대상을 찾아내는데 유용하다.
