최근 들어, 영화에 대한 많은 추천시스템이 제안 되고 있는데, 나이와 장르, 성별에 관한 협업필터링 추천 방식을 주로 사용했다. 협업필터링 방법에 좀 더 정확한 추천을 하기 위해서 본 논문에서는 기존의 협업필터링 방식에 더해서 사용자의 리뷰에서 인간의 '감정'을 장르에 편입시켜 좀 더 사용자에게 정확하고 명확하게 추천하는 영화추천시스템을 제안한다.

최근 많은 추천 시스템들이 연구 되고 있으며, 사용자들에게 의사결정을 도와주는 추천시스템에 대한 중요도가 급증하고 있다. 기존의 영화 추천시스템에서는 희박성의 문제가 제기된다. 본 논문에서는 이러한 문제를 보완하고자 사용자가 영화에 대해 남긴 리뷰로부터 영화키워드를 분석하고 분석된 키워드로부터 가중치를 활용한다. 즉 사용자들로부터 영화에 대한 리뷰를 수집하고 리뷰로부터 각 영화 키워드를 분석해 키워드별 가중치를 활용해 이를 기반으로 영화를 추천한다. 그 결과 사용자에게 만족할만한 정보를 제공해 효율성을 높이고, 영화에 대한 개인 리뷰를 반영한 영화추천 시스템을 설계 및 구현해 사용자에게 적절한 영화를 추천한다.

본 연구에서는 감성 분석 기반의 키워드 도출형 영화 리뷰 웹사이트를 개발하였다. 사용자들은 영화에 대한 리뷰를 작성할 때, 자동으로 키워드를 추출하는 기능을 활용하여 다양하면서도 빠르게 정보를 얻을 수 있다. 사용자가 작성한 리뷰를 시스템에 입력하면, 내부적으로 ChatGPT를 활용하여 텍스트를 분석하고 키워드를 추출한다. 이를 통해 사용자는 별다른 노력 없이도 키워드를 통해 영화의 장르, 감독, 배우, 플롯 요소 등 다양한 정보를 빠르게 확인할 수 있다. 추출된 키워드는 저장되어 시각화에 활용되며, 사용자들은 리뷰에 대한 원하는 정보를 쉽게 얻을 수 있다. 개발된 키워드 도출형 영화 리뷰 웹사이트는 사용자들에게 빠르고 다양한 정보를 제공하며, 영화 관련 결정을 내리는 데에 도움을 줄 것으로 기대된다.

This study examines demand of the Korean TV VOD using monthly aggregate data and time series analysis models. In particular, the impact of box office attendance, number of IPTV subscribers, income and price of substitutes on TV VOD market is analyzed. Data on TV VOD download during the period 2013 January to 2018 June are used for the empirical analysis. TV VOD demand shows lower level of seasonality than box office attendance and the share of monthly top1 movie in TV VOD platform is also lower than that of box office attendance. The relationship between a movie's holdback and box office performance does not seem consistent. The empirical result of ARDL model reveals that in the short-run box office attendance, number of IPTV subscribers and price of substitutes have significant impact on TV VOD demand. The result on the long-term relation shows that income is the only determinant of TV VOD demand. The impact of box office attendance on TV VOD is not shown to be robust both for the short-term and long-term.

The purpose of this paper is to analyze the impact of distributors on the movie exhibition by distributor types. For the analysis, the concept 'screen elasticity of box office' is adopted. Using the weekly screening data of 94 hit movies released in Korea in 2014 and 2015, the panel analysis estimates the 'screen elasticity of box office' with the Hausman-Taylor estimator. The results show that the screen elasticity of box office is smaller for vertically integrated distributors(CJ E&M and Lotte Entertainment) and Hollywood distributors than the local distributors(Showbox and NEW) that do not own integrated cinemas. This means that exhibitors allocate a larger number of screens to vertically integrated distributors and Hollywood distributors. As the two distributor groups had higher market share during the period, the results imply that the screen elasticity is related to the market performance of distributors. Smaller screen elasticity of the vertically integrated distributors might be related not to the ownership to theaters but to higher market share of the distributors.

This thesis discussed the status of women workers as wage laborers and home laborers and the valid of a documentary movie for representing women laborers through a documentary movie, Weabak that revolved around Home-ever occupation strike leaded E-Land labor union at 30th June, 2007. Jobs for women labors got covered by the flow of flexibility with the policy of labor flexibility in South Korea during 1990s. The reasons that justify this trend are their position in the households, and their roles in working places are not very important because there are not required difficult skills. The mass dismissal which caused the E-Land strike also shared these ideologies. In Weabak, since women laborers were always expected to care for their family, they were need strikes in their home as well as their working place. However, a household is a basement for them to get the identity as a women laborer. It has two ambivalent meanings, as a protected area and disorder for them to pursue their life at the same time. Identity of Women laborers, domestic laborers as well as wage laborers, are very difficult to identify as a general noun, a laborer. Weabak is an important example to show us the possibility of a documentary as searching new realism for representing women laborers' story using their own perspective.

This study tried to explore the contents of film critics' reviews reported in the press. Based on fifty nine Korean movies with over 100,000 audience in 2017, this study collected 1113 reviews from fifty five movies with the exception of four without reviews. This study focused on the correlation between film's overall quality and four evaluation items such as directing, acting, story, and the visual. Examining the difference in the report timing of the review, the length of the review, and the intensity of the opinion, this study also analyzed the relationship between the internal aspects of reviews and box office performance. According to the results, the valence of critics' reviews was generally positive. Looking at the difference of reporting time, this valence was higher in the week before release than in the release week of film. The evaluation items of reviews were highly covered both before movie release and in the opening week. These were significantly declined in the second week of release. In the relationship between the number of reviews by each movie and box office performance, a positive correlation was found.

Recently, generative models based on the Transformer architecture, such as ChatGPT, have been gaining significant attention. The Transformer architecture has been applied to various neural network models, including Google's BERT(Bidirectional Encoder Representations from Transformers) sentence generation model. In this paper, a method is proposed to create a text binary classification model for determining whether a comment on Korean movie review is positive or negative. To accomplish this, a pre-trained multilingual BERT sentence generation model is fine-tuned and transfer learned using a new Korean training dataset. To achieve this, a pre-trained BERT-Base model for multilingual sentence generation with 104 languages, 12 layers, 768 hidden, 12 attention heads, and 110M parameters is used. To change the pre-trained BERT-Base model into a text classification model, the input and output layers were fine-tuned, resulting in the creation of a new model with 178 million parameters. Using the fine-tuned model, with a maximum word count of 128, a batch size of 16, and 5 epochs, transfer learning is conducted with 10,000 training data and 5,000 testing data. A text sentiment binary classification model for Korean movie review with an accuracy of 0.9582, a loss of 0.1177, and an F1 score of 0.81 has been created. As a result of performing transfer learning with a dataset five times larger, a model with an accuracy of 0.9562, a loss of 0.1202, and an F1 score of 0.86 has been generated.

Most of the existing studies on the volume and valence of the eWOM (electronic word of mouth) about movies and box-office revenues were conducted using online actual data (secondary data) at Yahoo Movies, IMDB.com, Naver Movies, etc. However, it is difficult to grasp psychological variables from online actual data. Therefore, existing studies using online actual data could not identify the causal relationship among volume, valence and psychological variables. This study fills this gap in the literature. This study aims to examine the direct and indirect effects (i.e. mediating effect) of the volume and valence of online reviews about movies on purchase intention through review credibility as a mediator. We conducted a survey on the South Korean consumers and a structural equation modeling. The outcomes show that the total effects of both volume and valence are significant. In addition, volume has an indirect effect only (i.e. full mediating effect) on purchase intention through review credibility, but valence has both direct and indirect effects (i.e. partial mediating effect) on purchase intention through review credibility. The theoretical and practical implications for these results are presented.
