This study analysed news consumers' perception toward the use of mobile devices and examined their preference on news contents. News audience in the mobile age hoped that news producers make news contents through communication with audience. They showed a negative stance against the attitude that news producers underestimate the audience' intellectual level. Audience preferred novel news formats and services adapted to the mobile environments. In terms of the role of the press, they preferred interpretive and investigative journalism rather than superficial and sensual journalism. Therefore, news companies should consider audience' news consuming attitudes in their producing and delivering news. They also should seek for utilizing the use of the mobile media more aggressively than ever before.

This paper examined how the millennial generation consumes mobile news through social networking sites with regards to user patterns, preference topics and news values, and whether news topics and news values may influence their overall mobile SNS news consumption and interactivity. The findings show that more than 2/3 of respondents consumed mobile SNS news at least once everyday for 30minutes to one-hour. Male millennials tended to use Facebook and Kakao-talk more than female. While the portal site was the most accessed channel for consuming mobile news, SNS was the second, more than the combined use of national daily papers, TV, and internet newspapers. The respondents' demographic characteristics and news topics also affect the form and degree of news interactivity. With regards to their preferences and prioritization of news values, millennials tend to perceive 'impact' and 'usefulness' as being most important, despite the differences of their demographic characteristics. They also preferred those news values most. There were significant differences in terms of preferred news topics according to the demographics' characteristics.

Mobile news users want news articles without advertising, meanwhile the news providers require advertisement displays in several types to attain advertising revenue. In this paper, we classified the types of advertisements on mobile news articles into fixed article type which is fixed on some areas of articles, fixed screen type which is fixed on mobile screens, and a combination type of them. In addition, we proposed a smart solution based on overlapping method which effectively organize advertisements to not distract the readers. The proposed method is similar to fixed article type and overlapping technique of advertisements on news article's photo or virtual area. The performance evaluation result shows that the proposed method provides more spaces for news articles effectively than the existing methods. Although only some areas of advertisements may be blocked according to the number or size of advertisements, the effect is not critical.

최근 Device 의 대중화로 모바일 폰 사용자는 언제 어디서라도 정보서비스 및 멀티미디어 동영상 서비스를 쉽게 접할 수 있게 되었다. 하지만, 작은 화면과 불편한 User Interface 를 가진 모바일 Device 의 한계와 양적인 컨텐츠의 증가로 인하여 사용자가 원하는 정보를 Access 하기에는 너무 많은 시간과 비용이 소요되고 있다. 본 논문에서는 사용자의 Accessibility 욕구를 충족하고 시간과 비용을 절감하기 위한 방법으로서 무선 인터넷 환경에서의 추천 시스템을 기반으로 방대한 분량의 뉴스 컨텐츠 가운데 개인화 된 뉴스를 선별, 제공해 주는 지능형 추천 시스템을 설계 구현하고자 한다. 본 논문은 인공 지능 분야 중 에이전트의 추천 역할과 기능면에서 Collaborative Filtering 방법이 갖고 있는 계산 속도 문제에 대한 대안으로서, 유사한 선호도의 사용자를 특성에 따라 분류하기 위해 군집분석을 이용했으며, 각 군집별로 뉴스 카테고리를 Weighting 한 후, 뉴스 컨텐츠를 Scoring, Listing하여 사용자가 읽은 뉴스에 대한 평가를 기록하고 이틀 각 군집별로 반영하는 방법을 수행하였다. 추가로 뉴스 컨텐츠의 사용자 만족도를 평가하기 위하여 뉴스를 처음부터 끝까지 읽은 완독률을 측정기준으로 제시하고 일반적인 무선 인터넷 환경하의 뉴스 메뉴체계와 비교하여 설계된 시스템의 성능에 대한 유효성을 검증하였다.
