뉴스와 날씨는 우리의 인간사를 둘러싸는 대단히 중요한 환경임에 틀림이 없다. 날씨에 의해 뉴스가 발생하고 또한 뉴스는 날씨를 쫓아 사회적, 경제적인 부가가치를 생성하여 우리들에게 주기도 한다. 바로 우리는 위의 두단어에 관련한 정보를 "시의적절"하게 활용하고 있을까?

주제 기반 크롤링(Topical Crawling)으로 수집된 문서들은 서로 비슷한 단어들을 가지고 있기 때문에 정작 주어진 주제에 적합하지 않은 문서 들을 포함할 수 있다. 이를 해결하기 위해 특정 주제에 해당하는 문서만을 필터링하는 작업이 필요하다. 본 논문은 화재 뉴스 기사에 대한 필터링을 위해 단어 기반 속성과 어울려 화재 뉴스 기사의 특성을 고려한 메타 데이터 속성을 추출하여 이에 특화된 기계학습 메커니즘을 제안하였다. 제안 기법의 F1-측정치는 92.1 %로서, 현재 최고의 성능을 보이는 SVM, 나이브베이즈 알고리즘보다. 2~3% 개선된 것이다.

TV뉴스 영상은 다루고 있는 대상의 범위가 넓어 뉴스의 주제를 나타냄과 동시에 그 이외의 내용도 포함한다. 또한 소재의 재이용이 가능하기 때문에 뉴스의 내용에서뿐만 아니라 영상 자체가 표현하는 내용에서도 검색이 가능해야 한다. 본 연구에서는 TV뉴스의 영상을 색인하기 위해 종래 사용되던 뉴스의 나레이션, 캡션뿐만 다니라 영상 자체를 대상으로 하여 색인어를 추출하는 방안에 대해 논하였다. 연구에서는 $\ulcorner$KBS 뉴스 9$\lrcorner$을 예로 들어 영상내용정보, 나레이션과 캡션정보, 방송정보. 촬영정보로 나누어 색인어를 부여하였다.

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.

Asia is developing rapidly in 21st century. Human and material exchanges between Korea and Asian countries have greatly increased. Korea entered the multicultural society. It became important for Korean people to understand Asia more correctively. Korean media can play a key role for this. In this point, I analyzed 1786 news contents reported in 2011 by four Korean newspapers(Chosun Ilbo, Dong-A Ilbo, Hankyoreh newspaper, Kyungh Kyunghyang Daily News), to see differences of Asia and West news aspect and its reason, focusing on news topic, amount of news, news tone and foreign media sources. In amount of news, the percent of West(54.3%) was higher than that of Asia news(45.7%). In news tone, negative news were the most in Asia news, but the least in West news. Korean newspaper showed more positive attitude to West than Asia. 1786 news were classified into seven topics(morality and justice, politics, economics and science, society, diplomacy and national defense, human interest, people). In news amount of seven topics, Korean newspapers reported hard news like morality and justice more than soft news like human interest about Asia. However they reported many soft news about West besides hard news. In news topics and tone, hard news showed negative tone most and soft news showed neutral or positive tone most. As a result, Korean news showed the negative attitude to Asia and the positive to West. Among five main sources(media, government, private organization, individual and material), only media source affected the differences of news attitude to Asia and West. Asia media source took the more positive attitude to Asia than West. West media took the negative attitude to Asia most and the neutral attitude to West most. Korean newspapers used West media as main sources in the news of all areas except East Asia. As a result, Korean newspapers showed the West-centered-attitude and reported the negative news more than neutral and positive about Asia. It was suggested that Korean newspapers had better increase Asia news in diverse spheres by the direct reporting of the correspondent and the more use of Asia media through the internet.

This study investigates the diversity of news topic and source of the New York Times, Chicago Tribune, and the Los Angeles Times in the second half of the twentieth century. In probing the conventional traits of the contemporary press, the researcher traced the changing patterns and trends of news values in terms of news-gathering routine in order to evaluate the journalistic role conception in terms of social responsibility theory. Findings indicated that the American press as a neutral transmitter has been consistently violated by source and topic bias without any significant changes during the last five decades. The data, however, revealed the evident shift of the contemporary press from the heavy reliance of official source to the business/economic source. In addition, news topics such as business, health, and education have replaced the conventional popular topics such as crime and accidents. By contrast, it was revealed that the unconventional topics such as poverty, labor and minority still fail to receive the large attention from the target papers.

Sufficient understanding of oversea construction market status is crucial to get profitability in the international construction project. Plenty of researchers have been considering the news article as a fine data source for figuring out the market condition, since the data includes market information such as political, economic, and social issue. Since the text data exists in unstructured format with huge size, various text-mining techniques were studied to reduce the unnecessary manpower, time, and cost to summarize the data. However, there are some limitations to extract the needed information from the news article because of the existence of various topics in the data. This research is aimed to overcome the problems and contribute to summarization of market status by performing topic modeling with Latent Dirichlet Allocation. With assuming that 10 topics existed in the corpus, the topics included projects for user convenience (topic-2), private supports to solve poverty problems in Africa (topic-4), and so on. By grouping the topics in the news articles, the results could improve extracting useful information and summarizing the market status.

This study explores the headlines of the metro sections posted in the major domestic news media during 1998 and 2009 and examines if the media contribute to construction of the reality. The data were systematical sampled from three main evening news programs representing each broadcasting company and the seven major nationwide newspapers (n=53,765). Results suggest the selection of news items should be influenced by the property of the regime and the trend for the time. This influence led to similarity among the news media to some extent, which are partially explained by the objectivity principle guiding the whole process of news making. Meanwhile, there was clear difference among the news media in general, and between the medium (broadcasting vs. newspaper) and within a medium, more specifically. The difference can be explained by the interaction of the property of the regime and the trend for the time and other factors including journalistic paradigm and ownership of each company.
