In order to support new construction engineering companies with weak information power to successfully advance into the overseas construction market, this study tried to analyze what are the keywords of interest in the overseas construction market and how they differ from Korea. For this purpose, we recently collected 2,473 news article titles and major articles targeting smart cities that are of high interest in Korea and Vietnam. Through network configuration and topic modeling, we examined the connection relationship between the word of interest and the word of interest. In addition, the influence of the word of interest in the network was measured using PageRank centrality. Through this analysis, it was found that there is a high interest in smart city-related construction, cities, and digital in both countries, and the difference in terms of interest between Korea and Vietnam was inferred. Finally, the limitations of this study and additional research directions to complement them are presented.

The search service, which is a core service of the portal site, presents search queries that are rapidly increasing among the inputted search queries based on the highest instantaneous search frequency, so it is difficult to immediately notify a search query having a high degree of interest for a certain period. Therefore, it is necessary to overcome the above problems and to provide more intelligent information retrieval service by bringing improved analysis results on the change of the search queries. In this paper, we present the criteria for measuring the interest, continuity, and attention of real-time search queries. In addition, according to the criteria, we measure and summarize changes in real-time search queries in hours, days, weeks, and months over a period of time to assess the issues that are of high interest, long-lasting issues of interest, and issues that need attention in the future.

Real-time search keywords are not only limited to search keywords that are rapidly increasing interest in real-time, but also have a limitation that they are difficult to determine the sustainability as there is a difference in ranking between portal sites. Estimating sustainability for real-time search keywords is significant in terms of overcoming these limitations and providing some predictability. In particular, long-term search keywords that last for more than a month are of high value as long-lasting social issues. Therefore, in this paper, we analyze the interest based on the ranking of the real-time search keywords and the duration based on sustained weeks, days and hours of real-time search keywords by each portal site and the integrated portal site, and then estimating sustainability based on high level of interest and duration, and present a method to derive real-time search issues with high long-term sustainability.

As the online media continues to evolve and the mobile computing environment has improved dramatically, the distribution of Internet information has rapidly changed from one-sided to consumer-oriented. Therefore, measuring the interest of Internet information has become an important issue for suppliers and consumers. In this paper, we analyze the Internet information interest by analyzing the duration of real - time query by collecting data for one month by implementing real - time search word provided by domestic Internet information provider.

인터넷 학술정보자원이 급증하고 있는 가운데 자동문헌분류에 대한 관심과 필요성도 늘어가고 있다. 자동문헌분류에 관한 실험은 전처리 단계인 대표색인어 추출과 추출된 대표색인어의 분류성능 평가 실험으로 구분 할 수 있는데, 본 연구에서는 우선 대표색인어 추출을 위해 다양한 대표색인어(자질) 추출 방법에 따른 색인어 성능평가 실험 및 최적의 대표색인어 개수 선정 실험을 수행하였다.

지표성은 두 가지 다른 철학적 관심에서 연구되어왔다. 하나는 지표어가 어떤 방식으로 그것이 지시하는 바를 지시하는가를 이해하는 의미론적 관심이고, 다른 하나는 지표어가 인식체계에서 담당하는 역할을 이해하는 행위 이론적 관심이다. 페리가 여러 문헌을 통해서 관심을 가져왔던 문제는 이 두 가지 철학적 관심을 모두 만족시키는 통일된 이론을 제시하는 것이었다고 생각된다. 그러나 이 두 관심사가 서로 구별된다는 점이 충분히 고려되지 않았으며, 왜 하나의 이론에서 함께 다루어져야 하는가에 대한 논변도 제시되지 않았다. 지표성 문제에 대한 페리의 해결책은 의미론적인 것이고 는 이를 통해 행위이론의 문제도 함께 해결된다고 주장한다. 그의 의미론적 해결책은 여러 가지로 변화되어 왔지만, 필자는 이 모두 만족스럽지 못하다는 것을 보이고자 한다. 페리의 이론이 가지고 있는 어려움의 근원은 필자가 '의미론적 토대주의'라고 부르는 입장을 페리가 고수하고 있기 때문이다. 지표성 문제에 대한 올바른 접근은 의미론적 토대주의를 처음부터 포기하는 것이라는 것이 필자의 제안이다.

Since realtime search words are centered on the fact that the search growth rate of an issue is rapidly increasing in a short period of time, it is not possible to express an issue that maintains interest for a certain period of time. In order to overcome these limitations, this paper evaluates the daily and hourly persistence of the realtime words that belong to the top 10 for a certain period of time and extracts the search word that are constantly interested. Then, we present the method of using the time series analysis and the neural network to know how the interest of the upper search word changes, and show the result of forecasting the near future change through the actual example derived through the method. It can be seen that forecasting through time series analysis by date and artificial neural networks learning by time shows good results.

본 연구에서는 인터넷 상의 많은 문서들 중에서 사용자에게 보다 적합한 문서를 제공하기 위해 퍼지 관계성을 이용하여 검색 결과 집합의 문서에서 추출한 키워드간의 유사클래스를 생성한다. 또한, 기존의 키워드 직접 매칭에 의한 검색 방법의 단점이라 할 수 있는 의미적 관계를 가지는 문서에 대한 검색 방법도 제안한다. 생성된 유사 클래스는 사용자의 질의를 확장하여 사용자의 관심도를 보다 많이 반영하게 되고, 그 질의어가 포함된 단어나 구의 발생 빈도수가 높은 문서에 대해 의미적으로 서로 연결시켜 분류한다. 본 연구에서 제안한 알고리즘에 의해 문서를 사용자 관심 정도로 분류, 카테고리를 생성하여 검색 효율을 증대시키고 사용자의 요구에 적합한 결과를 제공하고자 한다.

Realtime search words of typical portal sites appear every few seconds in descending order by search frequency in order to show issues increasing rapidly in interest. However, the characteristics of realtime search words reordering within too short a time cause problems that they go over the key issues of the day. This paper proposes a method for deriving a key issue through association analysis of realtime search words. The proposed method first makes scores of realtime search words depending on the ranking and the relative interest, and derives the top 10 search words through descriptive statistics for groups. Then, it extracts association rules depending on 'support' and 'confidence', and chooses the key issue based on the results as a graph visualizing them. The results of experiments show that the key issue through association rules is more meaningful than the first realtime search word.

Since the existing Web search engines don't sufficiently reflect user's search intent, it is very difficult to find out accurate information that users want to find. Therefore, a lot of researches, study for personalized search, to enhance satisfaction of Web search results by analyzing search pattern and applying it to search are in progress in these days. Web searchers can more efficiently find information and easily obtain appropriate information through the personalized search. In this paper, we propose the personalized search based on community through the analysis of web users' query patterns and interest. Consequently, when applying query frequency, interest and community to web search, we are able to the confirm that the search results which hit to the search intent of the individual are provided.
