기존의 문서 분석 시스템들은 형태소 분석기나 TF-IDF 기법을 통해 단어 위주의 분석을 진행하였다. 이러한 시스템들은 키워드들의 가중치를 계산하여 주요 키워드를 도출할 수 있는 장점이 있다. 이에 반해 문서의 내용을 분석하기에는 구조적인 한계로 인해 부적합한 실정이다. 이를 해결하기 위해 본 논문에서 제안하는 알고리즘은 문서 내에 있는 문단들의 가중치를 계산한 뒤 문단들을 영역별로 분할한다. 그리고 분할된 영역별로 중요도를 계산하여 해당 문서 내에 가장 중요한 문단들이 있는 영역을 사용자에게 알려준다. 이를 통해 사용자는 기존의 문서 분석 시스템들을 사용할 때보다 문서를 분석하기에 적합한 서비스를 제공받을 것으로 사료된다.

Despite limited success, today's information retrieval (IR) systems are not intelligent or reliable. IR systems return poor search results when users formulate their information needs into incomplete or ambiguous queries (i.e., weak queries). Therefore, one of the main challenges in modern IR research is to provide consistent results across all queries by improving the performance on weak queries. However, existing IR approaches such as query expansion are not overly effective because they make little effort to analyze and exploit the meanings of the queries. Furthermore, word sense disambiguation approaches, which rely on textual context, are ineffective against weak queries that are typically short. Motivated by the demand for a robust IR system that can consistently provide highly accurate results, the proposed study implemented a novel topic detection that leveraged both the language model and structural knowledge of Wikipedia and systematically evaluated the effect of query disambiguation and topic-based retrieval approaches on TREC collections. The results not only confirm the effectiveness of the proposed topic detection and topic-based retrieval approaches but also demonstrate that query disambiguation does not improve IR as expected.

This exploratory study investigated the software programs utilized by clinical dietitians and their perceptions on the use of information technology. The study focused on the use of specialized software for dietetics, general software for any office use and the Internet. A self-administered survey was used to collect data from clinical dietitians identified in the Kentucky Dietetic Association Directory 2003-2004. The survey was conducted in March through April, 2004. A total of 22 responses were collected, which yielded a response rate of $68\%$. Findings suggest that computer use has become a routine for optimal clinical practice ; major specialized software programs are used for nutrition assessment, nutrition analysis and menu development. Use of specialized software appears to be unassociated with dietitians' age and years of experience ; however, the associations are indicated between use of specialized software and education level as well as their specialty ; word processing and spreadsheet are the major general software used. Internet is used mainly for information search and communication. Respondents perceived that overall work efficiency and productivity significantly increased with computer use. The complexity of software is the major barrier encountered so training is the most needed support by the department. Strategic promotion on the use of specialized software should be targeted to the management team of the hospitals/facilities.

In the Russian 'spirituality' which played an important role in realization of 'abstraction' in modern arts, the three elements of Universalism - Oriental thoughts, Universal ideas, and Froebelian influence - can be found with no difficulty. More notable is the fact that, along with theosophy, the emergence of modern existential thoughts such as Bergson, Schopenhauer, Nietzsche is a new search and a new recognition of nature and human as views of panentheism and humanism, essentially of Humane and Divine. Therefore, it goes without saying that the thoughts constituting the Suprematism or Constructivism in Russia are, in a word, implicit in the existential humanistic ideas of Panpneumatism or Panentheism that is explained as the nature of Russian religious ideas. Furthermore, which is not only Suprematist's metaphysical principle but also the expression of universal thoughts; interestingly, which is closely akin to several Oriental mystic ideas including Taoist thoughts, as well as the contents of Universalism including mystic Christianity, by extension, which ideas and principles have a remarkable resemblance with thoughts and principles of Froebel.

In this paper, we propose a dynamic document classification method which breaks away from existing document classification method with artificial categorization rules focusing on suppliers and has changing categorization rules according to users' needs or social trends. The core of this dynamic document classification method lies in the fact that it creates classification criteria real-time by using topic modeling techniques without standardized category rules, which does not force users to use unnecessary frames. In addition, it can also search the details through the relevance analysis by calculating the relationship between the words that is difficult to grasp by word frequency alone. Rather than for logical and systematic documents, this method proposed can be used more effectively for situation analysis and retrieving information of unstructured data which do not fit the category of existing classification such as VOC (Voice Of Customer), SNS and customer reviews of Internet shopping malls and it can react to users' needs flexibly. In addition, it has no process of selecting the classification rules by the suppliers and in case there is a misclassification, it requires no manual work, which reduces unnecessary workload.

Most recent web search engines perform effective keyword-based multimedia contents retrieval by investigating keywords associated with multimedia contents on the Web and comparing them with query keywords. On the other hand, most music and compilation albums provide professional artwork as cover art that will be displayed when the music is played. If the cover art is not available, then the music player just displays some dummy or random images, but this has been a source of dissatisfaction. In this paper, in order to automatically create cover art that is matched with music contents, we propose a music album cover art creation scheme based on music contents analysis and result synthesis. We first (i) analyze music contents and their lyrics and extract representative keywords, (ii) expand the keywords using WordNet and generate various queries, (iii) retrieve related images from the Web using those queries, and finally (iv) synthesize them according to the user preference for album cover art. To show the effectiveness of our scheme, we developed a prototype system and reported some results.
