A Study on the Structures and Characteristics of National Policy Knowledge
Lee, Ji-Sue ; Chung, Young-Mee ;
Journal of Information Management, volume 41, issue 2, 2010, Pages 1~30
DOI : 10.1633/JIM.2010.41.2.001
This study analyzed research output in dominant research areas of 19 national research institutions. Policy knowledge produced by the institutions during the past 5 years mainly concerned 10 policies dealing with economy and society issues. Similarities between the research subjects of the institutions were displayed by MDS mapping. The study also identified issue attention cycles of the 5 chosen policies and examined the correlation between the issue attention cycles and the yields of policy knowledge. The knowledge structure of each policy was mapped using co-word analysis and Ward's clustering. It was also found that the institutions performing research on similar subjects demonstrated citation preferences for each other.

Now named-entity recognition(NER) as a part of information extraction has been used in the fields of information retrieval as well as question-answering systems. Unlike words, named-entities(NEs) are generated and changed steadily in documents on the Web, newspapers, and so on. The NE generation causes an unknown word problem and makes many application systems with NER difficult. In order to alleviate this problem, this paper proposes a new feature generation method for machine learning-based NER. In general features in machine learning-based NER are related with words, but entities in named-entity dictionaries are related to phrases. So the entities are not able to be directly used as features of the NER systems. This paper proposes an encoding scheme as a feature generation method which converts phrase entities into features of word units. Futhermore, due to this scheme, entities with semantic information in WordNet can be converted into features of the NER systems. Through our experiments we have shown that the performance is increased by about 6% of F1 score and the errors is reduced by about 38%.

Open innovation is a phenomenon that has been widely accepted by both practice and theory over the last few years. On the contrary, partner relationships have attracted little attention while the open innovation could not be emerged without the link to partners. This paper identifies and evaluates a framework for the partner relationships and open innovation processes. Based on the literatures regarding open innovation and partner relationships, we propose the framework of matrix type. We present results based on 352 open innovation cases reported during 2002-2009, and each case is classified into 5 different categories of the framework. JV-C(Joint Venture relationship & Coupled process) archetype has dominated the cases with 178 cases(50.6%) where JV-O(Joint Venture relationship & Outside-In process) follows JV-C with 124 cases(35.2%). No significant change has been found in the number of cases after 2003 when open innovation firstly suggested. However, the number sharply increases in 2009 by boom in JV-C and JV-O. These results show the importance of partner relationships and preference toward Joint Venture relationship in open innovation, while the conventional approaches has just focused on value-chain partnership. We find remarkable collaboration cases contributed by universities and government invested research centers, so the role of non-profit R&D organizations has also been discussed.
A Study on Building Cooperation Model for the Public Availability of Materials and Information on North Korea
Song, Sung-Seob ;
Journal of Information Management, volume 41, issue 2, 2010, Pages 71~93
DOI : 10.1633/JIM.2010.41.2.071
This study firstly considered the changing processes of the 'guideline on dealing with restricted materials and information' which had been theoretical background for understanding the dealing situations of materials and information on North Korea. Additionally, this study investigated material possessions which were located in restricted-materials-dealing institutions affiliated with Ministry of Unification and Ministry of Education, Science and Technology, and also researched using results of the materials. Through the investigation analysis and precedent studies, problems caused by poor material using conditions were found and institutional developing plans were sought. In particular, this study suggested that 'the Interchange Council for North Korean Information and Materials' be constructed as a general management organization which controls many problems caused by using and treating materials and information on North Korea and cooperative models that can lead organic connection among all institutions for dealing with restricted materials and information.
Study on the Building up the Laboratory Database: Case Study from the KOSEN OpenLab Service
Yoon, Jung-Sun ; Jung, Hye-Ju ; Hahn, Sun-Hwa ;
Journal of Information Management, volume 41, issue 2, 2010, Pages 95~110
DOI : 10.1633/JIM.2010.41.2.095
We studied the methods for boosting a user participating service using KOSEN(The Global Network or Korean Scientists and Engineers) OpenLab service. OpenLab is a laboratory database of all the fields of science and technology, and it is different from other services in that basically it makes users register their information volunteerly. User participation service is not easy, so we made several strategies like promotion, event, and connection to other services. In result, we could collect about 4,300 laboratory database. Because user participation is a key concept for the Web 2.0, this study would contribute to the operation of the related services, especially to the services for scientists and engineers.
Analyzing the Influence Factors on Efficiency of Public Libraries in Metropolitan Cities by DEA and Tobit Model
Lee, Sang-Su ; Han, Ha-Neul ;
Journal of Information Management, volume 41, issue 2, 2010, Pages 111~131
DOI : 10.1633/JIM.2010.41.2.111
This paper examines the levels and influence factors on efficiency of public libraries in metropolitan cities. For this purpose, In the first stage, the efficiency score analysis of 129 sample public libraries has been undertaken. In the second stage, the efficiency scores obtained from the first stage are regressed on environmental factors. The result of this study shows that : (1) main source of technical inefficiency is pure technical inefficiency rather than scale inefficiency; (2) it is positive effect environmental factors on the efficiency that the population, the dummy variable of capital area.
Some Legal Arguments on the Google Book Search and Library Information Digitization

Books in libraries can be highly refined information. Google invests digitization of books in libraries. But the digitization of books that has a variety of interests, coupled with several problems, including class action, in addition the many critical discussions are underway. Korea pushed the national digitization projects, what are libraries' digitizing their collection of many books. Of course, in publishing and digitization of the target is limited to books published ahead of Google. However, the Library Act was amended for the reposition of online materials, but only in the ways that Google's case is different. Library Act permits collection of online resources through the library to allow, the legislation can be considered as leading act. However, online data is publicly not available through the Internet, so this service hae limited means and range unlike Google. This paper, the digitization of books in the library due to copyright, examines the legal issues looking for the desirable solution. Physical library's main role had been kept the book, but we use the book in terms of policies needed to consider. To overcome these limitations of Copyright Act, this paper researches the relation of Google Book Search in our Copyright Act, and considers introduction as the fair use doctrine and the digital repository system.

DOI : 10.1633/JIM.2010.41.2.161
The purpose of this study is to investigate citation behavior in internet news to research papers of 10 domestic economic institutes and to suggest institutes' impact quantitatively with h-index and various modified indices. Content analysis of 878 news articles that collected from NAVER news site was performed. First, as citing behavior, cited numbers of research papers, preferred news media, speed, source entry accuracy, centrality, subject section, and length by the institutes were examined. Next, impact indices for institutes were calculated by cited numbers using h-index, g-index,
-index, and the ranking of 10 research institutes were determined by each impact indices. As a result, institutes belonged to upper ranks showed little variation among the different indices. On the other hand, institutes belonged to middle and lower ranks showed variations in impact indices and experts' survey.
