  Park, H. ; You, S. ; Wolfram, D.: Informal data citation for data sharing and reuse is more common than formal data citation in biomedical fields.
  In: Journal of the Association for Information Science and Technology. 69(2018) no.11, S.1346-1354.
  
  Abstract: Data citation, where products of research such as data sets, software, and tissue cultures are shared and acknowledged, is becoming more common in the era of Open Science. Currently, the practice of formal data citation-where data references are included alongside bibliographic references in the reference section of a publication-is uncommon. We examine the prevalence of data citation, documenting data sharing and reuse, in a sample of full text articles from the biological/biomedical sciences, the fields with the most public data sets available documented by the Data Citation Index (DCI). We develop a method that combines automated text extraction with human assessment for revealing candidate occurrences of data sharing and reuse by using terms that are most likely to indicate their occurrence. The analysis reveals that informal data citation in the main text of articles is far more common than formal data citations in the references of articles. As a result, data sharers do not receive documented credit for their data contributions in a similar way as authors do for their research articles because informal data citations are not recorded in sources such as the DCI. Ongoing challenges for the study of data citation are also outlined.

  Choi, S. ; Yang, J.S.W. ; Park, H.W.: ¬The triple helix and international collaboration in science.
  In: Journal of the Association for Information Science and Technology. 66(2015) no.1, S.201-212.
  
  Abstract: Previous studies of international scientific collaboration have rarely gone beyond revealing the structural relationships between countries. Considering how scientific collaboration is actually initiated, this study focuses on the organization and sector levels of international coauthorship networks, going beyond a country-level description. Based on a network analysis of coauthorship networks between members of the Organisation for Economic Cooperation and Development (OECD), this study attempts to gain a better understanding of international scientific collaboration by exploring the structure of the coauthorship network in terms of university-industry-government (UIG) relationships, the mode of knowledge production, and the underlying dynamic of collaboration in terms of geographic, linguistic, and economic factors. The results suggest that the United States showed overwhelming dominance in all bilateral UIG combinations with the exception of the government-government (GG) network. Scientific collaboration within the industry sector was concentrated in a few players, whereas that between the university and industry sectors was relatively less concentrated. Despite the growing participation from other sectors, universities were still the main locus of knowledge production, with the exception of 5 countries. The university sector in English-speaking wealthy countries and the government sector of non-English-speaking, less-wealthy countries played a key role in international collaborations between OECD countries. The findings did not provide evidence supporting the institutional proximity argument.

  Leydesdorff, L. ; Park, H.W. ; Wagner, C.: International coauthorship relations in the Social Sciences Citation Index : is internationalization leading the Network?.
  In: Journal of the Association for Information Science and Technology. 65(2014) no.10, S.2111-2126.
  
  Abstract: International coauthorship relations have increasingly shaped another dynamic in the natural and life sciences during recent decades. However, much less is known about such internationalization in the social sciences. In this study, we analyze international and domestic coauthorship relations of all citable items in the DVD version of the Social Sciences Citation Index 2011 (SSCI). Network statistics indicate 4 groups of nations: (a) an Asian-Pacific one to which all Anglo-Saxon nations (including the United Kingdom and Ireland) are attributed, (b) a continental European one including also the Latin-American countries, (c) the Scandinavian nations, and (d) a community of African nations. Within the EU-28, 11 of the EU-15 states have dominant positions. In many respects, the network parameters are not so different from the Science Citation Index. In addition to these descriptive statistics, we address the question of the relative weights of the international versus domestic networks. An information-theoretical test is proposed at the level of organizational addresses within each nation; the results are mixed, but the international dimension is more important than the national one in the aggregated sets (as in the Science Citation Index). In some countries (e.g., France), however, the national distribution is leading more than the international one. Decomposition of the United States in terms of states shows a similarly mixed result; more U.S. states are domestically oriented in the SSCI and more internationally in the SCI. The international networks have grown during the last decades in addition to the national ones but not by replacing them.

  Park, H. ; Smiraglia, R.P.: Enhancing data curation of cultural heritage for information sharing : a case study using open Government data.
  In: Metadata and semantics research: 8th Research Conference, MTSR 2014, Karlsruhe, Germany, November 27-29, 2014, Proceedings. Eds.: S. Closs et al. Cham : Springer, 2014. S.95-106.

  Abstract: The purpose of this paper is to enhance cultural heritage data curation. A core research question of this study is how to share cultural heritage data by using ontologies. A case study was conducted using open government data mapped with the CIDOC-CRM (Conceptual Reference Model). Twelve library-related files in unstructured data format were collected from an open government website, Seoul Metropolitan Government of Korea (http://data.seoul.go.kr). By using the ontologies of the CIDOC CRM 5.1.2, we conducted a mapping process as a way of enhancing cultural heritage information to share information as a data component. We graphed each file then mapped each file in tables. Implications of this study are both the enhanced discoverability of unstructured data and the reusability of mapped information. Issues emerging from this study involve verification of detail for complete compatibility without further input from domain experts.

  Park, H.: ¬A conceptual framework to study folksonomic interaction.
  In: Knowledge organization. 38(2011) no.6, S.515-529.
  
  Abstract: This paper proposes a conceptual framework to recast a folksonomy as a Web classification and to use this to explore the ways in which people work with it in assessing, sharing, and navigating Web resources. The author uses information scent and foraging theory as a context to discuss how folksonomy is constructed through interactions among users, a folksonomic system, and a given domain that consists of a group of users who share the same interest or goals. The discussion centers on two dimensions of folksonomies: (1) folksonomy as a Web classification which puts like information together in a Web context; and (2) folksonomy as information scent which helps users to find related resources and users, and obtain desired information. This paper aims to integrate these two dimensions with a conceptual framework that addresses the structure of a folksonomy shaped by users' interactions. A proposed framework consists of three components of users' interactions with a folksonomy: (a) tagging - cognitive categorization of Web accessible resources by an individual user; (b) navigation - exploration and discovery of Web accessible resources in the folksonomic system; and (c) knowledge sharing - representation and communication of knowledge within a domain. This understanding will help us motivate possible future directions of research in folksonomy. This initial framework will frame a number of research questions and help lay the groundwork for future empirical research which focuses on qualitative analysis of a folksonomy and users' tagging behaviors.

  Khan, G.F. ; Park, H.W.: Measuring the triple helix on the web : longitudinal trends in the university-industry-government relationship in Korea.
  In: Journal of the American Society for Information Science and Technology. 62(2011) no.12, S.2443-2455.
  
  Abstract: This study examines longitudinal trends in the university-industry-government (UIG) relationship on the web in the Korean context by using triple helix (TH) indicators. The study considers various Internet resources, including websites/documents, blogs, online cafes, Knowledge-In (comparable to Yahoo! Answers), and online news sites, by employing webometric and co-word analysis techniques to ascertain longitudinal trends in the UIG relationship, which have received considerable attention in the last decade. The results indicate that the UIG relationship varied according to the government's policies and that there was some tension in the longitudinal UIG relationship. Further, websites/documents and blogs were the most reliable sources for examining the strength of and variations in the bilateral and trilateral UIG relationships on the web. In addition, web-based T(uig) values showed a stronger trilateral relationship and larger variations in the UIG relationship than Science Citation Index-based T(uig) values. The results suggest that various Internet resources (e.g., advanced search engines, websites/documents, blogs, and online cafes), together with TH indicators, can be used to explore the UIG relationship on the web.

  Kim, J.H. ; Barnett, G.A. ; Park, H.W.: ¬A hyperlink and issue network analysis of the United States Senate : a rediscovery of the Web as a relational and topical medium.
  In: Journal of the American Society for Information Science and Technology. 61(2010) no.8, S.1598-1611.
  
  Abstract: Politicians' Web sites have been considered a medium for organizing, mobilizing, and agenda-setting, but extant literature lacks a systematic approach to interpret the Web sites of senators - a new medium for political communication. This study classifies the role of political Web sites into relational (hyperlinking) and topical (shared-issues) aspects. The two aspects may be viewed from a social embeddedness perspective and three facets, as K. Foot and S. Schneider ([2002]) suggested. This study employed network analysis, a set of research procedures for identifying structures in social systems, as the basis of the relations among the system's components rather than the attributes of individuals. Hyperlink and issue data were gathered from the United States Senate Web site and Yahoo. Major findings include: (a) The hyperlinks are more targeted at Democratic senators than at Republicans and are a means of communication for senators and users; (b) the issue network found from the Web is used for discussing public agendas and is more highly utilized by Republican senators; (c) the hyperlink and issue networks are correlated; and (d) social relationships and issue ecologies can be effectively detected by these two networks. The need for further research is addressed.

  Park, H.W. ; Barnett, G.A. ; Nam, I.-Y.: Hyperlink - affiliation network structure of top Web sites : examining affiliates with hyperlink in Korea.
  In: Journal of the American Society for Information Science and technology. 53(2002) no.7, S.592-601.
  
  Abstract: This article argues that individual Web sites form hyperlink-affiliations with others for the purpose of strengthening their individual trust, expertness, and safety. It describes the hyperlink-affiliation network structure of Korea's top 152 Web sites. The data were obtained from their Web sites for October 2000. The results indicate that financial Web sites, such as credit card and stock Web sites, occupy the most central position in the network. A cluster analysis reveals that the structure of the hyperlink-affiliation network is influenced by the financial Web sites with which others are affiliated. These findings are discussed from the perspective of Web site credibility.

  Park, H.: Relevance of science information : origins and dimensions of relevance and their implications to information retrieval.
  In: Information processing and management. 33(1997) no.3, S.339-352.
  
  Abstract: 24 graduate students' relevance judgements were observed to find dimensions and characteristics of relevance. Findings were: that relevance is multidimensional; that there are 2 types of relevance dimensions, primary and secondary; that relevance dimensions show 3 orientations, problem, use, and value; and that the problem orientation is primary to the other orientations. The implications of these findings are that: 4 characteristics of important relevance dimensions were found; the important dimensions need to be applied to the system's measurement of relevance; relationships between thesaurus terms need to be set following the important dimensions; the important dimensions are useful for the effective evaluation of information retrieval; and that these and the orientations of relevance are useful to observe users' relevance judgements of the study of variables affecting relevance judgements

  Park, H.: Inferential representation of science documents.
  In: Information processing and management. 32(1996) no.4, S.419-429.
  
  Abstract: The inferential communication model, which implies that the meaning of a document is inferred in the context of the user's situation to result in different meanings for users in different situations, is used to study an inferential science document representation method. Several topical components and non topical components of the science document were found as the inferred meanings of the document. These show the science document aspects which are used for relevance judgements. Science documents need to be represented in terms of these aspects for effective system's, intermediary's, and user's judgements of the meaning and the relevance of the document
