Artificial Intelligence Lab, Department of MIS, University of Arizona / This article describes research in the application of a Kohonen Self-Organizing Map (SOM) to the problem of classification of electronic brainstorming output and an evaluation of the results. This research builds upon previous work in automating the meeting classification process using a Hopfield neural network. Evaluation of the Kohonen output comparing it with Hopfield and human expert output using the same set of data found that the Kohonen SOM performed as well as a human expert in representing term association in the meeting output and outperformed the Hopfield neural network algorithm. Recall of consensus meeting concepts and topics using the Kohonen algorithm was equivalent to that of the human expert.

Connections 2006 in Syracuse, NY, May 20-21 / This study analyses the tagging patterns exhibited by users of del.icio.us and citeulike. Frequency data, coword analysis and thesaural comparisons are used to examine tagging practices and determine where they are continuous or discontinuous with traditional classification and indexing. Results show many commonalities and some intriguing differences.

This is a scan of Putting Knowledge to Work: An American View of Ranganathan's Five Laws of Library Science by Pauline Atherton (aka Pauline A. Cochrane). This book includes publicly delivered essays and reflections on Ranganathan's five laws. It is the printed version of the first lecture of the Sixth Series of the Sarada Ranganathan Lectures in Library Science by Professor Pauline A. Atherton, Professor, School of Library Science, Syracuse University, New York, the Sarada Ranganathan Lecturer for 1970. Her speeches (Chapters D through K) form the main part of the book. Shri Guru Dutt, a distinguished citizen and a scholar in Bangalore, India inaugurated the evening and his inaugural speech is also included (Chapter C). In Chapter B, Professor Neelameghan delivers the Welcome Address and explains the objectives of the Sarada Ranganathan Endowment for Library Science (SRELS), which sponsors these lectures. Chapter A contains the preface to the series. SRELS was founded by Dr Ranganathan and his family, and incorporated with the Treasurer of Charitable Endowments for India in 1963. The objectives of SRELS are: 1. To further the cause of library science; 2. To organise periodically a course of lectures based on the latest ideas and research in library science and called the Sarada Ranganathan Lectures in Library Science; and 3. To assist in the publication of these lectures. This is a title in the dLIST Classics project. © Sarada Ranganathan Endowment for Library Science (SRELS).

Artificial Intelligence Lab, Department of MIS, University of Arizona / Law enforcement agencies across the United States have begun to focus on innovative knowledge management technologies to aid in the analysis of criminal information. The use of such technologies can serve as intelligence tools to combat criminal activity by aiding in case investigation or even by predicting criminal activity. Funded by the National Institute of Justice, the University of Arizonaâ s Artificial Intelligence Lab has teamed with the Tucson Police Department (TPD) to develop the Coplink Concept Space application, which serves to uncover relationships between different types of information currently existing in TPDâ s records management system. A small-scale field study involving real law enforcement personnel indicates that the use of Coplink Concept Space can reduce the time spent on the investigative task of linking criminal information as well as provide strong arguments for expanded development of similar knowledge management systems in support of law enforcement.

Artificial Intelligence Lab, Department of MIS, University of Arizona / Nanoscale science and engineering (NSE) and related areas have seen rapid growth in recent years. The speed and scope of development in the field have made it essential for researchers to be informed on the progress across different laboratories, companies, industries and countries. In this project, we experimented with several analysis and visualization techniques on NSE-related United States patent documents to support various knowledge tasks. This paper presents results on the basic analysis of nanotechnology patents between 1976 and 2002, content map analysis and citation network analysis. The data have been obtained on individual countries, institutions and technology fields. The top 10 countries with the largest number of nanotechnology patents are the United States, Japan, France, the United Kingdom, Taiwan, Korea, the Netherlands, Switzerland, Italy and Australia. The fastest growth in the last 5 years has been in chemical and pharmaceutical fields, followed by semiconductor devices. The results demonstrate potential of information-based discovery and visualization technologies to capture knowledge regarding nanotechnology performance, transfer of knowledge and trends of development through analyzing the patent documents.

This paper examines the tagging practices evident on CiteULike, a research oriented social bookmarking site for journal articles. Tagging practices were examined using standard informetric measures for analysis of bibliographic information and term use. Additionally, tags were compared to author keywords and descriptors assigned to the same article.

This is a preprint of the article published in Knowledge Organization 31 (3): 161-176. The work titled "Code for Classifiers" by William Stetson Merrill is examined. The development of Merrill's Code over a period of 27 years, 1912-1939 is traced by examining bibliographic, attribution, conceptual and contextual differences. The general principles advocated, the differences between variants, and three controversial features of the Code: 1) the distinction between classifying vs. classification, 2) borrowing of the bibliographic principle of authorial intention, and 3) use of Dewey Decimal class numbers for classified sequence of topics, are also discussed. The paper reveals the importance of the Code in its own time, the complexities of its presentation and assessment by its contemporaries, and itâ s status today.

Artificial Intelligence Lab, Department of MIS, University of Arizona / Presentation given by Hsinchun Chen at the NASA Meeting during PMSEP3 on the future of knowledge management. The presentation describes research performed by the Artificial Intelligence Lab at the University of Arizona to create a Perpetual Self-Organizing (PSO) approach to knowledge management funded by NSF, DARPA, NASA, NIJ, and NIH.

For well over a century, the catalog has served libraries and their users as a guide and index to publications collected by an institution. The attributes of the catalog that have made it a valuable resource are desirable traits in any information management tool.The Library catalog user has traditionally assumed that items listed in the catalog were carefully chosen to support an institutional mission and that they were available for her inspection. Internet portals, gateways to the Web, like the catalog, offer access to a wide range of resources, but differ from the catalog in a number of ways, perhaps most significantly in that they facilitate searching and retrieval from a vast, often uncoordinated array of sites, rather than the carefully delimited sphere of the library's collections. Web information has proven much more volatile, ephemeral, and heterogeneous. Can we re-interpret the catalog so that it can serve effectively as a portal to the Internet? Is the catalog the appropriate model for discovery and retrieval of highly dynamic, rapidly multiplying, networked documents? Until relatively recently, the catalog has been the dominant index to published literature for library users. Web portals are rapidly usurping this primacy. Libraries today are struggling as they strain to incorporate a variety of resources in diverse formats in their catalogs and to maintain centrality and relevancy in the digital world. This paper will examine the features of the catalog and their portability to the Web, and will make recommendations about the Library catalog's role in providing access to Internet resources.
