Abstract

Medical insurance fraud is common in many countries' medical insurance systems and represents a serious threat to the insurance funds and the benefits of patients. In this paper, we present an inference model of medical insurance fraud detection, based on a medical detection domain ontology that incorporates the knowledge base provided by the Medical Terminology, NKIMed, and Chinese Library Classification systems. Through analyzing the behaviors of irregular and fraudulent medical services, we defined the scope of the medical domain ontology relevant to the task and built the ontology about medical sciences and medical service behaviors. The ontology then utilizes Semantic Web Rule Language (SWRL) and Java Expert System Shell (JESS) to detect medical irregularities and mine implicit knowledge. The system can be used to improve the management of medical insurance risks.

Abstract

Reports results of a study to determine the presence of German libraries and companies on the WWW. The investigation included 60 German libraries (30 academic and 30 public libraries) and 50 German companies (30 publishers and 20 mail order firms). The aim was to evaluate the quality of their home pages in terms of information content, currency, graphics, clarity and service. The importance of a Web presence for libraries was found to be comparable to that for companies because of the common basis of production and delivery of output. A Web site is a means of speaking to a target group, transporting the corporate identity, and informing visitors to the site about current activities. It is important for marketing, by offering certain services such as electronic mail ordering via Internet and by presenting products in a new way on the Web. Results show that the currency of libraries' Web sites is far behind the ideal. Public libraries offer little service and rarely utilise the wide range of possibilities given by the WWW. Academic libraries have better service and strive to improve. Companies' home pages show better results than those of the libraries, most especially in the fields of design quality, clarity and coporate identity

Abstract

Describes the design and implementation of a system for computer generation of linked HTML documents to support information retrieval and hypertext applications on the WWW. The system does not require text query input, nor any client or host processing other than hypertext linkage. The goal is to construct a fully automatic system in which original text documents are read and processed by a computer program that generates HTML files, which can be used immediately by Web browsers to search and retrieve the original documents. A user with a large collection of information: for instance, newspaper articles; can feed these documents to this program and produce directly the necessary files to establish WWW home page and related pages, to support interactive retrieval and distribution of the original documents

Abstract

Michigan University owns one of the world's largest collection of ancient papyri and, in 1991, initiated a project to explore the use of image capture using electronic media scanners as a preservation and dissemination tool. The Michigan Papyri Digitization Project aimed to create a detailed online catalogue for researchers into the ancient Mediterranean world. The project team creted a WWW home page and made available sample images as a means of soliciting comments from experts in the field of papyrology. Notes the hardware and software selected for the task and sets out the steps taken to create the image database. Concludes with plans for the formation of an Advanced Papyrological Information System

Abstract

Reports from the Frakfurt Book Fair, 1996, considering the future of the CD-ROM market. The German home CD-ROM market is booming. 400 CD-ROM titles were published in 1994, 1.500 in 1995 and 2.000-2.500 are estimated for 1996. 720 million DM were earned from CD-ROMs in 1995. Future growth cannot be taken for granted. 3.000 to 5.000 copies must be sold to break even. Discusses the results of Andersen Consulting's survey of the German market; the best strategy for business and STM publishers; and how the EC fits into this scenario

Abstract

Highlights the important issues involved in the organization of non print materials, including arrangement by subject content and format. Highlights the advantages of conventional classification schemes such as LCC and DDC in arranging non print materials by subject content. They facilitate an integrated approach and are not difficult to understand where they are already in use. Close classification is preferred in order to derive the full benefits of conventional schemes. Home made schemes are confusing since they are completely new schemes or adulterations of existing ones. Compares and contrasts the practice in 2 university libraries in Nigeria

Abstract

There are numerous international and national programmes to encourage collaboration. However, little is known about the way in which collaboration changes the impact of a research publication. Explores hoe the impact (average citations per paper) varies with different types of collaboration. A calibrated bibliometric model is derived that demonstrates that collaborating with an author from the home institution or another domestic institution increases the average impact by about 0,75 citations while collaborating with an author from a foreign institution increases the impact by about 1.6 citations

Abstract

A major initiative at the Sandia National Laboratories Technical Library, New Mexico, is the provision of desktop access to information for Sandia researchers. During 1995, the library created a home page on the WWW with information on how to link to its client server based OPAC. Through multiple access points, researchers can search the catalogue from their desks and a new initiative is the provision of access to Sandia generated documents by converting them to electronic form, placing them on Sandia's 'internal Web' and linking them to the OPAC bibliographic record. Addresses the processes developed in the library and the procedures for cataloguing these electronic reports, including identification of the bibliographic information and MARC tags to be used

Abstract

Since Sep 1997 the catalogue of the French National Museum of Modern Art's documentation collection has been on the Internet. The original intention was to expand its function as a local collection management tool, and provide a worldwide reference source, using Z39.50. The process highlighted the catalogue's imperfection (local variations, exploded records). Future developments include an English version, refinement of the home pages and an updating programme. So far the impact is unclear, but this should eventually provide a basis for international cooperation

Abstract

Examines the growing and diverse full text CD-ROM marketplace. Attempts to discover the extent of fragmentation within this marketplace. Discusses the conflict between the design of such CD-ROMs for end user searching and the proliferation and diversification of retrieval software which bring into question the ease of use of CD-ROMs. identifies areas of expansion in this marketplace, including the home and schools' markets and specific subject areas, e.g. law, business and commerce and news information. Suggests that it will be interesting to see which search interface survive as the markets develops

Abstract

The Nordic SR-net project started in 1991, with the aim to develop communications between university library systems and union catalogues in all five Nordic countries, based on the ISO protocol Search and Retrieve. The plan was to develop totally integrated solutions, where the use interface of the remote systems would be hidden, and users can use their own interfaces from their own home systems

Abstract

The increasing expansion of the Internet has made resources available to users in sometimes unmanageable abundance. To help users manage this proliferation of information, librarians have begun to add URLs to their home pages. As well, specialized search engines are being used to retrieve information from selected sources in aneffort to return pertinent results. Describes the Harvest system which has been used to develop Index Antiquus, a specialized engine, for the classics and mediaeval studies. Presents a working example of how to search Index Antiquus

Abstract

Analyses the technical features of the 5 main search fields of the OPAC run by Bologna University's interlibrary centre (CIB), part of the National Library Service (SBN). The CIB links about 100 academic and civil library collections on the humanities, social sciences, and science subjects. With the aid of Home Page / Helpline displays, examines how OPAC search procedures are carried out by author, title, subject, ISBN, or single library. Also explains the data filtering methods used. The CIB will soon broaden its OPAC search strategies by adopting the Florence University library OPAC research structure

Abstract

The University of Regensburg Library was founded in 1964 as a collection of books on open access shelves. Therefore the Library established a new "home-made" classification scheme. Like LCC, a classmark consists in general of three principal elements: location number, classification number and author marks (formulated by Cutter and Sanborn). But unlike most academic libraries in Germany, Regensburg has developed its classification in line with the classification of a large group of German academic libraries. The 34 individual schedules are primarily kept up-to-date by: - Newsletter (semi-annual), published by the secretary at Regensburg - On-going contact between specialists and the secretary - New editions of the individual schedules appearing periodically Our plans in the field of classification include: - Updating according to developments in the sciences and humanities - Online classification
