Abstract

Describes the implementation and acceptance of an electronic syllabus on the WWW for teaching sociology. The greatest potential of a teaching home page on the Internet lies in a synergy effect of 3 domains: WWW pages serve as administrative tools, as powerful research instruments, and as a tool skill to prepare students for their careers in public or private institutions. Uses the empirical example of an electronic syllabus to illuminate potentials, problems and the acceptance of the Internet as an extended sociology classroom by students

Abstract

Many information professionals feel that the time is still far off when the WWW can offer the combined funtionality and content of traditional online and CD-ROM databases, but there have been a number of recent Web developments to reflect on. Describes the testing and launch by Ovid of its Java client which, in effect, allows access to its databases on the Web with full search functionality, and the initiative of Euromonitor in providing Web access to its whole collection of consumer research reports and its entire database of business sources. Also reviews the service of a newcomer to the information scene, Information Quest (IQ) founded by Dawson Holdings which has made an agreement with Infonautics to offer access to its Electric Library database thus adding over 1.000 reference, consumer and business publications to its Web based journal service

Abstract

Examines some of the advanced tools, techniques, methods and standards related to the Internet and WWW which consist of hybrids of documents and software, called 'document program hybrids'. Early Internet systems were based on having documents on one side and software on the other, neatly separated, apart from one another and without much interaction, so that the static document can also exist without computers and networks. Documentation program hybrids blur this classical distinction and all components are integrated, interwoven and exist in synergy with each other. Illustrates the techniques with particular reference to practical examples, including: dara collections and dedicated software; advanced HTML features on the WWW, multimedia viewer and plug in software for Internet and WWW browsers; VRML; interaction through a Web server with other servers and with instruments; adaptive hypertext provided by the server; 'webbots' or 'knowbots' or 'searchbots' or 'metasearch engines' or intelligent software agents; Sun's Java; Microsoft's ActiveX; program scripts for HTML and Web browsers; cookies; and Internet push technology with Webcasting channels

Abstract

A unique collection of historical material covering the lives and events of an English village between 1400 and 1750 has been made available via a WWW enabled information retrieval system. Since the expected readership of the documents ranges from school children to experienced researchers, providing this information in an easily accessible form has offered many challenges requiring tools to aid searching and browsing. The file structure of the document collection was replaced by an database, enabling query results to be presented on the fly. A Java interface displays each user's context in a form that allows for easy and intuitive relevance feedback

Abstract

Presents an approach that integrates searching and browsing in a manner that improves both paradigms. When browsing is the primary task, it enables semantic content-based tailoring of Web maps in both the generation as well as the visualization phases. When search is the primary task, it enables contextualization of the results by augmenting them with the documents' neighbourhoods. This approach is embodied in WebCutter, a client-server system fully integrated with Web software. WebCutter consists of a map generator running off a standard Web server and a map visualization client implemented as a Java applet runalble from any standard Web browser and requiring no installation or external plug-in application. WebCutter is in beta stage and is in the process of being integrated into the Lotus Domino application product line

Abstract

The KMODDL (kinematic models for design digital library) is a digital library based on a historical collection of kinematic models made of steel and bronze. The digital library contains four types of learning modules including textual materials, QuickTime virtual reality movies, Java simulations, and stereolithographic files of the physical models. The authors report an evaluation study on the uses of the KMODDL in two undergraduate classes. This research reveals that the users in different classes encountered different usability problems, and reported quantitatively different subjective experiences. Further, the results indicate that depending on the subject area, the two user groups preferred different types of learning modules, resulting in different uses of the available materials and different learning outcomes. These findings are discussed in terms of their implications for future digital library design.

Abstract

The Indiana University School of Library and Information Science opened a new research laboratory in January 2003; The Indiana University School of Library and Information Science Information Processing Laboratory [IU IP Lab]. The purpose of the new laboratory is to facilitate collaboration between scientists in the department in the areas of information retrieval (IR) and information visualization (IV) research. The lab has several areas of focus. These include grid and cluster computing, and a standard Java-based software platform to support plug and play research datasets, a selection of standard IR modules and standard IV algorithms. Future development includes software to enable researchers to contribute datasets, IR algorithms, and visualization algorithms into the standard environment. We decided early on to use OAI-PMH as a resource discovery tool because it is consistent with our mission.

Abstract

It is widely believed that many queries submitted to search engines are inherently ambiguous (e.g., java and apple). However, few studies have tried to classify queries based on ambiguity and to answer "what the proportion of ambiguous queries is". This paper deals with these issues. First, we clarify the definition of ambiguous queries by constructing the taxonomy of queries from being ambiguous to specific. Second, we ask human annotators to manually classify queries. From manually labeled results, we observe that query ambiguity is to some extent predictable. Third, we propose a supervised learning approach to automatically identify ambiguous queries. Experimental results show that we can correctly identify 87% of labeled queries with the approach. Finally, by using our approach, we estimate that about 16% of queries in a real search log are ambiguous.

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
