- Abstract
- Describes the first phase of an Internet training programme, presented to academic staff at Sydnay University, New South Wales, which included a brief introduction and comprehensive review of the Internet, using NCSA Mosaic and Netscape software as preseantation tools. The programme used locally produced Hypertext Markup Language (HTML) documents with live and 'canned' links to Internet tools and resources. Participants were presented with a 'things to see' home page on individual workstations and were free to explore areas of interest using this home page as a starting point. They were also provided with their own Mac and DOS discs as handouts with a World Wide Web (WWW) browser and local HTML documents, some of which contained links to Internet tools and resources. An evaluation of the programme indicated the success of the WWW browsers as an aid to Internet training

- Abstract
- Evaluates the performance of 8 major Internet search engines in answering 21 real reference questions and 5 made up subject questions. Reports on the retrieval and relevancy ranking abilities of the search engines. Concludes that the search engines did not produce good results for the reference questions unlike for the subject questions. The best engines are identified by type of questions, with Infoseek best for the subject questions, and OpenText best for refrence questions

- Abstract
- The growing number of networked information resources and services offers unprecedented opportunities for delivering high quality information to the computer desktop of a wide range of individuals. However, currently there is a reliance on a database retrieval model, in which endusers use keywords to search large collections of automatically indexed resources in order to find needed information. As an alternative to the database retrieval model, this paper outlines the classical digital library model, which is derived from traditional practices of library and information science professionals. These practices include the selection and organization of information resources for local populations of users and the integration of advanced information retrieval tools, such as databases and the Internet into these collections. To evaluate this model, library and information professionals and endusers involved with primary care medicine were asked to respond to a series of questions comparing their experiences with a digital library developed for the primary care population to their experiences with general Internet use. Preliminary results are reported

- Abstract
- Online discussion forums have become a popular medium for users to discuss with and seek information from other users having similar interests. A typical discussion thread consists of a sequence of posts posted by multiple users. Each post in a thread serves a different purpose providing different types of information and, thus, may not be equally useful for all applications. Identifying the purpose and nature of each post in a discussion thread is thus an interesting research problem as it can help in improving information extraction and intelligent assistance techniques. We study the problem of classifying a given post as per its purpose in the discussion thread and employ features based on the post's content, structure of the thread, behavior of the participating users, and sentiment analysis of the post's content. We evaluate our approach on two forum data sets belonging to different genres and achieve strong classification performance. We also analyze the relative importance of different features used for the post classification task. Next, as a use case, we describe how the post class information can help in thread retrieval by incorporating this information in a state-of-the-art thread retrieval model.

- Abstract
- The State Library of Iowa, USA, received a Higher Education Act title II grant from the US Dept. of Education in 1994 to create a demonstration project of new library information technologies. Describes 2 interlinked components of the project: Web-based union catalogue development and statewide deployment of the ANSI/NISO Z39.50 standard for database search and retrieval. Z39.50 was chosen because of its ability to searching multiple remote databases in a single session and its common interface across a variety of implementations. Use of a distributed Z39.50 search makes the need for maintaining large union catalogues unnecessary

- Abstract
- This paper describes the background underlying and the methods to be used in an investigation of use of the gopher protocol for browsing and searching for information via the Internet. Networked information resources are notoriously difficult to find; gopher is one attempt to facilitate the processes of organization and retrieval in that environment. Our project will design classification schemes based on traditional library models (i.e. Dewey and Library of Congress) and compare use of these to use of an existing gopher. We describe the project, the research questions, literature on related issues, the construction of the classification schemes, and the experimental methodology used

- Abstract
- In this research, we aim to identify factors that significantly affect the clickthrough of Web searchers. Our underlying goal is determine more efficient methods to optimize the clickthrough rate. We devise a clickthrough metric for measuring customer satisfaction of search engine results using the number of links visited, number of queries a user submits, and rank of clicked links. We use a neural network to detect the significant influence of searching characteristics on future user clickthrough. Our results show that high occurrences of query reformulation, lengthy searching duration, longer query length, and the higher ranking of prior clicked links correlate positively with future clickthrough. We provide recommendations for leveraging these findings for improving the performance of search engine retrieval and result ranking, along with implications for search engine marketing.

- Abstract
- Internet information retrieval is largely the preserve of search engines and the even more popular subject trees. Subject trees have adapted principles of conventional bibliographic classification for structuring hierarchic browsing interfaces, thus providing easily used pathways to their selected resources. This combination of browsing and selectivity is especially valuable to untrained users. For the forseeable future, it appears that subject trees will remain the Internet's only practicable use of classificatory methods for information retrieval

- Abstract
- Presents the findings of the South Ayrshire Libraries OPen Learning and the Internet project, Sep 1997 to Oct 1998. The objective was to demonstrate how open learning materials available on the Internet could be integrated with the provision of local open learning resources to provide an enhanced learning environment in public libraries. The main areas of concentration within the project were information skills support to public library users and the provision of WWW based independent materials to learners. The organisation and retrieval of Web based resources for local use was a major issue throughout the project. Recommends the adoption of Dublin Core metadata standards, the connection of databases of resources with searchable wen pages, and the development of thesauri of terms used to index the Web based resources locally. Sstaff training, and the new skills which will need to be developed, were identified as issues. Cost was also identified as a related issue, extending to issues such as access to open learning material and the Internet

- Abstract
- Technical information sources on the Internet are still relatively unstructured despite several attempts at indexing and despite the use of search mechanisms to bring such information sources together. Discusses, from the perspective of the concept of a clearinghouse, methods for the retrieval, concentration and structuring of technical information sources on the Internet for specific user groups. Cooperation between information institutions such as the German Research Society (DFG) special subject libraries and other similar special libraries can promote the establishment of value added services in the realm of information retrieval. Outlines the consequences of the increasing use of networked information sourvces on library work and on librarians' job profiles in general

- Abstract
- Lund University Library and the National Technological Library of Denmark carried out a 1 year NORDINFO-sponsored project from Summer 93. Part 1 was a demonstration of how an existing system, ALIS, can be integrated in the world of open client/server networking. A prototype is now in production at the Danish Library. Part 2 aimed at simplifying the use of WAIS database servers by establishing a WWW front-end service. In part 3 the use of WWW was simplified by supplementing the hypertext browsing with a search option based on a WAIS index of WWW resources. The heavy use of the pilot services demonstrates their need

- Abstract
- Cognitive science indicates that users of any system create internal representations ot it to enable them to structure knowledge. Conceptual models which include appropriate components, actions and interactions of a system provide students with a conceptual framework for accelerating learning. Describes a conceptual model of information retrieval within which is embedded a model of the Internet. Concludes that these models should help students from mature mental models so that they perceive information retrieval as a process and are able to make informed choices of when to use the Internet and to decide on suitable search strategies for different question types

- Abstract
- Finding information an the Web can be a much more complex search process than previously experienced an many pre-Web information retrieval systems given that finding content online does not have to happen via a search algorithm typed into a search field. Rather, the Web allows for a myriad of search strategies. Although there are numerous studies of Web search techniques, these studies often limit their focus to just one part of the search process and are not based an the behavior of the general user population, nor do they include information about the users. To remedy these shortcomings, this project looks at how peopie find information online in the context of their other media use, their general Internet use patterns, in addition to using information about their demographic background and social support networks. This article describes the methodology in detail, and suggests that a mix of survey instruments and in-person observations can yield the type of rich data set that is necessary to understand in depth the differences in people's information retrieval behavior online.

- Abstract
- Reports on experiences using WebSQL, a high level declarative query language for extracting information from the WWW. WebSQL takes advantage of multiplex index servers without requiring users to know about them, and integrates full-text with topology-based queries. Illustrates the use of WebSQL for application development by describing 2 applications: Web site maintenance and specialized index construction. Sketches several other possible applications. Using the library implements a client-server architecture that allows performance of interactive intelligent searches on the Web from an applet running on a browser
