Abstract

Reports results of a questionnaire survey of cataloguers in academic libraries, belonging to the ALA, Technical Services division, to determine how their job functions have changed over the previous 10 years. The 271 respondents compiled a questionnaire listing 67 traditional and emerging activities in which academic library cataloguers are involved, including: the change from print to electronic formats; involvement of non professional library staff in higher levels of cataloguing; the trend towards outsourcing (contracting out), particularly copy cataloguing and foreign language materials; and increasing involvement with specialized items, audiovisual materials and digital materials. Professional librarians now use their expertise to edit problematic records, engage in managerial tasks, catalogue and provide authority control of Internet resources, do Internet training or Web site design and use HTML. Cataloguers are increasingly involved in the former domain of systems librarians

Abstract

Reports results of a study of 4 WWW search engines: AltaVista; Lycos; Excite and WebCrawler to collect data on Web objects on polymer chemistry. 1.037 Web objects were examined for data in 4 categories: document information; use of meta fields; use of images and use of chemical names. Issues raised included: whether to provide metadata elements for parts of entities or whole entities only, the use of metasyntax, problems in representation of special types of objects, and whether links should be considered when encoding metadata. Use of metafields was not widespread in the sample and knowledge of metafields in HTML varied greatly among Web object creators. The study formed part of a metadata project funded by the OCLC Library and Information Science Research Grant Program

Abstract

Within a digital library, collections may range from an ad hoc set of objects that serve a temporary purpose to established library collections intended to persist through time. The objects in these collections vary widely, from library and data center holdings to pointers to real-world objects, such as geographic places, and the various metadata schemes that describe them. The key to integrated use of such a variety of collections in a digital library is collection metadata that represents the inherent and contextual characteristics of a collection. The Alexandria Digital Library (ADL) Project has designed and implemented collection metadata for several purposes: in XML form, the collection metadatada 'registers' the collection with the user interface client; in HTML form, it is used for user documentation; eventually, it will be used to describe the collection to network search agents; and it is used for internal collection management, including mapping the object metadata attributes to the common search parameters of the system

Abstract

Language barrier is the major problem that people face in searching for, retrieving, and understanding multilingual collections on the Internet. This paper deals with query translation and document translation in a Chinese-English information retrieval system called MTIR. Bilingual dictionary and monolingual corpus-based approaches are adopted to select suitable tranlated query terms. A machine transliteration algorithm is introduced to resolve proper name searching. We consider several design issues for document translation, including which material is translated, what roles the HTML tags play in translation, what the tradeoff is between the speed performance and the translation performance, and what from the translated result is presented in. About 100.000 Web pages translated in the last 4 months of 1997 are used for quantitative study of online and real-time Web page translation

Abstract

A detailed description of how to use Java applets and Common Gateway Interface (CGI)/Dynamic Link Library (DLL) programs for Web publication of textual databases. The advantages of Java applets include low cost, flexible and visually appealing search interfaces, and the ability to be embedded in HTML pages, eliminating the need for Internet service provider permissions for their use. Highlights the FindIt family of Java applets from DoubleOLogic as one of the best product lines in the category. CGI programs may be written in Perl, Java, or some other language, and like DLL programs, must be installed on the server side. Notes that small-scale CGI and DLL applications cost from $150 to $8,000. Highlights Insight from Enigma Inc. as an excellent program at the high end of the cost range

Abstract

My goal in this short article is to bring you up to speed on Web indexing. I assume you are a person with good word skills and an inquisitive mind. Also, I assume you have good keyboard skills, access to the Internet, and have already created some HTML pages using, say, Netscape Composer. You may need help from your Internet Service Provider (ISP) to upload pages onto your Web site. This article is based on my experience teaching an online interactive course in Web indexing for my company, WWWalker Web Development, in 1998. We develop Web sites, support Linux and Windows NT, write technical articles, and specialize in Web indexing.

Abstract

This study reports an analysis of American Chemical Society electronic journal downloads at Cornell University by individual IP addresses. While the majority of users (IPs) limited themselves to a small number of both journals and article downloads, a small minority of heavy users had a large effect an total journal downloads. There was a very strong relationship between the number of article downloads and the number of users, implying that a user-population can be estimated by just knowing the total use of a journal. Aggregate users (i.e. Library Proxy Server and public library computers) can be regarded as a sample of the entire user population. Analysis of article downloads by format (PDF versus HTML) suggests that individuals are using the system like a networked photocopier, for the purposes of creating print-on-demand copies of articles.

Abstract

We consider the problem of storing and accessing documents (SGML and HTML, in particular) using database technology. To specify the database image of documents, we use structuring schemas that consist in grammars annotated with database programs. To query documents, we introduce an extension of OQL, the ODMG standard query language for object databases. Our extension (named OQL-doc) allows us to query documents without a precise knowledge of their structure using in particular generalzed path expressions and pattern matching. This allows us to introduce in a declarative langugae (in the style of SQL or OQL), navigational and information retrieval styles of accessing data. We also consider the interaction of full-text indexes (e.g. inverted files) with standard database collection indexes (e.g, B-trees) that provide important speed-up

Abstract

Describes an approach to the processing and presentation of online full-text journals that utilizes several evolving information technologies, including extensible markup language (XML) and extensible stylesheet language transformations (XSLT). Discusses major issues and trade-offs associated with these technologies, and also specific lessons learned from our use of these technologies in the Illinois Testbed of full-text journal articles. Focuses especially on issues associated with the representation of documents in XML, techniques to create and normalize metadata describing XML document instances, XSLT features employed in the Illinois Testbed, and trade-offs of different XSLT implementation options. Pays special attention to techniques for transforming between XML and HTML formats for rendering in today's commercial Web browsers.

Abstract

Library users expect to find an increasing array of information resources on the Web, and libraries have been using that medium. However, much of what they supply on the Web is static data such as bibliographies, pathfinders, instructions, and schedules. Providing dynamic data on the Web, especially from a relational database, can be a daunting task because HTML is a markup language that has little processing power. This paper will discuss the steps necessary to provide dynamic Web access to local databases using active server pages (ASP) technology. ASP is easier to use than other methods because it imbeds scripting statements directly into the Web page, rather than relying on separate, complicated programs. Software necessary to make it work resides on the server, and the end-user does not have to worry about it. Several working examples will illustrate techniques for searching and displaying data from a Microsoft Access database using ASP.

Abstract

Thelwall and Wilkinson use crawls of university web sites in the UK, Australia, and New Zealand to generate all links targeted at same country university web sites which they then use to create a graph structure for study. Using Broder's study as a model they identify a strongly connected component, SCC, where one could start anywhere in the set and reach every other page, and an Out component whose pages can be reached from all strongly connected pages but provide no link back to that set. The other components in the Broder model are not accessible except with access to a major search engine database. In link and out link counts for all three university systems in both the Out and SCC components when graphed logarithmically display the linear nature which would indicate that power laws, and a success breeds success phenomena, are generally in effect. However, automatically generated pages, non-HTML web pages, and large resource-driven sites all were associated with anomalies in this observation.

Abstract

In this article Web issue analysis is introduced as a new technique to investigate an issue as reflected on the Web. The issue chosen, integrated water resource management (IWRM), is a United Nations-initiated paradigm for managing water resources in an international context, particularly in developing nations. As with many international governmental initiatives, there is a considerable body of online information about it: 41.381 hypertext markup language (HTML) pages and 28.735 PDF documents mentioning the issue were downloaded. A page uniform resource locator (URL) and link analysis revealed the international and sectoral spread of IWRM. A noun and noun phrase occurrence analysis was used to identify the issues most commonly discussed, revealing some unexpected topics such as private sector and economic growth. Although the complexity of the methods required to produce meaningful statistics from the data is disadvantageous to easy interpretation, it was still possible to produce data that could be subject to a reasonably intuitive interpretation. Hence Web issue analysis is claimed to be a useful new technique for information science.
