- Abstract
- The availability of powerful indexing and database products with easy Web connections means that libraries able to gather and edit their own data are emancipated from the large vendors. The Oregon State Library staff used the Data Magician translation utility as part of a complex, but speedy, database converison project. The Oregon Index database of approximately 300.000 records was converted from a BRS database host over to the Inmagic WebPublisher system. Describes the planning and action stepts used in producing the Web accessible index database of considerable size. Participants have high ratings to effectiveness of both the translation utility and the database engine

- Abstract
- Reports on the Southern California Online Users Group annual workshop, which broke all previous attendance records. The topic was 'Radical redesign of reference and research', and common threads among speakers included the need for a new reference/research model that will scale with future needs, and the now common standard of round the clock service availability. Print could become a secondary medium to digital data, primarily delivered over the Internet, and that information vendors be forced to change pricing structures. Librarians from public, corporate, and academic sectors have begun building Web sites around links to their own data and to other quality sites as a means of providing 24 hour services. Vendors might consider creating new price comparison services, or offering proce guarantees, to compete with this new phenomenon

- Abstract
- This paper argues that the Semantic Web needs to incorporate both formal and associative structures (and possibly a multitude of other structures and strategies) to be successful. The arguments for this claim are based on an observation of successes and failures in the areas of artificial intelligence (AI) and natural language processing (NLP). 1. Introduction The WWW provides numerous challenges for information and knowledge processing activities. Information may be available but not accessible or retrievable because of language barriers or insufficient search strategies. Data mining techniques may discover implicit information in explicit data but these techniques do not necessarily guarantee that the discovered information is relevant, significant and trustworthy. During the last several decades hundreds or thousands of computer and information scientists have developed probably thousands of natural language processing and artificial intelligence techniques that were aimed at solving problems related to intelligent information processing only to encounter more and more new obstacles along the way. The latest solution, the Semantic Web, appears as an open declaration of defeat: since natural language processing and AI techniques did not provide sufficient results, it is now proposed to put the burden an the shoulder of the authors of webpages who are expected to populate their pages with metadata and additional markup. Metadata is essentially a new form of controlled vocabulary; markup - at least in the form of XML, XSL, etc - is essentially a programming language. Existing studies of the use of controlled vocabularies and indexing practices in information science and studies of teaching programming languages to "everybody" (Python, 2002) have shown that both are difficult and full of unsolved problems. This can further dampen the expectations of the success of the Semantic Web. In contrast to machines and despite numerous inter-cultural conflicts around the world, humans do communicate surprisingly successfully even across national, linguistic and cultural boundaries. The question then arises: why are humans successful at information processing tasks such as information integration, translation and communication, which computers find so difficult? One obvious answer is that human cognition is embodied and grounded in our shared experiences of living in the same world. AI researchers have theoretically explored the idea of symbol grounding in the early 1990's but so far, connectionist artificial agents with perceptual interfaces have not been integrated with a large-scale capability of symbolic representations.

- Abstract
- State of the art review of the Net (the global telecommunications network as a whole) and the Internet with particular reference to the development of a coherent policy for those uisng these telecommunications facilities. Policy issues discussed include: standards, intellectual property; encryption, rules for transborder data flow; and data privacy. Considers their implications for individuals as well as government and commercial institutions. The review is limited to English language publications and explores specific issues that affect the structure of government, the economy and society, as well as those involved in the design of the net and looks at comparative and international issues. Concludes that the development of policies for the net is made difficult by the many different bodies of law that apply, by the fact that the relevant technologies are new and changing because that technologies are new and rapidly changing and because the net is global. Specific characteristics of the net require new thinking on a constitutional level, since information creation, processing, flows and use are constitutive forces in society

- Abstract
- Indexing remains one of the most popular tools provided by digital libraries to help users identify and understand the characteristics of the information they need. Despite extensive studies of the problem of automatic index construction for text-based digital libraries, the construction of multimedia digital libraries continues to represent a challenge, because multimedia objects usually lack sufficient text information to ensure reliable index learning. This research attempts to tackle the problem of automatic index construction for multimedia objects by employing Web usage logs and limited keywords pertaining to multimedia objects. The tests of two proposed algorithms use two different data sets with different amounts of textual information. Web usage logs offer precious information for building indexes of multimedia digital libraries with limited textual information. The proposed methods generally yield better indexes, especially for the artwork data set.

- Abstract
- Previous studies of academic web interlinking have tended to hypothesise that the relationship between the research of a university and links to or from its web site should follow a linear trend, yet the typical distribution of web data, in general, seems to be a non-linear power law. This paper assesses whether a linear trend or a power law is the most appropriate method with which to model the relationship between research and web site size or outlinks. Following linear regression, analysis of the confidence intervals for the logarithmic graphs, and analysis of the outliers, the results suggest that a linear trend is more appropriate than a non-linear power law.

- Abstract
- Information extraction systems discover structured information in natural language text. Having information in structured form enables much richer querying and data mining than possible over the natural language text. However, information extraction is a computationally expensive task, and hence improving the efficiency of the extraction process over large text collections is of critical interest. In this paper, we focus on an especially valuable family of text collections, namely, the so-called deep-web text collections, whose contents are not crawlable and are only available via querying. Important steps for efficient information extraction over deep-web text collections (e.g., selecting the collections on which to focus the extraction effort, based on their contents; or learning which documents within these collections-and in which order-to process, based on their words and phrases) require having a representative document sample from each collection. These document samples have to be collected by querying the deep-web text collections, an expensive process that renders impractical the existing sampling approaches developed for other data scenarios. In this paper, we systematically study the space of query-based document sampling techniques for information extraction over the deep web. Specifically, we consider (i) alternative query execution schedules, which vary on how they account for the query effectiveness, and (ii) alternative document retrieval and processing schedules, which vary on how they distribute the extraction effort over documents. We report the results of the first large-scale experimental evaluation of sampling techniques for information extraction over the deep web. Our results show the merits and limitations of the alternative query execution and document retrieval and processing strategies, and provide a roadmap for addressing this critically important building block for efficient, scalable information extraction.

- Abstract
- Examines the effect of the information revolution on college and university libraries within the framework of the 3 interrelated concepts of transformation, reengineering and organizational behaviour. Advances in technology, specifically through the Internet, have had a major impact on how information is perceived and obtained and, consequently, the role of the academic librarian is evolving and expanding. Discusses 4 areas which must be addressed by academic librarians in the transition toward a reformed environment; strategic planning; educational aspects of the Internet; policy development; and management of electronic data. The library is a critical partner on academic campuses as an instigator and initiator of information literacy and a key player in accessing through networks that which is relevant

- Abstract
- The days of the traditional abstracting and indexing services are waning, as abstracts and bibliographic data become commodities. However, there are tremedous opportunities for those organizations willing to look beyond the status quo to the new possibilities enabled by the latest wave of advanced technologies. Those who own content need to focus on the delivery mechanisms and new markets that technology can provide. Features like automatic extraction of key concepts or names, collaborative filtering to help with trend analysis, and visualization techniques can take information past the retrieval stage and into the management area
