- Abstract
- Creates an open, metadata aware system for distributed, collaborative WWW indexing. The system has 3 main components: a harvester (for collecting information), a database (for making the collection searchable), and a user interface (for making the information available). all components can be distributed across networked computers, thus supporting scalability. The system is metadata aware and thus allows searches on several fields including title, document author and URL. Nordic Web Index (NWI) is an application using this system to create a regional Nordic Web-indexing service. NWI is built using 5 collaborating service points within the Nordic countries. The NWI databases can be used to build additional services

- 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
- 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
- Organizing and providing access to the resources an the Internet has been a problem area in spite of the availability of sophisticated search engines and other Software tools. There have been several attempts to organize the resources an the World Wide Web. Some of them have tried to use traditional library classification schemes such as the Library of Congress Classification, the Dewey Decimal Classification and others. However there is a need to assign proper subject headings to them and present them in a logical or hierarchical sequence to cater to the need for browsing. This paper attempts to describe an experimental system designed to organize and provide access to web documents using a faceted pre-coordinate indexing system based an the Deep Structure Indexing System (DSIS) derived from POPSI (Postulate based Permuted Subject Indexing) of Bhattacharyya, and the facet analysis and chain indexing system of Ranganathan. A prototype Software System has been designed to create a database of records specifying Web documents according to the Dublin Core and to input a faceted subject heading according to DSIS. Synonymous terms are added to the Standard terms in the heading using appropriate symbols. Once the data are entered along with a description and the URL of the web document, the record is stored in the System. More than one faceted subject heading can be assigned to a record depending an the content of the original document. The System stores the Surrogates and keeps the faceted subject headings separately after establishing a link. The search is carried out an index entries derived from the faceted subject heading using the chain indexing technique. If a single term is Input, the System searches for its presence in the faceted subject headings and displays the subject headings in a sorted sequence reflecting an organizing sequence. If the number of retrieved Keadings is too large (running into more than a page) the user has the option of entering another search term to be searched in combination. The System searches subject headings already retrieved and looks for those containing the second term. The retrieved faceted subject headings can be displayed and browsed. When the relevant subject heading is selected the system displays the records with their URLs. Using the URL, the original document an the web can be accessed. The prototype system developed in a Windows NT environment using ASP and a web server is under rigorous testing. The database and Index management routines need further development.
An interesting but somewhat confusing article telling how the writers described web pages with Dublin Core metadata, including a faceted classification, and built a system that lets users browse the collection through the facets. They seem to want to cover too much in a short article, and unnecessary space is given over to screen shots showing how Dublin Core metadata was entered. The screen shots of the resulting browsable system are, unfortunately, not as enlightening as one would hope, and there is no discussion of how the system was actually written or the technology behind it. Still, it could be worth reading as an example of such a system and how it is treated in journals.

- Proposes a new mechanism for implicitly specifying hyperlinks in HTML documents using indices. Indices maintain these key /a ttribute bindings over all or part of a document, and are used by browsers to create hyperlinks dynamically. Indices may also include bindings of other indices, in a hierarchical fashion. Indices are both simpler and more general than the current HTML hyperlink mechnisms.

- 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

- Abstract
- Purpose - The "photosharing" site Flickr is one of the most commonly cited examples used to define Web2.0. This paper aims to explore where Flickr's real novelty lies, examining its functionality and its place in the world of amateur photography. Several optimistic views of the impact of Flickr such as its facilitation of citizen journalism, "vernacular creativity" and in learning as an "affinity space" are evaluated. Design/methodology/approach - The paper draws on a wide range of sources including published interviews with its developers, user opinions expressed in forums, telephone interviews and content analysis of user profiles and activity. Findings - Flickr's development path passes from an innovative social game to a relatively familiar model of a web site, itself developed through intense user participation but later stabilising with the reassertion of a commercial relationship to the membership. The broader context of the impact of Flickr is examined by looking at the institutions of amateur photography and particularly the code of pictorialism promoted by the clubs and industry during the twentieth century. The nature of Flickr as a benign space is premised on the way the democratic potential of photography is controlled by such institutions. The limits of optimistic claims about Flickr are identified in the way that the system is designed to satisfy commercial purposes, continuing digital divides in access and the low interactivity and criticality on Flickr. Originality/value - Flickr is an interesting source of change, but can only be understood in the perspective of long-term development of the hobby and wider social processes. By setting Flickr in such a broad context, its significance and that of Web2.0 more generally can be fully assessed.

- Abstract
- A novel idea of media agent is briefly presented, which can automatically build a personalized semantic index of Web media objects for each particular user. Because the Web is a rich source of multimedia data and the text content on the Web pages is usually semantically related to those media objects on the same pages, the media agent can automatically collect the URLs and related text, and then build the index of the multimedia data, on behalf of the user whenever and wherever she accesses these multimedia data or their container Web pages. Moreover, the media agent can also use an off-line crawler to build the index for those multimedia objects that are relevant to the user's favorites but have not accessed by the user yet. When the user wants to find these multimedia data once again, the semantic index facilitates text-based search for her.

- Abstract
- The Digital Object Identifier (DOI) has been developed by the academic technical and medical publishing sectors to enable the management of access rights to information published electronically. The DOI system has evolved from the physical documentary unit identifiers developed in the 1970, physical and document logical unit identifiers developed in the 1980s and recently modified to meet the needs of electronic distribution. This experience is integrated into the standardization, currently in progress on the Internet network, of the identification of resources and their localization. The DOI system is potentially the object of an international standard as the ISBN and the ISSN have been

- Abstract
- Users move from one state (or task) to another in an information system's labyrinth as they try to accomplish their work, and the amount of time they spend in each state varies. This article uses continuous-time stochastic models, mainly based on semi-Markov chains, to derive user state transition patterns (both in rates and in probabilities) in a Web-based information system. The methodology was demonstrated with 126,925 search sessions drawn from the transaction logs of the University of California's MELVYL® library catalog system (www.melvyLucop.edu). First, user sessions were categorized into six groups based on their similar use of the system. Second, by using a three-layer hierarchical taxonomy of the system Web pages, user sessions in each usage group were transformed into a sequence of states. All the usage groups but one have third-order sequential dependency in state transitions. The sole exception has fourth-order sequential dependency. The transition rates as well as transition probabilities of the semi-Markov model provide a background for interpreting user behavior probabilistically, at various levels of detail. Finally, the differences in derived usage patterns between usage groups were tested statistically. The test results showed that different groups have distinct patterns of system use. Knowledge of the extent of sequential dependency is beneficial because it allows one to predict a user's next move in a search space based on the past moves that have been made. It can also be used to help customize the design of the user interface to the system to facilitate interaction. The group CL6 labeled "knowledgeable and sophisticated usage" and the group CL7 labeled "unsophisticated usage" both had third-order sequential dependency and had the same most-frequently occurring search pattern: screen display, record display, screen display, and record display. The group CL8 called "highly interactive use with good search results" had fourth-order sequential dependency, and its most frequently occurring pattern was the same as CL6 and CL7 with one more screen display action added. The group CL13, called "known-item searching" had third-order sequential dependency, and its most frequently occurring pattern was index access, search with retrievals, screen display, and record display. Group CL14 called "help intensive searching," and CL18 called "relatively unsuccessful" both had thirdorder sequential dependency, and for both groups the most frequently occurring pattern was index access, search without retrievals, index access, and again, search without retrievals.

- Abstract
- An exploratory research project was undertaken to understand how novice college students and Web savvy librarians initially envisioned the Internet and how these representations changed over time and with experience. Users' representation of the Internet typically contained few meaningful reference points excepting "landmarks" such as search sites and frequently visited sites. For many of the users, the representation was largely procedural, and therefore organized primarily by time. All novice users conceptualized search engines as literally searching the entire Internet when a query was issued. Web savvy librarians understood the limitations of search engines better, but did still expect search engines to follow familiar organizational schemes and to indicate their cataloguing system. Although all users initially approached the Internet with high expectations of information credibility, expert users learned early on that "anyone can publish." In response to the lack of clear credibility conventions, librarians applied the same criteria they used with traditional sources. However, novice users retained high credibility expectations because their exposure was limited to the subscription-based services within their college library. And finally, during an assigned search task new users expected "step by step" instructions and self-evident cues to interaction. They were also overwhelmed and confused by the amount of information "help" displayed and became impatient when a context appropriate solution to their problem was not immediately offered

- Abstract
- Argues that classification systems have an important role to play in knowledge organization in the new world electronic order. The natural language approach is not incompatible with the use of a classification system and classification has untapped potential as a multilingual switching language. Librarians must learn to present classification systems in a language understood by a general audience and promote them as general knowledge organization tools
