Discusses the cost of constructing a hypertext database and suggests cost forecasting approaches that can be used to determine whether organizations can internally fund a hypertext database, or whether producers can afford to market hypertext databases. Production costs in differing hypertext strategies are also compared. (27 references) (LRW)

In World Wide Web indexing: (1) the creation process is automated; (2) the indexes are merely descriptive, not analytical of document content; (3) results may be sorted differently depending on the search engine; and (4) indexes link directly to the resources. This article compares the indexing methods and querying options of the search engines…

Discussion of hypermedia systems focuses on a comparison of two types of adaptive algorithm (genetic algorithm and neural network) in clustering hypermedia documents. These clusters allow the user to index into the nodes to find needed information more quickly, since clustering is "personalized" based on the user's paths rather than…

Investigates one component of a Web site--the index structure, comparing the effectiveness and efficiency of 20 subjects who used one index and three experimental variants to complete five tasks. Findings indicate that a hypertext index with multiple access points for each concept, all linked to the same resource, led to greater effectiveness and…

This survey of 1037 World Wide Web objects on polymer chemistry collected by four search engines (AltaVista, Lycos, Excite, Webcrawler) examined document information and use of meta fields, images, and chemical names. Found that the use of meta fields was not widespread and that knowledge of meta fields in HTML varied among Web object creators.…

The IADIS CELDA 2012 Conference intention was to address the main issues concerned with evolving learning processes and supporting pedagogies and applications in the digital age. There had been advances in both cognitive psychology and computing that have affected the educational arena. The convergence of these two disciplines is increasing at a…
