Abstract

The rapidly increasing volume and variety of electronic or digitized information sources and their accessibility worldwide, have brought to the surface new issues concerning intellectual property, the complexity of the related legal questions and application of legislative measures in real world situations. Attemps to define 'intellectual property' from different points of view; considers the different types with different 'strengths' of protection, and the underlying objectives of such protection. Discusses copyright and international treaties on intellectual property, what is protected and for how long, the concept of fair use and the role of organizations concerned with reproduction rights. Presents a brief overview of the intellectual property questions relating to electronic media: machine readable databases, the information resources on the Internet, and images; electrocopying and downloading of texts and images from networks; and the special nature and copyright problems of multimedia. Also considers moral rights and the need for and feasibility of establishing Electronic Copyright Management System (ECMS)

Abstract

The Internet gives access for blind and visually impaired users to previously unobtainable information via Braille or speech synthesis interpretation. This paper looks at how three search engines, AltaVista, Yahoo! and Infoseek presented their information to a small group of visually impaired and blind users and how accessible individual Internet pages are. Two participants had varying levels of partial sight and two Subjects were blind and solely reliant on speech synthesis output. Subjects were asked for feedback on interface design at various stages of their search and any problems they encountered were noted. The barriers to access that were found appear to come about by lack of knowledge and thought by the page designers themselves. An accessible page does not have to be dull. By adhering to simple guidelines, visually impaired users would be able to access information more effectively than would otherwise be possible. Visually disabled people would also have the same opportunity to access knowledge as their sighted colleagues.

Abstract

The literature of the evaluation of Internet search engines is reviewed. Although there have been many studies, there has been little consistency in the way such studies have been carried out. This problem is exacerbated by the fact that recall is virtually impossible to calculate in the fast changing Internet environment, and therefore the traditional Cranfield type of evaluation is not usually possible. A variety of alternative evaluation methods has been suggested to overcome this difficulty. The authors recommend that a standardised set of tools is developed for the evaluation of web search engines so that, in future, comparisons can be made between search engines more effectively, and that variations in performance of any given search engine over time can be tracked. The paper itself does not provide such a standard set of tools, but it investigates the issues and makes preliminary recommendations of the types of tools needed

Abstract

Four subjects - ecology, applied mathematics, sociology, and economics - were selected to assess whether there is a citation advantage between journal articles that have an open-access (OA) version on the Internet compared to those articles that are exclusively toll access (TA). Citations were counted using the Web of Science, and the OA status of articles was determined by searching OAIster, OpenDOAR, Google, and Google Scholar. Of a sample of 4,633 articles examined, 2,280 (49%) were OA and had a mean citation count of 9.04 whereas the mean for TA articles was 5.76. There appears to be a clear citation advantage for those articles that are OA as opposed to those that are TA. This advantage, however, varies between disciplines, with sociology having the highest citation advantage, but the lowest number of OA articles, from the sample taken, and ecology having the highest individual citation count for OA articles, but the smallest citation advantage. Tests of correlation or association between OA status and a number of variables were generally found to weak or inconsistent. The cause of this citation advantage has not been determined.
