    Abstract
    The increasing complexity of problems addressed by massively distributed information systems has led to the development of worldwide information systems, such as the WWW and Hyper-G. Presents a conceptual framework for those systems using a knowledge representation language, Telos, by concentrating on the semantics of their domains. The framework is developed and based on careful analysis and abstraction of those existing systems. By creating a rich and precise conceptual framework, provides a foundation for the specification and implementation of future universal information systems.

    Abstract
    Reviews the most common Internet search engines: AltaVista; Excite; InfoSeek; Lycos; HotBot and WebCrawler, focusing on the existing comparative studies of the search engines. Views the quality dimensions of the search engines, based on a SERVQUAL framework, in order to approach the problem from the users' viewpoint. Identifies and groups the most important quality expectations of users into 5 quality dimensions, using the SERVQUAL model: tangibles; reliability; responsiveness; assurance; and empathy
