    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
    Electronic news has long held the promise of personalized and dynamic delivery of current event new items, particularly for Web users. Although wlwctronic versions of print news are now widely available, the personalization of that delivery has not yet been accomplished. In this paper, we present a methodology of associating news documents based on the extraction of feature phrases, where feature phrases identify dates, locations, people and organizations. A news representation is created from these feature phrases to define news objects that can then be compared and ranked to find related news items. Unlike tradtional information retrieval, we are much more interested in precision than recall. That is, the user would like to see one or more specifically related articles, rather than all somewhat related articles. The algorithm is designed to work interactively the the user using regular web browsers as the interface
