This ebook constitutes the refereed complaints of the second one foreign internet Intelligence convention, AWIC 2004, held in Cancun, Mexico, in might 2004. The 22 revised complete papers awarded have been rigorously reviewed and chosen from fifty two submissions. The papers are geared up in topical sections on collaborative filtering and advice, assisting net groups, multi-agent structures, tender computing equipment, textual content processing and semantic internet, net details retrieval, and categorization and score.

Present learn into formal equipment for layout is gifted within the papers during this quantity. due to the complexity of VLSI circuits, assuring layout validity ahead of circuits are synthetic is critical. The target of analysis during this sector is to enhance tools of enhancing the layout technique and the standard of the ensuing designs.
Development on common use of the C++ programming language in and schooling, this publication presents a broad-based and case-driven learn of information constructions -- and the algorithms linked to them -- utilizing C++ because the language of implementation. This ebook areas detailed emphasis at the connection among info buildings and their algorithms, together with an research of the algorithms' complexity.

Using distances as weights is difficult due to the non-fixed upper level of distance; the maximum possible distance is unknown or may differ per distance measure. However, similarity measures are in the range of [0, 1] , one means that two cases are exactly the same and zero means that two cases are completely different. As traditional CBR systems use distances, it is necessary to convert distances into similarities. We explored three types of conversion functions for the conversion of distance to similarity: linear functions, sigmoidal functions and the inverted function.
For example, in two situations A and B, a validity indicator of social filtering indicates that there are 40 similar users that have rated the item for which a prediction is necessary; however, in situation A, early in the system, the similarity of these 40 users is based on less rated items by each user than in the later situation B; hence the probability that social filtering provides an accurate prediction is higher in situation B than in A. However, the improved effect of limited case-base sizes may also be influenced by the time-based characteristic of TiV.
5 Towards a New Web Document Entity Because the GAA is interested in the evolution of the different interrelated entities that compose the author’s self-adaptive cooperative environment, the management of them constitutes an unavoidable endeavor. Thus, we propose an elaborated notion of Web document entity that can be considered as a closure and a container of resources. This notion is designed to satisfy the following GAA’s requirements: Containment consistency- a Web document entity should be treated as a container of all resources needed and used by the document.
