This e-book 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 equipped in topical sections on collaborative filtering and suggestion, assisting net groups, multi-agent structures, delicate computing tools, textual content processing and semantic internet, net details retrieval, and categorization and rating.

Programming Data-Driven Web Applications with ASP.NET

Programming Data-Driven net functions with ASP. internet presents readers with a pretty good realizing of ASP. internet and the way to successfully combine databases with their sites. the most important to creating details immediately to be had on the net is integrating the website and the database to paintings as one piece.

Contemporary Issues in Database Design and Information Systems Development

Database administration, layout, and data structures improvement have gotten an essential component of many enterprise purposes. modern concerns in Database layout and data structures improvement gathers the newest improvement within the quarter to make this the main up to date reference resource for educators and practitioners alike.

Trends in Interactive Visualization: State-of-the-Art Survey

This certain, multi-disciplinary quantity offers an perception into an energetic and very important zone of analysis – Interactive Visualization. Interactive Visualization allows the improvement of latest clinical thoughts to view facts, and to take advantage of interplay features to interrogate and navigate via datasets and higher speak the consequences.

Perspectives on Content-Based Multimedia Systems

Multimedia facts comprising of pictures, audio and video is changing into more and more universal. The lowering charges of customer digital units equivalent to electronic cameras and electronic camcorders, in addition to the benefit of transportation facilitated through the net, has result in an exquisite upward push within the volume of multimedia info generated and dispensed.

The proposal is enabled as a multi-agent system (MAS) where agents reason based on ontologies and direct event notification trough different channels or devices. 1 Introduction Nowadays web technology has become one of the most important infrastructures for supporting diverse communities; it may be because the Web allows ubiquitous access in a simple way thanks to the HTTP protocol and its addressing scheme [1], which in turn had foster its growth and had make possible the emergence of web communities.

Most TV programs are only available at the moment of broadcast. For this reason, we combine both measures into the global mean absolute error (gmae); it is the same as mae, but when a prediction technique or strategy cannot make a prediction the default value zero is assumed as the prediction. The lower the gmae the better the accuracy1. 1 Accuracy presented in this paper is based on a rating scale from -1 to +1, where -1 indicates a very strong negative interest and +1 a very strong positive interest; 0 indicates a neutral or indifferent interest.

Rule-based systems are very fast and scalable because they are model based. Since CBR is memory based, the speed of CBR-based strategies depends on the size of the case-bases. In some systems, limiting the size of the case-bases not only improves speed and makes the system more scalable, it can also improve the accuracy of a CBR-based prediction strategy. However, more research is needed to determine under which conditions improved accuracy can be expected with limited case-base sizes. All things considered, we conclude that CBR can indeed be used to create prediction strategies for hybrid recommender systems.
