The paradigm of grid computing has been successfully applied in the domain of computationally-intensive applications supporting scientific research using server-class computers interconnected by wired network The users of the existing and growing number of wireless mobile devices often demand more computational power than their devices can currently provide. We propose using the computational grid paradigm to build a problem-solving environment for wireless mobile devices.

This paper proposes the FULL-COVERAGE summarizer: an efficient, information retrieval oriented method to extract non-redundant sentences from text for summarization purposes. Our method leverages existing information Retrieval technology by extracting key-sentences on the premise that the relevance of a sentence is proportional to its similarity to the whole document. We show that our method can produce sentence-based summaries that are up to 78% smaller than the original text with only 3% loss in retrieval performance.

Latent semantic indexing is a linear data reduction technique used in informational retrieval applications. The method of principal components is a popular linear data reduction technique that has been used in many applications. In this paper how the principal components method is used in information retrieval is presented, and how the latent semantic indexing is related to the principal component method is shown. Two experiments of monolingual and multilingual searches are described to show the feasibility of the method of principal components in information retrieval.

Personalization in education is supposed to be the answer to enhanced learning. Adaptive hypermedia (AH) is a means to this end. However, authoring of AH is still complicated This paper presents a system that tries to tackle this problem, by allowing leveled authoring of the adaptive behavior of AH, for beginner authors as well as advanced authors. This approach allows authors to implement their own conceptions about instructional strategies, aimed at, e.g., specific learning styles.

Grid computing is a major research area with increasing impact on the business world. Substantial work has been spend on improving the grid middleware but the gap between the high expectations and available real-life grid applications is still remarkable. There is a significant emerging risk of creating a new hype which may result in disillusion and disappointment. Therefore, this paper emphasises the urgence of providing reliable grid-based solutions -- regardless of their scientific or commercial domain in order to get grid computing to a mature state with wide-spread acceptance. An application prototype for editing and modelling grid workflows for semiprofessionals - as part of an approach for solving this problem - and a grid job example are described.

A new technique for optimally encoding a given source statistical properties of which are described by the first-order model is introduced. The calculation of codeword lengths is based on construction of a new source with statistics that is determined by the consecutive redistribution of the probabilities of symbols in accordance with their original probabilities at each stage of the encoding. The proposed method performs equally well for different orders of symbol probabilities. While codewords are generated by a, separate combinatorial procedure, the overall computational cost of the proposed method is lower than that for the Huffman code.

In order to achieve TV program group recommendation, an approach based on fuzzy clustering is proposed for program classification in this paper. This paper firstly describes the XML based program description metadata representation, in which both textual and symbolic information is included. Secondly it presents the program feature extraction and presentation method. A program is defined as two vectors, one is based on term statistics implying what the program is about, and the other reflects broadcasting characteristics of the program. Then the classifying approach based on fuzzy clustering is proposed. The approach goes: normalizing original data, building fuzzy similarity matrix, and then clustering. The final fuzzy similarity matrix is constructed by combining two fuzzy similarity matrices calculated from two different aspects.

The new economy is the result of the information revolution that promotes the emergence of networked, ubiquitous and collaborative service provision. Furthermore, the globalisation of trade has increased the number of competitors, driving the need for federated and networked business models. In this paper we argue that next generation ASP models could benefit from the use of the Grid. We describe a Grid-enabled architecture for coordinated resource sharing and problem solving in dynamic, multi-institutional ASP vendors.

New advancement in FPGA-DSP technology demands a new number system as well as a new data treatment that best utilizes the strengths and avoid the shortcomings of the new technology. To achieve this goal, here we introduce a customized floating-point number system that it can be reformatted as a fixed-point number when needed. In addition, a scheme is, proposed for the use of both formats in DSP applications, such as in digital filter design.

AI techniques have been applied in games since the beginning of the field. Fuzzy measures and fuzzy integrals, a powerful tool for decision making, have potentiality in games for the evaluation of strategies. In this paper we will explore the use of such soft computing techniques and show their interest in decision making and modeling auctions. The paper describes the role of fuzzy measures and integrals in decision making and reviews some computational aspects that are important for the application of such methods in real applications. The paper also gives a short overview on the methods for learning the parameters for these integrals from examples.
