This study proposes novel hybrid social network analysis and collaborative filtering approach to enhance the performance of recommender systems. The proposed model selects subgroups of users in Internet community through social network analysis (SNA), and then performs clustering analysis using the information about subgroups. Finally, it makes recommendations using cluster-indexing CF based on...

This paper explores a variety of strategies for understanding the formation, structure, efficiency, and vulnerability of water distribution networks. Water supply systems are studied as spatially organized networks for which the practical applications of abstract evaluation methods are critically evaluated. Empirical data from benchmark networks are used to study the interplay between network s...

This paper proposes the integration of two systems engineering analysis tools, the Design Structure Matrix (DSM) and Network Analysis (NA), to study task interactions in a Product Development Process (PDP). The DSM is a matrix-based systems engineering tool that analyzes task sequences to improve PDP execution. Using NA metrics to measure properties of information flow helps to identify importa...

to describe the rheological behavior of polymer blends using emulsionbased (palierne theory) as well as micromechanical models (coranapproach), two immiscible polymeric blend systems of poly(trimethylene terephthalate) (ptt)/polyamide-12 (pa12) and ptt/polyethylene (pe) having different levels of molecular interactions were investigated as model systems. the role of interfacial interactions, vi...

A key impact of organizational systems and new information technologies is that they enable new organizational forms the structural features or patterns of relationships and information flows of an organization. Consequently, research on organization systems can benefit from methods that are explicitly directed toward describing and measuring organizational forms and structures. This article pr...

At the leading edge of Artificial Intelligence, machine learning game applications use a combination of various algorithms and different types of information. Searching the large space of solutions in depth leads to better solution. In checker board game next move of disc is important to defeat the opponent. Different selection strategy can be employed to select best next move. In this paper, w...

Evidently, based on studies which have been conducted over the years, there exist lots more complexity than technical in the development and implementation of information systems in organisations. The complex issues are socio-technical in nature, which require a refresh examination, from social context, if different results are to be achieved. Some of the complexities which are encountered incl...
