— Agent-based modeling is one of the popular tools for analyzing complex socio-technical systems. Because of the complex nature of such systems a systematic methodology is required to guide the modeling process. By studying the existing methodologies in MAS we distinguished four major differences between MAS and ABM regarding goals, system scale and(More)
Acquiring new customers in any business is much more expensive than trying to keep the existing ones. Thus many prediction models are presented to detect churning customers. The objective of this paper was to improve the predictive accuracy and interpretability of churn detection. For this purpose, the application of the locally linear model tree (LOLIMOT)(More)
With the emergence of vast resources of information, it is necessary to develop methods that retrieve most relevant information according to the users needs. These retrieval methods may benefit from natural language constructs to boost their results by achieving higher precision/recall rates. In this attempt, we have used part of speech attributes of terms(More)

Agent-based modeling is one of the popular tools for analyzing complex social systems. To model such systems, social attributes such as culture, law and institutions need to implemented as part of the context of a MAS, independently of individual agents. In this paper, we present MAIA; a framework for modeling agent-based systems based on the Institutional(More)
With the emergence of Web service mashups, selecting the appropriate Web services from the vast amount of available services has emphasized the role of service discovery. In this research, we present a new way of enhancing Web services semantically using WordNet concepts (synsets). The important advantage of our solution is that it allows developers to(More)
A shared strategy is a social concept that refers to a type of behavioural pattern that is followed by a significant number of individuals although it is, prima facie, not associated with an obligation or a prohibition. E. Ostrom has argued in favour of the pertinence of social strategies for institutional design and evolution and proposed a(More)
