Organizations of today are becoming ever more focused on their business processes. This has resulted in an increasing interest in business process patterns, which can be used in order to understand where from one can adopt best practices, or how to build computer systems supporting business processes. However, to fully exploit patterns, they need to be defined in a structured, and even formal w...

We introduce a methodology for obtaining inventories of error results for families of numerical dense linear algebra algorithms. The approach for deriving the analyses is goal-oriented, systematic, and layered. The presentation places the analysis side-by-side with the algorithm so that it is obvious where roundoff error is introduced. The approach supports the analysis of more complex algorith...

Contemporary pervasive computing environments demand mechanism for coherently addressing high-level user needs despite changing availability of resources. We propose the formalization of goals as the semantic basis for this mechanism, and sketch a system architecture that separates policy-rich goals-level planning code from a policy-neutral component assembly model.

A major drawback of current e-learning systems is that they are too disconnected from learner’s learning preferences and learning goals. There has been a high demanding for learner centric e-learning systems. Research on personalized e-learning is emerging in recent years. However, most of the current research is focused on user profile modeling, and learning styles research, etc. In this paper...

Many search engines help users to refine their search queries by showing a number of search suggestions, in addition to the search results. These suggestions can be used as queries in the next step of the search process. In this work we present a method to classify automatically the goal of a user as navigational (finding one specific web site), ‘hot’ (finding information that has recently beco...

Goal-oriented requirements engineering methodologies have been investigated for more than a decade, aiming at better supporting requirements engineering. They help elicit users’ requirements, deal with stakeholders’ goals and strategic dependencies among them. Moreover, they allow representing alternative solutions so that stakeholders and developers can negotiate and choose the one that meets ...

The development of high-quality software or software-intensive systems requires custom-tailored process models that fit the organizational and project goals as well as the development contexts. These models are a necessary prerequisite for creating project plans that are expected to fulfill business goals. Although project planners require individual process models custom-tailored to their cons...

Goal-oriented Behaviour for Intelligent Game Agents Ying Ying She, Ph.D. Concordia University, 2011 This thesis concerns our innovation in game AI techniques, mainly game agents’ modeling, planning and learning. The research topic involves the development of a game design software — Gameme. Our work mainly focus on the development of the core AI module. In this thesis, after discussing the syst...

In scientific and engineering contexts, physical systems are represented by mathematical models, characterized by a set of parameters. The inverse problem arises when the parameters are unknown and one tries to infer these parameters based on observations. Solving the inverse problem can require many model simulations, which may be expensive for complex models; multiple models of varying fideli...

This paper suggests a possible infrastructure that can be used to build a cognitive architecture, combining several principles that appeared through evolution. Anticipation, regulation and coordination of interactive processes are used to produce goal-oriented behaviors, illustrated by a navigation application. Implications of the model for the phylogenesis to ontogenesis transition are discuss...
