An Informational Model for Cooperative Information Gathering
نویسنده
چکیده
A Cooperative Information Gathering system may be abstracted as three communicating models: an informational model (IM), an organizational model (OM) and a task model (TM). This paper focuses on the informational model describing the Universe of Discourse (UoD) and the users' subjects of interest. It presents a new way of looking at ontology as a super-topic. Then, ontology in our IM is not used only to help a CIG system to deal with the heterogeneities of information sources, but also to help it to capture the user’s subjects of interest.

Improving Fourth Graders’ Literary and Informational Comprehension Skills through Cooperation while Teaching and Learning
Considering the vast amount of information on fourth graders’ poor skills in reading comprehension, especially when reading literary and informational texts, and the general agreement on the teaching methods being the main culprit, it was decided to examine the use of the cooperative method of teaching reading as a possible solution for the said problem. A random sample of 100 fourth graders fr...
متن کاملA Distributed Problem Solving Approach to Cooperative Information Gathering
Introduction: The complexity of the modern information carrying landscape requires a sophisticated view in which information is acquired rather than simply retrieved; where the process must be dynamic, incremental, and constrained by resource limitations. Information Gathering (IG) is an activity involving pro-active acquisition of information, from possibly heterogeneous sources, in response t...
متن کاملA multi agent method for cell formation with uncertain situation, based on information theory
This paper assumes the cell formation problem as a distributed decision network. It proposes an approach based on application and extension of information theory concepts, in order to analyze informational complexity in an agent- based system, due to interdependence between agents. Based on this approach, new quantitative concepts and definitions are proposed in order to measure the amount of t...
متن کاملA Probabilistic Model of Action for Least-Commitment Planning with Information Gathering
AI planning algorithms have addressed the problem of generating sequences of operators that achieve some input goal, usually assuming that the planning agent has perfect control over and information about the world. Relaxing these assumptions requires an extension to the action representation that allows reasoning both about the changes an action makes and the information it provides. This pape...
متن کاملA society of cooperative agents on the information network: towards intelligent information gathering
In this paper, we propose a completely agent-based approach for Information Gathering on information network with a large number of distributed heterogeneous sources, such as Internet. Locating and accessing information in such a large distributed system which changes dynamically is challenging. Agentbased solution is most suitable in such situation. We rst review the drawbacks of existing non-...
