In many governments and private institutions, one of the major tasks is to select the best project proposals for allocating the fund. These funding organizations select the proposals by submitting them to the reviewers for review. Manual process is too difficult when the number of projects is more. The earlier models introduced ontology based Text mining methods to cluster the proposals of any language...
Document classification is critical to optimize information retrieval tasks, especially over the web. In this environment, the open domain nature and growing volume of available data remain a challenge for the classification task. In this paper, we deal with these problems by only using knowledge resources. Our approach relies on concepts instances derived from the document and an open domain knowledge...
In automated multi-attribute negotiation, negotiation agent can get a better deal by using heuristic methods to make effective tradeoff or concession between different attributes. In this paper, we proposed a multi-attribute negotiation model based on internal factors argumentation which allows exchanging private information as argumentation, and then can reach ideal results without complex computation...
In many scientific disciplines, and in biomedicine in particular, researchers rely on ontologies to enable them to annotate and integrate their data. These ontologies are living and constantly evolving artifacts and the ontology authors must rely on their user community to ensure that the coverage of the ontologies is sufficient for annotations and other tasks for which users deploy the ontologies.
This article aims to develop several aspects of the current problems associated with the design of decision support systems of the type ODSS (Organisational Decision Support System). However, the design of a decision-making tool must go through a crucial phase and upstream which is the formalization of the process of decision making. Among the available models for the implementation of a decision...
Argumentation-based approach to negotiation, which allows agents to exchange additional information or argue their beliefs and other mental attitudes during the negotiation process, is gaining increasing popularity for its potential ability to overcome the limitations of conventional approaches. Most existing argumentation-based negotiation mechanisms are logic or rule-based and provide a formal or...
For a successful communication, autonomous entities (e.g. agents, web services, peers) must reconcile vocabulary used in their ontologies. The result is a set of mappings between ontology entities. Since each party might have its own perspective about what are the best mappings, conflicts will arise. Toward a mapping consensus building between information exchanging parties, this paper proposes an...
The first Natural Language Interfaces to Databases were built and designed for specific domains, and their customization processes implied source code manipulation. Open systems and database inter-operability enabled these interfaces to be independent of the operating system and database management system, and the separation of the knowledge base from the translation process allowed for domain portability...
IT governance planning is the first step of IT governance implementation. There are many related standards and frameworks for IT governance implementation, such as COBIT, ITIL and ISO 27002. In order to plan and design a proposal for IT governance implementation according to the company's IT governance requirements, ldquoIT process ontologyrdquo is introduced to model the knowledge of IT process,...
In this paper, we propose a set of semantic cohesion metrics for ontology measurement, which can be used to assess the quality of evolving ontologies in the context of dynamic and changing Web. We argue that these metrics are stable and can be used to measure ontology semantics rather than ontology structures. Measuring ontology quality with semantic inconsistencies caused by ontology evolutions,...
This work shows a conceptual model required for natural interaction, that is, imitating human behavior through interaction. This sort of Ontology is characterized by a set of services it should provide, for which both domain knowledge and reasoning mechanisms should be attained. However, special requirements and tasks for which this model is intended force a complete analysis and the design of an...
One of the possibilities for improving decision processes, and the knowledge management across interacting organizations is to explore successful past experiences. Case-based reasoning (CBR) is a problem solving strategy which is based on the reuse of past solutions (cases) to address new problems. Ontologies are a means to facilitate sharing and reuse of bodies of knowledge across organizations and...
As ubiquitous virtual reality (U-VR) systems become more and more popular and several systems coexist all together, sharing events between them in order to improve the user experience and increase their scope and functionality will be mandatory. Since U-VR systems have a dynamic and decoupled nature, and they have their own event model, we propose in this paper a semantic publish/subscribe infrastructure...
We present a Web system architecture using ontologies to improve the behavior of the system from the performance viewpoint. Since Web system performance indexes depend on state and parameter values on runtime period, the proposed system configuration will change during this period. In order to perform this change, the Web system is monitorized and gathered information stored into a knowledge base...
