This paper deals with the problem of building a common knowledge body for a set of domain ontologies in order to enable their sharing and integration in a collaborative framework. We propose a novel hierarchical algorithm for concept fuzzy set representation mediated by a reference ontology. In contrast to the original concept representations based on instances, this enables the application of ...

Ontologies are a crucial tool for formally specifying the vocabulary and the concepts of agent platforms, so, to share information, agents that use different vocabularies must be able to translate data from one ontological framework to another. The treatment of uncertainty plays a key role in the ontology mapping, as the degree of overlapping between concepts can not be represented logically. T...

One of the major challenges in modeling a real-world domain is how to effectively represent uncertain and incomplete knowledge that domain. Several techniques for representing uncertainty ontologies have been proposed with some lacking provision vague inference. The classical tableaux-based algorithm does not provide flexibility reasoning over such ontologies. However, several extensions cope f...

Word based searches for relevant information from texts retrieve a huge collection and burden the user with information overload. Ontology based text information retrieval can perform concept-based search and extract only relevant portions of text containing concepts that are present in the query or those that are semantically linked to query concepts. While these systems have better precision ...

Automatic ontology alignment tools perform matching between the concepts of two ontologies and provide a similarity measure for each pair of aligned concepts. However, none of the existing tools are perfect and multiple alignment tools produce varying similarity measures for a certain alignment. Also, the similarity measures provided by an alignment may not be helpful enough for indicating the ...

Information and knowledge are critical resources in operating and maintaining industrial process plants. The basis for the required knowledge repository is created at the design stage and extended after the hand-over of design data with modifications, maintenance histories and operational experiences. It is in the common interest of plant owners, engineering contractors and equipment and materi...

The Semantic Web has resulted in a wide range of information (e.g., HML, XML, DOC, PDF documents, ontologies, interfaces, forms, etc.) being made available in semantic queries, and the only requirement is that these are described semantically. Generic Web interfaces for querying databases (such as ISQLPlus ©) are also part of the Semantic Web, but they cannot be semantically described, and they...

Classification based on fuzzy logic techniques can handle uncertainty to a certain extent as it provides only the fuzzy membership of an element in a set. This paper implements the extension of fuzzy logic: Neutrosophic logic to handle indeterminacy, uncertainty effectively. Classification is done on various techniques based on Neutrosophic logic i.e. Neutrosophic soft set, rough Neutrosophic s...

– Systems that are integrated with recommendation features to support decision processes can provide a more personalized and proactive retrieval experience for users to choose among retrieval alternatives and subsequent refinement of choices. Many real-world systems call for autonomous intelligent agents acting in the face of uncertain knowledge and limited computational resources. This paper e...

Fulfilling needs through internal and external resources is a key business requirement. To better enable this, description of both needs and resources, using a common domain language is required. Using techniques from Social Network Analysis (SNA) this paper describes a SENSUS-based methodology which generates domain ontology that can provide the breadth and depth of coverage required for autom...
