- 925 sameAs 925.
- 925 abstract "The World Wide Web (WWW) now is widely used as a universal medium for information exchange. Semantic interoperability among different information systems in the WWW is limited due to information heterogeneity problem. Ontologies have been suggested as a way to solve this problem. Given that no universal ontology exists for the WWW, work has focused on finding semantic correspondences between similar elements of different ontologies, i.e., ontology mapping. Ontology mapping can be done either by hand or using automated tools. Manual mapping becomes impractical as the size and complexity of ontologies increases. Fully or semi-automated mapping approaches have been examined by different research studies, e.g., analyzing linguistic information of elements in ontologies, treating ontologies as structural graphs, applying heuristic rules to look for specific mapping patterns and machine learning techniques. This paper proposes a new generic and scalable ontology mapping approach, which takes advantage of propagation theory, information retrieval technique and artificial intelligence model to solve ontology mapping problem. The major procedures of the proposed approach are profile enrichment, profile propagation, IR-based profile mapping and the interactive activation network based constraints satisfaction. The profile enrichment builds a profile for each element in the ontologies, and thus enriches its information. The profile propagation exploits the neighboring information of each element by passing the profile of the ancestors, descendants or siblings of the element to the profile of itself, with different weights. The IR-based profile mapping process compares the cosine similarity of elements’ profiles in a vector space model. Finally the interactive activation network is integrated to deal with the constraints satisfaction problems in the context of ontology mapping.".

- 935 sameAs 935.
- 935 abstract "We propose a framework to model negotiations among agents in scenarios withfully incomplete information. We address multi-issue bilateral negotiations, where issues are expressed and related to each other via an OWL ontology. In particular we use OWL DL sub-language - as it is the "official language" of the Semantic Web communities - and exploit its formal semantics based on the Description Logic SHOIN(D). Agents goals are expressed through OWL-DL as (complex) concept expressions, and the worth of goals as weights over concepts. We adopt a very general setting with incomplete information by letting agents keep both goals and worths of goals as private information. Moreover we propose a framework through which agents can negotiate and reach an agreement. Agents, according to the protocol, can pursue different sets of strategies, depending on their type.".

- 940 abstract "Our research explores the possibilities for factoring culture into user models, working towards cultural adaptivity in the Semantic Web. The aim is to automate the localization process by acquiring details about an individual’s cultural background. The paper shows how we have based our approach on research findings from related fields, outlining the connection between the cultural user and domain model ontologies, and a test environment. Furthermore, we describe a preliminary plan of how to validate our cultural user model by comparison to our previous experience in the manual adaptation of imbuto.".

- 945 sameAs 945.
- 945 abstract "Only few well-maintained domain ontologies can be found on the Web. The reasons for the lack of useful domain ontologies include that (1) informal means to convey intended meaning more efficiently are used for ontology specification only to a very limited extent, (2) many relevant domains of discourse show a high degree of conceptual dynamics, (3) ontology representation languages are hard to understand for the majority of (potential) ontology users, and (4) the community does not have control over the ontology evolution. In my thesis, on which I have been working for 9 months, I propose to (1) base a methodology for community-grounded ontology building on the culture and philosophy of Wikis by giving users who have no or little expertise in ontology engineering the opportunity to contribute in all stages of the ontology lifecycle and (2) exploit the combination of human and computational intelligence to discover and resolve inconsistencies and align lightweight domain ontologies. The contribution of my thesis is a methodology for community-grounded building and evolution of lightweight domain ontologies.".

- 950 abstract "Unsatisfactory performance of ontology mapping methods on many tasks seems to indicate the need for employing some background knowledge. My PhD work focuses on exploiting pattern-like structures for this purpose. Design patterns are related to different styles of modelling ontology structure and/or naming of concepts. On the other hand, mapping patterns emerge as result of the mapping process. Preliminary results and schedule of future work are presented.".

- 955 abstract "This paper gives an outline of my PhD thesis which describes the integration of managing uncertainty into ontology mapping. Ontology mapping is one of the most important tasks for ontology interoperability and its main aim is to find semantic relationships between entities (i.e. concept, attribute, and relation) of two ontologies, However, in the process of mapping, uncertainty and incompleteness of semantics in the syntactic representation and description of relations between entities in ontologies will lead to imprecise results. If we want to obtain better results, it becomes more significant for the ontology mapping to be able to deal with uncertainty.".
