“…Four different approaches to deal with ontologies interoperability are proposed in the literature: mapping, alignment, merge and integration 2 . Ontology mapping determines when two ontologies are semantically related at conceptual level, and how instances of the source ontology are transformed into instances of the target ontology according to its semantic associations, also providing mechanisms to transfer instances among them 36,26 . More oriented to deal with complementary ontologies, the alignment approach results in a mutual accordance, where two source ontologies become consistent and coherent, generating as a final result the two original ontologies separately, but with additional links between their equivalent terms.…”

Ontology matching for dynamic publication in semantic portals

Semantic portals are characterized for storing and structuring content according to specific domain ontologies. This content is represented through ontological languages, which enable not only adding semantic value to information treatment, but also inferring new knowledge from it. Publication in a semantic portal is typically done by instantiating its ontology, and this is often performed manually or through the use of specific forms. However, in order to keep portals constantly up-to-date, it is necessary to provide means for a more dynamic publication, integrating the portal content with information retrieved from different ontology-based sites on the same or on complementary domains. Reusing information from different ontologies requires specific and efficient mechanisms to align them, taking into account syntactical and semantical conflicts. This paper proposes an extension of the Crosi Mapping System, a matching mechanism which calculates similarities between ontologies. Some of its original algorithms have been enriched with additional functionality. This extension, named e-CMS, has been evaluated using the OAEI ontology alignment benchmark, and results show an increase of 69% in alignment precision when compared to the CMS original version. In order to illustrate its use, the e-CMS strategy was applied to SiGePoS, a System for Generating Semantic Portals. The semantic module, one of the system components, implements the alignment mechanism between ontologies, which is performed by the e-CMS.

“…Such "stitching" would require a degree of semantic integration or mapping of different ontologies (e.g., Akahani, Hiramatsu, & Satoh, 2003;Gašević & Hatala, 2005Silva & Rocha, 2003). But as well as the linking of discrete ontologies generated by different communities so that they can reference and communicate with each other, there will be an increasing need to come to terms with a diversity of competing ontological perspectives within communities requiring negotiation to establish, and record, parameters of agreement and disagreement.…”

“…Proposed typical approaches include ontology mapping and integration [2,48], schema manipulation [9,17], and interpretation [23]. Nevertheless, there is no good generic and intelligent ontology mapping solution working across domains and applications over the Web at this moment [16].…”

Towards integrating semantics of multi-media resources and processes in e-Learning

Internet-based e-Learning has experienced a boom and bust situation in the past 10 years [32]. To bring in new forces to knowledge-oriented e-Learning, this paper addresses the semantic integration issue of multimedia resources and learning processes with theoretical learning supports in an integrated framework. This paper proposes a context-mediated approach that aims to enable semantic-based inter-operations across knowledge domains, even across the WWW and the Semantic Web [8]. The proposed semantic e-Learning framework enables intelligent operations of heterogeneous multi-media contents based on a generic semantic context intermediation model. This framework supports intelligent e-Learning with a knowledge network for knowledge object visualization, an enhanced Kolb's learning cycle [31] to guide learning practices, and a learning health care framework for personalized learning.
