2. 1. Completion of Ontologies and Ontology Networks

   Author : Zlatan Dragisic; Patrick Lambrix; Nahid Shahmehri; Marco Kuhlmann; Fang Wei-Kleiner; Erhard Rahm; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; knowledge representation; ontology; ontology engineering; ontology debugging; ontology completion; ontology matching; description logics;

   Abstract : The World Wide Web contains large amounts of data, and in most cases this data has no explicit structure. The lack of structure makes it difficult for automated agents to understand and use such data. A step towards a more structured World Wide Web is the Semantic Web, which aims at introducing semantics to data on the World Wide Web. READ MORE

4. 2. Fostering User Involvement in Ontology Alignment and Alignment Evaluation

   Author : Valentina Ivanova; Patrick Lambrix; Nahid Shahmehri; Fabien Gandon; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Knowledge representation; ontology; ontology engineering; ontology debugging; ontology matching; ontology matching evaluation; user interfaces; human-computer interaction; large and high-resolution displays;

   Abstract : The abundance of data at our disposal empowers data-driven applications and decision making. The knowledge captured in the data, however, has not been utilized to full potential, as it is only accessible to human interpretation and data are distributed in heterogeneous repositories.

5. 3. Ontology Integration with Non-Violation Check and Context Extraction

   Author : Dan Wu; Anne Håkansson; Carl-Gustaf Jansson; Paul Johannesson; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ontology matching and integration; semantic and pragmatic matching; semantic techniques; context; ontology and rules; SRA - ICT; SRA - Informations- och kommunikationsteknik;

   Abstract : Matching and integrating ontologies has been a desirable technique in areas such as data fusion, knowledge integration, the Semantic Web and the development of advanced services in distributed system. Unfortunately, the heterogeneities of ontologies cause big obstacles in the development of this technique. READ MORE

6. 4. Context Knowledge Base for Ontology Integration

   Author : Dan Wu; Anne Håkansson; Carl-Gustaf Jansson; Jelena Zdravkovic; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; ontology integration; semantic and pragmatic integration; context; knowledge base; rules; SRA - ICT; SRA - Informations- och kommunikationsteknik;

   Abstract : Ontology integration is a process of matching and merging two ontologies for reasons such as for generating a new ontology, thus creating digital services and products. Current techniques for ontology integration, used for information and knowledge integration, are not powerful enough to handle the semantic and pragmatic heterogeneities. READ MORE

7. 5. Modeling and improving Spatial Data Infrastructure (SDI)

   Author : Ehsan Abdolmajidi; Institutionen för naturgeografi och ekosystemvetenskap; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Spatial Data Infrastructure; System Dynamics; Fuzzy Logic; Data integration; Pattern detection; Resource Description Framework RDF ; Ontology;

   Abstract : Spatial Data Infrastructure (SDI) development is widely known to be a challenging process owing to its complex and dynamic nature. Although great effort has been made to conceptually explain the complexity and dynamics of SDIs, few studies thus far have actually modeled these complexities. READ MORE
