2. 1. Integration of Ontology Alignment and Ontology Debugging for Taxonomy Networks

   Author : Valentina Ivanova; Patrick Lambrix; Nahid Shahmehri; Eero Hyvönen; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ontology; ontology engineering; ontology alignment; ontology debugging;

   Abstract : Semantically-enabled applications, such as ontology-based search and data integration, take into account the semantics of the input data in their algorithms. Such applications often use ontologies, which model the application domains in question, as well as alignments, which provide information about the relationships between the terms in the different ontologies.

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. 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

6. 4. Dealing with Missing Mappings and Structure in a Network of Ontologies

   Author : Qiang Liu; Patrick Lambrix; Nahid Shahmehri; Henrik Eriksson; He Tan; Heiner Stuckenschmidt; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ontology; Ontology Engineering; Ontology Alignment; Ontology Debugging; Information technology; Informationsteknik;

   Abstract : With the popularity of the World Wide Web, a large amount of data is generated and made available through the Internet everyday. To integrate and query this huge amount of heterogeneous data, the vision of Semantic Web has been recognized as a possible solution. One key technology for the Semantic Web is ontologies. READ MORE

7. 5. Aligning and Merging Biomedical Ontologies

   Author : He Tan; Patrick Lambrix; Nahid Shahmehri; Bo Servenius; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ontologies; Ontology engineering; Biomedical ontologies; Ontology alignment; Ontology alignment; Ontology merging; Information technology; Informationsteknik;

   Abstract : Due to the explosion of the amount of biomedical data, knowledge and tools that are often publicly available over the Web, a number of difficulties are experienced by biomedical researchers. For instance, it is difficult to find, retrieve and integrate information that is relevant to their research tasks. READ MORE
