2. 11. Collaborative Network Security: Targeting Wide-area Routing and Edge-network Attacks

   Author : Rahul Gokulchand Hiran; Nahid Shahmehri; Niklas Carlsson; Olaf Maennel; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Collaboration; network security; BGP attacks; routing security; hijack;

   Abstract : To ensure that services can be delivered reliably and continuously over theInternet, it is important that both Internet routes and edge networks aresecured. However, the sophistication and distributed nature of many at-tacks that target wide-area routing and edge networks make it difficult foran individual network, user, or router to detect these attacks.

4. 12. 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. 13. 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.

6. 14. A study in integrating multiple biological data sources

   Author : Vaida Jakoniené; Patrick Lambrix; Nahid Shahmehri; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; information integration; databases; bioinformatics; biological data; BioTrifu; Computer science; Datavetenskap;

   Abstract : Life scientists often have to retrieve data from multiple biological data sources to solve their research problems. Although many data sources are available, they vary in content, data format, and access methods, which often vastly complicates the data retrieval process. READ MORE

7. 15. Integration of Biological Data

   Author : Vaida Jakonienė; Patrick Lambrix; Nahid Shahmehri; Michael Schroeder; Linköpings universitet; []
   Keywords : Datalogi; integration; grouping; databases; ontologies; biological data; ioinformatics; KitEGA; Datalogi; TECHNOLOGY; TEKNIKVETENSKAP;

   Abstract : Data integration is an important procedure underlying many research tasks in the life sciences, as often multiple data sources have to be accessed to collect the relevant data. The data sources vary in content, data format, and access methods, which often vastly complicates the data retrieval process. READ MORE
