- 439 abstract "The novel practice of Open Innovation on the Web has imposed new challenges to known expert search approaches. At the same time, many potential sources of evidence about users' interest and expertise (e.g., research papers, blogs, activities) are becoming ubiquitously present as Linked Data. In this paper we present a research effort for suggesting the right way to search for potential Open Innovation problem solvers in Linked Data sources, by looking at the structure of available data sources. In addition, we seek to develop ways of suggesting domains of expertise that are in some way relevant to the domain of the Open Innovation problem, in order to enable a cross-domain solution transfer.".

- 440 sameAs 440.
- 440 abstract "When multiple ontologies are used within one application system, aligning the ontologies is a prerequisite for interoperability and unhampered semantic navigation and search. Various methods have been proposed to compute mappings between elements from different ontologies, the majority of which being based on various kinds of similarity measures. As a major shortcoming of these methods it is difficult to decode the semantics of the results achieved. In addition, in many cases they miss important mappings due to poorly developed ontology structures or dissimilar ontology designs. I propose a complementary approach making massive use of relation extraction techniques applied to broad-coverage text corpora. This approach is able to detect different types of semantic relations, dependent on the extraction techniques used. Furthermore, exploiting external background knowledge, it can detect relations even without clear evidence in the input ontologies themselves.".

- 441 abstract "This paper presents our work on supporting evaluation of integrity constraint issues in semantic web instance data. We propose an alternative semantics for the ontology language, i.e., OWL, a decision procedure for constraint evaluation by query answering, and an approach of explaining and repairing integrity constraint violations by utilizing the justifications of conjunctive query answers.".

- 442 sameAs 442.
- 442 abstract "SPARQL is the W3C Recommended query language for RDF. My current work aims at extending SPARQL in two distinct ways: (i) to allow a better integration of RDF and XML; and (ii) to define a query language for RDF extended with domain specific annotations. Transforming data between XML and RDF is a much required, but not so simple, task in the Semantic Web. The aim of (i) is to enable transparent transformations between these two representation formats, relying on a new query language called XSPARQL. On a different aspect, representing and reasoning with meta-information about RDF triples has been addressed by several proposals for representing time, trust and provenance. A common extension of RDF (and RDFS inferencing rules), capable of encompassing all these proposals, with a clearly defined semantics is much desirable. Building on top of Annotated RDF, we present such an extension and an extension of the SPARQL language capable of querying triples with annotations. An open research issue remains the possibility of unifying the two, currently independent, extensions of SPARQL.".

- 445 abstract "Web service composition (WSC) - loosely, the composition of web-accessible software systems - requires a computer program to automatically select, integrate, and invoke multiple web services in order to achieve a user-defined objective. It is an example of the more general task of composing business processes or component-based software. Our doctoral research endeavours to make fundamental contributions to the knowledge representation and reasoning principles underlying the task of WSC, with a particular focus on the customization of compositions with respect to individual preferences. The setting for our work is the semantic web, where the properties and functioning of services and data are described in a computer-interpretable form. In this setting we conceive of WSC as an Artificial Intelligence planning task. This enables us to bring to bear many of the theoretical and computational advances in reasoning about action and planning to the task of WSC. However, WSC goes far beyond the reaches of classical planning, presenting a number of interesting challenges that are relevant not only to WSC but to a large body of problems related to the composition of actions, programs, business processes, and services. In what follows we identify a set of challenges facing our doctoral research and report on our progress to date in addressing these challenges.".
