Zásady pro vypracování

One of the most important benefits of Linked Data [4] is the possibility to integrate data from multiple sources. This poses new challenges in data fusion [3], quality assessment [5], and provenance tracking [6].

The topic of the thesis is a data fusion (conflict resolution) component that would enable users to integrate and filter RDF data, estimate their quality and obtain provenance information. Data fusion component proposed may be executed at query time according to policies given by data consumers [2,5] or offline (batch mode). Data fusion will be implemented as a standalone component applicable to data represented in RDF and also deployed as part of the ODCleanStore project [1]. The thesis will also provide experimental evaluation of the proposed data fusion component and provide comparison of the proposed data fusion technique with existing data fusion techniques in relational databases.
