The increasing volume of semantic data on the Web has enabled many intelligent applications, but also raises new research challenges. In this talk, I will present our recent research on semantic data retrieval. I will begin with the task of retrieving semantic associations (aka complex relationships) that connect a set of entities in a user query. This kind of a task represents a class of information needs that are not well supported by traditional Web search but now can be met with semantic data. To solve the problem, I will present efficient search algorithms, novel ranking measures, and effective summarisation and presentation of search results. We will also discuss the more general problem of semantic data summarisation.
