ABSTRACT:
The aim of the ROBUST project is to analyze online communities with a business background in order to allow for a better understanding and management of these communities. This aim entails several challenges set in the field of information retrieval. In this talk I will give a brief introduction into the project and then focus in more detail on two quite different challenges that have been dressed in the context of ROBUST: Retrieval on social media and on linked data. The dynamics of social media imply new needs regarding the assessment of content quality and the notion of relevance. Here I will address the concept of "Interestingness" as a metric for assessing content quality in a microblogs. A quite different challenge underlies retrieval tasks over linked data. The linked data movement promotes the distributed publication of semantic data on the web. Schema extraction is one solution we are currently investigating to narrow the gap between document retrieval and semantic retrieval.
