Title: Faceted and Expert Search in the Enterprise

Abstract:

Enterprise Search problems recently received a considerable amount of attention from academia, mainly due to the increasing demand in industrial solutions supporting various search tasks in intranets. In this lecture I will give the research perspective on two core aspects of search in the Enterprise: Faceted and Expert search. I will demonstrate typical search scenarios, visualization approaches and ranking techniques. In the first part, I will overview the ways to support faceted search in typical cases, from easiest to hardest: with the availability of structured or unstructured document metadata and with no document metadata available. In the second part, I will talk about the latest developments in expert finding, namely, language model and graph-based based methods. I will also show the ways to to acquire expertise evidence outside of the Enterprise.
