”Adaptive Temporal Query Modeling” by Maria-Hendrike Peetz, Edgar Meij, Maarten de Rijke and Wouter Weerkamp is available here. We present an approach to query modeling that uses the temporal distribution of documents in an initially retrieved set of documents. Such distributions tend to exhibit bursts, especially in news-related document collections. We hypothesize that documents in those bursts are more likely to be relevant and update the query model with the most distinguishing terms in high-quality docu- ments sampled from bursts. We evaluate the effectiveness of our models on a test collection of blog posts.
”Result Disambiguation in Web People Search”, by Richard Berendsen, Bogomil Kovachev, Evi Nastou, Maarten de Rijke and Wouter Weerkamp is available here. In the paper we study the problem of disambiguating the results of a web people search engine: given a query consisting of a person name plus the result pages for this query, find correct referents for all mentions by clustering the pages according to the different people sharing the name. While the problem has been studied extensively, we discover that the increasing availability of results retrieved from social media platforms causes state-of-the-art methods to break down. We analyze the problem and propose a dual strategy where we distinguish between results obtained from social media platforms and those obtained from other sources. In our dual strategy, the two types of documents are disambiguated separately, using different strategies, and their results are then merged. We study several instantiations for the different stages in our proposed strategy and manage to achieve state-of-the-art performance.
