**Hidden Oversampling in Learning-to-Rank** **Hidden Oversampling in Learning-to-Rank**
The machine learning approaches to solve the problem of ranking in search engines rely on vast amounts of training data. Those training datasets contain duplicated documents that are unexpected in subsequent machine learning algorithms. We investigate the impact of that "hidden oversampling" to the produced rankings of the search engine.

**Vortragstitel** **Comparative Web Search Questions**
Inhaltliche Kurzbeschreibung in 2-3 Sätzen, wenn möglich in Englisch. Users ask comparative questions, i.e., questions asking to compare different items, not only on community question answering platforms like Yahoo! Answers, Quora, or StackExchange, but also submit as queries to search engines. Responses to such questions might be quite different from the simple ''ten blue links'' and could, for example, aggregate pros and cons of the different options as direct answers. We analyze such questions and propose methods to answering them.

**Vortragstitel** **Same Side Stance Classification**
Inhaltliche Kurzbeschreibung in 2-3 Sätzen, wenn möglich in Englisch. In recent years, the popularity of social media and online discussions has lead to a rise of pro and con argumentation for various topics. Still, since not all contributions in such online discussions clearly indicate a stance or polarity of the contribution, automatically identifying some post's stance (in social media platforms, etc.) could help readers quickly get an overview of a discussion similar to debating portals with pro/con arguments.
