Coling 2014 paper on temporal evidence classification online
Our Coling 2014 paper “Prior-informed distant supervision for temporal evidence classification” by Ridho Reinanda and Maarten de Rijke is available online now. Temporal evidence classification, i.e., finding associations between temporal expressions and relations expressed in text, is an important part of temporal relation extraction. To capture the variations found in this setting, we employ a distant supervision…
ECAI 2014 paper on detecting the reputation polarity of microblog posts online
Our ECAI paper “Detecting the reputation polarity of microblog posts” by Cristina Garbacea, Manos Tsagkias and Maarten de Rijke is available online now. We address the task of detecting the reputation polarity of social media updates, that is, deciding whether the content of an update has positive or negative implications for the reputation of a given entity….
ICML 2014 paper on K-armed dueling bandit problem online
Our ICML 2014 paper “Relative upper confidence bound for the K-armed dueling bandit problem” by Masrour Zoghi, Shimon Whiteson, Remi Munos and Maarten de Rijke is available online now. This paper proposes a new method for the K-armed dueling bandit problem, a variation on the regular K-armed bandit problem that offers only relative feedback about pairs of…

SIGIR 2014 paper on hierarchical multi-label classification of social text streams online
Our SIGIR 2014 paper on “Hierarchical multipliable classification of social text streams“ by Zhaochun Ren, Maria-Hendrike Peetz, Shangsong Liang, Willemijn van Dolen and Maarten de Rijke is available online now. Hierarchical multi-label classification assigns a document to multiple hierarchical classes. In this paper we focus on hierarchical multi-label classification of social text streams. Concept drift, complicated relations…
SIGIR 2014 paper on the use of fusion for diversification online
Our SIGIR 2014 paper “Fusion helps diversification” by Shangsong Liang, Zhaochun Ren and Maarten de Rijke is available online now. A popular strategy for search result diversification is to first retrieve a set of documents utilizing a standard retrieval method and then rerank the results. We adopt a different perspective on the problem, based on data…
SIGIR 2014 paper on microblog retrieval online
Our SIGIR 2014 paper “A syntax-aware re-ranker for microblog retrieval” by Aliaksei Severyn, Alessandro Moschitti, Manos Tsagkias, Richard Berendsen and Maarten de Rijke is online now. We tackle the problem of improving microblog retrieval algorithms by proposing a robust structural representation of (query, tweet) pairs. We employ these structures in a principled kernel learning framework that automatically…
