NovaSearch at TREC 2013 Microblog Track: Experiments with reranking using Wikipedia.
Flávio Martins, André Mourão, João Magalhães · Text REtrieval Conference · 2013
Users engaged in microblogging services and social-media apps contribute to multiple real-time text streams which amass large volumes of messages often sparked by events reported in newswire and in other media. We explore the use of external sources to detect topic popularity surges and improve microblog search performance using timebased language models [3]. The major novelty concerns the analysis that explores Wikipedia page view streams to find topic interest spikes. We obtained promising initial results when using evidence from Wikipedia for temporal reranking with the Tweets2013 dataset.
