DCU@INEX-2012: exploring sentence retrieval for tweet contextualization (2012)

Abstract For the participation of Dublin City University (DCU) in the INEX-2012 tweet contextualization task, we investigated sentence retrieval methodologies. The task requires providing the context to an ad-hoc real-life tweet. This context is to be constructed from Wikipedia articles. Our approach involves indexing the passages in Wikipedia articles as separate retrievable units, extracting sentences from the top ranked passages, computing the sentence selection score for each such sentence with respect to the query, and then returning the top most similar ones. The simple sentence selection strategy performed quite well in the task. Our best run has ranked rst from the readability perspective and ranked eighth as ordered by informativeness out of 33 ocial runs.
