A major problem in this task is the high degree of lexical variation in documents which makes it very difficult to detect stories that talk about the same event but expressed using different words. We suggest using paraphrases to alleviate this problem, making this the first work to use paraphrases for FSD. We show a novel way of integrating paraphrases with locality sensitive hashing (LSH) in order to obtain an efficient FSD system that can scale to very large datasets. Our system achieves state-of-the-art results on the first story detection task, beating both the best supervised and unsupervised systems. To test our approach on large data, we construct a corpus of events for Twitter, consisting of 50 million documents, and show that paraphrasing is also beneficial in this domain. 1 URL: http://citeseerx.ist.psu.edu/viewdoc/summary?doi=10.1.1.381.4393 http://homepages.inf.ed.ac.uk/miles/papers/naacl12.pdf BASE Hide details 2 Opinion retrieval in twitter Zhunchen Luo; Miles Osborne; Ting Wang In: http://homepages.inf.ed.ac.uk/miles/papers/icwsm12.pdf (2012) BASE Show details 3 Using paraphrases for improving first story detection in news and twitter Miles Osborne; Victor Lavrenko In: http://www.aclweb.org/anthology-new/N/N12/N12-1034.pdf (2012) BASE Show details 4 Constructing parallel corpora for six indian languages via crowdsourcing Matt Post; Chris Callison-burch; Miles Osborne In: http://www.aclweb.org/anthology/W12-3152/ (2012) BASE Show details
