Gargett, Andrew; Firth, Rob and Aletras, Nikolaos (2020). LegalOps: A Summarization Corpus of Legal Opinions. In: 2020 IEEE International Conference on Big Data (Big Data), IEEE, pp. 2117–2120.



We present a new, large-scale corpus for training and evaluating text summarization systems on legal opinions, called LegalOps. The corpus includes ~ 14K opinions together with their summaries from U.S. Federal Courts, e.g. the Supreme Court and Federal Appeals Courts. The aim of this paper is to provide a novel data source of sufficient variety that it will advance theoretical work on modeling the particular patterns within legal discourse, but also of sufficient size that it will provide a new challenging testbed for state-of-the-art automatic summarization models.
