(2010): “Lexical analysis of pre and post revolution discourse in Portugal”, in Proceedings of the Third Workshop on Building Comparable Corpora, 7th International Conference on Language Resources and Evaluation (LREC 2010), Malta, pp. 65-712-9517408-6-7http://hdl.handle.net/10451/37431This paper presents a lexical comparison of pre (1954-74) and post (1974-94) revolution parliamentary discourse in four comparable sub-corpora extracted from the Reference Corpus of Contemporary Portuguese (CRPC). After introducing the CRPC, including annotation and meta-data, we focus on a subset of the corpus dealing with parliamentary discourses, more particularly a time frame of forty years divided into four comparable sub-corpora, each covering a ten-year period, two pre revolution and two post revolution. We extract lexical density information as well as salient terms pertaining to each period to make a comparative evaluation of the periods. Our results show how a linguistic analysis essentially based on the use of simple n-gram statistics can produce key insights into the use, change and evolution of the Portuguese language around a critical time period in its history.engconference object
