DiCo Corpus: Dictionnaires ComparésVersion française


The DiCo corpus contains a lot of information on some French dictionaries, such as the headwords added to or removed from dictionaries' nomenclature. This information was obtained by manually and exhaustively comparing the successive editions of the same dictionary, for example, the Petit Larousse 2005 with the Petit Larousse 2006, then the latter with the Petit Larousse 2007, etc.

Further details on the comparison method are given in (Martinez, 2009) and (Martinez, 2013), available below.
