This volume contains 17 articles, developed from papers that were chosen from among the 44 presentations of work on NooJ presented at the 2013 International NooJ Conference in Saarbrucken in June, 2013. NooJ is a linguistic development environment that allows linguists to formalize a wide gamut of linguistic phenomena, and then test, adapt, share and accumulate each elementary description to build linguistic "modules", that is, structured libraries of linguistic resources. NooJ is also used as a corpus processor that can launch sophisticated queries over large corpora of texts, in order to produce various results, including concordances, statistical analyses, information extraction, and automatic translation. NooJ is used in many research centers; it has recently been endorsed by the European Metashare CESAR Project, and is now available as an open source software at the METASHARE repository. NooJ is also used by a growing number of software companies to construct various Natural Language Processing applications.
