The research reported in this paper is part of the activities carried out within the CLARIN - Common Language Resources and Technology Infrastructure - project. CLARIN is a large-scale pan-European project to coordinate and make language resources and technology available and readily useable. CLARIN is devoted to the creation of a persistent and stable infrastructure serving the needs of the European Humanities and Social Sciences (HSS) research community. HSS researchers will be able to efficiently access distributed language resources and apply analysis and exploitation tools relevant for their research questions. In this paper we present a real case of language technology usage, addressed as a CLARIN scenario: the building of a support work flow for lexicographers who are creating a
dictionary of Spanish as a second language by automatically clustering the corpus concordances with which they work.
