Extensions to the GrETEL Treebank Query Application

In this paper we describe the extensions we made to an existing treebank query application (GrETEL). These extensions address user needs expressed by multiple linguistic researchers and include (1) facilities for uploading one’s own data and metadata in GrETEL; (2) conversion and cleaning modules for uploading data in the CHAT format; (3) new facilities for analysing the results of the treebank queries in terms of data, metadata and combinations of them. These extensions have been made available in a new version (Version 4) of GrETEL
