Abstract. We present a suite of applications used for the Italian Treebank which share their linguistic processor and end up finally in higher level annotation tool called “FILES”. The first application “FILES ” – Fully Integrated Linguistic Environment for Syntactic and Functional Annotation- is a prototype for a fully integrated linguistic environment for syntactic functional annotation of corpora. It takes as input tagged and disambiguated tokenized texts, a file containing the same text split into sentences, and a files containing the morphosyntactic and semantic features associated to each tagged token. Tokens may be aither single words, polywords, abbreviations or punctuation marks. An as yet separated module of “FILES ” is the syntactic constituency annotation environment which uses a shallow parser on the same tagged files and produces a fully bracketed output where each sentence is a record. Files contaning bracketed sentences are given as input to Syntactic Constituency Annotation Tool “SCAT” for manual verification. 1
