The LABLITA Corpus & the Language into Act Theory: Analysis of Viterbo Excerpts

The LABLITA Corpus is aligned at the utterance level, characterized by high diaphasic variation, and organized with respect to a fine-grained metadata grid (CHAT and IMDI standards). The Language into Act Theory (L-AcT) provides a theoretical framework for the LABLITA collection, assuming a pragmatic basis for Information Structure and a strict correspondence between prosodic and information units. L-AcT provides criteria for Information Structure tagging in the heavily annotated, informal sub-part of the corpus for cross-linguistic comparison (available in the DB-IPIC database). The paper demonstrates how the Viterbo excerpts can be annotated in accordance with L-AcT and how the LABLITA Corpus has been exploited for comparative studies.
