Introduction

DEFT Spanish Treebank was developed by the Linguistic Data Consortium (LDC) and the Language and Computation Center (CLiC), University of Barcelona. It contains treebank annotation of international Spanish newswire text and Latin American Spanish discussion forum data created for the DARPA Deep Exploration and Filtering of Text (DEFT) program.

DEFT aimed to improve state-of-the-art capabilities in automated deep natural language processing with a particular focus on technologies dealing with inference, casual relationships and anomaly detection across several languages. DEFT Spanish Treebank supported the program's goal of deep natural language understanding.

Data

Newswire source files were selected from Spanish Gigaword Third Edition (LDC2011T12) and were manually sentence-segmented for DEFT. Discussion forum source files were selected from Spanish discussion forum source data collected by LDC, consisting of continuous multi-posts of 100-1000 words.

This release contains 114 files (54,394 tokens) of newswire data and 60 files (55,307 tokens) of discussion forum data all of which were annotated with constituents and syntactic functions. The annotation guidelines for DEFT Spanish Treebank are included in the documentation accompanying this release.

Source documents are presented as plain text files with one sentence unit per line. Treebank annotation files are in xml.
