Introduction
DEFT Spanish Light and Rich ERE Annotation was developed by the Linguistic Data Consortium (LDC) and consists of 158 Spanish discussion forum and newswire documents annotated for entities, relations and events (ERE).
DARPA's Deep Exploration and Filtering of Text (DEFT) program aimed to address remaining capability gaps in state-of-the-art natural language processing technologies related to inference, causal relationships and anomaly detection. LDC supported the DEFT program by collecting, creating and annotating a variety of data sources.
Light ERE annotation labels entity mentions for the target set of entity, relation and event types between and among those entities including coreference. Rich ERE annotation expands types and tagging in the entities, relations, and events annotation tasks and replaces strict event coreference with a more loosely defined event hopper annotation. Further information about the annotation methodology is contained in the documentation accompanying this release.
Data
The source data consists of Spanish newswire text and Latin American discussion forum data from DEFT Spanish Treebank LDC2018T01. 128 documents were annotated following Light ERE annotation guidelines. 154 files were labeled with Rich ERE annotation, 124 of which were also labeled with Light ERE annotation.
Below is a data summary:
| ERE | Files | Words | Entities (mentions) | Fillers | Relations | Event Mentions | Event Hoppers |
| Light | 128 | 72,896 | 4,309(11,003) | N/A | 2,382 | 1,193 | 725 |
| Rich | 154 | 104,833 | 5,895(15,537) | 1,913 | 3,005 | 4,423 | 3,093 |
Source documents are in plain text format, annotation is in XML format, and both are UTF-8 encoded.
