</br>
<h3>Introduction</h3>
</br></br>
<p>DEFT Spanish Light and Rich ERE Annotation, Linguistic Data Consortium (LDC) 
Catalog Number LDC2025T04, was developed by LDC and 
consists of 158 Spanish discussion forum and newswire documents annotated for entities, 
relations and events (ERE).</p>
  </br>
<p>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.</p>
</br>
<p>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.</p>
