The Corpus Gold Standard TAGFACT v.0.1 is a Spanish corpus manually annotated with factuality information. The corpus consists of 11 news items (basically political), with a total of 5,240 words (approximately 160 sentences) extracted from newspapers. They are all newspapers published in Spain and, predictably, are mostly in peninsular Spanish. The corpus has been manually annotated with information about factuality of 633 predicates. Six linguists worked on it, all of whom had undergone training. The analysis of inter-annotator agreement was made in pairs, a total of 30, and, on average, the result was acceptable. Two XML versions of the Corpus Gold Standard TAGFACT v.0.1 are available. In each one different tagsets (defined with more or less abstraction) have been used, but equivalences have been stablished.
