The TAGFACT annotator and editor: A versatile tool

Keywords: annotation tool, corpus creation, corpus edition, Spanish journalistic texts


The multifunctional tool this paper presents has been developed within the TAGFACT project, a project that aims to automate the annotation of factuality –understood as the degree of commitment with which the writer presents situations– in Spanish journalistic texts. In what follows, the tool, which allows the compilation of the texts and the manual annotation of predicates, is described. The corpus created using it has been extracted in groups of three pieces of news covering the same event from newspapers with different ideologies (left wing, right wing and centrist). It is made up of 176 different pieces of news, containing 1,359 sentences and 46,947 words. The tool has been used so far to manually annotate a section of the ‘Gold Standard’ (approximately 10,000 words). It has proved to be versatile in that it allows for both the creation and management of corpora and corpus annotation, using any tags the user wants depending on the purpose of each corpus.
