These difficulties largely stem from the fact that the temporal meaning conveyed by grammatical means interacts with many(More)
Corpora of sentences annotated with grammatical information have been deployed by extending the basic lexical and morphological data with increasingly complex information, such as phrase constituency, syntactic functions, semantic roles, etc. As these corpora grow in size and the linguistic information to be encoded reaches higher levels of sophistication,(More)
We describe the semi-automatic adaptation of a TimeML annotated corpus from English to Portuguese, a language for which TimeML annotated data was not available yet. In order to validate this adaptation, we use the obtained data to replicate some results in the literature that used the original English data. The fact that comparable results are obtained(More)
This paper reports on the participation of the Portuguese grammar LXGram in the Shared Task " Comparing Semantic Representations " of STEP 2008. In view of the goals of this Shared Task, the main characteristics of this grammar are briefly introduced and the semantic formalism that it employs is described. The data for the Shared Task were obtained by(More)
This paper describes the creation of an innovative and highly parallel tree-bank of three languages from different language groups — English, Por-tuguese and Bulgarian. The linguistic analyses for the three languages are done by compatible parallel automatic HPSG grammars using the same formalism , tools and implementation strategy. The final analysis for(More)
