Open Information Extraction (Open IE) serves for the analysis of vast amounts of texts by extraction of assertions, or rela- tions, in the form of tuples ?argument 1; relation; argument 2?. Various approaches to Open IE have been designed to per- form in a fast, unsupervised manner. All of them require language specific infor- mation for their implementation. In this work, we introduce an approach to Open IE based on syntactic constraints over POS tag sequences targeted at Spanish lan- guage. We describe the rules specific for Spanish language constructions and their implementation in EXTRHECH, an Open IE system for Spanish. We also discuss language-specific issues of implementa- tion. We compare EXTRHECH?s perfor- mance with that of REVERB, a similar Open IE system for English, on a paral...
