Building an Arabic linguistic resource from a treebank: the property grammartreebank

International audienceThis paper presents a survey of Arabic treebanks to facilitate their reuse for the building of new linguistic resources. In our case, we created from a treebank an automatically induced Property Grammar (GP). So, we discussed characteristics of these treebanks to choose the appropriate one. To build our resource, we adopted an automatic technique, acquiring first a contextfree grammar (CFG) from the chosen treebank, and second, inducing a GP by generating relations between grammatical units described in the CFG
