A System For Extraction Of Temporal Expressions From French Texts Based On Syntactic And Semantic Constraints
Proceedings of the ACL 2001 Workshop on Temporal and Spatial Information Processing
We present a system for extraction of temporal expressions from French texts. The identification of the temporal expressions is based on a context-scanning strategy (CSS) which is carried out by two complementary techniques: search for regular expressios and left-to-right and right-to-left local chartparsing. A number of semantic and distant-dependency constraints have been integrated to the chartparsing procedure in order to improve the precision of the system.
