Abstract:
This paper describes a robust finite-state parser implemented for French. The parser attaches
morpho-syntactic tags to cach word and determines clause boundaties. It is a reductionist parser based on
finite state networks and their intersection. We describe essential elements of the rule writing system, and
show how it is actually applied to solve various phenomena, such as argument uniqueness, agreement or
apposition. We show some results which indicate that the parser can parse technical manuals with high
accuracy (in a test sample 95% of part-of speech and fuctional tags were correct). The average number of
parses per sentence is very low , more than 92% of sentences produce less than 4 parses, including the
correct one. A test on very long sentences from newspaper corpora and a discussion of errors provide more
insight into the parser.
