- Description
- This paper focuses on the use of two algorithms for the integration of two broad-coverage dependency-based parsing systems into ExtrAns, an answer extraction system that operates over Unix manual pages. In the process, ExtrAns uses a semantic interpreter that converts the output of the parser into flat logical forms. The semantic interpreter for the first parsing system, Link Grammar, uses a topdown algorithm, whereas the semantic interpreter for the second parsing system, Conexor FDG, uses a bottom-up algorithm. After showing the differences between the structures returned by both parsing systems, the paper compares the algorithms for semantic interpretation and comments on their adequacy for the production of flat logical forms.
