Heuristics and Parse Ranking
B. Srinivas, Christine Doran, Seth Kulick
There are currently two philosophies for building grammars and parsers -- Statistically induced grammars and Wide-coverage grammars. One way to combine the strengths of both approa…
Some Novel Applications of Explanation-Based Learning to Parsing Lexicalized Tree-Adjoining Grammars
B. Srinivas, Aravind Joshi
In this paper we present some novel applications of Explanation-Based Learning (EBL) technique to parsing Lexicalized Tree-Adjoining grammars. The novel aspects are (a) immediate g…
Bootstrapping A Wide-Coverage CCG from FB-LTAG
Christine Doran, B. Srinivas
A number of researchers have noted the similarities between LTAGs and CCGs. Observing this resemblance, we felt that we could make use of the wide-coverage grammar developed in the…
Status of the XTAG System
Christy Doran, Dania Egedi, Beth Ann Hockey +1
XTAG is an ongoing project to develop a wide-coverage grammar for English, based on the Feature-based Lexicalized Tree Adjoining Grammar (FB-LTAG) formalism. The XTAG system integr…
Feature-Based TAG in place of multi-component adjunction: Computational Implications
B. A. Hockey, B. Srinivas
Using feature-based Tree Adjoining Grammar (TAG), this paper presents linguistically motivated analyses of constructions claimed to require multi-component adjunction. These featur…
Disambiguation of Super Parts of Speech (or Supertags): Almost Parsing
Aravind K. Joshi, B. Srinivas
In a lexicalized grammar formalism such as Lexicalized Tree-Adjoining Grammar (LTAG), each lexical item is associated with at least one elementary structure (supertag) that localiz…
