tgrep

Version 2 (UCSD Linux port)

tgrep is a tree-oriented search program, similar in functionality to the UNIX grep utility, but with additional operators that permit searches based on dominance and precedence relations. It is specifically designed to search for grammatical structures in corpora that have been parsed following the Penn LDC Treebank Style. The current version is based on the LDC distributed sources and has been ported to Linux. This software is also distributed at the LDC site (see below).
