TREEBANK_3/docs/prsguid1.pdf

Homework Task – Systematically tregex search patterns for selected constructions from the Bracketing Guidelines, e.g. Gapping – Report on how many constructions are found in the Wall Street Journal text – Present your results next time in class

Example: looking for passives Pattern: using variable names and regex group numbering for coindexation matching for passives (NP-SBJ-i and object of VP [NP [ –NONE- [ -*-I ]]])
