Detailed Description

Database class to read and count parse tree events.

Constructor & Destructor Documentation

semantics::Event_db::Event_db ( )

inline

default ctor, creates empty database

semantics::Event_db::Event_db ( std::string  event_file, std::string  lexicon_file, bool  learn = true, int  num_lines = 10000  )

inline

constructs an event database object

Parameters

event_file	(path-to-)filename as string
learn	if true, counts events and builds a probability model

Member Function Documentation
