示例1: load_parser_model
# 需要导入模块: import CharniakParser [as 别名]
# 或者: from CharniakParser import loadHeadInfoOnly [as 别名]
def load_parser_model(self, model_dir, terms_only=False,
heads_only=False, **parser_options):
"""Load the parsing model from model_dir and set parsing
options. In general, the default options should suffice but see
the set_parser_options() method for details. Note that the parser
does not allow loading multiple models within the same process
(calling this function twice will raise a RuntimeError).
If terms_only is True, we will not load the full parsing model,
just part of speech tag information (intended for tools which
only call things like Tree.evaluate()). If heads_only is True,
we will only load head finding information (for things like
Tree.dependencies(). If both are set to True, both of these will
be loaded but the full parsing model will not."""
