Abstract
There has been recent research in open-ended information
extraction from text that finds relational triples of the form
(arg1, relation phrase, arg2), where the relation phrase is a
text string that expresses a relation between two arbitrary
noun phrases. While such a relational triple is a good first
step, much further work is required to turn such a textual rela-
tion into a logical form that supports inferencing. The strings
from arg1 and arg2 must be normalized, disambiguated, and
mapped to a formal taxonomy. The relation phrase must like-
wise be normalized and mapped to a clearly defined logi-
cal relation. Some relation phrases can be mapped to a set
of pre-defined relations such as Part-0f and Causes. We fo-
cus instead on arbitrary relation phrases that are discovered
