The Need For KB Analysis
uLarge-scale knowledge repositories will necessarily
contain KBs produced by multiple authors in
multiple settings
uKBs for applications will typically be built by
assembling and extending multiple
modular KBs from repositories that may
not be consistent
uKBs developed by multiple authors will frequently
u Express overlapping knowledge in different, possibly contradictory ways
u Use differing assumptions
and styles
uFor such KBs to be used as building blocks -
They must be reviewed for appropriateness and
“correctness”
uThat is, they must be analyzed
