Gene clustering: 2001: 2
Finding Rules: Algorithm
§For each instance NOT in cluster:
•find set of words in cluster but not in instance
§Collect singleton sets (and remove supersets)
•= “necessary” words
§Collect all other words in sets
•= “sufficient” words
§Collect words in cluster but not in any set
•= “supplementary” words
§Convert sets from CNF to DNF
