IDF Terms

Approximatley 300k plus terms identified from IDF analysis. For interpretation, IDF scores that are low, say a 1 or 4, mean the terms were common, and not good at distinguishing between documents or studies. While a higher IDF means it is a unique term, that can distinguish between docs. To display this information more efficency, I have created some buckets to group IDF scores, and then performed counts of how many IDF terms fall into each bucket. Low is bad distinguisher. High is good distinguisher.

IDF Table of Example Terms

Terms that are that the beginning of the table, found in buckets 0-3, are the worst terms and are not good at distinguishing between documents or studies. The terms at the end of the table, found in buckets 10-11, 11-12, 12+, are the best terms, those that are good for distinguishing between documents or studies. The purpose of this table is to just provide examples.
