Up: Document term weighting
Previous: Term weighting in
- For example a database consists of 10 documents.
A term which occurs 10 times in a document has the idf = 1/10.
The same term which occurs in 10 documents has also idf = 1/10.
One can say in both cases the term has the same relevance. This may
not be correct.
- The normalization factor is not the weight of each term in the document but
number of terms in a document.
