TF-IDF Corpus Creation Service
TF-IDF Corpus Creation Service
This service calculates the TF-IDF (term frequency-inverse document frequency) statistics for concepts and free terms in a selected corpus. When you use it in the Extraction Service, the following calculations will be done:
Concepts and terms are weighted by the TF-IDF values and the score of document specific terms/concepts are boosted.
The scores of common terms/concepts (in the given domain/corpus) are decreased.
For each project TF-IDF statistics can be calculated based on one corpus.
