Table 1
Some popular examples of statistics-based term weighting schemes.
| | TWS | Term frequency factor | Collection frequency factor |
| | TF | Term frequency (TF) | NONE | | DF | NONE | Document frequency (DF) | | TF-IDF | Term frequency (TF) | Inverse document frequency (IDF) | | TF-CHI2 | Term frequency (TF) | Globalized chi-square score (CHI2) | | LogTF-RF | Logarithm of term frequency | Relevance frequency (RF) | | TF-IGM | Term frequency (TF) | Inverse gravity moment (IGM) | | SQRT_TF-IGM | Square root of term frequency | Inverse gravity moment (IGM) | | TF-IEF | Term frequency (TF) | Inverse exponential frequency (IEF) |
