IDF [Obj,Obj]

Description

Computes IDF of T in DT object pairs

Input

DT [OBJ,OBJ]: a list of object-object pairs.

Output

DTidf [OBJ,OBJ]: IDF-weighted pairs
Tidf [OBJ]: IDF-weighted objects

Parameters

IDF: the IDF weighting scheme variant. P(t|d) = t_nd / d_N, n_D = number of documents, t_nd = number of documents with term t.
- BASIC: non-logarithmic IDF (1 - P(t|d) = 1 - (t_nd / d_N))
- IDFB: non-smoothed IDF (-log( P(t|d) = log ( d_N / t_nd ))
- IDFP: smoothed IDF (log( (d_N - t_nd + 0.5) / (t_nd + 0.5) ))
- IDFPA: alpha-smoothed IDF (alpha * IDFP) Output scores can be aggregated and/or normalized.
