The results of the term association approach are presented: (1) all the runs are under the same settings as the baselines in Table 1, including the parameter settings of (k1, b), the indices and the evaluation measures; (2) the factor analysis base algorithms and the recursive re-ranking algorithms are applied; (3) the values in the parentheses are the relative rates of improvement over the original results. |
