Table 4: Baseline results obtained for various features
['[BOLD] #Training Examples', '[BOLD] Features', '[BOLD] Correlation Coefficient', '[BOLD] RMSE Value']
As we can see, the correlation coefficient is much higher (better) using only the 4 features obtained from the OR and AND operator for all of the experiments. Here, too we see that the RMSE value is lower (better) for the 4 features extracted from the OR and AND operator for all of the experiments. From the results, we see that the features calculated using BM25 and Indri models are much better in representing our data than the methods used in the baseline.
