Words are not Equal: Graded Weighting Model for building Composite Document Vectors
Table 9: Accuracies for Product Review and Movie Review Datasets.
['[BOLD] Features', '[BOLD] Accuracy(1)', '[BOLD] Accuracy(2)']
We see that there is a slight improvement in accuracy on both datasets once we remove stop-words but the major breakthrough occurs once we used weighted averaging technique for construction of document vectors from word vectors.
