Incorporating Word Embeddings into Open Directory Project based Large-scale Classification
(b) moderate-scale (13 categories)
['[EMPTY]', 'Precision', 'Recall', 'F1-score']
We observe that ODPCV+WV outperforms all the other proposed methods, as well as the baselines. ODPCV+WV performs better than ODP over 9%, 12%, and 10% on average in terms of precision, recall, and F1-score, respectively. This can be explained by the fact the distribution of webpages is skewed toward a few categories in the original ODP Actually, we observe that 73% of ODP categories contain fewer than five webpages. We also compare the performance of CNN with the ODP baseline on the ODP test dataset with 13 target categories.
