Incorporating Word Embeddings into Open Directory Project based Large-scale Classification
Table 3: Comparison of Category Vector Generations on the ODP Dataset (2,735 categories)
['[EMPTY]', 'Precision', 'Recall', 'F1-score']
We first compare the two methods to generate category vectors with the ODP dataset (2,735 categories). Unexpectedly, we observe that a simple ODPCV(Algebra) clearly outperforms a relatively elaborate ODPCV(Embedding). Thus, we adopt ODPCV(Algebra) in the remaining experiments, which is simply denoted by ODPCV.
