Leveraging Schema Labels to Enhance Dataset Search
Table 3: Supervised ranking results on table retrieval.
['Method', 'NDCG@5', '@10', '@15', '@20']
We first generate schema labels for the table corpus shared by Zhang and Balog [ Each feature is one type of semantic similarity between query and schema labels. Four features are calculated using the measurement proposed by Zhang and Balog (one early fusion feature, three late fusion features) and the last feature is the negative of Word Mover’s Distance.
