IDEL: In-Database Entity Linking with Neural Embeddings
Table 3. Runtime (in seconds) of different stages in IDEL for the entity type Building.
['Phase', 'Step', 'RT (sec)']
We observe for steps at data loading time, such as embed sentences and relational tuples, an average of 208 seconds. For the query execution time and creating candidate tuples, storing embeddings, applying the similarity metric, ranking and pruning TopK entity mappings, we observe an average of 116 seconds. Our conclusion is that once a user has set up in IDEL an initial query mapping from entity types in relational data to sentences in text data, the system can asynchronous rebuild embeddings in the background to achieve very high Precision@1 values even for unseen entities for the next time the user hits the same query.
