Analysis of Named Entity Recognitionand Linking for Tweets
Table 9: Tweet-level entity linking performance our entity-disambiguated dataset. YODIE results are for a whole-pipeline approach.
['[BOLD] Name', '[BOLD] Precision', '[BOLD] Recall', '[BOLD] F1']
Note that the recall here is not reliable, as we have “downsampled” the set of URIs returned so that all fall within DBpedia, and DBpedia does not contain references to every entity mentioned within the dataset. In addition, due to the specifics of the CrowdFlower NEL interface, annotators could not indicate missed entities for which no candidates have been assigned, even if such exist in DBpedia. Therefore, no result is placed in bold in this dataset. We perform this downsampling so that we may find the simplest possible base for comparison.
