How to Evaluate NLP Tools for Entity Extraction

You have some documents, and you want to extract information, but how do you decide which NLP tool or library to use? Comparing NLP tools is not a straightforward exercise. Each tool may extract a different set of entity types, classify the same entity a little differently, or provide output in different formats, thus preventing direct comparison.

Basis Technology often performs evaluations of disparate NLP tools. We want to show you how we overcome these challenges to produce meaningful scores that enable us to compare tools.
This webinar will also introduce best practices for annotating a test data set and selecting a gold standard, as well as common ways to measure both the accuracy of the annotation and the extraction.
