1. A non-transitory computer-readable storage medium comprising computer-readable instructions that, in response to execution, cause a computing system to perform operations, comprising: receiving information indicative of initial entities for content and initial scores associated with the initial entities from one or more content annotation sources; aggregating the information indicative of initial entities for content and initial scores associated with the initial entities received from the one or more content annotation sources; defining a range of values; mapping the initial scores to respective values within the defined range, the mapping producing calibrated scores within the defined range; selecting weights based on joint performance conditions; applying the selected weights to the calibrated scores within the defined range to produce weighted, calibrated scores; selecting a linear aggregation model from among a plurality of linear aggregation models; combining the weighted, calibrated scores based on the selected linear aggregation model to generate a final score; and determining whether to annotate the content with at least one of the initial entities based on a comparison of the final score and a defined threshold value.

The non-transitory computer-readable storage medium of claim 1 , wherein the joint performance conditions comprise at least two of coverage associated with one or more of the initial entities, completeness associated with one or more of the initial entities or quality associated with one or more of the initial entities.
