Abstract
An approach is provided for semantic filtering to filter an input data stream of a data system to reduce an amount of data processed by the data system. The approach, for example, involves retrieving training data comprising a plurality of training data items responsive to a plurality of training queries conducted in a data system. The approach also involves performing a vectorization and a tokenization of the training data to generate a plurality of vectors comprising a plurality of tokens extracted from the plurality of training data items. The approach also involves computing a plurality of reference semantic scores for the plurality of vectors based on a semantic distance between the plurality of tokens. The approach also involves transforming the plurality of reference semantic scores into a plurality of transformed reference semantic scores based on a modulation function. The approach also involves fitting a filtering function to the plurality of transformed reference semantic scores. The approach also involves providing the filtering function to filter an input data stream of the data system to reduce an amount of data processed by the data system.
