Abstract: Personalized named entity recognition may be accomplished by parsing input text to determine a subset of the input text, generating a plurality of queries based at least in part on the subset of the input text, submitting the queries to a plurality of reference resources, processing responses to the queries and generating a vector based on the responses, and performing classification based at least in part on the vector and a set of model parameters to determine a likelihood as to which named entity category the input text belongs.
