MACHINE LEARNING TECHNIQUES TO PREDICT DOCUMENT TYPE FOR INCOMPLETE QUERIES

Abstract:

Techniques for using machine learning to predict document types for incomplete queries are provided. In one technique, one or more characters from input are identified. For each character, an embedding that corresponds to that character is retrieved. The embedding was machine-learned while training a neural network that outputs multiple classifications, each corresponding to a different document type. One or more embeddings, each corresponding to one of the characters, are input into the neural network. Based on the inputting, the neural network generates an output that comprises multiple values that includes (1) a first value that reflects a first probability that the input is associated with a first document type and (2) a second value that reflects a second probability that the input is associated with a second document type. Based on the first and second probabilities, a set of query completions is identified and presented on the computing device.
