GENERATING A QUERY STATEMENT BASED ON UNSTRUCTURED INPUT

摘要

Techniques for generating a query statement to query a dataset may be provided. For example, the query statement can be generated from natural language input, such as a natural language utterance. To do so, the input can be analyzed to detect a sentence, identify words in the sentence, and tag the words with the corresponding word types (e.g., nouns, verbs, adjectives, etc.). Expressions using the tags can be generated. Data about the expressions can be inputted to a classifier. Based on a detected pattern associated with the expressions, the classifier can predict a structure of the query statement, such as what expressions correspond to what clauses of the query statement. Based on this prediction, words associated with the expressions can be added to the clauses to generate the query statement and accordingly query the dataset.

1. A computer-implemented method comprising:
identifying words from a natural language request to search a dataset; associating each of the words with an identifier that identifies a part of speech type of the corresponding word; generating groupings of identifiers, each of the groupings comprising one or more of the identifiers; providing the words and the groupings to a machine learning classifier to generate a structured query to the dataset, the machine learning classifier configured to select a structure of the structured query based on the groupings and to use the words and the structure to generate the structured query; and querying the dataset based on the structured query provided from the machine learning classifier.
