Natural language search results for intent queries

摘要

Systems and methods provide natural language search results to clear-intent queries. To provide the natural language search results, a system may parse a document from an authoritative source to generate at least one heading-text pair, the text appearing under the heading in the document. The system may assign a topic and a question category to the heading-text pair and store the heading-text pair in a data store keyed by the topic and the question category. The system determines that a query corresponds to the topic and the question category, and provides the heading-text pair as a natural language search result for the query. In some implementations, the text portion of the heading-text pair may be a paragraph or a list of items and the natural language search result may be provided with conventional snippet-based search results in response to the query.

主权项

1. A computer-implemented method comprising:
parsing, using at least one processor, documents from authoritative sources to generate heading-text pairs, a heading-text pair being taken from document contents; for each heading-text pair:
associating, using the at least one processor, the heading-text pair with an intent template of a plurality of intent templates, the associated intent template having an associated question category,determining a topic and a question category for the heading-text pair based on the associated intent template, andstoring the heading-text pair in a data store keyed by topic and question category;determining that a query corresponds to a first intent template of the plurality of intent templates, the first intent template having a respective question category;determining a first topic for the query based on the first intent template;retrieving a heading-text pair from the data store that has a topic and question category key that corresponds with the first topic and respective question category; andproviding a search result for the query, wherein the search result includes the retrieved heading-text pair.
