PROCESSING OF FRESH-SEEKING SEARCH QUERIES

摘要

In one implementation, a device may identify documents that are associated with a timestamp. The device may sort the documents, based on the timestamps, create a timeline of documents; and may determine a best-fit step function to fit the timeline of documents. The device may identify at least one event, associated with the timeline of documents, based on the best-fit step function. The device may modify relevance scores associated with the documents based on the identified at least one event.

1. A method performed by one or more server devices, the method comprising:
receiving, by at least one of the one or more server devices and from a client, a search query; identifying, by at least one of the one or more server devices, a plurality of documents relevant to the search query,
where each of the plurality of documents is associated with a timestamp and a relevance score; sorting, by at least one of the one or more server devices, the plurality of documents, based on the timestamps, to create a timeline of documents; determining, by at least one of the one or more server devices, a best-fit step function to fit the timeline of documents,
the best-fit step function being determined by averaging a plurality of values associated with the timeline of documents, andthe best-fit step function including a plurality of values,
each value, of the plurality of values included in the best-fit step function, corresponding to a respective date associated with an increase in a quantity of documents, of the plurality of documents, that are relevant to the search query; identifying, by at least one of the one or more server devices, at least one event, associated with the timeline of documents, based on the best-fit step function; determining, by at least one of the one or more server devices and based on the at least one event, a type of query associated with the search query,
determining the type of query including:
comparing information associated with a particular value, of the plurality of values included in the best-fit step function, to information associated with at least one other value of the plurality of values included in the best-fit step function; anddetermining, when the comparison of the information associated with the particular value and the information associated with the at least one other value satisfies a threshold, the type of query; modifying, by at least one of the one or more server devices and based on the determined type of query and the at least one event, the relevance scores of the plurality of documents; and transmitting, by at least one of the one or more server devices, information associated with a portion of the plurality of documents, based on the modified relevance scores, to the client.
