REQUEST PROPOSAL BASED ON SEARCH DATA Russian patent published in 2017 - IPC G06F17/30 

FIELD: information technology.

SUBSTANCE: method of determination of subject-matter prompts based on search data includes the steps of: determination of inquiry qualification; generation of refinement clusters, each of which corresponds to a particular topic included in requests in this refinement cluster and not included in the first request; estimation of each cluster using a number of unique n-grams associated with the specific topic of this refinement cluster; grading refinement clusters based on estimates; selection of a refinement cluster that is the highest grade relative to the others, as the first refinement cluster of search for the first request; and generation of the first topic prompt data, based on the subject associated with the first refinement cluster of search and describing the query containing the request for the first user input of the n-gram, which is the subtopic of the mentioned topic.

EFFECT: reduction of user input data and probability of the topic drift, provision of proposals that are more likely to meet the information needs of users, faster forwarding of users to search results.
