System and method for dynamic query substitution

Abstract

A system for dynamic substitution of a user query adapted for use in an online fashion platform is provided. The system includes a query retrieval module configured to retrieve the user query from the online fashion platform. The user query is provided by a user and the user query has one or more query attributes. The system also includes a session data module configured to store session data collected over a plurality of sessions on the online fashion platform. The system further includes an analytics module coupled with the session data module and the query retrieval module and is configured to analyze the user query to identify and extract a query object and one or more query attributes. The analytics module is configured to compute a popularity score for each query attribute. The popularity score is a function of the number of times an article related to the product attribute was searched. The analytics module is further configured to compute an affinity score between each query attribute and related product attributes. The affinity score between two related product attributes is a function of approximate substitution of one product attribute with another. In addition, the analytics module is configured to generate a weighted entity-affinity relationship graph (EARG) based on the popularity scores and the affinity scores. Furthermore, the system includes a query substitution module configured to generate a plurality of substitute queries sorted in order of closeness to the user query using EARG.
