Cross Market Modeling for Query-Entity Matching

Abstract: Given a query, the query-entity (QE) matching task involves iden- tifying the best matching entity for the query. When modeling this task as a binary classification problem, two issues arise: (1) features in specific global markets (like de-at: German users in Austria) are quite sparse compared to other markets like en-us, and (2) train- ing data is expensive to obtain in multiple markets and hence lim- ited. Can we leverage some form of cross market data/features for effective query-entity matching in sparse markets? Our solution consists of three main modules: (1) Cross Market Training Data Leverage (CMTDL) (2) Cross Market Feature Leverage (CMFL), and (3) Cross Market Output Data Leverage (CMODL). Each of these parts perform “signal” sharing at different points during the classification process. Using a combination of these strategies, we show significant improvements in query-impression weighted coverage for the query-entity matching task.
