Abstract

In this paper we describe our participation to the CLEF 2018 Consumer Health Search Task, sub task IRTask1. This track aims to evaluate and advance search technologies aimed at supporting consumers to find health advice online. Our solution addressed this challenge by extending the Entity Query Feature Expansion model (EQFE), a knowledge base (KB) query expansion method. In previous work we showed that Wikipedia, UMLS and CHV can be effective as basis for CHS query expansions within the EQFE model. To obtain the query expansion terms, first, we mapped entity mentions to KB entities by performing exact matching. After mapping, we used the Title of the mapped KB entities as the source for expansion terms. For our first three expanded query sets, we expanded the original queries sourcing expansion terms from each of Wikipedia, the UMLS, and the CHV. For our fourth expanded query set, we combined expansion terms from Wikipedia and CHV.
