Implicit-Explicit Representations for Case-Based Retrieval

Abstract

CCS CONCEPTS

-

We propose an IR framework to combine the implicit representations — identified using distributional representation techniques — and the explicit representations — derived from external knowledge sources — of documents to improve medical case-based retrieval. Combining implicit-explicit representations of documents aims at enriching the semantic understanding of documents and reducing the semantic gap between documents and queries. • Information systems → Document representation; Query representation; Information extraction; Relation-based information retrieval; Semantic gap
