Query: A Hybrid Citation Retrieval Algorithm for Evidence-based Clinical
  Knowledge Summarization: Combining Concept Extraction, Vector Similarity and
  Query Expansion for High Precision   Novel information retrieval methods to identify citations relevant to a
clinical topic can overcome the knowledge gap existing between the primary
literature (MEDLINE) and online clinical knowledge resources such as UpToDate.
Searching the MEDLINE database directly or with query expansion methods returns
a large number of citations that are not relevant to the query. The current
study presents a citation retrieval system that retrieves citations for
evidence-based clinical knowledge summarization. This approach combines query
expansion, concept-based screening algorithm, and concept-based vector
similarity. We also propose an information extraction framework for automated
concept (Population, Intervention, Comparison, and Disease) extraction. We
evaluated our proposed system on all topics (as queries) available from
UpToDate for two diseases, heart failure (HF) and atrial fibrillation (AFib).
The system achieved an overall F-score of 41.2% on HF topics and 42.4% on AFib
topics on a gold standard of citations available in UpToDate. This is
significantly high when compared to a query-expansion based baseline (F-score
of 1.3% on HF and 2.2% on AFib) and a system that uses query expansion with
disease hyponyms and journal names, concept-based screening, and term-based
vector similarity system (F-score of 37.5% on HF and 39.5% on AFib). Evaluating
the system with top K relevant citations, where K is the number of citations in
the gold standard achieved a much higher overall F-score of 69.9% on HF topics
and 75.1% on AFib topics. In addition, the system retrieved up to 18 new
relevant citations per topic when tested on ten HF and six AFib clinical
topics.
