  • [Title] Evaluating relevance ranking strategies for MEDLINE retrieval.
  • This paper evaluates the retrieval effectiveness of relevance ranking strategies on a collection of 55 queries and about 160,000 MEDLINE((R)) citations used in the 2006 and 2007 Text Retrieval Conference (TREC) Genomics Tracks.
  • The authors study two relevance ranking strategies: term frequency-inverse document frequency (TF-IDF) weighting and sentence-level co-occurrence, and examine their ability to rank retrieved MEDLINE documents given user queries.
  • Furthermore, the authors use the reverse chronological order-PubMed's default display option-as a baseline for comparison.
  • Retrieval effectiveness is assessed using both mean average precision and mean rank precision.
  • Experimental results show that retrievals based on the two strategies had improved performance over the baseline performance, and that TF-IDF weighting is more effective in retrieving relevant documents based on the comparison between the two strategies.
