AB  - 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.
