York University at TREC 2009: Chemical Track.
(05/01/2014)
Our chemical experiments mainly focus on addressing three major problems in two chemical information retrieval tasks, Technology Survey (TS) task and Prior Art (PA) task. The three problems are: (1) how to deal with chemical terminology synonyms; (2) how to deal with chemical terminology abbreviation; (3) how to deal with long queries in Prior Art (PA) task. In particular, we propose a query expansion algorithm for TS task and a keyword-selection algorithm for PA task. The Mean Average Precision (MAP) for our TS task run 'york09ca07' using Algorithm 1 was 0.2519 and for our PA task run 'york09caPA01' using Algorithm...

The Mean Average Precision (MAP) for our TS task run 'york09ca07' using Algorithm 1 was 0.2519 and for our PA task run 'york09caPA01' using Algorithm 2 was 0.0566. The evaluation results show that both algorithms are effective for improving retrieval performance.
