Abstract:

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 2 was 0.0566. The evaluation results show that both algorithms are effective for improving retrieval performance.
