York University at TREC 2010: Chemical Track

چکیده
We participated two chemical information retrieval tasks, Technology Survey (TS) task and Prior Art (PA) task in TREC 2010 chemical track. We aim to discover extra relevant chemical compounds for a given query. We investigate various basic retrieval models as well as corresponding Pseudo Relevance Feedback(PRF) models in chemical experiments. In order to eliminate low quality feedback documents, QRocDFR, an early work of York University, is introduced to consider the quality of each feedback chemical document. Further analysis could be made when we were able to reach the evaluation results.

York University at TREC 2006: Legal Track
York University participated in the legal track this year. For this track, we developed an Okapi-based Legal Search Engine (LSE) v1.0. Our experiments mainly focused on evaluating the effect of a probabilistic text retrieval model on the legal domain. In order to address the special problems in legal text retrieval, new automatic feedback methods and term weighting methods are proposed and tested.

York University participated in the TREC 2008 Blog track, by introducing two opinion finding features. By initially focusing solely on the sentiment terms found in a document, using two different methods, and not considering the topic relevance, we saw an overall negative impact in the final evaluations. Post-TREC improvements show the necessity of combining opinion weights with the topic relev...

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 ex...

York University participated in the terabyte track this year. Using the GOV2 collection, we used filtering techniques to shorten the amount of data to be indexed before indexing into eight partitions. As there were several different subsections of the terabyte track, we chose to participate in the ad hoc and named page retrieval runs. Our technique involved partitioned indexes across a single m...
