Reducing Workload of Systematic Review Searching and Screening Processes

Harrisen Scells
2017 BCS-IRSG Symposium on Future Directions in Information Access  
This research explores automatic methodologies to reduce the workload relating to the searching and screening processes.  ...  Systematic reviews, in particular medical systematic reviews, are time consuming and costly to produce.  ...  The keywords in the boolean query of the search strategies are annotated with relevant PICO elements manually. Studies are also annotated automatically to extract the PICO elements.  ...

Leveraging coreference to identify arms in medical abstracts: An experimental study

Elisa Ferracane, Iain Marshall, Byron C. Wallace, Katrin Erk
2016 Proceedings of the Seventh International Workshop on Health Text Mining and Information Analysis  
We examine how coreference resolution can aid in identifying the arms of a study, an often overlooked piece of information needed to synthesize the results in a systematic review.  ...  A classification model 1 that performs better with the coreference features supports the intuition that coreference is able to capture the discourse salience of arms.  ...  Rodney Summerscales for providing us with the annotated corpus, and the anonymous reviewers for their helpful feedback.  ...
