Analysis of word embeddings and sequence features for clinical information extraction
De Vine, Lance, Kholghi, Mahnoosh, Zuccon, Guido, Sitbon, Laurianne, & Nguyen, Anthony (2015) Analysis of word embeddings and sequence features for clinical information extraction. In 13th Annual Workshop of the Australasian Language Technology Association, 8 - 9 December 2015, University of Western Sydney, Parramatta, NSW.
This study investigates the use of unsupervised features derived from word embedding approaches and novel sequence representation approaches for improving clinical information extraction systems. Our results corroborate previous findings that indicate that the use of word embeddings significantly improve the effectiveness of concept extraction models; however, we further determine the influence that the corpora used to generate such features have. We also demonstrate the promise of sequence-based unsupervised features for further improving concept extraction.
Impact and interest:
Citation counts are sourced monthly from and citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
Full-text downloads displays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
