In scientific writing, positive credits and negative criticisms can often be seen
in the text mentioning the cited papers, providing useful information about
whether a study can be reproduced or not. In this study, we focus on citation
sentiment analysis, which aims to determine the sentiment polarity that the
citation context carries towards the cited paper. A citation sentiment corpus was
annotated first on clinical trial papers. The effectiveness of n-gram and
sentiment lexicon features, and problem-specified structure features for citation
sentiment analysis were then examined using the annotated corpus. The combined
features from the word n-grams, the sentiment lexicons and the structure
information achieved the highest Micro F-score of 0.860 and Macro-F score of
0.719, indicating that it is feasible to use machine learning methods for
citation sentiment analysis in biomedical publications. A comprehensive
comparison between citation sentiment analysis of clinical trial papers and other
general domains were conducted, which additionally highlights the unique
challenges within this domain.
