Citation Classification for Behavioral Analysis of a Scientific Field
Table 2: Citation class distribution in the dataset
['[BOLD] Citation Function', '[BOLD] Count', '[BOLD] % Positioning', '[BOLD] % Essential']
While some citation functions are strongly associated with one centrality type, e.g., Background as Positioning; citation function does not wholly predict centrality, highlighting the need for the two complementary classifications. Data Annotated data is crucial for developing high accuracy for rare citation classes. Therefore, we integrate portions of the dataset of \newciteteufel2010structure, which has fine-grained citation function labeled for ACL-related documents using the annotation scheme of \newciteteufel2006automatic. We map their 12 function classes into six of ours. When combining the two datasets, we omit the data labeled with their Background-equivalent class to reduce the effects of a large majority class and because instances of the Future class are merged into Background according to their scheme. The resulting citation function dataset contains 3083 instances. As there is no precise mapping from function to centrality (cf.
