On the Feasibility of Automated Detection of Allusive Text Reuse
Table 4: Comparison of best performing approach SCemb across different segmentation types: manual and automatic window of 3 (Win-3) and 10 (Win-10) tokens to each side of the anchor word.
['Metric', 'Lemma', 'Segmentation Manual', 'Segmentation Win-3', 'Segmentation Win-10']
A window of 10-word around the anchor produces slightly better results than a 3-word window -- more closely matching the overall mean length of manually annotated queries. This indicates the importance of localizing the appropriate set of referential words in context, while avoiding the inclusion of confounding terms.
