- QUOTE: The window-wise co-occurrence statistic is an even narrower notion of context, considering only terms in a window surrounding [math]\displaystyle{ w' }[/math]. Specifically, a window of a fixed size is moved along the text, and [math]\displaystyle{ f_{ww'} }[/math] is set as the number of times both [math]\displaystyle{ w }[/math] and [math]\displaystyle{ w' }[/math] appear in the window. Since the window size is a free parameter, different sizes may be applied. In our experiments we use two window sizes, 2 and 5, that have been studied in related research (Church and Hanks, 1990).
