The model is based on a distributional representation of meaning that draws on work on automatically clustering similar words (Lin, 1998) that has been incorporated into tools used by lexicographers to identify word senses (Kilgarriff and Tugwell, 2002).
this method measures the similarity of two lexico-syntactic representations of the aggregated contexts of a target word; these two representations would typically come from different corpora representing, for example, different time periods.
