To replicate Foltz et al. (1998) , software was written in Java that created a moving window of varying sizes on the input text, and the software retrieved the LSA vector and calculated the cosine of each window. Hearst (1994<cite> Hearst ( , 1997</cite> was replicated using the JTextTile (Choi, 1999 ) Java software. A variant of Hearst (1994<cite> Hearst ( , 1997</cite> was created by using LSA instead of the standard vector space method.
