Detecting Patterns in the LSI Term-Term Matrix
April Kontostathis, William M. Pottenger · 2002
applications use techniques that explicitly or implicitly employ a limited degree of transitivity in the co-occurrence relation. In this work we show use of higher orders of co-occurrence in the Singular Value Decomposition (SVD) algorithm and, by inference, on the systems that rely on SVD, such as LSI. Our empirical and mathematical studies prove that term cooccurrence plays a crucial role in LSI.
