PDF-Measures of Distributional Similarity

Lee Department of Computer Science Cornell University Ithaca NY 148537501 cornell edu We study distributional similarity measures for the purpose of improving probability estima tion for unseen c. se 1 Introduction Distributional approaches to meaning acquisition utilize distributional proper ties of linguistic entities as the building blocks of semantics In doing so they rely fundamentally on a set of assumptions about the nature of language Input for Multidimensional Scaling and Clustering. Distances and Similarities. Both are ways of measuring how similar two objects are. Distances increase as objects are less similar. The distance of an object to itself is 0. .
