Lexical Semantics Toolkit & Dataset

The goal of this project is to provide easily usable models for lexical semantic relations, which have been developed at Microsoft Research. Currently the models include heterogeneous vector space models for measuring semantic word relatedness and the polarity inducing latent semantic analysis (LSA) model that judges whether two words or synonyms or antonyms.


This dataset contains various word vectors and lists for a variety of lexical semantic models. Measuring whether two words have a particular relation is typically very straightforward and can be done by computing the cosine score of the corresponding vectors. Information on how these vectors are created can be found in [Yih & Qazvinian, NAACL-HLT-2012] and [Yih, Zweig & Platt, EMNLP-CoNLL-2012]. Please refer to the ReadMe file for more detail of this dataset.
