How semantic is Latent Semantic Analysis
Tonio Wandmacher, Site de Blois · 2005
In the past decade, Latent Semantic Analysis (LSA) was used in many NLP approaches with sometimes remarkable success. However, its abilities to express semantic relatedness were not yet systematically investigated. This is the aim of our work, where LSA is applied to a general text corpus (German newspaper), and for a test vocabulary, the lexical relations between a test word and its closest neighbours are analysed. These results are compared to the results from a collocation analysis.
