Inter-word associations like stagger -drunken, or intra-word sense divisions (e.g. write a diary vs. write an article) are difficult to compile using a traditional lexicographic approach. As an alternative, we present a model that reflects this kind of subtle lexical knowledge. Based on the minimal sense of a word (clique), the model (1) selects contextually related words (contexonyms) and ( 2 ) classifies them in a multi-dimensional semantic space. Trained on very large corpora, the model
