Abstract
A hierarchical model incorporating motion patterns, proto symbols and words is proposed. The proto symbols abstract motion patterns, while the words are associated with the proto symbols stochastically. This paper describes the construction of a word space, where words are located in a multidimensional space based on dissimilarities among the words. The dissimilarity between two words can be calculated by using association probabilities that the words generate motion proto symbols. The word space encapsulates relations among the words such as similar or dissimilar pairs of words. The word space also allows motion recognition based on words. The validity of the constructed word space is demonstrated on a motion capture database. Moreover, the addition of the word associations is found to change the conventional proto symbol space so that the discrimination among the proto symbols is improved.
