The book by Mel~uk (1988) presents a comprehensive exposition of dependency syntax. Computational approaches to dependency syntax have recently become quite popular (., a workshop dedicated to computational approaches to dependency grammars has been held at COLING/ACL'98 Conference). J~irvinen and Tapananinen have demonstrated an efficient wide-coverage dependency parser for English (Tapanainen and J~irvinen, 1997; J£rvinen and Tapanainen, 1998). The work of Sleator and Temperley(1991) on link grammar, an essentially lexicalized variant of dependency grammar, has also proved to be interesting in a number of aspects. .
