Yorick Wilks is a central figure in the fields of Natural Language Processing and Artificial Intelligence. This set consists of a volume of selected papers and a volume with contributions from his peers. The first book offers a selection of papers by Yorick Wilks, which are intended to reflect the range and depth of his work. The papers include early work carried out at Cambridge University, descriptions of groundbreaking work on Machine Translation and Preference Semantics as well as more recent works on belief modeling and computational semantics. The selected papers reflect Yorick's contribution to both practical and theoretical aspects of automatic language processing. The second volume celebrates the work of Yorick Wilks from the perspective of his peers. It consists of original chapters each of which analyses an aspect of his work and links it to current thinking in that area. His work has spanned over four decades but is shown to be pertinent to recent developments in language processing such as the Semantic Web.
