Tabulation techniques are becoming a common way to deal with highly redundant computations occurring, for instance, in Natural Language Processing, Logic Programming, Deductive Databases, or Abstract Interpretation, and related to phenomena such as ambiguity. non-determinism, or domain ordering.
Different approaches, including for example Chart Parsing, Magic-Set rewriting, Memoization, and Dynamic Programming, have been proposed whose key idea is to keep traces of computations to achieve computation sharing and loop detection. In addition, tabulation also offers more flexibility to investigate new parsing or proof strategies and to represent ambiguity by shared structures (Shared Proof or Parse Forest).
The first objective of this workshop is to compare and discuss these different approaches. The second objective is to present tabulation and tabular systems to potential users in different application areas. One major area of application is Natural Language Processing, where tabulation has been known for a long time (CKY, Earley, chart parsing). However, sophisticated tabulation techniques are required for the more and more complex grammatical formalisms now used in NLP (unification, constraints, structural complexity). Contributions in other areas, such as picture parsing, genome analysis, or complete deduction techniques, are also encouraged.
The collection of selected papers will be available at the workshop. After the workshop, authors are invited to submit a full paper for publication in a special issue of the Journal of Logic Programming oriented towards Natural Language Processing. The authors should note that this second submission will be treated according to the standards of the Journal of Logic Programming.
