Available in PDF, EPUB and Kindle. Book excerpt: The principal concern of the thesis is to develop an approach to the parsing of natural language which uses as much parallel computation as possible on a standard computer. This approach exploits data structures based on machine-word-level binary representations to provide fast ways to implement the time-consuming data-combining operations which are required during parsing. The practical research centres on grammars in two forms; Context Free Grammars and Definite Clause Grammars. The thesis describes algorithms for parsing both sorts of grammar, and the practical performance of software implementing these algorithms is examined. The thesis shows how in online chart-parsing algorithms left-context filtering can be imposed with very little overhead, using binary techniques. The method is illustrated using a CFG taken from Tomita's exposition of his well-known nondeterministic LR parsing method. CFG parsing provides a foundation in the thesis for the treatment of Unification Grammars by means of a context-free skeleton. Machine-word-level binary techniques of achieving left-context filtering continue to be used in the UG chart parser developed in the later part of the thesis. A binary method of representing features and their values is also exploited, allowing very fast unification. The object form of the ANLT unification grammar, an example of DCGs, is employed to test the author's software which uses these binary data structures. The software achieves a considerable speed-up in the parsing process when compared with other published results. The results section is followed by a number of suggestions for further enhancing performance.

Available in PDF, EPUB and Kindle. Book excerpt: In this dissertation, it is shown that declarative, feature-based, unification grammars can be used for efficiently both parsing and generation. It is also shown that radically different algorithms are not needed for these two modes of processing. Given this similarity between parsing and generation, it will be easier to maintain consistency between input and output in interactive natural language interfaces. A Prolog implementation of the unification-based parser and DAG unifier is provided. The DAG unifier includes extension to handle disjunction and negation. The parser presented in this thesis is based on Stuart Shieber's extensions of Earley's algorithm. This algorithm is further extended in order to incorporate traces and compound lexical items. Also, the algorithm is optimized by performing the subsumption test on restricted DAGs rather than on the full DAGs that are kept in the chart. Since the subsumption test can be very time consuming, this is a significant optimization, particularly for grammars with a considerable number of (nearly) left recursive rules. A grammar which handles quantifier scoping is presented as an example of such a grammar. For generation, the algorithm is modified in order to optimize the use of both top-down and bottom-up information. Sufficient top-down information is ensured by modifying the restriction procedure so that semantic information is not lost. Sufficient bottom-up information is ensured by making the algorithm head-driven. Generation also requires that the chart be modified so that identical phrases are not generated at different string positions. It is shown how readjustments to the chart can be made whenever a duplicate phrase is predicted. The generator in this thesis does not perform equally well with all types of grammars. Grammars employing type raising may cause the generator to go into an unconstrained search. However, given the independently motivated principles of minimal type assignment and type raising only as needed, it is shown how such unconstrained searches can be avoided. Finally, suggestions are made as to how unification grammars can be developed in order to handle difficult problems such as partially free word order, bound variables for semantic interpretation and resolving feature clashes in agreement.

Available in PDF, EPUB and Kindle. Book excerpt: "Modern Compiler Design" makes the topic of compiler design more accessible by focusing on principles and techniques of wide application. By carefully distinguishing between the essential (material that has a high chance of being useful) and the incidental (material that will be of benefit only in exceptional cases) much useful information was packed in this comprehensive volume. The student who has finished this book can expect to understand the workings of and add to a language processor for each of the modern paradigms, and be able to read the literature on how to proceed. The first provides a firm basis, the second potential for growth.

Available in PDF, EPUB and Kindle. Book excerpt: Maude is a language and system based on rewriting logic. In this comprehensive account, you’ll discover how Maude and its formal tool environment can be used in three mutually reinforcing ways: as a declarative programming language, as an executable formal specification language, and as a formal verification system. Examples used throughout the book illustrate key concepts, features, and the many practical uses of Maude.
