Natural Language Interaction With Dynamic Knowledge Bases

This book constitutes the refereed proceedings of the 5th International Workshop on Controlled Natural Language, CNL 2016, held in Aberdeen, UK, in July 2016. The 11 full papers presented were carefully reviewed and selected from 15 submissions. The topics range from natural languages which are controlled, to controlled languages with a natural language flavour; and from more theoretical results to interfaces, reasoning engines and real-life applications of CNLs.

Computational Linguistics provides an overview of the variety of important research in computational linguistics in North America. This work is divided into 15 chapters and begins with a survey of the theoretical foundations and parsing strategies for natural language. The succeeding chapters deal with psychological and linguistic modeling, discourse processing analysis, text and content analysis, and natural language understanding, as well as knowledge organization, memory models, and learning. Other chapters describe the programming systems and considerations for computation linguistics. The last chapters look into the nature of natural language front-end processes to database systems. These chapters also examine the human factors interface. This book will prove useful to computing scientists, philosophers, psychologists, and linguists.

In almost all principled accounts of questions questions are related to the corresponding answers. Zellig Harris (Harris 1978:1), for example, maintains that" ... all interrogative sentences can be derived, by means of the independently established transformations of the language, from sentences which assert that someone is asking about a disjunction of statements which are the relevant possible answers to that interroga tive." This amounts to the claim that a yes-no question such as Will John stay? is derived from I ask you whether John will stay and a wh question such as Who came is derived from something like I ask you whether A came or B came or ... or X came .. Though in generative grammar interrogatives are not derived from the corresponding declaratives, the semantic interpretation of questions is akin to the syntactic source of questions posited by Harris. Jerrold J.Katz and Paul M.Postal (Katz-Postal 1964:113-117) state a reading rule for Q, the interrogative constituent, which boils down to (1) in the case of yes-no questions and to (2) in the case of wh-questions. (1) Tell me which of the following is true: John will stay or John will not stay. (2) Tell me which of the following is true: A came or B came or ... or X came. Thus, the semantic interpretation of questions makes reference to the set of possible answers represented here by a disjunction of statements.

Papers direct the focus of interest to the development and use of conceptual models in information systems of various kinds and aim at improving awareness about general or specific problems and solutions in conceptual modelling.

Explorations in Automatic Thesaurus Discovery presents an automated method for creating a first-draft thesaurus from raw text. It describes natural processing steps of tokenization, surface syntactic analysis, and syntactic attribute extraction. From these attributes, word and term similarity is calculated and a thesaurus is created showing important common terms and their relation to each other, common verb--noun pairings, common expressions, and word family members. The techniques are tested on twenty different corpora ranging from baseball newsgroups, assassination archives, medical X-ray reports, abstracts on AIDS, to encyclopedia articles on animals, even on the text of the book itself. The corpora range from 40,000 to 6 million characters of text, and results are presented for each in the Appendix. The methods described in the book have undergone extensive evaluation. Their time and space complexity are shown to be modest. The results are shown to converge to a stable state as the corpus grows. The similarities calculated are compared to those produced by psychological testing. A method of evaluation using Artificial Synonyms is tested. Gold Standards evaluation show that techniques significantly outperform non-linguistic-based techniques for the most important words in corpora. Explorations in Automatic Thesaurus Discovery includes applications to the fields of information retrieval using established testbeds, existing thesaural enrichment, semantic analysis. Also included are applications showing how to create, implement, and test a first-draft thesaurus.

Applications of Natural Language to Information Systems covers high academic quality papers on the following topics: natural language interfaces to databases, information retrieval, use of linguistic tools and electronic dictionaries, conceptual modelling, paraphrasing and validating information system models, the use of natural language as a specification interface for the design of information systems, linguistic aspects of database view integration and hypertext facilities for database querying. Furthermore the typical applications of natural language, are addressed, presented both from a scientific as well as an industrial perspective by Peter Chen, the inventor of the ER model, and Gerald Kristen, the founder of the KISS company. Other topics: - Natural Language Specification; - Natural Language Paraphrasing; - Linguistic Tools and Electronic Dictionaries; - Database Hypertext Facilities; - Information Retrieval; - Natural Language Database Interfaces; - Conceptual Modeling with Linguistic Knowledge; - Linguistic Aspects of Database View Integration.
