Probabilistic Relaxed Unification Formalism and Applications in Automated Question-Answering Systems
Reasoning about natural language requires robustness in the face of uncertainty about the validity of the information contained in the text. Many natural language processing formalism rely on classical unification, which assumes that the knowledge base is complete and accurate. However, this seldom applies to the real world; text from the Web may contain incorrect, incomplete, or contradictory information. We introduce probabilistic relaxed unification as an alternative approach where the assumptions of classical unification are relaxed. Relaxed unification replaces the binary success or failure outcome of classical unification with a real number quantifying the correctness of the result. Our formalism is realized in the implementation of a modular question-answering system prototype. Our approach is empirically validated through a series of cases drawn from real world questions and data collection. The validation cases substantiate that our system provides satisfactory results on the chosen dataset within the system limitations. This book should be of interest to academics and practitioners interested in reasoning under uncertainty and automated question-answering systems.
I was recently invited by VDM Verlag to publish my PhD dissertation as monograph. The way it works is that the author does all the work for preparing the manuscript, there is no editorial proof-reading or any type of content or formatting assistance. On the other hand, the publisher handles all the distribution and printing at no cost to the author. It’s a good deal if you’re looking for a low-risk (no cost to you) low-return publishing opportunity. The author receives some royalties, but they’re generally insignificant.
One significant difference between the book and the dissertation is the addition of an index. Learning about writing an index was both pleasant and frustrating, and it is my hope that the effort it took will prove of use to the reader.
The book is 156 page and available from Amazon at $84.00 USD. ISBN: 978-3639171402
