Book
Contents
The first
chapter of this book describes the process of representing the meaning of
an input query in the constructed formal language. Following the
rule-based semantic analysis for natural language questions and
definitions, accompanying topics are presented such as the concept of
vertical domain, syntactic analysis, first-order language and its meta
language extensions, as well as the architecture of semantic processor,
formal semantics models and grammars relevant to our pragmatic
approach.
The second
chapter introduces the process of matching the formal representation of an
input query with the formalized domain knowledge in the way of semantic
headers. The task of query understanding is posed for the
hardly-formalized and poorly structured domains with textual answers.
Knowledge representation methodology and associated semantic peculiarities
are discussed; coding patterns are introduced for the technique of
semantic headers.
The third
chapter addresses the practical issues of implementing question answering
domains. Various topics are discussed from marketing, programming styles
and development to deployment and maintenance of question answering
applications, as well as management of the team of knowledge engineers,
experts and testers. Multiagent implementation, various knowledge domains,
the software project structure and development tools are also
presented.
The fourth chapter
introduces the reasoning mechanism as the background of the suggested
approach to Q/A, particularly, scenario-based reasoning about mental
attitudes. Default logic is used for correction of the semantic
representations.
