This book is dedicated to Professor Leonard Bole on the occasion of his 75th
birthday, and contains essays written by his friends, former students and col-
leagues to celebrate his scientific career. For many years Leonard Bole has played
an important role in the Polish computer science community. He was especially
known for his clear vision in the development of artificial intelligence, inspiring
research, organizational and editorial achievements.
The papers included in this volume, present research in the areas which
Leonard Bole and his colleagues investigated during his long scientific career,
i.e., logic, automatic reasoning, natural language processing, and computer ap-
plications of natural language or human-like reasoning.
Part I of the book is devoted to logic the domain which was one of the most
explored by Leonard Bole himself. The first paper in this section describes a new
approach to making correct judgments keeping in mind real-world constraints.
The second paper addresses the problem of qualitative interpretation of fuzzy-
like para consistent reasoning with natural language words.
Part II contains papers focusing on different, aspects of computational linguis-
tics. This part begins with papers devoted to morphology. Two of them describe
morphological aspects of the Polish and Uzbek languages, and the third paper
discusses morphological properties of Polish multi-word proper names. The sub-
sequent paper presents a new definition of Polish nominal phrases defined within
the metamorphosis grammar formalism, which was first described in one of the
numerous publications edited by Professor Bole. The following four papers are
devoted to automatic acquisition of linguistic knowledge: extraction of semantic
relations, valence dictionaries, and semantic restrictions on verb arguments.
Part III comprises papers describing different applications in which natural
language processing or automatic reasoning plays an important, role. The first,
paper is devoted to speech technology and describes the issues of voice portal
implementation. Speech analysis was a subject, of interest to Professor Bole in
the mid-1970s, which is commemorated in the following paper. The next two
papers are devoted to different aspects of information extraction. The first, one
presents real-time event extraction, whereas the next one describes the creation
of a domain model for information extraction applications in the medical domain.
The next topics addressed are methods of searching for exact, and approximate
patterns in texts, and decision making in the context of a support system that is
capable of dynamically adjusting its prediction model. The last paper presents
an environment that allows a group of professional analysts to work together on
complex problems and exchange their results in active and tacit ways.l
