Course Descriptions
The increasing popularity of corpus-based linguistics has created a
need for (semi-)automatic tools that help with annotating and
searching a corpus. In this course we will focus on encoding
standards, e.g. XML, and techniques and tools for the following
annotation levels: tokenization, part-of-speech tagging and tagset
design, morphology, chunk parsing, and sytactic annotation.

Lexical Functional Grammar (LFG) and Head-Driven Phrase Structure
Grammar (HPSG) are widely perceived as closely related paradigms. Both
have developed much, though, since their inception, and there is
growing evidence that now they may differ more than they agree. The
aim of our course is to discuss the comparative strengths and
weaknesses of LFG and HPSG, focusing on their ontological
presuppositions, formal mechanisms, and the linguistic analyses they
propose for various linguistic aims.

Anna Kupsc: Slavic in HPSG
The aim of this course is to discuss some aspects of Slavic
languages and present analyses of these issues couched within the
constraint-based formalism of HPSG (Head-driven Phrase Structure Grammar).
The course is by and large based on the collection of papers in the volume
`Slavic in HPSG' B. Borsley and A. Przepiorkowski (eds.)
Detmar Meurers: Introduction to HPSG
This course is an introduction to some central empirical and
theoretical topics in the area of syntax. The theoretical
argumentation will be couched in the grammatical framework of
Head-Driven Phrase Structure Grammar (Pollard & Sag 1994), one of the
most active frameworks in the area of theoretical syntax as well as
computational linguistics. We will start with some fundamentals of
syntactic argumentation (e.g., constituent structure) and then turn to
the analysis of long-distance dependencies, raising and control
constructions, and the so-called binding theory.
Janina Radó: Introduction to Psycholinguistics
Kiril Simov, Gergana Popova: Computational Morphology
Morphological information is an essential part of any realistic
natural language processing task. In this course we present
an overview of the morphological phenomena found in different
natural languages and outline several computational paradigms
for processing morphological data. The course will also discuss
recent approaches to incorporating morphology into the framework
of HPSG.

Kiril Simov, Atanas Kiryakov: Declarative Knowledge Representation
We start with a discussion of basic notions like knowledge, reasoning
and knowledge representation (KR) from the point of view of theoretical
computer science. Next, we walk through the main components of KR
systems, and present the main ideas in declarative knowledge
representation such as conceptualisation of the world, kinds of
knowledge and reasoning, tractability, non-standard semantics,
prototypical knowledge, meta knowledge and meta reasoning, knowledge
communication. In the following lectures a few knowledge representation
languages are covered: KL-One, Knowledge Interchange Format, and
Conceptual Graphs. Finally, we devote some attention to the problem of
knowledge translation and interchange in a heterogeneous environment,
presenting a schema for automatic translation and the agent
communication language Knowledge Query and Manipulation Language.
Course Material
Kiril Simov, Atanas Kiryakov: WordNets: Principles and Applications
This course is based on "WordNet: An Electronic Lexical
Database"(Christiane Fellbaum, ed.), on other materials about the
EuroWordNet and GermaNet projects, and on the authors' works. First, we
make a general overview of the system: its assumptions, goals and
principles. Then we present the main semantic relations used in WordNet
for structuring the nets of the lexical concepts. Finally, several
applications of WordNet such as semantic tagging and information
retrieval are discussed.
