3 B09 Parsing Systematic overview of the tasks of a computer program for syntactic analysis. Algorithms that tackle these tasks and their alternatives. Overview over prototypical parsers, e.g. recursive-descent parsers, Earley parsers, the Cocke/Kasami/Younger parser, table-controlled shift reduce parsers, finite-state parsers, augmented transition networks, or slot-and-filler parsers for dependency grammars. Efficiency measures. evaluation criteria. B10 Pragmatics and Text Linguistics Introduction to speech act theory, speech act sequences. Conversational postulates. Concepts and methods of discourse structuring on the levels of text and of dialog. Syntagmatic connectivity (cohesion) and pragmatic connectivity (coherence). Coherence in monological texts, implicit question-answer-relations, rhetorical structure theory, cue phrases. Cohesion based on coreference, predicate-based connectivity, contiguity. Relation between text and sentence structure. Information structure: theme-rheme, topic-comment, background-focus. Ways of modelling this information that enable the computer to process natural language dialogue and text, or to produce them. B11 Logic Some mathematical foundations (set theory, algebra). Propositional calculus, first order predicate calculus. 2 Core Modules A01 Course in Computer Science 9 ECTS Credits A course from the Computer Science curriculum chosen at the student s discretion.

Pattern matching. Planing, search strategies, heuristics. Deduction, induction and abduction, non-monotonic reasoning, fuzzy logic. Connectionist networks. A06 Prolog Introduction to logic programming, with an emphasis on syntax parsing, knowledge representation and inference. Example applications from natural language processing and artificial intelligence. A07 Sentence Semantics Phenomena of sentence semantics (those connected to syntax and syntactic phenomena as opposed to lexical and referential phenomena). Mostly concerned with semantic relations between sentences (such as paraphrase, implication, presupposition). The concept of truth conditional semantics or the logical form of language. Introduction to advanced concepts in logics (modal logics, type theory, lambda expressions etc.). Translation of parts of expressions in natural language into logical language and composition of these translations through suitable operations. Syllogistic approaches, modelling of logical semantics through operations on the syntactic level (cf. transformation grammar). A08 Text Semantics A comprehensive overview of how text meaning is constructed. The course is a sequel to Pragmatics and Text Linguistics and further develops the skills obtained there. The most important computational approaches in the field are also discussed.
