EDAN20 – Language Technology

The schedule for August/October 2011 is available here: https://web.timeedit.se/lu_sls/db1/timeedit/p/lth1/reservations.html?base=c2lkPTEwMDkmb2JqZWN0cz0xNjEzODMuMTgzJm94PTAmdHlwZXM9MCZmZT0w

Due to a meeting in Gothenburg on September 13, 2011, the class is cancelled for this date (13/09/2011). It will be replaced by a lecture on September 23, room E:B.

The course takes place in the HT1 "study period".

Objectives

The course introduces theories and techniques of natural language processing and language technology. It attempts to cover the whole field from speech recognition and synthesis to semantics and dialogue.

It focuses on industrial or laboratory applications, such as document retrieval on the Internet, information extraction, conversational agents, and verbal interaction in virtual worlds. Fundamental algorithms will be described using Prolog or regular expressions.

Course contents

An overview of language processing: presentation of language processing, applications, disciplines of linguistic, examples
Corpus and word processing: regular expressions, automata, an introduction to Perl, concordances, tokenization, counting words, collocations
Morphology and part-of-speech tagging: morphology, transducers, part-of-speech tagging,
Prolog to write phrase-structure grammars: constituents, trees, using Prolog to do natural language analysis, DCG rules, variables, getting the syntactic structure, compositional analysis to get the semantic structure.
Syntactic formalisms: constituency and dependency, chart parsing, statistical parsing, functions, dependency parsing.
Semantics: formal semantics, lambda-calculus, compositionality: nouns, verbs, determiners, words and meaning, lexical semantics, case grammars, semantic grammars
Discourse and dialogue: discourse and rhetoric, anaphora, structure, RST, dialogue: automata, pairs, speech acts, multimodality.
Overview of speech synthesis and speech recognition
