Prerequisites
Students are strongly adviced to bring some basic knowledge of automata theory (IB005) and natural language processing (IB030 or IB047). Some database basics (PB154) will be helpful as well.

Course objectives
Basic techniques and algorithms used in textual information systems are taught. That means text search algorithms (KMP, AC, BM, RK, ...), data structures used for index storage, query languages, architecture of textual information system that uses natural language processing techniques.

Assessment methods (in Czech)
Výuka probíhá klasickým způsobem a je zakončena písemným testem (tvoří 70 % hodnocení). Příklady testů z předchozích let jsou vystaveny na webu předmětu. 30 % závěrečného hodnocení tvoří hodnocení písemek zadávaných v průběhu semestru na cvičeních. Na cvičeních dochází k procvičování látky z přednášek, k brainstormingu. V průběhu výuky jsou studenti motivováni dílčími úkoly honorovanými udělením prémiových bodů.
