Advanced Topics on Weighted Tree Automata im Wintersemester 2013/2014 (nur auf Englisch)In many areas of Computer Science trees are used to structure data and to represent hierarchical dependencies between parts of data; for instance, the structure of a sentence of a natural language is represented as a tree (parse tree). Hence, it is of general interest to provide algorithms and machines which decide whether trees have certain properties, rank trees by associating a weight with each of them, or transform trees into other trees. Taking up the natural language scenario, it is e.g. important to know the probability that a sentence is well-structured with respect to some grammatical rules, or what the possible translations of a sentence of one language into another language are. Weighted tree automata are appropriate structures for such algorithms. In this lecture we will introduce their basic definitions and properties on a theoretical level, however keeping the application to natural language processing in mind. Schedule
The first lecture will take place on Monday, October 14. Literature
ExercisesThe tutorial's time might not suffice for presenting all solutions. Please prepare to ask for the solutions you are most interested in.
