This book constitutes the refereed proceedings of the 9th International Conference on Language
and Automata Theory and Applications LATA 2015 held in Nice France in March 2015. The 53
revised full papers presented together with 5 invited talks were carefully reviewed and
selected from 115 submissions. The papers cover the following topics: algebraic language theory
algorithms for semi-structured data mining algorithms on automata and words automata and
logic automata for system analysis and program verification automata networks concurrency
and Petri nets automatic structures cellular automata codes combinatorics on words
computational complexity data and image compression descriptional complexity digital
libraries and document engineering foundations of finite state technology foundations of XML
fuzzy and rough languages grammatical inference and algorithmic learning graphs and graph
transformation language varieties and semigroups parallel and regulated rewriting parsing
patterns string and combinatorial issues in computational biology and bioinformatics string
processing algorithms symbolic dynamics term rewriting transducers trees tree languages
and tree automata weighted automata.
