We are glad to announce release 0.3 of MonaSearch. With this release,
MonaSearch has reached a level of usability which makes it interesting for
the wider community.

MonaSearch is a new powerful query tool for linguistic treebanks. The
query language of MonaSearch is monadic second-order logic, an extension
of first-order logic capable of expressing probably all linguistically
interesting queries. In order to process queries efficiently, they are
compiled into tree automata. A treebank is queried by checking whether the
automaton representing the query accepts the tree, for each tree.

Our experiments show that even complex queries can be executed very
efficiently using tree automata. The implementation includes a graphical
user interface to facilitate the composition of queries and the interaction
with treebanks. It uses the tree automaton toolkit MONA.

MonaSearch is freely available from the website:
