Features
* (Jointly) visualize
o syntactic dependency graphs
o semantic dependency graphs (a la CoNLL 2008)
o Chunks (such as syntactic chunks, NER chunks, SRL chunks etc.)
* Compare gold standard trees to your generated trees (e.g. highlight false positive and negative dependency edges)
* Filter trees and visualize only what's necessary, for example
o only dependency edges with certain labels
o only the edges between certain tokens
* Search corpora for sentences with certain attributes using powerful search expressions, for example
o search for all sentences that contain the word "vantage" and the pos tag sequence DT NN
o search for all sentences that contain false positive edges and the word "vantage"
* Reads
o CoNLL 2000, 2002, 2003, 2004, 2006 and 2008 format
o Lisp S-Expressions
o Malt-Tab format
o markov thebeast format
* Export to EPS

Clojure is a dynamic programming language that targets the Java Virtual Machine. It is designed to be a general-purpose language, combining the approachability and interactive development of a scripting language with an efficient and robust infrastructure for multithreaded programming. Clojure is a compiled language - it compiles directly to JVM bytecode, yet remains completely dynamic. Every feature supported by Clojure is supported at runtime. Clojure provides easy access to the Java frameworks, with optional type hints and type inference, to ensure that calls to Java can avoid reflection.
Clojure is a dialect of Lisp, and shares with Lisp the code-as-data philosophy and a powerful macro system. Clojure is predominantly a functional programming language, and features a rich set of immutable, persistent data structures. When mutable state is needed, Clojure offers a software transactional memory system and reactive Agent system that ensure clean, correct, multithreaded designs.
I hope you find Clojure's combination of facilities elegant, powerful, practical and fun to use.
