This paper presents a natural language analysis system LangLAB based on BUP-XG which parses with a bottom-up and depth-first strategy and has ability to handle left extraposition. We have already developed a grammar formalism XGS, which is a superset of DCG. With XGS, left extraposition phenomena is naturally expressed in grammar rules. We have also optimized BUP-XG clauses. Experiments showed that in comparison to the original BUP-XG system, the analysis sped up 10 times in the interpreter mode and 4 times in the compiled mode. The TRIE structured dictionary in LangLAB requires less memory, provides faster dictionary reference and also handles complicated idioms with versatility. Consequently, the utilization of LangLAB for practical purposes has become feasible.
