The Dragon ToolKit for Languge Modeling and Information Retrieval (archive)
This java development toolkit for language modeling and info retrieval is from Data Mining & Bioinformatics Lab at Drexel University (Dr.Xiaohua Tony Hu lab).
Introduction:
The Dragon Tooolkit is a cute Java-based development package for academic research use in langaguge modeling (LM) and information retrieval (IR). Language modeling has recently emerged as an attractive new framework for text information retrieval and text mining (TM). However, most Java-based free search engines such as Rucene does not support LM very well. The Lemur toolkit is designed for LM and IR, but written in C and C++, which may be a hindrance to people who prefer Java programming. Basically, the dragon toolkit is tailored for researchers who work on large-scale LM and IR and prefer Java programming. Moreover, different from Lucene and Lemur, it provides built-in supports for semantic-based IR and TM. The dragon tookit seamlessly intergrates and implements a set of NLP tools, which enable the toolkit to index text collections with various representation schemes including words, phrases, ontology-based concepts and relationships. However, to minimize the learning time, we intentionally keep the package small and simple. The toolkit does not have some features including distributed IR and cross-language IR which are part of Lemur toolkit.
