The Dragon ToolKit
|
| Designed for Languge Modeling and Information
Retrieval |
| 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. |

| The Examples for Development |
| To help developers get on the track of programming with the Dragon
Toolkit, we provides some examples for different applications: (1)
MaxMatcher (Biolgoical Term Extraction),
(2) Text Retrieval (Language Modeling
Information Retrieval with Semantic Smoothing), and (3) Text
Clustering (Model-based Document Clustering with Semantic Smoothing). |
