The BIUTEE Research Platform for Transformation-based Textual Entailment

(RTE) task shows a constantly-increasing level of complexity in this research eld. A way to avoid having this complexity becoming a bar-rier for researchers, especially for new-comers in the eld, is to provide a freely available RTE system with a high level of exibility and ex-tensibility. In this paper, we introduce our RTE system, BiuTee2, and suggest it as an effective research framework for RTE. In partic-ular, BiuTee follows the prominent transformation-based paradigm for RTE, and offers an accessible platform for research within this ap-proach. We describe each of BiuTee's components and point out the mechanisms and properties which directly support adaptations and integration of new components. In addition, we describe BiuTee's vi-sual tracing tool, which provides notable assistance for researchers in rening and \debugging " their knowledge resources and inference components.
