The European HLT-project NITE (Natural Interactivity Tools Engineering, 1.4.2001 - 31.7.2003) has built several toolsets for multi-level, cross-level and cross-modality annotation, retrieval and exploitation of multi-party natural interactive human-human and human-machine dialogue data. Two of the three NITE toolsets are freely available from these pages.

The three NITE toolsets are: NWB, the NITE WorkBench for Windows, NXT, the NITE XML Toolkit, and the commercial tool The Observer. Jointly, the NITE toolsets are becoming able to address the needs of all or most users who want to code (or annotate) and explore natural interactive and multimodal communication, including cross-level and cross-modality coding.

All three NITE toolsets continue to be developed and maintained after the end of the NITE project. For more information, please look up the individual tools.
