The NITE XML Toolkit (NXT) provides library support for working with multimodal language corpora. We describe work in progress to explore its potential for the AMI project by applying it to the ICSI Meeting Corpus. We discuss converting existing data into the NXT data format; using NXT’s query facility to explore the corpus; hand-annotation and automatic indexing; and the integration of data obtained by applying NXT-external processes such as parsers.
