Zusammenfassung
As multimodal data becomes easier to record and store, the
question arises as to what practical use can be made of archived corpora,
and in particular what tools allowing efficient access to it can be
built. We use the AMI Meeting Corpus as a case study to build an automatic
content linking device, i.e. a system for real-time data retrieval.
The corpus provides not only the data repository, but is used also to
simulate ongoing meetings for development and testing of the device.
The main features of the corpus are briefly described, followed by an
outline of data preparation steps prior to indexing, and of the methods
for building queries from ongoing meeting discussions, retrieving elements
from the corpus and accessing the results. A series of user studies
based on prototypes of the content linking device have confirmed the relevance
of the concept, and methods for task-based evaluation are under
development.
