Abstract: The CONCERTO project, primarily concerned with the annotation of texts for their conceptual content, combines automatic linguistic analysis with manual annotation to ensure the accuracy of fact extraction, and to encode content in a rich knowledge representation framework. The system provides annotation tools, automatic multi-level linguistic analysis modules, a partial parsing formalism with a more user friendly language than standard regular expression languages, XML-based document management, and a powerful knowledge representation and query facility. We describe the architecture and functionality of the system, and how it can be adapted for a range of resource construction tasks, and how the system can be configured to compute statistics on the accuracy of its automatic analysis components.
