The OpenOffice.org Writer plug-in for the Semantic Assistants architecture provides for calling text analysis services directly from within the word processor. Results are either displayed as new documents or as annotations (using side-notes) on the existing document.

The Semantic Assistants project aims to bring natural language processing (NLP) techniques directly to end users by integrating them with common desktop applications (word processors, email clients, Web browsers, ...), web information systems (wikis, portals) and mobile applications (based on Android). To facilitate this integration, a service-oriented architecture has been developed that allows to integrate these clients with NLP services implemented in the GATE framework. NLP services are described with an ontology-based (OWL) semantic description that captures users, their languages, tasks, and various artifacts.

In the Semantic Assistants project, we investigate how to support users in content retrieval, analysis, and development, by offering context-sensitive NLP services directly integrated with common desktop applications (word processors, email clients, Web browsers, ...), web information systems (wikis, portals) and mobile applications (based on Android). They are implemented through an open service-oriented architecture, using Semantic Web ontologies and W3C Web Services.
