Ontology-based Multimodal User Interface in MOQA AQUAINT 18-Month Workshop San Diego, California Tanya Korelsky Benoit Lavoie Ted Caldwell CoGenTex, Inc.
Goals of MOQA Interface • To enable the analyst in ergonomic browsing of an information-rich, ontology based repository • To facilitate justification of search results and production of session reports CoGenTex, Inc.
Interface Features • Support for both natural language (NL) queries and structured queries used for validation of NL queries • Intuitive web-based multimodal interface for answers (search results) • Tables, text, maps, timeline, and social network graphs interconnected by hyperlinks • Natural language generation used in answers, answer justification, and for query validation • Implemented using XML-based technology CoGenTex, Inc.
MOQA User Interface:Accomplishments since December 2002 Workshop • Implemented all features shown in mockup at December 2002 Workshop • Incorporated all the feedback given at Workshop • All the modalities in place, including integrated third party software, MapObjects from ESRI and Graph Editor Toolkit from Tom Sawyer Software. • Fully integrated with the MOQA Fact Repository and working as a live system over the Internet and at the sites CoGenTex, Inc.
Benefits of Textual Summaries • Textual descriptions complement graphics and tables by • highlighting salient facts and events • clustering data in meaningful ways • Hypertext enables web-based data exploration via “drilldown” • Text plays a crucial role in • search results justification when search involves inference • session report production CoGenTex, Inc.
CoGenTex’s NLG Expertise • R&D for MOQA builds on and extends capabilities developed in previous efforts: • Web-based multimodal presentations which include automatically generated summaries • Generic text plans which support portability between subject domains • Explanation of expert system reasoning CoGenTex, Inc.
Query Interface • Integrates with the NL question processor, which builds Text Meaning Representations (TMRs). • Produces a corresponding structured query, to validate the NL question, and automatically paraphrases it in a disambiguated form of language. • Paraphrases are a crucial feature of the planned ontology-based query clarification and repair dialogs CoGenTex, Inc.

Underlying XML Query • Use standard XML technology (browser, parsers, etc.) • Support for : • Modularity: XML representation is viewable and exchangeable between subsystems • Automatic validation of query instances using a query class hierarchy described by XML schemas • Complex queries via use of logical expressions in XML CoGenTex, Inc.
Validation of NL Query CoGenTex, Inc.
Results Page Highlights • Multimodal display with table, timeline, text, map, and relationship diagram • Hyperlinks for drilldown • Textual summaries highlight patterns in results (prompts for sorting/ filtering table) CoGenTex, Inc.

Session History • Captures sequence of queries and results • Analyst can reorder/delete items to retain most important info • Reports can be exported to text editor CoGenTex, Inc.

R&D Plans for next 6 months • Presentation of ontology-based inference for result justification • Intelligent maintenance of session history and retrieved material to facilitate report production • Presentation of search results for partially understood natural language queries • Exploration of interface portability between subject domains based on automatic generation of interface core from the subject domain ontology CoGenTex, Inc.
MOQA User Interface: Validation • Validation by domain experts is crucial for producing an intelligent and ergonomic question answering interface • Highly interconnected multimodality offers new views on data and methods of browsing • Feedback is crucial • for the search results justification • for session report production CoGenTex, Inc.
