Nanotechnology holds the promise of revolutionizing a wide range of application areas and has been recognized by most countries as critical to a nation's future technology competence. Increased funding and research have generated a growing number of patents and an increase in the amount of literature available. Government interest, funding levels, industry investment, and active research activities have created a greater need to monitor global development of Nanoscale Science and Engineering (NSE) and the R&D status in industry and academic institutions, and to understand the impact of the funding in the NSE field. The research directions of the Artificial Intelligence Lab include:
- Development of the patent analysis framework for worldwide NSE R&D status.
- In-depth grant-patent association analysis to assess the impact of NSF funding and NSF-funded researchers in NSE field.
- Comparative study of the NSE patents issued by multiple patent offices.
- Assessment of NSE research in academia using scientific literature and comparison with industries' efforts as represented by patents.
- Citation network topological analysis for knowledge diffusion trend identification.
- Text mining based methods for research topic identification and topic burst identification.
- Development of an integrated NanoMap system for NSE patent and literature retrieval, analysis, and visualization.

- European Patent Office (EPO) NSE patent data (1978-2008) searched by domain expert who provided keywords on title and abstract.
- Japan Patent Office (JPO) NSE patent data (1976-2008) searched by domain expert who provided keywords on title and abstract.
- National Science Foundation (NSF) NSE grant data (1989-2008) searched by domain expert who provided keywords on : grant title, program, and abstract.
- Thomson Science Citation Index Expanded (SCIE) NSE literature data (1976-2007) searched by domain expert who provided keywords on title, paper keywords, and abstract.
- Basic bibliographic analysis on the key indicators of technology development performance
- Content map analysis
1) Using the Arizona Noun Phraser-indexing and Kohonen self-organization map (SOM) algorithm to compare and associate the main topic areas.
2) Longitudinal content map analysis visualizes the change of topic areas in terms of time periods.
- Citation network analysis
1) Network visualization: Graphviz, an open source graph drawing software, provided by AT&T Labs (Gansner and North, 2000) (available at:http://www.research.att.com/sw/tools/graphviz/).
2) Network visualization: NetDraw, a free network drawing program by Steve Borgatti (available at: http://www.analytictech.com/downloadnd.htm)
3) Network topological analysis: Using the social network analysis method to study the patterns in citation networks, the topological measures of the citation networks and their implications.
