E-Commerce Intelligence and Mining
|
| Research
Goal |
 |
E-Commerce applications present unique challenges and opportunities for developing various data mining, text mining, and web mining techniques for business intelligence and knowledge management purposes. Based on more than one decade of research funded by NSF and other major commercial companies (HP, SAP, DEC, AT&T, CommerceOne, etc.), the University of Arizona Artificial Intelligence Lab has conducted E-Commerce Intelligence and Mining research in the following application areas:
Business Intelligence: Multilingual e-commerce portals and knowledge mapping systems;
Group Decision Support Systems (GDSS): Text mining and visualization to support collaboration;
Credit Rating: Data mining for international credit rating analysis;
ERP Knowledge Management: Knowledge mapping research for ERP content mining;
Patent Analysis: Text and citation based analysis of international patents;
E-Commerce Recommender Systems: Graph-based models for customer relation management (CRM) and product recommendation;
E-Commerce Security Analysis: Text and web mining for detecting fraudulent web sites and e-commerce contents;
Stock Prediction Systems: Text mining based stock outbreak detection;
E-Commerce Marketing and Survey: Opinion mining for Web 2.0 customer-generated contents and sentiment analysis.
