My Own Research
• From Algorithms to Information Retrieval
• Information Mining Model
• Image Retrieval: WebFaces
• Web Mining– Crawling– Web Characterization & Dynamics– Impact on Search Engines and vice versa– Improving Web Sites– Query Mining

WebFaces: Resultado
Web Structure: Crawling
Static vs. Dynamic pagesPublic vs. Hidden pages

How to Improve Web Design?
• User-driven design by Web mining• Analysis of navigation logs
– Improve organization
• Analysis of query logs (local site search)– Improve content and semantics of your text
Navigation Mining: Site Restructuring
Query Mining: Information Scent
Content & Structure Mining
• Correlate Text Content with Link Structure– Text Clustering– Link Analysis
• Tool for Query, Content and Structure Mining in Web Sites
