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

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
