To effectively and efficientlydiscover knowledge (business intelligence) from vast amount of textual information on the Web
Convenient storage hasmade information exploration difficult
Information is unreliable
Heterogeneity and unmonitored qualityof information on the Web
Hard to know all stakeholders
Interconnected nature of the Web complicates understanding of relationships
How can we develop an automatic text mining approach to address the problems of knowledge discovery on the Web?
How effective and efficient does such an approach assist human beings in discovering knowledge on the Web?
What lessons can be learned from applying such an approach in the context of human-computer interaction (HCI)?
