• Describe the growing problem with general search engines

Growing Problem
• Web has plenty of useful resources• Dynamic, unstructured nature makes them
difficult to locate• Number of Web pages exceeds 20 billion• General search engines cannot maintain
comprehensive, up-to-date search indexes• Web growth Information overload in query
results• General search engine generates thousands of
hits, many irrelevant to the user query
Growing Problem
• ~80 percent of American Internet users search the Web for health information– 95 million Americans
• > 70% did not find what they wanted or did not know what to believe
Jupiter Research - Aug 2006
Growing Problem
• Most Internet users start at a general search engine when researching health & medical advice online
• Check the source and date of online health information:– 15% - “always”– 10% - “most of the time”– 75% - “only sometimes” “hardly ever” or “never”
• 85 million Americans gather health advice online without consistently examining the quality indicators of the information they find

Vertical Search Engines (VSE)
• Vertical search engines solve part of the problem
• Specialized search technologies that focus on narrow niches
• Engines that search only narrow niche of Web are more convenient & effective for the user
• Face the challenge of collecting set of relevant, high-quality pages from Web
• Demand for high-quality pages is generally more important in vertical search engines
