IN THE NEWS: Consumers suspicious of sponsored links
According to recent reports, businesses spent an estimated $8 billion to sell their products and services via sponsored links in 2004, despite little evidence that such advertising successfully directs traffic to Web sites. More likely to hook consumers are the organic results or those results returned automatically by the algorithmic operations of the search engine, Jansen said. The Penn State IST researcher presented that finding June 5 at the Sixth ACM Conference on E-commerce in Vancouver, Canada. Details of the study are in a paper, "Examining Searching Perceptions of and Interactions with Sponsored Results," co-authored with Marc Resnick, associate professor of industrial and systems engineering, Florida International University.

IN THE NEWS: WEB SEARCHING MORE SUCCESSFUL WITH PERSONALIZED ASSISTANCE SYSTEM
A Penn State researcher has developed software that improves Web searching with a personalized system that offers automated assistance for structuring and refining queries, evaluating search results and finding more relevant information. "Research shows 50 percent of all Web results retrieved are not relevant, pointing to a need for improved searching techniques," said Jim Jansen, assistant professor of information sciences and technology. "This technology enabled a 20-percent performance increase." The technology, designed to be integrated with a browser, monitors what searchers are looking for based on user-system interactions and then interjects help in finding needed information. Other approaches to personalizing searches rely upon "explicit feedback" where the system interrupts searchers as they hunt for information. Research has shown that only 1 percent to 2 percent of users are likely to use such systems because of the extra effort involved, Jansen said.

IN THE NEWS: COMPANY WEB SITES NEED REDESIGN TO LURE JOB-SEARCHERS
Companies wanting to use the Internet to recruit new employees should spotlight the geographic location of positions on their Web sites and include terms used by searchers, rather than site designers or human resource professionals, according to Penn State researchers. "Users′ primary interest when looking for jobs is location, but company Web sites typically don′t highlight geographical information," said Jim Jansen, assistant professor of information sciences and technology. "Location ranks above industry, position, particular companies and even job skills." Jansen and co-authors Karen J. Jansen, assistant professor of management in The Penn State Smeal College of Business; and Amanda Spink, University of Pittsburgh, drew their conclusions by analyzing 7,000 job-related queries submitted to Excite on Sept. 16, 1997; Dec. 1, 1999; and April 30, 2001. The researchers also learned that online job searches yield a higher percentage of non-relevant returns than general Web searches -- 60 percent for job searches compared to 50 percent for general searches, Jansen said.

IN THE NEWS: Web Search: Public Searching of the Web by Amanda Spink and Bernard J. Jansen is one of the first manuscripts that addresses the human - system interaction of Web searching in a thorough and complete manner. The authors provide an examination of Web searching from multiple levels of analysis, from theoretical overview to detailed study of term usage, and integrate these different levels of analysis into a coherent picture of how people locate information on the Web using search engines. This research is directly relevant to those interested in providing information or services on the Web, along with those who research and study the Web as an information resource. Graduate students, academic and corporate researchers, search engine designers, information architects, and search engine optimizers will find the book of particular benefit.

IN THE NEWS: Searching experts who tout the benefits of using advanced query markers have it wrong: Web searches with "and," "or," "must appear" and "phrase" fare no better than simple, dressed-down submissions, according to a Penn State researcher. "Our research shows that query operators, commonly thought to narrow searches, don′t return more relevant results and don′t reduce the number of non-relevant results," said Bernard J. Jansen, assistant professor of information sciences and technology, who co-authored an article on the topic with a colleague at the University of South Carolina for the October issue of ACM Transactions on Information Systems. MSN reports 7 times more results than AOL or Google. Google does a little better on relevance. No difference among the three on ranking. Read the Penn State Press Release.
