This book constitutes the joint refereed proceedings of the three workshops held in conjunction with the 6th International Conference on Web Information Systems Engineering, WISE 2005, in New York, NY, USA, in November 2005. A total of 47 papers were submitted to the three workshops, and 28 revised full papers were carefully selected for presentation. The workshop on Web Information Systems Quality (WISQ 2005) - discussing and disseminating research on the quality of WIS and Web services from a holistic point of view - included 7 papers out of 12 submissions. The workshop on Web-based Learning (WBL 2005) accounted for 10 papers from 14 papers submitted - organized in topical sections on tools, models, and innovative applications. The workshop on Scalable Semantic Web Knowledge Base Systems (SSWS 2005) included 11 presentations selected from 21 submissions. Topics addressed are scalable repository and reasoning services, practical Semantic Web applications, query handling and optimization techniques.

Welcome to the tenth anniversary of the International Conference on Web Information Systems Engineering, WISE 2009. This year the WISE conference continued the tradition that has evolved from the inaugural conference held in 2000 in Hong Kong and since then has made its journey around the world: 2001 Kyoto (Japan), 2002 Singapore, 2003 Rome (Italy), 2004 Brisbane (Australia), 2005 New York (USA), 2006 Wuhan (China), 2007 Nancy (France), and 2008 Auckland (New Zealand). This year we were happy to hold the event in Poznan, a city of 600,000 inhabitants in western Poland. Poznan is the capital of the most affluent province of the country – Wielkopolska – which means “Greater Poland”. For more than 1,000 years, Poznan’s geographical location has predestined the city to be a significant scientific, cultural and economic center with more than just regional influence. The city is situated on the strategic cross-roads from Paris and Berlin in the west, to Warsaw and Moscow in the east, and from Scandinavia through the Baltic Sea in the north to the Balkans in the south. Poznan is a great research and university center with a dynamic potential. In all, 140,000 students are enrolled in 26 state-run and private institutions of higher education here, among which the Poznan University of Economics with its 12,000 students is one of the biggest. The WISE 2009 Conference provided a forum for engineers and scientists to present their latest findings in Web-related technologies and solutions.
