• Extensively applied strategic planning, linking technology and product developments to linking technology and product developments to business goals and market opportunities in a visual frameworkbusiness goals and market opportunities in a visual framework, supporting research and capital investment decisions, and enabling communication, alignment and consensus.
• Nevertheless, many companies, especially medium and small companies, still have difficulties in implementing and sustaining roadmapping, due to a number of factors (the time, cost and effort associated with maintaining what can be a complex process).

• Another factor that hinders the adoption of the method is a lack of quality input data on markets, competitors and technology, which often relies on knowledge gathered from expert participants in workshops.

• the product manuals of Nokia mobile phones and patent documents regarding specific technologies of mobile phones were collected from internet websites. In total, 8484 product manuals were collected, covering the period 1995 Q 2004,
•• 77 77 patent documents related to the antenna technology for mobile phones filed during the same period, extracted from the US Patent and Trade Organizations (USPTO) database.&' � ë Ú ìí î � ï ðñ òó � ôõ
• The collected data were separated into two sets to develop (train) and test the proposed approach.
• Training data associated with the period 1995 Q 2002 were used to visualize past trends of products or technology
• test data from the period 2003 Q 2004 were analyzed to validate the product Q technology roadmaps produced on the basis of the training data.
