PHILADELPHIA, and LONDON, Sep. 5, 2006 (Canada NewsWire via COMTEX News Network) -- Twenty-seven `Thomson Scientific Laureates' Recognized for Their

Contributions to the Advancement of Science

Thomson Scientific, part of The Thomson Corporation (NYSE: TOC; TSX: TOC) and leading provider of information solutions to the worldwide research and business communities, today announced its 2006 Thomson Scientific Laureates - researchers likely to contend for Nobel honors - in anticipation of this year's Nobel Prize winners to be announced in October.

Each year, data from ISI Web of Knowledge(SM), a Thomson Scientific research solution, is used to quantitatively determine the most influential researchers in the Nobel categories of chemistry, economics, physiology or medicine, and physics. Because of the total citations to their works, these high-impact researchers are named Thomson Scientific Laureates and predicted to be Nobel Prize winners, either this year or in the near future. Of the 27 Thomson Scientific Laureates named since 2002, four have gone on to win Nobel honors - an accurate-prediction average of better than one in seven.

"Citations are an acknowledgement of intellectual debt - a direct demonstration of influence in a given subject area," said Henry Small, chief scientist at Thomson Scientific. "Over the past 30 years, our studies have demonstrated a strong relationship between journal article citations and peer esteem. Researchers who have accumulated such credits from their peers are also often nominated for prizes and other honors, such as the Nobel Prize."

Thomson Scientific is the only organization to use quantitative data to make annual predictions of Nobel Prize winners. The Thomson Scientific Laureates typically rank among the top one-tenth of one percent (0.1%) of researchers in their fields, based on citations of their published papers over the last two decades.

To select the 2006 Thomson Scientific Laureates, total citation counts and number of high-impact papers in the Nobel science fields were examined. These data were applied to categories within those scientific fields considered worthy of special recognition by the Nobel Committee: physics, chemistry, physiology or medicine, and economics. Based on these criteria, possible winners - leaders within a particularly noteworthy area of study within each field - were selected.
