Thomson Scientific Predicts Nobel Laureates


PHILADELPHIA, and LONDON, Sept. 5 /PRNewswire-FirstCall/ -- 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.

The 2006 Thomson Scientific Laureates in four Nobel Prize categories are
as follows:
