Work context

The PROMTECH project


European project to identify and assess
promising emerging technical fields
Consortium:
Austrian Research Centers GmbH – ARC systems research, Vienna
Fraunhofer Institut für Systemtechnik und Innovationsforschung, Karlsruhe
INstitut de l‘Information Scientifique et Technique, CNRS, Nancy

Operational choices:
Search for articles in Engineering and Life Sciences with links to Physics
Use of PASCAL database for its fine classification for individual papers
(i.e. a paper may have several codes or domains)
300+ fields
Identification of fields with 4 growth indexes
45 fields
Final selection by experts
10 fields

Home technology terms




From the 45 fields (period 2005-2009), we extract the
keywords,
Based on its relative frequency, each keyword is assigned
a technological field: its “home technology”,
Each technology is characterized by a set of keywords
we call “home technology terms”,
Each technology is also indexed by keywords from other
home technologies:
interrelationships
trade balance

An artificial construction with artifacts

Case study: optoelectronics


Definition: study and application of electronic devices
that source, detect and control light.
Negative trade balance:
export: 487 HT terms
import: 1883 HT terms
Net importer from all
the other fields


used to find the different intersections between Physics and
Engineering or Life Sciences
Neurodoc: clustering tool using an axial K-means algorithm
all records from other fields with at least one HT term from
Optoelectronics

Conclusion





We were looking for innovation at the intersection of
Physics and Engineering or Life Sciences,
Using the well-defined domain classification scheme of
the PASCAL database,
We assigned terms to technologies in a pragmatic way
“home technology terms”,
To analyze the interrelationships and the trade balance
between fields.
How useful is it? Still not sure, but we are working on it.
