consists of a series of concrete operations (Losee 1972 ), and also seems consistent with Kuhn's notion of normal science as puzzle solving ( 1970 ), as well as Latour's inscription devices in the laboratory ( 1979 , Chap. 2).

The interweaving of three different sorts of software based on different algorithms (co-world analysis and downward hierarchical
classification) and applied on a file (in the field of risk assessment through the introduction of transgenic plants) extracted
from the CAB (Commonwealth Agricultural Bureau) data base, has enable us to provide three types of results: Leximappe provides
a synthetic image from clusters of key-words. The main themes were identified. Alceste improves a corpus' characterization
and allows a logical reading of it, thanks to the creation of categories, along with their mutual dependencies, the peculiar,
meaning of each and their division in time. Moreover, Alceste allows us to perceive the contexts of the contents previously
identified under Leximappe. Sampler allows us to go into the details of the terms association in graphical form and detail
the specific orientations of the corpus, especially with the inscription of weak signals. Finally, this software, applied
from the categories drawn from Alceste, offers for each category a meaningful graphic representation. We can argue that the
different ways of measuring and presenting results are complementary since they highlight different aspects of risk assessment
carried by different actors, as it is underlined in social science studies of public controversy. Moreover we can follow these
actors through the categories and clusters (socioeconomic, scientific and risk assessment linked to regulation and policy)
which are more and more differenciated in time. This methodology allows the study of emerging processes in the social construction
of issues within controversies.
