Cortext platform
At Cortext, our goal is to empower researchers in the social sciences and humanities by promoting advanced qualitative-quantitative mixed methods. Our primary focus is on studies about the dynamics of science, technology and innovation, and about the roles of knowledge and expertise in societies.
We understand the move towards digital humanities and computational methods not as addressing a technological gap for the social sciences, but rather as entailing entirely new assemblages between its disciplines and those of modern statistics and computer sciences. We work to tackle ever more complex research problems and deal with the profusion of new and diverse sources of information without losing sight of the situatedness and reflexivity required of studies of human societies.
Cortext is hosted by the LISIS research unit at Gustave Eiffel University, and was launched by French institutes IFRIS and INRAE, receiving their continued support.
Cortext Manager
Cortext Manager is our current main attraction, a publicly available web service providing data analysis methods curated and developed by our team of researchers and engineers.
You upload a textual corpus in order to analyse its discourse, names, categories, citations, places, dates etc, with methods for science/controversy/issue mapping, distant reading, document clustering, geo-spatial and network visualizations, and more.
You can jump straight to Cortext Manager and create an account, but we strongly suggest taking a look at the Documentation and Tutorials as you start your journey.

abstract = {Digitale metoders centrale postulat er, at vi kan genanvende nettets medier til at sige noget om samfundet i øvrigt. Det gælder ikke mindst indenfor kontroverskortlægningen,hvor digitale medier er blevet væsentlige skuepladser for diskussioner om ny viden og teknologi. Begrebet genanvendelse synes at indebære, at en eksisterende metodisk og analytisk tradition finder nye måder at bruge nogle redskaber på. Vi kan således have en tendens til at spørge, hvordan kontroverskortlægningen har fundet nye anvendelser for værktøjer til eksempelvis mønstergenkendelse eller automatiseret tekstanalyse. I denne artikel argumenterer jeg for, at vi bør stille spørgsmålet om genanvendelse anderledes. Efter 15 år i tæt parløb med nettets indfødte medier og metoder kan vi konstatere, at det også er kontroverskortlægningen selv, der har forandret sig; at det i nogen grad også er den metodiske og analytiske tradition, der er blevet genanvendt til nye formål og i sine nye redskabers billede.},

abstract = {We mapped submarine canyon research using a scientometric approach to define and characterize its scientific landscape based on a comprehensive bibliographic dataset. The abundance of studies covering structural and functional aspects of submarine canyons allowed us to identify the existing knowledge clusters, historical trends, and emergent topics in canyon research. Our analysis documented a network of knowledge clusters of which four were particularly relevant: a strong cluster on “Geology & Geophysics”, well established since the beginnings of canyon research; a cluster on “Biology & Ecology” that gained strength primarily over the past two to three decades; a cluster on “Oceanographic Processes” which occupied a central position in the network and connected strongly to almost all the other clusters and especially to the fourth main cluster on “Modelling”. A smaller, but also well connected, cluster on “Biogeochemistry” related closely to “Biology & Ecology”, and three other small clusters (“Sedimentology”, “Sediments & Tidal Currents”, “Canyon Sampling”) bridged the main clusters. Finally, we identified three small, but specific satellite clusters (“Oil & Gas”, “Chemosynthetic Communities”, “Molecular & Symbionts”). The high-level structure of the knowledge network reflects a latent interdisciplinarity in canyon research. However, the evolution of the research lines over the past nine decades suggests that this pattern arose mostly in the new millennium. Emergent research topics in the last decade also reveal a concern regarding anthropogenic impacts and climate-driven processes. Our results also show a well implemented and international collaboration network, although research efforts have been mainly directed towards only a few canyon systems. A geographical and thematic bias also characterizes canyon research, with specific topics addressed preferentially in particular canyons by different leading research institutions. This spatial and thematic bias, together with the paucity of truly inter-disciplinary studies, may be the most important limitation to integrated knowledge and development in canyon research and hinders a global, more comprehensive understanding of canyon patterns and processes. The scientific landscape mapping and the complementary results are made available as an open and interactive platform that canyon stakeholders can use as a tool to identify knowledge gaps, to find key players in the global collaboration network and to facilitate planning of future research in submarine canyons.},

Textual Analysis of Published Research Articles on the Environmental Impacts of Land-Use Change Journal Article

abstract = {Regardless of the scale considered, land use is determined by a variety of factors relating to both local soil and climatic conditions and socioeconomic considerations (population growth, food and energy requirements, public policies, etc.). Changes in land use resulting from shifts in these factors over time will have environmental consequences. We conducted a review of the scientific literature to identify the degree to which environmental assessments take direct and indirect land-use change into account. A textual analysis was completed on a collection of 5730 scientific articles, published between 1975 and 2015 and listed in the WoS™ database, addressing the relationship between reorganizations of agricultural and forestry systems, or spatial planning, direct and indirect land-use change resulting from these reorganizations; and environmental impacts. By identifying the most frequently used words or groups of words within this corpus (focusing on the title, abstract, and keywords fields), the textual analysis platform CorTexT Manager (Platform developed by IFRIS (the Institute for Research and Innovation in Society, based in the Paris region) assembles diagrams, or “maps,” of occurrence and co-occurrence for these terms, which can then be used to identify the principal themes addressed in the corpus based on clusters of proximate keywords. Eight clusters were so identified: two focused on climate change and greenhouse gas fluxes in terrestrial ecosystems (thus corresponding both to an aspect of the biophysical context and an environmental impact linked to a reorganization); one associated a reorganization (biofuel production) with a dominant environmental impact (the effects of greenhouse gas emissions); three were centered on keywords related to other types of reorganizations (urbanization, grassland management, forestry management); and two focused on environmental impacts on biodiversity and water resources. The five “thematic identifiers” showing the highest number of occurrences were greenhouse gas emission, land-use policy, biofuel, farm system, and pasture land, suggesting that the theme “GHG impacts of biofuel production” is the most prevalent. A more detailed textual analysis of articles in the cluster relating to non-food biomass production (1785 articles) was also conducted, and confirmed the growing importance, notably since 2005–2006, of research linking the bioenergy production, land-use change, and climate impacts from greenhouse gas emissions. Reorganizations toward non-food biomass production also help explain the presence of degraded lands among the most frequently occurring terms in the corpus. Life-cycle analysis is the most important assessment methodology used to evaluate the environmental impacts of bioenergy production.},

abstract = {The environmental impact of land-use change for biomass production is controversial, and it is crucial to provide stakeholders with a reliable description of the existing evidence on this topic. In this paper, we use an emerging research synthesis method called “evidence mapping” to summarize the main characteristics of 241 studies in a graphical user-friendly format. Results showed that most of the reviewed studies were located in Northern and Southern Americas, especially in USA and Brazil. A majority of studies focused on 1G and 2G biofuel, and on electricity production. The impacts on greenhouse gas emission, soil carbon content, soil erosion, water consumption, and water eutrophication were frequently assessed in the selected group of studies. The evidence maps produced in this paper revealed that only few studies were conducted to analyse the environmental impact of Land use change for methane production, for wood production, and for the chemical industry. Only few studies assessed the impact on biodiversity, on air quality, on human health, and on waste induced by land-use changes for biomass production. Our results thus highlight major gaps of knowledge and future research needs on the land-use-mediated implications of the bioeconomy.},
