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 = {Seventy percent of smallholder farmers in Africa depend on rainfed farming systems, making them vulnerable to climate variability and extremes. Climate information services (CIS) adoption by smallholder farmers in Africa presents a promising solution for adaptation to climate variability. This paper unravels the complexities around climate services for smallholder farmers and explores opportunities to tailor CIS for the resources of smallholder farmers. We use a systematic literature review approach to assess how the human, social, physical/technical, natural and financial capitals may affect awareness, access and use of CIS by smallholder farmers. The study is based on 33 papers from Africa. Majority of the studies gave emphasis on education, information communication and technology literacy levels and advisory services as influencing CIS access, use and uptake. The results highlight that better resourced smallholder farmers have higher access and are more likely to adopt CIS. The human capital emerged as an important component of CIS adoption as it directly determines how the farmer makes decisions on the farm. The natural capital determines the specific preference for CIS when the financial and economic capitals enable farmers acting according to the information received. The social capital provides a basis for farmers to benefit from compounded resources. Thus, the livelihood resource capitals of the target farmers must be considered in CIS information production and dissemination to improve the chances of CIS adoption by vulnerable groups that is illiterate, women, elderly, farmers in agroecological zones prone to climate extremes and poorly resourced farmers.},

abstract = {The confrontations of stakeholder visions about agriculture and food production has become a focal point in the public sphere, coinciding with a diversification of agrifood models. This study analyzes the debates stemming from the coexistence of these models, particularly during the initial term of neoliberal-centrist Emmanuel Macron’s presidency in France.
Employing collective monitoring from 2017 to 2021, a corpus of 958 online news and blog articles was compiled. Using a computational analysis, we reveal the framings and controversies emerging from this media discourse. The macro-structuring of discourse on model coexistence revolves around scientific, economic and political framings. Coexistence is a complex of debates based on specific frames associated with specific arenas and actor configurations: growth of organic agriculture, transformations of agrifood systems, sciences of production and impacts, livestock and meat diet controversies, agroecological innovations, CAP reform criticism, discourse of peasant agriculture and State-Profession co-gestion. Employing global sentiment analysis and focusing on salient controversies, namely EGAlim law, pesticide regulations, and agribashing, we show the shift from conciliation to a hardening of debates. Finally, we discuss the causes and consequences of this trend. The political will to support the transition of agriculture remains influenced by the co-gestion system, an inherited configuration of decision-makers instrumental in the agricultural modernization. As a consequence, significant agricultural challenges, particularly highlighted in the scientific macro-frame, persist unresolved. This lock-in of the agrifood system is based on defensive strategies that challenge the democratic debate about food and agricultural practices.},

abstract = {Purpose
The global prevalence of social media and its potential to cause polarization are highly debated and impactful. The previous literature often assumes that the ideological bias of any media outlet remains static and exogenous to the polarization process. By studying polarization as a whole from an ecosystem approach, the authors aim to identify policies and strategies that can help mitigate the adverse effects of polarization and promote healthier online discourse.
Design/methodology/approach
To investigate online polarization, the authors perform a systematic review and analysis of approximately 400 research articles to explore the connection between cognitive bias and polarization, examining both causal and correlational evidence. The authors extensively evaluate and integrate existing research related to the correlation between online polarization and crucial factors such as public engagement, selective exposure and political democracy. From doing so, the authors then develop a PolarSphere ecosystem that captures and illustrates the process of online polarization formation.
Findings
The authors' review uncovers a wide range of associations, including ideological cognition, bias, public participation, misinformation and miscommunication, political democracy, echo chambers and selective exposure, heterogeneity and trust. Although the impact of bias on social media polarization depends on specific environments and internal/external conditions, certain variables exhibit strong associations across multiple contexts. The authors use these observations as a basis from which to construct PolarSphere, an ecosystem of bias-based polarization on social media, to theorize the process of polarization formation.
Originality/value
Based on the PolarSphere ecosystem, the authors argue that it is crucial for governments and civil societies to maintain vigilance and invest in further research to gain a deep comprehension of how cognitive bias affects online polarization, which could lead to ways to eliminate polarization.},

abstract = {Soil health is vital for many ecosystem services. The Horizon Europe (HE) Mission “A Soil Deal for Europe” aims to accelerate the transition to sustainable soil and land management and healthy soils through an am-bitious transdisciplinary research and innovation (R&I) programme, largely based on actor engagement, Liv-ing Labs and Lighthouses. The H2020 Soil Mission Support (SMS) project supported the implementation of the HE Mission, and aimed to improve the coordination of R&I on sustainable soil and land management. Through a co-creation process together with actors, SMS collated available knowledge, actors R&I needs and identified R&I gaps that need to be addressed for successful transition towards sustainable soil and land management. The first step was to identify existing R&I knowledge through a keyword-based analysis of scientific literature published and peer reviewed, related to sustainable soil and land management. The literature analysis ad-dressed the full range of societal challenges, soil health objectives, land use types and knowledge domains necessary to capture the socio-ecological complexity of soil health. Covering some 15,700 scientific articles, this literature analysis represents the current peer reviewed knowledge stock on sustainable soil and land management. A textual analysis using the digital platform CorTexT was undertaken to explore the identified literature and submitted to project consortium internal experts, who analysed and processed the collected information of their respective area of expertise (Annex III). The literature analysis revealed that the societal challenges “reduce soil degradation” and “improve disaster control” have been studied extensively. Con-versely, the societal challenges “mitigate land take” and “increase biodiversity” and the knowledge domains “science-based policy support” and “awareness, training & education” are less discussed. Factsheets present-ing the results of the literature analysis per societal challenge were developed and can be found in Annex VIII. Note that as the key-word based literature search was limited to Scopus-indexed scientific journals, other publishing formats such as conference papers, books, book chapters, non-digitalized articles, grey literature, reports, patents, etc., may be underrepresented or not included in the used data base. The exclusive use of Scopus-indexed scientific articles provided quality insurance of the material through the publication peer-review system. Nonetheless, important documents and knowledge have been incorporated by the consor-tium experts when analysing the collected literature. The second step was to consult actors through online workshops and surveys in order to gain a practice-oriented ‘real-life’ picture of current knowledge and R&I needs for swift implementation of sustainable soil and land management. This step was seen as complementary of the published and peer-reviewed literature. Finally, after exploring our stocktaking of R&I from existing knowledge evidenced by literature review and the actor’s knowledge needs identified from actor consultations, we identified R&I gaps. The main knowledge gaps across all Mission Objectives were of socio-economic nature: drivers and causes of land degradation, knowledge management, governance and policies for inciting improved management, and interaction with other sectors are not sufficiently understood. Second, the HE Missions’ focus on improving soil literacy was supported by the literature analysis and by the actor consultation, which both revealed knowledge gaps re-lated to education and capacity building in all land use types and domains affecting soil health: production, consumption, trade, policy and governance. Thirdly, there is a gap in the long-term implementation of a new mode of knowledge co-design, where researchers and practitioners together develop solutions for sustaina-ble soil and land management in a real-world context. The HE Missions’ focus on Living Labs and Lighthouses has the potential to close this gap. Finally, there is a need to define several concepts (e.g. soil health, soil degradation, footprint). Such definitions should be shared and will be a basis to identify relevant indicators and respective thresholds, and to develop guidelines to support monitoring programmes in order to translate knowledge into evidence for decision making. The outcome of the deliverable is a list of validated R&I gaps across all Mission Objectives which will feed into the SMS roadmap and the HE Mission. },
