Nexus: evidence behind every SDG link
Nexus connects EU-funded research to the Sustainable Development Goals through an interactive map and inspectable evidence. Readers can explore goals and projects, follow associations to their source passages and ask contextual AI questions.
The prototype maps 400 CORDIS projects across Horizon Europe, Horizon 2020 and FP7 to the EU Vocabularies SDG taxonomy. A local open-weight model records each project’s own activities; 186 written rubrics and code-checked quotations support the assessment process. The publication contains 915 supported associations, with uncertainty and pending assessments disclosed.
On 20 untouched projects, agreement with a blind AI reference was 97% at goal level and 79% at exact-concept level, with 43% all-goal recall. Downloadable tables and an executed notebook expose the method, results and limitations and reproduce the analysis without model calls.
