OSDG is an open-source tool that maps and connects activities to the UN Sustainable Development Goals (SDGs) by identifying SDG-relevant content in any text. The OSDG tool is available free of charge at OSDG.ai.

The tool supports the following types of input:

1. Text fragments
2. PDF files.

The system uses state-of-the-art neural machine translation models to translate the input into English. OSDG currently supports 15 languages: English, Arabic, Danish, Dutch, Finnish, French, German, Italian, Korean, Polish, Portuguese, Russian, Spanish, Swedish, and Turkish.

For each query, we return a detailed breakdown of all SDGs found in the text, entitled the OSDG Wheel. You can learn more about it here.

Methodology

OSDG 2.0 works in two stages. The first stage uses machine learning (ML) models, trained on the data collected via the OSDG Community Platform (CP). You can access this data through the osdg-data repository. These models carry out the initial screening of texts and suggest the preliminary SDG labels. In the second stage, OSDG uses its ontology/keyword map to verify the initial labels. To assign a specific SDG label, both the ML and ontology approaches must be in agreement.

For a more detailed description of the methodology, please refer to our paper on ArXiv:

⚠️ Repository files

OSDG 2.0 is not available on the repository due to the use of ML and ontology approaches and machine translation. To access the latest version of the tool, visit the OSDG website.

OSDG API is available free of charge for research teams, please contact us for more information.

🔴 Please note: At the moment, the files in this repository refer to a legacy version of the tool, OSDG 1.0. You can use them to set up a legacy OSDG application via Docker. However, the results obtained may not correspond to the most recent version of the tool, OSDG 2.0. For the highest quality results, please refer to the online version of the tool, or consult us for API access.
