Description
In this report we demonstrate how we made the multi-lingual text classifier to match research papers to the Sustainable Development Goals (SDGs) of the United Nations.
We trained the mBERT multi-language model to classify the 169 individual SDG Targets, based on the English abstracts in the corpus of 1.4 million research papers we gathered using the Aurora SDG Query model v5.
This is a follow-up project of the query based Aurora SDG classification model. The purpose of this project is to try and tackle several issues: 1. to label also research output to an SDG that is written in a non-english language, 2. to include papers that use other terms than the exact terms used in keyword searches, 3. to have a classification model that works independent from any other database specific query language.
In this report we show how we decided to use the abstracts only and the mBERT model to train the classifier. Also we show why we trained 169 individual models, instead of 1 multi-label model, including the evaluation for prediction. We will show how to prepare the data for training, and how to run the code to train the models on multiple GPU cores. Next we show how to prepare the data for prediction and how to use the code to predict English and non-English texts. And finally we evaluate the model by reviewing a sample of non-English research papers, and provide some tips to increase the reliability of the predicted outcomes.
