RWTH ForschungPraktikum CSSH
The goal of our project is to produce word embeddings from a Wikipedia dataset, and to apply the POLAR framework to different categories of words (e.g. Countries, Food, Music, etc.) in order to analyse the semantic associations behind concepts on Wikipedia.The POLAR framework is a method that enables interpretability for pre-trained word embeddings by making use of semantic differentials.The semantics of a word can be measured using semantic differentials by analysing its position on a scale between a word and its antonym.In this paper we generate pairs of antonyms, using different methods, which can be used as the semantic differentials for the POLAR framework.To evaluate the interpretability of the pairs of antonyms generated, we performed a survey to collect the opinions of people from different countries towards the selected polar opposites.We compare the results with the conclusion from the POLAR framework and evaluate the quality of the semantic differentials produced.
