Domain-specific Evaluation of Word Embeddings for Philosophical Text using Direct Intrinsic Evaluation

We perform a direct intrinsic evaluation of word embeddings trained on the works of a single philosopher.Six models are compared to human judgements elicited using two tasks: a synonym detection task and a coherence task.We apply a method that elicits judgements based on explicit knowledge from experts, as the linguistic intuition of non-expert participants might differ from that of the philosopher.We find that an in-domain SVD model has the best 1-nearest neighbours for target terms, while transfer learning-based Nonce2Vec performs better for low frequency target terms.
