Claims that retraining GloVe / word2vec / fastText on a domain corpus improves domain terms and senses, then shows concrete steps: build a Wikipedia domain scraper, train new vectors or fine-tune pretrained ones (start fixed then unfreeze), run intrinsic checks and an extrinsic classifier benchmark. A small toy experiment (intent classification) finds pretrained and retrained vectors perform nearly the same, and the scraper plus toy app are produced and will be released on GitHub.
