This second part focuses on the problem of visualizing what learners have and have not seen, what new vocabulary they have just encountered, and what new and future vocabulary is above or below some threshold separating common from uncommon words. The goal here is not to provide a finished design but to present a draft that can be developed further. The technology employed is relatively simple — the visualizations are implemented as Support Vector Graphics (SVG) objects. The next version will probably be in some dialect of Javascript but the figures below demonstrate one model by which to convey the more granular view of vocabulary. Continue reading →

This paper is designed to be the first of two that explore the degree to which learners can track how much of the vocabulary as a whole in a target corpus they have encountered and to see the frequency in the rest of the corpus of each newly encountered vocabulary item. We focus here upon the Ancient Greek Iliad and the Odyssey, a corpus of just over 200,000 running words. Homeric Epic provides a useful starting point because a growing cluster of openly-licensed, digital resources for this corpus are available, including links from each form in the epic to a dictionary entry, the starting point for vocabulary analysis.
