Wikification of Learning Objects Using Metadata as an Alternative Context for Disambiguation

Abstract

We present a methodology to wikify learning objects. Our proposal is focused on two processes: word sense disambiguation and relevant phrase selection. The disambiguation process involves the use of the learning object’s metadata as either additional or alternative context. This increases the probability of success when a learning object has a low quality context. The selection of relevant phrases is perf ormed by identifying the highest values of semantic relat edness between the main subject of a learning object and t he phrases. This criterion is useful for achieving the didactic objectives of the learning object.
