Abstract: AbstractThis paper explores the use of a machine learning algorithm to automate the task of classifying learning materials into categories useful for instruction. A collection of documents was segmented manually into independent learning objects. A regularized linear text classifier was trained to recognize four topic categories and eleven instructional use categories using manual category labels as training data. The classifier was able to categorize text-based learning objects into topic categories with high accuracy, but initial performance for instructional use classification was poor. An enhanced classifier was able to distinguish between conceptual and procedural categories of instructional use with high accuracy.
