Knowledge-Supervised Learning by Co-clustering Based Approach

Traditional text learning algorithms need labeled documents to supervise the learning process, but labeling documents of a specific class is often expensive and time consuming. We observe it is convenient to use some keywords(i.e. class-descriptions) to describe class sometimes. However, short class-description usually does not contain enough information to guide classification. Fortunately, large amount of public data is easily acquired, i.e. ODP, Wikipedia and so on, which contains enormous knowledge. In this paper, we address the text classification problem with such knowledge rather than any labeled documents and propose a co-clustering based knowledge-supervised learning algorithm (CoCKSL) in information theoretic framework, which effectively applies the knowledge to classification tasks.
