Abstract: WebDoc is an automated classification system that assigns Web documents to appropriate Library of Congress subject headings based upon the text in the documents. We have used different classification methods in different versions of WebDoc. One classification method is a statistical approach that counts the number of occurrences of a given noun phrase in documents assigned to a particular subject heading as the basis for determining the weights to be assigned to the candidate indexes. The second classification method uses a naïve Bayes approach. In this case, we experimented with the use of smoothing to dampen the effect of having a large number of 0s in our feature vectors. The third classification method is a k-nearest neighbors approach. With this approach, we tested two different ways of determining the similarity of feature vectors. In this paper, we report the performance of each of the versions of WebDoc in terms of recall, precision, and F-measures.
