This directory contains the Ling-Spam corpus, as described in the paper:

I. Androutsopoulos, J. Koutsias, K.V. Chandrinos, George Paliouras, and C.D. Spyropoulos, "An Evaluation of Naive Bayesian Anti-Spam Filtering". In Potamias, G., Moustakis, V. and van Someren, M. (Eds.), Proceedings of the Workshop on Machine Learning in the New Information Age, 11th European Conference on Machine Learning (ECML 2000), Barcelona, Spain, pp. 9-17, 2000.

There are four subdirectories, corresponding to four versions of the corpus:

bare: Lemmatiser disabled, stop-list disabled. lemm: Lemmatiser enabled, stop-list disabled. lemm_stop: Lemmatiser enabled, stop-list enabled. stop: Lemmatiser disabled, stop-list enabled.

Each one of these 4 directories contains 10 subdirectories (part1, ..., part10). These correspond to the 10 partitions of the corpus that were used in the 10-fold experiments. In each repetition, one part was reserved for testing and the other 9 were used for training.

Each one of the 10 subdirectories contains both spam and legitimate messages, one message in each file. Files whose names have the form spmsg*.txt are spam messages. All other files are legitimate messages.

By obtaining a copy of this corpus you agree to acknowledge the use and origin of the corpus in any published work of yours that makes use of the corpus, and to notify the person below about this work.
