The dataset contains n= 64 bodies of e-mails in binary bag-of-words representation which Filannino manually collected from DBWorld mailing list. DBWorld mailing list announces conferences, jobs, books, software and grants. Filannino applied supervised learning algorithm to classify e-mails between “announces of conferences” and “everything else”. Out of 64 e-mails, 29 are about conference announcements and 35 are not.
Every e-mail is represented as a vector containing p binary values, where p is the size of the vocabulary extracted from the entire corpus with some constraints: the common words such as “the”, “is” or “which”, so-called stop words, and words that have less than 3 characters or more than 30 chracters are removed from the dataset. The entry of the vector is 1 if the corresponding word belongs to the e-mail and 0 otherwise. The number of unique words in the dataset is p=4702. The dataset is originally from the UCI Machine Learning Repository DBWorldData.
rawDBWorld is a list of 64 objects containing the original E-mails.
