A Concept Lattice-Based Kernel for SVM Text Classification
[chapter]
2009
Lecture Notes in Computer Science
Preserved Fulltext
We describe a method to perform SVM text classification with concept lattice-based kernel, which consists of text pre-processing, feature selection, lattice construction, computation of pairwise term similarity ...
Such a kernel is based on the notion of conceptual proximity between pairs of terms, as encoded in the document lattice. ...
Following this idea, we have implemented a full SVM text classification system with concept lattice-based kernel. ...

For the TREC 2007 conference, the CRM114 team considered three nonBayesian methods of spam filtration in the CRM114 framework -an SVM based on the "hyperspace" feature==document paradigm, a bitentropy ...
The results show that the SVM has a spamfiltering accuracy of about a factor of two to three better accuracy than the OSB system, that substring compression is somewhat more accurate than OSB, and that ...
This classifier is rather unique in that not only doesn't it have any concept of a text string; it doesn't even have any concept of a byte. ...
