ABSTRACT:
In some embodiments, a layout-based electronic communication classification (e.g. spam filtering) method includes generating a layout vector characterizing a layout of a message, assigning the message to a selected cluster according to a hyperspace distance between the layout vector and a central vector of the selected cluster, and classifying the message (e.g. labeling as spam or non-spam) according to the selected cluster. The layout vector is a message representation characterizing a set of relative positions of metaword substructures of the message, as well as metaword substructure counts. Examples of metaword substructures include MIME parts and text lines. For example, a layout vector may have a first component having scalar axes defined by numerical layout feature counts (e.g. numbers of lines, blank lines, links, email addresses), and a second vector component including a line-structure list and a formatting part (e.g. MIME part) list.
