As described in Section 4.3.4, the Sequential Model is
supported by a slight modification to the example format, which allows
examples to specify which target nodes they should be presented to. After the
last active feature in the example but before the colon, insert a semicolon
followed by a list of target IDs. Examples with this structure added to it
will only be presented to the target nodes whose IDs are listed after the
semicolon. Examples without this structure will be presented to all target
nodes. IDs found after the colon are not assertions stating that ID is active
in the example, and they cannot have strengths attached to them. For
instance, in a learning scenario with target IDs 3, 5, 10, and 16, the
following example will only be presented to target nodes 5 and 10:
5, 9, 12, 25(0.32), 45(0.87), 103, 104; 5, 10:
SNoW is always capable of reading examples of this form. No extra command line parameter need be set; SNoW will automatically handle examples of this form in the manner described above. Note that omitting all target IDs between the semi-colon and colon at the end of an example is equivalent to also omitting the semi-colon.
