Parsers for different file formats and data types.
The general use-case for any parser is to create objects out of an
InputStream (e.g. by reading a data file).
The objects are packed in a
MultipleObjectsBundle which,
in turn, is used by a DatabaseConnection-Object
to fill a Database
containing the corresponding objects.
By default (i.e., if the user does not specify any specific requests),
any KDDTask will
use the StaticArrayDatabase which,
in turn, will use a FileBasedDatabaseConnection
and a DoubleVectorLabelParser
to parse a specified data file creating
a StaticArrayDatabase
containing DoubleVector-Objects.
Thus, the standard procedure to use a data set of a real-valued vector space
is to prepare the data set in a file of the following format
(as suitable to DoubleVectorLabelParser):
As an example file following these requirements consider e.g.: exampledata.txt
