Abstract
Data is converted into a minimized data representation using a suffix tree by sorting data streams according to symbolic representations for building table boundary formation patterns. The converted data is fully reversible for reconstruction while retaining minimal header information. A scanning operation is performed by searching a suffix of each of the sorted data streams for identifying a data sequence that includes a first symbol representing textual data, and a second symbol representing numerical data. The suffix tree for the converted data is then built.
