Abstract: Sequence is a familiar form of data. Knowledge discovery in data sequence is an important part of KDD. Manufacture process files consist of process steps which are organized by the machining order. The process cell which consist of Muti-line process text is the embodiment of process knowledge. How to present standard process is studied and a definition of process cell is given. Which is put forward that the logical course model to mine standard process cell from manufacture process sequence. According to the muti-parttern feature of process text, a new algorithm is used to steal with the process data. It is available for mining standard process cell.
