Title: Elevator Control Simulation System Based on Singlechip
Abstract: The Web Information Extraction and Knowledge Presentation System is proposed to extract information from data intensive web pages.It downloads dynamic web pages,based on a knowledge database,changes them to XML documents after preprocessing,finds repeated patterns from them,by using a PAT-array based Pattern Discovery Algorithm,recognizes their data display structure models,automatically based on the repeated patterns and an ontology-based keywords library,and then extracts the data and stores them in the knowledge database with the object-relational mapping technology of XML.Through these steps,web data is extracted automatically,and the knowledge database is also expanded automatically.Experiments on the traffic information auto-extraction and mixed traffic travel schemes auto-creation system showed that the system has high precision and is adaptive to web pages in different domains with different structures.
