SGWrap System o SGWrap mainly consists of three parts O SGWrap Runtime(Runtime, for short), which provides service to access our algorithms for web page content extraction It acts as the underlying functional layer of whole system and if you want to reuse or integrate your wrapper you also need reuse or ntegrate the runtime itself O SGWrap Compiler(Compiler, for short), which can compile SGWrap rules into wrapper in both source code form and bytecode form It does something like translation and the generated source code is human readable and can be modify to fulfill you special need. The bytecode is just compiled with help of Javas compiler javac. exe O Visual SGWrap, a visual tool to generate rules. It just need you interact with it by simple selecting and clicking operation, then it can calculate out the proper rules

It can semi-automatically generate programs called wrapper built from extraction rules through user interactions. A wrapper for a set of web pages is a program used to extract contents from the pages and output strutured data for further processing. A wrapper, materialized as a java program by sgWrap system, for some certain pages can be easily generated using the visual sgWrap tool of the system and can be reused or integrated in many information systems
