document: Supporting unified interface to wrapper generator in integrated information retrieval Given the ever-increasing scale and diversity of information and applications on the Internet , improving the technology of information retrieval is an urgent research objective . Retrieved information is either semi-structured or unstructured in format and its sources are extremely heterogeneous . In consequence , the task of efficiently gathering and extracting information from documents can be both difficult and tedious . Given this variety of sources and formats , many choose to use mediator/wrapper architecture , but its use demands a fast means of generating efficient wrappers . In this paper , we present a design for an automatic eXtensible Markup Language -LRB- XML -RRB- - based framework with which to generate wrappers rapidly . Wrappers created with this framework support a unified interface for a meta-search information retrieval system based on the Internet Search Service using the Common Object Request Broker Architecture -LRB- CORBA -RRB- standard . Greatly advantaged by the compatibility of CORBA and XML , a user can quickly and easily develop information-gathering applications , such as a meta-search engine or any other information source retrieval method . The two main things our design provides are a method of wrapper generation that is fast , simple , and efficient , and a wrapper generator that is CORBA and XML-compliant and that supports a unified interface
