摘要：In Information extraction process, document an notation is useful which nothing but adding metadata information in documents. In many domains users create and share information which contain structured amount of information which remains hidden under unstructured data. Accessing relevant information fr om these documents is always difficult. Existing system uses attribute - value annotations for searching but it required more principled users in their annotation efforts. Also in databases data quality is also critical problem. To retrieve correct data with minimum time is also taking into consideration while searching document. To overcome these problems proposed system introduces dual approach which is on CADS (Collaborative Adaptive Data Sharing Platform) apply USHER algorithm. It uses global query worklo ad to direct the annotation process. A key novelty of CADS is that it dynamically learns with time the most important data attributes from the document, and uses this knowledge to create CADS form and this information is going to be useful for querying th e database
