Survey on Facilitating Document Annotation using Content and Querying Value

Annotation is a process of adding the information into the Document which are useful in effective information retrieval. Annotation can be apply to several fields like image, videos, documents, etc. It helps to understand and retrieve the documents very easily. For doing annotation, firstly important attributes have to be identified. Making annotations on documents is a difficult work because people have to read the documents fully to that think which Sentences have to be annotated. In this paper, two techniques of annotations is discussed and description about proposed system is given. In that paper, CADS System is used to generate the structured attribute by identifying the documents which contain the information of interest and that information in future useful for querying the database. Here, we use LableMe which is an annotation tool for image annotation. The large contribution of that paper, here, we provide a facility of annotating the images that may present in the /820 documents which helps user to retrieve data that is useful and faster than existing system. Techniques used in that paper will give the best results compared to that methods which only relay on the content of the document or only on the query workload.
