Display to Users
Extract the keywords of user query for further searching
Start operation for retrieved answers by evaluating their rankings and construct the output
Formulate the keywords with logical operations (e.g. AND, OR, etc)
Perform logical combination of terms to obtain answers which satisfy the logical restrictions
Search operations by comparing keywords for documents and search requests
Aim: to give abstract of the document and label it with a few keywords
Aim: to modify the query such that it can yield the largest amount of relevant results
Problems related to linguistic:
Aim: Good organization in storing can give good performance in searching.
Aim: to let users redefined the query statements for more responsive results
Does the user have to terminate the search, or has the maximum permission no. of iteration been reached?
Read the max no. of documents to be examined by users for successive iterations. Then do the searching.
Proceed with evaluation of successive iterations and print results
Modify query using relevance judgements for the first nidocuments of previous iteration
Search document collection with newly constructed modified query and produce user output
