INTERNET & WEB SERVICES-2
Dear Students, you have noticed that the idea of ‘relevance’ has slipped into the discussion. The purpose of an automatic retrieval strategy is to retrieve all the relevant documents at the same time retrieving as few of the none-relevant as possible. When the characterization of a document is worked out, it should be such that when the document it represents is relevant to a query, it will enable the document to be retrieved in response to that query. Human indexers have traditionally characterized documents in this way when assigning index terms to documents. The indexer attempts to anticipate the kind of index terms a user would employ to retrieve each document whose content he is about to describe.
