We hope you found the information helpful. It is ambiguous and doesnt have a defined structure. As opposed to a conventional database management system, an information retrieval system is designed to deal with unstructured data. The data retrieval system is well structured. The latter is used to determine the information needed to be able to provide the right match when the Boolean expression is found to be true. Probabilistic Models The probabilistic model is rather simple and takes the probability ranking to display results.
