Opinion retrieval is a retrieval task in which not only the relevance of a document to the topic is important but also the amount of opinion expressed in the document about the topic. Like the Frakes and Baeza-Yates book that came before it [1], this book offers algorithms to implement a retrieval system.

Moreover, exercises, a list of additional readings, and a bibliography appear at the end of each chapter, and contribute much to the overall desirability of the Dictionary structures for a document retrieval system book.

Document pre-processing is the process of incorporating a new document into an information retrieval system. The goal is to Represent the document efficiently in terms of both space (for storing the document) and time (for processing retrieval requests) requirements.

Maintain good retrieval performance (precision and recall). Information retrieval is the process through which a computer system can respond to a user's query for text-based information on a specific topic. IR was one of the first and remains one of the most important problems in the domain of natural language processing (NLP).

An information retrieval system includes a store of units of information, specific subjects. The assembly of specific subjects so stored may incorporate all the relations mentioned above.

Information retrieval is the activity of obtaining information resources relevant to an information need from a collection of information resources. An information retrieval process begins when a user enters a query into the system.

The retrieval/scoring algorithm is subject to heuristics/ constraints, and it varies from one IR model to another. For example, a term frequency constraint specifies that a document with more occurrences of a query term should be scored higher than a document with fewer occurrences of the query term.

Numerous workers in the field have pointed out the relationship between formal logic and the requirements of an information retrieval system (5–7, 9, 10).Most of the work has been on theoretical grounds with considerable disagreement regarding symbols to be used and the extent to which the problems of information retrieval are actually served by the concepts of formal logic.

Information retrieval (IR) is the area of study concerned with searching for documents, for information within documents, and for metadata about documents, as well as that of searching structured storage, relational databases, and the World Wide is overlap in the usage of the terms data retrieval, document retrieval, information retrieval, and text retrieval, but each.

Finally, the retrieval function could be made more efficient based on new algorithms either found or developed. Although positive results are always important, emphasis at this time is the proposed approach to document representation and retrieval.
