    This paper reports on a novel technique for literature indexing and searching in a mechanized library system. The notion of relevance is taken as the key concept in the theory of information retrieval and a comparative concept of relevance is explicated in terms of the theory of probability. The resulting technique called “Probabilistic Indexing,” allows a computing machine, given a. Document indexing is a powerful technique to aid subsequent retrieval of documents from repositories that contain thousands of documents. Documents might be indexed by their full-text content or by metadata attached to the document such as a unique identifier, date of creation, or the main topic of the document.

Information retrieval (IR) is the activity of obtaining information system resources that are relevant to an information need from a collection of those resources.

Searches can be based on full-text or other content-based indexing. Information retrieval is the science of searching for information in a document, searching for documents themselves, and also searching for the metadata that.

Components of a traditional information retrieval system experiment include the: 1. indexing system – indexing and searching methods and procedures (an indexing system can be human or automated). collection of documents – text, image or multimedia documents, or document surrogates (for example bibliographical records).

It is a part of information science, which studies of those activities relating to the retrieval of information. Searches can be based on metadata or on full-text indexing.

Subject indexing is and retrieval of scientific information book act of describing or classifying a document by index terms or other symbols in order to indicate what the document is about, to summarize its content or to increase its other words, it is about identifying and describing the subject of indexing.

Indexes are constructed, separately, on three distinct levels: terms in a document such as a book; objects in. The purposes of documentation and the statistical nature of scientific information.

Multimedia Information Retrieval (MIR) is an organic system made up of Text Retrieval (TR); Visual Retrieval (VR); Video Retrieval (VDR); and Audio Retrieval (AR) systems.

So that each type of digital document may be analysed and searched by the elements of language appropriate to its nature, search criteria must be extended. The need for new indexing and retrieval methods at the time was twofold. First, a huge number of technical reports and other scientific literature, gen-erated byresearch conducted for World War II, indicated the inadequacy of theexisting indexing and retrieval systems, which were primarily manual.

Information retrieval (IR) is the science of searching for information in documents, searching for documents themselves, searching for metadata which describe documents, or searching within hypertext collections such as the Internet or intranets.

IR is further analyzed to text retrieval, document retrieval, and image, video, or sound is an interdisciplinary scientific field based. Clus­ tering has been used in information retrieval for many different purposes, such as query expansion, document grouping, document indexing, and visualization of search results.

In this book, we address issues of cluster­ ing algorithms, evaluation methodologies, applications, and architectures for information retrieval.
