Communication Ebooks free: Information Retrieval

IR (Information Retrieval) is a science of searching and retrieving information or meta data from a document or database or world wide web. Information retrieval has its own applications in computer science. Automated Information retrieval systems are used for reducing information overloads. In search engines, data is retrieving more accurately and quickly by proper implementation of this Information retrieval theory. In information retrieval systems data are stored in the form of text, document, images or videos. When a user input queries for retrieving data, IR systems compare it with the data stored in the system and retrieve it quickly, accurately and with great relevance. Searching algorithms are used for this. In almost all Information Retrieval Systems, ranking of data is done with numerical values and according to the rank information is displayed.
Few open source Information Retrieval (IR) systems are Datapark Search, Lemur, MG full text retrieval System, Terrier, Zebra, Wumpus, Lucene and Zettair, etc. Some other information retrieval tools are ASPseek, iMacros, iHOP, MEDIE, Fluid Dynamics Search Engine, GalaTex, Information Storage and Retrieval using Mumps, Sphinx, Biospider and Info-PubMed etc.
