Taschenbuch. Zustand: Neu. Neuware - This project designed to help performing sentences based search instead of matching keywords, results will be more accurate and similar to human comprehensive search result based.The project data based on Mysql database, written I Java programming language,based on number of IR libraries. The system spitted in two project (distributed System) as follow. The indexer project: which parsing the Mysql database to be processed by the Analyzer (tokenizing ,filtering Steaming) then to store into an index file.The Searcher project which apply the input keyword to the same Analyzer applied for the indexer, then to be matched with the indexed file, then to return the matched data into Web-Pages.The IR system can return accurate search result that could ordered by percentage of relevant,thanks to using the Steamer module, by apply systematic roles on each word, to return it to its infinitive (grammatically),a new Steamer module was developed to support Arabic language ,which is still a developing topic in the area of IR Systems the project implements a full object oriented design using some advanced design theories such MVC (Model View Control and DAO (Data Access Object), multi tier design.

Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - A statisticallanguage model, or more simply a language model, is a prob abilistic mechanism for generating text. Such adefinition is general enough to include an endless variety of schemes. However, a distinction should be made between generative models, which can in principle be used to synthesize artificial text, and discriminative techniques to classify text into predefined cat egories. The first statisticallanguage modeler was Claude Shannon. In exploring the application of his newly founded theory of information to human language, Shannon considered language as a statistical source, and measured how weH simple n-gram models predicted or, equivalently, compressed natural text. To do this, he estimated the entropy of English through experiments with human subjects, and also estimated the cross-entropy of the n-gram models on natural 1 text. The ability of language models to be quantitatively evaluated in tbis way is one of their important virtues. Of course, estimating the true entropy of language is an elusive goal, aiming at many moving targets, since language is so varied and evolves so quickly. Yet fifty years after Shannon's study, language models remain, by all measures, far from the Shannon entropy liInit in terms of their predictive power. However, tbis has not kept them from being useful for a variety of text processing tasks, and moreover can be viewed as encouragement that there is still great room for improvement in statisticallanguage modeling.
