In this paper we investigate some of the most important variants of information retrieval. CLIR deals with submitting queries in one language and retrieving documents in some other language other than query language. MLIR deals with submitting questions in one or more languages and retrieving documents in one or more diverse languages.

Information storage and retrieval

Information retrieval processing. An information retrieval system for collections of unstructured text can be viewed as a set of processing modules, beginning with lexical analysis of documents and leading ultimately to a retrieval process in which user queries are matched against documents.

The processes which make up an information retrieval system are referred to as information retrieval operations. In some cases, the end goal is not the retrieval of matching documents from a collection but an auxiliary application, such as document categorization, summarization, or filtering of information from an information stream.

While the basic operations in information retrieval systems are similar, there can be considerable variability in the model or details of implementation, making evaluation of information retrieval system effectiveness an important step.

Summary: The technological advancements in computer networks and the substantial reduction of their production costs have caused a massive explosion of digitally stored information. In particular, textual information is becoming increasingly available in electronic form. Finding text documents dealing with a certain topic is not a simple task. Users need tools to sift through non-relevant information and retrieve only pieces of information relevant to their needs. The traditional methods of information retrieval IR based on search term frequency have somehow reached their limitations, and novel ranking methods based on hyperlink information are not applicable to unlinked documents. The retrieval of documents based on the positions of search terms in a document has the potential of yielding improvements, because other terms in the environment where a search term appears i. That is to say, the grammatical type, position and frequency of other words help to clarify and specify the meaning of a given search term.

Фонтейн кивнул. Агенты связались с ним, когда он находился в Южной Америке, и сообщили, что операция прошла неудачно, поэтому Фонтейн в общих чертах уже знал, что случилось. Тут вступил агент Колиандер: - Как вы приказали, мы повсюду следовали за Халохотом. В морг он не пошел, поскольку в этот момент напал на след еще какого-то парня в пиджаке и галстуке, вроде бы штатского.

Тогда она взяла послание домой и всю ночь просидела под одеялом с карманным фонариком, пытаясь раскрыть секрет. Наконец она поняла, что каждая цифра обозначала букву с соответствующим порядковым номером. Она старательно расшифровывала текст, завороженная тем, как на первый взгляд произвольный набор цифр превращался в красивые стихи. В тот момент она поняла, что нашла свою любовь - шифры и криптография отныне станут делом ее жизни. Почти через двадцать лет, получив степень магистра математики в Университете Джонса Хопкинса и окончив аспирантуру по теории чисел со стипендией Массачусетского технологического института, она представила докторскую диссертацию- Криптографические методы, протоколы и алгоритмы ручного шифрования.
