Searching documents using keywords is a very common practice. This practice of word-based information retrieval is affected by two complimentary problems. First is, we may get some relevant as well as some irrelevant search results if we use the keyword along with some possible meaning of the same for the search. Second is, if only the title keyword is used then some relevant text may miss out as some times the text related to that keyword doesn’t contain that rather contains some context of that.
We aim at using Word Sense Disambiguation for text classification in which all the non-stop-words will be tagged with their senses relative to the text in the document and these senses are later selected as classes for the given document. Accordingly, there will be a common class for all the related text and hence can be searched better. We shall use WorldNet to extract the correct senses of the ambiguous non-stop-words. The classification results thus obtained shall later be evaluated by comparing with the classification results of manual disambiguation.

Introduction
The explosion of the Analog communications industry has led to many developments in design of transrecievers. The Multi standard transceivers used these days for these systems should be able to operate over a wide frequency range with minimal amounts of duplicated hardware. A very critical element of any type of transceiver is the frequency synthesizer (FS). A special frequency synthesizer i.e. multi-standard frequency synthesizer must be able to synthesize different bands of frequencies for the different wireless standards....

1. What is the name of the document? Ida Tarbell Criticizes Standard Oil (1904) 2. What type of document is it? (newspaper, map, image, report, Congressional record, etc.)
Titles are usually skipped over. A reader thinks that almost no information can be found in the title considering
The effect is that the title pulls the reader in because the title is short and sharp, also its makes the reader excited.
There are other precursors like the Novachord and the Ondes Martenot, which used a sliding metal piece in addition to a keyboard to create pitches, but it wasn’t until 1964 that Robert Moog released the first voltage controlled synthesizer. Moog said in his documentary: Synthesizer Documentary ~ Moog by Hans Fjellestad:
I found that PsycINFO database from Ovid is useful and reliable as apart from providing clear reference details for every text, it highlights keywords in search results, and this really raise efficiency. The following three research papers are the most relevant sources for this topic.
In this paper, a wideband CMOS realization of the CCII based on the long tail differential pair with rail to rail input stage is designed to improve the dynamic range.

The main characteristic of web writing that makes it different from traditional writing is the use of keywords, the words and phrases most likely to be used by readers as they search for information on the web. The Internet is an environment where we read and consume information in a manner that is different from the traditional or conventional. However, with the Internet becoming the primary mode of gathering information, knowledge of these patterns and behaviors is very important for anyone aiming to get information out to readers

The field of Computational Linguistics is relatively new; however, it contains several sub-areas reflecting practical applications in the field. Machine (or Automatic) Translation (MT) is one of the main components of Computational Linguistics (CL). It can be considered as an independent subject because people who work in this domain are not necessarily experts in the other domains of CL. However, what connects them is the fact that all of these subjects use computers as a tool to deal with human language. Therefore, some people call it Natural Language Processing (NLP). This paper tries to highlight MT as an essential sub-area of CL. The types and approaches of MT will be considered, and limitations discussed.

Nowadays, information is the cornerstone of the modern enterprise and the web became the largest and most accessible information resources. The ability to gather, arrange, manipulate information with computers has given practice as well as for business people in order to manage information in an effective way. Information retrieval is a process and techniques of searching and interpreting information in order to store the data for easy retrieval when needed. The development of information retrieval systems is reviewed from its early history to the present time. The article entitled “Seven Ages of Information Retrieval”, written by Michael Lesk explained about the history or the beginning of information retrieval based on the imaginary of Vannevar Bush’s 1945 and theory of Warren Weaver in 1949 and the author try to relate with ideology of Shakespeare 1955 which is seven ages of man, starting from infancy and leading to senility. This article gives useful information about transformation of information retrieval. From my observation, there have many important elements that have been discussed in this article but what are really give impact to me is people, theory and transformation.
