Word-Based Information Retrieval

2553 Words6 Pages

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....
