Many previous research studies on extractive text summarization consider a subset of words in a document as keywords and use a sentence ranking function that ranks sentences based on their similarities with the list of extracted keywords. But the use of key concepts in automatic text summarization task has received less attention in literature on summarization. The proposed work uses key concep...

Abstract An XML document is a collection of multiple types of data sets tagged by XML elements. Such an XML document can be retrieved not only by a Boolean connection with keywords but also by XML elementbased query languages. In many cases, however, keywords-based queries result in either too many hits or too few results. It is not trivial to formulate what to retrieve a “good” sized query-res...

Vocabulary is an important element in a language ,all the words known and used by particular person. basic need that has to be mastered students themselves. They will find it difficult speak up without having many vocabularies as memorize. In teaching vocabulary teacher should use strategy make understand meaning how voice word such asking answering, using media, etc. As far its known, there ar...

Information retrieval is one of the most important technologies at present. We can always get information in the Internet or distributed computing systems using various information retrieval models. For searching proper information that we need, it is necessary to construct efficient information retrieval agent systems helping many web clients’ requests. In this paper, we propose a simple new m...

XML files contain data which is in well formatted manner. By studying the format or semantics of the grammar it will be helpful for fast retrieval of the data. There are many algorithms which describes about searching the data from XML files. There are no. of approaches which uses data structure or are related to the contents of the document. In these cases user must know about the structure of...

Caching static HTTP traffic in proxy-caches has reduced bandwidth consumption and download latency. However, web-caching performance is hard to increase further due to the growing number of noncachable dynamic web-documents. Delta-encoding is a promising technique that exploits temporal correlation among different snapshots of a dynamic document, and renders dynamic traffic cachable. It achieve...

In many document collections, documents are related to objects such as document authors, products described in the document, or persons referred to in the document. In many applications, the goal is to find such related objects that best match a set of keywords. The keywords may not necessarily occur in the textual descriptions of target objects; they occur only in the documents. In order to an...

Information retrieval (IR) techniques become a challenge to researchers due to huge growth of digital and information retrieval. As a wide variety of Hindi Data and Literature is now available on web, we have developed information retrieval system for Hindi documents. This paper presents a new searching technique that has promising results in terms of F-measure. Historically, there have been tw...
