In this paper, we present the results of a project that seeks to transform low-level features to a higher level of meaning. This project concerns a technique, latent semantic indexing (LSI), in conjunction with normalization and term weighting, which have been used for full-text retrieval for many years. In this environment, LSI determines clusters of co-occurring keywords, sometimes, called co...

Keyword reduction is a technique that removes some less important keywords from the original dataset. Its aim is to decrease the training time of a learning machine and improve the performance of text categorization. Some researchers applied rough sets, which is a popular computational intelligent tool, to reduce keywords. However, classical rough sets model, which is usually adopted, can just ...

For better data availability and accessibility while ensuring secrecy, organizations often tend to outsource their encrypted the cloud storage servers, thus bringing challenge of keyword search over data. In this article, we propose a novel authorized scheme using Role-Based Encryption (RBE) technique in environment. The contributions article are multi-fold. First, it presents which enables onl...

This thesis in the field of cryptography considers secure data outsourcing with keyword search capabilities. To ensure data confidentiality the data is stored in encrypted format. An efficient solution has been developed to enable conjunctive keyword search. Also, a protocol is applied to enable efficient and secure sharing of encrypted data. It is possible to efficiently enrol and revoke users...

Most existing XML stream processing systems adopt full structured query languages, such as XPath or XQuery, but they are difficult for ordinary users to learn and use. Keyword search is a user-friendly information discovery technique that has been extensively studied for text documents. This paper presents an XML stream filter system called XKFilter, which is the first system for supporting key...

abstractalthough the biokinetics, metabolism, and chemical toxicity of uranium are well known, until recently little attention was paid to the potential toxic effects of uranium on reproduction and development in mammals. in recent years, it has been shown that uranium is a developmental toxicant when given orally or subcutaneously (sc) to mice. decreased fertility, embryo/fetal toxicity includ...

The automatic speech recognition currently arouses a great interest. In particular, the keyword detection which constitutes a signi cant branch of the human-machine interaction and which can help us to communicate with our machines in a natural and direct way by using spontaneous speech. This technique consists in detecting in a pronounced sentence, the keywords characterizing the application a...

– In this paper, we present the results of our work that seeks to negotiate the gap between low-level features and high-level concepts in the domain of web document retrieval. This work concerns a technique, latent semantic indexing (LSI), which has been used for textual information retrieval for many years. In this environment, LSI determines clusters of co-occurring keywords, sometimes, calle...

Information on the web is increasing every minute. Redundancy in information is growing rapidly. Data mining is the technique used to extract this data as per the user’s query. Technically data mining analyzing and summarizing it into useful information. Keyword search is an important tool for exploring and searching large data corpuses whose structure is either unknown, or constantly changing....
