Natural Language processing is an interdisciplinary branch of linguistic and computer science studied under the Artificial Intelligence (AI) that gave birth to an allied area called ‘Computational Linguistics’ which focuses on processing of natural languages on computational devices. A natural language consists of many sentences which are meaningful linguistic units involving one or more words linked together in accordance with a set of predefined rules called ‘grammar’. Grammar checking is fundamental task in the formal world that validates sentences syntactically as well as semantically. Grammar Checker tool is a prominent tool within language engineering. Our review draws on the till date development of various Natural Language grammar checkers to look at past, present and the future in the present context. Our review covers common grammatical errors , overview of grammar checking process, grammar checkers of various languages with the aim of seeking their approaches, methodologies and performance evaluation, which would be great help for developing new tool and system as a whole. The survey concludes with the discussion of different features included in existing grammar checkers of foreign languages as well as a few Indian Languages.

Visual Education Resources (VISER) is a web based Virtual Reality (VR) platform which is created to target people suffering from dyslexia and to provide them with an educative, interactive and easily accessible learning platform. This paper mainly discusses the implementation of the proposed system and an insight of how Natural Language Processing (NLP) has been used for Automatic Text Visualization (ATV) along with Web Virtual Reality (WebVR). The paper further explains how 3D avatars can be incorporated in WebVR along with their animations.

Business to Business (B2B) marketing focuses on meeting the requirement of business rather than consumers, and which make it complex business system. The B2B business strategy involves business campaign of manifested information about products or services. With widespread use of the Internet, series of different marketing processes such as searching for suitable business provider/supplier, getting contact information, make a deal with particular business provider/supplier, getting updates of business and many more are handled though web. There are many systems available providing all these processes online but not in a single window. In this paper, we are proposing a system called RATAN provides a solution in B2B business strategy. In this system, all business processes starting from searching to dealing are automated smartly in single platform. We used web crawling algorithm to deal with getting information of particular business provider and facility to contact though phone call or sending mail. We are also providing an eminent feature of automated meeting scheduler. Our system performing on real B2B marketing business and result show that the proposed system can effectively improve the quality of B2B strategy for challenging B2B tasks.

To generate large-scale resource management, grid based computing play a crucial role. It represents various geographically dispersed computational resources, i.e. workstations, PCs, cluster, storage devices, and database as fused integrated system, which can play dual roles of synchronized resource donator and consumer in such distributed computation environment. Now a day, in ubiquitous environment the use of embedded devices and mobile has grown intensively, produces abundant data which need to be processed. But, as these ubiquitous devices have limited power in terms of bandwidth, CPU, battery, storage; these applications services require more powerful computational resources. To fulfill these requirements, Grid can act as promising computational services provider to ubiquitous computing application. In this paper, we represent a competitive model, describing the interaction between Grid computational resources as competing service provider whereas ubiquitous applications as consumer. We represent Contract Net Protocol model for such competitive environment for quality of service (QoS) offered by Grid Service Provider (GSP). We have also studied model for the same competitive environment based on equilibrium behavior under definite QoS provision and the stochastic demand. Our proposed model and performance results give out appropriate strategies for real-time grid environment.
