We are beginning to understand how some of this information can be utilized to improve the users‟ experiences with interfaces and with one another. In this paper, we are interested in the personality of users. Personality has been shown to be relevant to many types of interactions; it has been shown to be useful in predicting job satisfaction, professional and romantic relationship success, and even preference for different interfaces. Until now, to accurately gauge users‟ personalities, they needed to take a personality test. This made it impractical to use personality analysis in many social media domains. In this paper, we present a method by which a user‟s personality can be accurately predicted through the publicly available information on their Twitter profile. We will describe the type of data collected, our methods of analysis, and the results of predicting personality traits through machine learning. We then discuss the implications this has for social media design, interface design, and broader domains. Keywords— personality, user profiles, personalization, cross domains and Twitter I. INTRODUCTION Social media on the web has become drastically finished the most recent decade. Social systems have turned out to be generally utilized and prevalent mediums for information dissemination and for social collaboration‟s.

People tend to comprehend others' behavior on the premise of the perception of their ordinary behavior. Tremendous number of analysts around the word has been pulled in to deal with this exploration area from various fields particularly scientists in computational phonetics, brain science, counterfeit consciousness, common dialect preparing, human-machine connection, behavioral investigation, and machine learning [3]. Utilization of social networking s has been expanded exponentially as of late. A study of social networking s assessed roughly 115 million individuals over every one of the sites on the web in January 2005, and soon after five years Twitter alone has surpassed 500 million individuals [4].
