Sentiment analysis and opinion mining in social networks present nowadays a hot topic of research. However, most of the state of the artworks and researches on the automatic sentiment analysis and opinion mining of texts collected from social networks and microblogging websites are oriented toward the binary classification (i.e., classification into “positive”and “negative”) or the ternary classification (i.e., classification into “positive,”“negative,”and “neutral”) of texts. In this paper, we propose a novel approach that, in addition to the aforementioned tasks of binary and ternary classifications, goes deeper in the classification of texts collected from Twitter and classifies these texts into multiple sentiment classes. While in this paper, we limit our scope to approx ten different sentiment classes.

Network Security deals with all aspects related to the protection of the sensitive information assets existing on the network. It covers various mechanisms developed to provide fundamental security services for data communication. Security in computer world determines the ability of the system to manage, protect and distribute sensitive information. Data Security was found many years before the advent of wireless communication due to the mankind’s need to send information without exposing its content to others. Every security system must provide a bundle of security functions that can assure the secrecy of the system. These functions are usually referred to as the goals of the security system. Most of the threat that harm the user’s sensitive information by mean of attack. One of the active attacks, i.e. Denial of Service (DoS) is harm the user’s data on network reside. Basic Description about DOS Attack Denial of Service attacks is undoubtedly a very serious problem in the Internet, whose impact has been well demonstrated in the computer network literature. The main aim of Denial of Service is the disruption of services by attempting to limit access to a machine or service instead

Multimedia communication deals with the transfer, the protocols, services and mechanisms of discrete media data (such as text and graphics) and continuous media data (like audio and video) in/over digital networks

Network Time Protocol (NTP) is very important for modern networks. NTP is a protocol designed to synchronize the clocks of computers over a network.

The Common Object Request Broker Architecture (CORBA) is a standard developed by the Object Management Group (OMG) to provide interoperability among distributed objects.

DNS spoofing occurs when a particular DNS server’s records of “spoofed” or altered maliciously to redirect traffic to the attacker. This redirection of traffic allows the attacker to spread malware, steal data, etc.

Process of Part Of Speech Tagging: Read the input sentence. Then tokenize the sentence into words. After tokenization, Suffix analysis and prefix analysis is also used for correctly tag each word of sentence.

HDLC also defines the configurations in HDLC for the three types of stations. The word configuration refers to the relationship between the hardware devices on a link.

High-level Data Link Control (HDLC) is a bit-oriented protocol for communication over point-to-point and multipoint links.

SNMP stands for simple network management protocol. It is a way that servers can share information about their current state, and also a channel through which administer can modify pre-defined values. While the protocol itself is very simple, the structure of programs that implement SNMP can be very complex.

Blowfish Algorithm is a symmetric block cipher that can be used as a drop-in replacement for DES or IDEA. It takes a variable-length key, from 32 bits to 448 bits, making it ideal for both domestic and exportable use

Raja Ram Mohan Roy is a great historical figure who put laudable efforts to transform India and dared to defy the age old Hindu traditions.

RSA algorithm is asymmetric cryptography algorithm. Asymmetric actually means that it works on two different keys i.e. Public Key and Private Key.
