The language used in social media expresses many differences from other written genres: its vocabulary is informal with intentional deviations from standard orthography such as repeated letters for emphasis; typos and nonstandard abbreviations are common; and nonlinguistic co...

Mobile technology as well as social networking technology plays an important role in communication across internet.

This noisy information needs to be normalized into the standard text so that it can be used by the various other tools such as text-to-speec...

Steganalysis is the practice of identifying potential secret communication and taking appropriate action, such as deciphering to uncover hidden contents or destroying object containing information if it cannot be uncovered. At times, it’s very necessary perform due fact that steganography often misused by those with bad intentions, making a platform for criminal communication. This paper presen...
