Noise is an unavoidable fact of life. It can manifest itself
Noisy unstructured text data is also found in informal settings such as online chat, SMS, email, message board and newsgroup postings, blogs, wikis and web pages. In addition to the aforementioned recognition errors, such text may contain spelling errors, abbreviations, non-standard terminology, missing punctuation, misleading case information, as well as false starts, repetitions, and pause-filling sounds such as “um” and “uh” in the case of speech.
Look up Noisy Text Analytics on Wikipedia. Do add to it if you think you can make the definition even more relevant.
