The news social media websites provide is nearly in a textual format which is considered as unstructured text. Text mining is particularly used as the way of bringing out indefinite and practical models or information from a summation of enormous and unstructured data or corpus. Computational linguistics, Information Retrieval (IR) and data mining are some research fields that are being incorporated by one of the branches of data mining named text mining, scholars stated. A good number of text mining techniques such as ‘topic detection and tracking, keyword extraction, sentiment analysis, document clustering, and automatic document summarization’ have been introduced to increase the efficiency of analyzing text.

Data was collected through the SAMSUNG mobile Facebook page. By using ‘NCapture for NVivo 10’ 128,371 comments were captured that represented the corpus of research from 10th June to 10th September.
The structured approach has been suggested by the researchers to analyze social media data that include only the comments in English language.
