Social media data, like other data sets, is completely unstructured and humongous in size. In order to gather insights from advanced analytics, the data needs to be preprocessed.
The major preparation work for social media data includes:
• Filtering duplicates, spam, blacklists and whitelists
• Detecting author language and country
• Analyzing sentiment by content tone and brand references
• Measuring author influences
• Indexing content and metadata
