From whom, about what, and reason why Capturing public's perception using Natural Language Processing (NLP)

In dealing with various crisis situations or other mundane events such as an introduction of a new medicine, it is important to understand the changing nature of the public’s perception to ensure that proper and relevant information is communicated amongst the public. This monitoring functionality can ensure the public’s continued support for a just cause. It is also important to assess the impact of potential misinformation, which is injected intentionally or unintentionally by the various interest bearing parties to delineate their intentions and their potential future activities.
