Multimodal sentiment analysisMultimodal sentiment analysis is a technology for traditional text-based sentiment analysis, which includes modalities such as audio and visual data. It can be bimodal, which includes different combinations of two modalities, or trimodal, which incorporates three modalities. With the extensive amount of social media data available online in different forms such as videos and images, the conventional text-based sentiment analysis has evolved into more complex models of multimodal sentiment analysis, which can be applied in the development of virtual assistants, analysis of YouTube movie reviews, analysis of news videos, and emotion recognition (sometimes known as emotion detection) such as depression monitoring, among others.

Freedom of the pressFreedom of the press or freedom of the media is the fundamental principle that communication and expression through various media, including printed and electronic media, especially published materials, should be considered a right to be exercised freely.

It is in opposition to paid press, where communities, police organizations, and governments are paid for their copyrights.
