Σύνοψη	Sentiment analysis is the automated estimation of the valence — positive, negative, or neutral tone — of communication messages, adapted from natural-language processing into a core measurement technique for media and communication research. It lets scholars quantify the tone of news coverage, the affect of social-media discourse, or audience reactions across corpora far too large for hand coding, while treating tone as a measurable, validatable construct.	Framing analysis is a communication research method for studying how messages select certain aspects of a perceived reality and make them more salient — promoting a particular problem definition, causal interpretation, moral evaluation, and treatment recommendation. Building on Robert Entman's influential 1993 synthesis, it moves beyond counting what is present to reconstructing the organizing ideas, or frames, that give media coverage its meaning and persuasive shape.
