sentiment analysis

Sentiment analysis is a way to figure out how people feel about something by analyzing their writing or words. It works by looking for certain words or phrases in what a person has said, and then using those words or phrases to decide whether the person feels positively or negatively about the thing they are talking about. For example, if someone writes that they "love" something, that usually implies they feel very positively about it.
