Sentiment Analysis is the process of determining whether a piece of writing is positive, negative or neutral. It’s also known as opinion mining, deriving the opinion or attitude of a speaker. A common use case for this technology is to discover how people feel about a particular topic.
Say you want to know if people on Twitter think that Chinese food in San Francisco is good or bad.
Twitter sentiment analysis will answer this question. You can even learn why people think the food is good or bad, by extracting the exact words that indicate why people did or didn't like the food. If
too salty shows as a common theme, for example, you immediately have a better idea of why consumers aren’t happy.
This is the kind of insight one aims to find through market research, but why devote enormous budgets and countless man-hours to conducting surveys and cold calling? Through Lexalytics text mining tools, you’ll get answers in seconds from the comfort of your office chair.

Lexalytics’ sentiment analysis techniques can be configured to determine sentiment on a range of levels. We’ll score sentiment on a document level (does this express a general positive or negative tone), but we’ll also score the sentiment of individual words or phrases in the document.
Less precise sentiment analysis tools lump together the sentiment expressed at individual entities into a general document sentiment score. Given a Facebook comment that reads:
I love the summer in New York, but I hate the winter.A weak sentiment analysis system will score
love the summeras positive and
hate the winteras negative, but will report the entire comment’s sentiment as neutral (the positive
loveand the negative
hatecancelling each other out). Lexalytics recognize the importance of that middle word,
but, and so we report separate sentiment for the first and second parts of the sentence.
