Sentiment analysis is something very new and immature. Sentiment analysis allows you to identify general attitudes towards your brand (or a product).
The goal of sentiment analysis is to assign a given social media comment with a degree of association to three basic categories: positive, negative or neutral.
1. Social Mention
Social mention is always my first choice when it comes to the sentiment analysis. It allows to search in multiple categories including:
- Q&A sites;
- Social bookmarking sites;
- News, etc.
Socialmention’s sentiment is “the ratio of mentions that are generally positive to those that are generally negative.” They use textual analysis, emoticons, symbols to analyze the sentiment.
While many people call it flawed, SocialMention’s sentiment analysis is as good as you are currently able to get from a machine.

2. AlertRank Sentiment Analysis
AlertRank, a tool I reviewed just a few days ago, is a web based utility that adds some really great features to Google Alerts.
It allows you to configure the sentiment manually by clicking an icon next to each Google Alerts result:
After that the average sentiment is visualized via a nicely-looking graph:
