Now searching over one million sentiment patterns

January 20, 2010

People express their likes and dislikes in many different ways. Think of all the different ways you might express that you think that “X is bad” — you might say it disappointed you, or that it’s junk, or that you really, really hate it. While we as humans intuitively understand the meaning of these patterns, they explicitly need to be programmed into software.

We’re pleased to have deployed a new sentiment search algorithm that has a massive English vocabulary, which enables us to recognize over a million ways that people can express that they love or hate something. Further, we’ve reduced the time required to find all these patterns to about 20 seconds. That’s a very short time, considering all the pattern-matching that is happening.

Check out our new rollout, and let us know what you think.
