Now searching over one million sentiment patterns

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.

Why use RaveRants?

Suppose it’s Friday night, you’re walking downtown, and you’d like to determine which movie to see. If you tried to use a movie rating site like IMDB or Rotten Tomatos, you would have very little content. Why? They don’t update in realtime. And they require users to spend a great deal of time crafting their review. It takes time for these reviews to accumulate.

RaveRants is different. It treats tweets as reviews. Reviews accumulate fast, since it’s easy to tweet out “I’m hating X movie” when you’re still in the theater. RaveRants also indexes reviews in near realtime. This means that RaveRants lets users search on the latest reviews seconds after they occur.

Because of this, RaveRants is ideal for reviews on breaking topics such as recently released movies, TV shows, clubs, books, products, software, games, and web sites.

Another problem with review sites is that they’re silo’d. Back to the Friday night example: does it really make sense to visit Yelp to find a restaurant, IMDB for movies, and so on? Not at all.

RaveRants provides a single site for reviews on any topic you can imagine: movies, TV shows, bands, concerts, albums, software, books, political candidates, ballot measures, products, celebrities, cars, restaurants, clubs, airlines, travel destinations, hotels, local businesses, and power tools.

As a result, RaveRants competes with Yelp, Amazon.com, Epinions, Zagat, IMDB, Rotten Tomatoes, Netflix, and a host of other companies. It is crazy to have that many competitors? Not at all, in our book.

What is RaveRants?

RaveRants is a web-based service that lets you search Twitter for opinion on just about anything: movies, shows, bands, celebrities, products, companies, sports teams, politicians, and more.

RaveRants summarizes how many positive and negative tweets that something has. If you’re searching for a movie, product, band, or show, you can use RaveRants to quickly determine whether it’s worth pursuing.

RaveRants also clusters positive and negative tweets about a particular thing, and lets you quickly ask follow-up questions to each tweet’s author. This helps you get more in-depth information about a product, movie, or band.

Our mission: To organize twitter’s opinions and make them universally accessible and useful. Give it a try and let us know what you think!

Hola world

Woohoo! RaveRants is now live. Barely. But it works.

Even in its current embryonic state, RaveRants provides some decent insights into how Twitter users feel. Here are a couple:

• Obama v. Bush: Barack has many more positive than negative tweets, currently about 92% positive. This is way up from before he won the Nobel prize, where it was about 50/50 in terms of positive and negative tweets. However, most of these tweets are supporters of the president who think he didn’t deserve the Nobel. Sorry George Bush fans. The Ex has a low rating on Twitter, with only 21% positive tweets.
• Adidas v. Nike: Twitterers like Adidas more than Nike. Adidas currently has 91% positive tweets, versus 77% for Nike. Nike’s rating is pulled down by twitterers who are mostly concerned about sweatshops. Evidence that corporate social responsibility concerns impact brand affinity.
• Coke v. Pepsi: Currently, Coke barely leads Pepsi, with a 65% approval rating versus 59% for Pepsi.

Since Twitter is realtime, these results change minute-by-minute. But that’s the fun thing about RaveRants. It’s a constantly changing view of real-time sentiments of online users.

So, enjoy!

Just don’t beat on RaveRants too hard. And be patient. We know it’s not that fast. It will get better. Promise.
