Stealth Startup Kango Working on Semantic Search For Travel

Does the world really need another travel site? With Expedia, Orbitz, Travelocity, TripAdvisor, Farecast, TripHub, Yapta, and many more, prospective travelers already have more than enough to choose from. (With an estimated $87 billion in travel booked online, it’s no wonder why). Soon they will be able to add Kango to that list.

The startup, which has been in stealth-mode until now, does manage to add a new twist to search travel. It is indexing 18 million opinions and reviews across 1,000 travel-related sites to derive the best travel search results based on what type of trip you want to take. If you are planning a romantic getaway in Big Sur, you will get one set of results. If you specify that you are looking for a family outing instead, you will get another. Or you can look for pet-friendly hotels and activities. Of course, you can also search by price or amenity, like any other travel site. And you can see where each hotel or activity is located on a small Google Map.

It parses the language in all of those reviews and guides, and categorizes them by generating tags for them. “You cannot wait for users to add tags, you have to derive them,” says CEO Yen Lee. So hotels that have been reviewed across the Web (on sites like Yahoo Travel, TripAdvisor, or Yelp) with words such as “perfect,” “relaxing,” “couples,” “honeymoon,” or “spa” would rank higher in a search for romantic travel. Hotels associated with the words “kitchen,” “pool,” and “kids,” would rank higher in a search for family trips.

Whether this will be enough to draw people from other travel sites is hard to say at this point. But Kango’s executive team has an impressive pedigree. Lee is a former general manager of Yahoo Travel. His search architect, Huanjin Chen, used to be the search architect at eBay. His natural-language search scientist, Boris Galitsky, used to do work for the British government. And his head of marketing, Elliott Ng, headed up marketing for Intuit’s QuickBooks and is the founder of Netcentives.

Lee estimates there are 6 billion to 8 billion travel-related searches done every year, and he thinks Kango can help expose more of the hidden gems in travel that today don’t quite make it to the first page of most travel sites. He plans to make money on travel-specific search advertising, rather than on booking or listing fees.

Kango will be rolling out a limited beta in the next few weeks, and is reserving 100 spots for TechCrunch readers who sign up here.

Most Useful iPhone Site Yet: Meebo

Facebook may have the best looking iPhone site to date, but Meebo for the iPhone is more useful, as it brings instant messaging, finally, to that phone. ICQ, AIM, MSN, Yahoo, and Jabber/Google are supported.

Meebo took its time building the site, which is actually their first mobile application. There is no special URL, just go to meebo.com from an iPhone and the browser will load the correct code.

The application scales either way you hold the phone (I recommend vertically to see contact, horizontally to chat - see pictures). All of your settings from Meebo are retained on the iPhone, including any avatar you’ve created. And people who you’ve had recent conversations with are always listed on the top of your buddy list.

I have a couple of complaints with Meebo. First, you still can’t access Skype text chat - a limitation of Skype, not Meebo. Also, if you leave the browser to take a call, send a text message, whatever, you are auto-logged off of Meebo and IM. This is an iPhone limitation and underscores the need for real IM chat software for the iPhone. Adium is what I use on my desktop Mac. Hopefully we’ll someday see something similar for the phone, too.

We previously covered FlickIM, which has a very nice AIM-only chat app for the iPhone. Mundu and eBuddy also have their own iPhone products as well. Mundu works well, although they may charge for it at some point; eBuddy only connects with MSN, Yahoo, and AIM.
