We’re going to see nearly 70 companies launching new products on stage. They’re shaking up industries from dating to healthcare to real estate and consumer electronics. And speakers from industry titans and upstarts will share their views of the battlefield. You’re not going to want to miss this DEMO.

The havoc is being defined by three trends:

• the shifting of our lives to mobile;
• the morphing of the Web to something truly social;
• and the porting of data processing to the cloud.

After a two-day feast of ideas, we’ll wrap it up on Wednesday evening with a wrap party featuring the legendary DEMO Jam Band at Avalon in Santa Clara, which will go from 8 p.m. to past midnight. We’ll be opening the stage to attendees brave enough to jump in.

Another great reason to be there is the conversation and networking that will take place throughout the show. In the hallways, you’ll run into the nation’s top tech press, the hungriest venture capitalists, the sharpest corporate-development executives, and chief information officers with open pocketbooks.

While informal chatter flows outside the main stage, we’ll be having high-level conversations with some of the industry’s sharpest minds. If the industry’s state of flux is an action movie, these guys are in the director’s chair. They are leading the awesome transformation of our lives by the Web, the creators of both the consumer and back-end technology that is making it all possible. (We mentioned some speakers in an earlier post, which include SAP CEO Bill McDermott, to Jack Dorsey, chairman of Twitter and CEO of Square.)

Here are the visionaries who will explain innovation’s big picture next week:

Jeff Weiner, CEO, LinkedIn

Jeff Weiner is CEO of LinkedIn, having previously worked as an entrepreneur-in-residence at Accel Partners and Greylock Partners where he advised the firm on consumer technology investments. Weiner previously served as EVP of Yahoo’s Network Division, a business with roughly $3 billion in annual revenues and more than 3,000 employees.

Weiner will talk about LinkedIn’s efforts to scale the largest professional social networking company, and gleaning insights from its 75 million users to give customers even more intelligence from their network.

Phil McKinney, Vice President and CTO, Personal Systems Group, Hewlett-Packard

HP has become one of the valley’s most voracious companies, gobbling up Palm last year in an effort to become a giant in the mobile industry, and acquiring 3Par, so that it stays on top of the cloud and storage trend we’re seeing sweep the industry.

McKinney has been dubbed “chief seer“ of HP, because he is responsible for long-range strategic planning and research and development (R&D) for all of the company’s PC product lines, including displays, mobile devices, notebooks, desktops and workstations. CIO Insight named his Killer Innovations podcast a “must-listen”.

Dave Girouard, President of Enterprise, Google

Dave Girouard manages Google’s growing enterprise business worldwide. He leads a team responsible for sales, marketing, product development and customer support. Prior to joining Google, Dave was senior vice president of marketing and business development at Virage, a provider of multimedia search and content management software. Dave also founded and developed Virage’s application services business. He came to Virage from the worldwide product marketing organization at Apple, where he spent several years in product management.

Prior to that, Dave was an associate in Booz Allen & Hamilton’s Information Technology practice in San Francisco. He started his career in enterprise systems development and integration in the Boston office of Accenture (formerly Andersen Consulting).

Sean Finnegan, Chief Digital Officer, Starcom MediaVest

A celebrated pioneer in digital media and a member of the Starcom MediaVest Group global leadership team, Sean Finnegan focuses on driving the worldwide agency network’s digital strategy and practice. In addition, he is responsible for forging digital communications products, proprietary tools and technology applications, and social and mobile media for the group.

Before joining SMG, Finnegan was chief marketing officer of Vibrant Media, a worldwide video advertising network. Prior to that, Finnegan was the chief executive officer of OMG Digital, a unit of Omnicom Media Group.

We’re inviting Finnegan to help us debate the biggest issues today around online advertising to fuel much of the Web business we’re seeing today.

Lisa Gansky, Founder, Ofoto, and GNN

Gansky is both an accomplished Silicon Valley entrepreneur and big thinker. She has just written a new book called “The Mesh” about the various ways in which new business models are emerging from the new culture of sharing, and she’ll be talking about how leaders such as Groupon, Twitter, Facebook and Zynga are exploiting this trend to market and test products in brand new ways.

Previously, as CEO, cofounder and chairman of Ofoto, Lisa drew on her entrepreneurial spirit and experience developing global Web services. Gansky and her team worked to develop Ofoto into a world-class consumer services offering, which was acquired by Kodak. She left Kodak once its Kodak Gallery reached more than 45 million customers in 2005.

Prior to her roles at Ofoto and Eastman Kodak, she was a cofounder and CEO of GNN, the Internet’s first commercial website. GNN was acquired in 1995 by AOL. She then directed Internet services for AOL through 1997.

Gansky has been an investor and board member of more than twenty Internet and mobile services companies. Currently, she serves as a board member and investor of Me Please, Squidoo, TasteBook, and Dos Margaritas, an environmental foundation. She is an advisor or investor in several new ventures including New Resource Bank, Slide, Instructables, Nuko toys, Addis Creson, and Greener World Media.

Paul Lamere writes a lot on this topic. He's a former researcher at Sun Labs where he explored ways to organize, search for and discover music. He's the author of Music Machinery, one of the best blogs out there about music and technology. Lamere now works at Echo Nest where he manages the company's developer community. Echo Nest is a music intelligence company founded by Tristan Jehan and Brian Whitman, who met at the MIT Media Lab while pursuing their doctorates in music understanding and synthesis research.

The State of Recommendation Engines is a sponsored content series by BT Buckets a leader in personalization and onsite behavioral targeting. Check out their solutions.

Lamere starts with recommendation services for the Beatles. Most services will recommend John Lennon, Paul McCarthy, The Who, Pink Floyd and other similar artists. True, these are reasonable recommendations but they do not exactly help find new music.

Lamere explains The Beatles are tremendously popular so they tend to get paired with other popular artists. The result: The recommender doesn't tell you anything you don't know. If the service looks for similar sounding music, the results won't help you either. Queen, The Rolling Stones... again, you've heard of these bands.

A different approach calls for a recommendation engine, such as what Echo Nest develops, to call on a variety of sources such as music blogs, Wikipedia entries, tags, review, profile pages, news, audio or video - the list goes on.

What ends up being recommended is a lot different than what you get when just relying on the wisdom of crowds. Echo Net recommended The Beau Brummels, The Dukes of Stratosphear, Flamin' Groovies and Emmit Rhodes.

And so Lamere asks this question: Could Emmit Rhodes be the sixth Beatle? Take a listen.

I'd say that's a pretty decent recommendation.

The wisdom of crowds should not be discounted. It plays a role in how recommendation services work. But it's the practice of stitching together multiple data sources that can find results that give you music you would not ordinarily discover.
