Posted by cognitivecomputing in Agents, Language, Learning, Opinion, Web / Web 2.0. Tagged: , , , , , , , , , , .

We’ve hit another milestone in the Alexa Prize, a $2.5 million university competition to advance conversational AI. University teams from around the world have been hard at work to create a socialbot, an AI capable of conversing coherently and engagingly with humans on popular topics and news events for 20 minutes.

I am now excited to announce the university teams that will be competing in the finals! After hundreds of thousands of conversations, the two socialbots with the highest average customer ratings during the semifinal period are Alquist from the Czech Technical University in Prague and Sounding Board from the University of Washington in Seattle. The wildcard team is What’s Up Bot from Heriot-Watt University in Edinburgh, Scotland.

Conversational AI: Voice-Based Intelligent Agents

Posted by cognitivecomputing in Agents, Language, Learning, Opinion, Talks, Web / Web 2.0. Tagged: , , , , , , , , , .

As we moved from the age of the keyboard, to the age of touch, and now to the age of voice, natural conversation in everyday language continues to be one of the ultimate challenges for AI. This is a difficult scientific problem involving knowledge acquisition, natural language understanding, natural language generation, context modeling, commonsense reasoning and dialog planning, as well as a complex product design problem involving user experience and conversational engagement.

I will talk about why Conversational AI is hard, how conversational agents like Amazon Alexa understand and respond to voice interactions, how you can leverage these technologies for your own applications, and the challenges that still remain.

Join the Alexa Prize Journey and Test the Socialbots

Posted by cognitivecomputing in Agents, Language, Learning, Opinion, Web / Web 2.0. Tagged: , , , , , , , , , , .

On September 29, 2016, Amazon announced the Alexa Prize, a $2.5 million university competition to advance conversational AI through voice. In April, university teams from around the world assembled at the appropriately named Day 1 building in Seattle for the Alexa Prize Summit. The event was a base camp for teams to share learnings and make preparations for the most challenging leg of their journey: to build and scale an AI capable of conversing coherently and engagingly with humans for 20 minutes.

As they build their “socialbots,” they will encounter esoteric problems like context modeling and dialog planning as well as exoteric problems like user experience and conversational engagement. And they will need all the help they can get.

We invite you to join the students on their journey and help them along the way. You can interact with their socialbots simply by saying, “Alexa, let’s chat” on any device with Alexa.

Announcing the Sponsored Teams for the 2016-2017 Alexa Prize

Posted by cognitivecomputing in Agents, Language, Learning, Opinion, Web / Web 2.0. Tagged: , , , , , , , , , , , .

On September 29, 2016, Amazon announced the Alexa Prize, a $2.5 million university competition to advance conversational AI through voice. We received applications from leading universities across 22 countries. Each application was carefully reviewed by senior Amazon personnel against a rigorous set of criteria covering scientific contribution, technical merit, novelty, and ability to execute. Teams of scientists, engineers, user experience designers, and product managers read, evaluated, discussed, argued, and finally selected the ten teams who would be invited to participate in the competition. Wait, make that twelve; we received so many good applications from graduate and undergraduate students that we decided to sponsor two additional teams.

Today, we’re excited to announce the 12 teams selected to compete with an Amazon sponsorship.

The Alexa Prize: $2.5M to Advance Conversational AI

Posted by cognitivecomputing in Agents, Language, Learning, Opinion, Web / Web 2.0. Tagged: , , , , , , , , , , , .

Artificial intelligence (AI) is becoming ubiquitous. With advances in technology, algorithms, and sheer compute power, it is now becoming practical to utilize AI techniques in many everyday applications including transportation, healthcare, gaming, productivity, and media. Yet one seemingly intuitive task for humans still eludes computers: natural conversation. Simple and natural for humans, voice communication in everyday language continues to be one of the ultimate challenges for AI.

Today, we are pleased to announce the Alexa Prize, a $2.5 million university competition to advance conversational AI through voice. Teams of university students around the world are invited to participate in the Alexa Prize (see contest rules for details). The challenge is to create a socialbot, an Alexa skill that converses coherently and engagingly with humans on popular topics for 20 minutes. We challenge teams to invent an Alexa socialbot smart enough to engage in a fun, high quality conversation on popular topics for 20 minutes.

Are you up to the challenge?

A Group-Based Mobile Application to Increase Adherence in Exercise and Nutrition Programs: A Factorial Design Feasibility Study

Posted by cognitivecomputing in Health & Wellness, Web / Web 2.0. Tagged: , , .

Novel methods of promoting self-monitoring and social support are needed to ensure long-term maintenance of behavior change. In this paper, we directly investigate the effects of group support in an exercise and nutrition program delivered by an mHealth application called Fittle.

Our first specific study aim was to explore whether social support improved adherence in wellness programs. Our second specific study aim was to assess whether media types (ePaper vs mobile) were associated with different levels of compliance and adherence to wellness programs. The third aim was to assess whether the use of an mHealth application led to positive changes to participants’ eating behavior, physical activity, and stress level, compared to traditional paper-based programs.

Conclusions: The team-based Fittle app is an acceptable and feasible wellness behavior change intervention and a full randomized controlled trial to investigate the efficacy of such an intervention is warranted.

Augmented Social Cognition for Consumer Health and Wellness

Posted by cognitivecomputing in Agents, Health & Wellness, Talks, Web / Web 2.0. Tagged: , , .

In a recent Wall Street Journal essay, Marc Andreessen wrote: “Software is eating the world. Over the next 10 years, I expect many more industries to be disrupted by software. Healthcare and education are next up for fundamental software-based transformation.”

What is the impending disruption in healthcare, and what new technologies are driving it? I argue that the problem is not healthcare but health: creating new consumer-centric approaches to health and wellness that increase engagement, improve health literacy and promote behavior change.

The web is evolving from information (portals) to interaction (social/mobile) to influence: shaping attitudes and behaviors. This creates a unique opportunity to address the problem of consumer health and wellness. But, to do this effectively requires a new kind of technology: user modeling. It also requires an innovation methodology that is fundamentally about people, not technology.

At PARC, our research in Augmented Social Cognition is centered around the confluence of three technologies: social, mobile, and user modeling. I discuss these technologies and explain how we leverage artificial Intelligence (AI) and case-based reasoning (CBR) techniques to model users and create effective and sustainable behavior change.

I recently appeared on the ABC Health Report radio program.

Joel Werner: Do you ever go online to search for symptoms that you’re experiencing? I do it all the time, and it’s a trend that has picked up the nickname ‘Dr Google’. For Ashwin Ram, Dr Google is just one step on the path to future healthcare…

The Intelligent Web: Shaping Behavior at the Intersection of Health, Wealth, & Choice

Posted by cognitivecomputing in Education, Health & Wellness, Opinion, Talks, Web / Web 2.0. Tagged: , , , , .

The web is evolving from information (portals) to interaction (social/mobile). The next stage will be about influence: shaping attitudes and behaviors. To do this effectively requires a new kind of technology: user modeling. It also requires an innovation methodology that is fundamentally about people, not technology.

I discuss three big ideas in innovation for consumer engagement and behavior change, and illustrate using examples from healthcare, education, and financial services.

The Patient Portal Conundrum

Posted by cognitivecomputing in Health & Wellness, Opinion, Talks, Web / Web 2.0. Tagged: .

Recent “Meaningful Use” legislation requires healthcare providers to (Stage 1) capture patient information in electronic health records, (Stage 2) create portals to enable online access for patients and providers, and (Stage 3) demonstrate improved quality of care. All of which sounds like a great idea…but will it work?
 
At PARC we believe in anthropologist Margaret Mead‘s driving principle: “What people say, what people do, and what people say they do are entirely different things.” We know consumers access healthcare information online, but what do they actually do when they’re there?
 
NPR Marketplace cites a report by healthcare research firm National Research indicating 96% of the nearly 23,000 consumers it surveyed recently use Facebook to gather information about health care, with 28% using YouTube and 22% using Twitter. In fact, social media has been called “the biggest threat to healthcare portals like WebMD”.
 
If consumers don’t use healthcare portals, how will we get “meaningful use” by creating them? I will attempt to answer this question (hint: think Augmented Social Cognition) but I fully expect to raise a lot more questions in the process. Come ready to ask and argue, and maybe we will find answers together.
