Evorus Your Crowd-Powered Conversational Assistant

Sure, you can check your schedule or ask some soulless algorithm a question, but its more fun to chat with your computer while getting what you need.


(Evorus Your Crowd-Powered Conversational Assistant)

Crowd-powered conversational assistants have been shown to be more robust than automated systems, but do so at the cost of higher response latency and monetary costs. A promising direction is to combine the two approaches for high quality, low latency, and low cost solutions. In this paper, we introduce Evorus, a crowd-powered conversational assistant built to automate itself over time by (i) allowing new chatbots to be easily integrated to automate more scenarios, (ii) reusing prior crowd answers, and (iii) learning to automatically approve response candidates. Our 5-month-long deployment with 80 participants and 281 conversations shows that Evorus can automate itself without compromising conversation quality. Crowd-AI architectures have long been proposed as a way to reduce cost and latency for crowd-powered systems; Evorus demonstrates how automation can be introduced successfully in a deployed system. Its architecture allows future researchers to make further innovation on the underlying automated components in the context of a deployed open domain dialog system.

(Cooperating with Machines [abstract])

In his excellent 1977 novel The Dosadi Experiment, Frank Herbert describes the Daily Schedule, a chatty computer scheduler with its share of helpful associations.

In McKie's thoughts, the DS [Daily Schedule] was suddenly transformed into a valued confidante.

As though it knew his thoughts, the DS said:

"I'm still a machine. You are inefficient, but as you have correctly stated you have ways at arriving at accuracy which machines do not understand. We can only... guess, and we are not really programmed to guess unless specifically ordered to do so on a given occasion. Trust yourself."

"But you'd rather I were not killed?"

"That is my program."

"Do you have any more helpful suggestions?"

"You would be advised to waste as little time as possible here. There was a tone of urgency in BIldoon's voice."

McKie stared at the nearest voder...

"Are you sure he sounded urgent?"

"He spoke rapidly and with obvious tensions."

"Truthful?"

"The tone-spikes lead to that conclusion."
