Recent advances in conversational NLP : Towards the standardization of Chatbot building

arXiv.org Artificial Intelligence

Dialogue systems have become recently essential in our life. Their use is getting more and more fluid and easy throughout the time. This boils down to the improvements made in NLP and AI fields. In this paper, we try to provide an overview to the current state of the art of dialogue systems, their categories and the different approaches to build them. We end up with a discussion that compares all the techniques and analyzes the strengths and weaknesses of each. Finally, we present an opinion piece suggesting to orientate the research towards the standardization of dialogue systems building.


A Survey on Conversational Recommender Systems

arXiv.org Artificial Intelligence

Recommender systems are software applications that help users to find items of interest in situations of information overload. Current research often assumes a one-shot interaction paradigm, where the users' preferences are estimated based on past observed behavior and where the presentation of a ranked list of suggestions is the main, one-directional form of user interaction. Conversational recommender systems (CRS) take a different approach and support a richer set of interactions. These interactions can, for example, help to improve the preference elicitation process or allow the user to ask questions about the recommendations and to give feedback. The interest in CRS has significantly increased in the past few years. This development is mainly due to the significant progress in the area of natural language processing, the emergence of new voice-controlled home assistants, and the increased use of chatbot technology. With this paper, we provide a detailed survey of existing approaches to conversational recommendation. We categorize these approaches in various dimensions, e.g., in terms of the supported user intents or the knowledge they use in the background. Moreover, we discuss technological approaches, review how CRS are evaluated, and finally identify a number of gaps that deserve more research in the future.


A Unified Conversational Assistant Framework for Business Process Automation

arXiv.org Artificial Intelligence

Business process automation is a booming multi-billion-dollar industry that promises to remove menial tasks from workers' plates -- through the introduction of autonomous agents -- and free up their time and brain power for more creative and engaging tasks. However, an essential component to the successful deployment of such autonomous agents is the ability of business users to monitor their performance and customize their execution. A simple and user-friendly interface with a low learning curve is necessary to increase the adoption of such agents in banking, insurance, retail and other domains. As a result, proactive chatbots will play a crucial role in the business automation space. Not only can they respond to users' queries and perform actions on their behalf but also initiate communication with the users to inform them of the system's behavior. This will provide business users a natural language interface to interact with, monitor and control autonomous agents. In this work, we present a multi-agent orchestration framework to develop such proactive chatbots by discussing the types of skills that can be composed into agents and how to orchestrate these agents. Two use cases on a travel preapproval business process and a loan application business process are adopted to qualitatively analyze the proposed framework based on four criteria: performance, coding overhead, scalability, and agent overlap.


AI Chatbots: Reality vs. Hype - DZone AI

#artificialintelligence

Welcome to the world of intelligent chatbots: your companion and conversation agents who should make your life smarter. A leading research paper even said that by 2020, the average person would have more conversations with bots than with their spouse. So, be ready to embrace this new life in a year from now. Have you ever tried telling Siri or Google to "find restaurants that don't serve pizza?" At least they are both consistent in that they gave the same answer -- suggesting restaurants that do serve pizza. The first citizen humanoid robot, Sofia, is making her way to every media event, conducting interviews using human-like conversations. How does she compare to these competitors? Well, the truth is far from reality.


Designing a Smart Conversational Interface - Growth Tech News

#artificialintelligence

The world has witnessed significant advancements in human-computer dialogue. Today, conversational interfaces are slowly taking the place of rigid GUI dialogue boxes and web forms. The evident evolution of UI design is all about leveraging artificial intelligence to enable end-users to get answers and perform routine tasks quickly without strain. However, what's the key to designing and building AI-powered and user-friendly chat interfaces? Chatbots are programs that facilitate text-based conversations between computers and people in a natural language.
