Nowadays, chatbots (or conversational agents) are available on different platforms. It can be in a professional context (Skype, Slack) or a private one (Facebook Messenger, Discord, Telegram). Since Facebook's F8 2016 conference, these bots have become more democratic and have flooded the different platforms. They tend to replace mobile applications for their ease of use and various functionalities. In addition, there is no need to install them because they are available on apps that everyone already has.
Different uses stand out. For example, it is a way for brands to automatically answer questions from users (support, after-sales service). These bots can work as assistants for different tasks (make appointments, various automations, reminders). Online stores use it to allow people to place orders as if talking to a person. The news sites use them to distribute a summary of the articles of the day.
Thanks to the outstanding evolutions in artificial intelligence in the last decade, it is now possible to converse in a more or less natural way with bots.
This seminar focuses on investigating approaches and technologies used in today's chatbots. There are different types of bot for different uses. The techniques and technologies used vary according to the use of the bot in question. It is then worthwhile to understand the advantages and disadvantages of each of these techniques. All bots are not powered by machine learning, some are rule-based. Natural language understanding as well as natural language generation are two fundamental aspects of chatbots.Monitoring a context in a conversation is also a very important element. Analyzing and designing a human-machine interface is not an easy task. Bots can have moods and a personality. All these aspects must be considered while designing a chatbot.
A particular emphasis this year will be given to chatbots related to health and nutrition (e.g. nutritional coach, cook assistant, advisor for food related questions, recipes creator and so on).
The seminar will have a strong practical component as students will investigate existing chatbots as well as develop new concepts in the aforementioned domains. |
