The Rise of the Unsupervised Learning-Based Chatbot Models

In the Gartner Hype Cycle of 2019, chatbots were at the peak of inflated expectations, representing premature enthusiasm and hype for the technology due to a select few success stories. Ever since their origin, chatbots were hailed as game-changers. Unfortunately, due to their inability to go beyond basic queries, they failed to sweep us off our feet.

But according to the latest reports, chatbots are all set to make a roaring comeback this year. What has changed now? Before we answer that question, let’s have a look at the chatbot evolution.

What Went Wrong, Initially?

The latest generation of chatbots has learned from these mistakes and is based on adaptive unsupervised learning. These chatbots are powered by artificial intelligence and they are built on self‑learning algorithms that learn from unlabelled data. These new‑age bots combine the advantages of previous bots in addition to unsupervised machine learning to handle complex conversations. Semantic processing enables them to understand the correlation of words and hence user intent to surface increasingly relevant responses. This is just the tip of the iceberg. Let’s see what unsupervised learning has in store for chatbots of the future.

Unsupervised Learning: What Does It Mean in the Chatbot Context?

On the contrary, AI‑fueled chatbots leverage natural language processing (NLP), among other things, for intent detection & entity extraction in user utterances. They analyze the raw data and classify it on their own. Thus, doing the heavy‑lifting, and eliminating major manual efforts.

Unsupervised, Yet Controlled Learning Is the Way to Go

In a nutshell, the chatbots based on unsupervised learning models recognize patterns and extract intent from searched data, on their own. Then, they offer intent suggestions to admins/data experts.

But what’s interesting to note is, with AI‑driven bots you also get real‑time insights that provide data on metrics such as user interaction, intents, etc.

Consider this example:
Intent one: Reward points not credited to my account

Intent two: Order history deleted for my account

If intent one gets 150 hits and intent two only 2 or 3, then you can add more utterances in intent one and make it more useful for future incoming queries. This is what makes quick and accurate user interactions possible.

Some chatbot solutions come with reports that provide the total users who interacted with the chatbot during a selected period of time. In addition to it, they offer real‑time analytics that shows current interactions. These reports not only give insights into user behavior but also assess bot performance so that you can continually tweak your bot with minimum efforts to get better results.

The Bottom Line

AI‑driven bots reduce the amount of training time, administration, and maintenance needed and still elevate the quality of customer interactions. These chatbots have multiple use cases ranging from support, services to the e‑commerce business. And the best part-very less human supervision and no manual explicit data tagging.
