What Is AI Engine and Do I Need It?

Chatbots and assistant programs designed to support conversations with human users rely on natural language processing (NLP). This is a field of scientific research that aims at making computers understand the meaning of sentences in natural language. The algorithms developed by NLP researchers helped power first generation of virtual assistants such as Siri or Cortana. Now the same algorithms are made available to the developer community to help companies build their own specialized virtual assistants. Industry products that offer NLP capabilities based on these algorithms are often called AI engines.

The most powerful and advanced AI engines currently available on the market are (in no particular order): IBM Watson, Google DialogFlow, Microsoft LUIS, Amazon Lex.

All these engines use intents and entities as primary pnguistic identifies to convey the meaning of incoming sentences. All of them offer conversation flow capability. In other words, intents and entities help to understand what the incoming sentence is about. Once the incoming sentence is correctly identified you can use the engine to provide a reply. You can repeat these two steps a large number of times, thus creating a conversation, or dialog.

In terms of language processing ability and simplicity of user experience IBM Watson and Google DialogFlow are currently above the pack. Microsoft LUIS is okay too; still, keeping in mind that Microsoft are aggressively territorial and like when users stay within their ecosystem, it is most efficient to use LUIS together with other Microsoft products such as MS Bot Framework.

Using AI engine conversation flow to create dialogs makes building conversations a simple, almost intuitive, task, with no coding involved. On the flip side, using AI engine conversation flow limits your natural tendency to make conversations natural. The alternative, delegating the conversation flow to the business layer of your chatbot, adds richness and flexibility to your dialog but makes the process more comppcated as it now requires coding. Cannot sell a cow and drink the milk at the same time, can you?

Amazon Lex lacks the semantic sophistication of their competitors. One can say (somewhat metaphorically) that IBM Watson was created by linguists and computer scientists while Amazon Lex was created by sales people. As a product it is well packaged and initially looks pleasing on the eye, but once you start digging deeper you notice the limitations. Also, Amazon traditionally excelled in voice recognition component (Amazon Alexa) and not necessarily in actual language processing.

The space of conversational AI is fluid and changes happen rapidly. The existing products are evolving continuously and a new generation of AI engines is in the process of being developed.

Travel Chatbots Update

These are early days for travel bots. They mostly specialize in customer service, customer information and sometimes online booking. Advanced AI technology is good and getting better by the day, but it does not replace a person. And that's unlikely to change for a while.

In order to create a positive and enjoyable experience it is imperative to have a clear understanding of what bots do well and what they don’t.

One area where they have clear advantage over humans is response speed. Using bots makes your travel business scalable. Bot can handle mutlple user conversations simultaneously and replies instantly.

The part of the bot technology that needs significant improvement is understanding of the meaning of what customer said. The solution is to take the user off the bot when this stage of the converastion is reached. One of the popular techniques is to redirect the user from bot to the website when the questions get complicated. The majority of users are at ease with website navigation where they find themselves in the familiar environment.

This approach allows to utilize the scalability of the chatbot while maintaining the high level of customer service.

nmodes Is Helping Businesses to Succeed

With the launch of the new dashboard nmodes is helping businesses to drive traffic and grow sales.

For example, One of our clients needed to increase traffic to their website while at the same time improve the conversion rate. In other words, they wanted to see more quality traffic.

The client made a concentrated effort on social media, however they were having difficulties in finding the target audience - traditional keywords search resulted in too much noise and did not produce desired outcome.

nmodes dashboard simplified this client’s engagement process. We created a dedicated stream that accurately addressed their targeted audience. nmodes dashboard is actionable, so their engagement became easy. nmodes technology identifies potential customers accurately, and so their engagement became efficient.

As a result, the click thru rate rose up to 65%, traffic quality improved by 25%, and conversion increased to 6-8%

Another client relied heavily on mainstream dashboards (such as Hootsuite) These tools do not do a good job finding relevant conversations, in the process producing too much noise and forcing client’s community managers to spend long hours manually identifying these relevant conversations. The client manages multiple social account and this type of manual labour was impeding the business, both in terms of costs and efficiency.

nmodes produces highly accurate results in finding relevant conversations that do not require manual clean up. The client started using nmodes solution, and immediately freed a substantial amount of hours which enabled them to consecrate on servicing their customers and acquiring new ones.
