Chatbot has been in existence for a very long time, but the true potential of this idea was realised with the advent of Artificial intelligence and Machine learning. As discussed earlier focus of this article is AI Chatbots and not rule-based chatbots. Now let me enlighten you with some important technologies used to create a conversational chatbot.

1. NLP- Natural Language Processing is an amalgamation of disciplines like linguistics, computer science and Artificial Intelligence. it deals with the understanding of natural languages(languages that are evolved through time among humans e.g. English, Polish, German and Hindi) by computer. Natural language processing is the soul of any AI chatbot as it enables chatbot of the two-key function those are Intent classification and Entity extraction.

Intent classification- Its an automated process of extracting the purpose of interaction that the user is engaging with a chatbot for. In simple words what the user wants from a chatbot.

Entity extraction- It is the ability of a chatbot to recognize the named entity mentioned in an unstructured conversation by the user.

for example 

user- “ book a movie at delta multiplex for two”

Here “book a movie” is user’s intent and “delta multiples” is entity.

2. Enterprise chatbot capabilities- Enterprise chatbots are scalable chatbots, that can be integrated with multiple channels and have the ability of extensive customization. They can handle huge traffic and complex tasks. Not all companies have the ability to develop enterprise chatbots. That is why this should be kept in mind while looking for an optimal developer.

3. Machine learning — Machine learning is the process of automatic improvisation of algorithms governing the functioning of particular software. In the context of Chatbot, Machine learning becomes an integral part of the backend functioning of the bot especially in the training phase of the development process.

4. Conversational AI —If NLP is the soul of a chatbot then AI is the brains. An AI-powered chatbot is a key to optimal conversational customer service. Artificial intelligence is defined as the intelligence shown by machines in contrast to natural intelligence. AI enables chatbots to be intuitive and smart. So AI capabilities of the developing platform are crucial for developing an optimal chatbot.

5. Context management- Context management is the ability of conversational chatbot to maintain and understand the context of conversion throughout the engagement. This ability is achieved through rigorous training and experimentation. Having a contextual chatbot is crucial to have quality engagement with the user.

user- “how can I develop a Chatbot?”

bot-“it is simple, just go to”

user-“what about mobile app?”

Here, the context of the conversation remained the same but the language changed. A contextual chatbot will be able to answer this question with ease.

6. Hybrid chat- Hybrid chat refers to the ability of half human-half bot customer support. To be more elaborate it is the ability of the chatbot to switch to human to human interaction when in need. A hybrid chatbot can provide an option to interact with a human to the user whenever required.

14 Commonly Asked Questions related to selecting a Chatbot Developer

Question .> What is your coding potential for chatbot development?

  • Cloud hosting- here, the developer host the chatbot on their cloud environment.

Question .> Which type of audience you want your chatbot to interact with?

A chatbot is a conversational AI software primarily developed and deployed to interact with your audience (potential customers/customers).

What are the critical requirements of your audience? How well versed is your audience?.

Question .> What will be your creative input in the chatbot development process?

Coding ability or no coding ability, your involvement with the development process is crucial. Creative input that is provided by the firm to chatbot developer is always critical when it comes to the evolution of a chatbot. 

In this regard, chatbot platforms have a slight edge over the end-to-end service provider. In the case of a chatbot platform, you can rely on the knowledge of the bot expert for optimal engagement and information is not just limited to the client’s brief and feedback only. While developing on your own or via custom developer your involvement will always be maximum. Further, developing a chatbot through an open-source NLP engine has the added risk, and drawbacks of open-source engines explained here, taking Rasa NLU as an example.

Question .> what are the past projects of your chatbot developer?

Question .>  How broad is the service spectrum of your chatbot developer?

Not all chatbot developers and platforms specialize in making chatbots catering to the needs of a particular industry. For example, finance chatbots, legal chatbots, HR chatbots, etc. you should always choose according to your needs and the specialty that the developer can provide.

Question .> What is the ownership arrangement of the chatbot?

You have to have a clear picture of your status while getting into a contractual arrangement. There are two types of ownership that developers provide.

Proprietary ownership- in this type of arrangement, you are given access to the chatbot as an end-user through an End-user license agreement(EULA). The chatbot developer wholly owns The source code. EULA usually comes with an indemnification.

Open-source- here you get complete access to the source code, and you can make changes and modify the code according to your unique needs, subjective to the open source website’s user agreement that hosts the source code (e.g., Github). Mostly open-source chatbots do not have any warranty or liability agreement.

Question .>  What are the hidden or additional costs attached to the development/maintenance of the chatbot?

The core motive for any business is to have profits, and profits require wise financial planning. Chatbot development requires investment, which is the charge paid to the developers.

Still, some costs are incurred beyond the subscription/developing fee, so to avoid the fallout of planning, this discussion should be done beforehand. It would be best if you are very thorough about all the additional costs and the services provided in the contractual agreement to avoid any miscommunication in the future.

Question .>  Can the chatbot be fully integrated with your current software/hardware infrastructure?

A chatbot is a software that requires full integration with your existing software/hardware infrastructure. Chatbot developers should always keep your current capacity and infrastructure in mind while developing the chatbot.

Question .>  What is the scalability potential of the chatbot and chatbot developer?

Scalability is even more crucial than integration; chatbot’ scalability is eminent in the modern business environment. There is no way of actually knowing the amount of traffic a chatbot would be receiving at a point in time. The developer should create and run a chatbot that can adjust to the changing environment constantly.

Question .> What are the data protection arrangements if the chatbot developer is the one hosting the chatbot?

When you host the chatbot on-premise, the responsibility and ownership of the sensitive data that the chatbot possesses are with you. But suppose the developer is the one hosting the chatbot. In that case, you have to make sure that there is adequate legal and digital protection around the sensitive data(financial, product development, or user data) handled by the chatbot.

The user data location is an essential subject for your customers as their privacy is at stake. So make sure that you have control over the data regardless of the site.

Question .>  Which third-party service your chatbot developer would be using to develop your chatbot?

There are number of service providers out there who provide open source NLP and word vectors library to create a chatbot. You should be aware of all the third-party services that your chatbot developer is using. It would be best if you gave special attention to the source code in place as there are many developers out there that use an open-source platform, which is free of cost and extract a massive fee from you.

Question .> What functionalities would your chatbot be capable of performing?

There are various functionalities that you should be looking for in your chatbot

  • Entity extraction- to extract relevant information about the critical entities mentioned in the chat by the user.
  • Intent classification- to be able to classify the intent of the user. the key reason the user is interacting with the bot in the first place

Assessment of the market needs should be a subject that your chatbot developer should be thorough with.

Question .> What happens if your chatbot stop working?
