On the supply side, increasingly sophisticated technology will have a positive impact, both vertically among existing users and horizontally across different industries.įigure 2: Expected global market development of intelligent virtual assistants

Efficiency and productivity drivers will further catalyse this growth.
Market growth will be fuelled by further automation in sectors such as customer care and integration into daily environments such as household, mobility, finance and health. Globally, the market is forecast to be worth nearly USD 25 billion by 2027, with a compound annual growth rate of 37% ( Polaris Research, 2020). The global market for intelligent virtual assistants was estimated at around USD 2.5 billion in 2019 and is experiencing strong market growth, particularly in the US (see Figure 2). The chatbot industry is moving through early-stage growth, with investment now concentrated in mid- to later-stage investments as technology matures. This suggests that specifically focused bots are more successful than broadly focused bots, quasi "omniscient virtual assistants" ( CB Insights, 2021). Amtrak's chatbot achieved a return on investment (ROI) eight times above expectation and increased revenue per booking by just under 30%. Emirates Vacation integrated a chatbot into its display ads and increased interaction rates by 87%. The chatbots are coming and many are already here. If the question is already stored in the chatbot system or, as is often said in the chatbot world, 'the chatbot is already trained for this user question', the bot can answer the user's question directly.įigure 1: Overview of the functionality of rule-based and NLP-based chatbots Users can also type in their questions into rule-based chatbots. While an information retrieval chatbot responds to a consumer's query by repeating an appropriate answer from natural text, a machine-learned sequence transduction system learns to respond to a question with an answer ( Jurafsky und Martin, 2020). There are two subcategories of intent-based chatbots: (a) information retrieval and (b) machine-learned sequence implementation. Intent- or NLP-based bots work with Natural Language Processing (NLP) components. NLP-based chatbots evaluate human conversations and are extremely data-intensive.Online insurer Lemonade offers its entire onboarding process for customers through a rules-based chatbot.

The chatbot only comprehends buttons and cannot understand free chat – and is therefore sometimes called click-bot (Figure 1). The rule-based chatbot, as the name suggests, conducts a conversation by using predefined rules.There are two widely used types of chatbot systems - the (1) rule-based and the (B) intent-based chatbot, also called NLP bot ( Jurafsky and Martin, 2020).
A chatbot (bot for short) aims to conduct chats by mimicking unstructured conversations between humans.
