Building better bots requires careful consideration of several key factors. Developers should first identify the purpose and type of chatbot they want to build, whether it's transactional or conversational, and choose a suitable use case from various industries such as healthcare, finance, hospitality, retail, and sales/marketing. Next, they need to determine their bot's capabilities, including Natural Language Processing (NLP) and Natural Language Understanding (NLU), Text-to-speech (TTS), Automatic speech recognition (ASR), Dialogue management, and Human handoff. The channels or platforms where the bot will be deployed should also be considered, such as Facebook Messenger, Slack, or other popular chatbot platforms. Finally, developers need to decide whether to build a bot from scratch, use an existing platform or API, or utilize assistive APIs to streamline their development process and choose a suitable programming language like Python for its community support and AI/ML capabilities.
