Chatbot Building with BERT for E-Commerce

Abstract

Abstract: Building a chatbot powered by BERT (Bidirectional Encoder Representations from Transform-ers) involves leveraging its pre-trained language understanding abilities to create an interface that mimics human conversation. Developed by Google, BERT marks a significant advancement in natural language processing (NLP), showcasing remarkable performance across a range of tasks. In the era of increasing artificial intelligence (AI) adoption, chatbots have emerged as crucial tools for engaging users, particularly on mobile platforms where they adapt to different contexts and communication modes, including text and voice. BERT's bidirectional architecture allows it to grasp word meanings within their surrounding context, thanks to its extensive pre-training on vast textual datasets. Fine-tuning BERT for chatbot applications involves training it on a dataset containing user queries paired with suitable responses, with annotations indicating response appropriateness. Tokenization, a crucial preprocessing step, involves breaking down sentences into smaller tokens to aid BERT's processing efficiency. The chatbot architecture integrates BERT, potentially incorporating additional layers to enhance context understanding and response generation. Following this, the model undergoes training using fine-tuned BERT on the prepared dataset, with adjustments made to hyperparameters for optimal performance. Evaluation of the chatbot typically involves testing it on a validation set or through interactive sessions to assess its effectiveness. Any necessary refinements to the architecture or finetuning process are guided by performance analysis. Ultimately, deploying the chatbot involves seamless integration into realworld platforms such as web or mobile applications, enabling smooth interaction between users and the chatbot across various scenarios, all while prioritizing originality and integrity in the development process.
