What key AI component enables modern mental health chatbots' contextual awareness?
Answer
Natural Language Processing (NLP)
The vast technological gap between ELIZA and modern mental health chatbots is bridged by significant advances in Artificial Intelligence, most notably in Natural Language Processing (NLP). While ELIZA relied on recognizing keywords via scripted rules, contemporary systems use NLP, machine learning, and deep learning models. These newer models allow the chatbots to move beyond mere pattern recognition to achieve a level of contextual awareness and statistical modeling of language, enabling them to maintain context throughout an interaction.
