Review Questions

• How does natural language processing enhance human-computer interaction?
  • Natural language processing enhances human-computer interaction by allowing computers to understand and respond to human language in a way that feels intuitive. This means users can communicate with machines using everyday language rather than requiring specific commands or programming languages. As a result, tasks like searching for information or automating customer service become much easier and more efficient.
• Discuss the applications of natural language processing in fields such as marketing and healthcare.
  • In marketing, natural language processing is used for sentiment analysis to gauge consumer opinions about products and services from social media or reviews. This allows companies to tailor their strategies based on customer feedback. In healthcare, NLP aids in analyzing vast amounts of unstructured patient data from electronic health records to improve patient care, identify trends, and enhance decision-making processes by extracting meaningful insights.
• Evaluate the implications of advancements in natural language processing on the future of work and communication.
  • Advancements in natural language processing are poised to significantly reshape the future of work and communication by automating routine tasks, improving efficiency, and enabling new forms of interaction between humans and machines. As NLP technology continues to evolve, it will facilitate more personalized and context-aware communication tools. This can lead to job displacement in some sectors but also create new opportunities for innovation and roles focused on overseeing AI systems, enhancing human capabilities rather than replacing them.
