Generative AI has created new opportunities for improving public services. Governments are testing AI chatbots to provide advice on benefits, taxes, and other issues. Early chatbots had limited abilities, but newer models promise human-like responses. However, mistakes or “hallucinations” still occur.
For example, the UK’s GOV.UK Chat is based on ChatGPT and aims to help citizens with a range of questions. Though 70% of users found it helpful, it sometimes provided incorrect information. Similar efforts are happening in Portugal, where an AI chatbot offers legal advice but struggles with complex questions. Experts advise caution, suggesting that chatbots should complement rather than replace human workers.
Introduction of AI in Government Services
Long before ChatGPT showed up, governments were already thinking about using chatbots. They thought chatbots could help make services faster and easier to access. Early chatbots were simple. They had limited abilities to chat. Colin van Noordt, who studies AI in government, says these early chatbots couldn’t do much besides basic tasks.
In the last two years, generative AI has sparked new hope for better public services. Generative AI can offer human-like responses to questions about things like benefits and taxes. This AI works 24/7. It could handle various citizen inquiries. But it’s not all smooth sailing. Generative AI is known to make mistakes. Sometimes, it gives silly or nonsensical answers. These mistakes are called “hallucinations.”
Case Study: The UK’s GOV.UK Chat Experiment
The UK Government Digital Service (GDS) has been testing a ChatGPT-based chatbot called GOV.UK Chat. This chatbot answers citizens’ questions on government services. Nearly 70% of users in the trial found the responses helpful. However, some problems arose. The chatbot occasionally gave incorrect information and presented it as fact.
Accuracy is crucial for government websites like GOV.UK. Inaccurate answers can lead to serious issues. GDS is quickly working to fix these problems. They aim to improve the accuracy and reliability of the chatbot. The goal is to make the chatbot a trustworthy tool for the public.
Portugal’s Justice Practical Guide
Portugal is also exploring the use of AI-driven chatbots. In 2023, they launched the Justice Practical Guide. This chatbot answers basic questions about marriage, divorce, and setting up a company. It’s based on OpenAI’s GPT 4.0 and funded by the European Union’s Recovery and Resilience Facility (RRF).
The project cost €1.3m and in its first 14 months, it handled over 28,000 questions. The chatbot did well with simple questions like setting up a company. But when asked trickier questions, it struggled. For instance, it couldn’t answer if a person under 18 but married could set up a company. A ministry source admits there’s work to do. They need to increase the chatbot’s trustworthiness.
They hope to boost the chatbot’s confidence levels soon. Right now, rare mistakes happen, but they aim to reduce these errors. Accurate information is key, especially when dealing with legal matters. Therefore, they are continually working on improvements.
Expert Opinions and Cautions
Experts advise caution when using chatbots to replace human workers. Colin van Noordt believes chatbots should be an additional service, not a replacement. They can be a quick way to find information, but they shouldn’t replace real people.
Sven Nyholm, a professor at Munich’s Ludwig Maximilians University, points out the issue of accountability. A chatbot cannot be accountable or morally responsible for its actions. Human beings in public administration are needed for their ability to be accountable. This is an essential aspect of government services.
Nyholm also emphasizes the problem of reliability. New chatbots may seem smart, but they make mistakes. These mistakes can be funny, but sometimes they can be dangerous. People need to be careful about depending on AI chatbots for important advice.
Estonia’s Unique Approach
Estonia has been a leader in digitizing public services since the early 1990s. Estonia introduced digital ID cards back in 2002. These cards allow citizens to access state services easily. Now, Estonia is developing a suite of chatbots for state services called Bürokratt.
Unlike other countries, Estonia’s chatbots use Natural Language Processing (NLP). These chatbots break down requests into small parts and identify keywords. Then, they figure out what the user wants. If the chatbot doesn’t know the answer, a human customer support agent takes over.
Kai Kallas, who leads the Personal Services Department at Estonia’s Information System Authority, says this method keeps the process transparent. It ensures citizens get the correct information, even if a chatbot can’t provide it. This cautious approach helps to avoid the errors seen in LLM-based chatbots.
Comparing Different AI Models
Early chatbots often forced people to pick options for their questions. This provided more control and transparency in how the chatbot worked. It also ensured the chatbot’s answers were more predictable.
Generative AI chatbots offer more conversational and detailed responses. But this comes with risks. They can provide different answers to the same question. This lack of consistency can be problematic, especially for government services.
Colin van Noordt explains that while LLM-based chatbots are impressive, they lack control. They can imitate human speech, but they can also make errors. This balance between conversational quality and accuracy is crucial. More research and improvements are needed to make these AI systems reliable for public use.
Ongoing Efforts and Future Prospects
Governments around the world are not giving up on AI chatbots. They see the potential for AI to revolutionize public services. Continued efforts are being made to improve the accuracy and reliability of these chatbots. It’s clear that AI has a role to play, but it’s not yet ready to replace human workers entirely.
In conclusion, the introduction of AI in government services marks an exciting yet challenging development. While AI chatbots have the potential to enhance accessibility and efficiency, they are not without their flaws. Ensuring the accuracy and reliability of these systems is paramount. Experts stress the importance of using AI as a supplementary tool, rather than a replacement for human workers.
Experiments in the UK, Portugal, and Estonia illustrate the nuanced journey of AI integration in public services. While generative AI chatbots show promise, they also exhibit limitations that require careful oversight. By learning from these experiences, governments can better harness the advantages of AI, while minimizing risks. Future advancements should focus on refining these technologies to improve their reliability, ensuring that they serve the public effectively and ethically. The road ahead is paved with both opportunities and challenges, but with diligent effort, AI can significantly contribute to improved government services.
