Solution Description

Problem description

Citizens often struggle to navigate the complex agendas of the Ministry of Labour and Social Affairs, while call centers are overloaded with a high volume of inquiries. Manual handling of questions is time-consuming, increases administrative burden, and reduces efficiency. The project addresses this challenge through an AI assistant that automates responses to frequently asked questions and enables quick escalation of more complex cases to human operators.

Solution

The project introduces a digital assistant for the Ministry of Labour and Social Affairs in the form of a chatbot and voicebot to provide citizens with verified public information. The assistant leverages retrieval-augmented generation (RAG), semantic search, and speech recognition for fast, consistent, and accessible communication. The goal is to provide citizens with reliable 24/7 answers, reduce the workload of call centers, and improve the efficiency of government–citizen communication.

The deployment has significantly reduced the burden on call centers and has been positively received by both the public and the MoLSA staff.

Biggest Challenges

Recommendation for Others

In our practice of deploying AI systems to support organizations, we often encounter situations where clients attempt to address or optimize their challenges and processes using commonly available tools. However, these tools are usually designed as universal solutions, which in practice often leads to issues with accuracy, reliability, and overall efficiency. Our goal is to prevent such shortcomings already at the solution design stage. Thanks to our experience and proven methodologies, we are able to guide the client smoothly and effectively through the entire implementation process—from needs analysis to the deployment of tailored tools.
