Particularly in times of crisis, there is an increased need for information among the population. Public services experienced a particular stress test with the beginning of the Covid-19 pandemic. They faced the challenge of coordinating and communicating daily Covid-19 updates on protective measures and instructions to the citizens.

To relieve the burden on call centres and health advice services, and to provide citizens with targeted and quick answers to their questions, the City of Vienna used its digital assistant ‘WienBot’ to set up a ‘CoronaBot’ at the beginning of the corona crisis. Within a few days, citizens were able to access relevant information about Covid-19 via the digital assistant. In the following weeks, WienBot was continuously expanded with current information, trained and improved by the questions asked. The plan was to guide citizens through times of crisis on a channel they already trusted, and to ease the burden on call centres. This plan worked out perfectly: the City of Vienna’s digital assistant has answered more than one million questions on Covid-19 since the beginning of the corona crisis.

In 2017, Vienna was the first city in the world that launched its own intelligent voice assistant. With its development, the City of Vienna did not only respond to a digital trend; by harnessing technical innovation and placing citizens’ needs at the centre of communication, WienBot supports Vienna’s Smart City strategy. This calls for ‘high quality of life for everyone in Vienna through social and technical innovation in all areas, while maximising conservation of resources’.

Since the launch of WienBot, citizens have enjoyed using the channel and are constantly involved in its further development, for example by asking questions on relevant topics. As a result, the digital assistant is in a constant process of learning and expanding its knowledge. Furthermore, citizens are already familiar with the channel as a trustworthy source of information, which is highly beneficial during a crisis. As a mass communication channel during the crisis, WienBot played fully to its strengths by using artificial intelligence and the integration of trusted public data sources.

WienBot automatically answered thousands of questions on the current corona situation every day during the lockdown. By tailoring answers to the respective situation of the searchers, it allowed citizens to get up-to-date, verified information without having to go through a time-consuming web search. For this purpose, WienBot was trained with several thousand questions and technical terms on the topic of the corona virus; the biggest effort was to prepare the complex topic in a short and simple way. In addition, all effects of the lockdown had to be incorporated into already existing answers within a very short time. Current information (e.g. from expert sources such as AGES, the Austrian Health and Food Safety Agency) was continuously updated via interfaces to public databases, and the answers were automatically prioritised according to relevance and urgency.

Since its launch, WienBot has focused on the needs of local citizens, who are actively involved in the ongoing AI learning process via the questions they ask. Artificial intelligence analyses these new questions, and editorial review processes guarantee that WienBot constantly learns and expands its knowledge. Because of its valuable user feedback, WienBot is now a central communication channel of the City of Vienna. It is integrated in:

  • the City of Vienna app (Search)
  • gv.at-search (direct response above the search results)
  • wien.gv.at (web widget)
  • impfservice.wien (web widget)
  • allesgurgelt.at (web widget)
  • gesundheitsverbund.at (web widget)
  • Knowledge management of Vienna’s Community Service (interface)

This is also reflected in the rapidly increasing number of questions:

  • 2017: 45 000
  • 2018: 120 000
  • 2019: 2 100 000
  • 2020: 3 300 000

Since the start of the corona pandemic, WienBot has already provided 1 000 000 answers on this specific topic, which has significantly supported citizens and relieved the burden on hotlines.

The most frequently asked questions answered by WienBot on Covid-19 have been:

  • questions on test offers, e.g. ‘where/when/how can I get tested?’
  • questions on rules of conduct, contact restrictions, current measures to contain Covid-19, and quarantine regulations.

The team behind WienBot has showcased its talent several times to delegates from other Austrian cities. It has provided an exceptional case study demonstrating how valuable a digital assistant can be for a public institution. This quickly led to the development of a network in Austria. Cities like Graz and Linz as well as the Austrian Association of Cities are in constant touch with the WienBot team. The team’s experience is also very much appreciated across national borders: the WienBot creators have been invited to give lectures in Germany, and have maintained an active exchange with the cities of Berlin and Munich as well as the German Ministry of the Interior. The ongoing dialogue also helps to continuously improve the service and incorporate new and fresh ideas.

The strengths of automated communication could thus be fully exploited. WienBot became known for answering questions on restricted opening hours, current guidelines, protective measures or corona aid measures ‘faster than Google’ because the bot provides short, precise answers rather than a list of links. With each new question WienBot learned independently, saving time in the search for the right answer and at the same time relieving the limited resources of public health services and hotlines. As a part of a comprehensive campaign by the City of Vienna, WienBot was placed as an interactive banner in leading Austrian online media such as orf.at (the news website of the Austrian public service broadcaster ORF) and derstandard.at (daily newspaper).

The fully functional widget answered questions on corona, or the current situation in Vienna’s public swimming pools for example. The latter topic was not a random choice because the relevant provisions in the Covid-19 regulations advised people to search online about free capacities before setting out to a public pool. Currently, people submit about 400 000 questions to WienBot every month, with an average 60% of all answers related to the coronavirus or Covid-19. WienBot is available for download as an app (iOS/Android), and is fully integrated into the search function of the service platform wien.gv.at and the City of Vienna app. On the information page about the coronavirus, WienBot has been implemented as a widget. All questions by citizens can thus be answered on the channel of their choice.
