Abstract: The use of Artificial Intelligence (AI) in the public sector is on the rise. Yet, there is no
clear definition of AI. While AI is considered to be useful for process optimizing and efficiency,
there are also concerns for its impact on citizens, for example regarding transparency and
discrimination. For this reason it is important to understand how and for which purpose AI is
being used within government. Few explorative studies have provided fragmented insight into
how AI is used in the public sector, but a clear overview of typical applications is still lacking. To
support insight into public sector use of AI, this paper develops a typology for applications of
public sector AI. This typology is based on a literature review. Based on the literature, we find
eight types of applications of public sector AI. In further research, we will validate this typology
with evidence from practice.
Keywords: AI, Public Sector AI, Artificial Intelligence, Typology, AI challenges

Relations of the Netherlands.
1. Introduction
The use of AI in the public sector has increased in the past years. The European Commission defines
AI as: “Artificial intelligence (AI) refers to systems that display intelligent behavior by analyzing
their environment and taking actions – with some degree of autonomy – to achieve specific goals.”
(European Commission, 2018, p. 1). As such, AI may improve public sector performance, by making
processes more efficient, thereby reducing costs, and by improving the quality of services (Chui et
al, 2018; De Sousa et al, 2019; Misuraca, van Noordt & Boukli, 2020). However the use of AI also
raises some concerns; depending on how it is used, it can help or damage people (Feijoo & Kwon,
2020). For example, AI systems can be used for profiling, which if used in the wrong way could lead
to discrimination (Thierer, O'Sullivan & Russell, 2017; Wirtz, Weyerer & Geyer, 2019; Feijoo & Kwon,
2020).

122 Ongoing Research
To improve our understanding on the opportunities and challenges of public sector AI, it is
important to first understand how and for which purposes AI systems are used within government.
A few studies have provided explorative and fragmented insight into how AI is used in the public
sector (Misuraca, Van Noordt & Boukli, 2020; Van Veenstra, Grommé & Djafari, 2020). However, a
structured overview of how and for which purposes AI is used in the public sector is still lacking (
Kankanhalli, Charalabidis & Mellouli, 2019; Misuraca, Van Noordt & Boukli, 2020). To gain such an
overview, it is useful to have a typology that focuses on typical applications of public sector AI.
Individual case studies have provided us with fragmented evidence of specific types of use of public
sector AI (Androutsopoulou et al, 2019; Sun & Medaglia, 2019). Furthermore, many typologies of
public sector AI often have a technological focus (e.g. Wirtz, Weyerer & Geyer, 2019; Misuraca, Van
Noordt & Boukli, 2020). Therefore, the objective of this study is to develop a typology for public
sector AI applications based on literature, that will support the understanding of how and for which
purposes is AI technology applied.
To develop such a typology, the following method is applied: a study of the literature is
conducted and then a typology based on literature is introduced. The paper is structured as follows.
First the state of the literature on AI in the public sector is discussed. Subsequently an overview of
current typologies on AI in the public sector is used to develop a typology based on literature. The
paper concludes with a discussion of the findings.
2. Public Sector AI
While AI is not a new phenomenon, it has, as a result of a large increase in computing power gained
much attention over the last years (Kankanhalli, Charalabidis & Mellouli, 2019; Misuraca, Van
Noordt & Boukli, 2020). However, there is no generally accepted definition of AI (yet). Based on four
often used definitions from the European Commission (2018), OECD (2019), the High-Level Expert
Group on AI (AI HLEG) (2019) and the Dutch Strategic Action Plan for AI (SAPAI) (2019) we
discerned four common elements. The first element is that AI systems are either software or
hardware systems that are designed by humans (European Commission, 2018; High-Level Expert
Group on Artificial Intelligence, 2019). The second element is that data is processed for specific and
complex purposes. The third element is that AI systems can operate with varying levels of autonomy
(OECD, 2019; Dutch Ministry of Economic Affairs and Climate, 2019). And the fourth element is that
AI either uses symbolic rules or numeric models for prediction, recommendations or automated
decisions (High-Level Expert Group on Artificial Intelligence, 2019). From a technological
perspective, AI is considered an umbrella term that includes many different types of technologies
such as predictive analytics, natural language processing (NLP), speech analytics, robotics and
image recognition techniques (Fong, 2018; Berryhill et al., 2019).
Misuraca, Van Noordt & Boukli (2020) found that within the public sector the use of AI
applications is emerging, based on a landscape analysis of the use of AI in European countries. They
found 85 different examples of AI applications in government across fifteen European member
states. Van Veenstra, Grommé & Djafari (2020) performed a mapping exercise of public sector data
analytics in the Netherlands, including examples of AI. While they identified 74 examples of public
sector data analytics, they were not able to determine how many of them make use of AI. However,
Ongoing Research 123
beyond these exploratory mapping exercises not much is known yet about how and for which
purposes AI is used to improve public services and government operations (Misuraca, Van Noordt
& Boukli, 2020). There are however a couple of case studies that aimed to give an insight into the
use of specific AI technologies in the public sector. For example, with the use of NLP, machine
learning and data mining technologies, Androutsopoulou et al. (2019) developed a chatbot that can
foster communication between citizens and government.
There is a lot of research on challenges regarding the application of AI in the public sector.
Technical and data challenges are insufficient size of available data, a lack of standards for data
collection, the data and system quality and data security (Androutsopoulou et al., 2019; Sun &
Medaglia, 2019; Wirtz, Weyerer & Geyer, 2019; Campion et al., 2020). Organizational challenges are
a lack of skills and expertise in public organizations, financial feasibility, a lack of collaborative
culture and a resistance to sharing data between parties (Wirtz, Weyerer & Geyer, 2019; Campion et
al., 2020). However, these challenges are not new. Similar challenges have also been identified in the
context of the use of public sector data analytics (Van Veenstra, Grommé & Djafari, 2020). Ethical
and societal challenges that are often attributed more specifically to AI-based algorithms are
transparency and explainability, since the autonomous nature of many AI algorithms means that
these algorithms may function as a ‘black-box’, which means that the outcomes of these algorithms
may be difficult to explain (Janssen & Kuk, 2016; Craglia et al., 2018). AI can also create bias, which
may result in discrimination; the use of AI therefore risks hampering human rights and public values
like human dignity, equal treatment and privacy (Craglia et al., 2018). Since there is no generally
accepted definition of AI and we are still trying to understand for which purposes public sector AI
is used, we do not know when and in which phase specific challenges can arise. For this reason,
there is a need for a typology that takes into account both the purpose of an application and the type
of AI technology that is used.
3. A Typology for Public Sector AI Based on Literature
To develop a typology for public sector AI, a literature search was undertaken. First, a Scopus search
using the search terms "AI" AND "Government", "AI" AND "Public sector", was conducted.
Subsequently, the snowball method was used, in which the key documents found through the
Scopus search were used as a starting point for finding other literature. In addition, two expert
researchers were asked to give suggestions on known typologies. Many of the challenges regarding
the use of public sector AI are identical to the challenges encountered with the use of public sector
data analytics. Therefore typologies based on data analytics are included within the scope of this
study.
The literature search identified nine papers presenting typologies. These were subsequently
reviewed and compared. We included both typologies with a focus on the use of big data analytics
in the public sector (Mehr, 2017; Poel, Meyer & Schroeder, 2018; Santiso & Roseth, 2018; Van Ooijen,
Ubaldi & Welby, 2019; Van Veenstra, Grommé & Djafari, 2020) and typologies with a focus on the
use of AI in the public sector (Chui et al, 2018; De Sousa et al, 2019; Wirtz, Weyerer & Geyer, 2019;
Misuraca, Van Noordt & Boukli, 2020). Among the nine papers with typologies, a distinction can be
made between those that focus on the technical applications of data analytics and AI, and those
124 Ongoing Research
applications that address a type of governmental process. Furthermore, some of the typologies are
developed based on literature only, while others are also validated by empirical research.
Four of the examined typologies focus on the technical applications of data analytics and AI
(Mehr, 2017; Chui et al, 2018; Wirtz, Weyerer & Geyer, 2019; Misuraca, Van Noordt & Boukli, 2020).
For example Wirtz, Weyerer & Geyer (2019) provided a list of ten technical applications of AI in the
public sector, varying from virtual agents to cognitive robotics & autonomous systems. For each of
these technical applications they provide examples of public sector use cases found in the literature.
For example, predictive analytics can be used for prediction of water levels or crime prediction and
virtual agents can be used for the application of chatbots. Mehr (2017) on the other hand, identified
six problems where AI techniques can provide a solution for, including resource allocation, shortage
of experts, working in large data sets, procedural and repetitive tasks, scenario prediction and
diverse data. Whereas Chui et al. (2018) identified three categories where AI can help to improve
performance: predictive maintenance, logistics optimization and personalization. All these
typologies look at how AI techniques can help governments, but they do not take into account the
specific role that a governmental organization may have (Van Veenstra, Grommé & Djafari, 2020).
Five studies have identified types of applications that are aimed at improving governmental
processes and policymaking (Poel, Meyer & Schroeder, 2018; Santiso & Roseth, 2018; Van Ooijen,
Ubaldi & Welby, 2019; De Sousa et al., 2019; Van Veenstra, Grommé & Djafari, 2020). Santiso &
Roseth (2018) and Van Ooijen, Ubaldi & Welby (2019) distinguish four different stages of data
analytics: descriptive analytics, diagnostic analytics, predictive analytics and prescriptive analytics.
Based on other studies in the literature, De Sousa et al. (2019) developed an overview of 22 AI
solutions for the public sector, ranging from knowledge management and data processing
automation, detecting fraud, measurement and optimization of public transport to crime prediction
and assessment.
Five studies that were found have been based on literature research, or have mentioned
individual examples of applications of public sector AI (Mehr, 2017; Santiso & Roseth, 2018; Van
Ooijen, Ubaldi & Welby, 2019; De Sousa et al., 2019; Wirtz, Weyerer & Geyer, 2019). Some papers
have gone a step further and also based their typologies on an empirical mapping of examples of
usage in practice (Chui et al., 2018; Poel, Meyer & Schroeder, 2018; Misuraca, Van Noordt & Boukli,
2020; Van Veenstra, Grommé & Djafari, 2020). Poel, Meyer & Schroeder (2018), Van Veenstra,
Grommé & Djafari (2020) and Misuraca, Van Noordt & Boukli (2020) developed their typologies by
undertaking such mapping studies. After conducting a policy analysis and interviews with
stakeholders, Poel, Meyer & Schroeder (2018) identified different phases in the policy making
process like foresight and agenda setting, monitoring and interim evaluation, problem analysis,
identification and design of policy options, policy implementation and ex-post evaluation and
impact assessment, of which most of the examples were in the foresight and agenda setting phase.
Misuraca, Van Noordt & Boukli (2020) conducted a preliminary mapping exercise across the EU
where they aimed to gain a better understanding of current AI implementations in the public sector.
Their typology focuses on the type of AI techniques that are applied in practice, including image
recognition, natural language processing, pattern recognition, robotic process automation and
robotics.
Ongoing Research 125
Based on a mapping study on the usage of data analytics in the Dutch public sector, Van Veenstra,
Grommé & Djafari (2020) formulated a typology for the use and purpose of public sector data
analytics, including AI. Six types of purposes have been identified, including personalization,
resource allocation, maintenance, inspection and enforcement, crime investigation and forecasting.
Based on the typologies discussed above we have further developed Van Veenstra, Grommé &
Djafari (2020)’s typology on the use of public sector data analytics in the Netherlands and specifically
tailored it to the use of AI in the public sector. Because this typology combines technical aspects of
data analytics with government roles and has been developed based on an empirical study of 74
applications, we use this typology as a starting point. Subsequently, we attune this typology based
on literature on the other typologies specifically to AI.
Table 1 presents the results of this exercise. To attune the typology of Van Veenstra, Grommé &
Djafari (2020) to public sector AI, we investigated the typologies found in the literature in relation
to the categories of the framework. Based on the literature, we found that two categories were
missing. Therefore, to give a more complete overview of the type of use of AI in the public sector,
based on the study of Poel, Meyer & Schroeder (2018) on the use of big data for policy analysis and
the study of De Sousa et al. (2019) and Wirtz, Weyerer & Geyer (2019) on AI applications for
knowledge management, we added the categories ‘knowledge management’ and ‘policy analysis’.

4. Findings and Discussion
The objective of this study was to develop a typology for public sector AI based on literature, that
supports the understanding of how and for which purposes is AI technology applied. Based on the
literature we find that a typology based on eight categories is useful to map the use of public sector
AI. These eight categories of public sector AI illustrate for which purpose AI can be used within
government: ‘tailored solutions’, ‘process optimization’, ‘maintenance’, ‘inspection and
enforcement’, ‘crime investigation’, ‘knowledge management’, ‘forecasting’ and ‘policy analysis’.
This typology of eight categories addresses three main challenges with public sector AI. The first
challenge is that there currently is no clear definition of AI. AI is considered an umbrella term for
different technologies that can be used for different purposes. The second challenge is that there are
no definite mapping studies available. There are few exploratory mapping studies available, such
as Van Veenstra, Grommé & Djafari (2020) and Misuraca, Van Noordt & Boukli (2020). However,
these studies do not give a complete overview of how public sector AI is used in practice. In addition,
a third challenge is that we do not know which type of AI can be linked to certain challenges, as it is
unclear which challenges are associated with which phases.
Currently, there is a lot of effort to understand, define and map public sector AI. This typology
may support this research, and may help to categorize challenges. In addition, a more complete
overview can be given of when and for which purposes a certain AI technology can be used. For
example, in this study we found that chatbots and virtual agents are often used for tailored solutions
aimed at personalizing public service to individual needs of citizens, whereas forecasting and the
prediction of trends and scenario's use predictive analytics. This typology has not yet been validated
with evidence from practice. We aim to validate this typology with evidence from practice in the
next phase of our research.
5. Conclusion
This study developed a typology for applications of public sector AI based on literature. Such a
typology can be used not only to gain a structured overview of public sector AI, but also to gain
insight into which type of applications are associated with certain challenges. Based on a literature
Ongoing Research 127
study of nine typologies of public sector data analytics and AI we identified eight categories of
public sector AI: ‘tailored solutions’, ‘process optimization’, ‘maintenance’, ‘inspection and
enforcement’, ‘crime investigation’, ‘knowledge management’, ‘forecasting’ and ‘policy analysis’. A
limitation of this study is that it is solely based on other typologies mentioned in the literature.
Therefore, we do not know if this typology is representative in practice. For this reason, we aim to
validate this typology in practice in further research.
