        <p>This paper explores the challenges of web redesign in Public Administration (PA), particularly within universities. Universities often struggle with fragmented online presences due to distributed editorial models and diverse communication needs across research, education, and dissemination activities. Limited resources further restrict investment in upskilling staf and adopting modern technologies. Open source solutions, though cost-efective, are often chosen without considering user experience. We present a methodology that combines user-centered design, Artificial Intelligence (AI), and ”radical collaboration” to achieve a future-proof and scalable redesign. Starting from a case study of a major web redesign project at an Italian university (2014-2020) involving hundreds of websites and over 200 content editors, the paper details the process, including a large-scale content audit using AI, single sourcing with AI-powered content transformation, and user experience (UX) testing with data visualization. This approach resulted in a unified, user-centric online presence and garnered recognition, including the ForumPA award for best innovator. The paper concludes by discussing the applicability of this methodology to other PA institutions facing similar challenges.</p>

            ture The statistical analysis of the existing website
starts by considering the website as a directed network of
documents (nodes) connected through hyperlinks (edges).
One example is represented in Figure 1, where the main
structure of the studenti.unige.it (mid-2017) is depicted.
By exploiting network analytics [
            <xref ref-type="bibr" rid="ref9">9</xref>
            ], we explored the
distributions of the in-degree and out-degree, that are the
number of in-coming links, and the number of out-going
links, respectively. We argue that the scale-free
property, that characterizes the World-Wide-Web as a whole
[
            <xref ref-type="bibr" rid="ref10">10</xref>
            ], is no longer evident for specific sub-categories of
websites. Particularly, we defined a method that could
be used to better characterize topological properties
deriving from diferent generative principles: central or
peripheral. The first category is typically characterized
by a strong central control in the design and evolution
of the IA and content generation. Conversely, the last

information overload, and new digital technologies that large
organizations face [

            ]. The system highlights the
importance of human-centered design throughout the content
management process. It is designed to be user-friendly
and easy to learn, even for non-technical users. This
ensures that content creators can focus on creating
highquality content, rather than struggling with the

website and tightly control the structure or a multitude
of contributors that are allowed to write based on
collaborative editing and community moderation. The result
on the UniGe website denoted a combination of central
and peripheral editorial strategies that, over time, led to a
chaotic arrangement, confirming the need for a profound
redesign.

            Architecture We then proceeded by defining an
AIdriven approach to define the optimal IA. Specifically,
we exploited topic modeling methods [
            <xref ref-type="bibr" rid="ref12 ref13">12, 13</xref>
            ] to identify
how many topics were discussed on the website and
visualize how the pages often presented multiple unrelated
topics, leading to a confusing UX. The result of such an
experiment on studenti.unige.it is visualized in Figure 3,
where the fuschia squares represent the topics and the
blue dots represent the pages. Even at first glance, it is
clear that many pages are linked by two or more topics,
with a central cluster of pages connected to up to 5 topics.

          <p>To assess the overall usability of the newly designed
website and the efectiveness of the entire procedure, we
resorted to a set of UX tests conducted on a sample of 60
students divided into two groups (  = 22.7   ), with
the purpose of comparing the usability of the corsi.unige.it
website, designed with the methods above, and of
studenti.unige.it, which historically UniGe uses to
communicate with its students. Each user must answer three
questions related to a course of study, navigating
exclusively on one of the two sites. The questions were the

Our successful experience in UniGe resonated across
several national outlets and was presented in several news
channels and conferences [
            <xref ref-type="bibr" rid="ref14 ref16">14, 16</xref>
            ] and culminated in
winning the ForumPA award for best innovator [
            <xref ref-type="bibr" rid="ref17">17</xref>
            ]. The
exposure we received from these initiatives allowed us to
get in touch with other realities that were facing similar
issues as the ones we faced in UniGe. In this line, we
were able to begin a tight-knit collaboration with the
Department of Design at Politecnico di Milano (PoliMi),
where the Design PhD Programme at PoliMi was facing
the problem of redesigning their website. The PhD
Programme in Design at PoliMi is the largest PhD design
course in Italy, with almost 90 PhD students enrolled.
          </p>
          <p>Their goal was to devise a system that could allow for
an optimal presentation of the research activity carried
on by the PhD alumni and candidates as well as a website
that could describe procedures to potential new students
(admission procedure, courses requirements, etc.) and
stakeholders. Our involvement since the very beginning
of the redesign process, allowed us to adopt the
methodology defined for UniGe. Together, we identified the major
pain points from their old websites, mainly consisting
of a lack of automation, an inactive homepage, and a
content strategy that did not leverage single-sourcing,
user profiling, or structured information. The result was
a set of websites that penalized the research eforts.
Applying our methodology allowed us to identify the root
of these ineficiencies. In particular, PhD procedures lack
a connection between the legacy data, processes and the
website content. Also, in research dissemination pages,
the existing data structure does not account for the
interactions among researchers and therefore it is dificult to
keep up-to-date and coherent. Currently, the project is
focusing on designing a data-driven system which may
enhance the usability of the websites through refining the
quality of the underlying information structure. A
primary objective is to establish an architecture capable of
robust automation. This architecture aims to convert
natural language and simple information about researchers’
activity in structured data. By exploiting legacy data in a
seamless flux, the system reduces maintenance efort at
the bare minimum and keeps data in sync and up to date.</p>
          <p>Also, the system will behave by considering research as
the result of heterogeneous networks of people and
topics. In doing so, the data produced by the research eforts
become structured and easily reusable across diferent
touchpoints.</p>

      <title>5. Discussion and Conclusion</title>
      <p>Our experience with two large scale universities,
suggests that Italian academia still lacks concrete strategies
and methods to tackle the ever increasing amount of
information a PA faces today. Particularly in the
context of web redesign, we defined a methodology that
goes beyond a shallow visual redesign in favor of a new
methodology where existing data is first used to guide
the definition of an optimal IA and then structured to
feed the touchpoints based on single-sourcing,
interoperability, and user profiled approach. Our methodology
exploits design thinking principles, User-Centred Design
methods, agile programming, prototyping and
innovators (young fearless developers and designers) to define
a new way of thinking about information and how to
distribute it across complex organizations. The result is a
system that is able to govern a multitude of diferent and
interconnected websites thanks to AI, Natural Language
Processing and data management principles.</p>
      <p>Academia represents a unique type of PA, tasked with
the crucial responsibility of not only accumulating vast
knowledge but also efectively sharing it with the broader
public. However, like many PAs, academia tends to
exhibit a conservative stance toward digital advancements,
often resisting change and clinging to outdated methods.
Rather than embracing true innovation, there’s a
tendency to equate progress with simply digitizing existing
processes. This approach typically prioritizes documents
over recognizing the central importance of data, which
should serve as the foundation for all operations,
particularly within sprawling institutions characterized by
numerous interconnected yet autonomous departments.</p>
