      <abstract>
        <p>European small and medium-size enterprises (SMEs) and large corporations face multiple constraints to engage in trade abroad and to localize their products and services to other countries, mainly as a consequence of legal and language barriers. This is one of the main consequences of the multiple differences across Europe, which is fragmented into legal silos and into more than 20 linguistic islands. LYNX H2020 project will provide more effective ways of accessing huge amount of digital regulatory compliance documents, including legislation, case law, standards, industry norms and best practices. In particular, the LYNX project envisages an ecosystem of smart cloud services to better manage compliance documents, based on a Legal Knowledge Graph (LKG) which integrates and links heterogeneous compliance data sources. This ecosystem will enable smart search, smart assistance and smart referencing of case law, as well as Artificial Intelligence technologies and machine translation of regulatory compliance documents. An initial step in the development of the LYNX platform is the collection of business requirements from end-users and relevant stakeholders. Therefore, this work introduces the techniques used for the gathering of business requirements from endusers and stakeholders and a list of prioritized business requirements collected through qualitative and quantitative techniques.</p>

      <title>1. Introduction</title>
      <p>The European market is fragmented into legal silos and into more than 20 linguistic
islands, which constitutes a competitive disadvantage for SMEs and companies in
general. Therefore, dealing with legal and regulatory compliance data is a cumbersome
task usually delegated to law and consultancy firms, who have to obtain documents from
several data sources, published by various institutions according to different criteria and
formats by various institutions.</p>
      <p>The main objective of LYNX is to create an ecosystem of smart cloud services to
better manage compliance, based on a legal knowledge graph (LKG) which integrates
and links heterogeneous compliance data sources including legislation, case law,
standards and other aspects. This cloud of services integrated in the Lynx platform will

provide mass-customized regulatory information (including legislation, regulations, and
policies) to European businesses.</p>
      <p>The aim of this work is to collect all the business requirements provided by
endusers and relevant stakeholders (SMEs, Large Enterprises, Law firms, among others).
Quantitative and qualitative techniques have been used in order to gather and prioritize
each of the business requirements identified.</p>
      <p>This work is structured as follows: Section 2 lists some legal and business
requirements for compliance works and European projects and briefs Legal Compliance
by Design (LCbD) and Legal Compliance through Design concepts (LCtD); Section 3
describes the process used for the elicitation of the business requirements; and finally,
Section 4 points out the results obtained from the Knowledge acquisition process carried
out in the previous Section.</p>

      <title>2. Legal Compliance</title>
      <p>
        Legal and business requirements for compliance (especially for compliance by design)
have attracted much attention [
        <xref ref-type="bibr" rid="ref1">1</xref>
        ]. Previous EU projects—especially COMPAS 2 ,
OPENLAWS3, EU Cases, MIREL4, and BO-ECLI—have developed conceptual toolkits.
Moreover, the Workshop on Requirements Engineering and Law (RELAW)5, has been
running from ten years now, led by specialized researchers such as Sepideh Ghanavati
and Guido Boella.
      </p>
      <p>
        In a previous edition of the LYNX Workshop on Legal and Regulatory Compliance
(TERECOM), we presented some preliminary results from the survey we are carrying
out [
        <xref ref-type="bibr" rid="ref2">2</xref>
        ], after examining 280 works on Compliance by Design in the past fifteen years.
After examination of the state of the art, we suggested the concept of Legal Compliance
through Design (LCtD) to complement LCbD by recognizing the role of social, political,
and economic conditions (as pre-conditions) and governance and ethical requirements
(as constraints) when designing legal compliance, encompassing norms and principles
that require a balancing of competing rights, obligations or policies. Conditions for legal
compliance are broader and more entangled than for regulatory compliance, as legal
conditions can be described by means of rules, but rules alone do not play out the
stakeholders’ rights, duties, and legal effects of their behavior.
      </p>
      <p>We focused on the definition of legal (not only documentary) sources to select and
define requirements. Compliance through Design (CtD) explicitly encompasses the
social and institutional aspects that are not explicitly included by the regular way of
approaching this subject (i.e. legal interpretation processes —beyond the conversations
between experts and computer scientists—, institutionalization, the interface between
modelling and coordination, and the relation between citizens, consumers, and the law).</p>
      <p>
        This is coherent with Motta’s assertion about the interdisciplinarity of descriptive
empirical approaches [
        <xref ref-type="bibr" rid="ref3">3</xref>
        ], and with the need to consider software requirements as
prescriptive statements.

        <p>Thus, the results summarized in Table 2 and Table 3 could be reframed into a general
classification of legal sources, properties, and entity relations, respecting the autonomy
and decision-making capacity of lawyers, rulers, administrators, companies,
businessholders, and lay-people. This is compatible with the LYNX approach as well.</p>

      <title>3. Knowledge Acquisition Process</title>
      <p>The Knowledge Acquisition Process (KAP) performed—following the Value
Proposition Canvas6—consists of quantitative (survey) and qualitative (interviews and
focus groups) techniques. These techniques are applied to relevant end-users and
stakeholders outside the LYNX project use cases. The profiles of these relevant
endusers and stakeholders are listed in Section 3.1.</p>
      <p>The KAP is specifically devised to provide the LYNX consortium with the outmost
business requirements in three different subjects when dealing with digital regulatory
compliance documents:
• Strategy for the search, analysis, processing, monitoring and handling of
digital regulatory compliance documents. It includes workflows and/or
strategies for the analysis, process and management of digital regulatory
compliant documents.
• Pains when dealing with digital regulatory compliant documents. This
subject is focused on collecting anything that could annoy
customers/entities before, during and after dealing with digital regulatory
compliant documents.
• Gains when dealing with digital regulatory compliant documents. This
subject is focused on collecting outcomes and benefits from
customers/entities when dealing with the analysis, processing and
managing of regulatory compliant documents.</p>
      <p>Therefore, Section 3.1 defines the role, description and requirements of the
endusers and stakeholders for their participation in the KAP phase; Section 3.2 describes
the quantitative (survey) stage performed within the KAP; and in Section 3.3
introduces the qualitative (interviews and focus groups) stage of the KAP process
designed for the LYNX project.</p>
      <sec id="sec-3-1">
        <title>3.1. Targeted end-users and stakeholders</title>
        <p>The end-users and stakeholders targeted for the knowledge acquisition process (surveys,
interviews and focus groups) are described in Table 1. In this table the description and
requirements are listed. The list of requirements is not exhaustive; any institution with
relevant knowledge or know-how for the LYNX project is suitable to participate in this
phase.</p>

        <title>3.2. Survey</title>
        <p>The LYNX survey design process relies on two main pillars: (i) the identification of
relevant end-users and stakeholders and the requirements that make them suitable for the
LYNX scenario (Table 1); and (ii) the Value Proposition Canvas for the design of the
questionnaire.</p>
        <p>The Value Proposition Canvas helps to design products and services that end-users
and stakeholders really want because it allows to focus on what matters most to them.
Jobs to be done by end-users and stakeholders is one of the main inputs since jobs
describe the things that end-users and stakeholders are trying to get done in their work
or in their life. A job could be the tasks they are trying to perform and complete, the
problems they are trying to solve, or the needs they are trying to satisfy.</p>
        <p>What are the stepping-stones? What are the contexts? How do the activities change
depending on these contexts? What functional problems are end-users and stakeholders
trying to solve? These are some of the questions involved in the Value Proposition
Canvas. As a result, Figure 1 depicts the survey design scheme developed for the LYNX
survey.</p>
        <p>
          The final questionnaire obtained from the survey design process is published in [
          <xref ref-type="bibr" rid="ref4">4</xref>
          ].
It also contains the Electronic Consent; the organization profiles; the strategy for the
search, analysis, processing, monitoring and handling of digital regulatory compliance
documents; pains and gains. A total of 120 e-mails were sent out with invitations to
answer the questionnaire. As a result, 15 of the contacted organizations answered the
survey. The distribution by country and organization profile is listed in [
          <xref ref-type="bibr" rid="ref4">4</xref>
          ].

        <title>3.3. Interviews and Focus Groups</title>
        <p>
          A “Qualitative Interview” is a method of collecting rich and detailed information about
how individuals experience, understand and explain certain events or particular topics
[
          <xref ref-type="bibr" rid="ref5">5</xref>
          ]–[
          <xref ref-type="bibr" rid="ref8">8</xref>
          ]. Interviews are “semi-structured” because the interviewer has a list of questions
or key points to be covered during the interview and works through them in a methodical
manner. Similar questions are asked to each interviewee, although supplementary
questions could be asked as appropriate. In general, questions are worded so that
responses are open-ended.
        </p>
        <p>This open-endedness allows the participants to contribute with much detailed
information as they desire; it also allows the interviewer to ask probing questions as a
means of following-up. In other words, the interviewees could in principle respond how
they like. This can make quite difficult for the interviewer to keep the interviewee on
focus while interviewing, and then extract similar themes or codes from the interview
transcripts. However, semi-structured interviews reduce individual biases within the
study, particularly when the interviewing process involves many participants.</p>
        <p>However, this perspective about the risks of qualitative research may lead to a
reductionist view that we would like to avoid. Qualitative methods have been described
at length in Knowledge Acquisition Processes (KAP) for modelling. Enrico Motta edited
a special issue on 25 years of KAP in the Semantic Web area at International Journal of
Human-Computer Studies. Elaborating on Gaines, Gruber and Bradshaw’s contributions,
he wrote [3, page 132]: “ [...] much of the interesting action concerning knowledge
technologies was actually taking place in the semi-secluded gatherings of this small
community and that the real interesting issues were not the formal and abstract
Knowledge Representation problems, tackled through ‘‘dryerase whiteboard results’’
(Gruber, this issue), but the ones concerning the effective development of symbiotic
intelligent systems (Bradshaw, this issue; Gaines, this issue). These issues could only be
tackled effectively through an interdisciplinary approach, grounded as much into
empirical investigations and cognitive science principles, as in formal knowledge
representation and computational architectures. “</p>
        <p>We could not agree more. A genuine non-eclectic interdisciplinarity orientation is
key to tackle LYNX problems on building a Knowledge Legal Graph, and to map legal
and business requirements.</p>
        <p>Hence, we adopted a two-fold strategy: (i) encompassing this empirical approach to
properly eliciting modelling requirements across several business and legal fields (as a
process); (ii) combining quantitative and qualitative methods in the structured formal
line advanced, e.g. by the Unified Modeling Language (UML) perspective (as an
outcome). In this sense, completeness, consistency, adequacy, unambiguity,
measurability, pertinence, feasibility, comprehensibility, good structuring, modifiability,
and traceability will be deemed quality factors to define the goals of the Requirement
Engineering process [9, page 35 and ff]. “The requirements emerging from the elicitation
and evaluation phases of the RE process must be organized in a coherent structure and
specified precisely to form the requirements document “(ibid. 174).</p>
        <p>Qualitative research can specify and introduce useful nuances to the summary of
preliminary survey results. The interview and focus group techniques based on further
elaboration of the previous questionnaire leaded to interesting results, allowing end-users
to refine some of the answers already obtained. First, revealing some internal
organizational processes and strategies of government agencies, small / large companies,
and law-firms which had not been detected by the survey. Second, providing illuminating
expressions and language that summarize the end-user’s conceptual perspective,
concerns, and needs on compliance and regulatory problems.</p>
        <p>
          During this phase, 5 interviews and 1 focus group were conducted by researchers within
the project. Detailed results for this phase is published in [
