        <p>Knowledge management allows managing not only the information possessed by people but also the experiences, judgments, and cognitive beliefs adapted and empowered by an individual's mind. There are five views of knowledge management: people, organizational aspects, process, measurement and knowledge representation, and technologies. This paper proposes a Scoping Study based on the following research questions: how many papers are associated with knowledge representation and technologies? which representation techniques and technologies are presented in the papers? and what categories of them are possibly identified in the papers? In the review, 1107 papers were found, on which exclusion criteria were applied and 61 articles were found for detailed analysis. The analysis allows identifying the following categories for the knowledge representation and technologies view: socialization techniques, techniques or models for knowledge explanation and representation, fields of study, logical and analytical processes, organizational practices, and technological tools.</p>

        <title>2.1. Data, Information, and Knowledge</title>
        <p>
          Diferent visions about data and information are presented in [
          <xref ref-type="bibr" rid="ref1">1</xref>
          ], which shows that data "has
been defined as a symbol that has not yet been interpreted according to Spek and Spijkervet, a
simple observation of the state of the world according to Davenport or as a raw, simple and
discrete fact as stated by Bhatt, Beveren, Davenport and Prusak, and Herder and others". In the
same work, information is understood by Davenport and Prusak and Nonaka and Takeuchi
as a set of messages; while for Bollinger and Smith, it is processed data, organized according
to Bhatt or with meaning according to Spek and Spijkervet. For Rios Ortega [
          <xref ref-type="bibr" rid="ref2">2</xref>
          ], information
"means data aggregation, organization, or classification with meaning, (and) implies some kind
of processing or understanding." Information can be defined as a function of data [
          <xref ref-type="bibr" rid="ref3">3</xref>
          ], to contain
both the data and its context, as specified in the following equation:
  =  () =  + 
(1)
        </p>
        <p>Where f (Data) is a function with the input “data”, that gives meaning to these data and
returns Information.</p>
        <p>
          The knowledge, from a constructivist approach, is part of a hierarchy, called DIKW proposed
by Ackof [
          <xref ref-type="bibr" rid="ref4">4</xref>
          ] constituted by data at the lowest level, information at the next level, and knowledge
in the third level of the hierarchy; finally, wisdom constitutes the upper level. For Díaz and Millán
[
          <xref ref-type="bibr" rid="ref5">5</xref>
          ], knowledge is defined as "the mixture of cognitive and contextualized beliefs, perspectives,
judgments, methodologies, information, experiences, and expectations made about an object,
which are adapted and potentiated by the mind of an individual (knower)". For Li [
          <xref ref-type="bibr" rid="ref3">3</xref>
          ] the
knowledge equation is:
 = ( ) =   +  + ℎ
(2)
        </p>
        <p>Where p (Information) denotes the processing function that returns knowledge by making
sense of information under its context. The term "insight" represents the tacit implications.</p>

        <title>2.2. Knowledge Management</title>
        <p>
          Knowledge management (KM) is a theoretical notion attributed to Etzioni Amitai and defined as
"how to create and use knowledge without undermining the organization" [
          <xref ref-type="bibr" rid="ref6">6</xref>
          ]. It is an integrated
ifeld of multiple disciplines that allow the development of initiatives at diferent levels of the
company [
          <xref ref-type="bibr" rid="ref7">7</xref>
          ], with a multidisciplinary approach aimed at a comprehensive and systematic view
of information assets [
          <xref ref-type="bibr" rid="ref8">8</xref>
          ]. Perez Gonzalez and Darín [
          <xref ref-type="bibr" rid="ref9">9</xref>
          ] defines it as "an agglutinating process of
information management, technology and human resources whose execution is focused on the
improvement of high-impact processes, the optimization of knowledge based on these processes
and their dissemination throughout the organization". For Bueno [
          <xref ref-type="bibr" rid="ref10">10</xref>
          ], Knowledge Management
is a process through which organizations manage to discover, use and maintain knowledge,
with the idea of aligning it with business strategies to obtain competitive advantages.
        </p>
      </sec>
      <sec id="sec-2-3">
        <title>2.3. Views of Knowledge Management</title>
        <p>
          A view describes the concepts, elements, and characteristics of an integrated knowledge
management system from the perspective of a set of related concerns. There are five views: people
(role, responsibilities, etc.), organizational aspects (including structure and culture), process
(and his activities), measurement and knowledge representation, and technologies [
          <xref ref-type="bibr" rid="ref11 ref12">11, 12</xref>
          ].
This work is related to the last view. Some authors consider technology and representation as
diferent views, many do not consider the representation, and others use the terms in a similar
or indistinct way, therefore the proposal of [
          <xref ref-type="bibr" rid="ref12">12</xref>
          ] to consider them as a single view is followed,
which will be used throughout this work.

        <title>2.4. Representation and Technological View</title>
        <p>
          For [
          <xref ref-type="bibr" rid="ref13">13</xref>
          ], the technological view, called "Information and Communication Technologies (ICT)"
involves the means to collect, store and distribute data, information, and explicit and tacit
knowledge; alignment with the organization’s strategy and needs, especially those required
when studying the other components.
        </p>
        <p>
          Servin [
          <xref ref-type="bibr" rid="ref14">14</xref>
          ] says, about the technological view, that "a common misconception is that
knowledge management is mainly about technology (. . . ) Technology is often a crucial enabler of
knowledge management (and) it can help connect people with information, and people with each
other, but it is not the solution. And it is vital that any technology used ’fits’ the organization’s
people and processes – otherwise it will simply not be used".
        </p>
        <p>
          Omran [
          <xref ref-type="bibr" rid="ref15">15</xref>
          ] calls "hard aspects" the introduction and use of diferent key information
technologies for knowledge management activities. In particular, he proposes some technologies: data
mining, data warehousing, and groupware, among others, and presents the TAM (Technology
Acceptance Model) proposed by Davis.
        </p>
        <p>
          The notion of knowledge representation, in many cases, is associated with Artificial
Intelligence and some works of Ronald Brachman. But it is a term used in several fields of knowledge.
Several observations on the term can be found in [
          <xref ref-type="bibr" rid="ref16">16</xref>
          ] says that the knowledge representation
model "is a particular way of representing knowledge by using the knowledge and reasoning
mechanism" and [
          <xref ref-type="bibr" rid="ref17">17</xref>
          ] which says that the knowledge "must be represented in a way that allows
information systems to actively process knowledge, rather than only to represent it, and thus to
enable knowledge-based reasoning". For the SUNY Center [
          <xref ref-type="bibr" rid="ref18">18</xref>
          ], the knowledge representation is
"structures used to store knowledge in a manner that relates items of knowledge to one another,
and that permits an inference engine to manipulate the knowledge and its relationships."

      <title>3. Method</title>
      <p>This article presents a Scoping Study. This section presents the method used and the data
analysis.</p>
      <sec id="sec-3-1">
        <title>3.1. Scoping Study</title>
        <p>This work proposes a Scoping Study, also known as a Systematic Mapping Study, which is a
type of Literature Review. While the Systematic Literature Review makes it possible identity,
evaluate and interpret all available research relevant to a particular research question, topic
area, or phenomenon of interest, the Systematic Mapping Studies are designed to provide a
wide overview of a research area. Their main diferences are the depth of the study and the
rigorous application of the method and definition of inclusion and exclusion criteria.</p>
        <p>
          Scoping studies "aim to map rapidly the key concepts underpinning a research area and the
main sources and types of evidence available and can be undertaken as standalone projects in
their own right, especially where an area is complex or has not been reviewed comprehensively
before" [
          <xref ref-type="bibr" rid="ref19">19</xref>
          ]. It is possible to identify at least four common reasons why a scoping study might
be undertaken: to examine the extent, range, and nature of research activity; to determine the
value of undertaking a full systematic review; to summarize and disseminate research findings
and to identify research gaps in the existing literature [
          <xref ref-type="bibr" rid="ref19">19</xref>
          ].
        </p>
        <p>
          Arksey and O’Malley [
          <xref ref-type="bibr" rid="ref20">20</xref>
          ] propose the following method for scoping study: identifying the
research question; identifying relevant studies; study selection; charting the data; and collating,
summarising, and reporting the results. The phase of study selection is important because the
initial outcome examination from the search protocol may pick up several irrelevant studies
[
          <xref ref-type="bibr" rid="ref20">20</xref>
          ] [
          <xref ref-type="bibr" rid="ref21">21</xref>
          ]. This is related to the importance of defining terminology at the beginning of a
scoping study, and sometimes reflects some specific dificulties, such as the use of terminology
in diferent countries or diferent contexts. The phase of charting describes a technique for
synthesizing and interpreting qualitative data [
          <xref ref-type="bibr" rid="ref21">21</xref>
          ].

        <p>
          For the analysis of the results obtained in the review presented in the previous section, an
analysis with open coding is carried out, based on the systemic design for the qualitative
research [
          <xref ref-type="bibr" rid="ref22">22</xref>
          ] and the procedures of Strauss and Corbin [

          ].
        </p>
        <p>
          In the open coding, "all the segments of the material obtained for analysis are reviewed and it
generates -by constant comparison- initial categories of meaning. It thus eliminates redundancy
and develops evidence for the categories (raises the level of abstraction)" [
          <xref ref-type="bibr" rid="ref23">23</xref>
          ]. The categories
are created from an interpretation of the data [

      <p>
        This section considers the papers obtained and presented in section 4.3. and the technologies or
representation elements presented in 4.4. For the analysis of the results obtained in the review,
an analysis with open coding is presented: by reviewing the data obtained and available and
their interpretation, categories of analysis are proposed in this section 5. In section 6 all the
elements found are analyzed, using these categories, and identifying each proposed element.
Through a review of the data obtained and available and their interpretation, categories of
analysis are proposed:
• Socialization techniques: socialization techniques are those that allow the exchange
of experiences and the transfer and acquisition of tacit knowledge. For this category,
technological tools that could facilitate these techniques are excluded and only techniques
and mechanisms are included.
• Techniques or models for knowledge explanation and representation: these are the ways
and techniques to make knowledge explicit in some support or model, including those
probable models. Each technique or model is likely to be supported by some technological
tool, but these tools are not included in this category.
• Field of study: refers to a branch of knowledge or a set of branches of knowledge with
interdisciplinary action. Each field encompasses a set of processes, technologies, etc.
• Logical and Analytical Process: corresponds to data and information processing and
treatment activities. It may include technological tools but especially involves analysis
and exploitation processes.
• Organizational practices: following to [
        <xref ref-type="bibr" rid="ref26">26</xref>
        ], this category represents "mechanisms used
by an organization to communicate its values, norms, and goals to its employees and is
instrumental".
• Technological tools: corresponds to artifacts that are able to be deployed in a technological
infrastructure environment, including the software, part of the software, or similar
[
        <xref ref-type="bibr" rid="ref27 ref28 ref29">27, 28, 29</xref>
        ]. In general, these tools can model as components in a sequence diagram
or deploy a diagram of Unified Modeling Language.

    <sec id="sec-6">
      <title>6. Analysis into each category</title>
      <p>For each category, a detailed description of the technological and representational elements
most frequently found in the works is presented, using references from the articles found in
this study.</p>
      <sec id="sec-6-1">
        <title>6.1. Socialization techniques</title>
        <p>Socialization techniques are those that allow the exchange of experiences and the transfer and
acquisition of tacit knowledge. For this category, technological tools that could facilitate these
techniques are excluded and only techniques and mechanisms are included.</p>
        <p>The socialization techniques found were Community of practices, Cofee knowledge,
Discussion groups, Brainstorming, Mentoring, and Expert assistance. The number of findings is
presented in Table 2.</p>
        <p>
          The term most found included in the socialization techniques category has been “community
of practice”, which refers to "a group of people united by one or several skills in common,
periodically and stably over time, able to learn and share their experiences in this common
practice" [
          <xref ref-type="bibr" rid="ref30 ref31">30, 31</xref>
          ]. These groups have regular interaction, although he also considers that their
formation may be spontaneous (unintentional).
        </p>
        <p>
          The discussion groups and the cofee knowledge imply less stability and do not require
common practices; a cofee knowledge "is a group discussion to reflect and share thoughts and
insights in a friendly way (...) It leads to deeper insights and more intense sharing than usual"
[
          <xref ref-type="bibr" rid="ref32">32</xref>
          ]. Brainstorming can be applied in any of the communities or groups mentioned above.
        </p>
        <p>
          Wenger [
          <xref ref-type="bibr" rid="ref31">31</xref>
          ] also proposes to consider the assistance of colleagues, a technique used by
project teams to request assistance from colleagues and specialists on an important situation,
whose objective is to obtain knowledge before an activity through a meeting with invited
colleagues and specialists; the project team receives insights from its colleagues at meetings.
Another proposal for the participation of experts in knowledge management is mentoring
through which an expert accompanies a worker, shapes people’s competencies, observes and
analyzes performance, and provides feedback on the execution of activities.

        <p>In this category are included the ways and techniques to make knowledge explicit in some
support or model, including those probable models. Each technique or model is likely to be
supported by technological tools, but these tools are not included in this category.</p>
        <p>The techniques or models for knowledge explanation and representation found are best
practices, case studies, catalogs, directories, frequently asked questions (FAQ), genetic
algorithms, knowledge maps, lessons learned, metadata, newsletters, neural networks, ontologies,
organizational memory, process map, the quality record for practices, standards and procedures,
storytelling, taxonomies, wiki, and yellow pages. The number of nfidings is presented in Table
3.</p>
        <p>The details of the most frequently mentioned techniques, as listed in the table above, are
presented below. Since many techniques were found, only the most frequently mentioned are
selected for detailed analysis.</p>
        <p>The knowledge maps allow the identification of assets and sources of tacit or explicit
knowledge but do not contain them. It is useful for the localization, and evaluation of capacities,
opportunities, needs, and knowledge restrictions. It is a visual representation of resources and
lfows of knowledge of the organization.</p>

          Good practices are rules or actions that in an organization have given results of improvements
in actions or processes and that are conducive to or influence the achievement of objectives,
productivity, and competitiveness [
          <xref ref-type="bibr" rid="ref33">33</xref>
          ]. Organizational memory is "organizational knowledge
that integrates past experiences, archived and lived in the context of the organizations" [
          <xref ref-type="bibr" rid="ref34">34</xref>
          ].
For [
          <xref ref-type="bibr" rid="ref35">35</xref>
          ] "from the structure of organizational memory is that school organizations understand
their internal reality, being able to help in decision making based on good or bad practices." [

        <p>
          A wiki allows share knowledge freely by the workers in an organization, allowing the creation
of a knowledge spiral with the accumulation of diferent contributions over time. Rivero [
          <xref ref-type="bibr" rid="ref40">40</xref>
          ]
states that wikis "serve for collaboration between workers sporadically and simultaneously,
users can update the wiki if they are working collaboratively and have the power to edit a page
dynamically".

          Several works, among them, [

      <title>7. Conclusions</title>
      <p>This paper presents a Scoping Study based on the following research questions: how many
papers are associated with knowledge management technologies? which technologies are
presented in the papers? and what categories of technologies are possibly identified in the
papers?</p>
      <p>The search returned 1107 papers (without considering the exclusion criteria). The reading of
the works found allows the identification of those that consider aspects of the technological
and representational view; there are 61 papers that consider this view.</p>
      <p>Then, analysis and categorization of each of the elements of technology and knowledge
representation found are carried out through the open coding technique. The analysis allows
identifying the following categories for the knowledge representation and technologies view:
socialization techniques, techniques or models for knowledge explanation and representation,
ifelds of study, logical and analytical processes, organizational practices, and technological
tools. And finally, the diferent technological tools are grouped according to the following
subcategories: type of systems, repositories and storage media, bidirectional communication
tools, tools for content presentation, and others.</p>
      <p>The results of this work allow for ordering the diferent technologies and knowledge
representations, categorizing them, and helping to the construction of a technological architecture of
an integral knowledge management system.</p>
