ARISTOTELE Approach: overview

1. To merge strategicorganisational objectives andworker preferences and needs

to create personalised andadaptive learning experience;

2. To support organisationalprocesses: optimising humanresource allocation; supportingdaily work through PersonalWorking Learning Environment;individual performanceassessment;

3. To support innovationmanagement and buildingthrough Innovation Factory

The top level is the starting point: inputs (organizational objectives and workerneeds, preferences, ) influencing the key ARISTOTELE processes

The middle level embraces the key ARISTOTELE processes centred on

collaboration: Building of personalized learning experiences

Creation of Innovation Factory for collaborative innovation boosting

Management and sharing of personal knowledge to be reused in different domains and tasks

The bottom level includes features supporting update and reuse of organizationalknowledge

ARISTOTELE enabling building blocks

and research areas

The general Idea

6


7/31

Knowledge Model (KM)

provides constructs for the representation ofenterprise knowledge entities, enterprise

domain vocabulary, educational vocabulary Competence Model (CM)

provides constructs for the representation ofcompetences and their relations to otherconcepts such as context, activities, and

objectives

Worker Model (WM)

provides constructs for the representation ofworker including social, learning, workingand personal goals

Learning Experience Model (LEM)

provides constructs for the learningexperience needed to achieve a newcompetence or fill a competence gap.

ARISTOTELE Models



8/31

The models have been defined following four maindirections:

the analysis of organizational practices of the pilots, theprojects scenarios and requirements, and the methodologiesneeds to derive the main concepts and relationships of the fourmodels;

the definition of few and clear principles to follow during themodeling activities;

the selection of a set of specifications, standards and availablemodels from the the State-of-the-Art and Intelligent Web

Teacher (IWT) platform that represent the building blocks of thefour models;

the analysis of actual experiences from communities of practice

Role of the Models: Integrated Schemas

Reference Ontologies: used to represent andstructure enterprises resources (e.g., worker profile,

competences, project and activities, etc.) FOAF, DOAP, SKOS, SIOC, etc.

Organisation Ontologies: exploited to provide a

shared classification of the resources available in theKnowledge base.

to classify knowledge resources according to the context of theenterprise and to provide a common access layer toheterogeneous resources daily produced by the workers (e.g.,document, wiki, blog, etc.).

Knowledge Management (KM) Tool, exploiting methodologiesand techniques supporting organizational knowledge building andmaintenance (merging, matching, versioning) in a semi-automatic

way using knowledge extraction techniques as well. Human Resource Management (HRM) Tool, exploitingmethodologies and techniques supporting competence gapanalysis, team and group formation, internal resourcescompetence development, and recruitment.

Social Collaboration and Networking (CN) Tool, aiming atsupporting the innovation process within the organization. . Learning Experience Generation (LEG) Tool, exploiting

methodologies and techniques to recommend suitable contentsand didactic approaches to the workers, to generate, adapt andmanage personalized learning experiences tailored to theorganizational objectives.

Personal and reliable Working and Learning Environment(PWLE) tool, acting as a methodological and technologicalintegrator for all the other tools.

The Tools

How Fit Everithing Together

20/31

Several Challenges Complexity of the systems

Enterprise architecture

Enterprise Application Integration and Semantic technologies Integration of Several Technologies

several form of deployment (SaaS, IaaS, distributed, centralised)

Facilitate Adoption, Acceptance and Assimilation

Provide the right information to the involved stakeholders

(distributed teams) Respecting the time constrains

Key decisions Incremental approach (2 steps)

first High Level Architecture (guidelines, approach description anddocumentation) exploited for tools design

Architecture Design leveraging on existing frameworks

Design the ARISTOTELE Architecture



21/31

Provides a methodological and technological framework describing

principles and guidelines underlying the whole ARISTOTELE

Platform

Provides specification of the logical description of the architecture Provide an understanding of what kind of building block we rely on and

How theycontribute to the achievementof the whole system

Provides guidelines for architects and developers team in charge

of the design and development of the differentARISTOTELE

modules

Provides information about decomposition of the platform Identification of the main building blocks

Identification of their responsibilities

Provides information about ARISTOTELE enabling technologies

features

Definition of the High Level Architecture

What it is: Sketch the whole system



22/31

Definition of the High Level Architecture

Documentation (1/2)

Produce the documentation that communicates thearchitectural decisions

Inspired to the Views and Beyond (V&B) approachproposed by the Software Engineering Institute Motivation An architecture document is useful only if it

communicates effectively the architectural decisions

Fundamental unit of documentation Views, each representinga "part of the whole" system structures

Fundamental principle Documenting an architecture is amatter of documenting the relevant views, and then adding

documentation that applies to more than one view

The concept of View allows simplify the communication byfocusing only on some aspects at a time
