ARISTOTELE Project
 Personalized Learning & Collaborative Working
Environments Fostering Social Creativity and Innovations
Inside the Organizations
 Integrated Project (IP) co-funded by the European
Commission FP7
 Theme ICT-2009.4.2, Technology Enhanced Learning,
Grant Agreement no. 257886
 8 partners from 4 European countries
 4 Academics
 2 Industrials
 2 Pilots
3

ARISTOTELE Project
 Objectives
 To develop models, methodologies, technologies and tools to
support the development of competencies and
creativity by self-organizing, acquiring, processing and
sharing of information and knowledge inside the enterprise
 To support the day-by-day activities of the knowledge
workers (Reinhardt et al. 2011)
 Target
 Medium-large “knowledge-intensive” enterprise
4

ARISTOTELE Platform
 A designed and integrated set of online services that
provide workers, managers and trainers with tools and
resources to support and enhance the emergence of
their competences and creativity
5

Overview of the platform
 Information Space
 structured and un-structured data (i.e.
Web pages, databases, documents,
etc.)
 Semantics
 Services
 Business logic, Data access
 Composable
 Tools
 Interface for the final users
 Composable
 External application integration
6

Building blocks
7

Tools
 Tools build up the presentation layer
 provide a set of conceptually-related functionalities
in order to help worker activities.
8

Personal Working and Learning
Environment (PWLE)
 Purpose
 assisting the knowledge worker in his/her daily working
activities, by acting as a methodological and
technological integrator for most of the other tools
 supports learning and knowledge activities, connects
workers with each other, and contributes to the
organizational knowledge
9

Learning Experience Generation(LEG)
 Purpose
 provides workers with suitable contents and didactic
approaches
 generates, adapts and manages personalized learning
experiences tailored to the organizational objectives.
10

Human Resource Management (HRM)
 Purpose
 supporting competence gap analysis
 supporting team and group formation
 supporting competence development for internal
resources, and recruitment
11

Social Collaboration and Networking (CN)
 Purpose
 exploits methodologies and techniques to combine
adaptive learning strategies with non-adaptive
emergent competence change, based on serendipitous
exploitation of other people's knowledge made
available in social networks
12

Knowledge Management (KM)
 Purpose
 providing a set of tools a set of tools which support
organizational knowledge building and maintenance
(merging, matching, versioning) in a (semi)automatic
way
13

Services
 Architecture design inspired by SOA principles
 Standardized interface (platform independent)
 Loose Coupling
 Discoverability
 Composability
 Abstraction
 Reusability
14

Services
 Base Services
 User Authentication
 User Profile Services
 Business Connectivity Services
15

Core Services
 Knowledge Management System Service
 Knowledge Extraction
 Knowledge Building
16

Core Services
 Linked Data Layer (LDL)
 enables data access for tools and other services
 provides the aggregation of information distributed
over heterogeneous sources
17

Core Services
 Recommender System
 provides information filtering in order to recommend
information items that are likely to be of interest to ta worker.
18

Core Services
 Social Networking
 provides information filtering in order to recommend
information items that are likely to be of interest to ta worker.
19

Data
 Heterogeneous information
 RDBMS
 Sharepoint contents
 RDF/OWL repositories
 3 «kinds» of data
 Content Data
 Semantic Data
 Business Data
20

Business Data
 Data managed by the tools are built by merging
information from content and semantic data into
classes
 these sets of classes are called Business Entities
 A Business Entity has the role of decoupling the
communication and the management of data at a
business level from the nature of the actual data
sources.

Models for Knowledge-Intensive
Enterprises
 Four semantic models representing
 the knowledge domains
 the personal worker’s competences and profiles
(including knowledge, skill, attitudes, and preferences)
 the enterprise knowledge including objectives and skills
(concerning learning and businesses activities)
 the context and the didactical approaches
26

Enterprises
 Well-known semantic technologies integration
27

Enterprises
 Knowledge Model
 Knowledge concerning enterprise assets
 strategies, processes, activities, documentation, and, in
general, all the output generated by workers
 Knowledge concerning organization-specific information
 lightweight ontologies meant to provide a shared
classification of the organization's resources and entities
 Knowledge concerning training
 Representation of the educational domain that may be
exploited by a company
28

Enterprises
 Competence Model
 Competence descriptions in terms of Knowledge, Skills
and Attitudes (KSA)
 competences of a worker and the evidence of their
acquisition
 competences needed to fulfill a particular role/job (job
description)
29

Enterprises
 Worker Model
 representation of workers inside their organization,
including
 personal information
 social activities and relationships
 learning preferences and needs
 Working activities and involvements
30

Enterprises
 Learning Experience Model
 provides a representation of the elements required to
support the generation of personalized learning
experiences
31

Conclusion
 Conceptual Models for representing semantic
information in the enterprise
 Implementation of a semantic platform for enterprise
management (tool & services)
 Architecture based on SOA principles
 Linked Data Layer to manage the knowledge thus
represented and make it accessible by both the
internal components and external tools
 TODO
 Experimentation
