Keywords

Economic Intelligence, according to (Odumuyiwa V. and David A.,
2010), is a process that involves information collection, processing and
distribution with the goal of reducing uncertainty in decision making

According to (Odumuyiwa, 2011) collaboration is defined as the act
of working jointly with shared objectives
 (Amos David, 1990) defined learning as the activity of acquiring ability
or information
 Education Impact (2001) defined research as a search for knowledge,
a systematic investigation to establish facts
Keywords cont’n…

According to Carlos C. et al (2011) defined a data model as a
relatively simple representation, usually graphical, of more complex
real-world data structures with the purpose of supporting a specific
problem domain

An attribute is a characteristic of an entity

A relationship describes an association among entities.
 Data models use three types of relationships: one-to-many, many-tomany, and one-to-one.

A constraint is a restriction placed on the data
Research Statement of the Problem
There had been many ICT-enabled environment for collaboration projects such as
Living Labs, nanoManipulator, Computer Supported Collaborative Work (CSCW)
and others like Skype and AdobeConnect that found their ways into practical
usage and are even employed for social networking today. While some do not do
remote desktop sharing, some do but do not record the proceedings of the remote
desktop sharing

Discussion

There are three main entities in ICT-BENVCoLeR:
 ACTOR
 ACTIVITY and
 OBJECT
 The central entity is the Actor
 2 Actor Types

For our case study the ACTOR entity is the Actor supertype while PhD student is the Actor subtype
Findings from the modeled data

A model could be deduced for the Actor identity
GMactor= (Attr(general ), Attr(specific), attr∆, Rel (unique), History)
 Where,
 GMactor = ACTOR group model in the collaborative learning and research
environment
 Attr (general )= general attributes common to all the actors
 Attr(specific)= Specific attributes that are unique to one ACTOR type (subtype) or
the other
 attr∆= attributes that change over time
 Rel (unique)= unique relationship for the concerned ACTOR type
 History= tracks of actor’s current and past activities or participation(s)

The derived Topology for the Data Model in ICT-BENVCoLeR
Findings cont’n…

The following knowledge can be derived from the ICT-BENVCoLeR data model:
 WHO? That is, those that managed or participated in certain activities
 WHEN? At what time in the past, did an actor manage certain activities or even
currently.
 WHAT? what activities, in the past or even currently has an actor participated in.
Also, the object(s) that an actor created, in the past or is participating in the
process of creation currently. Furthermore, it could be deduced from this
environment, WHAT versions of a product or object exist and WHAT date were
they created, WHAT theme has an activity and WHAT qualification(s) or
designation(s) changes has an actor overtime.
 HOW? How the role(s), marital status, qualification and designation of an Actor(s)
have changed overtime. How many activities is a particular actor managing?
