Figure 2.5 Ontological structure in OntoWise
OntoWise facilitates access to project information and automatic sharing of
project information in the following ways:
Automated notification: When information is uploaded onto OntoWise, the system
checks the profiles of other users in the project team. If the information matches
a user's profile sufficiently strongly, a notification (SMS or email) can be
automatically generated and sent to the user concerned, informing the user
of the discovery of the information. Thus, in cases where a user's profile indicates
that they would have a strong interest in a particular type of information, they are
immediately and proactively informed about the availability of this information.
Searching and accessing information: Users (mobile workers) can supply a query in
the form of a set of key words and phrases in the way familiar from WWW
search engines. The application then retrieves the most closely matching draw-
ings/documents held in the project database and displays a ranked list of links to
the pages retrieved and their abridgements. The scores of each retrieved page and
any annotation made by the original author are also shown.
Personalized information: A user can also ask the application to display documents/
drawings that are of high priority to the user. The system then interrogates the
project database and retrieves the most recently stored information. It deter-
mines which of these best match the user's profile. The user is then presented
with a list of links to the most recently uploaded information, along with a
summary, annotations where provided and date of storage, the sharer and an
indication of how well the information matches the user's profile.
