Introduction
• Aims• Problem statement
– Knowledge reusability– Explicit knowledge reuse (ex. Docs)– Tacit knowledge exploitation (ex. Experienced
people’s opinions)
![Page 3: Supporting the learning process through Knowledge Based Systems](https://reader036.vdocuments.mx/reader036/viewer/2022062517/56813259550346895d98e791/html5/thumbnails/3.jpg)
• What is knowledge?Data InformationKnowledge
• Questions to be answered– Where is knowledge located?– How can it be better exploited through
technology means?
• Benefits from Knowledge Based Systems (Skyrme at el., 1997)
• Quick responding to changes• Innovation • Effectiveness

• Famous case studies (Davenport et al., 2001)– Ernst & Young
– Microsoft
– HP
• Activities concerning knowledge reuse– Personalization: Knowledge sharing through person to
person communication
– Codification: Knowledge capture and storage in repositories
– Discovery: Knowledge extraction from databases or the Internet
