Objectives of research

• To design and implement a transformation tool
• To design and implement the components of an ITS
• To create a rich, face-to-face learning
  interaction through the use of a pedagogical
  agent
• To integrate all of the above components to form
  IMSTD
• To evaluate students and educators attitudes
  towards this ITS

Proposed research work

• Step 1 Read natural language input text into
  IMSTD
• Step 2 Part of speech tagging using Brills
  tagger

Proposed research work
11
Proposed research work

• Step 3 Classifying and removing redundancies and
  plurals

12
Proposed research work

• Step 4 Apply heuristics
• Step 5 Refer to history

13
Proposed research work

• Step 6 Produce preliminary model

14
Proposed research work

• Step 7 Human intervention
• Step 8 Produce final model
• Step 9 Incorporate into ITS

Contribution to the knowledge

• A new technique to transform a natural language
  database specification into an ER model
• The formation of new heuristics

18
Conclusion

• Questionnaire results support the evidence that
  Data Modelling is difficult
• Proposed project will contribute to knowledge
• Worked examples show that the project is
  achievable within the time period
