Relevant past paper:
DSE ICT Elec A(SP-2016): PP 4d. 2013 4f. 2015 4c. 2016 4eii.
Questions on data mining focus on application, rather than
the techniques of data mining.
The focus is on:
- Purpose of data mining
- What data you are going to collect
- How you can use the generated information
Purpose
Data mining helps to discover the hidden patterns and trends.
This knowledge allows prediction of future trends and behaviours. An
organisation can use this information to make appropriate decision.
What data to collect
Depending on what you want to know.
For example, if you want to promote sales, you want to
present relevant items to the buyers when they are making purchases on the web.
You may see other products as “Related to items you viewed”. So you may want to
collect data on buying habits and what items are usually bought together in
order to achieve that.
Generated information
With further analysis, you can now group different people
into groups with different behaviours. You can present different products to
the groups based on their behaviours.
