Challenges Encountered (1/2)• Establishing the Business Case: Set out goals and establish

what data needs to be linked

• Data Discovery and Provenance: Appropriate internal and external data need to be searched for and discovered (Quality problems, etc)

• Information Extraction and Data Harvesting: Not all the data will be useful. Relevant data items need to be extracted

Challenges Encountered (2/2)

• Data Cleaning: Most of these datasets, internal and external, will not be in the format that can be made use of. Need to be cleaned

• Data Interlinking: The Choice of Join Points. What do you use to do the inter-linking?

• Data Modeling

• Data Management: Some data need to be brought in at run-time, or cached and made available when needed. Therefore, policies to manage the live and cached data sets need to be devised

Future Work• Future Work includes • System Trials• Adding more internal BT data• Ingesting more external data
