Questions We Asked• How to manage and extract value from these
disparate, isolated data, and• How to take advantage of information from
external, non-enterprise, and social media to provide new, exciting, and useful services that create value for BT customers

Linking Social, Open, and Enterprise Data
• Social Data: LinkedIn• Open Data: OpenCorporates• Enterprise Data: BT’s internal SalesForce data
and HR data

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
![Page 18: Linking Social, Open, and Enterprise Data](https://reader035.vdocument.in/reader035/viewer/2022062305/56816562550346895dd7e794/html5/thumbnails/18.jpg)
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
