Creating a knowledge base means integrating multiple data sources and assigning these data with a meaning (an ontology). This is what linked data are about.
A knowledge base allows any size company to convert data into smart data and extract value from them by asking questions, creating services or applications, and selling data.

The open data available on the web are growing exponentially and they represent an incredible opportunity for any company to enrich and grow their knowledge base. However, scouting the open data cloud is not easy and locating the useful datasets can be tricky.  To facilitate this research, a number of services that provide lists of open data sites are available. Here you are some examples:

  • this is the go-to resource for US government-related data. It claims to have up to 400,000 data sets, both raw and geospatial data, in multiple formats. 
  • European Data Portal: similar to the US portal, but related to European 28+ countries. 
  • Google Public data explorer: it hosts data about the world development indicators, the OECD and the human development indicators.
Once you found the data sets with the information you were looking for, LinkedData.Center can help you to integrate them in your knowledge base, providing a structured approach to solve data overlaps, and guaranteeing the data quality by keeping track of the source.

Ready? Go!
Three simple steps are necessary for the knowledge base setting up with LinkedData.Center 

  1. select the data sources
  2. express your trust  for the used data
  3. define what you want to know
