The Path from Data to Actionable Information as a Driver for the Industrial Ecosystem
DATA ENRICHMENT
This stage relates the semantics to the process and use of the equipment . This is where we introduce the intention of the processes , in discrete manufacturing this is done by providing the device constraints , process plans with expected parameters and expected performance . The process constraints allow the analytics to annotate the information stream by comparing the actuals with the expectations and then reporting deviations .
Value is emergent at this stage by using technology such as Complex Event Processing 13 ( CEP ) to recognize patterns . Since we know the meaning of the data , it is possible to place constraints on the data – for example , if the load exceeds a threshold
Enrichment can also make use of existing learning models . Once the semantics are present , it is much easier to build classification systems that provide more tangible value to the users using statistical analysis . Closed loop feedback can also be performed to alter or correct a process before damage or loss occurs .
Enrichment may also introduce additional information models ; these are often static models that describe the expectations for the execution of a process and information relating to the localized process verification 14 . These additional information models allow the analytics at this early stage to gain a larger perspective and make judgments about the outcome and the operation of the equipment .

when a tool is being used to cut a specific type of material , then create an event that indicates something may be going wrong .
