The extraction of process models from text refers to the problem of turning the information contained in an unstructured textual process descriptions into a formal representation,i.e.,a process model. Several automated approaches have been proposed to tackle this problem, but they are highly heterogeneous in scope and underlying …

The extraction process typically involves separating the solution into two distinct phases: an aqueous phase and an organic phase. During this process, impurities remain in the aqueous phase while the lithium ions move into the organic phase. To isolate the lithium, the organic phase is treated to separate out the lithium ions, which are then ...

For example, the process of extracting the chemical Artemisinin that is used for the treatment of malaria worldwide is typically done with an extraction process. It is a complicated process that involves a volatile chemical (ether can explode if you are not careful) that is heated so that it can percolate out the compound.
