Our own classification statistics should improve as more patients have key metabolic lab values (PTH, vitamin D) recorded in the EHR, known to be abnormal early in the course of renal disease [ 74, 75].
Even more specific, in a disease concept corpus, annotation infons where value strings are MeSH concept IDs of the annotated disease strings will have key='MeSH', and infons where value strings are SNOMED CT concept IDs will be paired with key='SNOMED'SNOMED
You create a text file where each line has a key/value pair, separated by a TAB.
Each of these functions has key-value pairs at their inputs and outputs.
Before this research, we had used some popular key/value storage libraries using B-tree and on-disk hash table for building persistent cache storage system for applications.
The reason to perform this aggregation is that although the input key-value pairs have different key values, they may generate the intermediate results with the same key values.
Bigs have made key contribution.
