How Merge sort connects Entity context

The extracted context around Merge sort shows recurring relationship patterns in the source. For example, Merge sort → Bing-Chao Huang, Geffert, Katajainen, Kronrod, Langston, Many, Michael, One, Plugging, Several, STL, SymMerge, Though Another extracted example is Merge sort → Although, Arrays, In Java, Merge, Perl, Quicksorts, RAM-based, The Linux. Use these groups to spot repeated connection types before inspecting the individual relationships.
