Here you may start with a root term or text to discover other concepts by their TechNet relations through an interactive and iterative graph search. Clicking a term in the graph may discover the term most relevant to it in TechNet. Continually clicking the same term N times will discover its next N most relevant terms, and generate a local star graph of N branches. This represents a width-oriented search. Alternatively, clicking a leaf term may discover another new leaf term. Continually clicking on the new leaf term and doing so N times will generate a chain of N terms. This represents a depth-oriented search. The interative graph search allows both exploitation of local concepts around the root and exploration of distant concepts from the root. Please note that the tree visualization here only shows the term discovery trajectories not all relations among the terms, whereas TechNet is an almost fully connected graph instead of a tree.
