How does this approach compare to other Bible dictionaries like Easton, New Bible Dictionary, etc.?
Dictionaries (and HTML representations of them) are made for human readers, and they take advantage of the richness of human language and understanding. However, the richess, subtlety, and imprecision of human language makes it a poor choice for machine processing: for that, far more rigorous specifications are required. The main goal of NTN is provide a machine-processable, reusable information resource.
