... Processing Type A and Type B Chains. For type A chains, we construct range reporting data structure, as described in Fact 1, with each chain (i, j), j = next(i), mapped to a weighted two dimensional point (j, depth(i, j)) with weight doc(i). Likewise, for type B chains, we map chain (i, j) to the po ...

B-tree
In computer science, a B-tree is a tree data structure that keeps data sorted and allows searches, sequential access, insertions, and deletions in logarithmic time. The B-tree is a generalization of a binary search tree in that a node can have more than two children (Comer 1979, p. 123). Unlike self-balancing binary search trees, the B-tree is optimized for systems that read and write large blocks of data. B-trees are a good example of a data structure for external memory. It is commonly used in databases and filesystems.
