Abstract
Methods and apparatus implementing systems and techniques for differencing token streams and detecting moved blocks of tokens. In general, in one implementation, the technique includes: obtaining a first token stream and a second token stream, comparing the first and second token streams to identify a group of tokens that are substantially similar in the first and second token streams, the similar-tokens group including common sub-sequences, which are identical in the first and second token streams, and at least one unmatched token, and presenting matched token information corresponding to the similar-tokens group to represent changes in document flow.
