ABSTRACT:
The invention relates to methods and devices for binary coding and decoding by similarities for structured documents After having decomposed the data to code into a series of symbols, each item of data being at least partially represented by a symbol, and having selected at least one item of data to code, a search is carried out for a first sequence of symbols coded beforehand, identical to a second sequence of symbols to code, comprising a symbol representing a part of said data. Similarly, a search is carried out for a third sequence of symbols coded beforehand of which one symbol is distinct from the symbol corresponding to a fourth sequence of symbols to code comprising said symbol representing said part of said data. In response to the comparison of their coding efficiency, the second or the fourth sequence is coded.
