10. The method according to claim 7 , wherein each marker is obtained by parsing the first target string and the second target string.
7. A method for perform advanced leveraging for translation, comprising: creating an index structure on a computer by parsing a first target string that comprises a first sentence and a second target string that comprises a second sentence that is different from the first sentence; matching said index structure to index structures previously stored on the computer; and obtaining a translation of the first target string and the second target string, using the computer, corresponding to a match between said index structure and said index structures previously stored on the computer, wherein said index structure comprises phrasal and sub-phrasal markers, each marker having a constituent, a constituent name, and a number that corresponds to numbering each node according to a depth-first visit of the first target string and the second target string, wherein parsing the first target string and the second target string comprises dynamically parsing the first target string and the second target string, wherein in response to the match being determined at a higher sub-phrase level, a lower sub-phrase level of the higher sub-phrase level is not parsed, and wherein the index structure comprises a first phrasal marker corresponding to the first target string and a second phrasal marker corresponding to the second target string.
