This post deals with some aspects of local grammar graph (LGG), a sequence recognizer and extraction tool. Local Grammar is developed by Maurice Gross to capture and describe a linguistic phenomena.
Some LGGs Advantageous over Regular Expression
Question. Is it the only tool? There exists another tool which is called regular expression. Many computer scientists are familiar to this term. However, there are some advantageous of LGG over regular expression. First, LGG is supported by graphic interface. It's user friendly. For someone like me who does not know much programming, it is proven to be very helpful. Check this illustration out to see how LGG looks

LGG with Output

Second, with LGG, you can give output. So here is the order. You recognize, extract, and after that give output. An example above shows you an LGG that is equipped with output. In the example, output is designed to give decription of every extracted lexicons. You can also have translation for each lexicon as long as your dictionary supports it
