and the number of new things listed on the menu. This tool is closely related to the count dictionary, but it is limited to listing the number of times a selectable element occurs in a large corpus of data. "A simple natural language coder," as Gowda termed it, is "a computer program for the creation of thesaurus entries," or, as he explained, "a means to transform that sentence into a list of triples (subject, predicate, object)."- Christopher Bartlett, "Substance over Structure: Simple Programs That Make Language Practical," In Boden, ed., Proceedings of ICALP, 1999, 1,10795.
In econometrics, if you are dealing with new data, you need to know whether to use your previously built model or to build a new one using the new data-that is, to reestimate standard parameters or to get new estimates of the standard parameters.
