This study attempted to analyze Reverse Polish Notations of ambiguous sentences exemplified by Noam Chomsky in his 'Syntactic Structure' with particular intention of comparison of their variables dependently of the meanings. The methodology for the analysis was based on the junction theory from Junction Grammar developed by Dr. Eldon G. Lytle, Professor of Brigham Young University. For the purpose of this paper, only structural ambiguity was dealt for the reason that the others did not make any differences in reverse polish notation.
Subjunction rules applied for this paper were divided into two types: homogeneous sub junctions and heterogeneous ones. Symbolically the former was giver as:
1. X* X/D?X or X_(1)*X_(2)/D?X, which was antecedent-oriented, while the latter was given as
2. X* Y/D?X, which was topic-oriented.
This paper also tied to summarize the funcitons of Reverse Polish Notations, and to classify the types of factors of linguistic ambiguity as well as to compare the Reverse Polish Notations by analyzing ambiguous sentences in English for providing the better foundation for automatic language processing.
This paper concluded that lexical ambiguity and phonological did not make any differences in Reverse Polish Notations, and should be dealt on the contextual level for disambiguations in analysis of input languages and synthesis of output languages in order to match the meanings of these languages.
