摘要:Step One determines the POS (part of speech) of the words in the input sentence. If a word belongs to several POSs, then we record all these POSs in the chart. Step Two constitutes the syntactic structure of the sentence.
d the QUANTS value is the concatenation of the RETREIVED value and the semantic head's QUANTS value;(Case 2) otherwise the RETRIEVED value is empty and the CONTENT value
is token-identical to that of of the semantic head.
The head feature principle and the Subcategorization Principle are defined as
follows.
1 .Head Feature Principle (HFP): The HEAD value of any headed phrase is structure-shared with the head value of the HEAD daughter. (Pollard&Sag, 1994)
2. Subcategorization Principle: In a headed phrase (i.e. a phrasal sign whose DTRS value is of sort head-struc), the SUBCAT value of the head daughter is the concatenation of the phrase's SUBCAT list with the list (in order of increasing obliqueness) of SYNSEM values of the complement daughters. (Pollard&Sag, 1994)
The effect of the HFP is to guarantee that headed phrases really are projections of
their head daughter. And the Subcategorization Principle is to check off the subcategorization requirements of the lexical head as they become satisfied by the complement daughters of its phrasal projections. (Pollard&Sag, 1994)
We now use the following example to explicate the HFP and the Subcategorization Principle. Consider the sentence "She walks." Here the head value of "she" can be abbrievated as NP[nom][3rd, sing]. Here we can use the tag国to represent NP[nom][3rd, sing]. And the head value of "walks" can be abbrieavated as verb[fin]. While the SUBCAT list of "walks" is
, which indicates that the head daughter "walks" needs a complement daughter whose head value should be NP[nom][3rd, sing]. Let us consider in bottom-up fashion, beginning with the lexical head "walks". NP[nom][3rd, sing] is on the SUBCAT list of "walks", therefore, some kind of minus operation is necessary, which means NP[nom][3rd, sing] has to be"checked off' or "cancelled." In other words, another complement daughter like "she"whose head value is NP[nom][3rd, sing] is needed to check off NP[nom][3rd, sing] on the SUBCAT list of "walks" and then "she" is combined with "walks". And thus we obtain "she walks".
The trace principle is defined as follows.The Trace Principle: Every trace must be subcategorized by a substantive head.(Pollard&Sag, 1994)
The task of semantic parsing refers to the derivation of the formal representation,
which is able to reflect the sentence meaning, according to the syntactic structure of the input sentence and the lexical meaning of each lexical entry in the sentence. Theoretically and practically, it is a very important research topic to study what forms
can be used to express sentence meaning. (C. Y Shi, C. N.Huang and J. Q. Wang, 1993,p.423)
For the prospect of semantic parsing, the development of formal semantics provides the basis for semantic parsing. (T. J. Zhao, 2000, pp. 242-245) Originally, the
term "formal semantics" means "the semantic analysis of formal languages". The term
"formal linguistic semantics" is introduced to refer to the part of linguistic semantic structure of human languages. (Lyons,1995) Recently,simple type theory,and linear logic in本论文由英语论文网提供整理,提供论文代写,英语论文代写,代写论文,代写英语论文,代写留学生论文,代写英文论文,留学生论文代写相关核心关键词搜索。
