The invention relates to a method for analyzing a language structure by using a language expression, which is suitable for analyzing structures of more than 7,000 languages on the earth. The method comprises the following steps of: analyzing a morphologic element and a
syntactic structure of a target
sentence by a morphologic element and syntactic analysis unit; and based on a pre-training language expression learning
algorithm provided by a language expression learning
algorithm unit, a language expression calculation unit generates a language expression for the morphologies and syntactic structures of the sentences. Wherein the language expression calculation unit is used for dividing a
sentence into an upper left area, a lower left area, an upper right area and a lower right area by taking a
sentence center symbol as a benchmark, a subject symbol is distributed in the upper left area, a core
verb symbol is distributed in the lower left area, and a
verb type symbol is distributed in the lower right area; non-predicate symbols representing remaining phrases other than subjects and verbs are assigned to the right upper region. Furthermore, symbolization specific information including marks (1-4) indicating a person and a character number mark (.) indicating the number of word characters such as nouns and adjectives is added to at least one of the left upper mark, the left lower mark, the right upper mark and the right lower mark of each symbol. By means of the method, the sentences in the specific language can be accurately analyzed into structured syntactic expressions, and therefore the efficiency of language
processing such as
sentence recognition, semantic understanding, translation and retrieval is improved.
