Embodiment Construction

[0026] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention will be further explained below in conjunction with specific embodiments.

[0027] The present invention includes the following steps:

[0028] a) Distinguish between single and multiple sentences: divide long sentences into several short sentences;

[0029] b) Semantic role tags: case tags, including grammatical role components, nominalized or non-predicated verb block tags, except for non-annotated content;

[0030] According to the needs of case marking and semantic role marking in Tibetan, the semantic role of Tibetan is clarified. The core semantic role is Arg0-5, Arg0 represents the agent of the action (action case), Arg1 represents the effect of the action (result case), Arg2-5 has different semantic meanings according to different predicate verbs, adding some additional semantic roles , Such as ArGM-LOC (personality).

Abstract

The invention relates to a method of processing minority characters into Chinese language, and in particular relates to a united labeling method for syntax of Tibet language and semantic roles. The united labeling method comprises the following steps of: a) distinguishing a simple sentence and a compound sentence; b) labeling semantic roles; c) recognizing a predicate; d) classifying verb semantics; e) labeling a syntactic structure; f) editing and revising semantic role labeling results. According to the united labeling method, the syntax of Tibet language and semantic features are extracted, on the one hand, semantic role information such as a performer, a receiver, time, a place and a way expressed in the sentence can be labeled by directly utilizing grammatical labels of the Tibet language; on the other hand, a syntax analytical process can be reacted upon by the predicate semantic role labeling result so that the influence of the syntax labeling which is not well-determined can be reduced, and accordingly the performance of a sentence processing system can be improved.

Description

Technical field [0001] The invention relates to a method for processing ethnic minority characters into Chinese, in particular to a method for joint labeling of Tibetan syntax and semantic roles. Background technique [0002] The research content in the field of Tibetan information processing has blossomed, and breakthroughs have been made in word, word and phrase processing, and the research on the sentence processing stage has begun. [0003] Semantic analysis is one of the most challenging subjects in the field of computational linguistics, and it is also the main bottleneck restricting the large-scale application of language information technology. Semantic analysis is to deduce the actual semantics of the sentence based on the sentence structure and the meaning of the actual words in the sentence. This is the main goal of sentence processing. [0004] The task of semantic role labeling is to find out the corresponding semantic role components of the predicate in a sentence, suc...
