Abstract

The invention discloses a corpus searching method and system, and belongs to the technical field of corpus searching. The method comprises the following steps: constructing a searching syntax tree according to a searching condition and a construction rule; and traversing syntax trees in a corpus according to a level priority so as to search nodes matched with the searching syntax tree, and outputting a searching result. The system comprises a corpus database and a client, wherein the client is provided with an input module, a construction module, a traversing module, a searching module and an output module. According to the corpus searching method and system, the searching conditions of users can be described through a syntax tree form, and nonlinear traversing is carried out along the syntax trees of the corpus, so that the structural characteristics of the syntax trees of the corpus are fully utilized, the scanning frequency of the whole corpus is greatly reduced and the searching speed is effectively improved.

Description

technical field [0001] The invention relates to the technical field of corpus retrieval, in particular to a corpus retrieval method and system. Background technique [0002] A corpus is a collection of electronic texts collected in a sampled fashion, usually for the study of a language or variants of a language. For data-driven language or language variant research, in addition to the corpus, software tools are also needed to analyze and mine the content of the corpus. Software tools play a vital role in the development and application of the corpus. The current corpus processing tools include: WordSmith, MonoConcPro, Conordance, and online corpus SketchEngine, etc. The main functions of these tools include: vocabulary usage and syntax retrieval, automatic vocabulary annotation, manual annotation auxiliary tools, text organization, statistical analysis, etc. [0003] The most commonly used functions in corpus research are lexical usage and syntactic retrieval. The core of ...
