摘要
[目的/意义]针对我国汉藏双语用户在网络信息搜寻中的语码转换现象,对汉藏双语查询式的构造进行研究,为汉藏双语用户和搜索引擎提供语码转换搜索场景下的搜索策略与检索系统优化建议。[方法/过程]采用受控用户实验的方法,采集语码转换情境下汉藏双语用户的查询式,对双语查询式集进行文本分析、聚类分析,获取汉藏语码转换情境下的查询式构造特征,归纳查询重构模式。[结果/结论]对比汉-藏与藏-汉语码转换方向,发现用户在语码转换前后的查询式长度、语法复杂度与语义相似度上均体现出明显的差异。汉藏双语语码转换的查询重构表现出偏离、邻近、扩展与简缩4种模式。
[Purpose/Significance]In order to study the code-switching phenomenon of Chinese-Tibetan bilingual users in online information search in China,the paper studies the patterns of Chinese-Tibetan bilingual query formulation,and provides suggestions for optimizing search strategies and retrieval systems in code-switching search scenarios for Chinese-Tibetan bilingual users and search engine.[Method/Process]A controlled user experiment was used to collect the query patterns of Chinese-Tibetan bilingual users in the code-switching context.Text analysis and cluster analysis on bilingual queries were conducted to obtain the query formulation characteristics of in the Chinese-Tibetan code-switching context and to summarize the query reformulation schemas.[Result/Conclusion]Comparing the directions of Chinese-Tibetan and Tibetan-Chinese code-switching,it is found that users show significant differences in query length,syntactic complexity and semantic similarity before and after code-switching.In the query reformulation of Chinese-Tibetan bilingual code-switching,four schemas of deviation,proximity,expansion and abbreviation are demonstrated.
