Lexical Graph Construction Based On The Tibetan Epigraphic Corpu

The inscriptions of the Tubo period provide rich historical information and cultural connotations.However,difficulties such as their scattered distribution,age,and destruction have made their study challenging.This article constructs an ontology knowledge base consisting of 27 inscriptions from the Tubo period and conducts vocabulary quantification analysis and research on the Tibetan grammatical category based on this knowledge base.This work has important practical significance and social value for promoting the study of Tibetan history,culture,language,and script,as well as for the digitization and popularization of cultural heritage.Research content of this article.Introduction summarizes and concludes the research at three levels: research objects,corpus research,and semantic web technology,and explains the value of constructing a vocabulary map.Chapter 1 sets the goal of constructing a knowledge base for the ontology of inscriptions,and first divides the material into linguistic segmentation,transcription,and annotation to form a uniformly formatted parallel corpus.Then,knowledge classification coding and tagging are performed on the corpus,and the ontology data format is converted.Chapter 2 extracts and analyzes the vocabulary,creating a word list,ontology discourse list,and grammar category word list for inscriptions,extracting formal variants and commonly used words,and quantitatively analyzing type-example ratio,word length distribution,and syllable entropy.Chapter 3 analyzes the nature and classification of the Tibetan language,provides a detailed description of the semantics and forms of genitive,ergative systems,spatial categories,comparative cases,and associative cases in the corpus category,and gives parallel sentence examples.Chapter 4 summarizes and looks forward to the work of the whole article,pointing out its innovative points and areas for future improvement.The innovation of this study.A knowledge base of bibliographic ontology with multidimensional characteristics has expanded the scope of knowledge engineering applications,making it adaptable to multidisciplinary studies such as linguistics,bibliography,and computer engineering.By verifying language facts based on corpus analysis and graph tools,a stable and sustainable research program has been formed,which can also retrieve and generate structured language data in real time with practicality.In the study of Tibetan language during the Tubo period,a comprehensive approach using graph tools and linguistic typology theory was employed to interpret grammatical cases and analyze errors,providing new ideas and means for the study of inscriptions.
