【Purpose/significance】 The knowledge organization of tang poetry author style elements provides knowledge services for the

intelligent implementation for poets profiling in Tang Dynasty, which is an important breakthrough in authorship attribution for poetry in Tang Dynasty. It can provide support for the literature collection in digital humanities and cultural dissemination.【

Method/process】In this paper, we first reviewed the relevant theories of linguostylistics and summarized the evaluation methods and strategies on the style of Tang poetry provided by traditional humanities experts and scholars. We also reported the corpus and retrieval platform formed by digital humanities research on Tang poetry. Secondly, based on the domain knowledge provided by experts and particularity of Tang poetry, we established a systematic framework of Tang poetry style elements. In order to satisfied the demand of poets profiling, a de⁃tailed analysis was conducted from three dimensions: the authorship attribution element knowledge, stylistic feature element knowl⁃edge, and value attribution element knowledge, and provide a knowledge organization in different levels. 【Result/conclusion】 Applica⁃bility verification was conducted by selecting element knowledge from the knowledge organization, and the results showed that differ⁃ent dimensions of element knowledge can achieve corresponding poets profiling.【Innovation/limitation】 Research shows that the digi⁃tization of Tang poetry as ancient literature involves a large amount of theoretical and domain knowledge. However, we hardly recog⁃nized the difference between machine recognition and human recognition, which has led to a certain limitation in the research.
