Abstract:

[Background/ Meaning] Historical text is the basic material of historical research. By crawling the content of the text, historians organize, piece together and contextualize meaningful information in the text. History is a discipline that studies the trajectory of human activities in time. After adding the concept to geographic space, historical texts will become more three-dimensional. Instead of linear reading in paper data in the past, historical texts in the information age can add a lot of vocabulary tags with the assistance of technology, and then use the analysis and visualization of tagged vocabulary to take a bird’s eye view and grasp the implicit context in historical texts. [Process/ Method] By discussing the meaning of person, time, place name and object vocabulary marks in historical texts for historical research, describing the purpose and characteristics of various marks, especially pointing out that vocabulary marks not only identify words, but also need to achieve “disambiguation” With the “aggregation”function. At the same time introduce two automatic tagging tools, “Code Library Semi -automatic Marking Platform for Ancient Books”（MARKUS) and“Batch Tagging Tool”（Content Tagging Tool, CT) .These two tools make it possible to quickly mark  a large number of people, times, places, and things.[Results/Conclusions] Illustrate how to use marked texts through actual research results; use time, person, geography, and object vocabulary to mark actual benefits to illustrate the use of vocabulary marking and application in historical texts and historical research. Finally, we discuss the issue of event markers, and point out that event markers are essentially different from other lexical markers.
