Center node: "flexible computing services for comparisons and analyses of classical chinese poetry"
  Abstract: We collect nine corpora of representative Chinese poetry for the time span of 1046 BCE and 1644 CE for studying the history of Chinese words, collocations, and patterns. By flexibly integrating our own tools, we are able to provide new perspectives for approaching our goals. We illustrate the ideas with two examples. The first example show a new way to compare word preferences of poets, and the second example demonstrates how we can utilize our corpora in historical studies of the Chinese words. We show the viability of the tools for academic research, and we wish to make it helpful for enriching existing Chinese dictionary as well.

Connected through hyperedge HE-1 (induced by source paper "computing len for exploring the historical people s social network"):
  with members:
    - "node2vec scalable feature learning for networks"
    - "tracking words in chinese poetry of tang and song dynasties with the china biographical database"
    - "deepwalk online learning of social representations"
