Usage 使用

Click on left side of a cell to edit its contents. The tonal pattern hints will be shown on the right. Select rhyming dictionary and verse form from the tool bar. New cells will be automatically added once you filled up empty cells, or, you can manage them by clicking Cells from the menu bar. Add comments/title/attribution to your poem by preceding a line with a octothorpe (#).

Before you fill in a character, its correct tonal pattern is shown on the right in the corresponding position. After you do so, a color-coded icon is shown on the upper right corner, indicating the tonal pattern of the character, and whether it is acceptable, along with a line pointing to the error message if it is not. The checker follows the general rule of "一三五不论", yet also ensures that "孤平" and "三平调" errors do not occur. The rhyme of the poem is automatically inferred, and checked agianst each character that needs to rhyme.

You can open the rhyming dictionary as well as Kang Xi dictionary by clicking on < button on the right side of the tool bar. Type a character in the search bar, and it will be highlighted if it is in the current rhyme group. Press Enter to jump to the rhyme group it belongs to. Click on a character in the group to show its definition in Kang Xi dictionary.

Poem Analysis Tools 分析工具

You can see how your poem compares to those of Tang dynasty poets choosing from Analysis menu on the menu bar.

Bag-of-Words Embedding 词袋嵌入

A 1024D feature vector is generated for each of 256 Tang dynasty poets by applying bag-of-words model to their poems in Quan Tang Shi. A similar vector is generated for the user's poem. UMAP is used to reduce the dimension to 2, so the user can see where their poem lies in feature space among Tang dynasty poets. A list of nearest-neighbors are shown on the top left.

(Note on performance of the B-O-W model: When used on 24153 poems of 64 most prolific poets of Tang Dynasty, a classifier powered by finding nearest-neighbor of B-O-W vectors gives a Top-1 accuracy of 33.4%, Top-5 accuracy of 65.6%, and Top-10 accuracy of 79.8%.)

上图为在李商隐《杜工部座中离席》上的运行结果，该诗应为义山模仿杜甫风格的作品。算法运行结果显示两人皆在此诗风格相似度前十之内。 上图为在李商隐《韩碑》上的运行结果，该诗应为义山模仿韩愈风格的作品。算法运行结果显示两人皆在此诗风格相似度前十之内。

Line-wise Nearest Neighbor 逐句近邻

For each line in the user's poem, Quan Tang Shi is searched to find lines that are the most similar to it. This might help the user write better poems, as it shows how the great masters from the past delivered similar meanings.

上图为在清人黄景仁《绮怀》诗上的运行结果，该诗前两联应为化用李义山，为算法正确发掘。

Markov Chain Edit Suggestions 自动补全

Characters that are not filled or violate tonal rules in the current poem are automatically replaced with suggested edits. Optionally uses 对偶/对仗. The poetry style (诗风) can also be selected from those of Tang Dynasty poets. Although this functionality can also be used to generate entire poems (and it does so pretty well), such use is not encouraged as it does not coincide with the purpose of the software as an editor. Check out this project of mine for a full Chinese poetry generator.
