EduNLP.Pretrain

class EduNLP.Pretrain.GensimSegTokenizer(symbol='gms', depth=None, flatten=False, **kwargs)

Parameters

symbol – gms fgm

class EduNLP.Pretrain.GensimWordTokenizer(symbol='gm', general=False)

Parameters

• symbol – gm fgm gmas fgmas

• general – True when item isn’t in standard format, and want to tokenize formulas(except formulas in figure) linearly. False when use ‘ast’ mothed to tokenize formulas instead of ‘linear’.

Examples

>>> tokenizer = GensimWordTokenizer(symbol="gmas", general=True)
>>> token_item = tokenizer("有公式$\FormFigureID{wrong1?}$，如图$\FigureID{088f15ea-xxx}$,    ... 若$x,y$满足约束条件公式$\FormFigureBase64{wrong2?}$,$\SIFSep$，则$z=x+7 y$的最大值为$\SIFBlank$")
>>> print(token_item.tokens[:10])
['公式', '[FORMULA]', '如图', '[FIGURE]', 'x', ',', 'y', '约束条件', '公式', '[FORMULA]']
>>> tokenizer = GensimWordTokenizer(symbol="fgmas", general=False)
>>> token_item = tokenizer("有公式$\FormFigureID{wrong1?}$，如图$\FigureID{088f15ea-xxx}$,    ... 若$x,y$满足约束条件公式$\FormFigureBase64{wrong2?}$,$\SIFSep$，则$z=x+7 y$的最大值为$\SIFBlank$")
>>> print(token_item.tokens[:10])
['公式', '[FORMULA]', '如图', '[FIGURE]', '[FORMULA]', '约束条件', '公式', '[FORMULA]', '[SEP]', '[FORMULA]']
