QuoraParaphraseDatasetReader(self, tokenizer:allennlp.data.tokenizers.tokenizer.Tokenizer=None, token_indexers:Dict[str, allennlp.data.token_indexers.token_indexer.TokenIndexer]=None, **kwargs) -> None
Reads a file from the Quora Paraphrase dataset. The train/validation/test split of the data comes from the paper [Bilateral Multi-Perspective Matching for Natural Language Sentences] (https://arxiv.org/abs/1702.03814) by Zhiguo Wang et al., 2017. Each file of the data is a tsv file without header. The columns are is_duplicate, question1, question2, and id. All questions are pre-tokenized and tokens are space separated. We convert these keys into fields named "label", "premise" and "hypothesis", so that it is compatible to some existing natural language inference algorithms.
- tokenizer :
Tokenizer, optional Tokenizer to use to split the premise and hypothesis into words or other kinds of tokens. Defaults to
- token_indexers :
Dict[str, TokenIndexer], optional
- __Indexers used to define input token representations. Defaults to
QuoraParaphraseDatasetReader.text_to_instance(self, premise:str, hypothesis:str, label:str=None) -> allennlp.data.instance.Instance
Does whatever tokenization or processing is necessary to go from textual input to an
Instance. The primary intended use for this is with a
~allennlp.predictors.predictor.Predictor, which gets text input as a JSON
object and needs to process it to be input to a model.
The intent here is to share code between :func:
_read and what happens at
model serving time, or any other time you want to make a prediction from new data. We need
to process the data in the same way it was done at training time. Allowing the
DatasetReader to process new text lets us accomplish this, as we can just call
DatasetReader.text_to_instance when serving predictions.
The input type here is rather vaguely specified, unfortunately. The
have to make some assumptions about the kind of
DatasetReader that it's using, in order
to pass it the right information.
