Overview

Component to preprocess data for token classification task. See docs to learn more.

Version: 0.0.65

View in Studio: https://ml.azure.com/registries/azureml/components/token_classification_datapreprocess/version/0.0.65

Inputs

task arguments

sample input

{tokens_column: [ "EU", "rejects", "German", "call", "to", "boycott", "British", "lamb", "." ], ner_tags_column: '["B-ORG", "O", "B-MISC", "O", "O", "O", "B-MISC", "O", "O"]'}

For the above dataset pattern, token_key should be set as tokens_column and tag_key as ner_tags_column

Name Description Type Default Optional Enum
token_key Key for tokens in each example line string False
tag_key Key for tags in each example line string False
batch_size Number of examples to batch before calling the tokenization function integer 1000 True

Tokenization params pad_to_max_length: type: string enum: - "true" - "false" default: "true" optional: true description: If set to True, the returned sequences will be padded according to the model's padding side and padding index, up to their max_seq_length. If no max_seq_length is specified, the padding is done up to the model's max length.

Name Description Type Default Optional Enum
max_seq_length Default is -1 which means the padding is done up to the model's max length. Else will be padded to max_seq_length. integer -1 True

Data inputs Please note that either train_file_path or train_mltable_path needs to be passed. In case both are passed, mltable path will take precedence. The validation and test paths are optional and an automatic split from train data happens if they are not passed. If both validation and test files are missing, 10% of train data will be assigned to each of them and the remaining 80% will be used for training If anyone of the file is missing, 20% of the train data will be assigned to it and the remaining 80% will be used for training

Name Description Type Default Optional Enum
train_file_path Path to the registered training data asset. The supported data formats are jsonl, json, csv, tsv and parquet. uri_file True
validation_file_path Path to the registered validation data asset. The supported data formats are jsonl, json, csv, tsv and parquet. uri_file True
test_file_path Path to the registered test data asset. The supported data formats are jsonl, json, csv, tsv and parquet. uri_file True
train_mltable_path Path to the registered training data asset in mltable format. mltable True
validation_mltable_path Path to the registered validation data asset in mltable format. mltable True
test_mltable_path Path to the registered test data asset in mltable format. mltable True

Dataset parameters

Name Description Type Default Optional Enum
model_selector_output output folder of model selector containing model metadata like config, checkpoints, tokenizer config uri_folder False

Outputs

Name Description Type
output_dir The folder contains the tokenized output of the train, validation and test data along with the tokenizer files used to tokenize the data uri_folder
