The goal of MatchZoo is to provide a high-quality codebase for deep text matching research, such as document retrieval, question answering, conversational response ranking, and paraphrase identification. With the unified data processing pipeline, simplified model configuration and automatic hyper-parameters tunning features equipped, MatchZoo is flexible and easy to use.

Tasks Text 1 Text 2 Objective
Paraphrase Indentification string 1 string 2 classification
Textual Entailment text hypothesis classification
Question Answer question answer classification/ranking
Conversation dialog response classification/ranking
Information Retrieval query document ranking

Get Started in 60 Seconds

To train a Deep Semantic Structured Model, import matchzoo and prepare input data.

import matchzoo as mz

train_pack = mz.datasets.wiki_qa.load_data('train', task='ranking')
valid_pack = mz.datasets.wiki_qa.load_data('dev', task='ranking')
predict_pack = mz.datasets.wiki_qa.load_data('test', task='ranking')

Preprocess your input data in three lines of code, keep track parameters to be passed into the model.

preprocessor = mz.preprocessors.DSSMPreprocessor()
train_processed = preprocessor.fit_transform(train_pack)
valid_processed = preprocessor.transform(valid_pack)

Make use of MatchZoo customized loss functions and evaluation metrics:

ranking_task = mz.tasks.Ranking(loss=mz.losses.RankCrossEntropyLoss(num_neg=4))
ranking_task.metrics = [
    mz.metrics.NormalizedDiscountedCumulativeGain(k=3),
    mz.metrics.NormalizedDiscountedCumulativeGain(k=5),
    mz.metrics.MeanAveragePrecision()
]

Initialize the model, fine-tune the hyper-parameters.

model = mz.models.DSSM()
model.params['input_shapes'] = preprocessor.context['input_shapes']
model.params['task'] = ranking_task
model.params['mlp_num_layers'] = 3
model.params['mlp_num_units'] = 300
model.params['mlp_num_fan_out'] = 128
model.params['mlp_activation_func'] = 'relu'
model.guess_and_fill_missing_params()
model.build()
model.compile()

Generate pair-wise training data on-the-fly, evaluate model performance using customized callbacks on validation data.

train_generator = mz.PairDataGenerator(train_processed, num_dup=1, num_neg=4, batch_size=64, shuffle=True)

valid_x, valid_y = valid_processed.unpack()
evaluate = mz.callbacks.EvaluateAllMetrics(model, x=valid_x, y=valid_y, batch_size=len(pred_x))

history = model.fit_generator(train_generator, epochs=20, callbacks=[evaluate], workers=5, use_multiprocessing=False)
