How to Get Started With the Model

Install Python package

SGnlp is an initiative by AI Singapore's NLP Hub. They aim to bridge the gap between research and industry, promote translational research, and encourage adoption of NLP techniques in the industry. <br><br> Various NLP models, other than cross lingual cross domain are available in the python package. You can try them out at SGNLP-Demo | SGNLP-Github.

pip install sgnlp

Examples

For more full code guide, please refer to this documentation. <br> Alternatively, you can also try out the demo for Cross Lingual Cross Domain.

Example of Undersupervised Feature Decomposition (UFD) model (German language):

from sgnlp.models.ufd import UFDModelBuilder, UFDPreprocessor

# Instantiate model builder and preprocessor
model_builder = UFDModelBuilder(
    source_domains=['books'],
    target_languages=['de'],
    target_domains=['dvd'])
preprocessor = UFDPreprocessor()

# Build pretrained model groups
model_groups = model_builder.build_model_group()


# Model predict ('books_de_dvd' model example)
instance = """Wolverine is BACK Der Film ist im Grunde wie alle Teile der X-Men für Comic-Fans auf jeden Fall ein muss.
              Hugh Jackman spielt seine Rolle wie immer so gut was ich von den ein oder anderen Darsteller leider nicht
              sagen kann. Story und Action sind aber genug Gründe um sich die Blu-ray zu kaufen."""

instance_features = preprocessor([instance])
output = model_groups['books_de_dvd'](**instance_features)
