Pre-trained Web Table Embeddings

The models here represent schema terms and instance data terms in a semantic vector space making them especially useful for representing schema and class information as well as for ML tasks on tabular text data.

The code for executing and evaluating the models is located in the table-embeddings Github repository

Quick Start

You can install the table_embeddings package to encode text from tables by running the following commands:

pip install cython
pip install git+https://github.com/guenthermi/table-embeddings.git

After that you can encode text with the following Python snippet:

from table_embeddings import TableEmbeddingModel
model = TableEmbeddingModel.load_model('ddrg/web_table_embeddings_plain150')
embedding = model.get_header_vector('headline')

Model Types

Model Type	Description	Download-Links
W-tax	Model of relations between table header and table body	(64dim, 150dim)
W-row	Model of row-wise relations in tables	(64dim, 150dim)
W-combo	Model of row-wise relations and relations between table header and table body	(64dim, 150dim)
W-plain	Model of row-wise relations in tables without pre-processing	(64dim, 150dim)
