# Pre-trained Web Table Embeddings
|
17 |
+
|
18 |
+
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.
|
19 |
+
|
20 |
+
The code for executing and evaluating the models is located in the [table-embeddings Github repository](https://github.com/guenthermi/table-embeddings)
|
21 |
+
|
22 |
+
## Quick Start
|
23 |
+
|
24 |
+
You can install the table_embeddings package to encode text from tables by running the following commands:
|
25 |
+
|
26 |
+
|
27 |
+
```bash
|
28 |
+
pip install cython
|
29 |
+
pip install pip install git+https://github.com/guenthermi/table-embeddings.git
|
30 |
+
```
|
31 |
+
|
32 |
+
After that you can encode text with the following Python snippet:
|
33 |
+
|
34 |
+
```python
|
35 |
+
from table_embeddings import TableEmbeddingModel
|
36 |
+
model = TableEmbeddingModel.load_model('ddrg/web_table_embeddings_combo150')
|
37 |
+
embedding = model.get_header_vector('headline')
|
38 |
+
```
|
39 |
+
|

+
