Replicate Results

We provide pretrained models (all models were trained on a CPU) for text2edges(*)[last row of Table 2]. To replicate the results:

Step 1:

$ cd ./Text2ath/Scripts/Model/Trained_Models/

Unzip the pretrained models in the directory.

Step 2:

$ cd ./Text2Path/Scripts/Model/
$ sh get_reported_results.sh

Code for the MS-LSTM model can be found here

Usage

Step 1: Graph Preprocessing

Algorithm assumes that a graph is a rooted tree and it is represented as an edge list:

node1 node5
node2 node4
...

Furthermore each node in the graph must have a textual definition:

node1 text_def_1
node2 text_def_2
...

To preprocess a graph for a text2nodes model:

$ cd ./Text2Path/Scripts/Preprocessing/
$ sh make_path_node_representation_dataset.sh

To preprocess a graph for a text2edges model:

$ cd ./Text2Path/Scripts/Preprocessing/
$ sh make_artificial_vocab_representation_dataset.sh

One can get the pretrained word embeddings used in the experiments here

Step2 Train a Model:

To train a new model:

$ cd ./Text2Path/Scripts/Model/
$ python text_to_path_model.py --train_data <path_to_train_data> --augment_data <augment_data_file> --test_data <test_data_file> --checkpoint <save_model_file> --graph <graph_file> --is_train 1
