AMORE-UPF                                                             UPF


Accompanying code for our participating system AMORE-UPF at SemEval 2018 Task 4: Character Identification on Multiparty Dialogues. See the link below for our paper with the system description.


For training, testing, or evaluation, run the script with the corresponding parameters (more details to the different phases are given below):

python --phase <phase> [-c <config_file>] [--model <model_path>] [--deploy_data <path_to_data>] [--no_cuda] [--no_eval]


  • phase can be train or deploy (optionally runs evaluation)
  • config_file specifies the hyperparameter settings. Is obligatory for training.
  • model_path specifies the path to the model. It is obligatory for the deploy phase.
  • deploy_data gives the path to the data for which the model has to output predictions (in CONLL format) (phase: deploy)
  • no_eval applies to the deploy phase. It can be set if you do not want to evaluate the model, but just want to obtain predictions for some input data. If the input data does not contain target entity ids, no_eval is set by default.
  • no_cudais set to run the system in CPU mode.

SemEval task data

First please download the SemEval datasets by running the script from within the semeval-task4 folder. (Alternatively, you can download the data yourself from the organizers' github. Store them in the folder data/friends.)

Running and evaluating the AMORE-UPF model on the SemEval test data

python --deploy_data test --model models/semeval-winning-model/amore-upf [--no_cuda]

This will produce the following output files, saved in the directory models/semeval-winning-model/answers/friends_test_scene/ :

  • amore-upf--ensemble.csv
    The answer file: It has three columns (called index, prediction, target),
    where each row contains the index of the target mention in the test data, the predicted entity id, and the gold entity id to which the mention refers

  • amore-upf--ensemble_scores.txt
    The evaluation results.

  • amore-upf--ensemble_matrix.csv
    A confusion matrix.

  • amore-upf.ini
    The used config file.


The demo describes how to train, deploy and evaluate a model from scratch using the official trial data of the SemEval task. If you have not used the script (see the section on task data above) for data download, you first need to get the trial data here.


python --phase train -c config_demo.ini [-r] [--no_cuda]

where the optional parameter

  • r is used to activate random sampling of hyperparameters from intervals specified in the config file. (see config_demo.ini for details)
  • See above for the description of the other parameters.

The system will produce a subfolder <year_month> in the models directory, in which it will store several files:

  • the config file
  • the model file (or files, if run with cross-validation, see parameter folds in the config),
  • a logs subfolder with the training log (it records the loss, accuracy etc. on the training and validation data for each epoch).

The files will contain a timestamp in their name in the format <yyyy_mm_dd_hh_mm_ss>.

For example, running the command above in April 2018 will train a model with 2-fold cross-validation, and produce something like

|__ `models/2018_04/`
|  |  `fixed--2018_04_19_17_58_14.ini`
|  |  ``
|  |  ``
|  |__`logs/`
|      | `fixed--2018_04_19_17_58_14.log`
|      | `fixed--2018_04_19_17_58_14.ini`

The prefix fixed means that the model was trained using fixed hyperparameters (since parameter r was not set, see above).

Using pre-trained word embeddings

Note that the model in this demo initialises the token embeddings randomly. If you want to use the pre-trained Google News skip-gram word embeddings (as AMORE-UPF does), you first need to download the data. You can do so either by setting the parameter in GET_GOOGLE_NEWS_EMBEDDINGS in to true and running the script again. Or you can directly download the vectors from here: GoogleNews-vectors-negative300.bin.gz. Put this in the data/ folder.
In config_demo.ini, set the parameter token emb to google_news.


Evaluate the model on the trial data

The system was trained using 2-fold cross-validation. So for evaluation on the trial data (on which it was trained), it averages the scores of each fold's models obtained on the respective test split:

python --phase deploy --deploy_data trial --model models/2018_04/fixed--2018_04_20_11_28_19 [--no_cuda]

This will produce a subfolder answers/friends_trial_scene/ in the model subfolder models/2018_04/. See the Section above for the description of the files stored therein.

Evaluate the model on the test data

python --phase deploy --deploy_data test --model models/2018_04/fixed--2018_04_20_11_28_19 [--no_cuda]

See the Section above for details.

Deploying: Run the trained system on an input document

python --phase deploy --deploy_data <path_to_data> --model <path_to_model> [--no_cuda] [--no_eval]


  • <path_to_model> specifies the path and the prefix of the model file, e.g.,
  • <path_to_data> gives the path to the data file, e.g.,
  • no_eval can be set if you do not want to evaluate the model, but just want to obtain predictions for some input data. If the input data does not contain target entity ids, no_evalis set by default.
