Predicting Humorousness and Metaphor Novelty with Gaussian Process Preference Learning

This project contains source code and data for a Gaussian Process Preference Learning (GPPL) system for predicting humorousness and metaphor novelty.

Abstract: The inability to quantify key aspects of creative language is a frequent obstacle to natural language understanding. To address this, we introduce novel tasks for evaluating the creativeness of language—namely, scoring and ranking text by humorousness and metaphor novelty. To sidestep the difficulty of assigning discrete labels or numeric scores, we learn from pairwise comparisons between texts. We introduce a Bayesian approach for predicting humorousness and metaphor novelty using Gaussian process preference learning (GPPL), which achieves a Spearman's ρ of 0.56 against gold using word embeddings and linguistic features. Our experiments show that given sparse, crowdsourced annotation data, ranking using GPPL outperforms best–worst scaling. We release a new dataset for evaluating humour containing 28,210 pairwise comparisons of 4030 texts, and make our software freely available.

Dependencies

  • Python 3

For running the experiments, please see the requirements.txt. We recommend using a virtual environment to install the packages:

python -m venv env
source env/bin/activate
pip install -r requirements.txt 

Project Structure

  • data -- a folder containing small data files + default place to generate dataset files for the experiments
  • python -- the scripts for running the experiments
  • python/humour_dataset -- script used to remove workers who failed a captcha test, i.e. to detect spammers
  • python/models -- the implementation of the GPPL method
  • python/preprocessing -- methods used to extract frequency and bigram features
  • python/tools --
  • results -- an output directory for storing results

How to run the experiments

Before running the experiments which use word embeddings, please unzip the file data/embeddings.tar.bz2 . Before running the experiments with the metaphor novelty dataset, please unzip the file data/all.zip.

Task 1

For the humour dataset, run GPPL:

python run_task1_experiment.py humour

Now, look in the results directory to see the output from the first step. In Task_1_analysis_humour.py, change the resfile variable to point to the new results csv file. Next, run:

python Task_1_analysis_humour.py

This will produce plots in results directory and output a number of correlation measures shown in the paper. It will also show classification performance in separating funny and non-funny texts (using the AUC metric), and inter-annotator agreement.

The same process can be used for metaphor novelty data:

python run_task1_experiment.py metaphor

Now, set the resfile variable in Task_1_analysis_metaphor.py to the results csv file from the previous step, which is in the results directory. Then run:

python Task_1_analysis_metaphor.py

This will produce another plot in the results directory and output correlation measures to the command line.

Task 2

For the humour dataset:

python run_experiments.py humour

For the metaphor dataset:

python run_experiments.py metaphor

Task 3

For the humour dataset:

python run_experiments.py humour 0.05,0.1,0.2,0.33,0.66 

For the metaphor dataset:

python run_experiments.py metaphor 0.05,0.1,0.2,0.33,0.66

GPPL will be tested with both 'annotation' and 'pairs' strategies, as described in the paper. The model will be trained with frequency, ngram and average word embeddings features.

Task 4

For the humour dataset:

python run_experiments.py humour 0.05,0.1,0.2,0.33,0.66 task4 

For the metaphor dataset:

python run_experiments.py metaphor 0.05,0.1,0.2,0.33,0.66 task4
