Supplementary data for the readability and the structural accuracy analysis of the OBO Foundry ontologies. The ontologies used in this analysis are available at https://doi.org/10.5281/zenodo.6363060.
-
The data folder initially contains the several files with links to download both the member and the candidate OBO Foundry ontologies. Additionally, a csv table including both the acronym and the complete title of the OBO Foundry ontologies has been included.
-
The scripts folder contains the following scripts:
- get_ontologies.sh: Bash script to download the latest version of the OBO Foundry ontologies into the data/ontologies folder.
- metrics.jar: Command line based java application to obtain the readability and the structural accuracy metrics for a set of ontologies. The source code is available here.
- getMetricsMembers.sh: Bash script to obtain the metrics for the OBO Foundry member ontologies. This script read the folder /data/ontologies/member_ontologies and put the results in /results/members_results.
- getMetricsMembers.sh: Bash script to obtain the metrics for the OBO Foundry candidate ontologies. This script read the folder /data/ontologies/candidate_ontologies and put the results in /results/candidates_results.
- descriptive_analysis.R: R script intended to be opened in an interactive rstudio session. It contains the R commands used to perform the descriptive analysis, including basic statistics and plots. It also includes commented lines that help to follow the script.
- evaluome.R: R script that performs a metric analysis by using evaluome library, among others. This includes a clustering analysis to find optimal metric partitions. The script is intended to be opened in an interactive rstudio session.
- correlation_analysis.R: R script that performs a correlation analysis between the systematic naming value of the lexical regularity classes and their number of transitive subclasses. The script is intended to be opened in an interactive rstudio session.
-
The results folder contains several subfolders and files with the results provided by each step, namely:
- candidates_results: Folder including TSV files for each candidate ontology, including its metric values. A file called allMetrics.tsv is also included, in which the information about all the candidate ontologies is merged.
- members_results: Folder including TSV files for each member ontology, including its metric values. A file called allMetrics.tsv is also included, in which the information about all the member ontologies is merged.
- detailed_files: Folder including detailed files for each (ontology, metric) pair, including extra information at entity level.
- systematic_naming_correlation_subclass.csv: File with the results of the correlation analysis between the number of transitive subclasses of a lexical regularity class and its score for the systematic naming metric. This is a CSV file indicating, for each evaluated ontology, its number of lexical regularity classes, the Spearman correlation obtained between the number of transitive subclasses of a lexical regularity class and its score for the systematic naming metric, and the corresponding p-value indicating the significance.

The first step to reproduce our results is to download this repository into your computer with the command:
git clone https://github.com/fanavarro/lexical-analysis-obo-foundry.git
Once the repo is downloaded, enter into the folder:
cd lexical-analysis-obo-foundry
The first step to reproduce our results is to download the ontologies that we analysed. This could be done in two ways. On the one hand, we provide a bash script that downloads the latest version of the ontologies from the OBO Foundry. On the other hand, we provide a Zenodo persistent link that contains the concrete versions used in our analysis.
We provide a bash script that we used for downloading the ontologies. Note that this script will download the latest version of the ontologies so changes could have been done on them. If you want to download the ontologies used in the article, please go to Download the ontologies from Zenodo. This script reads the download links for each ontology from the files candidates_download_links.txt and members_download_links.txt. The downloaded ontologies are saved by default in the folders lexical-analysis-obo-foundry/data/ontologies/candidate_ontologies and lexical-analysis-obo-foundry/data/ontologies/member_ontologies.
To run the script:
# Enter in scripts folder
cd scripts
# Execute the script
bash get_ontologies.sh
Please, check that the ontologies are in the folders lexical-analysis-obo-foundry/data/ontologies/candidate_ontologies and lexical-analysis-obo-foundry/data/ontologies/member_ontologies after running the script in order to verify that everything worked well.
In order to assess reproducibility, we uploaded the concrete versions of the ontologies we used for the study in the Zenodo platform at https://doi.org/10.5281/zenodo.4701571. Download the provided zip files for the candidate ontologies (candidate_ontologies.zip) as well as the member ontologies (member_ontologies.zip) and extract them in the folder lexical-analysis-obo-foundry/data/ontologies/ so that you have the following folders:
- lexical-analysis-obo-foundry/data/ontologies/candidate_ontologies
- lexical-analysis-obo-foundry/data/ontologies/member_ontologies
The next step is to calculate the metrics for the ontologies previously downloaded. To achieve this, we provide the java application metrics.jar, located at the scripts folder. This application has the following parameters:
- -i,--input arg The input. It can be a single ontology provided in OWL format, or a folder containing a set of ontologies in OWL format.
- -o,--output arg The output. It will be a TSV file including the metrics for the ontology in the input.
- -v,--detailed-files If present, generate a report for each metric-ontology pair, consisting in detailed information at ontology class level.
Furthermore, we provide two bash scripts that encapsulates the use of metrics.jar to calculate the metrics for candidate and member ontologies:
-
getMetricsCandidates.sh: Calculate the metrics for the candidate ontologies, which are taken from the folder lexical-analysis-obo-foundry/data/ontologies/candidate_ontologies. The results are saved into the folder lexical-analysis-obo-foundry/results/candidates_results. This will create one TSV file per ontology including all the metrics for that ontology, together with a log file. Furthermore, a file called allMetrics.tsv will be also created, including all the metrics for all the ontologies. Moreover, detailed_files will be created into the detailed_files folder.
-
getMetricsMembers.sh: Calculate the metrics for the member ontologies, which are taken from the folder lexical-analysis-obo-foundry/data/ontologies/member_ontologies. The results are saved into the folder lexical-analysis-obo-foundry/results/members_results. This will create one TSV file per ontology including all the metrics for that ontology, together with a log file. Furthermore, a file called allMetrics.tsv will be also created, including all the metrics for all the ontologies. Moreover, detailed_files will be created into the detailed_files folder.
Run the following commands to execute these scripts:
# Go to the scripts folder (assuming that you are on the root folder of this repository)
cd scripts
# Get metrics for the member ontologies
bash getMetricsMembers.sh
# Get metrics for the candidate ontologies
bash getMetricsCandidates.sh
# Move detailed files to the results folder
mv detailed_files ../results/
Once the above commands are executed, your results folder will contain a three folders:
- candidates_results: logs and TSV files with the metrics obtained for each candidate ontology. The file allMetrics.tsv contains the information about all the candidate ontologies and their metrics.
- members_results: logs and TSV files with the metrics obtained for each member ontology. The file allMetrics.tsv contains the information about all the member ontologies and their metrics.
- detailed_files: Set of TSV files including a more detailed information about each ontology-metric pair.
The descriptive analysis, the metric partition analysis and the correlation analysis were performed by using the rstudio software. In order to reproduce them, open rstudio and load the corresponding file (descriptive_analysis.R for the descriptive analysis; evaluome.R for the metric partition analysis, or correlation_analysis.R, for the correlation analysis). Then, you can execute any of them line by line in an interactive way. Furthermore, these files include comments to clarify each section.
