+<!-- Provide a quick summary of what the dataset is or can be used for. -->
+## Dataset Details
+The Character Similarity Dataset is a collection of textual trait descriptions along with the corresponding ontology based similarity measures between trait description pairs. The distance is estimated using the [Phenoscape Knowledgebase](https://kb.phenoscape.org/) as the ontology.
+### Dataset Description
+- **Curated by:** Jim Balhoff, Soumyashree Kar, Juan Garcia, Hilmar Lapp
+- **Language(s) (NLP):** English
+- **Repository:** [Imageomics/char-sim](https://github.com/Imageomics/char-sim)
+- **Paper:** Coming soon!
+The Character Similarity Dataset is a collection of 19K textual trait descriptions of fish collected from the [Phenoscape Knowledgebase](https://kb.phenoscape.org/). The dataset also contains the corresponding pairwise similarity measures between trait descriptors (i.e., maxIC, Jaccard, SimGIC). These metrics estimate semantic similarity between the ontological representation of the traits descriptions per the Phenoscape Knowledgebase. The goal is to use this pairwise similarities to inform an embedding space that preserves the structure of the underlying ontology.
+### Supported Tasks and Leaderboards
+Task: Aligned feature extraction. Metric: Spearman's correlation coefficient.

+`phenex-data-merged.ofn.gz` and `phenoscape-kb-tbox-classified.ttl.gz` contain URLs to access the trait data from [Phenoscape Knowledgebase](https://kb.phenoscape.org/). Running the processing script creates the four subset folders (`characiformes/`, `cypriniformes/`, `gymnotiformes/`, and `siruliformes/`, each an order of fish), then combines their data into the `all/` directory to create the training and test datasets.
+Note: `percentage` is the parameter passed for the percentage of the data to use for training; in this case, `percentage = 80`.
+### Data Instances
+Percentage is the proportion of data that will be used for training (i.e. data_{percentage}p_TRAINING.tsv.gz). In case the percentage is smaller than 100, the remaining proportion of the dataset is stored in data{percentage}p_ALL_NON_TRAIN.tsv.gz and a subset of this in data_{percentage}p_NON_OVERLAP.tsv.gz. Each of this files corresponds to a

+Describe the types of the data files or the columns in a CSV with metadata.
+Ex:
+**metadata.csv**:
+  - `img_id`: Unique identifier for the dataset.
+  - `specimen_id`: ID of specimen in the image, provided by museum data source. There are multiple images of a single specimen.
+  - `species`: Species of the specimen in the image. There are N different species of <genus> of <animal>.
+  - `view`: View of the specimen in the image (e.g., `ventral` or `dorsal` OR `top` or `bottom`, etc.; specify options where reasonable).
+  - `file_name`: Relative path to image from the root of the directory (`<species>/<img_id>.png`); allows for image to be displayed in the dataset viewer alongside its associated metadata.

+## Dataset Creation
+### Curation Rationale
+[More Information Needed]
+<!-- Motivation for the creation of this dataset. For instance, what you intended to study and why that required curation of a new dataset (or if it's newly collected data and why the data was collected (intended use)), etc. -->
+### Source Data
+Data was collected from the [Phenoscape Knowledgebase](https://kb.phenoscape.org/).
+<!-- This section describes the source data (e.g., news text and headlines, social media posts, translated sentences, ...). As well as an original source it was created from (e.g., sampling from Zenodo records, compiling images from different aggregators, etc.) -->
+#### Data Collection and Processing
+<!-- This section describes the data collection and processing process such as data selection criteria, filtering and normalization methods, re-sizing of images, tools and libraries used, etc.
+This is what _you_ did to it following collection from the original source; it will be overall processing if you collected the data initially.
+-->
+#### Who are the source data producers?
+[More Information Needed]
+<!-- This section describes the people or systems who originally created the data.
+Ex: This dataset is a collection of images taken of the butterfly collection housed at the Ohio State University Museum of Biological Diversity. The associated labels and metadata are the information provided with the collection from biologists that study butterflies and supplied the specimens to the museum.
+ -->
+### Annotations
+<!--
+If the dataset contains annotations which are not part of the initial data collection, use this section to describe them.
+Ex: We standardized the taxonomic labels provided by the various data sources to conform to a uniform 7-rank Linnean structure. (Then, under annotation process, describe how this was done: Our sources used different names for the same kingdom (both _Animalia_ and _Metazoa_), so we chose one for all (_Animalia_). -->
+#### Annotation process
+[More Information Needed]
+<!-- This section describes the annotation process such as annotation tools used, the amount of data annotated, annotation guidelines provided to the annotators, interannotator statistics, annotation validation, etc. -->
+#### Who are the annotators?
+[More Information Needed]
+<!-- This section describes the people or systems who created the annotations. -->
+### Personal and Sensitive Information
+None
+## Considerations for Using the Data
+The distribution of SimGIC scores is skewed towards smaller values. This imbalance may cause the similarity of embeddings to follow the same bias. Consider subsampling to ensure uniform representation of distances.
+### Bias, Risks, and Limitations
+This dataset has the biases of the Phenoscape ontology. This means the estimated models embeddings will inherit the ontology's inductive biases, coverage gaps, and evolving definitions. Biological conclusions may differ under alternative metrics (e.g., [Resnik](ADD LINK)) or other phenotype ontologies.
