 # exHarmony: Authorship and Citations for Benchmarking the Reviewer Assignment Problem
 
-The **exHarmony** dataset is designed for benchmarking the **Reviewer Assignment Problem (RAP)**, formulated as a **text retrieval** task. Given a paper (query), the goal is to retrieve relevant authors (documents) who are most suitable as reviewers.
 
 ## Dataset Summary
 
+**exHarmony** is a large-scale benchmark dataset for the **Reviewer Assignment Problem (RAP)**, reframing reviewer recommendation as an **information retrieval** task.
+It leverages publication metadata from **OpenAlex** to construct a collection of papers, their authors, citation links, and multiple **qrel definitions** for evaluation.
+
+The dataset allows researchers to systematically study reviewer recommendation under different assumptions of reviewer expertise (e.g., authorship, citation networks, and similarity-filtered citations).
+
+exHarmony was introduced in the paper:
+
+> *exHarmony: Authorship and Citations for Benchmarking the Reviewer Assignment Problem*
+> Ebrahimi, Salamat, Arabzadeh, Bashari, Bagheri (ECIR 2025)
+
 * **Collection split**: A large set of scientific papers used for indexing.
 * **Test split**: Papers held out for evaluation.
 * **Authors' works mapping**: Links each author to their published works.
 * **Authors' information**: Includes metadata such as citation counts, institutional affiliation, and years of experience.

+## Usage
+
+```python
+from datasets import load_dataset
+
+dataset = load_dataset("Reviewerly/exHarmony")
+
+# Example: Access paper collection
+papers = dataset["papers_collection"]
+print(papers[0])
+```

+## Qrel Files
+
+exHarmony provides **multiple qrels** to evaluate RAP under different assumptions:
+
+| Qrel Set              | Description                                                                                                                       |
+| --------------------- | --------------------------------------------------------------------------------------------------------------------------------- |
