+# Omanic
+
+
+The dataset contains two splits:
+
+- `OmanicSynth`: 10,296 machine-generated training examples.
+- `OmanicBench`: 967 expert-reviewed, human-annotated evaluation examples.
+
+Each row is a single 4-hop reasoning instance.
+
+
+For more details, please refer to the paper: [Omanic: Towards Step-wise Evaluation of Multi-hop Reasoning in Large Language Models](https://arxiv.org/abs/2603.16654).
+
+
+
+## Data Fields
+
+Each example contains the following top-level keys:
+
+- `id`: A unique example identifier.
+- `single_hop`: A list of decomposed single-hop sub-questions that form the reasoning chain. In Omanic, this chain is typically 4 hops long.
+- `multi_hop_question`: The final multi-hop question.
+- `multi_hop_answer`: The gold final answer to the multi-hop question.
+- `multiple_choice_options`: The final answer options for the multi-hop question. In the Omanic, these are the same as the options for the last single-hop question.
+- `correct_answer_label`: The correct option label for the final multi-hop question, typically one of `A`, `B`, `C`, or `D`.
+- `motif_type`: The reasoning graph topology of the multi_hop_question. Common values include `Bridge`, `Chain`, and `Converging`.
+  - `Bridge`: the answer to `Step1` must appear in the question for `Step2`, and the answers to `Step2` and `Step3` must both appear in the question for `Step4`.
+  - `Chain`: each step's question must contain the answer from the immediately preceding step.
+  - `Converging`: the answers to `Step1` and `Step2` must both appear in the question for `Step3`, and the answer to `Step3` must appear in the question for `Step4`.
+  
+  Here, `StepX` refers to the X-th sub-question in `single_hop`.
+
+
+### `single_hop`
+
+`single_hop` is a list of 4 sinle-hop questions. Each element describes one intermediate reasoning step and typically contains:
+
+- `question`: The single-hop sub-question for this reasoning step.
+- `answer`: The gold answer to this sub-question.
+- `multiple_choice_options`: The multiple-choice options for this hop.
+- `correct_answer_label`: The correct option label for this hop.
+- `domain`: The semantic domain assigned to this hop, such as history, science, economics, or culture. This element is present for every hop except the first one.
