+
+The dataset includes 375,084 example sentences (187200 positive, 187884 negative), each including a pair of entities and the engineering design relation between these.
+The dataset was manually constructed using sentences in 4,205 patents granted by USPTO, stratified according to 130 classes.
+
+The dataset is used to train token classification and Seq2Seq transformer models to populate explicit engineering design facts from artefact descriptions.
+
+More details in the following paper.
+Siddharth, L., Luo, J., 2024. Retrieval-Augmented Generation using Engineering Design Knowledge. arXiv (cs.CL) https://arxiv.org/abs/2307.06985.
+
+In each example, 
+The input is a pair of entities is marked in a sentence using {HEAD ~ ...} and {TAIL ~ ...} notations. 
+The output is the relation between the pair of entities as identified using actual tokens in the sentence. If there is no relation, the output in None.
+
+The dataset could be used to train Seq2Seq models, i.e., marked sentence --> relation.
+The dataset could also be used to train token classification models, i.e., tokenized marked sentence --> token tags.
