We released annotated data for in-line mathematical expression detection.
If a word is a mathematical expression, the span of the word has the data-math attribute, whose value is B-Math or I-Math. These tags are based on simple BIO-tags, but O-Math is not annotated.
Licence of the data is the same as the licence of each paper. Most papers are licensed under CC-BY-NC-SA 3.0; the rest CC-BY 4.0. See LICENSE for the detail.
