+# UFLA-FORMS: an Academic Forms Dataset for Information Extraction in the Portuguese Language
+
+## About
+
+**UFLA-FORMS** is a manually labeled dataset of document forms in Brazilian Portuguese extracted from the domains of the <a href="https://ufla.br/">Federal University of Lavras (UFLA)</a>. The dataset emphasizes the hierarchical structure between the entities of a document through their relationships, in addition to the extraction of key-value pairs. Samples were labeled using <a href="https://github.com/Victorgonl/ToolRI/">ToolRI</a>.
+
+## Overview
+
+**UFLA-FORMS** comprises of 200 labeled samples containing 7,710 entities with 34,396 words and 4,442 relationships between them. Each sample is composed of a PNG image extracted from a filled form and a JSON file with it's metadata. The metadata covers labeling information such as sentences, bounding boxes, class labels and relationship pairs. Each entity of the samples were labeled into one of the four classes, according to the <a href="https://guillaumejaume.github.io/FUNSD/">FUNSD</a> dataset: Header, Question, Answer or Other. Images are available in the `image` folder and metadata in the `data` folder. Each sample has the same name (ranging from "000" to "199") for its image and respective metadata in the files names before extensions. A `dataset_info.json` file is available containing information about the dataset, including it's partitions defined for cross-validation and hold-out experiments.
