-# PathVQA
-
-PathVQA is a dataset of question-answer pairs on pathology images. The questions are similar to those in the
-American Board of Pathology (ABP) test. The dataset includes both open-ended questions and binary "yes/no"
-questions. The dataset is built from two publicly-available pathology textbooks: "Textbook of Pathology" and
-"Basic Pathology", and a publicly-available digital library: "Pathology Education Informational Resource"
-(PEIR). The copyrights of images and captions belong to the publishers and authors of these two books,
-and the owners of the PEIR digital library.<br> 
+## Dataset Description
+PathVQA is a dataset of question-answer pairs on pathology images. The dataset is intended to be used for training and testing 
+Medical Visual Question Answering (VQA) systems. The questions contained in the dataset are similar to those in the American 
+Board of Pathology (ABP) test. The dataset includes both open-ended questions and binary "yes/no" questions. The dataset is
+built from two publicly-available pathology textbooks: "Textbook of Pathology" and "Basic Pathology", and a publicly-available 
+digital library: "Pathology Education Informational Resource" (PEIR). The copyrights of images and captions belong to the 
+publishers and authors of these two books, and the owners of the PEIR digital library.<br>

-## Dataset Summary
+### Dataset Summary
 The data was obtained from the updated Google Drive link shared by the authors on Feb 15, 2023, 
 see the [commit](https://github.com/UCSD-AI4H/PathVQA/commit/117e7f4ef88a0e65b0e7f37b98a73d6237a3ceab)
 in the GitHub repository. This version of the dataset contains a total of 5,004 images and 32,795 question-answer pairs. 
 Out of the 5,004 images, 4,289 images are referenced by a question-answer pair, while 715 images are not used.
-There are a few duplicate image-question-answer triplets which occur more than once in the same split (training, validation, test).
