+# MovieSum: An Abstractive Summarization Dataset for Movie Screenplays
+
+## Dataset Summary
+
+MovieSum consists of 2,200 movie screenplays and their corresponding Wikipedia summaries. It is a long-form summarization task where the mean length of movie screenplays is approximately 34K. We manually formatted the movie screenplays to represent their structural elements. We also provide the IMDB ID for each movie to facilitate the collection of additional metadata.
+
+## Dataset Statistics
+|                 |     |
+|----------------------------|-----------------|
+| **Total Movie Screenplays**    | 2,200           |

+| **Mean Summary Length**        | 793             |
+
+Each movie screenplay is in XML format with the following DOM structure:
+
+```
+<script>
+<scene>
+<stage_direction>..</stage_direction>
+<scene_description>...</scene_description>
+<character>..</character>
+<dialogue>..</dialogue>
+...
+</scene>
+<scene>
+...
+</scene>
+<script>
+
+```
+
