+### Dataset Summary
 
-Statistics: 
+This large dataset was created by crowdsourcing 37,884 goal-oriented dialogs, covering 227 tasks in 47 domains. Domains include bus schedules, apartment search, alarm setting, banking, and event reservation. Each dialog was grounded in a scenario with roles, pairing a person acting as the bot and a person acting as the user. (This is the Wizard of Oz reference—using people behind the curtain who act as the machine). Each pair were given a domain and a task, and instructed to converse for 10 turns to satisfy the user’s queries. For example, if a user asked if a bus stop was operational, the bot would respond that the bus stop had been moved two blocks north, which starts a conversation that addresses the user’s actual need.
 
-|       | \# dialogues | \# utterances | avg. turns | avg. tokens | \# domains |
-| ----- | ------------ | ------------- | ---------- | ----------- | ---------- |
-| train | 37884         | 362450       | 9.57    | 7.66       | -          |

+- **How to get the transformed data from original data:** 
+  - Download [metalwoz-v1.zip](https://www.microsoft.com/en-us/download/58389) and [metalwoz-test-v1.zip](https://www.microsoft.com/en-us/download/100639).
+  - Run `python preprocess.py` in the current directory.
+- **Main changes of the transformation:**
+  - `CITI_INFO`, `HOME_BOT`, `NAME_SUGGESTER`, and `TIME_ZONE` are randomly selected as the valiation domains.
+  - Remove the first utterance by the system since it is "Hello how may I help you?" in most case.
+  - Add goal description according to the original task description: user_role+user_prompt+system_role+system_prompt.
+- **Annotations:**
+  - domain, goal
