## Dataset Description

### Dataset Summary
This dataset contains highly detailed information on each of the 51 matches in the UEFA Euro 2020 tournament composed and aggregated from 6 original csv files. Each row represents the information for each match and the columns constitute a wide range of variables on basic match information, referee information and statistics, match events in different phases of a match, team line-up and squad information, team statistics and player statistics on different areas of the game, and player-based pre-match information. 

### Data Processing
Please see the 'uefa_euro2020_processing.py' file for detailed processing code and procedures.

### Supported Tasks
The dataset preserves most of the supported tasks of the original source data. The new structure of the data also enables performing other tasks especially in terms of investigating the relationships between different level (individual player, team, match, match event, etc.) by composing and aggregating the original data. Some examples include:
- Extract and visualize key statistics for players, teams, referees, and other participants within and across matches.
- Investigate how key team statistics, such as shots on target and total distance covered, associate with the outcome of the match through EDA, regression analysis, feature importance analysis, or other methods.
- Explore the potential associations between certain player statistics and relevant team statistics.
- Analyze the change of tactics by a team over the tournament through its line up information and its team statistics.
- Investigate how pre-match tallies, such as goal streak, clean sheet streak, whether the player is benched in the previous match, and whether the player will be suspended if booked, affect a players' performance in the next match.
- Other data story-telling tasks about events during a match and across the tournament.
- Decompose the nested variables or the broader data structure for user-specific purposes.

### Languages
- English

## Dataset Structure

### Data Instance
For the flat variables without nested structures:
```
{
  "HomeTeamName": "Italy",
  "AwayTeamName": "England",
  "DateandTimeCET": "2021-07-11T21:00:00",
  "MatchID": 2024491,
  "RoundName": "final",
  "Stage": "Knockout Stage",
  "MatchDay": 7,
  "Session": 1,
  "MatchMinute": 120,
  "InjuryTime": 9,
  "NumberOfPhases": 2,
  "Phase": 5,
  "ScoreHome": 1,
  "ScoreAway": 1,
  "MatchStatus": "played",
  "StadiumID": 1100043,
  "RefereeWebName": "Kuipers",
  "TotalNumberofMatchesRefereed": 4,

}
```
For the nested variables, since the nested structures are complex and long, it will be difficult to show a complete instance here. I will instead provide the structure.

### Data Splits
Since the final dataset contains only 51 rows, and many supported tasks using this dataset might not need train-test-validation splits, I only keep one 1 split of train dataset.

## Dataset Creation

### Curation Rationale
The primary purpose of the creation of this dataset is to combine useful information on different levels of matches (individual player, team, match, event, etc.) to facilitate user access and insight-extraction from this tournament's data.

### Source Data
"UEFA Euro 2020" from “https://data.world/cervus/uefa-euro-2020".

## Limitations
If users hope to conduct advanced machine learning modeling using the dataset, the sample size might be too small to attain generalizable conclusions, and the preprocessing step could involve extensive parsing and flattening of variables. The dataset is more suitable for summrization, story telling, insight and feature extraction, and analysis rather than modeling. There are also a small number of missing data that could be hard to impute in the nested variables.
