# Data Dictionary — CS2 Playstyle & Roles Dataset (2024)
**Row = player (unique by `steamid`).**
`*_t` = T side, `*_ct` = CT side, `*_overall` = combined.
---
## Identifiers
| Column | Type | Description |
|-------------------|--------|-------------|
| `steamid` | int64 | SteamID64 (primary key). |
| `player_name` | string | Player handle. |
| `team_clan_name` | string | Team name. |
| `map_count` | int32 | Number of maps included for this player in the aggregation window. |
---
## Core playstyle features
All percentages are on **0–100** scale.
| Column | Type | Units/Range | Definition |
|---------------------|--------|-------------|------------|
| `tapd_t` | float | seconds | **Time Alive Per Death** on T: mean time of death within rounds on T. |
| `tapd_ct` | float | seconds | TAPD on CT. |
| `tapd_overall` | float | seconds | Round-weighted mean across sides. |
| `oap_t` | float | % (0–100) | **Opening Attempt %** on T: opening duels participated / team T rounds × 100. |
| `oap_ct` | float | % (0–100) | OAP on CT. |
| `oap_overall` | float | % (0–100) | Round-weighted across sides. |
| `podt_t` | float | % (0–100) | **Proportion of Deaths Traded** on T within a 5s window. |
| `podt_ct` | float | % (0–100) | PODT on CT. |
| `podt_overall` | float | % (0–100) | Round-weighted across sides. |
| `pokt_t` | float | % (0–100) | **Proportion of Kills which were Trades** on T within a 5s window. |
| `pokt_ct` | float | % (0–100) | POKT on CT. |
| `pokt_overall` | float | % (0–100) | Round-weighted across sides. |
> **Trading window:** 5 seconds; opening duels are the first kill event of a round.
> All side/overall aggregations are **round-weighted across maps**.

## Positioning features — **team-relative ranking** (0.2–1.0)
Values are **ordinal ranks within a team on a given map**, scaled to the interval (0,1].
With 5 players and no ties, the set is `{0.2, 0.4, 0.6, 0.8, 1.0}` where **higher = typically further from teammates**.
**Sampling rules (to capture structured setups):**
- Pre-plant only; snapshots every **3s** starting **10s after freeze end**.
- Alive-only; include a player only when their side still has **exactly four alive teammates** (full 5v5).
- For each map and team: compute per-player **map-level means** from 3D distances, then convert to **team-relative ranks**.
- Finally, compute **round-weighted means across maps** for T, CT, and overall.
| Column | Type | Range | Definition |
|-------------------------|-------|---------|------------|
| `adnt_rank_t` | float | 0.2–1.0 | **Average Distance from Nearest Teammate** — team-relative rank on T (higher = more isolated). |
| `adnt_rank_ct` | float | 0.2–1.0 | ADNT rank on CT. |
| `adnt_rank_overall` | float | 0.2–1.0 | Round-weighted rank across sides. |
| `adat_rank_t` | float | 0.2–1.0 | **Average Distance from Average Teammate** — team-relative rank on T (higher = further from centre). |
| `adat_rank_ct` | float | 0.2–1.0 | ADAT rank on CT. |
| `adat_rank_overall` | float | 0.2–1.0 | Round-weighted rank across sides. |
> **Interpretation caveat:** These are **team-relative ranking scores**, not statistical percentiles and not physical units; they enable comparisons of *tendency within team* across different maps without map-size bias.

## Roles
| Column | Type | Description |
|----------------|--------|-------------|
| `role_t` | string | T-side role (Spacetaker/Lurker/Half-Lurker/AWPer). |
| `role_ct` | string | CT-side role (Anchor/Rotator/Mixed/AWPer). |
| `role_overall` | string | Overall/primary role label. |
