**Dataset Description: Frappe Processed Dataset**

The Frappe dataset has been processed to refine the quality of user-item interactions by removing entries where either users or items had fewer than 5 interactions. This pruning resulted in a significant reduction in the dataset size:

- **Number of Users**: 651 (a reduction of 31.97% from the original dataset)
- **Number of Items**: 1127 (a reduction of 72.39%)
- **Total Number of Interactions**: 84,373 (a reduction of 12.30%)

**Columns Overview**:
The dataset includes 24 columns that capture a variety of features, structured as follows:

- **Basic Features**:
  - `user`: User identifier
  - `item`: Item identifier
  - `rating`: Rating given by the user
  - `cnt`: Count of interactions

- **Time of Day Features** (Encoded as one-hot):
  - `daytime_afternoon`
  - `daytime_evening`
  - `daytime_morning`
  - `daytime_night`
  - `daytime_noon`
  - `daytime_sunrise`
  - `daytime_sunset`

- **Weather Conditions** (Encoded as one-hot):
  - `weather_cloudy`
  - `weather_drizzle`
  - `weather_foggy`
  - `weather_rainy`
  - `weather_snowy`
  - `weather_stormy`
  - `weather_sunny`
  - `weather_unknown`

- **Weekend Indicator**:
  - `isweekend_weekend`
  - `isweekend_workday`

- **Location of Use (Home or Work)**:
  - `homework_home`
  - `homework_unknown`
  - `homework_work`

This dataset is designed for use in building Context-Aware Recommender Systems (CARS), offering rich features that capture temporal dynamics, environmental conditions, and user contexts, which are critical for personalized recommendations.
