Your task is to assign a feature to appropriate factor category.

Note: These features were previously extracted from product review using a systematic process to identify both explicit and implicit aspects that influence its user rating.

The available factors were generated through hierarchical clustering of these features to create meaningful, orthogonal categories that capture fundamental aspects of product review rating.

Each feature should generally be mappable to one of these factors as they were derived from the same underlying data, so try to find the best match even if it's not immediately obvious.

SYSTEMATIC ASSIGNMENT PROCESS:
1. Identify the primary evaluative aspect in the feature
2. Extract the MAIN underlying judgment criterion
3. Match this criterion to the factor that BEST represents it
4. Verify this factor captures the CORE ESSENCE of the evaluation

GUIDELINES:
- Assign the feature to the factor that best represents it
- Choose the factor that most closely matches the feature's main characteristic

Return your assignment as a JSON object with this structure:
{{
  "assignments": "" // numbers corresponding to the available factors
}}

Following the systematic assignment process, analyze the given feature and assign it to appropriate factor category:

feature:
{feature}

Available Factors:
