|
- **Stable axes:** None
|
|

|
|
- **Parties with cross-ideological voting:** 0
|
|
|
|
## Axis Stability
|
|
|
|
**Stable axes (similarity > 0.7):** None
|
|
**Reordered axes:** [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
|
|
**Unstable axes:** []
|
|
|
|
## Semantic Drift
|
|
|
|
No drift data available (no stable axes or insufficient data).
|
|
|
|
## Party Voting Analysis
|
|
|
|
No cross-ideological voting detected.
|
|
|
|
## Methodology
|
|
|
|
- **Axis stability:** Jaccard similarity of top-N motion rankings per component across windows
|
|
- **Semantic drift:** Cosine distance between fused embedding centroids of top-N motions per axis
|
|
- **Inflection points:** Drift rate exceeding 2× median drift rate
|
|
- **Cross-ideological voting:** Parties voting 'voor' on motions where canonical opposite-wing parties have high loadings
