Researchers have introduced a new task called Compositionality Trend Prediction to model gradual changes in the meaning and compositionality of noun compounds over time. Their study, focusing on German and English compounds across several decades, found only a small negative trend in compositionality, contrary to existing hypotheses. Computational experiments indicated that models trained on narrower time slices performed better than those trained on extensive historical data, and static representations were competitive with contextual ones for this task.
