Before revision:  In contrast to the traditional framing analysis, which has been constrained by a small number of manually annotated general frames, our unsupervised approach provides much more detailed insights , by considering a host of semantic axes.
After revision:  In contrast to the traditional framing analysis, which has been constrained by a small number of manually annotated general frames, our unsupervised approach can be readily applied to large datasets because it does not require manual annotations. It can also provide more nuanced insights by considering a host of semantic axes.
