摘要:

我们目前正在进行的工作,在名名复合词的组合性的时间进程。以前的工作提出了计算方法来确定化合物的组成。这些方法尝试自动确定复合词整体含义相对于其部分含义的透明度。我们假设这样的属性可能会随着时间的推移而改变。我们使用的时间戳的谷歌图书语料库为我们的历时调查,并首先检查是否从这个语料库中提取的基于向量的语义空间能够预测组合性评级,尽管其固有的局限性。我们发现,使用时间信息有助于预测的评级,虽然与评级的相关性低于其他语料库。最后,我们展示了一系列化合物随时间的变化。

英文摘要:

We present work in progress on the temporal progression of compositionality in noun-noun compounds. Previous work has proposed computational methods for determining the compositionality of compounds. These methods try to automatically determine how transparent the meaning of the compound as a whole is with respect to the meaning of its parts. We hypothesize that such a property might change over time. We use the time-stamped Google Books corpus for our diachronic investigations, and first examine whether the vector-based semantic spaces extracted from this corpus are able to predict compositionality ratings, despite their inherent limitations. We find that using temporal information helps predicting the ratings, although correlation with the ratings is lower than reported for other corpora. Finally, we show changes in compositionality over time for a selection of compounds.
