Collecting and Investigating Features of Human Semantic Ratings and Resources

Developing computational models to predict meaning components of words and multiword expressions typically goes hand in hand with creating or using reliable lexical resources as gold standards for formative intrinsic evaluation. Not much work however pays attention to whether and how much both the gold standards and the prediction models vary according to the properties of the targets within the lexical resources, and potential skewness hinders us from a generalised assessment of the models.

In this talk, I suggest a novel route to assess the interactions between properties of targets in lexical-semantic datasets and human ratings on target-semantic variables, based on a study on English and German noun compounds such as „climate change“ and „crocodile tears“ in English, and „Ahornblatt“ (maple leaf) and „Fliegenpilz“ (toadstool) in German. I will first introduce (1) a novel collection of compositionality ratings for 1,099 German noun compounds, where we asked the human judges to provide compound and constituent properties (such as paraphrases, meaning contributions, hypernymy relations, and concreteness) before judging the compositionality; and (2) a series of analyses on rating distributions and interactions with compound and constituent properties for our novel collection as well as previous gold standard resources in English (Reddy et al., 2011; Cordeiro et al., 2019) and German (Schulte im Walde et al., 2013; 2016). Following the analyses I will then discuss on a meta level to what extent one should aim for an even distribution of human ratings across the pre-specified scale, and to what extent one should take into account properties of targets when creating a novel resource and when using a resource for evaluation.
