Automatically Determining the Semantic Gradation of German Adjectives
نویسندگان
چکیده
The semantics of gradable adjectives, in particular their order with respect to one another on a given scale, are not sufficiently represented in lexical resources such as wordnets. Thus, it is not clear whether superb expresses the quality of “goodness” equally, more, or less strongly than excellent or great. Sheinman and Tokunaga (2009) determine the relative gradation of English adjectives by applying lexical-semantic patterns that hold between members of pairs of similar descriptive adjectives to corpus searches. The patterns identify one member of such pairs as the one that expresses a stronger, or more intense, degree of the property denoted by the scale than the other member. By iteratively applying these patterns to a set of adjectives, Sheinman and Tokunaga (2009) arrive at a uniform score for each adjective that allows them to place it at an appropriate point on a scale. We extend the AdjScales method (Sheinman and Tokunaga 2009) to some frequent and salient German adjectives to test its crosslingual robustness. Our work has consequences for automatic text understanding and generation, lexicography and language pedagogy.

Exploring the value space of attributes: Unsupervised bidirectional clustering of adjectives in German
The paper presents an iterative bidirectional clustering of adjectives and nouns based on a cooccurrence matrix. The clustering method combines a Vector Space Models (VSM) and the results of a Latent Dirichlet Allocation (LDA), whose results are merged in each iterative step. The aim is to derive a clustering of German adjectives that reflects latent semantic classes of adjectives, and that can...
متن کاملConstructional Intensifying Adjectives in Italian
Grading is a primary cognitive operation that has an important expressive function. Information on degree is grammatically relevant and constitutes what Lazard (2006) calls a primary domain of grammaticalization: According to typological studies (Cuzzolin & Lehmann, 2004), many languages of the world have in fact at their disposal multiple grammatical devices to express gradation. In Italian, t...
متن کاملPredicting the Semantic Orientation of Adjectives
We identify and validate from a large corpus constraints from conjunctions on the positive or negative semantic orientation of the conjoined adjectives. A log-linear regression model uses these constraints to predict whether conjoined adjectives are of same or different orientations, achieving 82% accuracy in this task when each conjunction is considered independently. Combining the constraints...
