The classification of verbs in Levin's (1993) English Verb Classes and Alternations: A preliminary Investigation, on the basis of both intuitive semantic grouping and their participation in valence alternations, is often used by the NLP community as evidence of the semantic similarity of verbs (Jing & McKeown 1998; Lapata & Brew 1999; Kohl et al. 1998). In this paper, we compare the Levin classification with the work of the FrameNet project (Fillmore & Baker 2001), where words (not just verbs) are grouped according to the conceptual structures (frames) that underlie them and their combinatorial patterns are inductively derived from corpus evidence. This means that verbs grouped together in FrameNet (FN) might be semantically similar but have different (or no) alternations, and that verbs which share the same alternation might be represented in two different semantic frames.
In this paper, we report on an effort to develop a gold standard for the intensity ordering of subjective adjectives. Rather than pursue a complete order as produced by paying attention to the mean scores of human ratings only, we take into account to what extent assessors consistently rate pairs of adjectives relative to each other. We show that different available automatic methods for producing polar intensity scores produce results that correlate well with our gold standard, and discuss some conceptual questions surrounding the notion of polar intensity.
In this paper, we describe MLSA, a publicly available multi-layered reference corpus for German-language sentiment analysis. The construction of the corpus is based on the manual annotation of 270 German-language sentences considering three different layers of granularity. The sentence-layer annotation, as the most coarse-grained annotation, focuses on aspects of objectivity, subjectivity and the overall polarity of the respective sentences. Layer 2 is concerned with polarity on the word- and phrase-level, annotating both subjective and factual language. The annotations on Layer 3 focus on the expression-level, denoting frames of private states such as objective and direct speech events. These three layers and their respective annotations are intended to be fully independent of each other. At the same time, exploring for and discovering interactions that may exist between different layers should also be possible. The reliability of the respective annotations was assessed using the average pairwise agreement and Fleiss’ multi-rater measures. We believe that MLSA is a beneficial resource for sentiment analysis research, algorithms and applications that focus on the German language.

Recent work suggests that concreteness and imageability play an important role in the meanings of figurative expressions. We investigate this idea in several ways. First, we try to define more precisely the context within which a figurative expression may occur, by parsing a corpus annotated for metaphor. Next, we add both concreteness and imageability as “features” to the parsed metaphor corpus, by marking up words in this corpus using a psycholinguistic database of scores for concreteness and imageability. Finally, we carry out detailed statistical analyses of the augmented version of the original metaphor corpus, cross-matching the features of concreteness and imageability with others in the corpus such as parts of speech and dependency relations, in order to investigate in detail the use of such features in predicting whether a given expression is metaphorical or not.
This paper addresses the task of finding antecedents for locally uninstantiated arguments. To resolve such null instantiations, we develop a weakly supervised approach that investigates and combines a number of linguistically motivated strategies that are inspired by work on semantic role labeling and corefence resolution. The performance of the system is competitive with the current state-of-the-art supervised system.
We provide a unified account of semantic effects observable in attested examples of the German applicative (‘be-’) construction, e.g. Rollstuhlfahrer Poul Sehachsen aus Kopenhagen will den 1997 erschienenen Wegweiser Handiguide Europa fortführen und zusammen mit Movado Berlin berollen (‘Wheelchair user Poul Schacksen from Copenhagen wants to continue the guide ‘Handiguide Europe’, which came out in 1997, and roll Berlin together with Movado.’). We argue that these effects do not come from lexico-semantic operations on ‘input’ verbs, but are instead the products of a reconciliation procedure in which the meaning of the verb is integrated into the event-structure schema denoted by the applicative construction. We analyze the applicative pattern as an argument-structure construction, in terms of Goldberg (1995). We contrast this approach with that of Brinkmann (1997), in which properties associated with the applicative pattern (e.g. omissibility of the theme argument, holistic interpretation of the goal argument, and planar construal of the location argument) are attributed to general semantico-pragmatic principles. We undermine the generality of the principles as stated, and assert that these properties are instead construction-particular. We further argue that the constructional account provides an elegant model of the valence-creation and valence-augmentation functions of the prefix. We describe the constructional semantics as prototype-based: diverse implications of fee-predications, including iteration, transfer, affectedness, intensity and saturation, derive via regular patterns of semantic extension from the topological concept of coverage.
