We present extensive evaluations comparing the performance of taxonomy-based and corpus-based approaches on SimLex999. The results confirm our hypothesis that taxonomy-based approaches are more suitable to identify similarity. We introduce two new measures of evaluation that show that all measures perform well on a coarse-grained evaluation and that it is not always clear which approach is most...

The long term goal of this research is to develop a program able to produce an automatic segmentation and categorization of textual sequences into discourse types. In this preliminary contribution, we present the construction of an algorithm which takes a segmented text as input and attempts to produce a categorization of sequences, such as narrative, argumentative, descriptive and so on. Also,...

Expectations about the correlation of cue phrases, the duration of unfilled pauses and the structuring of spoken discourse are framed in light of Grosz and Sidner’s theory of discourse and are tested for a directions-giving dialogue. The results suggest that cue phrase and discourse structuring tasks may align, and show a correlation for pause length and some of the modifications that speakers ...

This paper focuses on the interpretation of metaphor in discourse. We build on previous work [1] in which we provide a formalization in a computationally-oriented formal semantic framework of a set of mappings that we claim are required for the interpretation of map-transcending metaphor. Such mappings are domain-independent and are identified as invariant adjuncts to any conceptual metaphor. I...

Consider an interoretive device that in some manner keeps track of individuals that have been mentioned iu a discourse and what has been said about them. One feature any such device must have is to he able to recognize wPen a novel individual aopears in so~e sentence. For examole, in Drocessin~ sentence (1), it N~st recognize that the NP a car refers to some yet unmentioned object, which in the...

This paper is concerned with a hierarchical representation of the convex relation algebra, which is a computationally tractable subset of Allen’s interval calculus [1, 11]. The hierarchy of convex relations is used to determine the minimal point relation constraints which hold between the end points of the intervals. Nine convex relations are proven to be special, because they introduce new con...

A corpus of spontaneous route descriptions was collected from 8 speakers (5 males and 3 females). The corpus was labelled according to the ToBI standard and a discourse analysis was completed. Four discourse tour acts were identified and these were found to occur mainly in non-embedded linear sequences. In general, the intonation of each route description was characterised by a single intonatio...

The paper introduces a possibility of new research offered by a multi-dimensional annotation of the Prague Dependency Treebank. It focuses on exploitation of the annotation of coreference for the annotation of discourse relations expressed by multiword expressions. It tries to find which aspect interlinks these linguistic areas and how we can use this interplay in automatic searching for Czech ...
