Sentence fusion is a text-to-text (revision-like) generation task which takes related sentences as input and merges these into a single output sentence. In this paper we describe our ongoing work on developing a sentence fusion module for Dutch. We propose a generalized version of alignment which not only indicates which words and phrases should be aligned(More)
We train a decision tree inducer (CART) and a memory-based classifier (MBL) on predicting prosodic pitch accents and breaks in Dutch text, on the basis of shallow , easy-to-compute features. We train the algorithms on both tasks individually and on the two tasks simultaneously. The parameters of both algorithms and the selection of features are optimized(More)
In this paper, we investigate the usefulness of normalized alignment of dependency trees for entailment prediction. Overall, our approach yields an accuracy of 60% on the RTE2 test set, which is a significant improvement over the baseline. Results vary substantially across the different subsets, with a peak performance on the summarization data. We conclude(More)
We propose to analyse semantic similarity in comparable text by matching syntactic trees and labeling the alignments according to one of five semantic similarity relations. We present a Memory-based Graph Matcher (MBGM) that performs both tasks simultaneously as a combination of exhaustive pairwise classification using a memory-based learner, followed by(More)
We describe an ongoing effort to build a large-scale parallel/comparable monolingual treebank for Dutch of 1 million words, where nodes of dependency trees are aligned and labeled according to a limited set of semantic similarity relations. We address alignment of sentences and dependency trees, both manual and automatic. We introduce new annotation tools,(More)
This paper * describes an eye tracking experiment to study the processing of diphone synthesis, unit selection synthesis, and human speech taking segmental and suprasegmental speech quality into account. The results showed that both factors influenced the processing of human and synthetic speech, and confirmed that eye tracking is a promising albeit time(More)
One of the strategies that question-answering (QA) systems may follow to retain users' trust is to express the level of uncertainty attached to answers they provide. Multimodal QA systems offer the opportunity to express this uncertainty through other than linguistic means. On the basis of evidence from the literature, it is argued that uncertainty is in(More)
