Meta-Learning for Phonemic Annotation of Corpora
Veronique Hoste, Walter Daelemans, Erik Tjong Kim Sang +1
We apply rule induction, classifier combination and meta-learning (stacked classifiers) to the problem of bootstrapping high accuracy automatic annotation of corpora with pronuncia…
Applying System Combination to Base Noun Phrase Identification
Erik F. Tjong Kim Sang, Walter Daelemans, Herve Dejean +4
We use seven machine learning algorithms for one task: identifying base noun phrases. The results have been processed by different system combination methods and all of these outpe…
Bootstrapping a Tagged Corpus through Combination of Existing Heterogeneous Taggers
Jakub Zavrel, Walter Daelemans
This paper describes a new method, Combi-bootstrap, to exploit existing taggers and lexical resources for the annotation of corpora with new tagsets. Combi-bootstrap uses existing…
Memory-Based Shallow Parsing
Walter Daelemans, Sabine Buchholz, Jorn Veenstra
We present a memory-based learning (MBL) approach to shallow parsing in which POS tagging, chunking, and identification of syntactic relations are formulated as memory-based module…
Cascaded Grammatical Relation Assignment
Sabine Buchholz, Jorn Veenstra, Walter Daelemans
In this paper we discuss cascaded Memory-Based grammatical relations assignment. In the first stages of the cascade, we find chunks of several types (NP,VP,ADJP,ADVP,PP) and label…
Forgetting Exceptions is Harmful in Language Learning
Walter Daelemans, Antal van den Bosch, Jakub Zavrel
We show that in language learning, contrary to received wisdom, keeping exceptional training instances in memory can be beneficial for generalization accuracy. We investigate this…
