Comparing Knowledge Sources for Nominal Anaphora Resolution
We compare two ways of obtaining lexical knowledge for antecedent selection in other-anaphora and definite noun phrase coreference. Specifically, we compare an algorithm that relies on links encoded in the manually created lexical hierarchy WordNet and an algorithm that mines corpora by means of shallow lexico-semantic patterns. As corpora we use the British National Corpus (BNC), as well as th...
متن کاملUsing the Web for Nominal Anaphora Resolution
We present a novel method for resolving non-pronominal anaphora. Instead of using handcrafted lexical resources, we search the Web with shallow patterns which can be predetermined for the type of anaphoric phenomenon. In experiments for other-anaphora and bridging, our shallow, almost knowledge-free and unsupervised method achieves state-ofthe-art results.
متن کاملAcquiring Lexical Knowledge for Anaphora Resolution
The lack of adequate bases of commonsense or even lexical knowledge is perhaps the main obstacle to the development of highperformance, robust tools for semantic interpretation. It is also generally accepted that, notwithstanding the increasing availability in recent years of substantial hand-coded lexical resources such as WordNet and EuroWordNet, addressing the commonsense knowledge bottlenec...
متن کاملQuantification and Nominal Anaphora
Quantification and nominal anaphora is a rich and complex area of research, which has attracked many people; especially since the development of dynamic semantics in the early eigthies. One way to obtain a systematic view on this field, is to focus on the quantificational resources employed to interpret anaphoric relationships. In this article, I will develop such a view as far as first-order q...
متن کاملResolving Portuguese Nominal Anaphora
This paper presents two approaches to Portuguese anaphor resolution, one based on a morpho-syntactic information and other on semantic features. We present a corpus based evaluation, focusing especially on anaphoric definite descriptions, which includes direct, indirect and associative anaphors.
