Ambiguity

The Context-Free backbone of some natural language ana- lyzers produces all possible CF parses as some kind of shared forest, from which a single tree is to be chosen by …...

We report here on our experiments with POST (Part of Speech Tagger) to address problems of ambiguity and of understanding unknown words. Part of speech tagging, per se, is a …...

Telegraphic messages with numerous instances of omis- sion pose a new challenge to parsing in that a sen- tence with omission causes a higher degree of ambi6u- ity than a …...

Concerning different approaches to auto- matic PoS tagging: EngCG-2, a constraint- based morphological tagger, is compared in a double-blind test with a state-of-the-art statistical tagger on a common disambigua- tion …...

Ambiguous propositions are analyzed in a type system where disambiguation is effected during assembly (i.e. by coer- cion). Ambiguity is introduced through a layer of types that are underspecified relative …...

Ambiguity is the fundamental property of natural language. Perhaps, the most bur- densome case of ambiguity manifests itself on the syntactic level of analysis. In order to face up to …...

Covering ambiguity is one of the two basic types of ambiguities in Chinese word segmentation. We regard its resolution as equivalent to word sense disambiguation, and make use of the …...

This paper presents an unsupervised al- gorithm which automatically discovers word senses from text. The algorithm is based on a graph model representing words and relationships between them. Sense clusters …...

Recent studies into Web retrieval have shown that word sense disambiguation can increase retrieval effectiveness. How- ever, it remains unclear as to the mini- mum disambiguation accuracy required and the …...

. There have been heated debates on whether tense markers in Korean are inflectional affixes or syntactic words. One of the strongest pieces of evidence for the latter position comes …...

. This paper examines some syntactic and semantic properties of the negative construction V+bo NP (VbN) in Taiwanese Southern Min (TSM). It finds out that there are ambiguities between an …...

AbstractMost of the research on the extraction of idiomatic multiword expressions (MWEs) focused on the acquisition of MWE types. In the present work we investigate whether a text instance of …...

We present the first algorithms to automat- ically identify explicit discourse connectives and the relations they signal for Arabic text. First we show that, for Arabic news, most adjacent sentences …...

AbstractThis paper presents a novel gold standard of German noun-noun compounds (Ghost-NN) including 868 compounds annotated with corpus frequencies of the compounds and their constituents, productivity and ambiguity of the …...

AbstractThis paper describes CCG/AMR, a novel grammar for semantic parsing of Abstract Meaning Representations. CCG/AMR equips Combinatory Categorial Grammar derivations with graph semantics by assigning each CCG combinator an interpretation …...

AbstractSemantic annotation tasks contain ambiguity and vagueness and require varying degrees of world knowledge. Disagreement is an important indication of these phenomena. Most traditional evaluation methods, however, critically hinge upon …...

AbstractGiven a sentence “Abby told Brittney that she upset Courtney”, one would struggle to understand who “she” refers to, and ask for clarification. However, if the word “upset” were replaced …...

AbstractArgument maps structure discourse into nodes in a tree with each node being an argument that supports or opposes its parent argument. This format is more comprehensible and less redundant …...
