Sense Discriminative Patterns for Word Sense Disambiguation
نویسندگان
چکیده
Given a target word wi to be disambiguated, we define a class of local contexts for wi such that the sense of wi is univocally determined. We call such local contexts sense discriminative and represent them with sense discriminative (SD) patterns of lexico-syntactic features. We describe an algorithm for the automatic acquisition of minimal SD patterns based on training data in SemCor. We have tested the effectiveness of the approach on a set of 30 highly ambiguous verbs. Results compare favourably with the ones produced by a SVM word sense disambiguation system based on bag of words.

متن کاملPotts Model on the Case Fillers for Word Sense Disambiguation
We propose a new method for word sense disambiguation for verbs. In our method, sense-dependent selectional preference of verbs is obtained through the probabilistic model on the lexical network. The meanfield approximation is employed to compute the state of the lexical network. The outcome of the computation is used as features for discriminative classifiers. The method is evaluated on the da...

Word sense disambiguation is the task of identifying the correct sense for the word in a given context among a finite set of possible sense. In this paper a model for farsi word sense disambiguation is presented. The model use two group of features: first, all word and stop words around target word and topic models as second features. We extract topics from a farsi corpus with Latent Dirichlet ...
متن کاملIRST-BP: Preposition Disambiguation based on Chain Clarifying Relationships Contexts
We are going to present a technique of preposition disambiguation based on sense discriminative patterns, which are acquired using a variant of Angluin’s algorithm. They represent the essential information extracted from a particular type of local contexts we call Chain Clarifying Relationship contexts. The data set and the results we present are from the Semeval task, WSD of Preposition (Litko...
متن کاملContext-aware Discriminative Phrase Selection for Statistical Machine Translation
In this work we revise the application of discriminative learning to the problem of phrase selection in Statistical Machine Translation. Inspired by common techniques used in Word Sense Disambiguation, we train classifiers based on local context to predict possible phrase translations. Our work extends that of Vickrey et al. (2005) in two main aspects. First, we move from word translation to ph...
