Review: Semi-Supervised Learning Methods for Word Sense Disambiguation
2013
IOSR Journal of Computer Engineering
Preserved Fulltext
Word sense disambiguation (WSD) is an open problem of natural language processing, which governs the process of identifying the appropriate sense of a word in a sentence, when the word has multiple meanings ...
In this paper, we discuss the methods of semi-supervised learning and their performance. ...
Yarowsky Bootstrapping Algorithm The Yarowsky algorithm (Yarowsky 1995) was, probably, one of the first and more successful applications of the bootstrapping approach to NLP tasks. ...

We present two algorithms. The first method uses a similar algorithm to that of (Yarowsky 95), with modifications motivated by (Blum and Mitchell 98). ...
The approach gains leverage from natural redundancy in the data: for many named-entity instances both the spelling of the name and the context inwhich it appears are sufficient to determine its type. ...
The Algorithm in (Yarowsky 95) We can now compare this algorithm to that of (Yarowsky 95) . The core of Yarowsky's algorithm is as follows: . . . ...

Partial cognates are pairs of words in two languages that have the same meaning in some but not all contexts. ...
Our approach of identifying cognates and false friends is based on several orthographic similarity measures that we use as features for machine learning classification algorithms. ...
Trying to develop the tool for other languages is also one of our future aims. In order to do this all we need is to plug in lists of cognates and false friends for the corresponding languages. ...
