Identifying Cognates by Phonetic and Semantic Similarity
نویسنده
چکیده
I present a method of identifying cognates in the vocabularies of related languages. I show that a measure of phonetic similarity based on multivalued features performs better than “orthographic” measures, such as the Longest Common Subsequence Ratio (LCSR) or Dice’s coefficient. I introduce a procedure for estimating semantic similarity of glosses that employs keyword selection and WordNet. Tests performed on vocabularies of four Algonquian languages indicate that the method is capable of discovering on average nearly 75% percent of cognates at

Evaluation Of Several Phonetic Similarity Algorithms On The Task Of Cognate Identification
We investigate the problem of measuring phonetic similarity, focusing on the identification of cognates, words of the same origin in different languages. We compare representatives of two principal approaches to computing phonetic similarity: manually-designed metrics, and learning algorithms. In particular, we consider a stochastic transducer, a Pair HMM, several DBN models, and two constructe...
متن کاملCross-Language Distributions of High Frequency and Phonetically Similar Cognates
The coinciding form and meaning similarity of cognates, e.g. 'flamme' (French), 'Flamme' (German), 'vlam' (Dutch), meaning 'flame' in English, facilitates learning of additional languages. The cross-language frequency and similarity distributions of cognates vary according to evolutionary change and language contact. We compare frequency and orthographic (O), phonetic (P), and semantic similari...
متن کاملA Persian-English Cross-Linguistic Dataset for Research on the Visual Processing of Cognates and Noncognates
Finding out which lexico-semantic features of cognates are critical in cross-language studies and comparing these features with noncognates helps researchers to decide which features to control in studies with cognates. Normative databases provide necessary information for this purpose. Such resources are lacking in the Persian language. We created a dataset and determined norms for the essenti...
متن کاملMultilingual lexical resources to detect cognates in non-aligned texts
The identification of cognates between two distinct languages has recently started to attract the attention of NLP research, but there has been little research into using semantic evidence to detect cognates. The approach presented in this paper aims to detect English-French cognates within monolingual texts (texts that are not accompanied by aligned translated equivalents), by integrating word...
متن کاملIdentifying Cognate Sets Across Dictionaries of Related Languages
We present a system for identifying cognate sets across dictionaries of related languages. The likelihood of a cognate relationship is calculated on the basis of a rich set of features that capture both phonetic and semantic similarity, as well as the presence of regular sound correspondences. The similarity scores are used to cluster words from different languages that may originate from a com...
