EFFECTIVENESS OF N-GRAM FAST MATCH FOR QUERY-BY-HUMMING SYSTEMS
N-gram Fast match Query-by-Humming
2013/6/28
To achieve a good balance between matching accuracy and computation efficiency is a key challenge for Query-by-Humming(QBH) system. In this paper, we propose an approach of n-gram based fast match. Ou...
A PHRASE-LEVEL PIECEWISE LINEAR SCALING ALGORITHM FOR MELODY MATCH IN QUERY-BY-HUMMING SYSTEMS
Phrase-level Piecewise Linear Scaling Query-by-Humming
2013/6/28
The Query-by-Humming (QBH) system allows users to retrieve songs by singing/humming. In this paper we propose a phrase-level piecewise linear scaling algorithm for melody match. Musical phrase boundar...

ImageCLEF 2008 Query Extension Techniques
2010/12/17
In this paper, we present our solutions for the WikipediaMM task at ImageCLEF 2008. The aim of this task is to investigate effective retrieval approaches in the context of a large-scale and heterogene...
An Efficient Data Dissemination Scheme for Nearest Neighbour Query Processing
An Efficient Data Dissemination Scheme Nearest Neighbour Query Processing
2014/3/12
Location dependent information services (LDISs) produce answers to queries according to the location of the client issuing the query. In LDIS, techniques such as caching, prefetching and broadcasting ...
