MapReduce Algorithm for Location Recommendation by Using Area Skyline Query

A Method for Location Recommendation via Skyline Query Tolerant to Noisy Geo-referenced Data

This work presents a method to perform a location recommendation based on multiple criteria even when there is noise in the coordinates. More specifically, the skyline query is adapted to handle this noise by modeling the errors of geo-referenced points with an appropriate probability distribution and modifying the traditional dominance criterion used by that technique. The method is applied to...

Efficient Selection of Various k-Objects for a Keyword Query Based on MapReduce Skyline Algorithm

fault location in power distribution networks using matching algorithm

چکیده رساله/پایان نامه : تاکنون روش‏های متعددی در ارتباط با مکان یابی خطا در شبکه انتقال ارائه شده است. استفاده مستقیم از این روش‏ها در شبکه توزیع به دلایلی همچون وجود انشعاب‏های متعدد، غیر یکنواختی فیدرها (خطوط کابلی، خطوط هوایی، سطح مقطع متفاوت انشعاب ها و تنه اصلی فیدر)، نامتعادلی (عدم جابجا شدگی خطوط، بارهای تک‏فاز و سه فاز)، ثابت نبودن بار و اندازه گیری مقادیر ولتاژ و جریان فقط در ابتدای...

Parallel Computation of Skyline and Reverse Skyline Queries Using MapReduce

The skyline operator and its variants such as dynamic skyline and reverse skyline operators have attracted considerable attention recently due to their broad applications. However, computations of such operators are challenging today since there is an increasing trend of applications to deal with big data. For such data-intensive applications, the MapReduce framework has been widely used recent...

Processing of Probabilistic Skyline Queries Using MapReduce

There has been an increased growth in a number of applications that naturally generate large volumes of uncertain data. By the advent of such applications, the support of advanced analysis queries such as the skyline and its variant operators for big uncertain data has become important. In this paper, we propose the effective parallel algorithms using MapReduce to process the probabilistic skyl...
