Opinion mining plays a major role in text mining applications in consumer attitude detection, brand and product positioning, customer relationship management, and market research. These applications led to a new generation of companies and products meant for online market perception, reputation management and online content monitoring. Subjectivity and sentiment analysis focus on private states...

With the rapid growth of computer storage capacities, available data and demand for scoring models both follow an increasing trend, sharper than that of the processing power. However, the main limitation to a wide spread of data mining solutions is the non-increasing availability of skilled data analysts, which play a key role in data preparation and model selection. In this paper we present a ...

The growing abundance of information necessitates the need for appropriate methods for organization and evaluation. Mining data for information and extracting conclusions has been a fertile field of research. However data mining needs methods to preprocess the data. Feature selection is a growing field of interest about selecting proper information from information repositories. The aim of this...

The Research project proposals selection is an challenging task in organizations and companies. When large numbers of research proposals are collected then research Project Selection is a remarkable in all Research funding and Government agencies. The process of Assignment and Selection are unproblematic. The number of proposal submissions are very less. But with mounting in numbers both assign...

Eyes are the windows to the brain and the eye movements are a rich source of information in information processing. The aim of this paper is to select the features with CBFS Feature selection algorithm using eye movements by ElectroOculoGraph (EOG) signals during reading and writing task. The objective is to impart the fundamental functionality to get an extensive understanding of how EOG signa...

The medical data are multidimensional and hundreds of independent features in these high dimensional databases need to be considered and analyzed, for valuable decision-making information in medical prediction. Most data mining methods depend on a set of features that define the behavior of the learning algorithm and directly or indirectly influence the complexity of the resulting models. Hence...

The first step in mining activities is rock excavation in both mine development and production. Constant pressure for cost reduction and creating an improved/safe work environment for personnel has naturally resulted in increased use of mechanical excavation systems in many mining operations. Also, mechanical excavation and mining is more compatible with automation, meaning possibility of reduc...

A major area of current research in data mining is the field of medical diagnosis. In the present study using the Breast cancer Wisconsin data sets, a feature selection algorithm Modified Correlation Rough Set Feature Selection (MCRSFS) predicts both diagnosis and prognosis by comparing several data mining classification algorithms. In the proposed approach, in level 1 of feature selection, fea...

The uncontrolled spread of illegal artisanal small-scale gold mining (ASM), popularly termed “galamsey” in Ghana, has, for decades, impacted adversely upon water bodies, soils, wildlife, human health, and safety. A lack of understanding, however, of the types of galamsey, their operational attributes, and their relative impacts has unfortunately hindered an effective policy response despite num...
