First, a context based model (CPRM) established by using labeled-LDA (Labeled Latent Dirichlet Allocation) algorithm. interest point are improved mining information in unstructured text. Then, framework on convolutional neural network (IPR...

The invisible hands of peer reviewers play a determining role in the eventual fate of submissions to international English-medium journals. This study builds on the assumption that non-native researchers and prospective academic authors may find the whole strive for publication, and more specifically, the tough review process, less threatening if they are aware of journal reviewers’ expectation...

industrial-scale r&d it projects depend on many sub-technologies which need to be understood and have their risks analysed before the project can begin for their success. when planning such an industrial-scale project, the list of technologies and the associations of these technologies with each other is often complex and form a network. discovery of this network of technologies is time con...

theoretical review of ‘mining pit lakes’ indicates that like natural lakes such lakes display a huge diversity. they are typically in a non-equilibrium state with respect to their surroundings. hence, at the decommissioning phase of mining operation a detailed technical study are required on different aspects of such created water bodies considering its morphometry, geology, hydrology, water qu...

In the recent years the area of data mining has experienced a considerable demand for technologies to extract knowledge from large and complex data sources. There is a substantial commercial interest as well as research activities in the area that aim to develop new and improved approaches for extracting information, relationships, and patterns from datasets. Artificial Neural Networks (NN) are...

With the rapid increase of number Internet users and amount online comment data, a large referable information samples are provided for data mining technology. As technical application mining, text sentiment classification can be widely used in public opinion management, marketing, other fields. In this study, combination approach to SVM (support vector machine) IPSO (improved particle swarm op...

ABSTRAC : Medical professionals need a reliable prediction methodology to diagnose hematological data comments. There are large quantities of information about patients and their medical conditions. Generally, data mining (sometimes called data or knowledge discovery) is the process of analyzing data from different perspectives and summarizing it into useful information. Data mining software is...

mining and metallurgical projects are among those that require the most sizeable invest-ments undertaken in iran. one target of the current development plan and the ministry of mines and industries has been to attract foreign investment in mining projects. a survey of world-class mining companies was conducted to determine their expectations and in order to recommend a frame work for iran aimed...

Workers’ compensation and disability management in the hazardous occupations of mining and construction are ongoing concerns for employers, employees, insurers and Governments. Rising insurance costs, options of self insurance models, highly competitive tendering, legislative rigidities, and escalating costs of compensation, have contributed to industry practices for injured workers that are dr...

Sierra Leone is blessed with abundant natural resources but yet prone to environmental degradation due to the mining operations. Most often, the mining communities are faced with social tensions, as a result of the possible trade-off between the expected employment impact and the cost of mining operations to the environment. Over the past decades, the contribution of the mining sector to the de...
