    Text classification (TC) is an important foundation of information retrieval and text mining. The main task of a TC is to predict the text‟s class according to the type of tag given in advance. Most TC algorithms used terms in representing the document which does not consider the relations among the terms. These algorithms represent documents in a space where every word is assumed to be a dimension. As a result such representations generate high dimensionality which gives a negative effect on the classification performance. The objectives of this thesis are to formulate algorithms for classifying text by creating suitable feature vector and reducing the dimension of data which will enhance the classification accuracy. This research combines the ontology and text representation for classification by developing five algorithms. The first and second algorithms namely Concept Feature Vector (CFV) and Structure Feature Vector (SFV), create feature vector to represent the document. The third algorithm is the Ontology Based Text Classification (OBTC) and is designed to reduce the dimensionality of training sets. The fourth and fifth algorithms, Concept Feature Vector_Text Classification (CFV_TC) and Structure Feature Vector_Text Classification (SFV_TC) classify the document to its related set of classes. These proposed algorithms were tested on five different scientific paper datasets downloaded from different digital libraries and repositories. Experimental obtained from the proposed algorithm, CFV_TC and SFV_TC shown better average results in terms of precision, recall, f-measure and accuracy compared against SVM and RSS approaches. The work in this study contributes to exploring the related document in information retrieval and text mining research by using ontology in TC

    Prediction of Banks Financial Distress

    In this research we conduct a comprehensive review on the existing literature of prediction techniques that have been used to assist on prediction of the bank distress. We categorized the review results on the groups depending on the prediction techniques method, our categorization started by firstly using time factors of the founded literature, so we mark the literature founded in the period (1990-2010) as history of prediction techniques, and after this period until 2013 as recent prediction techniques and then presented the strengths and weaknesses of both. We came out by the fact that there was no specific type fit with all bank distress issue although we found that intelligent hybrid techniques considered the most candidates methods in term of accuracy and reputatio

    Barah payu dara adalah penyakit yang paling banyak meragut nyawa kaum hawa. Kadar sembuh dari penyakit ini boleh ditingkaykan jika ia dapat dikesan secara awal. Pengesahan awal penyakit ini dapat dilakukan melalui ujian mamografi yang terbukti keberkesanannya. Survival rates for breast cancer patients may be increased when the disease is detected in its earliest stage through mammography. A thorough assessment during breast screening would also include clinical, physical examination and ultrasound. The implementation of mass screening would result in increased caseloads for radiologists which would incur chances of improper diagnosis

    MODEL PREDIKSI KEBANGKRUTAN BERBASIS NEURAL NETWORK DAN PARTICLE SWARM OPTIMIZATION

    Kebangkrutan suatu perusahaan dan bank dapat mempengaruhi sistem perekonomian. Karena itulah, pihak-pihak seperti: kreditor, auditor, pemegang saham dan pihak manajemen perusahaan itu sendiri memiliki kepentingan untuk mengetahui kondisi suatu perusahaan yang berhubungan dengan kebangkrutan. Dalam penelitian ini dikembangkan beberapa model klasifikasi untuk memprediksi kebangkrutan suatu perusahaan. Model dikembangkan berdasarkan metode yang berbasis ANN (Voted Perceptron, Stochastic Gradient Descent dan Multilayer Perceptron) dengan metode PSO. Metode-metode yang berbasis ANN bertugas sebagai klasifier dan PSO bertugas sebagai pemilih fitur dan penentu parameter-parameter (learning rate dan epoch) optimal model. Dari hasil ujicoba dapat disimpulkan bahwa model yang menggabungkan ANN dengan PSO terbukti memiliki performa yang cukup baik, yaitu sekitar 72-75%. Performa terbaik dicapai oleh model Stochastic Gradient Descent+PSO, yaitu sebesar 75% dengan jumlah fitur sebanyak 7 fitur. Dengan adanya model prediksi dengan performa yang baik, diharapkan pihak memiliki gambaran yang lebih baik tentang perusahaan yang sedang ditangani. Gambaran tersebut akan membantu pihak-pihak yang berkepentingan dalam mengambil keputusan

    Supply chain risk management practice in Malaysian automotive industry

    Organizations are experiencing increasing supply chain risks especially due to new business trends such as globalization and offshoring. For that reason, supply chain risk management is required to manage those risks effectively. Although there is a voluminous academic research on descriptive and conceptual model of supply chain risk management, evidences which describe the implementation of supply chain risk management in industry are limited. Therefore, the purpose of this research is to explore the implementation of supply chain risk management among Malaysian small and medium automotive companies. This study also explores the enablers to supply chain risk management implementation and barriers that impede this practice. Case study method was employed at three companies which were selected through purposeful sampling. By using thematic analysis, the data was analyzed and interpreted. The research results indicated that all three companies were heading towards more formal supply chain risk management implementation. Although the companies managed the supply chain risks based on TS16949 standard and company formal procedures, the tools used in the supply chain risk management, risk communication, training and risk responsibility were yet to be completely formalized. Pressure from customers and top management emerged as the primary enablers to such implementation. This study also revealed that barriers rooted from companies internal such as the lack of knowledge impeded the case companies from advancing their supply chain risk management implementation. The findings of this study offer a description of supply chain risk management implementation for organizations

    Intelligent optimization is based on the mechanism of computational intelligence to refine a suitable feature model, design an effective optimization algorithm, and then to obtain an optimal or satisfactory solution to a complex problem. Intelligent algorithms are key tools to ensure global optimization quality, fast optimization efficiency and robust optimization performance. Intelligent optimization algorithms have been studied by many researchers, leading to improvements in the performance of algorithms such as the evolutionary algorithm, whale optimization algorithm, differential evolution algorithm, and particle swarm optimization. Studies in this arena have also resulted in breakthroughs in solving complex problems including the green shop scheduling problem, the severe nonlinear problem in one-dimensional geodesic electromagnetic inversion, error and bug finding problem in software, the 0-1 backpack problem, traveler problem, and logistics distribution center siting problem. The editors are confident that this book can open a new avenue for further improvement and discoveries in the area of intelligent algorithms. The book is a valuable resource for researchers interested in understanding the principles and design of intelligent algorithms
