""Principles of Big Data helps readers avoid the common mistakes that endanger all Big Data projects. By stressing simple, fundamental concepts, this book teaches readers how to organize large volumes of complex data, and how to achieve data permanence when the content of the data is constantly changing. General methods for data verification and validation, as specifically applied to Big Data resources, are stressed throughout the book. The book demonstrates how adept analysts can find relationships among data objects held in disparate Big Data resources, when the data objects are endowed with semantic support (i.e., organized in classes of uniquely identified data objects). Readers will learn how their data can be integrated with data from other resources, and how the data extracted from Big Data resources can be used for purposes beyond those imagined by the data creators. . Learn general methods for specifying Big Data in a way that is understandable to humans and to computers. . Avoid the pitfalls in Big D"

"Big data analytics will assist managers in providing an overview of the drivers for introducing big data technology into the organization and for understanding the types of business problems best suited to big data analytics solutions, understanding the value drivers and benefits, strategic planning, developing a pilot, and eventually planning to integrate back into production within the enterprise."

"Data warehousing in the age of the big data will help you and your organization make the most of unstructured data with your existing data warehouse.As big data continues to revolutionize how we use data, it doesn't have to create more confusion. Expert author Krish Krishnan helps you make sense of how big data fits into the world of data warehousing in clear and concise detail. The book is presented in three distinct parts. Part 1 discusses big data, its technologies and use cases from early adopters. Part 2 addresses data warehousing, its shortcomings, and new architecture options, workloads, and integration techniques for Big Data and the data warehouse. Part 3 deals with data governance, data visualization, information life-cycle management, data scientists, and implementing a big data–ready data warehouse. Extensive appendixes include case studies from vendor implementations and a special segment on how we can build a healthcare information factory."

"Stemming merupakan salah satu bagian penting dalam proses penilaian esai secara otomatis. Stemming merupakan proses transformasi suatu kata-kata tertentu menjadi kata dasarnya. Salah satu algoritma stemming yang ada adalah dengan menggunakan persamaan kata, dimana semua kata yang berimbuhan dan istilah yang berbeda untuk satu kata bermakna sama dapat disetarakan bobotnya. Untuk itu proses stemming menggunakan persamaan kata ini akan diimplementasikan pada sistem penilai esai otomatis Simple-O berbasis Generalized Latent Semantic Analysis (GLSA) yang bertujuan untuk meningkatkan ketepatan penilaiannya agar semakin mendekati hasil penilaian oleh manusia. Dari 98 kali pengujian, kinerja GLSA menggunakan proses stemming memberikan hasil yang lebih baik dengan tingkat ketepatan sebanyak 72 kali atau sekitar 73,4% lebih unggul dibandingkan GLSA tanpa proses stemming yang hanya unggul sebanyak 20 kali dari 98 kali percobaan atau dengan presentase sekitar 20,4%. Hal ini menunjukkan bahwa implementasi proses stemming pada Simple-O berbasis GLSA menghasilkan hasil yang lebih baik daripada GLSA tanpa proses stemming.

Stemming is one of the important processes on automatic essay grading. Stemming is a process to transform a word into its root word in order to make essay grader becoming more accurate. One of stemming algorithm that have developed is using word similiarity, where in this algorithm all the prefixed word or the other words that have a similar meaning have an equal weight. This algorithm is implemented on an automatic essay graderbased on Generalized Latent Semantic Analysis (GLSA) called Simple-O in order to match the grade from human raters.

The experiment result shows that from 98 samples GLSA algorithm with the stemming process outperform GLSA without stemming 72 times with the percentage about 73,4%, on the other hand GLSA without stemming only give the better result 20 times with the percentage of 20,4%. This experiments result shows that GLSA based Simple-O using stemming algorithm gives better result than GLSA without stemming process."

"This book contains a wide swath in topics across social networks & data mining. Each chapter contains a comprehensive survey including the key research content on the topic, and the future directions of research in the field. There is a special focus on text embedded with heterogeneous and multimedia data which makes the mining process much more challenging. A number of methods have been designed such as transfer learning and cross-lingual mining for such cases."

"Data merupakan unsur terpenting dalam setiap penelitian dan pendekatan ilmiah. Metodologi sains data digunakan untuk memilah, memilih dan mempersiapkan sejumlah data untuk diproses dan dianalisis. Teknologi big data mampu mengumpulkan data dengan sangat banyak dari berbagai sumber dengan tujuan untuk mendapatkan informasi dengan visualisasi tren atau menyingkapkan pengetahuan dari suatu peristiwa yang terjadi baik dimasa lalu, sekarang, maupun akan datang dengan kecepatan pemrosesan data sangat tinggi. Analisis prediktif memberikan wawasan analisis lebih dalam dan kemunculan machine learning membawa analisis data ke tingkat yang lebih tinggi dengan bantuan teknologi kecerdasan buatan dalam tahap pemrosesan data mentah. Analisis prediktif dan machine learning menghasilkan laporan berbentuk visual untuk pengambil keputusan dan pemangku kepentingan. Berkenaan dengan keamanan siber, big data menjanjikan kesempatan dalam rangka untuk mencegah dan mendeteksi setiap serangan canggih siber dengan memanfaatkan data keamanan internal dan eksternal."

"This book explains and explores the principal techniques of Data Mining, the automatic extraction of implicit and potentially useful information from data, which is increasingly used in commercial, scientific and other application areas. It focuses on classification, association rule mining and clustering.Each topic is clearly explained, with a focus on algorithms not mathematical formalism, and is illustrated by detailed worked examples. The book is written for readers without a strong background in mathematics or statistics and any formulae used are explained in detail.Each chapter has practical exercises to enable readers to check their progress. A full glossary of technical terms used is included.This expanded third edition includes detailed descriptions of algorithms for classifying streaming data, both stationary data, where the underlying model is fixed, and data that is time-dependent, where the underlying model changes from time to time - a phenomenon known as concept drift."
