This book is an attempt to establish in the readers the importance of creating interoperable data stores and writing rules for handling this data. It also covers extracts from a few project dissertations and a research funded project that the author had supervised.• Describes the power of ontologies for better data management• Provides an overview of knowledge engineering including ontology engineering, tools and techniques• Provides sample development procedures for creating two domain ontologies.• Depicts the utility of ontological representation in situation awareness• Demonstrates recommendation engine for unconventional emergencies using a hybrid reasoning approach.• The text explains how to make better utilization of resources when emergency strikesGraduates and undergraduates doing courses in artificial intelligence, semantic web and knowledge engineering will find this book beneficial.

Dr. Sarika Jain graduated from Jawaharlal Nehru University (India) in 2001. Her doctorate, awarded in 2011, is in the field of knowledge representation in Artificial Intelligence. She has served in the field of education for over 19 years and is currently in service at the National Institute of Technology, Kurukshetra (Institute of National Importance), India. Dr. Jain has authored or co-authored over 100 publications including books. Her current research interests are knowledge management and analytics, the semantic web, ontological engineering, and intelligent systems. She is currently working toward solving the interoperability problem generated by initiative in the internet of things, big data, and cloud computing.

Dr. Jain has supervised two doctoral scholars (five ongoing) who are now pursuing their postdoctoral studies, one in Spain and the other in Germany. Currently, she is guiding 15 students for their master’s and doctoral research work in the area of knowledge representation. She serves as a reviewer for journals published by IEEE, Elsevier, and Springer. She has been involved as a program- and steering-committee member at many prestigious conferences in India and abroad. She has two funded research projects: one ongoing, funded by CSIR TEQIP- III and worth Rs 2.58 lakhs, and the other completed, funded by the Defense Research and Development Organization, India, and worth Rs 40 lakhs. She applied for a patent in November 2019. Dr. Jain has held various administrative positions at the department and institute level in her career, like head of department, hostel warden, faculty in charge of technical and cultural fests, member of research degree committee, and Center Incharge Examinations.

Dr. Jain has visited the United Kingdom and Singapore to present her research work. She has continuously supervised DAAD interns from different universities of Germany and many interns from India every summer. She works in collaboration with various researchers across the globe, including in Germany, Austria, Australia, Malaysia, the USA, and Romania. She has organized various challenges, conferences, and workshops, including the

National Information Technology Conference (NITC), the Global Initiative of Academic Networks (GIAN) by the Ministry of Human Resource Development, Government of India, the International Conference on Smart Computing and Communication (ICSCC), the International Conference on Advanced Communication and Computational Technology (ICACCT), and International Conference on Eco-Friendly Computing and Communication Systems. She is a member of the Institute of Electrical and Electronics Engineers (IEEE) and the Association for Computing Machinery (ACM) and a Life Member of the Computer Society of India (CSI), the International Association of Engineers (IAENG), and the International Association of Computer Science and Information Technology (IACSIT).

Dr. Jain is highly interested in worldwide collaborations and is seeking scholars and interns for her research group. For more and most updated information, see https://sites.google.com/view/nitkkrsarikajain/.
