Culinary is one of the favorite businesses today. The number of considerations to choose a restaurant or place to visit becomes one of the factors that is difficult to determine the restaurant or place to eat. To get the desired place to eat advice, one needs a recommendation system. Decisions made by the recommendation system can be used as a reference to determine the choice of restaurants. One method that can be used to build a recommendation system is Case Based Reasoning. The Case Based Reasoning (CBR) method mimics human ability to solve a problem or cases. The retrieval process is the most important stage, because at this stage the search for a solution for a new case is carried out. The study used the K-Nearest Neighbor method to find closeness between new cases and case bases. With the selection of features used as domains in the system, the results of recommendations presented can be more suggestive and accurate. The system successfully provides complex recommendations based on the type and type of food entered by the user. Based on blackbox testing, the system has features that can be used and function properly according to the purpose of creating the system.

Abstract One of the most significant issues in applying case-based reasoning (CBR) to mechanical design is to integrate previously unrelated design plans towards the solution of a new design problem. The total design solution (the design plan structure) can be composed of both retrieved and dynamically generated design plans. The retrieved design plans must be mapped to fit the new design context, and the entire design plan structure must be evaluated. An architecture utilizing opportunistic problem solving in a blackboard environment is used to map and evaluate the design plan structure effectively and successfuly. The architecture has several assets when integrated into a CBR environment. First, the maximum amount of information related to the design is generated before any of the mapping problems are addressed. Second, mapping is preformed as just another action toward the evaluation of the design plan. Lastly, the architecture supports the inclusion of memory elements from the knowledge base in the design plan structure. The architecture is implemented using the GBB system. The architecture is part of a newly developed CBR System called DEJAVU. The paper describes DEJAVU and the architecture. An example is also included to illustrate the use of DEJAVU to solve engineering design problems.

Case-Based Reasoning (CBR) arose out of research into cognitive science, most prominently that of Roger Schank and his students at Yale University, during the period 1977–1993. CBR may be defined as a model of reasoning that incorporates problem solving, understanding, and learning, and integrates all of them with memory processes. It focuses on the human problem solving approach such as how people learn new skills and generates solutions about new situations based on their past experience. Similar mechanisms to humans who intelligently adapt their experience for learning, CBR replicates the processes by considering experiences as a set of old cases and problems to be solved as new cases. To arrive at the conclusions, it uses four types of processes, which are retrieve, reuse, revise, and retain. These processes involve some basic tasks such as clustering and classification of cases, case selection and generation, case indexing and learning, measuring case similarity, case retrieval and inference, reasoning, rule adaptation, and mining to generate the solutions. This chapter provides the basic idea of case-based reasoning and a few typical applications. The chapter, which is unique in character, will be useful to researchers in computer science, electrical engineering, system science, and information technology. Researchers and practitioners in industry and R&D laboratories working in such fields as system design, control, pattern recognition, data mining, vision, and machine intelligence will benefit.

Intelligent computing techniques have a paramount importance to the treatment of cybersecurity incidents. In such Artificial Intelligence (AI) context, while most of the algorithms explored in the cybersecurity domain aim to present solutions to intrusion detection problems, these algorithms seldom approach the correction procedures that are explored in the resolution of cybersecurity incident problems that already took place. In practice, knowledge regarding cybersecurity resolution data and procedures is being under-used in the development of intelligent cybersecurity systems, sometimes even lost and not used at all. In this context, this work proposes the Case-based Cybersecurity Incident Resolution System (CCIRS), a system that implements an approach to integrate case-based reasoning (CBR) techniques and the IODEF standard in order to retain concrete problem-solving experiences of cybersecurity incident resolution to be reused in the resolution of new incidents. Different types of experimental results so far obtained with the CCIRS show that information security knowledge can be retained with our approach in a reusable memory improving the resolution of new cybersecurity problems.

AbstractThis study focuses on e orts to solve the problems of the low abil- ity students in solving di culties in learning Indonesian language as a subject ma er. The objective of this research is directed at ef- forts of explaining the in uence of Case-based Reasoning (CBR) in the learning towards the students’ problem-solving abilities. The method is a quasi-experimental research focusing on students of MA (Madrasah Aliyah or Islamic Senior High School) in one of the districts in West Java, where the learning in the control class using the Problem Based Learning (PBL). The research showed that the students’ problem-solving abilities by using CBR model is 44% in the high interpretation and by 56% in the moderate interpretation. Whereas the learning using the PBL model is 28% in the high inter- pretation, 56% in the medium interpretation, and 16% in the low interpretation. The value obtained through testing the hypothesis is z-score = -3089 smaller than z-table = -1.64. It means that Ho is refused and Ha is accepted. It further means that there is a sig- ni cant di erence between the problem-solving ability of students of using CBR model in learning and the students using PBL model in learning. The conclusion of this study indicates that the use of CBR model (designed for the study) has proved to give an e ect to the problem-solving skills of students learning Indonesian subject. AbstrakPenelitian ini memfokuskan pada upaya pemecahan per- masalahan mengenai rendahnya kemampuan siswa dalam memecahkan kesulitan-kesulitan ketika mempelajari materi pelajaran Bahasa Indonesia. Tujuan penelitian ini diarah- kan pada upaya menjelaskan pengaruh Case-Based Reasoning (CBR) dalam pembelajaran terhadap kemampuan pemeca- han masalah siswa. Metode penelitian adalah kuasi eksperi- men dengan objek penelitian adalah siswa MA di salah satu kabupaten di Jawa Barat, di mana pembelajaran yang diguna- kan oleh kelas kontrol adalah Pembelajaran Berbasis Masalah (PBL). Hasil penelitian menunjukkan bahwa kemampuan pe- mecahan masalah siswa dengan menggunakan model pembe- lajaran CBR sebesar 44% dalam interpretasi tinggi dan sebe- sar 56% dalam interpretasi sedang. Sedangkan pembelajaran menggunakan model pembelajaran PBL sebesar 28% dalam interpretasi tinggi, sebesar 56% dalam interpretasi sedang dan 16% dalam interpretasi rendah. Sementara berdasarkan hasil uji hipotesis diperoleh nilai zhitung = -3.089 lebih kecil dari ztabel = -1.64. Hasil pengujian ini menunjukan bahwa Ho ditolak atau Ha diterima, artinya ada perbedaan secara signifikan antara kemampuan pemecahan masalah siswa yang menggunakan model pembelajaran CBR dan siswa yang menggunakan model pembelajaran PBL. Simpulan penelitian ini menunjukkan bahwa penggunaan CBR yang dirancang selama penelitian ternyata terbukti memberikan pengaruh terhadap kemampuan pemecahan masalah oleh siswa
