Due to organic synthesis achievements, the amount of data and knowledge in organic chemistry grows exponentially. Despite the existence of diverse software and information products, there is a need for high-quality intelligent systems that can facilitate the decision-making process in the tasks scientists solve every day. The quality of intelligent system knowledge base defines the overall intelligent system quality. In case of the ontological approach to intelligent system design, the expert forms an application area knowledge base in reliance on the concept system and the structure that the application area ontology model forms. This is due to the semantic constraints of the problem input data. It is impossible to define the input data precisely;however, it is possible to denote a larger set the input data belong to. The article is devoted to the application of the ontological approach for the design and development of the intelligent system, the major task of which is organic compound reaction capacity identification. The use of this approach is driven by the intelligent system requirement analysis. The foreground requirements that involve alternating intelligent system knowledge and metaknowledge and extending intelligent system functionality (by means of adding problem-solvers for new classes of tasks) can be satisfied if the intelligent system architecture considers key features of the knowledge-intensive application domain and is based on its ontology model. © 2019 IEEE.

In the present information age, providing correct information to the query with a limited concept is a challenging task. The modern adaptive Information Retrieval (IR) system is needed to provide valid information. Ontology-based on IR can provide a better solution. Ontology is a perception of shared conceptualization, represented by classes, properties, and objects. Ontology mapping offers a solution to integrate inter-domain knowledge. This paper presents a method for using ontologies to handle inter-domain query in information retrieval. Using ontology in IR for Query Expansion (QE) and document ranking seems to be the ultimate goal. The Multi-Domain Specific Ontology Mapping (MDOM) proposes the concepts derived from ontology for query expansion and information retrieval. The result shows the improvement in terms of better document ranking.

Background: software architecture is a crucial while significantly challenging topic in the computer science curriculum. Although “learning by doing” is widely advocated to address this topic's abstract and fuzzy nature, educators are still facing various difficulties in practice, especially including students' vicious circle of inexperience and the mental model dilemma in experiential learning. Aims: To help break the aforementioned vicious circle and mental model dilemma, this work aims to investigate our educational strategy of using lightweight projects with public and free PaaS resources (1) to help students accumulate architectural experience from the early stage and (2) to facilitate strengthening students' fundamental architecture knowledge. Method: To collect more empirical evidence, we conducted action research on our educational strategy across three undergraduatecurriculum courses for two years. In particular, we employed the Technology Acceptance Model (TAM) to validate how well students received such an educational strategy. Results: The students involved in the relevant coursework generally gave positive feedback with respect to learning theoretical concepts and a set of architectural patterns. Meanwhile, we also observed diverse learning curves for utilizing PaaS resources. Conclusions: Although there still exist PaaS-related limits, our educational strategy can foster students' experiential learning and collaborative learning in fundamental architecture courses. We believe that there are also potentials to extend our work to broader and advanced courses of software architecture.

Machine learning improves the development of self-adaptive systems, i.e., to react to unforeseen situations. However, state-of-the-art smart home platforms lack the ability to integrate machine learning models directly into their knowledge base. While there are machine learning approaches for smart home environments, they are usually not integrated nor represented in the middleware of smart environments. Instead, they rely on data obtained previously and use it in a form prepared for a single use case. To remedy this, our aim is to extend existing middleware platforms to integrate machine learning algorithms as first-class concepts of the knowledge base. To achieve this, we employ relational Reference Attribute Grammars to design and implement an integrated runtime model, where machine learning models can be represented and related to elements of the extended knowledge base, e.g., physical entities, location, users, and activities. Consequently, this enables using a state-of-the-art middleware to build a self-adaptive system, which integrates machine learning algorithms enabling both context-awareness and self-awareness. To showcase the feasibility of our approach, we implemented a small smart home scenario using openHAB as a middleware, in which the system learns the preferences of a user using neural networks.

With the development of information-based and intelligent system of Chinese highway, traffic accident prevention is an important application of road traffic safety research. To solve the safety hazard caused by frequent traffic accidents on highways and improve accident handling efficiency, in this paper, we propose an early warning method for highway traffic accident based on Bayesian network. With the Bayesian network theory and the mutual information theory, the Bayesian network was constructed by combining the traffic accident data and flow data, which can break the limitation problem in which the experts need a large amount of prior knowledge to establish the network structure. The experimental results show that the proposed method has higher accuracy in early warning of accidents. At the same time, the temporal distribution of prediction results is consistent with the peak season. © 2019 Association for Computing Machinery.

software application is heavily being used by today's business operations. However as of the fact, it is no software application in the market can guarantee that it has no software defect escaped during the release. Whenever software application error arises, it can be the cause happened either within the software application layer or any other factor outside the software application layer. The root cause analysis activity becomes more complex in such situation as the analysis activity involves multiple layers. Time consuming is increased to identify the valid error. It leads to the entire analysis duration which can be easily prolonged. This arises the problem statement that, the duration of root cause analysis on software application error carries crucial impact to the service restoration. The objective is to create a logic model to conduct decision making process. This process includes the identification of the root cause in a more accurate manner, and shorten the duration of root cause analysis activity. The design of Analytic Hierarchy Process (AHP) hierarchy will depend on the software application errors and other involved errors found from different layers. These errors become the participants. The participants can be grouped further based on the error categories. Once the hierarchy is constructed, the participants analyze it through a series of pairwise comparisons that derive numerical scales of measurement for the nodes. Then, the priorities are associated with the nodes, and the nodes carry weights of the criteria or alternatives. based on the priority, the valid error and the preferred resolution can be decided. Many past researches in AHP had been conducted, however there is a knowledge gap of AHP in software application error analysis. Therefore, a Prescriptive Analytical Logic Model (PAL) incorporates with AHP into the proposed algorithm is suggested. This logic model would contribute a new knowledge in the area of log file analysis to shorten the tot

After a developer submits code, corresponding test cases arise to ensure the quality of software delivery. Test failures would occur during this period, such as crash, error, and timeout. Since it takes time for developers to resolve them, many duplicate failures will happen during this period. In the delivery practice of SAP HANA, crash triaging is considered as the most timeconsuming task. If duplicate crash failures can be automatically identified, the degree of automation will be significantly enhanced. To find such duplicates, we propose a training-based mathematical model that utilizes component information of SAP HANA to achieve better crash similarity comparison. We implement our approach in a tool named K-Detector (knowledge-based Detector), which is verified by 11,208 samples and performs 0.986 in AUC (Area Under ROC Curve). Furthermore, we apply KDetector to the production environment, and it can save 97% human efforts in crash triage as statistics.

The preventive approach of software security is the basis of what is referred to as secure by design. The principle is to avoid vulnerabilities as soon as the system is designed. Several research work are aimed to this objective. Most of them rely on empirical studies which need a realistic corpus. This corpus holds applications with different vulnerabilities and others without any known vulnerability. To the best of our knowledge, such a security corpus does not exist. In this paper, we present a novel approach based on an automatic annotation process to build a security corpus for real Java applications. Our approach takes advantage of several existing code scanners in order to annotate the corpus. We applied our process of vulnerability annotation on a well-known corpus, namely Qualitas Corpus, from the software engineering research community. We provide the resulting security corpus, namely SecureQualitas, to the research community. The experiments we conducted demonstrate that our approach gives better results than the scanners taken alone.

With agile methodology and international collaboration having become industry standards not only in software engineering, how would we enable students in higher education to gather these experiences? One possible approach presents our intensive course on agile software development, applying games in engineering education, within the framework of a one-week pan-European exchange program. First, we briefly introduce the program that's held twice a year, offering about 60 scientific intensive courses in each session. Topics come from the research fields at the partner institutions and focus on engineering, natural sciences, and mathematics. Roughly 4,000 students from 24 universities in 15 European countries participate in the program annually. Second, we report on the concept and design of our intensive course on agile software development. We apply a flipped classroom setting to acquire the basic knowledge; we use game-based learning for in-class exercises; we foster project-based and collaborative learning for practical implementation. Finally, we outline the project work in our course and share the most inspiring student projects diving into data-driven visualizations and learning analytics. Thus, the participants gain insights into the real-life application of agile project management methods and international collaboration in heterogeneous teams despite the limited course length.

Inconel718 (In718) Nickel based super alloy is widely used in aerospace applications, marine and defensive applications, In most of the cases the products are subjected to different types of loads in their applications. The knowledge of mechanical properties is essential for the mechanical engineer, working with materials. In the current research, the samples are modeled using NX software and fabricated in two different orientations, Horizontal (thickness in z-direction) and Vertical (length in z-direction) by using DMLS process. The fabricated samples are then tested for their tensile strength, compression strength, Impact strength, Hardness, wear resistance and corrosion resistance. The results obtained from both the orientations clearly indicate that the tensile strength, wear resistance, corrosion resistance are high for horizontally fabricated samples and Hardness, Compression strength, Impact resistance are high for vertically fabricated samples.
