        abstract = {Citation graphs visualize citation relationships of publications. Hence citation graphs enable in-depth analysis about the impact of publications to research areas, such that citation graphs have great benefits for systematic reviews about a special field of research. In this contribution, we introduce a tool for automatically generating citation graphs from a set of paper documents, which runs stand-alone or integrated in a systematic reviews application. As systematic reviews often include many papers, we also propose several strategies to reduce the complexity of citation graphs and add additional information for in-depth analysis of the impact of single publications. In addition to citation graphs our tool also visualizes the publication selection process of systematic reviews. The generated graphs and developed strategies are evaluated using different instruments, including an user survey, in which they are rated positively.}

        abstract = {This paper discusses the criteria for usability testing and evaluation of Multimedia e-Learning Management Systems (MEMS). This was achieved through an in-depth analysis and synthesis of literature and presentation of results of a practical application using the University of Zimbabwe MEMS, Towards Student-Centred Integration of Multimedia ELearning, TSIME. Firstly, a critical review, analysis and synthesis of usability testing and evaluation of MEMS was done. That was followed by an in-depth synthesis of the learning theories as the structural basis of MEMS. Major criteria were drawn from MEMS usability, design aspects, institutional dimensions, and learning theories. The derived criteria were merged with the generic usability heuristics producing sixteen TSIME Usability Heuristics, TSIMEUH. Heuristic Evaluation (HE) method was used to test TSIME. The evaluation was carried out for two weeks using three expert evaluators. Twenty-eight usability problems were identified from the study, ten of which were classified as requiring high priority intervention while the rest needed moderate to minimal priority intervention and were solved. The major criteria that emanated from the study were under motivation, ethics and navigation attributes. The key findings indicated that criteria drawn can empower learning and solidify a good learning environment through the use of MEMS. The criteria also embrace a consolidated learning pattern that can be used in global pandemics such as the COVID-19 era by both instructors and learners. The research concluded that learning is embedded in the historical, social and material context and should be improved through interaction and feedback that incorporate the learning theories.}

However, different programming languages have different syntax and semantic rules, and support different programming paradigms and design patterns. Learning a programming language needs many efforts and much practicing in order to master the rules and apply the patterns. Leaning multiple programming languages at the same time, of course, needs more efforts. In this work we develop the concept of multi-game and an e-learning platform called "Multi-Game Platform for Code-Duels" for learning multiple programming languages easily and efficiently. A multi-game is a video game, which consists of several mini-games. Dividing a big game into mini-games reduces the development efforts and implementation complexity. "Builders" is a multi-game developed in our platform consisting of three mini-games. Each mini-game can be solved by implementing a program by learners using different languages. Using our multi-game platform, each mini-game of Builders can be developed easily and played independently of the other mini-games. Finally, a user evaluation over our multi-game platform is performed, where users rate our multi-game approach and platform for learning programming languages very positively.}

        abstract = {This paper relies on findings and theory from both the human-computer interaction and cognitive psychology literatures in order to inquire into the extent to which the halo effect contaminates web interface design assessments. As a human cognitive bias, the halo effect manifests itself when a judge's evaluations of an entity's individual characteristics are negatively or positively distorted by the judge's overall affect toward the entity being judged. These distortions and halo-induced delusions have substantial negative implications for rational decisionmaking and the ability to objectively evaluate businesses, technologies, or other humans, and should hence be a critical consideration for both managers and organizations alike. Here we inquire into the halo effect using a controlled, randomized experiment involving more than 1,200 research subjects. Subjects' preexisting affective states were activated using polarizing issues including abortion rights, immigration policy, and gun control laws. Subjects were then asked to evaluate specific interface characteristics of six different types of websites, the textual content of which either supported or contradicted their preexisting affective beliefs. Comparing subject responses to objective control evaluations revealed strong evidence of halo effect contamination in assessments of web interface design, particularly among men. In light of the results, a theoretical framework integrating elements from cognitive and evolutionary psychology is proposed to explain the origins and purpose of the halo effect.}

To show the effects of the success criteria and their dimensions a survey of 646 participants was conducted. The effects of the criteria and dimensions on IT project success were subsequently studied with structural equation modeling. Because of some inconsistencies within the original model of IT project success a deducted model had to be developed. Some of the success criteria and dimensions had to be rearranged or removed from the original model due to the results of the study. The new model shows that the perception and the results of a project have a significant impact on the success rating of an IT project.}

In the course of the production plant lifecycle, engineers from a variety of disciplines (e.g., mechanics, electronics, automation) need to collaborate in multi-disciplinary settings that are characterized by heterogeneity in terminology, methods, and tools. This collaboration yields a variety of engineering artifacts that need to be linked and integrated, which on the technical level is reflected in the need to integrate heterogeneous data. Semantic Web technologies, in particular ontologybased data integration (OBDI), are promising to tackle this challenge that has attracted strong interest from the engineering research community. This interest has resulted in a growing body of literature that is dispersed across the Semantic Web and Automation System Engineering research communities and has not been systematically reviewed so far. We address this gap with a survey reflecting on OBDI applications in the context of Multi-Disciplinary Engineering Environment (MDEE). To this end, we analyze and compare 23 OBDI applications from both the Semantic Web and the Automation System Engineering research communities. Based on this analysis, we (i) categorize OBDI variants used in MDEE, (ii) identify key problem context characteristics, (iii) compare strengths and limitations of OBDI variants as a function of problem context, and (iv) provide recommendation guidelines for the selection of OBDI variants and technologies for OBDI in MDEE.}

The unique characteristics are a purposeful search of citations for a specified set of publications (of e.g., an author or an institute). Therefore, search strategies will be developed and evaluated in this work in order to reduce the costs for the analysis of documents without citations to the given set of publications. In our experiments, for authors with more than 100 publications about 75 \% of the citations were found. The purposeful strategy examined thereby only 1.5 \% of the 120 million publications of the used data set.}

Various proposals were formulated to model and implement these functions; however, there is no unified approach that can improve the efficiency of software solutions to enable economy of scale. In this paper, we propose a framework that a service supplier can use to manage geo-localized activities. The proposed framework is based on a NoSQL data model and implemented using the MongoDB system. We also discuss the advantages and drawbacks of a NoSQL approach.}

Additionally, it attempts to identify the relevance of the discovered criteria and dimensions with regard to the determination of IT project success. It becomes evident here that the old-fashioned Iron Triangle still plays a leading role, but some long-term strategical criteria, such as value of the project, customer perspective or impact on the organization, have meanwhile caught up or pulled even.}

In the market, data and analysts' knowledge are shared by selling and buying, with reasonably determining the conditions for sharing. People in the market may communicate with each other in order to decide to expose the data as open-source, if the trust of the data provider is expected to be elevated highly due to the contribution to people in the public.

Advanced cross-platform approaches such as MD2, which is based on model-driven development (MDSD) techniques, are a much more powerful yet less mature choice. We discuss business implications of MDSD for apps and introduce MD2 as our proposed solution to fulfill typical requirements. Moreover, we highlight a business-oriented enhancement that further increases MD2's business practicability. We generalize our findings and sketch the path towards more versatile MDSD of apps.}

In this paper, we address this modeling problem experimentally. Firstly, we focus on the relation between thinking time and writing time in handwriting. We observe two types of patterns; one group takes longer time in thinking and shorter in writing, the other takes longer in writing and shorter in thinking. The group having spends longer in writing has shorter time span from one sentence to another than the other group. Backtracking, i.e., the event that  participants return back to their former sheet and modify opinions, is observed more often in the group of longer writing than the other group. In addition, participants in this backtracking group gets higher scores for their ideas on sheets than those in the no-backtracking group. We propose a model of creative thinking by applying Operations of Structure of Intellect. It is inferred that the group of longer writing conducts a series of thinking flow, including divergent thinking, convergent thinking and evaluation. In contrast, the group of longer thinking tends to conduct the two different thinking flow: divergent thinking and evaluation; convergent thinking and evaluation. For making creative ideas, we conduct divergent thinking without evaluation and created a large number of ideas. We conclude that the rotations of divergent thinking, convergent thinking and evaluation increase the frequency of "backtracking" and make the ideas more logical ones.}

        abstract = {The design of cyber-physical systems (CPS) is a promising domain, where the data market is expected to soon penetrate. When engineers focus on only a particular part of data (whether intentionally or not) for establishing a design hypothesis, the design hypothesis may also be supported by data sets in the market. Therefore, the validity of such a design hypothesis cannot be evaluated by the data itself, and can only be accepted by the robustness of the logic behind the design argumentation. Although the validation of the design logic is significant, cognitive aspects (which people have spontaneously) disturb the design argumentation reasoning. Therefore, a design method that overcomes the cognitive aspects is indispensable for the CPS designers. This work proposes a CPS design method using the interaction between logic and data sets with a logic visualization tool, and applies the proposed method to the design of a diagnosis system for semiconductor manufacture. The capability of the proposed method is also discussed and analyzed in this paper.}

Our framework addresses a need of electric utilities for which specific guidance was lacking. We have also uncovered a significant impact of social issues in IT governance, whose depth seems to be missing in the current research.

        abstract = {Social systems are changing so rapidly that it is important for humans to make decisions considering uncertainty. A scenario is information about the series of events/actions, which supports decision makers to take actions and reduce risks. We propose Action Planning for refining simple ideas into practical scenarios (strategic scenarios). Frameworks and items on Action Planning Sheets provide participants with organized constraints, to lead to creative and logical thinking for solving real issues in businesses or daily life. Communication among participants who have preset roles leads the externalization of knowledge. In this study, we set three criteria for evaluating strategic scenarios; novelty, utility, and feasibility, and examine the relationship between externalized knowledge and the evaluation values, in order to consider factors which affect the evaluations. Regarding a word contained in roles and scenarios as the smallest unit of knowledge, we calculate Relativeness between roles and scenarios. The results of our experiment suggest that the lower the relativeness of a strategic scenario, the higher the strategic scenario is evaluated in novelty. In addition, in the evaluation of utility, a scenario satisfying a covert requirement tends to be estimated higher. Moreover, we found the externalization of stakeholders may affect the realization of strategic scenarios.}

In particular, since BPMN 2.0 with a standardized execution semantics allows specifying alternatives for data as well as optional data, identifying missing or unused data systematically is difficult. In this paper, we propose an approach for detecting data-flow errors in BPMN 2.0 process models. We formalize BPMN process models by mapping them to Petri Nets and unfolding the execution semantics regarding data. We define a set of anti-patterns representing data-flow errors of BPMN 2.0 process models. By employing the anti-patterns, our tool performs model checking for the unfolded Petri Nets. The evaluation shows that it detects all data-flow errors identified by hand, and so improves process quality.}

The applications of color science are truly omnipresent, and what impression colors make on human plays a vital role in them. In this paper, we offer the novel approach for color information representation and processing using fuzzy sets and logic theory, which is extremely useful in modeling human impressions. Specifically, we use fuzzy mathematics to partition the gamut of feasible colors in HSI color space based on standard linguistic tags. The proposed method can be useful in various image processing applications involving query processing. We demonstrate its effectivity in the implementation of a framework for the apparel online shopping coordination based on a color scheme. It deserves attention, since there is always some uncertainty inherent in the description of apparels.}

One prominent example of time series are energy consumption records, which might reveal details of the daily routine of a household. Existing privacy approaches for time series, e.g., from the field of trajectory anonymization, assume that every single value of a time series contains sensitive information and reduce the data quality very much. In contrast, we consider time series where it is combinations of tuples that represent personal information. We propose (n; l; k)-anonymity, geared to anonymization of time-series data with minimal information loss, assuming that an adversary may learn a few data points. We propose several heuristics to obtain (n; l; k)-anonymity, and we evaluate our approach both with synthetic and real data. Our experiments confirm that it is sufficient to modify time series only moderately in order to fulfill meaningful privacy requirements.}

It introduces a new construct, Perceived Sociability of Use (PSOU), to explain the use of such computer mediated communication applications. Based on a field study of 113 Facebook users it shows that PSOU in the sense of maintaining social contacts is a significant predictor of Perceived Benefits (PB), Perceived Enjoyment (PE), attitude toward use and intention to use. Inspired by Benbasat and Barki, this paper also attempts to answer questions "what makes the system useful", "what makes the system enjoyable to use" and "what makes the system sociable to use". As a consequence it pays special focus on systems characteristics of IT applications as potential predictors of PSOU, PB and PE, introducing seven such designable qualities (user-to-user interactivity, user identifiability, system quality, information quality, usability, user-to-system interactivity, and aesthetics). The results indicate that especially satisfaction with user-to-user interactivity is a significant determinant of PSOU, and that satisfactions with six of these seven designable qualities have significant paths in the proposed nomological network.}
