The IEEE International Conference on Requirements Engineering (RE) is the premier conference on all aspects of requirements-related research. As in previous years, we continue a long-standing tradition and invited the authors of the best RE papers to submit an extended version to the Requirements Engineering Journal (REJ). This year, we have the pleasure to showcase four papers: three from the main RE research track and one from the industrial innovation track. RE’18, the 26th installment of the RE conference, was held at the Banff Centre for Arts and Creativity in Canada’s Banff National Park, known for its breathtaking mountainous surroundings, wildlife, and hot springs. The conference attracted over 250 researchers, practitioners, educators, and students to present and discuss the most recent research results, innovations, experiences, and concerns in the discipline of requirements engineering. On behalf of all RE’18 attendees, we thank and congratulate the entire organization team, led by the General Chair Guenther Ruhe, for hosting such an outstanding and memorable event. We also thank the reviewers, authors, organizers, volunteers, sponsors, and participants for their contributions and for their commitment to excellence in requirements engineering research and practice. The RE’18 main conference attracted 182 paper submissions, including 90 in the research track, 22 in the industrial innovation track, and 70 in the other tracks reporting on work in progress (RE@Next!, data, doctoral symposiums, posters/ demos, and panels). For the first time at RE, the research track used a double-blind reviewing approach where the authors’ names were unknown to the reviewers. The Program Committee (PC) met in person in Hamburg, Germany, and discussed each paper with at least one positive review. In total, 24 research papers were accepted. The industry papers at RE’18 were renamed Industry Innovation papers to stress the nature and importance of these contributions to the RE community. Each paper was also evaluated by three PC members, with an online discussion led by the Industry Innovation co-chairs: Lionel Briand and Smita Ghaisas. A total of eight papers were finally accepted. The four research papers with the best review scores and explicit support of the PC, together with the best industry innovation paper, were invited to submit an extended version to this special issue of REJ. Four out of five groups of authors accepted the invitation. The extended papers went again through a rigorous review process, albeit single-blind given that the original papers were available and their authors known. Each extension had to be substantial, with over 40% of new material/results. Reviewers’ comments on the original submissions also had to be taken into consideration. Each extended submission had two original and one new reviewer. After several iterations to meet the quality standards of the journal, all four papers were finally accepted. In 2018, the RE conference theme was “Crossing Boundaries and Increasing Impact.” While being focused on requirements engineering, we also aimed to open the door to innovation and new perspectives on the discipline. We believe that RE is inherently multidisciplinary: interfacing problems understanding and solutions design while involving various stakeholders. Yet, the boundaries between academia and industry, as well as those between software engineering and other areas, still deserve more attention. Crossing such boundaries and others between different methods and different application domains, such as automotive or e-commerce, can help increase the impact of RE research and techniques on practitioners’ lives and on society in general. Not only was the theme well reflected in the conference program (e.g., in the excellent keynote presentations of Jane Cleland-Huang, Gail C. Murphy, and Krzysztof Czarnecki), but it is also reflected in the four papers of this special issue. The first paper is “Teaching Requirements Elicitation Interviews: an Empirical Study of Learning from Mistakes,” by Muneera Bano, Didar Zowghi, Alessio Ferrari, Paola * Daniel Amyot damyot@uottawa.ca

社论，特刊 RE 2018

IEEE 国际需求工程会议 (RE) 是有关需求相关研究各个方面的首要会议。与往年一样，我们延续了悠久的传统，并邀请最佳 RE 论文的作者向需求工程期刊 (REJ) 提交扩展版本。今年，我们有幸展示了四篇论文：三篇来自主要可再生能源研究轨道，一篇来自产业创新轨道。RE'18 是 RE 会议的第 26 届，在加拿大班夫国家公园的班夫艺术与创意中心举行，该公园以其令人叹为观止的山区环境、野生动物和温泉而闻名。会议吸引了超过 250 名研究人员、从业人员、教育工作者和学生展示和讨论最新的研究成果、创新、经验、以及需求工程学科的关注点。我们代表所有 RE'18 与会者感谢并祝贺由总主席 Guenther Ruhe 领导的整个组织团队举办了如此出色而令人难忘的活动。我们还要感谢审阅者、作者、组织者、志愿者、赞助商和参与者的贡献以及他们在需求工程研究和实践方面的卓越承诺。RE'18 主要会议吸引了 182 篇论文提交，其中研究方向 90 篇，工业创新方向 22 篇，其他方向 70 篇报告正在进行的工作（RE@Next！、数据、博士研讨会、海报/演示） , 和面板）。在 RE 上，研究轨道首次使用双盲审阅方法，审阅者不知道作者姓名。程序委员会 (PC) 在德国汉堡亲自会面，并讨论了每篇论文至少有一个正面评价。共接收研究论文24篇。RE'18 上的行业论文更名为“行业创新论文”，以强调这些贡献对 RE 社区的性质和重要性。每篇论文还由三位 PC 成员进行评估，并由行业创新联合主席 Lionel Briand 和 Smita Ghaisas 主持在线讨论。最后一共接收了八篇论文。获得最佳评审分数和PC明确支持的四篇研究论文，连同最佳行业创新论文，被邀请向本期REJ特刊提交加长版。五组作者中有四组接受了邀请。扩展论文再次经过严格的审查过程，尽管是单盲的，因为原始论文可用且作者已知。每个扩展都必须是实质性的，超过 40% 的新材料/结果。审稿人对原始提交的评论也必须考虑在内。每个扩展提交都有两名原审稿人和一名新审稿人。经过多次迭代达到期刊质量标准，最终四篇论文全部录用。2018 年，RE 会议的主题是“跨越边界和增加影响”。在专注于需求工程的同时，我们还旨在为该学科的创新和新视角打开大门。我们认为，可再生能源本质上是多学科的：在涉及各种利益相关者的同时，将问题理解和解决方案设计相结合。然而，学术界和工业界的界限，以及软件工程和其他领域之间的那些，仍然值得更多关注。在不同方法和不同应用领域（例如汽车或电子商务）之间跨越这些界限和其他界限，有助于增加可再生能源研究和技术对从业者生活和整个社会的影响。该主题不仅在会议日程中得到了很好的反映（例如，Jane Cleland-Huang、Gail C. Murphy 和 Krzysztof Czarnecki 的出色主题演讲），而且还反映在本期特刊的四篇论文中。第一篇论文是“教学需求启发访谈：从错误中学习的实证研究”，作者：Muneera Bano、Didar Zowghi、Alessio Ferrari、Paola * Daniel Amyot damyot@uottawa.ca 在不同方法和不同应用领域（例如汽车或电子商务）之间跨越这些界限和其他界限，有助于提高可再生能源研究和技术对从业者生活和整个社会的影响。该主题不仅在会议日程中得到了很好的反映（例如，Jane Cleland-Huang、Gail C.
