Introduction: Although the interview is the most important and widely used requirements elicitation technique, novice engineers do not receive adequate training in Requirements Engineering (RE) courses. Objectives: The goal of the research is to develop an AI-based interview simulator for helping novice requirements engineers in gaining interview skills. Methods: The research is based on the Design Science Methodology for Information Systems. The simulator is the outcome of six cycles; in each cycle, a proof of concept with additional features is created. Each cycle finishes with evaluation and improvement suggestions. Results: The simulator has been tested with students and results have been promising. The interview simulator understands context-free questions, retrieving the right information related to RE concepts such as Tasks, Goals, Users, Benefits, Stakeholders, Constraints, and Integration. Furthermore, the simulator also makes summaries of conversation, answers meta-questions, and questions based on the context. Conclusions: The simulator has received good response from students, they were able to complete the tasks and feedback suggests that simulator will be surely helpful for novice engineers to improve interview skills. Moreover, the interview simulator will be tested in a real RE course in the academic year 2020-2021. Once it proves effective in the classroom, it will be opened to the RE community for free use and improvement.
C eltis australis L. is one of the important plant belong to the family Ulmaceae which is one of the largest family of about 15 genera and 200 species. Celtis occidentalis L. are commonly cultivated for shade purposes in Egyptian gardens (Singh et al., 2006). Celtis australis is a deciduous tree commonly known as the European nettle tree or Mediterranean hackberry. Hackberry fruits are seldom used for nutritional purposes. The nutritional and physicochemical properties, including water, total fiber, protein, Abstract | Celtis australis L. is one of the most important annual plants globally. The current study was conducted to evaluate Celtis australis genotypes through morphological and biochemical characterizations. A total of 80 genotypes were collected from different regions of district Dir and Swat, Khyber Pakhtunkhwa Pakistan, and were characterized for 11 phenotypic traits (4 qualitative and 7 quantitative). A significant diversity was found for leaf length with the range of 4 to 15 cm, leaf width 1 to 7.0 cm, petiole length range from 0.5 to 4.5cm.The internodes length ranged from 0.5cm to 6. The seed length ranged from 4 to 11mm. The 100 seed weight ranged from 7.7 to 48g. Correlation analysis revealed that leaf width was strongly significant with leaf length (0.454**), 100 seed weight with leaf length (0.289**), seed width was also found strongly significant with seed length (0.246*), and 100 seed weight was found significant with seed length (0.236*). On the basis of Cluster analysis, all the genotypes were divided into two linkages and further divided into 7 sub clusters. Every group showed less difference to one another but high variation to other groups. Similarly, in total seed storage proteins, a total of 13 polypeptides bond were found with the total genetic diversity of (0.68%) found in band 1, while in band 2, the variation was 0.63%. A cluster dendogram was constructed for total seed storage proteins and divided 7 sub clusters, where CA1 and CA69 were found the most diverse genotypes. The main aim of this study was to explore morphological variation in order to generate data that could assist in determining the most appropriate tools that are adaptable to various environments.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
