Due to the difficulty of performing repairs during flight, spacecraft is operated according to operational scenarios tested before launch. Operational models, a type of SysML activity diagram, can be used to depict these scenarios. Although it aids in communication between engineers and stakeholders, the activity diagram can rapidly grow rather large. Due to the extensive operational model, it is therefore challenging to review the activity diagram, which could result in serious issues. Therefore, to make operational models easier to evaluate, they should be made concise. This study offers a metamodel that offers stereotypes that can succinctly characterize spacecraft operational scenarios. First, a mind map was used to depict the domain knowledge of spacecraft operations. Second, stereotype metamodel was created by extracting common knowledge from the mind map. Utilizing stereotypes, operational models' size can be decreased;however, crucial review-related data could be lost. Therefore, shrinking stereotypes assures that crucial information would not be lost. Several trials were conducted and showed that the number of elements of operational models with stereotypes, as well as their size, reduced by almost half, compared with the original ones, allowing for a simplified review process and boosting trust in the accuracy of the operational scenarios.

User stories are brief descriptions of a system feature told from a user's point of view. During requirements elicitation, users and analysts co-specify these stories using natural language. A number of approaches have tried to use Natural Language Processing (NLP) techniques to extract different artefacts, such as domain models and conceptual models, and reason about software requirements, including user stories. However, large collections of user story models can be hard to navigate once specified. We extracted different components of user story data, including actors, entities and processes, using NLP techniques and modelled them with graphs. This allows us to organise and link the structures and information in user stories for better analysis by different stakeholders. Our NLP-based automated approach further allows the stakeholders to query the model to view the parts of multiple user stories of interest. This facilitates project development discussions between technical team members, domain experts and users. We evaluated our tool on user story datasets and through a user study. The evaluation of our approach shows an overall precision above 96% and a recall of 100%. The user study with eight participants showed that our querying approach is beneficial in practical contexts.
