You are presented with multiple paper abstracts, alongside the associated literature review and chapter titles. Given the provided information, you are going to do a literature review. Please generate a coherent literature review that synthesizes the content, draws connections between different works, highlights major findings, and identifies any gaps in the existing research.

Literature Review Title: A systematic literature review on activity recognition with context-awareness techniques for mitigation of disasters 
Chapter Title:  Focus of the research 
1. Abstract of Cited Paper (BIB001):  Context: Model-driven code generation is being increasingly applied to enhance software development from perspectives of maintainability, extensibility and reusability. However, aspect-oriented code generation from models is an area that is currently underdeveloped. Objective: In this study we provide a survey of existing research on aspect-oriented modeling and code generation to discover current work and identify needs for future research. Method: A systematic mapping study was performed to find relevant studies. Classification schemes have been defined and the 65 selected primary studies have been classified on the basis of research focus, contribution type and research type. Results: The papers of solution proposal research type are in a majority. All together aspect-oriented modeling appears being the most focused area divided into modeling notations and process (36%) and model composition and interaction management (26%). The majority of contributions are methods. Conclusion: Aspect-oriented modeling and composition mechanisms have been significantly discussed in existing literature while more research is needed in the area of model-driven code generation. Furthermore, we have observed that previous research has frequently focused on proposing solutions and thus there is need for research that validates and evaluates the existing proposals in order to provide firm foundations for aspect-oriented model-driven code generation.

Literature Review:
The selected studies were divided into five research focus as shown in Figure 6 (a) based on the research topics considered in this paper. The keywording method described in software engineering BIB001 in combination with BIB002 were studied and apply to the research domain under consideration in line with issues, relevant area and problems. The problems include application, context acquisition, sensing, and modelling (context interaction), AR prediction, context reasoning and DM.
