A brief survey on some research related issues
A presentation of some hints and advices on how to conduct a MSc Research Dissertation
Missed Issues (but not less important):
How to write literature review?
How to write Dissertation?
![Page 24: MSc Dissertation in a Nutshell - Philadelphia University › it › cs › msc › cs_msc_dissertation_in... · 2014-04-27 · Expected MSc Outcomes Some Research Related Issues MSc](https://reader033.vdocuments.site/reader033/viewer/2022050715/5f0ea10f7e708231d44028c7/html5/thumbnails/24.jpg)
Research Goal
"The research goal of the thesis is to enhance BP Model
Repository technology for large business model collections in a
relevant aspect that has received little attention so far“ [5]
![Page 25: MSc Dissertation in a Nutshell - Philadelphia University › it › cs › msc › cs_msc_dissertation_in... · 2014-04-27 · Expected MSc Outcomes Some Research Related Issues MSc](https://reader033.vdocuments.site/reader033/viewer/2022050715/5f0ea10f7e708231d44028c7/html5/thumbnails/25.jpg)
Sub-goal 1: Analyzing the state of the art of the BP Model
Repository technology to identify an unsolved aspect, i.e.,
efficient process retrieval.[5]
Sub-goal 2: Elaborating, implementing, and evaluating
efficient process retrieval. .[5]
Sub-goal 3: Evaluating the addition of efficient process
retrieval to the state of the art of the BP Model Repository
technology. .[5]
![Page 26: MSc Dissertation in a Nutshell - Philadelphia University › it › cs › msc › cs_msc_dissertation_in... · 2014-04-27 · Expected MSc Outcomes Some Research Related Issues MSc](https://reader033.vdocuments.site/reader033/viewer/2022050715/5f0ea10f7e708231d44028c7/html5/thumbnails/26.jpg)
The following questions are to be answered .[5]
.
� Question 1: What functionality is supported by existing BP Model Repositories?
� Question 2: Why is efficient process retrieval the aspect to be enhanced?
� Question 3: What techniques have been proposed to perform process retrieval?
� Question 4: How to enhance the efficiency of process retrieval?
� Question 5: How to integrate the proposed technique with process retrieval?
� Question 6: How to implement a prototype for the proposed process retrieval
techniques?
� Question 7: How to evaluate the efficiency of the proposed process retrieval
techniques?
� Question 8: What is the contribution of the proposed techniques to the state
of the art of BP Model Repository technology?
