Introduction – Software Requirements Specifications(SRS) 軟體需求說明書  a description of a software system to be developed, laying out functional and non-functional requirements.  found early in Software Development Life Cycle → pay less to fix problems

 an artificial intelligence technique that reasons by remembering and recalling previously experienced cases.  how people generate new solutions to newly encountered problems.  CBR cycle are Retrieve （ 擷取 ）, Reuse （ 再使用 ）, Revise （ 修改 ）, and Retain （ 保留 ）. Introduction – case-based reasoning(CBR) 案例式推理

Introduction – case-based reasoning(CBR)

Introduction – Artificial neural network 類神經網路 SUM I1 I2 I3 In ……. W1 W2 W3 Wn f t Input 1 Input 2 Input 3 Input 4 Output

Introduction – Artificial neural network  good in handling unstructured problems  parallel nature  automatically learns  can be implemented in almost any application

Research objectives  case-based reasoning + artificial neural network  construct a framework of the proposed approach.

Related and previous works Fuzzy ANN

The proposed framework  Step 1 - Retrieve: Retrieve the most similar case or group of cases. （ ANN ）  Step 2 - Reuse: Reuse the information, knowledge, and solution in that case to solve the problem at hand if there is a perfect match.  Step 3 - Revise: Modify and adapt the most similar case or group of cases as appropriate if a perfect match is not found.  Step 4 - Retain: Retain or save the new experience or case for future retrievals and problem solving, and the case base is updated by saving the newly learned case.

The proposed framework

Conclusion  提供一個輔助方法找出類似或一樣的軟體說明書 ， 以期 預先探知可能發生的問題 。
