The Empirical Software Engineering Research Group (ESERG) at Bournemouth University, UK have been involved with the use of estimation by analogy techniques (case-based reasoning) for since the mid 1990s. ANGEL and archANGEL are software tools that support this approach to prediction.
ArchANGEL provides substancial increases in functionality and performance over ANGEL Plus and has backward compatibility with ANGEL Plus data files.
System requirements:
ArchANGEL is written in Java and requires the 1.4 Java runtime environment (download
here).
Installation instructions: readme.txt
Note: This software is in a beta realease and currently has only limited help information. It is made available on an "as is" basis without warranty and on the understanding that it will not be made available to other parties without these conditions being attached. ArchANGEL may not be sold or included within any other system that is used for commercial purposes.
The full release version of ArchANGEL (including complete help documentation) will be available here shortly.
Background on the ANGEL project.
ANGELPlus 2.02 is still available if required.
There are still a number of known problems.
1. Any predicted feature must be an integer. This can be addressed by simply changing units, for example from person-months to person-hours
2. The import facility requires the source data to be a formatted as a text file as follows:
begin_source
FeatureName1,FeatureName2, ...,n
FeatureValue1,FeatureValue2, ...,n
end_source
The dataset template must then be manually edited to describe each feature type, its priority (if in doubt NORMAL)and to switch the features on/off. Use the space bar to toggle through admissable values.
