SSMG

SSMG (SDG-based Semantic Metrics Generator ) is a tool for extracting semantic metrics.

SDG-based Semantic Metric

Semantic Metric	Description
Dependent Count (DC)	Number of files that semantically depends on the file.
Sum of Dependent Weight (SDW)	Sum of the semantic weight of the edges formed by fileand the files that semantically depend on it.
Average of Dependency Weight (ADW)	Average of the semantic weight of the edges formed by file and the files that semantically depend on it: ADW=SDW/DC.
Longest Dependency Path(LDP)	Number of files involved in the longest path of file in the semantic dependency graph.
Impact Space File Count (ISF)	Number of files involved in file’s impact space.
Sum of Files’ Weight (SFW)	Sum of similarity weights between file and the other files involved in its impact space.
Average of Files’ Weight (AFW)	Average of similarity weights between file and the other files inits impact space .AFW=SFW/ISF
Impact Space Weight (ISW)	Sum of the weights of all edges in the sub graph (i.e. the impact space).
Average Weight of Impact Space (AWIS)	Average weight of file’s impact space: AWIS=ISWf/n, where n is the number of edges in the impact space.
Sum of Semantic Similarity (SSS)	Sum of the semantic similarities between the file and other files in the same project.
Average of Semantic Similarity (ASS)	Average of the semantic similarities between the file and other files in the same project.

Usage

1)How to set up environment.

• you should set up Java environment.(jdk1.8)
• you should set up Python3.0 environment.(64 bit)
• you should set up understand environment.(64 bit)

2)How to use code.

before compile the source code,you should set Program parameters: < projectName_Write > < projectName > < readString > < writeString > < udb_path > < Write_path >

• < projectName_Write >. The folder for storing data created by the project name, for example: projectName_Write + "_data".
• < ** projectName** >. The name of the project.
• < filename.csv >. Project file name exported with [understand]. (https://scitools.com/).
• < readString >. Storage path of project file name.
• < writeString >.Storage path of exported semantic indicators
• < udb_path >. The path of the UDB generated by the project import [understand] (https://scitools.com/).
• < Write_path >.The storage path of the intermediate file generated by the program.

Please be sure to use files in the same format as the example, and ensure that they are in the same order, otherwise the results may be inaccurate.

Example

before run this project, you should Compile Configurations and set Program parameter:

• projectName_Write = "xerces1.2".
• projectName = "xerces-1.2.0-src".
• readString = Project name file path parameter.
• writeString = Semantic metrics file path parameter.
• udb_path = UDB path parameters.
• Write_path=Intermediate file path parameter.

then run the project, You will get the semantic metrics file of this project as shown below:https://github.com/SDGSemantic/SDG_Semanticcode/blob/main/xerces1.2_filename_metric.csv
