hi from my heart, thank you so much for the k-anonymity-simulator it helps me too much but I face this problem the program cant read the file.txt (like public static final String WIKI_VOTE_FILE = "/src/resources/DataSets/wiki-Vote.txt";) the console system show this for me 2137 [main] DEBUG org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor - Autowiring by type from bean name 'main.java.App.Main' to bean named 'AppFrame' 2140 [main] ERROR main.java.App.View.AppFrame - java.lang.NullPointerException 2204 [Thread-1] DEBUG main.java.App.Datasets.DataSetController - Start load DataSet:Facebook circles Exception in thread "Thread-1" java.lang.NullPointerException at java.io.Reader.(Reader.java:78) at java.io.InputStreamReader.(InputStreamReader.java:72) at main.java.App.Common.Utils.FileUtil.loadDataSet(FileUtil.java:25) at main.java.App.Datasets.DataSetController.loadDataSet(DataSetController.java:69) at main.java.App.Common.UITasks.DataSetLoaderTask$1.run(DataSetLoaderTask.java:30) at java.lang.Thread.run(Thread.java:745)

I don't have a function to read a file in this project. And, by the way, this repo is only for a class demo. The implementation has major issues, which do not completely simulate the k-anonymity idea. Thank you for your question, but please do not use this project in a serious case unless you find some useful pieces of codes.

No,Thank you for this project It give me an idea about how implementing the k-anonymous algorithm I will try to improve it I am a master student and I need such open source to implement my thesis idea But I have few questions, please answer it if you have time -If you publish a paper or make a report about this tools Please send me a capy 🤗

-from what I read before, the k-symmestry algorithms anonymize the network structure (do not anonymize the location of the node). I mean your implementation for the k-symmestry do the same thing, is what I understand right???

Hopefully, I do not bother you Thank you so much for everything you did for me

Hi, @SaraMkh

We have a report for the project. Final+Project+Report.docx It's been a year. I don't remember all details. Use it with your own risk.

Let me know if you have more questions.

Thank you.
