This video is for the Network Analysis and Visualization Workshop organized at the Virtual Annual Conference of Comparative and International Education Society 2020 (vCIES 2020) in April 2020.
There are two lecture videos for this workshop. The first video includes the theory part of my lecture and the second video file is for the practice of the igraph and Gephi with the data files.
This second session is for practice with analysis software, igraph in R and Gephi.
You can find and download the data files and R script from this GitHub address:
github.com/Arizonagong/vCIES2...
and the script and data files are in the "igraph" folder.

Thank you very much for uploading this video. I was trying to learn about igraph and gephi for week and finally found the best practice.

Great tutorial for network analysis, thank you very much. Could you pls share your powerpoint?

Thank you so much for this video!!! Are there any lectures on the bipartite network?

@byoung-gyugong7007 3 года назад

답글 주셔서 감사드립니다. Bipartite network는 저도 개인적으로 매우 흥미로워하는 주제인데 별도의 강의는 저도 본적이 없네요. 제가 나중에 더 공부하면 강의 정리해서 한번 올려보겠습니다.

thank you; I hope you share an intermediate or advanced network analysis metrics video

Thank you for your comment. I hope to be able to upload new video this spring. I am thinking of presenting other show cases of igraph functions and visualization techniques.

Thanks for the video but I encountered some errors from the stage of creating an igraph object from the dataframes like below. Warning message: In igraph_opt("return.vs.es") : internal error -3 in R_decompress1 Do you know why? if so, any suggestion?

@byoung-gyugong7007 3 года назад

Hello Seize. I have no idea how that happened. Would you please let me know which command line created that warning message? And if it is just a warning not an error message it would be just fine.

Hi Sir... Its a good tutorial for the analysis of the Social Network. I am following the theory and the practical part. I have the following question which arise when you created Adjacency Matrix (undirected) at the video tutorial at 26:15 (you can find the scenario when the video is at 26: 15 sec) 1) The first column consists of the Student_ID. Does the first row consists of the Student_ID as well ? In Adjacncy matrix we only have node at the first column and the rest matrix consists of edges only. 2) why the adjacency matrix was symmetric i.e. I can understand no value at the diagonal but please define the same matrix above and below the diagonal element. 3) Sir I am not been able to get the Plotting (can not detect the clustering and community as the major of the area is covered with black color) as much clear and attractive as yours in the tutorial. Can you shed some light on this sir? kindly elaborate ASAP.

I have a question, when those nodes have coordinates, how can I add that attribute to the nodes???

@nimakh5176 Год назад

Just wondering if you found a solution for this?

@behnam2534 3 года назад

Hey, Thanks for the informative video, I cannot find any code in your Github page

@byoung-gyugong7007 3 года назад

Thanks for your feedback, Behnam. The files are in the "igraph" folder in the page. Please click the folder icon and then you will find first two data files and last Rscript file.
