Network Analysis (2) Practice Using igraph and Gephi
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/vCIES2020_Network-Analysis
and the script and data files are in the "igraph" folder.

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. This lecture is designed for beginners to learn from concept and theory to a practical method of the network data analysis with software tools. There are two lecture videos for this workshop.

Thank you! I can use it to explain Network to my high school students.
How can iassign Shapes to Node Types
Great explanation! you made it crystal clear
You are Great❤
Very nice lecture for introduction to network analysis. Thank you!
Thank you 😊
Such an excellent explanation! It was so helpful. Thank you! :)
Hi, are you able to offer a one on one training on SNA and gephi?
Thank you so much!
Thank you so much! You explained so clearly. It was extremely helpful! :)
This was so clearly explained. Helped me a lot. Thank you so much!
Complicated topic mande simple. Thank you
Thank you Sir. The lecture was quite insightful!
thank you! This has been very helpful
Thank you for the amazing video and well organized content
Thank you sooo much for the video, it is well organized, easy to understand and to the point, I wish I could give more than one like for this video, thanks a lot
thank you so much, you explained three 2h lectures in one short video
This is so valuable. Thank you
This saved my day, thank you !
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.
thank u really very useful sir, i need more videos regarding social network analysis.
thank you
can I give you 1000 thumbs up? thank you. this was really informative.
The lectures are very nice. Nice work
I have a question, when those nodes have coordinates, how can I add that attribute to the nodes???
Just wondering if you found a solution for this?
Thank you so much! Really appreciate the quick intro :)
Great tutorial for network analysis, thank you very much. Could you pls share your powerpoint?
جيد
This lecture was really good, really learned a lot. Can you also create network analysis video intermediate and advanced level
Great explanation , thanks !!
Great explanation, best tutorial ever!
많은 도움이 되었습니다. 진심으로 감사합니다.
도움이 되었다니 다행입니다. 감사합니다
Thank you so much for this video!!! Are there any lectures on the bipartite network?
답글 주셔서 감사드립니다. Bipartite network는 저도 개인적으로 매우 흥미로워하는 주제인데 별도의 강의는 저도 본적이 없네요. 제가 나중에 더 공부하면 강의 정리해서 한번 올려보겠습니다.
By far the best video on network analysis! 감사합니다!
Such great help for me… 😭 I sent a message via LinkedIn, I hope you don’t mind.
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.
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?
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.
Finally a clear introduction to network analysis!!!!
Hey, Thanks for the informative video, I cannot find any code in your Github page
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.
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.
@@byoung-gyugong7007 That would be great!
Thank you for making these great workshop videos! May I ask what's your recommendation for any textbook about social network analysis with R?
Thanks for your comment and interest. I haven’t seen any of the books for SNA with R programming. I rather recommend textbooks or tutorials addressing general network analysis with R such as ‘Statistical network analysis with igraoh’ by Gabor Csardi. You can freely download this tutorial book in the internet.
@@byoung-gyugong7007 cool, thank you so much for this info!
