Thank you. I did what you suggested and the following report showed on the terminal window. Is this because of too much article data? Exception: java.lang.OutOfMemoryError thrown from the UncaughtExceptionHandler in thread "Thread-0" Exception: java.lang.OutOfMemoryError thrown from the UncaughtExceptionHandler in thread "Connection evictor"

Hi Dr. Chen, thank you in advance for your help! I downloaded the adjacency matrix and i put it in MATLAB to try to obtain the same values of betweness centrality of citespace but the standar function gives me very high values and i found out that is possible to normalized to get values between 0 and 1, but i keep failing to get the same values citespace is calculating, there is another step i must consider?, theres another method to calculated betweness centrality? Example: n = number of nodes bc...

Thanks for your response. In your example of the matrix, there are some values (0.4714045226573944, 0.8660253882408142, etc.) this numbers represents the value of betweeness centrality or its another value? Thank you in advance

An adjacency matrix is represented in two files when you export it from CiteSpace. For example, if you have a 561-node network, you will get two files: network561x561.txt and network561x561Labels.txt. Depending on what you need, most of the information is accessible through the interactive visualization in CiteSpace. Of course, you can do whatever you need with these exported files. Node names are in the labels file, like this, i.e., 561 lines: SHAH B, 1997, SUDAAN USERS MANUAL, V0, P0 IMM NAT SERV,...

CR = Cited References. Here is what it looks like. It is essential if you choose References as the Note Type.

The issue with the Scopus author has been resolved in the Advanced version 6.3.R3. Should be available in the next Basic version soon.

Do you have a screenshot of the first few lines of the exceptions? I suspect it may be caused by some irregularities in the data. If the problem remains, email me more details along with the dataset, I will take a close look.
-
Dear Professor I have a doubt about the values of the adjacency matrix, I saw that the values are between 0 and 1, is this something like the weight between nodes? Do you have a paper where this values are explained? Thank you in advance.

You should try with the csv version of downloaded bibliobraphic data from Scopus. The RIS file has some issues while converting, while the csv one work fine.

Respected Sir, I have been facing the same issue even with the updated version 6.3R2. I have tried both options: modifying the 'citespace.alias' file manually and through the GUI, but nothing seem to work. I hope this issue will be resolved soon.

Dear Professor Chen, Thank you for your prompt reply. According to your point, I changed all privilege of user/chunlingyu/.citespace folder to "read&write", and error of pic2 seemed to be solved. However, I still cannot get my concept tree. The errors now are in two cases: 1. If I select phrases from titles, error would be pic9. A file named etswos0.txt was created in user/chunlingyu/.citespace folder at the same time. 2. If I select phrases from titles and abstract, the errors would be pic4-->ok-->pic5-->ok-->pic3....

Your pic2 shows the problem: SQL Query Error: OS errno 13 - Permission denied It tries to create a file under /Users/chunlingyu/.citespace but permission was denied.

For your information, I searched resolutions by myself and have done the following two things. 1. create etc/my.cnf file and the 'secure_file_priv' error seemed to be solved.

I tried to solve the "OS errno 13: permission denied" error in pic2, with running terminal command shown in pic8.

Dear Professor Chen, Hi. I am encounting with a problem of MySQL database connection. The Citespace version is 6.3.1, and MySQL version is 8.0.36. The computer system is macOS Monterey version 12.4. I finished the co-citation cluster analysis with Citespace and want to further study the none phrase concept tree, but when I click Data->Import/Export->MySQL->Database, it says "A problem encountered when attempting to onnect your MySQL at localhost" (pic1). Then I click "update my login credentials"...

Mojtaba Hosseini posted a comment on ticket #50
Dear Chen The exact issue is that I cannot download the new version in that website as we have two icons as below: demo.6.2.R7.mov (239 MB) and CiteSpace-6.2.7.msi (135 MB) But the first one (demo) is active and you can click on it to download , but the second one which is the new version is not active and it is impossible to download it . So please let me know how can I do that in any ways, as I really lost the time during two weeks I am waiting for the tickets. Thanks a lot Mojtaba

I have some issues about upgrade new version and other issues
-
Dear Mojtaba, You should be able to download the new Advanced version from citespace.podia.com using the same way as you did last time. Generally speaking, the newer version should be more reliable and accurate. Discrepancies between different versions may be due to improved processing capabilities of the newer version as well as possible changes of the default settings. You can also leave your comments on the citespace.podia.com site.

Dear all I used "all in one" to cluster the map and filter the top 5 clusters. Based on the table, I find that the words "machine learning" are both in cluster#0 and cluster#2, but there is no overlap between these two clusters. I consider that these 2 clusters share the same node(machine learning), so these two clusters should have a little overlay. I kindly ask anyone who knows the reason to answer me. Thank you very much.

hello Mr Chen I have a problem with files converted from scopus directly to the latest citespace version. Viewing cited journal shows incomprehensible codes such as CW ,ET AL, numbers like 1,2,11. I'll send you the screenshots. Conversion is still a problem. Can I have a wos type format for the conversion I would be very grateful.

Thanks for drawing my attention. Let me check.

It is nothing unusual to have nodes with 0 betweenness centrality. It is perfectly fine. Check the definition of betweenness centrality.

Dear Professor Chen, When I use CiteSpace 6.2.R6 for authors co-citation analysis (WOS data), ANONYMOUS becomes the largest node in the results. I considered hiding this node, but it involves some very highly cited articles. Using other versions didn't solve the problem. The core issue: the authors of several articles are not recognized because Citespace recognizes some letters (such as A and U) as ANONYMOUS, as shown below. But the original data is complete. How to solve this problem? I sincerely...

Open the CSV file in Notepad++. If you see UFT-8-BOM at the bottom right corner, remove the BOM as follows: Go to the Encoding menu, select UTF-8 and save the file.

I'm trying to remove that but I don't understand how to remove that using text editor, do you mind to help me remove the BOM or convert that so I can operate it with this amazing program. I'm still new user here by using the (basic) version. Thank you🙏
-
At the beginning of your CSV file, there is "", which is known as a Byte Order Mark (BOM). See the attached image. 6.2.R6 (Advanced) released today (11/26/2023) can take care of this programmatically, but you can mannually remove it with a text editor.

Hello, I've the same problem. I don't know I've tried to follow the instruction for converting Scopus database into Wos (.csv -> tab-delimited -> WoS) but the result of the conversion is 0 kb when I checked the java script it says missing line... Can you help me to solve this? What should I do in the future? Fyi I use the updated version (at least till 27 Nov 23). Thank you so much

You probably missed the step to convert the CSV to a tab-delimited format before running the CSV converter. Attached is the converted and duplicates removed file.

This is downloaded from Scopus and it does not include references. Thank you.

You are right.

Use the All in One function and adjust the Threshold under the Node Labels (By Cluster). This will show labels of top 2 nodes from each cluster. Most likely your top 10 will appear in several clusters.

If Scopus is your source, use the CSV export. Do not use the RIS export for now.

Use the CSV export instead from Scopus. Then convert it in CiteSpace. Currently, the RIS export from Scopus seems broken.

Dear professor: I tried to get the top 10 nodes to be marked, but because the upper threshold limit is only 200, there are too many nodes with a count number greater than 200 in my data set so the result is a little bit cluttered.
