Node attributes "in the alternative" (decisionmakers' names)

[CaseLawMiner]

Hello! I am fairly new to this type of research, but I have used Gephi a bit for basic mapping / visualisation. I have searched for an answer and did not find it, so apologies if this this has been covered.

So, I am doing network analysis of case law and I am proceeding as follows. I have two csv files, one with nodes, the other one with edges. The first one has attributes relating to the case, something like:

Code: Select all

Id,Attribute1,Year,Attribute2
CaseA,JurisdictionA,1988,ReproductiveRights

The other is what case cites another and the type of citation, so that would be

Code: Select all

Source,Target,Attribute
Case1,Case2,CitTopicA
Case2,Case3,CitTopicB

Now, what I want to do is to add the name of the individual judges in the cases so as to compare it to the citation patterns. However, there multiple judges. So, how do I go about comparing that? The problem is that I don't know what type of variable that is. If I have:

Code: Select all

CaseA,JurisdictionA,1988,ReproductiveRights,JudgeA,JudgeB,JudgeC

I need to be able to find a correlation with

Code: Select all

CaseB,JurisdictionC,2001,ReproductiveRights,JudgeC,JudgeD,JudgeE

Is this possible?

Thanks a lot!

Hi,
You can use the String List (String [] array) type for that, when importing the spreadsheet.

Just make sure you correctly escape values in CSV with " or the commas inside your judges list won't be parsed correctly.

Code: Select all

Id,Attribute1,Year,Attribute2,Judges
CaseA,JurisdictionA,1988,ReproductiveRights,"JudgeA,JudgeB,JudgeC"

Thank you! That sounds fantastic! Do you mean that if I write

Code: Select all

CaseB,JurisdictionC,2001,ReproductiveRights,"JudgeJohnny,JudgeDonald,JudgeEric"

Gephi will then be able to find a correlation with

Code: Select all

CaseB,JurisdictionC,2001,ReproductiveRights,"JudgeAlice,JudgeBob,JudgeDonald"

?

If so, this solves an enormous amount of problems!

Thanks!

Oh, I think I don't understand, I thought you just wanted to import an attribute as a list of strings.

Anyway you can try it to see if it's what you need.

Let me put it this way: what I want to do is to link decisions decided by the same judges, but in each case there are at least three judges. So what I want to do is find a way for Gephi to see that two cases have been decided by the same judges. One way I can think of is to make Gephi filter it by attributes, but I assume it would be necessary for the same judge to be in the same column for it to work.

In other words, I do not understand if it can do something like that. Let's say I want to find two cases decided by Judge Bob

CaseB,JurisdictionC,2001,ReproductiveRights,JudgeAlice,JudgeBob,JudgeDonald

CaseA,JurisdictionD,2001,ReproductiveRights,JudgeBob,JudgeRobert,JudgeLawrence

Now Judge Bob is in two different columns. Can Gephi filter that?

The alternative would be to have something like:

CaseB,JurisdictionC,2001,ReproductiveRights,"JudgeAlice,JudgeBob,JudgeDonald"
CaseA,JurisdictionD,2001,ReproductiveRights,"JudgeBob,JudgeRobert,JudgeLawrence"

Can Gephi filter this better?

Thanks a lot!

Oh, core Gephi can't automatically find relationships between nodes, but you can try with this plugin: https://gephi.org/plugins/#/plugin/similarity-computer

[CaseLawMiner]

Thank you! This actually sounds quite useful!

Actually, I am also asking another related question: can't I simply do it in the data laboratory? (By searching and, hopefully, finding a way to highlight or display just those nodes?)

Thanks!

[eduramiba]

Yeah, you can do some filtering manually in data lab and filters window.

[CaseLawMiner]

Thank you! This is very useful. Do you have any suggestions about how to go about it? I can search within the data laboratory, but I don't seem to be able to filter the graph based on the search results.

Thanks again!
