Dear Kingsley:

From what I have understood by reading the messages in the forums and by browsing through the site is that you have implemented a version of Apriori in C#. However I have not managed to find the file neither on the web site nor on any of the posts in the forum. Clearly it is also not located in thes forum where the source code is supposed to be.

So if my assumptions are correct, can you help me find the source code of your Apriori implementation in this site? If it is not, is it possible to send it through email?

I have downloaded the .NET_Framework project, however I cannot find something the can be used inside, except from the data class, correct me if I am wrong. Also I cannot run the project since I get to the same error message about cryptography (?) that another user in this forum got as well with no response about the solution.

I have also downloaded VBDMNaiveBayes and VBDMOneRule which is very good work, however not in the association rule area which is the field of my research.

Thanks in advance Kingsley. I am waiting for your reply to tell me if you have an Apriori implementation and if yes, how can I get it, of course if you are willing to share it.

Thanks in advance

Hi :

The existing Apriori Algorithm is a commercial version. I have a new beta version of the algorithm implemenation in C#.

The cryptography error can be taken care of by remarking the line that refers to the missing key in AssembliInfo.vb (AssemblyKeyFile)

We are close to launching a new site dedicated to Data Mining (2 weeks) and we will be providing more information about data mining algorithm implementation at the new site

Dear Kingsley Tagbo:

Thanks for the reply. One more question: Does the commercial version of Apriori come with the C#.NET code? If yes how much does it cost? I have seen a link before a couple of months where the cost was $30. Is this still the same?

Thanks in advance

Angelo

Hi :

That particular version has been retired. I have re-written the component and the new version is in Beta Release.

I would post a release note when it is no longer in Beta version.

Thanks

Advance Thanks

I have released the algorithm with all the source code. You can download it from this forum

Hi! i have downloaded the Apriori implementation in C# and am getting the error " Cryptographic failure while signing assembly ". Plz let me know how can i remove this error, cuz  i do not understand what it is saying.

Thanx in advance

Hi:

Just comment out the line [assembly: AssemblyKeyFile("")] in the file named AssemblyInfo.cs.

Thanks

Hi,

 

I have downloaded the code and It has run with a XML archive but in the part where I write the database connection string and push ANALYZE I obtain an error message. I dont know what I should do.

Please Help me.

hai ,
           i am an MCA student .i need this apriori alogorithm in vb.u said that it was released by u in this forum.i am not able to find that code.can u please send it to my mail?.its urgent,pls help me.my mail id
jeykarthi@yahoo.com

***** HELP PLEASE ****** I downloaded the file of csharp_net_shoppıng_cart_data_mining_component.zip. But I'm not using the program. Because i couldn't make a XML file. Do you send me a sample XML file? kurt_erh [at] hotmail.com

DO YOU HEAR ME?

JEYKARTHI:

You can download the APriori Algorithm code at http://www.kdkeys.net/forums/thread/2043.aspx

Hi,

I am a new researcher in data mining and I've downloaded your apriori implementation in C#.

I've faced the cryptographic error but I couldn't understand what do you mean by remarking the line that refers to the missing key in AssembliInfo.vb (AssemblyKeyFile)

Since this is published years ago, I wonder do you have a newer version?

Are you using VB.net not C#.net?

Are you using ADO.net technique, do you work on a connected or disconnected database?

 Is your code must work on XML file or it could work on a database with any format?

Have you made any updating on the Apriori algorithm which was first propoased by Agrawal?

Sorry for asking so many questions but I hope you could help me.

Thanks inadvance.

Hi Wedo:

1. As far as I understand, the development is done in C# and not VB.NET.
2. All you need to do to remove the error is to comment out the error message. In C#, this is done by putting a double forward slash in front of the code like this: // this line is commented
3. I believe I am using ADO.NET which works in disconnected mode fashion
4. The code works both on the database and on XML format
5. I have not updated Agrawal's algorithm, I just implemented a basic version of it.

The questions are okay. I will try as much as possible to answer them.

Regards

Dear Sir,

Thank you very much for your reply.

I have commented out the line [assembly: AssemblyKeyFile("")] in the file named AssemblyInfo.cs, but I still got the same error then I commented out the whole file but didn't work.

Could it be an error in the version of the .Net I use, I use(.Net2003) 

I appreciate your help in that .

I also want to know, have you used an OLEDB object to define the data, can I use SQL data?

Thanks inadvance

Dear Kingesly,

Now I have tried to execute the code, there was no errors but

The first form doesn't include any buttons just a data view

So I created the buttons and transfere the code

The data connection button works but when I click on OK button, the program doesn't work and I have to terminate it

Could you help me in this?!

I have another question

Is there any tutorial explain the functions and classes used?

Thanks in advance

Dear Wedo:

There is a Windows GUI FrontEnd that includes a functional button you can use to execute the program.

You don't have to create a GUI.

Also, there are no tutorials for the program. This is largely a demonstration program I created many years ago and as such it is for the most part un-supported.

Thanks

I believe I have answered this question.

There is a Windows GUI that comes with the application which you can use.

There is no tutorial for this application.

Thanks

Dear Sir,

Now I have no problem in executing the program but I don't understand what kind of database should I apply it on.

For the transactions method should the DB contains 2 tables, one for the items & the other for the transactions itself?

When you say DB you mean working on a certain table in the DB or on the whole system

If you could please give me example on the NorthWind DB explaining what do we mine, I mean for the min. support what attribute is it on? as I couldn't understand association rules generated in the output.

Thanks in advance

Dear Sir,

During my trials to execute the program, I have read the XML files but as far as I know the database should contain 2 tables one for the items and one for the transactions

but I found out that there are more tables so why do I have a table that generates the count of items isn't supposed to be generated during generating the candidates?!

Hi Kingsley,

Many thanks for your contribution, it does help the community a lot if more ppl like you could contribute ;)

I looked at your code and tested the sample program, I just like to ask in the examples .xml file.
Which do I change to add in my own terms or objects? I'm looking for a text clustering algorithm
which can tell me the similiary between words, wonder if this is the right one.

Cheers.

This is amazing code. keep up the good work.

Goodday Kingley,

 Thanks for the link for the code. I would like to find out if you have the latest version of this string maching algorithm in C/C++ codes but not in VB.

 

Do you have the C/C++ code types please. If you have the C codes, can you please give me aceess to download that type pleas.

 

Thanks.

Hello Mr. Kingsley.

can you tell me how can I exwcute the program.I  connected to the data but when Ipress the analyze button I the message  <System.IO.FileNotFoundException: Could not load file or assembly 'ShoppingCartSalesDataMining, Version=1.0.1117.36028, Culture=neutral, PublicKeyToken=a59e2f581e854ade' or one of its dependencies. The system cannot find the file specified.
File name: 'ShoppingCartSalesDataMining, Version=1.0.1117.36028, Culture=neutral, PublicKeyToken=a59e2f581e854ade'>

I commented  out the assembly line but it didnt work out. And also there is two Assembly.info.cs files which one should I comment out the line. I tried tocomment out the line in the two files.

thanks
