I want to work on XML documents using XQuery.so,which data mining tool will take xml documents as input and perform xquery on it and fetch data from xml documents.
And then i new approach that i program is imported to that tool so that can generate association rule from that.

Can you please suggest data mining tool.Ex. WEKA that support for java class file to be imported for developersBut it supports for XRFF,CSV,ARFF file formats.I don't want to manually convert xml documents into csv files,i want to perform xquery so that preprocessing and postprocessing can be avoided.
What are other tools can i use for c#.net programming that can support xml files also.

A lot of confusion about implementation which i am not able to figuring out.

NEed help.
Share your knowledge,may be it can help.
Thanx.

I don't know any data mining tools that support XML document with XQuery since it seems like a pretty specific need but there are some general purpose library that exists for handling XML documents. So a possibility may be to use two librairies. One for handling XML documents and one library for data mining. And then you write the code between them.

For the boolean matrix, so basically, it is the typical input of Apriori, what is called a transaction database. By "boolean matrix generation" i guess that you mean converting your XML documents.

So each file is a transaction (line) in your transaction database (boolean matrix).

In my opinion, it would be very simple to write a Java or C++ program that read each file and checks if the keywords appears in it and create your matrix.

Re: Apriori algorithm in C# or Java

XML is not a file format. It is a meta-language. It is used to define file formats that have tags. There exists thousands of file formats that are defined using XML such as MathML, XHTML, etc.

Thus, you will not find a universal tool that could convert all XML formats to Arff format. Thus, you should probably restrict yourself to a specific XML format such as XHTML for webpages.

Besides, a second reason why converting any XML files to ARFF would be difficult is that XML are represented as a tree, while a ARFF file represents a flat table as in a relational database. But if you want to convert a specific XML format to ARFF such as XHTML, then you could program a tailored way of converting the format to ARFF.

You need to go to the download page and download the source code of the SPMF library.

It contains the code of CHARM.

To know how to compile the source code, you can read the installation instructions on the download page. It explains clearly how to compile and run the algorithms. After you read it, you will be able to run CHARM.

If you just need the code of CHARM and not all the algorithms, you may read the developper guide on the download page that explain how the source code is organized, and it should be pretty easy to just take out the code for CHARM.

HI,

MainTestAprioriClose_saveToFIle is the file for running the example. It contains the main() method.

AlgoAprioriClose is the algorithm itself. But you probably also need a few more files.

You can look on top of the AlgorAprioriClose file and see the import statements to see what classes it needs.

Re: need to generate rules from frequent closed item set
Date: February 25, 2015 03:36PM

In SPMF, you can mine the "closed association rules" using the "closed itemsets". However, this feature is currently only implement using some closed itemset mining algorithms such as CHARM.

You can see Example #40 ( http://www.philippe-fournier-viger.com/spmf/index.php?link=documentation.php#example20 ) to get more information about closed association rules.

This example correspond to the file "MainTestClosedAssociationRules_saveToMemory" in the source code.

Note that it would in theory be possible to use AprioriClose instead of Charm but it would require to perform some modifications to the code. Because AprioriClose is not an efficient algorithm compared to Charm, it is in my opinion better to use Charm instead of AprioriClose, unless you have some very specific reasons for using Close.

Hi,

I need your help urgently.
I have a summer course of DataMining, and I have to do a project for it.
Unfortunately I don't know so much in programing, Therefore I need your help please:

Project: find a most frequent path

- I have a dataset with 100,000 records, and each records represent one day trajectory of a passenger
- Records could contain 2 till 8 location (items), It means, a passenger can move between 2 locations till 8 locations
- Total number of locations are 65
- Order between locations is important. L1,L2 is different than L2,L1

Now, I have to find the most frequent path from this dataset.
The algorithm that I probably should use is "Frequent Sequence" which is like Apriori but we have to consider each association 2 times (L1,L2) and (L2,L1) separately.
Also, I have my own algorithm to realize it as well, I have to run both and compare them.

May I know if somebody could help me with this project please.
(I prefer to use MySQL as my Data base and Java or C as programming language and Also if I could run it on my MAC)

* Also, I can pay to anyone who can do it correctly for me.

Are there some advantages of one language C and Java over the other? Which one is optimal? Which one is more "future proof"? Would it be optimal to know both? If so, which order? I am a little confused on the subject. Just got across this course http://www.wiziq.com/course/1779-core-and-advance-java-concepts, will it be helpful also. A little enlightenment could help. Thanks

Hi,

It depends what you want to do.

C++ is compiled directly into binary code. Therefore, the program that you write in C++ are directly run by your computer.

Java is not compiled directly into binary code. It uses what they call "byte code". Basically, any Java program is interpreted at runtime in what they call a "virtual machine". So normally, Java is slower than C++.

But Java has some advantages. You can write your program and it can run on Windows, Linux, MacOS, etc.

If you write your program in C++, you can also recompile it for different platform like Linux, Window, etc. BUt it is not as easy to do as Java.

Java is also used for software on Android phones. So if you want to do programming for Android, you better know Java.

But if you want to do programming for Apple iphones, it uses Objective C, a variant of C++.

If you want to write an operating systems, drivers or video games for windows, you would need to use c++.

Besides, Java is easier to learn than C++.

In my opinion, a good programmer should know both of them, or otherwise C# and C++. But if you know only one of them, you could still do a lot of stuff.

Hopes this helps,

Philippe

In terms of features, both Java and C# are quite easy to use and provide similar features. But in my opinion, there are more source code available in Java for pattern mining (e.g. the SPMF library). So if you plan to reuse the source code of someone else, maybe Java may be a better choice.

Thanks Phillipe sir,

I am going to mine XML documents so,if i choose JAVA ,i can use WEKA i.e. wellknown mining tool.But it supports for CSV,ARFF like files.Not pure XML files.It supports for XRFF files that is Extensible ARFF file.

I do not want to manually convert xml to XRFF.Is it any possible way that XQuery i can perform and result i get in such a format that i can apply to Weka directly.So that no preprocessing on XML documents to convert into relational database and then injecting db queries(sql like queries).

I am bound to this XQuery specific need.Help me if you can.

I cannot help you too much since it is a very specific need and I don't work with XML and XQuery for data mining. If I were you, I would write some simple code to convert the documents to the required format. I know that you don't want to do that. But it is still maybe the most simple solution. Weka is a good general purpose data mining library. But if you want to do pattern mining, it is not the best library. Basically, it only offers two or three algorithms (Apriori, FPGrowth mainly), and the Weka implementations are very slow (for example, a performance comparison with SPMF where Weka is about 100 times slower for FPGrowth: http://www.philippe-fournier-viger.com/spmf/performance/chess_fpgrowth_spmf_vs_weka.png ). By the way, SPMF can also be used with ARFF.

Re: error message

It seems that the format of your input file is incorrect.

The input for FPGrowth is a text file like this:

1 3 4
2 3 5
1 2 3 5
2 5
1 2 3 5

Each line represents a transaction.
Each line is a list of items where items are integers separated by a space.

You can find some examples of input file from the download page by downloading test_files.zip:

http://www.philippe-fournier-viger.com/spmf/test_files.zip

An example of file for FPGrowth is contextPasquier99.txt

This file is the file used in the example for FPGrowth in the documentation of SPMF.

Re: error message
Date: May 31, 2013 02:25PM

Hi Harpreet,

Each integer represents an attribute value. You can give any meaning to the integers. It depends on how you use the algorithm.

For example, an integer "1" could mean the value "teenager" an attribute "age", an integer "2" could mean the value "adult", etc.

By the way, tonight I planned to release a new version of SPMF that will be able to read ARFF files, so you will be able to use attribute names. I don't know if you are familiar with this kind of files or not. It is a text file that represents a table in a relational database. You will be able to use this kind of file with all the itemset and association rule mining algorithms in SPMF.

Best,

Philippe

To see how to use SPMF, you should go to the download page:

and then follows the installation instructions. It explains how to run the examples using the provided example input files.

If you want to use your own dataset, then they need to be in the correct input format. The input format for each algorithm is explained in the documentation page.

Moreover, besides the default input format, some examples in the documentation explains how to use the ARFF format and to convert some other format if you need to.

What do you mean by "help me"?

Do you mean that you would like that I implement the code for you?

If this is what you mean, then no, I don't have time to do that.

But if i understand well, the problem is that you want to use a different input. Then, a solution is to take my source code from the website and then to change the code for reading the input file to read your format instead. Or another way is to write some program to convert your input format to the input format used by my implementation.

Re: Apriori algorithm in C# or Java

1) The definition of data mining is very broad. It is to discover new knowledge from some data. It can be applied in a wide range of applications https://en.wikipedia.org/wiki/Data_mining

2) Apriori is an algorithm to discover frequent patterns groups of items that appears often in a set of transactions). If you have a problem that can be represented as a set of transactions where you need to find patterns that appear often, then Apriori can be applied. Some example is to discover items that are frequently bought by customers in a store.

3) Briefly, Java is a general purpose object-oriented programming language that can be used for very large projects. Matlab is specially designed for numeric computing. For implementing Apriori, I recommend using Java instead of MATLAB because you doN't need the high level mathematical operations of MATLAB, MATLAB is generally slower than Java, and Java is free

4) best way to develop Apriori? First, read and understand the algorithm. Then, implement it so that it output the correct result. Third, try to optimize it by looking at optimizations.

Hello,

1) You need to understand the Apriori algorithm. For this, you can read the description of the algorithm in some books or the article about Apriori.

2) You need to know at least one programming language (Java, C#...).

3) Then, you should use the programming language to implement the algorithm.

That is all I can say. Besides, you may look at some implementations of Apriori available on the Web to see how they have done.

Re: Re:Rare association rule mining algorithm

If you have a horizontal database like this:

transaction 1: a b c d
transaction 2: b c d
transaction 3: a e

The vertical database will be:

a: transaction1, transaction3
b: transaction1, transaction2
c: transaction1, transaction2
d: transaction1, transaction2
e: transaction3

That is how we convert from horizontal to vertical database. Now, this can be done in Java or any programming language. You just need to find out how to read Access file and convert it. Or if you juste have 6 transactions, then why you don't do it directly by hand?

Problem: This is our second programming assignment. This assignment has three parts:
 Part 1: I ask you to write a program to implement the classical Apriori algorithm to find the most frequent item sets and then generate association rules from these item set.
The two parameters are given as follows:
minsup = 30%
minconf = 90%
The most frequent item set shall be output and saved a text file called “mfis.txt,” and the association rules shall also be output and saved in another text file called “ar.txt.”
Note: You may use any reasonable heuristic to in your implementation to improve the running time performance of the Apriori Algorithm.
 Part II: I ask you to sort the associate rules obtained from Part 1 according to confidence values, and then output the top 10 association rules with highest confidence values. These top ten association rules shall be output and saved in the third text file called “topar.txt.”
 Part III: In word file, I ask you to evaluate the top ten association rules and briefly explain whether each of these rules is meaningful or not. Save your word file as “explan.doc” or “explan.docx.”
 Data set: The data set is the 1984 Congressional Voting Record Database archived at
UCI Machine Learning Repository:

You may have a look at the source code in the SPMF library and debug it to see how it works.

Hello,
I'm doing my master thesis in association rules and i need code in R or Java in order to apply multiple support apriori.
The ideia is to define more than one support to find association rules in a data transaction with frequent and rare items.
Hope someone can help me smiling smiley

Thank you

You can use the MSApriori implementation or CFPGrowth implementation offered in the SPMF library. With these algorithms you can mine frequent itemsets with multiple minimum support threshold.

Besides, in SPMF, you can generate association rules with CFPGrowth.

I would recommend to check these algorithms.

Best,
