Hi all,
Just to let everyone know that I have posted a video presentation of the MinFHM algorithm:

In pattern mining, there is a lot of possible topics:
- new applications of algorithms
- designing faster algorithms for an existing pattern mining problem （you can choose a problem and find a way of improving the performance)
- designing a new problem for pattern mining (you need to think about some limitations of the current pattern mining problems and think about something new that you can

Welcome to the forum.
There are a lot of ways that pattern mining or itemset mining can be used to analyze text.
For example, itemset mining has been used in information retrieval to search for documents. In that case, we can extract itemsets representing frequent words common to a group of similar documents.
We can also use pattern mining to discover hidden features in text such as the w

Hi Nima,
I see.
I remember that a few years ago I saw a paper about some algorithms called FPGraph or something like that. Some person contacted with me by e-mail to ask me to implement this algorithm. But it was not published in a good journal if I remember well, and maybe even that it was an incorrect algorithm because the paper lacked details from what I remember.
After that I did not

Hello,
Yes, there are many algorithms to discover patterns in graph.
For example, there are several algorithms to discover frequent subgraphs in a graph or multiple graphs. Such algorithms are GSpan, FSG, etc. For an overview of frequent subgraph mining, here is an introduction to frequent subgraph mining. Besides that people will also discover other types of patterns such as cliques in grap

Dear Hung,
Just to let you know that I have updated SPMF a few minutes ago. I have included your bug fix for MinFHM. Besides that I have added 5 new algorithms!
Also, as promised, you are now in the list of contributors. ;-)
Thanks for your help!

Dear Yao,
Thanks for your interest in our paper. Yes, these algorithms are indeed very fast, as shown in the paper
If it was me, I would put the code in SPMF, but although I am a co-author, I am not the main author of this paper. Please contact Tin Truong Chi or Bac Le to request for the source code.
Best regards,
Philippe

Hi,
Thanks for using SPMF. There is some datasets on the SPMF website but you are right that they do not provide the name of the webpages.
The original FIFA dataset contained this information: http://ita.ee.lbl.gov/html/contrib/WorldCup.html
But it is not in SPMF format. So you could convert it to SPMF format again and keep the page label. That would be a solution to obtain click streams

Hi,
Yes, I think you are right. There seems to be a bug in the implementation. Thanks for reporting it. I should release a new version of SPMF in about 1 week and half because I will have a week of holiday. I will then fix the bug, and also add several new algorithms related to high utility itemset mining that some people have sent to me recently.
By the way, I will also add your name to th

Thanks Dang,
I see. An XML format. I don't like too much XML-based format personally. It wastes a lot of space with all these tags. Already the text-based format of SPMF takes a lot of space because it is a text file. This format would maybe make the output files 10 times or more larger. Just my opinion. But I understand that it can be useful for interoperability with other software.

Hi,
Thanks for using SPMF. I do not know what is the PMML format. But if you are comfortable with Java, you could modify the code for writing the rules to the file. This should not be hard. In SPMF, each algorithm is in a separated package. So you could first find the code of the algorithm that you want to modify and then change the code.
But what is PMML? Can you give me a link to a websit

Hi,
There is a lot of possible topics. You can choose to work on something more fundamental like algorithm design or something more applied such as how to best solve a given applied problem.
A good way of choosing a research problem is to look at some recent papers and find something that you are interested in. Personally, I am quite interested in pattern mining problems and algorithm desi

You may export the data from the database to a text file in the proper format and they apply Apriori to the text file to obtain the result.
But it depends on your implementation of Apriori. If you are using the implementation from the SPMF software, then you should read the documentation to see which format is required as input.
