About my master project

with one comment

To make sure that this blog won’t be about funny process models alone it might be a good idea to introduce and explain my master’s project subject: Mapping Data Sources to XES in a Generic Way. Let’s dissect this rather vague sentence to explain what it is all about:

Mapping: in this context it means to let the user define a way to map one data source to another.

Data Sources: most people might think of databases first but text files, XML files and even web services can be considered as data sources. Although it must be seen how many data sources we are able to support, we intend to at least support the common database formats and the CSV (comma separated values) plain text format.

XES: the one requiring the most explanation. Although pronounced (as ‘excess’) similar to one of the well known database formats from a well known software vendor, it means something completely different. In this case we refer to the ‘Extensible Event Stream’ format. This format is an extend-able event log format for, well, storing event logs. For people familiar with the MXML format: XES is the new and improved MXML! For people unfamiliar with MXML: visit processmining.org (more specifically, read an informal introduction to MXML (.PPT, 0,9 MB) or read the more formal MXML introduction paper (PDF, 130 KB)). The XES meta-model is implemented in the OpenXES Java library, more information about XES can also be found there.

a Generic Way: of course, we want our application to be applicable in many situations and therefore it must be generic.

So, in brief, the goal of my project is to develop an application that allows a user to define a mapping from a (set of) data source(s) to the XES event log format and to execute this mapping. Resulting in an event log format that can be used for process mining with (the new version of) ProM.

If you have done one or several process mining project you must know that preparing the data is one of the most time consuming (and, in my opinion, most annoying) part of the process mining project. This master project aims at providing an application that will allow you, the process miner, maybe together with the domain expert, to define a mapping from the data source(s) to the XES event log format without the need to write (Java) code.

Any questions, comments, feature requests etc. etc. are more than welcome!!!

See you at the next post! (Which will either be a ‘funny process model’ or a post showing some GUI designs for the application)

Hello world!

with one comment

Welcome to my personal blog on WordPress.com. This is my first post.

And since this is my first post, I’ll tell a little bit about me and why I started this blog.

So, I’m Joos Buijs from the Netherlands. At the moment I’m a graduate student ‘Business Information Systems‘ at Eindhoven University of Technology. I’m working at my master thesis/project which is related to process mining, a ‘hot research topic’ at the group I’m working at. But more about my master project in a later blog post.

The goal of this blog is mainly to create a ‘personal brand’, or in other words, to promote myself to future employers, colleagues and the rest of the world. Secondary, but not less important, I want to get in contact with new people and share idea’s and opinions and help each other. For instance, I believe that my master project might help people active in process mining and they can provide me with tips to improve my application.

If you want to get to know me better you can read my ‘online resume’ also known as my LinkedIn profile (which also includes a picture or myself, to make it more personal). And of course, you can always contact me by adding a comment, send me a message or try to meet me in real life 🙂

That’s it for now. I cannot promise a regular update schedule, in most cases its contradictory to my work schedule. Right now for instance I’m taking a break from reading a book (on plug-in development in Eclipse) but when I’m ‘really working’ I have less time to post something interesting (although then I’m likely to have something interesting to post…). Anywho, hope to see you soon!!!

Take care,

Joos
