IFS mir group Webservices
On this web page we provide web services for
After an introduction to what the web services exactly can do, a demo webservice client is provided and also the specifications which allow the use of this web service in your own applications.
With the use of these features it is possible to tell about the content of a piece of music without the need of annotated labels such as artist, song title or genre. With this information, in turn, similarity between pieces of music can be computed and applications such as music classification, automatic music organization, playlist recommendation and many more are made possible.
Our group also conducts research on data mining methods and in particular the Self-Organizing Map (SOM). The SOM is a prominent technique for exploratory data analysis and visualization of complex high-dimensional data sets [more about SOMs].
We have successfully introduced a SOM application, that organizes entire music collections on a Self-Organizing Music Map providing convenient overview and immediate interaction with your music collection, organized by music similarity - including creation of situation/style-based playlists. [more about PlaySOM and music maps]
If you want to play with our feature extractor or the SOM-trainer we provide a simple client implemented in Java. After you received your voucher you can easily launch the client using Java Web Start. This client requires Java1.6.
Because the client needs access to your computer's storage and network connection the jar-file is signed. Java Web Start will prompt a warning that "The application's digital signature cannot be verified." This is normal, so just click "Run" to finally start the Demo-Client. If you want to check the certificate, you can compare the MD5 Fingerprint: 83:DE:BC:30:D6:7B:7B:3F:22:93:E5:A6:53:D8:94:1E
Using this client you can easily analyse your mp3-files and afterwards create a SOM containing your music. Please keep in mind that all files you are going to analyze will be sent to our webservice over the Internet, so your traffic-counter might increase quite fast...
We have created webservices that allow online
audio feature extraction
Also for using the Webservice with your own client you
need to get a voucher which has to be sent along with every requests.
For more detailed information on the Webservice-interface please look at the javadoc-API.
