ordered sequence mining

Question

Hello

I would like to work on my data, the data are ordered sequences.

I would like to classify and detect anomalies.

A technique like association rules is not the best option as I need a technique which takes into account the order of the sequences in order to detect the anomalies.
I need a technique that uses wild-cards/gaps in order to detect the probability of a sequence.

I saw some sequence mining techniques like sparse markov trannsducers but I can't find any software or open source to deal with the sequence mining problem.

If anyone knows a softawre to treat this problem I will be more than happy.

Thanks a lot

SQL Server includes Sequence Clustering algorithm.  You can read and learn about it by running this tutorial http://msdn.microsoft.com/en-us/library/ms167594(v=sql.90)
