    <p>I'm searching for an algorithm respectively a method for learning user actions (inputs) in a certain program, and, based on a built information base of done user actions, to offer suggestions for future actions to the user. The information base should be built from the actions of multiple users using the same software. The user actions are dependent on the order in which they occur. This means, that a suggestion should be made based on already done user actions in a session. A session is an abstract time period, in which the user works with the software.</p> <p>In my initial approach, I thought of moddeling the user actions in a directed graph, where each node represents a unique user action instance. A user action, done for the very first time, generates a new node. The nodes have a counter representing how often a user did this user action. A transition from one node to another exists, when a user action is done after another one (modelling the sequence of user actions). For every transition, the probability is computed based on the counters of the subsequent nodes (i.e. nodes, to which there is a transition). There is a root node as starting point, which directs to all initial nodes (user actions done first in a session). This could be a (hidden) Markov model, but I am not sure. It is definitely not a Bayesian network, because it can be a cyclic graph (desireable).</p> <p>Are there already methods, algorithms, libraries etc. for this problem? If not, how is my approach? Any alternatives, better ideas?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
