Systems, methods, and software to manage tags in association with vertices of a graph. In one implementation, a graph management system identifies a request to tag vertices in the graph, wherein the request indicates one or more attributes to qualify for the tag as part of a conditional expression. The graph management system further identifies vertices in the graph with the one or more attributes. Once identified, the graph management system assigns the tag to the vertices wherein the tag comprises an attribute assigned to the identified vertices.

Managing vertex level access in a graph via user defined tag rules

Systems and methods for enhanced detection of fraudulent electronic transactions are disclosed. In one embodiment, a system uses the ongoing stream of transactions to construct and maintain a dynamically evolving merchant relationship graph. When a proposed transaction is submitted to the system, the system computes a predicted likelihood that the given account would make a transaction with these characteristics with the given merchant. The graph is used to compute transitive relatedness between merchants which may be indirectly associated with one another, as well as to compute aggregate relatedness, when there are multiple avenues of relationship between two merchants.
