The Balance between Nuance and Clarity: Decluttering Tabular Sequential Graphs to Counter Money Laundering

Louise Fallon, Pedro Bizarro, Rita Costa, Salom\'e Esteves

Grouping transactions by amount and timing reduces clutter in sequential graphs used for money laundering analysis, with a user study showing that simpler reductions are not always the most useful.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

A user study with experts revealed that the most effective method in node reduction was not necessarily the most interesting for analysis and that there is a trade-off between manual work and time for interpretation in more granular graphs.

C2weakest assumption

That the three proposed grouping methods preserve enough transaction nuance to support accurate money laundering detection while the expert opinions in the user study reflect real operational needs and generalize beyond the study participants.

C3one line summary

Tabular sequential graphs with amount-based, time-based, and combined grouping reduce nodes and edges for AML analysis, but expert users found a trade-off where stronger node reduction was not always preferred for insight.
