FlexER: Flexible Entity Resolution for Multiple Intents

1 code implementation23 Aug 2022 Bar Genossar, Roee Shraga, Avigdor Gal

In what follows, we introduce the problem of multiple intents entity resolution (MIER), an extension to the universal (single intent) entity resolution task.

SKTR: Trace Recovery from Stochastically Known Logs

no code implementations25 Jun 2022 Eli Bogdanov, Izack Cohen, Avigdor Gal

Developments in machine learning together with the increasing usage of sensor data challenge the reliance on deterministic logs, requiring new process mining solutions for uncertain, and in particular stochastically known, logs.
