One of the fundamental elements for achieving this objective is the relationship between process modeling languages, process event logging (logs) and Process Mining algorithms. In this work, comparisons were made between three languages (BPMN, Petri Nets and YAWL) which are usually used to model business processes with respect to their capabilities of use in Process Mining, especially in Process Discovery. The models created were based on typical Workflow patterns and five scenarios were simulated for each language using three Process Discovery algorithms (Alpha, Heuristic Miner and ILP Miner). The results indicate that the choice of the language used in the modeling and in recording of the business processes influences the quality of the results obtained by the Process Discovery algorithms. This work also presents suggestions for the development of process modeling languages and process mining algorithms. / O armazenamento das informações em grandes repositórios de dados (Big Data) geram oportunidades para que as Organizações utilizem técnicas de Mineração de Processos (Process Mining) para extrair conhecimento sobre o desempenho e o fluxo real de seus processos de negócio. Um dos elementos fundamentais para que este objetivo seja alcançado está na relação entre as linguagens de modelagem de processos, o registro dos eventos de processo (logs) e os algoritmos de Mineração de Processos. Neste trabalho, foram realizadas comparações entre três linguagens (BPMN, Redes de Petri e YAWL) normalmente utilizadas para modelar processos de negócio com respeito a suas capacidades de utilização na Mineração de Processos, em especial, na Descoberta de Processos. Os modelos criados foram baseados em padrões típicos de Workflow e cinco cenários foram simulados para cada linguagem utilizando três algoritmos de Descoberta de Processos (Alpha, Heuristic Miner e ILP Miner). Os resultados indicam que a escolha da linguagem utilizada na modelagem e no registro dos processos de negócio influencia na qualidade dos resultados obtidos pelos algoritmos de Descoberta de Processos. O trabalho também apresenta sugestões para o desenvolvimento das linguagens de modelagem de processos e dos algoritmos de Mineração de Processos.
