Automatic generation of test cases to improve code coverage in Java

Galindo Jiménez, Carlos Santiago (Universitat Politècnica de València, 2019-01-10)

[EN] Given a test case and a program, there exist multiple tools that observe and analyze the execution of the program, determine which sentences have been executed and follow the value of the different variables. This ...
Boosting training process using active learning in dialogue act labelling

Ghigi, Fabrizio (Universitat Politècnica de València, 2012-05-03)
Construcción de un grafo de palabras a partir de los índices probabilísticos

Arroyo Linuesa, Luis (Universitat Politècnica de València, 2024-01-02)
