Ship-SIBISCaS: A First Step towards the Identification of Potential Maritime Law Infringements by means of LSA-Based Image

Table 1

A comparison of the execution times of a classical LSA system vs. the hLSA system using 5000 input documents, two weighting schemes, and k = 300 dimensions for three use cases.
