▫Knowledge extracting from data and information▫Enriching data and information with knowledgeShows that this new analysis method is successful with the help of visualization and formalized knowledge models to find relevant information quicker

Formal concept analysis218 cases of domestic violence ▫ 202 cases domestic violence and with

suspect (‘Verdachte’)▫ 12 cases domestic violence with description

of suspect (‘Signalementen’)9 cases with domestic violence, suspect and description of suspectLeaves: 3 cases domestic violence with description of a suspect but no formally labeled suspect is mentioned?!▫ All are mistakenly labeled as domestic

violenceFrom this analysis a knowledge rule can be obtained:▫ Violence cases with a description of the

suspect but not mentioning a formally labeled suspect can be classified with accuracy of almost 100% as non-domestic violence.
