Poverty and social exclusion are a reality in every society. They are complex problems that require updated information and access to scattered data sources to make a proper assessment of a person’s situation. To help social workers with these tasks, we developed the Lindaview tool at the suggestion of the Social Services Department of the Barcelona City Council. Assessment of individuals seeking social assistance is not standardized, as it depends entirely on the social worker’s perception and experience. We design a tool that provides an informed starting point for the assessment of an individual’s self-sufficiency. Furthermore, we included a section of general statistics, allowing policymakers to access comprehensive, updated, and timely information, empowering them to make data-based decisions when allocating available resources. Lindaview is an OBDA-based tool. OBDA (Ontology- Based Data Access) is a paradigm that allows accessing data from its original source without data migration or updates on the original data architecture. Moreover, with this paradigm, we can infer implicit information via ontology reasoning.
