RESUMO

Biodiversity information systems need and manage heterogeneous information provided by different research groups. Heterogeneity occur with respect to the species studied, the structure of the information gathered, the region of study, the work methodologies, or the vocabularies and objectives of the researchers, among other factors. This heterogeneity of data, users and procedures hampers information sharing and reuse. This work contributes to reduce this obstacle, improving the query processing mechanisms in biodiversity systems. Its main interpretation is a query expansion mechanism that pre-processes a user (scientist) query aggregating additional information from ontologies, thereby approximating query results to what is intended by the user. This mechanism is based on Web services and was implemented and tested using real case studies
