| Project Name | iBioSearch (Integrated Biological Database Search) |
| Description | The integrated biological databases search (iBioSearch) system is aimed at providing a unifying interface and advanced capability for searching various online biological databases. The iBioSearch system is an online search system which dynamically builds a biological database search ontology as the user interface. The ontology acting as a global schema connects to more than 1000 online biological databases. User's queries against the ontology are translated into queries against underlying online query interfaces. Query results returned from the underlying databases are consolidated, reconciled, and ranked by data cleansing and relevance computing algorithms. Salient features of iBioSearch system includes dynamically updating biological databases repository and maintaining semantic mappings when base databases evolve. |

| Project Name | DDSMS (Drexel Data Semanitcs Management System) |
| Description | The Drexel data semantics management system (DDSMS) is aimed at managing semantic mappings from database schemas to conceptual models describing subject matters. Database practices suggest that data semantics amounts to establishing and maintaining semantic mappings from data to the intended subject matter. For database-resident data, it is managing the semantic mapping from the schema of a database to a conceptual model (CM) for the intended subject matter. The research on the data semantics management system involves discovering semantic mappings from legacy database schemas to existing conceptual models, searching the best fitted conceptual model(s) for capturing the semantics of a given database schema, maintaining semantic mappings when schemas and conceptual models evolve, and composing semantic mappings for data integration tasks. |
