Conceptual architecture. Overview of the conceptual architecture of the proposed ranking- and retrieval system. A version has been implemented in BioModels Database. The architecture shows the process of transforming a user given query by creating sub-queries, which are then assembled by enrichment of structural information and semantic indexing (see also Figure 3). The re-assembled query is then sent to the retrieval and ranking module, which makes use of the Extended Boolean Model to retrieve a list of matching models, and the Vector Space Model to rank the list of retrieved models. To determine the ranking, different weight information is used. Those are, however, not shown in the given Figure.
