Week 1 – Kicking off & constructing the knowledge base

This week we spent a lot of time discussing our work plan and expected outcomes, as well as how we collaborate with each other since project 1 and 2 are closely related and are both extension to the semantic annotator in Tetherless World.

For project 2 mainly we need to achieve two features: enabling Ontology Search based on keywords and enabling ontology recommendation based on usage history. For Ontology Search we are implementing an entity linking & similarity ranking tool in our lab. So my first job is to construct the knowledge base on which our tool will be testing. We have done a collection of earth science ontologies and I pre-processed these datasets together with the annotator pre-loaded ontologies for our initial test.

I also read the Morpho paper, particularly the part about automated metadata extraction: “Higgins, D., Berkley, C., Jones, M., 2002. Managing heterogeneous ecological data using Morpho. Proceedings of the Fourteenth International Conference on Scientific and Statistical Database Management, pp. 69–76.”, which gives me some insights regarding how we gonna do the recommendation part.

We are expecting good testing results next week and I will keep merging useful ontologies into our knowledge base if necessary.
