Jena/SPARQL outperformed Prolog for spectrum similarity search
UPDATE 29/3: See new results hereI was a bit worried over the performance of the RDF facilities in Bioclipse, as a SPARQL query for doing NMR Spectrum similarity search, including a numerical...

Egon pointed to an interesting blog post about a feature that is available as a an extension to Jena, the semantic web framework available in Bioclipse. It allows to very easily query multiple SPARQL...
View ArticleCorrection of flawed results: Close competition between Jena and Prolog
UPDATE 29/3: See new results hereI reported in a previous blog post (with a bit of surprise) that Jena clearly outperformed SWI-Prolog for a NMR Spectrum similarity search run inside Bioclipse. I have...
View ArticleOn larger datasets and more peaks in the query, Prolog is the fastest
In a previous performance test I compared a NMR Spectrum similarity search programmed in Prolog and run in SWI-Prolog integrated in Bioclipse, against a SPARQL Query doing the same task, run in Jena,...

I just had my 3rd, and last project update presentation (before the final presenation on April 28th), presenting results from comparing the performance of the integrated SWI-Prolog against Jena and...
View ArticleProlog query much faster when mimicking SPARQL
I reported earlier that Jena/SPARQL outperformed Prolog for a lookup query with some numerical value comparison. It later on turned out that the results were flawed and finally that Prolog indeed was...
