merge MLSea and LinkedPapersWithCode

dtai-kg/MLSea-KGC#2 would be a major undertaking but with immense value :-)

Hi @VladimirAlexiev ,
thank you for pointing out this opportunity to significant increase the interlinking within the scholarly LOD Cloud.

As a first step I linked publication, repository and dataset entities from Linked Papers With Code to the corresponding MLSea entities using owl:sameAs links.

In total there are now the following owl:sameAs triples in the linkedpaperswithcode database:

• 442,742 owl:sameAs links between LPWC papers and MLSea Scientific Works.
• 152,554 owl:sameAs links between LPWC repositories ans MLSea Software.
• 8,887 owl:sameAs links between LPWC datasets and MLSea datasets.

All sameAs links are stored in the named graph https://linkedpaperswithcode.com/mlsealinks in the linkedpaperswithcode GraphDB repository.

Example owl:sameAs RDF triples:

• paper link: <https://linkedpaperswithcode.com/paper/sticc-a-multivariate-spatial-clustering> <http://www.w3.org/2002/07/owl#sameAs> <http://w3id.org/mlsea/pwc/scientificWork/STICC%3A%20A%20multivariate%20spatial%20clustering%20method%20for%20repeated%20geographic%20pattern%20discovery%20with%20consideration%20of%20spatial%20contiguity> .
• repository link: <https://linkedpaperswithcode.com/repository/github.com/ibm/multimodal-3d-image-segmentation> <http://www.w3.org/2002/07/owl#sameAs> <http://w3id.org/mlsea/pwc/software/3D%20Segmentation%20with%20Exponential%20Logarithmic%20Loss%20for%20Highly%20Unbalanced%20Object%20Sizes> .
• dataset link: <https://linkedpaperswithcode.com/dataset/wiki-squirrel> <http://www.w3.org/2002/07/owl#sameAs> <http://w3id.org/mlsea/pwc/dataset/Wiki%20Squirrel> .

Example federated SPARQL Query for a paper executed over the LPWC SPARQL endpoint:

PREFIX owl: <http://www.w3.org/2002/07/owl#>
PREFIX Service: <http://www.metaphacts.com/ontologies/platform/service/>
SELECT *
WHERE {
  GRAPH <https://linkedpaperswithcode.com/mlsealinks> {
    <https://linkedpaperswithcode.com/paper/sticc-a-multivariate-spatial-clustering> owl:sameAs ?mlsea_paper .
  }
  SERVICE <http://w3id.org/mlsea-kg>  {
    ?mlsea_paper ?predicate ?object .
  }
}
