broken links to SemOpenAlex authors #5

@davidlamprecht 

curl -L -Haccept:text/turtle https://linkedpaperswithcode.com/paper/on-the-use-of-arxiv-as-a-dataset
  owl:sameAs                   ns4:W2943043881
  dcterms:creator              ns7:A2033371752 , ns7:A2157679762 , ns7:A2143774550 , ns7:A2641167929

But these author links are broken (I looked at the first two).

cc @linnaung, @phaasenase: Looking in SemOpenAlex we find the true author IDs:

curl -L -Haccept:text/turtle https://semopenalex.org/work/W2943043881
  dct:creator <https://semopenalex.org/author/A5035136886>, <https://semopenalex.org/author/A5036325834>,
    <https://semopenalex.org/author/A5035741296>, <https://semopenalex.org/author/A5007389688>;

This is because OpenAlex released a completely redesigned and improved author disambiguation in July 2023. As a result of this change, the old OpenAlex author IDs were deprecated and new author IDs were assigned to all authors (see: https://docs.openalex.org/api-entities/authors/author-disambiguation).

These outdated links to SemOpenAlex authors are only included in the first LPWC version v1. The new LPWC version v2 contains the up-to-date links to SemOpenAlex authors.

We have published the new LPWC version v2, which is based on the Papers with code dump from 19.12.2023, on zenodo today (see: https://zenodo.org/records/10479729). The new version is also already loaded into the public SPARQL endpoint.

The new LPWC version v2 is now accessible via the SPARQL endpoint and curl. E.g. See the correct links to SemOpenAlex authors for your example:

curl -L -Haccept:text/turtle https://linkedpaperswithcode.com/paper/on-the-use-of-arxiv-as-a-dataset
  owl:sameAs                   ns4:W2943043881 ;
  dcterms:creator              ns7:A5035741296 , ns7:A5007389688 , ns7:A5035136886 , ns7:A5036325834 ;
