It will run to the end of May 2025. </div> <h1 id="h1">Frequently asked questions</h1> <dl> <dt>How can I add information to Scholia?</dt> <dd> Scholia's information comes from <a href="https://www.wikidata.org/wiki/">Wikidata</a> and the English Wikipedia, so you should add data there. Use the <a href="https://www.wikidata.org/wiki/Special:Search">search page in Wikidata</a> to examine if the data item you want to add is already in Wikidata. If not, add a new data item with the <a href="https://www.wikidata.org/wiki/Special:NewItem">new item page</a> on the Wikidata site. <br/><br/> There are a number of tools to ease editing Wikidata, <!-- sourcemd is currently disabled. If you want to include a scientific document in Wikidata and it has a DOI, PMID or PMCID identifier then you can use Magnus Manske's <a href="https://sourcemd.toolforge.org/">sourcemd tool</a> (you need a Wikidata account and authorize Manske's tool to edit in Wikidata). If you want to update some information about an author and the author has an ORCID profile with public works, Magnus Manske's sourcemd tool also efficiently adds papers and authorships to Wikidata. There are a number of other tools, --> e.g. the <a href="https://author-disambiguator.toolforge.org/">Author Disambiguator</a> (by Arthur Smith, based on an initial version by Magnus Manske) that can help identify specific authors based on author name strings. </dd> <dt>Why is Scholia so biased and incomplete?</dt> <dd>Scholia's data comes mostly from Wikidata, and that data is not complete with respect to scientific articles, their authors, their citations or their annotations. Any scientometrics interpretation needs to keep in mind that the statistics might be severely biased. <br/><br/> The data entered in Wikidata are mostly incorporated from other databases, such as Pubmed Central and CrossRef. Works without DOI are less likely to be added to Wikidata because it is more difficult to automate the data entry. Most citations are also incorporated from other databases. Articles from publishers that do not release their citations (which can be avoided by participating in the initiative <a href="https://i4oc.org/">I4OC</a>) are less likely to have their citations entered in Wikidata. Researchers without an <a href="https://orcid.org/">ORCID</a> and their works are not publicly available with DOI on the ORCID website are probably also less likely to be linked with their works on Wikidata. There are quite likely other serious biases in Wikidata. Scholia can help highlight some of the biases and facilitate user actions to help address them. </dd> <dt>How do I report a problem</dt> <dd> Technical problems and similar are curated at <a href="https://github.com/WDscholia/scholia/issues">Scholia's GitHub issue list</a>. Use the search field to see if your problem is already listed or press "New issue" to make a new issue (you need to have an account on GitHub). <br/><br/> Content-related problems, e.g., wrong data, may be addressed by editing the underlying data in <a href="https://www.wikidata.org/wiki/">Wikidata</a> or leaving a message on the <a href="https://www.wikidata.org/wiki/Wikidata:Project_chat">Wikidata project chat</a>. </dd> <dt>Where can I read more about Scholia</dt> <dd> The <a href="https://www.wikidata.org/wiki/Wikidata:Scholia">Wikidata:Scholia</a> page on Wikidata presents Scholia briefly. <a href="http://www2.imm.dtu.dk/pubdb/views/edoc_download.php/7010/pdf/imm7010.pdf"><em>Scholia, Scientometrics and Wikidata</em></a> is our canonical scientific article about Scholia.
