Bibliographic database “dblp” celebrates silver anniversary

For more than 25 years now, the dblp computer science bibliography has been indexing and supporting international computer science research. Since today, the future of the database has also been secured at the Leibniz Center for Computer Science in Schloss Dagstuhl. On this occasion, a festive colloquium will be held at the University of Trier on Friday, November 23rd, 2018. Under the motto “25 years of dblp – 2^22 entries” the database celebrates the milestone of more than 4 million indexed computer science publications. As first keynote speaker, Prof. Dr. Gerhard Weikum (Research Director of the Max Planck Institute for Computer Science in Saarbrücken and former member of the German Council of Science and Humanities) will give an insight into Read more…

External identifiers in dblp

There are now more than 60,000 manually confirmed external IDs linked with dblp author bibliographies. This is quite an improvement. Below you can see the number of external identifiers at the end of each year compared to the numbers in October 2018 As you can see, our definition of external identifier is a bit wider than usual. E.g., we include Twitter profiles here. ORCID, Google Scholar, Wikipedia and Twitter should be known to the readers. Wikidata is a LOD data store build on top of Wikpedia that provides query-able data. The others are GND: identifier from the German national Library see here ISNI: global authority file see here zbMath: biographies of Mathematicians see here Math Genealogy:   the Mathematics Genealogy Project. Stores relations between researchers Read more…

ORCID state of dblp

Since more than a year now, dblp has intensified its efforts to link dblp bibliographies to ORCIDs used by that author. ORCID information are now added regularly to the dblp data set. The primary sources for ORCIDs are: first, the annual ORCID open data dump and, second, metadata directly provided by publishers who have started to increasingly label author signatures with ORCID information. Neither of those data sources are free of errors and data hick-ups, so we are still manually cleaning the ORCID data prior to adding them to the corpus. But overall, ORCIDs have helped us to correct numerous cases of homonymous and synonymous bibliographies in dblp, so it is absolutely worth our time. Since the past big ORCID Read more…

Historical dblp file is now available

A historical version of the dblp.xml (called hdblp.xml) is now available at zenodo. hdblp contains historical revisions of all metadata records in dblp. The file can be used to reconstruct the state of dblp for each day between June 1999 and March 2018. The dblp computer science bibliography was founded in 1993. Since then, dblp has gathered (as of March 2018) data on more than 4 million publications written by about 2 million different authors. For each publication and each author, the collection maintains a simple metadata record which contains all descriptive information. The set of all records is available as daily snapshot as well as stable monthly releases. The records are modified frequently to add additional information or to Read more…
