-\section{Introduction}
-
-
-The Internet Archive releases a first version of a citation graph dataset
-derived from a raw corpus of about 2.5B references gathered from metadata and
-data obtained by PDF extraction tools such as
-GROBID\cite{lopez2009grobid}. Additionally, we consider integration with
-metadata from Open Library and Wikipedia.
-The goal of this report is to describe briefly the current contents and the
-derivation of the dataset. We expect
-this dataset to be iterated upon, with changes both in content and processing.
-
-Modern citation indexes can be traced back to the early computing age, when
-projects like the Science Citation Index (1955)\citep{garfield2007evolution}
-were first devised, living on in existing commercial knowledge bases today.
-Open alternatives were started such as the Open Citations Corpus (OCC) in 2010
-- the first version of which contained 6,325,178 individual
-references\citep{shotton2013publishing}. Other notable early projects
-include CiteSeerX\citep{wu2019citeseerx} and CitEc\citep{CitEc}. The last
-decade has seen the emergence of more openly available, large scale
-citation projects like Microsoft Academic\citep{sinha2015overview} or the
-Initiative for Open Citations\citep{i4oc}\citep{shotton2018funders}. In 2021,
-according to \citep{hutchins2021tipping} over 1B citations are publicly
-available, marking a tipping point for this category of data.
-
-\section{Related Work}
-
-There are a few large scale citation dataset available today. COCI, the
-``OpenCitations Index of Crossref open DOI-to-DOI citations'' was first
-released 2018-07-29. As of its most recent release\footnote{\url{https://opencitations.net/download}}, on
-2021-07-29, it contains
-1,094,394,688 citations across 65,835,422 bibliographic
-resources\citep{peroni2020opencitations}.
-
-The WikiCite\footnote{\url{https://meta.wikimedia.org/wiki/WikiCite}} project,
-``a Wikimedia initiative to develop open citations and linked bibliographic
-data to serve free knowledge'' continously adds citations to its database and
-as of 2021-06-28 tracks 253,719,394 citations across 39,994,937
-publications\footnote{\url{http://wikicite.org/statistics.html}}.
-
-Microsoft Academic Graph\citep{sinha2015overview} is comprised of a number of
-entities\footnote{\url{https://docs.microsoft.com/en-us/academic-services/graph/reference-data-schema}}
-with \emph{PaperReferences} being one relation among many others. As of 2021-06-07\footnote{A recent copy has been preserved at
-	\url{https://archive.org/details/mag-2021-06-07}}  the
-\emph{PaperReferences} relation contains 1,832,226,781 rows (edges) across 123,923,466
-bibliographic entities.
-
-Numerous other projects have been or are concerned with various aspects of
-citation discovery and curation as part their feature set, among them Semantic
-Scholar\citep{fricke2018semantic}, CiteSeerX\citep{li2006citeseerx} or Aminer\citep{tang2016aminer}.
-
-As mentioned in \citep{hutchins2021tipping}, the number of openly available
-citations is not expected to shrink in the future.
-
-
-\section{Dataset}
-
-We release the first version of the \emph{refcat} dataset in an format used
-internally for storage and to serve queries (and which we call \emph{biblioref}
-or \emph{bref} for short). The dataset includes metadata from fatcat, the
-Open Library Project and inbound links from the English Wikipedia. The fatcat
-project itself aggregates data from variety of open data sources, such as
-Crossref\citep{crossref}, PubMed\citep{canese2013pubmed},
-DataCite\citep{brase2009datacite}, DOAJ\citep{doaj}, dblp\citep{ley2002dblp} and others,
-as well as metadata generated from analysis of data preserved at the Internet
-Archive and active crawls of publication sites on the web.
-
-The dataset is
-integrated into the \href{https://fatcat.wiki}{fatcat website} and allows users
-to explore inbound and outbound references\cite{fatcatguidereferencegraph}.
-
-The format records source and target (fatcat release and work) identifiers, a
-few attributes from the metadata (such as year or release stage) as well as
-information about the match status and provanance.
-
-The dataset currently contains 1,323,423,672 citations across 76,327,662
-entities (55,123,635 unique source and 60,244,206 unique target work
-identifiers; for 1,303,424,212 - or 98.49\% of all citations - we do have a DOI
-for both source and target).
-The majority of matches - 1,250,523,321 - are established through identifier
-based matching (DOI, PMIC, PMCID, ARXIV, ISBN). 72,900,351 citations are
-established through fuzzy matching techniques.
-
-The majority of citations between \emph{refcat} and COCI overlap, as can be
-seen in~Table~\ref{table:cocicmp}.

-\section{System Design}
-
-The constraints for the systems design are informed by the volume and the
-variety of the data. The capability to run the whole graph derivation on a
-single machine was a minor goal as well. In total, the raw inputs amount to a
-few terabytes of textual content, mostly newline delimited JSON. More
-importantly, while the number of data fields is low, certain schemas are very
-partial with hundreds of different combinations of available field values found
-in the raw reference data. This is most likely caused by aggregators passing on
-reference data coming from hundreds of sources, each of which not necessarily
-agreeing on a common granularity for citation data and from artifacts of
-machine learning based structured data extraction tools.
-
-Each combination of fields may require a slightly different processing path.
-For example, references with an Arxiv identifier can be processed differently
-from references with only a title. Over 50\% of the raw reference data comes
-from a set of eight field set manifestations, as listed in
-Table~\ref{table:fields}.
-

-		\label{table:fields}
-	\end{center}
-\end{table}
-
-Overall, a map-reduce style\citep{dean2010mapreduce} approach is
-followed\footnote{While the operations are similar, the processing is not
-	distributed but runs on a single machine. For space efficiency, zstd\citep{collet2018zstandard} is used to compress raw data and derivations.}, which allows
-for some
-uniformity in the overall processing. We extract (key, document) tuples (as
-TSV) from the raw JSON data and sort by key. We then group documents with the
-same key and apply a function on each group in order to generate
-our target schema or perform
-additional operations such as deduplication or fusion of matched and unmatched references.
-
-The key derivation can be exact (via an identifier like DOI, PMID, etc) or
-based on a value normalization, like slugifying a title string. For identifier
-based matches we can generate the target schema directly.  For fuzzy matching
-candidates, we pass possible match pairs through a verification procedure,
-which is implemented for \emph{release entity}\footnote{\url{https://guide.fatcat.wiki/entity_release.html}.} pairs. This procedure is a
-domain dependent rule based verification, able to identify different versions
-of a publication, preprint-published pairs and documents, which are
-are similar by various metrics calculated over title and author fields. The fuzzy matching
-approach is applied on all reference documents without identifier (a title is
-currently required).
-
-With a few schema conversions, fuzzy matching can be applied to Wikipedia
-articles and Open Library (edition) records as well. The aspect of precision
-and recall are represented by the two stages: we are generous in the match
-candidate generation phase in order to improve recall, but we are strict during
-verification, in order to control precision. Quality assurance for verification is
-implemented through a growing list of test cases of real examples from the catalog and
-their expected or desired match status\footnote{The list can be found under:
-	\url{https://gitlab.com/internetarchive/cgraph/-/blob/master/skate/testdata/verify.csv}.
-	It is helpful to keep this test suite independent of any specific programming language.}.
-
-
-\section{Limitations and Future Work}
-
-As other dataset in this field we expect this dataset to be iterated upon.
-
-\begin{itemize}
-	\item The fatcat catalog updates its metadata
-	      continously\footnote{A changelog can currenly be followed here:
-		      \url{https://fatcat.wiki/changelog}} and web crawls are conducted
-	      regularly.  Current processing pipelines cover raw reference snapshot
-	      creation and derivation of the graph structure, which allows to rerun
-	      processing based on updated data as it becomes available.
-
-	\item Metadata extraction from PDFs depends on supervised machine learning
-	      models, which in turn depend on available training datasets. With additional crawls and
-	      metadata available we hope to improve models used for metadata
-	      extraction, improving yield and reducing data extraction artifacts in
-	      the process.
-
-	\item As of this version, a number of raw reference
-	      docs remain unmatched, which means that neither exact nor fuzzy matching
-	      has detected a link to a known entity. On the one
-	      hand, this can hint at missing metadata. However, parts of the data
-	      will contain a reference to a catalogued entity, but in a specific,
-	      dense and harder to recover form.
-	      This also include improvements to the fuzzy matching approach.
-	\item The reference dataset contains millions of URLs and their integration
-	      into the graph has been implemented as prototype. A full implementation
-	      requires a few data cleanup and normalization steps.
-\end{itemize}

-\section{Appendix A}
-
-
-A note on data quality: While we implement various data quality measures,
-real-world data, especially coming from many different sources will contain
-issues. Among other measures, we keep track of match reasons,
-especially for fuzzy matching to be able to zoom in on systematic errors
-more easily (see~Table~\ref{table:matches}).
