Abstract

We are proud to announce DBpedia Archivo (https://archivo.dbpedia.org) an augmented ontology archive and interface to implement FAIRer ontologies. Each ontology is rated with 4 stars measuring basic FAIR features. We discovered 890 ontologies reaching on average 1.95 out of 4 stars. Many of them have no or unclear licenses and have issues w.r.t. retrieval and parsing.

Content

# Community action on individual ontologies We would like to call on all ontology maintainers and consumers to help us increase the average star rating of the web of ontologies by fixing and improving its ontologies. You can easily check an ontology at https://archivo.dbpedia.org/info. If you are an ontology maintainer just release a patched version - archivo will automatically pick it up 8 hours later. If you are a user of an ontology and want your consumed data to become FAIRer, please inform the ontology maintainer about the issues found with Archivo. The star rating is very basic and only requires fixing small things. However, theimpact on technical and legal usability can be immense.
# Community action on all ontologies (quality, FAIRness, conformity) Archivo is extensible and allows contributions to give consumers a central place to encode their requirements. We envision fostering adherence to standards and strengthening incentives for publishers to build a better (FAIRer) web of ontologies. 1. SHACL (https://www.w3.org/TR/shacl/, co-edited by DBpedia's CTO D. Kontokostas) enables easy testing of ontologies. Archivo offers free SHACL continuous integration testing for ontologies. Anyone can implement their SHACL tests and add them to the SHACL library on Github. We believe that there are many synergies, i.e. SHACL tests for your ontology are helpful for others as well. 2. We are looking for ontology experts to join DBpedia and discuss further validation (e.g. stars) to increase FAIRness and quality of ontologies. We are forming a steering committee and also a PC for the upcoming Vocarnival at SEMANTiCS 2021. Please message hellmann@informatik.uni-leipzig.de <mailto:hellmann@informatik.uni-leipzig.de>if you would like to join. We would like to extend the Archivo platform with relevant visualisations, tests, editing aides, mapping management tools and quality checks.
# How does Archivo work? Each week Archivo runs several discovery algorithms to scan for new ontologies. Once discovered Archivo checks them every 8 hours. When changes are detected, Archivo downloads and rates and archives the latest snapshot persistently on the DBpedia Databus. # Archivo's mission Archivo's mission is to improve FAIRness (findability, accessibility, interoperability, and reusability) of all available ontologies on the Semantic Web. Archivo is not a guideline, it is fully automated, machine-readable and enforces interoperability with its star rating. - Ontology developers can implement against Archivo until they reach more stars. The stars and tests are designed to guarantee the interoperability and fitness of the ontology. - Ontology users can better find, access and re-use ontologies. Snapshots are persisted in case the original is not reachable anymore adding a layer of reliability to the decentral web of ontologies.

Abstract

The Thesaurus of ERIC Descriptors, 14th Edition 2001, has been developed under the auspices of the Educational Resources Information Center (ERIC) of the National Library of Education, Office of Educational Research and Improvement (OERI), U.S. Department of Education. Its content reflects ERIC's 34 years of monitoring the educational literature. This 14th edition is the result of ERIC's continued efforts to maintain quality in its controlled vocabulary and to respond to the changing nature of education. As in previous editions, the Thesaurus reflects ERIC's response to the needs of the educational user community. ERIC remains committed to maintaining a Thesaurus that represents the definitive vocabulary for education. The 2001 edition contains 10,773 vocabulary terms, of which 5,963 are main-entry Descriptors and 4,810 are non-indexable USE references or "Dead" terms. New terms not appearing in previous editions include 206 Descriptors and 210 USE references. This edition also reflects several hundred Scope Notes and Cross-reference modifications to earlier Descriptor displays. Again as in the past, the Thesaurus revision has been made possible by the joint efforts and sound judgments of personnel throughout the entire ERIC system responding to both the literature and the users in the field. ERIC vocabulary coordinators, who, as members of the systemwide "Vocabular Review Group," oversee this effort, are listed below.

Abstract

While thousands of ontologies exist on the web, a unified sys-tem for handling online ontologies - in particular with respect to discov-ery, versioning, access, quality-control, mappings - has not yet surfacedand users of ontologies struggle with many challenges. In this paper, wepresent an online ontology interface and augmented archive called DB-pedia Archivo, that discovers, crawls, versions and archives ontologies onthe DBpedia Databus. Based on this versioned crawl, different features,quality measures and, if possible, fixes are deployed to handle and sta-bilize the changes in the found ontologies at web-scale. A comparison toexisting approaches and ontology repositories is given.

Content

""A thesaurus is a terminological control device used in translating from the natural language of documents, indexers or users into a more constrained `system language' (document language, information language)". It is also "a controlled and dynamic vocabulary of semantically and generically related terms which covers a specific domain of knowledge". The Joint INIS/EDTE Thesaurus fits this definition adopted by UNESCO.' The domain of knowledge covered by the Joint INIS/ETDE Thesaurus includes physics (in particular, plasma physics, atomic and molecular physics, and especially nuclear and high-energy physics), chemistry, materials science, earth sciences, radiation biology, radioisotope effects and kinetics, applied life sciences, radiology and nuclear medicine, isotope and radiation source technology, radiation protection, radiation applications, engineering, instrumentation, fossil fuels, synthetic fuels, renewable energy sources, advanced energy systems, fission and fusion reactor technology, safeguards and inspection, waste management, environmental aspects of the production and consumption of energy from nuclear and non-nuclear sources, energy efficiency and energy conservation, economics and sociology of energy production and use, energy policy, and nuclear law. The terms in the Joint Thesaurus are listed alphabetically. For each alphabetical entry, a "word block", containing the terms associated with this particular entry, is displayed. In the word block, terms that have a hierarchical relationship to the entry are identified by the symbols BT for Broader Term, and NT for Narrower Term; a term with an affinitive relationship is identified by RT, for Related Term; terms with a preferential relationship are identified by USE or SEE, and OF for Used For, and SF for Seen For. In case of multiple USE relationships for a forbidden term, all listed descriptors should be used to index or search a given concept. In case of multiple SEE relationships, one or more of the listed descriptors should be considered for indexing or searching this concept."

Rez. in: KO 32(2005) no.4, S.159-160 (G.J.A. Riesthuis): "This thesaurus is a revised edition of: ASIS thesaurus of information science and librarianship, edited by Jessica L. Milstead, 2nd ed. (1998). The change in the title is result of the change of the name of the ASIS (American Society of Information Science) into American Society for Information Science and Technology. Since 2002 the 2nd edition was used by Information Science Abstracts (now Information Science & Technology Abstracts). In the 2nd edition the goal of the thesaurus was formulated as "[include concepts from] information science and librarianship to a depth that will adequately support indexing in those fields with [...] related fields [...] computer science, linguistics and cognitive sciences [...]" (p. vii). The present editors started to update the thesaurus to reflect "the current state of the field and to implement it for indexing the Society's publications for the ASIS&T Digital Library" (p. v). The draft 3rd edition is used to index a great part of the Society's four publications. This means that the 3`1 edition is, more than its predecessors, based on literary warrant as far as this warrant is reflected in ASIS&T publications. The Netherlands have a descriptor, but Romania or Portugal not. The Bliss Bibliographic Classification is mentioned, but the far more often used Russian Library Bibliographical Classification (BBK) is missing. The thesaurus is presented in three parts: 1. An alphabetical listing of all terms. Here one finds the preferred and non-preferred terms with their relations denoted in the customary form (SN, BT, NT, RT, USE and UF). The ordering is word-byword. 2. An hierarchical display of the terms. This display contains the preferred terms only. 3. A permuted display of all terms. Unlike the 2nd edition, this list contains the non-preferred terms too. The thesaurus is like its predecessors a faceted one. There are seven main facets: 1. People and organizations, 2. Actions, events, and processes, 3. Physical objects, 4. Theoretical concepts and influences on information, 5. Information, information delivery formats and channels, 6. Methods of study, 7. Geographic information. The first five facets are subdivided in subfacets, the last have just one subfacet each. In total there arc 18 subfacets, referred to as "top terms" in the language of the thesaurus. This structure is not very different from the structure of the second edition, although the number of subfacets and the terminology has changed. There is one new facet "geographic information" with one subfacet: "countries and regions". In this facet one can see very clearly see that the thesaurus is based on literary warrant: only relatively few countries arc mentioned. The facet "methods of study" is expanded strongly. Under each of the top terms additional concepts are presented in a hierarchical structure. The maximum depth of the hierarchy is nine, although most subfacets have no more than four or five levels. The record for the "bibliometrics" entry shows clearly the changes. The domain and the main structure have not changed, but narrower terms not previously mentioned are added."
