1Frey, J. ; Streitmatter, D. ; Götz, F. ; Hellmann, S. ; Arndt, N.: DBpedia Archivo : a Web-Scale interface for ontology archiving under consumer-oriented aspects.
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.

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.
Inhalt: # 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 email@example.com
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.

3Ménard, E. ; Dorey, J.: TIIARA: a new bilingual taxonomy for image indexing.
In: Knowledge organization. 41(2014) no.2, S.113-122.
Abstract: This paper presents the final phase of a research project that aims to develop a bilingual taxonomy (English and French) for the indexing of ordinary digital images. The objective of this last stage was to ask a representative sample of image searchers to complete retrieval tasks of images indexed using the new taxonomy TIIARA to measure its degree of effectiveness and efficiency. During this experiment, a sample of 60 participants were asked to indicate where in the taxonomic structure they thought they would find each one of the 30 images shown. Respondents also completed a questionnaire intended to obtain their general opinion on TIIARA and to report any difficulties encountered during the retrieval process. The quantitative data was analyzed according to statistical methods, while the content of the open-ended questions was analyzed and coded to identify emergent themes. The findings of this ultimate phase of the research project indicated that, despite the fact that some categories still need further refining, TIIARA already constitutes a successful tool that provides access to ordinary images. Furthermore, the bilingual taxonomy constitutes a definite benefit for image searchers who are not very familiar with images indexed in English, which is still the dominant language of the Web.

München : Hanser, Carl, 2008. VIII, 440 S.
Abstract: Der Wandel, den die digitale Revolution ausgelöst hat, besteht nicht nur in ausgefeilten Suchmaschinen und neuen Geschäftsmodellen. Weit folgenreicher ist die wachsende Kluft zwischen denen, die im Sternzeichen Internet geboren sind, und jenen, für die das nicht gilt. Die Kinder einer neuen Generation, die sich ein Leben ohne Google nicht vorstellen kann, sind nun volljährig. Sie sind die ersten Digital Natives, deren Mediengewohnheiten unsere Wirtschaft, unsere Kultur, ja sogar unser Familienleben tiefgreifend verändern. Die bisher sichtbaren Veränderungen stellen dabei nur die Spitze des Eisbergs dar. Wie lebt diese global vernetzte Generation von Digital Natives? Wie unterscheiden sie sich von früheren Generationen? Wie gehen sie mit Informationen um? Wahren sie ihre Privatsphäre? Was bedeutet Identität für junge Menschen, die Online-Profile und Avatare haben? Wie müssen Unternehmen mit ihnen kommunizieren? Welche Chancen und Risiken ergeben sich für die Gesellschaft? Basierend auf aktuellen Forschungsergebnissen zeichnet dieses Buch der Internetexperten John Palfrey und Urs Gasser das Porträt einer digital geborenen Generation und gewährt faszinierende Einblicke für alle, die unsere digitale Gegenwart begreifen wollen, um zu wissen, wie die Zukunft zu gestalten ist.

5Humphrey, J.: Manuscripts and metadata : Descriptive metadata in three manuscript catalogs: DigCIM, MALVINE, & Digital Scriptorium.
In: Cataloging and classification quarterly. 45(2007) no.2, S.19-39.
Abstract: The complexity of cataloging manuscripts, particularly medieval manuscripts, has meant that these materials have remained largely inaccessible to the public. The quantity and quality of the descriptive data, the time and money it takes to catalog manuscripts, and the fragility of the materials themselves explain the dearth of searchable data on these valuable resources. Even when manuscripts have been cataloged, they have often been physically available only to a few elite scholars who are able to gain access to them. Certain institutions have embarked on projects to reverse this situation. This paper deals with three of these projects: the British Library's Digital Catalogue of Illuminated Manuscripts (DigCIM), a European consortium's database entitled Manuscripts And Letters Via Integrated Networks in Europe (MALVINE), and Columbia University's Digital Scriptorium (DS). The author explores the history of each project, compares the metadata utilized by each one through the creation of a crosswalk, and analyzes the usefulness of these catalogs to the user.

In: Journal of the American Society for Information Science. 51(2000) no.3, S.216-227.
Abstract: The recent explosion of the Internet and the WWW has made digital libraries popular. Easy access to a digital library is provided by commercially available Web browsers, which provide a user-friendly interface. To retrieve documents of interest, the user is provided with a search interface that may only consist of one input field and one push button. Most users type in a single keyword, click the button, and hope for the best. The result of a query using this kind of search interface can consist of a large unordered set of documents, or a ranked list of documents based on the freuqency of the keywords. Both lists can contain articles unrelated to the user's inquiry unless a sophisticated search was performed and the user knows exactly what to look for. More sophisticated algorithms for ranking the search results according to how well they meet the users needs as expressed in the search input may help. However, what is desperately needed are software tools that can analyze the search result and manipulate large hierarchies of data graphically. In this article we describe the design of a language-independent document classification systems being developed to help users of the Florida Center for Library Automation analyze search query results. Easy access through the Web is provided, as well as a graphical user interface to display the classification results. We also describe the use of this system to retrieve and analyze sets of documents from public Web sites
Inhalt: "We use the term 'classification' to denote the general process of identifying the subject matter of a document. We use the term 'clustering' to refer to the process of forming groups (clusters) of documents with related topics and subtopics, and visualizing those clusters"

7Bador, P. ; Rey, J.: Description of a professional activity : Modelling of the activity with the completion of a pharmacy thesis related to its terminology environment.I. Description, analysis and activity modelling.
In: Knowledge organization. 27(2000) nos.1/2, S.35-43.
Abstract: In this paper, made tip of parts 1 and 11, we investigate the complex relationships between knowledge, information and activity in order to study how a system of activity assistance can help the actor to solve his information problems. Through the example of the completion of a pharmacy thesis, we have tried, in part 1, to describe, schematize and model the successive phases that make up the whole of this activity. Our method of observation and analysis combined the observation of two students preparing their pharmacy theses, the reading of five theses and the reading of six books. We thus propose in a table form, a modelling outline that presents the sequential succession of the ten operational phases describing the completion of a pharmacy thesis following a chronological order: (1) Subject definition, (2) Documentary research, (3) Documents analysis, (4) Conceiving of the experimental strategy, (5) Experimentation, (6) Results interpretation, (7) Writing of the thesis, (8) Administrative procedures, (9) Preparation of the viva, (10) Viva. The table also presents the succession of the structural, operational, material and human elements: Referents of the activity, Subject of the activity, Location of the activity, Identification of the operations, Handled objects, and Actors. We have refined the activity analysis by drawing up a structured list, showing the organization of the terms related to the different operational phases. This work is presented in part II

In: Knowledge organization. 27(2000) nos.1/2, S.44-54.
Abstract: Following the modelling of the activity related to the completion of a pharmacy thesis, as presented in part 1, we have completed the activity analysis by drawing up a structured word list to show the terminological organization around the ten operational phases. Indeed, it seemed obvious to us that the reasoning at the root of any activity is based on words used to describe it. This terminology inventory which we called Structured Terminology Environment (STE), together with the modelling diagram, could eventually be directly used during the conceiving of a software tool specific to the studied professional activity. The STE is a thesaurus of 565 words selected on the basis of a corpus stemming from five pharmacy theses and six books, where we put the significant terms which represent the actors and actions we observed during the ten phases, as well as the handled tools. Once the terms were shared out among the ten basic operations, we structured the terminology by grouping the concepts of a same nature so that the sub-categories show a certain homogeneity around the action. We used the following basic relationships: generic/specific relationships, whole/part relationships and finally, we completed the categorization with the help of classes induced by facets (process, phenomenon, properties, material or object, tool or equipment and operating conditions.)

In: AI communications. 10(1997) nos.3/4, S.177-184.
Abstract: Analyses the role-played by discourse markers in any communication process and the complex process involved in translating them. The analysis is conducted from a pragmatic standpoint and stresses the importance of context in determining the preference for 1 marker over another. Illustrates this process, presenting examples in both French and English. Makes suggestions on parameters, which should be taken into consideration for natural language processing applications

12Corey, J.F.: ¬A grant for Z39.50.
In: Library hi tech. 12(1994) no.1, S.37-47.
Abstract: In Sept. 1990, the US Dept. of Education's Library Technology and Cooperation Grants Program awarded a three-year grant to the Florida Center for Library Automation (FCLA), an agency of the Florida State University System, to develop software adhering to the ANSI Z39.50 Information Retrieval protocol standard. The Z39.50 software was to operate over the OSI communications protocols and be integrated with FCLA's NOTIS system, which is shared by all 9 state universities in Florida. In order to test the correctness of its Z39.50 software, FCLA sought out other library software developers who would be willing to develop Z39.50 systems of their own. As part of this process, FCLA helped to found the Z39.50 Implementor's Group (ZIG), which has since gone on to improve the standard and promote Z39.50 implementations throughout much of the North American library systems marketplace. Early on in the project, it became apparent that TCP/IP would be a more heavily used communication vehicle for Z39.50 messages than OSI. FCLA expanded its design to include TCP/IP and, by the end of the grant in Sept. 1993, will have a working Z39.50 system that can communicate over both OSI and TCP/IP networks

Abstract: Nachdem sich die lokale Vernetzung von PCs auf breiter Front durchsetzen konnte, steht als nächstes der Anschluß and die weltumspannende Datenautobahn an. Dort dominierte als Transportvehikel TCP/IP, das bei PCs derzeit noch zur Sonderausstattung zählt. Mit dem rasant wachsenden Informationsangebot auf dem Internet steigt gleichzeitig die Zahl der verfügbaren TCP/IP-Pakete für Windows. Mit ihnen soll der PC problemlos Anschluß an jedes UNIX-Netz finden
