Das Berliner Datenportal daten.berlin.de (online seit 2011) macht die Datenbestände der Berliner Verwaltung für die Öffentlichkeit auffindbar. Alle Berliner Behörden (Senatsverwaltungen, Bezirke, landeseigene Betriebe etc.) sind seit 2016 nach §13 des E-Government-Gesetzes Berlin verpflichtet, die Daten "in einem zentralen Datenportal" bereitzustellen, "die sie in Erfüllung ihres öffentlichen Auftrags im Rahmen ihrer jeweiligen Zuständigkeit erstellt haben und die in maschinenlesbaren Formatendoi:10.5281/zenodo.3514690 fatcat:xpjkmivv4ba65f5ngpflik6hy4

Die veröffentlichten Daten (Oktober 2019: 2150 Datensätze) sind stark heterogen: sie decken unterschiedliche thematische Bereiche ab, haben unterschiedliche Datentypen (Statistiken, Karten, Sensordaten, Protokolle etc.) und unterschiedliche Formate (Excel, CSV, XML, JSON etc.) und werden auf unterschiedliche Weise ausgeliefert (statisch, via API). Das Datenportal ist ein reines Metadatenportal: nur Metadaten sind dort durchsuchbar; die eigentlichen Datenressourcen werden dezentral und eigenverantwortlich von den jeweiligen Behörden veröffentlicht. Die Metadaten folgen einem einheitlichen Metadatenschema, das Aspekte abdeckt wie eine thematische Kategorisierung, Herkunft ("veröffentlichende Stelle") und Kontakt, geografische und zeitliche Bezüge oder auch eine Freitextbeschreibung. Es sind ausschließlich offene Lizenzen zugelassen, insbesondere Creative Commons Lizenzen oder Varianten der Datenlizenz Deutschland. Das Portal wird auf einer Kombination aus der CKAN Datenkatalog-Software und dem Drupal CMS betrieben. Als Schnittstellen sind die CKAN API (lesen und schreiben), sowie DCAT-AP.de (nur lesen) verfügbar. Nutzende des Datenportals können z. B. die Zivilgesellschaft (Transparenz, Partizipation, Forschung etc.) und die Wirtschaft (Daten als digitale Infrastruktur) sein, aber auch die Verwaltung selbst (Kollaboration zwischen Behörden, Optimierung von Prozessen).

A typical computer user's desktop contains large amount of formal data, such as addresses, events or bibliopraphies. Especially within a corporate or organizational environment, it is often important to exchange this data between employees. However, state-of-the-art communication technologies such as email or bulletin boards don't allow to easily integrate desktop data in the communication process, with the effect that the data remains locked within a user's computer. In this paper, we proposedblp:conf/semweb/MollerD05 fatcat:fz2dmaffdjal5iohdwwnyge23q

We discuss a number of preconditions which must be met in order to allow semantic blogging and encourage users to author a semantic blog, and we present a prototype of the semiBlog editor, which was created with the purpose of user-friendly semantic blogging in mind. We argue that such a semantic blog editor should integrate tightly with a user's desktop environment, as this would make integration of existing data into the blog as easy as possible.
The ability to ingest particles is lost during conjugation in the ciliate Tetrahymena. Since ingestion does not resume until the late stages of development (several hours after pair separation), differential particle uptake can be exploited to isolate conjugating cells. A magnetic separation method is presented which should be applicable to many cellular systems. Pure preparations of mating Tetrahymena make possible molecular studies on the development of this organism.doi:10.1007/bf02906529 fatcat:iaaniyrxpfgjngwcmecakof3jm
Semantic Wikis allow users to semantically annotate their Wiki content. The particular annotations can differ in expressive power, simplicity, and meaning. We present an elaborate conceptual model for semantic annotations, introduce a unique and rich Wiki syntax for these annotations, and discuss how to best formally represent the augmented Wiki content. We improve existing navigation techniques to automatically construct faceted browsing for semistructured data. By utilising the Wikidblp:conf/semwiki/OrenDMVH06 fatcat:iicgwkx6r5gmzmm66t3jkpozye

The FAST gadget development environment allows users to graphically compose intelligent, i.e., semantically annotated gadgets from predefined building blocks and deploy them on various mashup platforms, thus enabling the interconnection of different systems and services. In an environment where different parties use different ontologies to describe such building blocks, ontology matching is crucial. This paper discusses first steps in our effort to integrate ontology matching in andoi:10.1007/978-3-642-16132-2_54 fatcat:l2uughsjrff4xp365sqfyvn254

In this paper we present a solution for "weaving the claim web", i.e. the creation of knowledge networks via so-called claims stated in scientific publications created with the SALT (Semantically Annotated L A T E X) framework. To attain this objective, we provide support for claim identification, evolved the appropriate ontologies and defined a claim citation and reference mechanism. We also describe a prototypical claim search engine, which allows to reference to existing claims and hence,doi:10.1007/978-3-540-76298-0_15 fatcat:rx76zgkklffdfmnrzmi3zyd7pu

In this paper we present Konduit, a desktop-based platform for visual scripting with RDF data. Based on the idea of the semantic desktop, non-technical users can create, manipulate and mash-up RDF data with Konduit, and thus generate simple applications or workflows, which are aimed to simplify their everyday work by automating repetitive tasks. The platform allows to combine data from both web and desktop and integrate it with existing desktop functionality, thus bringing us closer to a convergence of Web and desktop.dblp:conf/esws/DraganMHAT09 fatcat:yhe35aaahjeflgxgm3273eqc2e
The USEWOD2011 workshop investigates combinations of usage data with semantics and the web of data. The analysis of usage data may be enhanced using semantic information. Now that more and more explicit knowledge is represented on the Web, the question arises how these semantics can be used to aid large scale web usage analysis and mining. Conversely, usage data analysis can enhance semantic resources as well as Semantic Web applications. Traces of users can be used to evaluate, adapt ordoi:10.1145/1963192.1963324 dblp:conf/www/BerendtHHLMV11 fatcat:tmp7xg2apndwjl2etdta5ug3zi

Also, new ways of accessing information enabled by the Web of Data imply the need to develop or adapt algorithms, methods, and techniques to analyze and interpret the usage of Web data instead of Web pages. The USEWOD2011 program includes a challenge to the workshop participants: three months before the workshop two datasets consisting of server log files of Linked Open Data sources were released. Participants are invited to come up with interesting analyses, applications, alignments, etc. for these datasets.

The Semantic Web, especially in the light of the current focus on its nature as a Web of Data, is a data-centric system, and arguably the largest such system in existence. Data is being created, published, exported, imported, used, transformed and re-used, by different parties and for different purposes. Together, these actions form a lifecycle of data on the Semantic Web. Understanding this lifecycle will help to better understand the nature of data on the SW, to explain paradigm shifts, todoi:10.3233/sw-2012-0060 fatcat:czqz3tmkufb5zin3g6vbf2kjke

However, while conceptualisations of many aspects of the SW exist, no exhaustive data lifecycle has been proposed. This paper proposes a data lifecycle model for the Semantic Web by first looking outward, and performing an extensive survey of lifecycle models in other data-centric domains, such as digital libraries, multimedia, eLearning, knowledge and Web content management or ontology development. For each domain, an extensive list of models is taken from the literature, and then described and analysed in terms of its different phases, actor roles and other characteristics. By contrasting and comparing the existing models, a meta vocabulary of lifecycle models for data-centric systems -the Abstract Data Lifecycle Model, or ADLM -is developed. In particular, a common set of lifecycle phases, lifecycle features and lifecycle roles is established, as well as additional actor features and generic features of data and metadata. This vocabulary now provides a tool to describe each individual model, relate them to each other, determine similarities and overlaps and eventually establish a new such model for the Semantic Web.
When copying and pasting data between applications using the operating system clipboard, the semantics of the transfered information is usually lost. Using Semantic Web technologies these semantics can be explicitly defined in a machine process-able way and therefore be preserved during the data transfer.

The workshop on Usage Analysis and the Web of Data (USEWOD2011) was the first workshop in the field to investigate combinations of usage data with semantics and the Web of Data. Questions the workshop aims to address are for example: How can semantics help in understanding usage data, how can semantic information be derived from usage data, and how can we learn about usage of and on the emerging Web of Data, and what can we learn from it? We report on the findings and results of this workshopdoi:10.1145/1988852.1988864 fatcat:bqookenq5najpk3klifexxlhwe
