The project is set up in order to improve the infrastructure for text-based linguistic research and development by building a huge, automatically annotated German text corpus and the corresponding tools for corpus annotation and exploitation. DeReKo constitutes the largest linguistically motivated collection of contemporary German texts, contains fictional, scientific and newspaper texts, as well as several other text types, contains only licenced texts, is encoded with rich meta-textual information, is fully annotated morphosyntactically (three concurrent annotations), is continually expanded, with a focus on size and stratification of data, may be analyzed free of charge via the query system COSMAS II, serves as a 'primordial sample' from which users may draw specialized sub-samples (socalled 'virtual corpora') to represent the language domain they wish to investigate.
The GIGA (German Institute of Global and Area Studies) researchers generate a large number of qualitative and quantitative research data. On this page you will find descriptions of this research data ("metadata") as well as information about the available access options. To facilitate its reuse, and to enhance research transparency, a large part of the GIGA research data is published in datorium, a repository hosted by the GESIS Leibniz Institute for the Social Sciences: Our objective is to offer free access to as much of our data as possible, to guarantee the possibility of its citation, and to secure its safe storage. Metadata of research data that cannot be published open access due to its sensitivity is also shown on this page.
SAFER-Data is a web-based interface to the Environmental Data Archive maintained by the Environmental Research Centre (ERC) in the Environmental Protection Agency (EPA) of Ireland, who has responsibilities for a wide range of licensing, enforcement, monitoring and assessment activities associated with environmental protection. increases the ability of the public to easily find, download, and use datasets that are generated and held by the Federal Government. provides descriptions of the Federal datasets (metadata), information about how to access the datasets, and tools that leverage government datasets
The Numeric Data Services Dataverse provides access to the Cross National Time Series (Banks data), the ITERATE database, and selected survey data. The DataVerse of the Harvard's Numeric Data Services houses a curated collection of datasets to meet the research and instructional needs of the Harvard community, which are also openly accessible. Primarily social sciences.
This facility permits selective searches of some atomic data files compiled by R. L. Kurucz (Harvard-Smithsonian Center for Astrophysics). The data provided are: - vacuum wavelength (in nm) [above 200 nm calculated using Edlen, Metrologia, Vol. 2, No. 2, 1966]- air wavelength (in nm) above 200 nm- log(gf), - E [in cm-1], j, parity, and configuration for the levels (lower, upper), - information regarding the source of the data. CD-ROM 18 contains the spectrum synthesis programs ATLAS7V, SYNTHE, SPECTRV, ROTATE, BROADEN, PLOTSYN, etc. and sample runs found in directory PROGRAMS; Atomic line data files BELLHEAVY.DAT, BELLLIGHT.DAT, GFIRONLAB.DAT, GULLIVER.DAT, NLTELINES.DAT, GFIRONQ.DAT, obsolete, merged into GFALL, found in directory LINELISTS: Molecular line data files C2AX.ASC, C2BA.ASC, C2DA.ASC, C2EA.ASC, CNAX.ASC, CNBX.ASC, COAX.ASC, COXX.ASC, H2.ASC, HYDRIDES.ASC, SIOAX.ASC, SIOEX.ASC, SIOXX.ASC, found in directory LINELISTS; and my solar flux atlas for test calculations SOLARFLUX.ASC.
The Deep Carbon Observatory (DCO) is a global community of multi-disciplinary scientists unlocking the inner secrets of Earth through investigations into life, energy, and the fundamentally unique chemistry of carbon. Deep Carbon Observatory Digital Object Registry (“DCO-VIVO”) is a centrally-managed digital object identification, object registration and metadata management service for the DCO. Digital object registration includes DCO-ID generation based on the global Handle System infrastructure and metadata collection using VIVO. Users will be able to deposit their data into the DCO Data Repository and have that data discoverable and accessible by others.
This database provides theoretical values of energy levels of hydrogen and deuterium for principle quantum numbers n = 1 to 200 and all allowed orbital angular momenta l and total angular momenta j. The values are based on current knowledge of the revelant theoretical contributions including relativistic, quantum electrodynamic, recoil, and nuclear size effects.
STARK-B is a database of calculated widths and shifts of isolated lines of atoms and ions due to electron and ion collisions. This database is devoted to modeling and spectroscopic diagnostics of stellar atmospheres and envelopes. In addition, it is also devoted to laboratory plasmas, laser equipments and technological plasmas. So, the domain of temperatures and densities covered by the tables is wide and depends on the ionization degree of the considered ion. The temperature can vary from several thousands for neutral atoms to several hundred thousands of Kelvin for highly charged ions. The electron or ion density can vary from 1012 (case of stellar atmospheres) to several 1019cm-3 (some white dwarfs and some laboratory plasmas).
