Water internet Accessible Distributed Information System (W@DIS)
The W@DIS information system is designed to provide access to data, information, and ontologies relating to quantitative spectroscopy required for solving fundamental and applied problems pertaining to a number of subject domains: atmospheric optics, astronomy, etc.
The information system under discussion is a prototype of the next generation information system on molecular spectroscopy based on Semantic Web technologies. The system focuses on spectral data representation for the end user with a possibility to employ information characterized by different levels of details both for the structure of the data and for the knowledge (semantic annotations) associated with these data. It is the end user who is to make a decision about the level of details required.
In this information system, molecular spectroscopic data are divided into three parts: parameters of energy levels, transitions, and line profiles. The first two parts are independent of temperature and intended for inner spectroscopic tasks. The data about line profiles depend on temperature and chemical components of molecular mixtures.
The use of spectral databases in solving applied problems imposes different requirements on data quality. For example, calculations of solar radiation transfer assume weaker requirements on data quality as compared to those to be met in solving the problem associated with absorption of narrow-band laser radiation. The data quality in this kind of databases determines the degree of the validity of and trust in the data. Analysis of quality of a complete set of published data and expert data acquired from this set as well as access of researchers and agents to the details contained in the results of the analysis is the problem whose solution will provide a rapid assessment of expert data quality from different sources.
Originally W@DIS was designed for storage and presentation of a complete consistent set of published spectral data on the water molecule and water isotopologues [1–4]. Then a complete consistent set of data about the hydrogen sulphide molecule was added to W@DIS [5,6]. Today W@DIS incorporates complete sets of published data for more than 20 atmospheric molecules. Completeness of data is associated not only with a set of publications, but also with information on hyperfine structure of spectra, electronic states, sets of all the broadening substances, spectral line shape models, etc.
Methodology for data-
|n the process of uploading or editing molecular data in W@DIS, a semantic annotation (ontology) on the data quality for the pertinent molecule is generated by a computer. The report is a set of semantic annotations and a system of classification of the annotations for a semantic search for the results of the analysis of the molecular data quality, using published literature on states, transitions, and trust of experts in the data of interest [7,8].
