Open repositories: value added services The Socionet example Sergey Parinov, CEMI RAS and euroCRIS
From separate open repositories to research e-infrastructure There is a general tendency of evolution when separate services are converted into integrated infrastructure, e.g. electricity, finance, transportation, etc. Such transition for heterogeneous and distributed open repositories means an establishing of a research e-infrastructure, which connects repositories as nodes and provides numerous value-added services
Basic e-infrastructure services: Socionet example 1.Information hub 2.Scientific data and information space (DIS) 3.Online workbench (academic assets managing, scientific reuse, semantic linkages, etc.) 4.Monitoring of DIS changes, including tracing of linkages all types 5.Scientometrics, including basic research assessment data
Socionet information hub (IH): how it works Harvesting heterogeneous metadata from repositories as IH input and providing standardized metadata at IH output for external reuse/processing by software agents through RSS, OAI-PMH or customized protocols Socionet IH is synchronizing a federation of about 1200 repositories/archives with about 4500 thematic collections contained about 1.1 ml metadata records
Socionet information hub: added values for repositories including your local metadata into competitive environment for its external reuse, processing and producing of new products/services, e.g. DIS building completing and improving of local repositories by using external content and services building various networks of linkages among federated metadata that enrich initial contents creating local tools/services, which expand on and process whole federated metadata etc.
Socionet scientific data and information space (DIS) Visualization of full IH contents as structured system of scientific information objects, including navigation and search Interfacing of federated metadata with research e-infrastructure services, e.g. with tools to make thematic linkages over federated metadata and for other usage Visualization of relations and linkages between DIS objects, including semantics
Socionet online workbench Personalized set of tools: –to create, manage and submit to IH->DIS collections of academic materials (in 2010 - 16 types and for all science disciplines) –to create and manage networks of semantic linkages between DIS information objects, including usage links with cited materials –to set up a personal information robot for notifications and reporting –etc.
Proposed usage metrics (1) the cited research result (or just a citation) is a basement for authors output; (2) the citation approves (or is approved by) authors output; (3) the citation illustrates of (or has another logical connection with) authors output; (4) the citation is wrong or disproved by authors output
Networks of semantic linkages At least three types of semantic networks arise within scientific DIS: –Usage linkages (what, by whom, in what sense were used in research) –Scientific inference linkages (what scientific statements are the basis, with what logical relation) –Other types of relations (language versions, etc.)
DIS monitoring services Automated monitoring of all changes in structure of information objects and linkages between them, including: –Notifications of researchers about important changes (improve scientific circulation) –Accumulating of scientometric database (improve statistic on research performance)
Linkages support services Monitoring services trace and informs: –the author who is changing his/her article, if the article has cited in other articles, that she/he can violate (by this action) links and citations that have established with the changed fragments of the article; –the authors of articles, if their articles include citation links to the changed article, about a fact of made changes in the cited article, so they should reconsider and, if it necessary, to correct corresponding citations; –the readers of electronic article that certain citations in reading text can be violated because of the cited articles were changed, and an author of the reading article has not updated suspicious citations
Scientometric services Scientometric services collect data: –usual quantitative characteristics of researchers/organizations and results of their activity; –quantitative data about all existed relations between information objects, e.g. number of persons linked with organization, number of publications linked with a person, number of citations linked with a publication, and so on; –qualitative data about all existed relations between information objects, as a graph with semantic values assigned to each edge of the graph, e.g. a set of relations with the semantic value "member of staff" between an organization and persons; a set of relations with the semantic value "basement" between a publication and citations; and so on; –data about views/downloads aggregated for each information objects according linkages, e.g. numbers of views/downloads for all publications related with a person or a sum of these numbers for all persons related with an organization and so on
Basic research assessment data Personal data or a researcher's profile presented as a complex information object of DIS with existed network of semantic linkages to other information objects (organizations, research results in different forms, events, etc.), including a history of changes of this data. Growth characteristics of this complex information objects as time series, e.g. numbers of produced by this person research results (new objects-for- reuse/papers/articles/patents, etc.), and also a numbers of usage facts for the results (like a traditional citation index). Usage activity characteristics of a researcher as a number of citations made by the researcher, including a distribution of usage characteristics, which were specified by the researcher as quality attributes of have made citations. Usage/impact characteristics for researcher's outputs/results built as a distribution of quality attributes for citations made by other scientists for researchers materials
Conclusion Open repositories users will benefit if European research e-infrastructure provides following key value added components: 1.information hub 2.unified scientific DIS 3.tools to build networks of semantic linkages over DIS objects 4.monitoring services, including linkages tracing 5.public scientometrics, including basic research assessment data
