SAGE Open is a new open access publication from SAGE. It will publish peer-reviewed, original research and review articles in an interactive, open access format. Articles may span the full spectrum of the social and behavioral sciences and the humanities. SAGE Open seeks to be the world’s premier open access outlet for academic research. As such, unlike traditional journals, SAGE Open does not limit content due to page budgets or thematic significance. Rather, SAGE Open evaluates the scientific and research methods of each article for validity and accepts articles solely on the basis of the research. This approach allows readers greater access and gives them the power to determine the significance of each article through SAGE Open’s interactive comments feature and article-level usage metrics. Likewise, by not restricting papers to a narrow discipline, SAGE Open facilitates the discovery of the connections between papers, whether within or between disciplines.

Swoogle is a crawler-based indexing and retrieval system for the Semantic Web — RDF and OWL documents encoded in XML or N3. Swoogle extracts metadata for each discovered document, and computes relations among them. Discovered documents are also indexed by an information retrieval system which can use either character N-Gram or URIrefs as keywords to find relevant documents and to compute the similarity among a set of documents. One of the interesting properties we compute is ontology rank, a measure of the importance of a Semantic Web document.

Xstructure – arXiv Search

arXiv ePrint Archive from Cornell University is Open access to 525,110 e-prints in Physics, Mathematics, Computer Science, Quantitative Biology, Quantitative Finance and Statistics. Among the features of Xstructure are: a) Automated generation of hierarchical classification scheme for the papers. The scheme results from classification of the papers in the arxiv database. The only input for the classification is the citation graph. The number of the levels in the hierarchy and the number of the clusters is determined by the algorithm. The algorithm creates the classification scheme, and indexes the papers by the created classification; b) The classification is used to index the new papers. We plan to rebuild the classification scheme regularly. In this way, we will take into account that appearance of new papers may lead to emergence of new themes. Detection of new themes is one of our objectives; c) A number of extra attributes (e.g. Theme name, Authority and Review Articles, etc.) for the elements (themes) of the classification (see Help); and d) Accessability of the classification in response to search requests via display options, e.g., display as Tree of Themes, and Reference (Citation) Tree. About 10% of papers from arxiv are missed in their database.
