For the attention of all physicists. Please spread the word among physicists, astronomers, mathematicians, etc. Thanks. Arun ---- New way to browse and search arXiv Xstructure is a new way to browse and search arXiv. (Thanks to Richard Akerman.)
From the site:
Among the features of this service are: [1] Automated generation of hierarchical classification scheme for the papers. The scheme results from classification of the papers from the arxiv database. The EqRank algorithm did the classification. 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. Generally, there is no external parameters (e.g., a preset list of clusters) in the algorithm. The algorithm creates the classification scheme, and indexes the papers by the created classification; [2] 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; [3] A number of extra attributes (e.g. Theme name, Authority and Reference Articles, etc.) for the elements (themes) of the classification (see Help); [4] Accessability of the classification in response to search requests via display options, e.g., display as Tree of Themes, and Refrerence (Citation) Tree. At the moment, the service is available only for the hep-th sector of arxiv.org. Hopefully, it will be extended to cover a number of other sectors.
