https://elsevierlabs.github.io/OA-STM-Corpus/ OA STM Corpus A corpus, and small treebank, of Open Access journal articles from multiple disciplines in Science, Technology, and Medicine Corpus ----------- To improve this situation, Elsevier is providing a selection of 110 journal articles from 10 different STM domains as a freely-redistributable corpus. The articles were selected from our Open Access content and have a Creative Commons CC-BY license. Therefore, they are free to redistribute and use. The domains are agriculture, astronomy, biology, chemistry, computer science, earth science, engineering, materials science, math, and medicine. Currently we provide 11 articles in each of the 10 domains. For each article in the corpus we provide: * the XML source, * a simple text version for easier text mining, * several versions with different annotations. These include part of speech tags, sentence breaks, NP and VP chunks, lemmas, syntactic constituents parses, wikipedia concept identification, and discourse analysis. (Some of this is still under construction.) 相关文章： New open access resource will support text mining and natural language processing, http://goo.gl/ayB6UO --
