Аннотация:There are several projects in the research community to make the citation data extracted from research papers more re-usable. This paper presents results from the CyrCitEc project to create a publicly available source of open citation content data extracted from PDF papers available at a research information system. To reach this aim the project team has created four outputs: (1) an open source software to parse papers’ metadata and full text PDFs; (2) an open service to process papers’ PDFs to extract citation data; (3) a dataset of citation data, including citation contexts (currently mostly for papers in Cyrillic); and (4) a visualization tool that provides users insight into the citation data extraction process and gives some control over the citation data parsing quality.
