为VO年龄准备旧的和最近的无线电源表：当前状态
Preparing old and recent radio source tables for the VO age: Current status
摘要：
独立于已建立的数据中心，部分是为了我自己的研究，我一直在收集近1500篇与无线电源有关的文章的表格数据。光学字符识别（OCR）被用来从近600个表中恢复。这些文章中只有44%的表格可以在CDS或CATS目录集合中找到。这部分是62%的文章超过100个来源。令人惊讶的是，自2001年以来以电子方式发表的文章的这些分数并没有更好，也许部分原因是表格数据通常以不适用于直接机器阅读的格式发表。Simbad和NED数据库仅识别出与现有电子无线电源列表相对应的参考文献的60%，与这些参考文献相关联的对象数量更少。需要查询NED和Simbad等对象数据库以及目录浏览器（VizieR，CATS），以获得有关射电源的最完整信息。数据中心需要更多的人力资源，作者、审稿人、编辑、出版商和数据中心之间需要更好的合作，以改善表格数据从期刊到公共数据库的流动。虚拟天文台项目目前正在努力为储存在不同地点的不同类型的已发表和档案数据提供检索和分析工具，应当通过恢复和纳入目前无法以这种方式获得的大量已发表数据的同等努力来平衡这一努力。如果能够找到人力资源，将提供作者收集的数据集，用于编制输入目录浏览器所需的元数据。
英文摘要：
Independent of established data centers, and partly for my own research, I have been collecting the tabular data from nearly 1500 articles concerned with radio sources. Optical character recognition (OCR) was used to recover tables from nearly 600 of these. Tables from only 44 percent of these articles are available in the CDS or CATS catalog collections. This fraction is 62 percent for articles with over 100 sources. Surprisingly, these fractions are not better for articles published electronically since 2001, perhaps partly due to the fact that often tabular data are published in formats not useful for direct machine reading. The databases Simbad and NED recognize only about 60 percent of the bibliographic references corresponding to the existing electronic radio source lists, and the number of objects associated with these references is much smaller still. Both, object databases like NED and Simbad, as well as catalog browsers (VizieR, CATS) need to be consulted to obtain the most complete information on radio sources. More human resources at the data centers and better collaboration between authors, referees, editors, publishers, and data centers are required to improve the flow of tabular data from journals to public databases. Current efforts within the Virtual Observatory (VO) project, to provide retrieval and analysis tools for different types of published and archival data stored at various sites, should be balanced by an equal effort to recover and include large amounts of published data not currently available in this way. If human resources can be found, the data sets collected by the author will be made available for the preparation of metadata necessary for their ingression into catalog browsers.
