原文 2015-10-20 07:48:51 8 1 text/ analytics/ knime

I have a set of URL from which I have to read data and execute a particular work-flow in Knime for determining word frequency. 我有一组URL，我必须从中读取数据并在Knime中执行特定的工作流程来确定词频。 However I am getting error "No column with DocumentCells found!". 但是，我收到错误消息“找不到DocumentCells的列！”。 I have attached reference image. 我已附上参考图片。 Can someone please help me with this. 有人可以帮我吗

Also I am getting following error in the HttpRetriver node saying 另外我在HttpRetriver节点中说以下错误

WARN HttpRetriever (deprecated) 0:2 Error retrieving https://www.bosch-do-it.com/gb/en/diy/knowledge/project-guides/valentine-s-day-601921.jsp : Exception java.net.UnknownHostException: www.bosch-do-it.com for URL " https://www.bosch-do-it.com/gb/en/diy/knowledge/project-guides/valentine-s-day-601921.jsp ": www.bosch-do-it.com WARN HttpRetriever（不建议使用）0：2检索https://www.bosch-do-it.com/gb/en/diy/knowledge/project-guides/valentine-s-day-601921.jsp时出错：java.net异常.UnknownHostException：网址为“ https://www.bosch-do-it.com/gb/en/diy/knowledge/project-guides/valentine-s-day-601921.jsp的 www.bosch-do-it.com ”：www.bosch-do-it.com

1 个解决方案

You need the "Strings to Document" node to use the "POS tagger" node. 您需要“文档字符串”节点才能使用“ POS标记”节点。 The "POS tagger" node needs a DocumentCell to work and the "Strings to Document" node do the job. “ POS标记器”节点需要DocumentCell才能工作，“ Strings to Document”节点可以完成此工作。
