stringdist_join results in NAs

耗尽温柔 提交于 2020-06-27 12:21:30
问题 i am experimenting with the stringdist package in order to make fuzzy joins and i run into a problem which i do not understand and fail to find an answer for. I want to join these 2 data tables with the "dl" method and it produces a NA, which i completely do not understand. Maybe one of you has an explanation for this. The code: library(fuzzyjoin) test1<-as.data.frame(test1<-c("techniker")) test2<-as.data.frame(test2<-c("technician")) setnames(test2,1,"label") setnames(test1,1,"label") x <-

Fuzzy smart number parsing in Python

血红的双手。 提交于 2020-05-28 06:04:12
问题 I wish to parse decimal numbers regardless of their format, which is unknown. Language of the original text is unknown and may vary. In addition, the source string can contain some extra text before or after, like currency or units. I'm using the following: # NOTE: Do not use, this algorithm is buggy. See below. def extractnumber(value): if (isinstance(value, int)): return value if (isinstance(value, float)): return value result = re.sub(r'&#\d+', '', value) result = re.sub(r'[^0-9\,\.]', '',

原文: 十九种Elasticsearch字符串搜索方式终极介绍 前言 刚开始接触Elasticsearch的时候被Elasticsearch的搜索功能搞得晕头转向,每次想在Kibana里面查询某个字段的时候,查出来的结果经常不是自己想要的,然而又不知道问题出在了哪里。出现这个问题归根结底是因为对于Elasticsearch的底层索引原理以及各个查询搜索方式的不了解,在Elasticsearch中仅仅字符串相关的查询就有19个之多,如果不弄清楚查询语句的工作方式,应用可能就不会按照我们预想的方式运作。这篇文章就详细介绍了Elasticsearch的19种搜索方式及其原理,老板再也不用担心我用错搜索语句啦! 简介 Elasticsearch为所有类型的数据提供实时搜索和分析,不管数据是结构化文本还是非结构化文本、数字数据或地理空间数据,都能保证在支持快速搜索的前提下对数据进行高效的存储和索引。用户不仅可以进行简单的数据检索,还可以聚合信息来发现数据中的趋势和模式。 搜索是Elasticsearch系统中最重要的一个功能,它支持结构化查询、全文查询以及结合二者的复杂查询。结构化查询有点像SQL查询,可以对特定的字段进行筛选,然后按照特定的字段进行排序得到结果。全文查询会根据查询字符串寻找相关的文档,并且按照相关性排序。 Elasticsearch内包含很多种查询类型
