Fuzzy logic for excel data -Pandas

由 巧了我就是萌 提交于 2019-12-23 01:29:17
问题 I have two dataframes DF(~100k rows)which is a raw data file and DF1(15k rows), mapping file. I'm trying to match the DF.address and DF.Name columns to DF1.Address and DF1.Name. Once the match is found DF1.ID should be populated in DF.ID(if DF1.ID is not None) else DF1.top_ID should be populated in DF.ID. I'm able to match the address and name with the help of fuzzy logic but i'm stuck how to connect the result obtained to populate the ID. DF1-Mapping file DF Raw Data file import pandas as pd

Create a unique ID by fuzzy matching of names (via agrep using R)

问题 Using R, I am trying match on people's names in a dataset structured by year and city. Due to some spelling mistakes, exact matching is not possible, so I am trying to use agrep() to fuzzy match names. A sample chunk of the dataset is structured as follows: df <- data.frame(matrix( c("1200013","1200013","1200013","1200013","1200013","1200013","1200013","1200013", "1996","1996","1996","1996","2000","2000","2004","2004","AGUSTINHO FORTUNATO FILHO","ANTONIO PEREIRA NETO","FERNANDO JOSE DA COSTA"

问题 I am implementing a Fuzzy Date control in C# for a winforms application. The Fuzzy Date should be able to take fuzzy values like Last June 2 Hours ago 2 Months ago Last week Yesterday Last year and the like Are there any sample implementations of "Fuzzy" Date Time Pickers? Any ideas to implement such a control would be appreciated PS : I am aware of the fuzzy date algorithm spoken about here and here, I am really looking for any ideas and inspirations for developing such a control 回答1: The

Clang for fuzzy parsing C++

由 痴心易碎 提交于 2019-12-12 07:45:38
问题 Is it at all possible to parse C++ with incomplete declarations with clang with its existing libclang API ? I.e. parse .cpp file without including all the headers, deducing declarations on the fly. so, e.g. The following text: A B::Foo(){return stuff();} Will detect unknown symbol A, call my callback that deducts A is a class using my magic heuristic, then call this callback the same way with B and Foo and stuff. In the end I want to be able to infer that I saw a member Foo of class B

DAX closest value match with no relationship

由 旧巷老猫 提交于 2019-12-12 02:47:24
问题 I'm trying to migrate a report from Excel into Power BI and I'm hoping someone can help me as I'm new to DAX. I have two tables and one (let's call it table A) contains a column of planned start Date/Times for events while the other contains the actual start Date/Times of the same events. There is usually only a few minutes difference between the planned and actual start times. I need to match the closest actual start Date/Time from Table B to the planned start Date/Times in table A. There

Converting PHP Fuzzy time to Javascript?

由 浪尽此生 提交于 2019-12-12 00:33:37
问题 I have a php function to do fuzzy time (aka time ago). This is used when building a table from the server side, however now we are adding new items to the table through JavaScript, and we have the ability to select a date, therefore I need to duplicate the functionality in Javascript but have it accept the date in the format YYYY-MM-DD e.g. 2012-12-14 . I shall begin working on it, but I am terrible with dates in Javascript so have posted it here incase someone can do it faster. The function

Extracting date from a string in PHP

由 只谈情不闲聊 提交于 2019-12-11 10:04:08
问题 How can I extract the date from an arbitrary string such as "Joe Soap was born on 12 February 1981"? Python has a wonderful fuzzy parsing functionality provided by python-dateutil as described in this question. I'm looking for a library that provides the same type of functionality in PHP. 回答1: What about date_parse , but if you know your date format, just use the regex to get what you want. 来源： https://stackoverflow.com/questions/8034833/extracting-date-from-a-string-in-php

Matching fuzzy strings

问题 I have two tables that I need to merge together in PostgreSQL, on the common variable "company name." Unfortunately many of the company names don't match exactly (i.e. MICROSOFT in one table, MICROSFT in the other). I've tried removing common words from both columns such as "corporation" or "inc" or "ltd" in order to try to standardize names across both tables, but I'm having trouble thinking of additional strategies. Any ideas? Thanks. Also, if necessary I can do this in R. 回答1: Have you

你知道的越多，你不知道的越多 点赞再看，养成习惯 GitHub https://github.com/JavaFamily 上已经收录有一线大厂面试点脑图、个人联系方式和技术交流群，欢迎Star和指教 前言 这是帅丙真实事件，大家都知道很多公司都是有故障等级这么一说的，这就是敖丙在公司背的P0级故障，敖丙差点因此 被解雇 ，事情经过 十分惊心动魄 ，我的 心脏病都差点复发 。 事故等级主要针对生产环境，划分依据类似于bug等级。 P0属于最高级别事故，比如崩溃，页面无法访问，主流程不通，主功能未实现，或者在影响面上影响很大（即使bug本身不严重）。 P1事故属于高级别事故，一般属于主功能上的分支，支线流程，核心次功能等，后面还有P2，P3等，主要根据企业实际情况划分。 正文 敖丙之前也负责公司的商品搜索业务，因为业务体量增速太快了，商品表中的商品数据也很快跃入千万级别，查询的RT（response time 响应时间）也越来越高了，而且产品说需要根据 更多维度去查询商品 。 因为之前我们都是根据商品的名称去查询的，但是电商其实都会根据很多个维度去查询商品。 就比如大家去淘宝的查询的时候就会发现，你搜商品名称、颜色、标签等等多个维度都可以找到这个商品，就比如下图的搜索，我只是搜了【 帅丙 】你会发现，名字里面也没有连续的帅丙两个字，有帅和丙的出来了

Elasticsearch数据库

1、什么是Elasticsearch 1、概念以及特点 1、Elasticsearch和MongoDB/Redis/Memcache一样，是非关系型数据库。是一个接近实时的搜索平台，从索引这个文档到这个文档能够被搜索到只有一个轻微的延迟，企业应用定位：采用Restful API标准的可扩展和高可用的实时数据分析的全文搜索工具。 2、可拓展：支持一主多从且扩容简易，只要cluster.name一致且在同一个网络中就能自动加入当前集群；本身就是开源软件，也支持很多开源的第三方插件。 3、高可用：在一个集群的多个节点中进行分布式存储，索引支持shards和复制，即使部分节点down掉，也能自动进行数据恢复和主从切换。 3、采用RestfulAPI标准：通过http接口使用JSON格式进行操作数据。 4、数据存储的最小单位是文档，本质上是一个JSON 文本： 2、项目中为何使用（主搜索次分析再存储） 2.1、搜索引擎 实际项目开发中，几乎每个系统都会有一个搜索的功能，数据量少时可以直接从主数据库中比如Mysql搜索，但当搜索做到一定程度时，比如系统数据量上了10亿、100亿条的时候，传统的关系型数据库的I/O性能和统计分析性能就难以满足用户需要了。所以很多公司都会把搜索单独做成一个独立的模块，用ElasticSearch等来实现。虽然内存缓存数据库的读写性能很高
