The coreseek-3.2.13 is compatible with the sph0000- 0.9.9 configuration and can be directly used without modification. However, to better search for Chinese characters, you need to use the configuration parameters added by coreseek to set Chinese word segmentation. The following are the core configurations of Chinese word segmentation. Please read them carefully and apply them to your Configuration: Source data source name #......} Index name {# Use the Sphinx configuration directly in the follo

Borrowed from the Su Jianlin of the Great God's blog about the emotional analysis of the three article. And on this basis, the new word is added. Disable Word download link: Stop word Code Environment: python2.7 TENSORFLOW-GPU 1.0 Jieba The accuracy rate after the test is as high as 98%, the result is as follows: The code is as follows: #-*-Coding:utf-8-*-' on GTX1070, 11s round after 30 rounds of iterations, the training set accuracy rate of 98.41% dropout can not be used too much, otherwise

Some tips or notes:to make the changes of the configuration files effective, the SOLR search engine needs to be rebooted. To delete all the indexed data from the yourcorename of SOLR, run ' bin/post-c yourcorename-d ' -Create another fieldtype to add flexibility to use a different stopwords list. Add the following content to Schema.xml. and create an empty text file ' Alterstopwords.txt ' in/server/solr/conf. You can add any content to the this file

-separated string, it is simply tailored for us. Then our SQL will become SELECT * from content WHERE find_in_set (' 2 ', tags) and ID In the process of flipping through these functions, you should have been deeply aware of the MySQL designer's affirmation of separating the stored field methods with commas, because there are many ways to deal with this problem. It looks so much better, everything seems perfect, isn't it? In fact, if you have more tags, you need to create multiple SQL statements

Recently in the busy exam things, there is no time to knock code, one months also not a few days to see the code, recently saw the visual word cloud, see the Internet is also a lot of such tools,But not perfect, some do not support Chinese, some Chinese word frequency statistics are inexplicable, some do not support custom shapes, all can not customize the colorSo online search, decided to use Python to draw the word cloud, the main use is Wordcloud Library, installation only need Pip Isntall Wo

Vector Space Model The basic idea is to represent each document as a vector of certain weighted word frequencies. In order to do so, the following parsing and extraction steps are needed. Ignoring case, extract all unique words from the entire set of documents. Eliminate non-content-bearing ''stopwords ''such as ''a', ''and'', ''the'', etc. for sample lists of stopwords, see [#!

of turning over these functions, You should have deeply realized that mysql designers are certain about the storage field method separated by commas, because there are many methods designed to deal with this problem. It looks much better, and everything seems perfect, right? Actually, no. If you have more tags, you need to create multiple SQL statements, and some records have more tags associated with each other, and some have fewer tags. How can we sort them by relevance. At this time, you can

default delimiter for Full-text retrieval is punctuation and stopwords, which is what we need. Full-Text search divides the strings in match and against by commas and then matches them. It should be noted that the above SQL is just an example, and if you do this directly, you can't get any results. Reasons in the following You need to set the Tags field fulltext index (if only the test, you can not do, build index just improve performance, n
