stop-words

问题 I'm using mysql's built in boolean fulltext features to search a dataset. (MATCH... AGAINST syntax). I'm running into a problem where keywords that are in MySql's default stopwords list are not returning any results. For example, "before", "between", etc. There is (I think) no way to disable MySql's stopwords at runtime. And because I am hosting my website on a shared server (DreamHost), I dont have the option of recompiling MySQL with stopwords disabled. I'm wondering if anyone has any

问题 I am running a full-text search for my site using SQL Server 2008 R2 and freetexttable. I am getting this error when a stop word is entered: Informational: The full-text search condition contained noise word(s). So I did what everyone said to do and turned on the Transform Noise Words so the stop/noise words are ignored and the query can continue. But this changed nothing: sp_configure 'show advanced options', 1; RECONFIGURE; GO sp_configure 'transform noise words', 1; RECONFIGURE; GO I still

问题 The requirement is to capture the keywords from the user input given in chat window and make a web api call to get a file link. I have four different categories into which the user input query can be classified: --Operating Group --Technology --Geography --Themes I have configured a LUIS intent and listed these four categories as entitites. However, the issue now is that the entity list cannot be predefined since there can be any number of search keywords which can be passed to web api. I am

问题 Is it possible to include multi-word stopwords in stopfilterfactory of Solr ? If yes, kindly tell me the way. Right now first I am putting all the multiple-word stopwords in synonyms.txt file and then using one synonym for all these words in stopwords.txt , but its not working. 回答1: I give a try this kind of a syntax stopwords.txt stop word more long stop word and it looks like it working.

问题 I have written a query which will perform Full Text search using full search Index in mysql Table. But my problem is that when user searches with "to go" then it will not search anything because of stopwords in mysql. So my question is, how can I write a Full Search query which will ignore the stopwords? 回答1: To override the default stopword list, set the ft_stopword_file system variable. (See Section 5.1.4, “Server System Variables”.) The variable value should be the path name of the file

问题 I'm using LAMP on my machine and I'm using the functionality of Full-Text search in my website. I don't want to consider the by default list of "Full-Text Stopwords" during the Full-Text search. But I want to give some stopwords manually which must not be considered during Full-Text search. Can anyone tell me how should I achieve this? If you need any further information regarding the issue I can provide you the same. Thanks for understanding my issue. 回答1: As documented under Fine-Tuning

问题 I am working on a data mining algorithm where I need to tokenize the string using multiple words. I have a separate file which contain all the stopwords. What I need to do is to tokenize the input string by any of the word (stopword) working as delimiter. For eg. If the file contains stopwords as a is and of that and the input string comes to be "a computer cluster consists of a set of loosely connected computers that work together" the output comes to be computer cluster consists set loosely

问题 Here is my code: for (int i = 0; i < myarraylist.size(); i++) { for (int j = 0; j < stopwords.size(); j++) { if (stopwords.get(j).equals(myarraylist.get(i))) { myarraylist.remove(i); id.remove(i); i--; // to look at the same index again! } } } I have problem.. after element removed, all index always changed, the loop above so messy. To illustrate: I have 54 data, but loop above become messy after element removed.. so only 50 data that checked. Is there another way or fix my code to remove

问题 I have a module based on Apache Lucene 5.5 / 6.0 which retrieves keywords. Everything is working fine except one thing — Lucene doesn't filter stop words. I tried to enable stop word filtering with two different approaches. Approach #1: tokenStream = new StopFilter(new ASCIIFoldingFilter(new ClassicFilter(new LowerCaseFilter(stdToken))), EnglishAnalyzer.getDefaultStopSet()); tokenStream.reset(); Approach #2: tokenStream = new StopFilter(new ClassicFilter(new LowerCaseFilter(stdToken)),
