synonym

问题 I am trying to identify near duplicate entries of names in a database. I am new to databases, however i am familiar with R. I can get clusters of near duplicates using fuzzy matching and soundex in R. However there are several names which are synonyms of each other. I would like to cluster the names based on this criteria along with the above ones. I want to do as suggested in Techniques for finding near duplicate records but with synonyms. I understand there is a sort of database of synonyms

问题 I am doing index time synonym expansion for multi word synonyms. In my synonyms.txt I have synonyms like (barc=>barc,bhabha atomic research center). But when I am searching for "barc" it is not highlighting "bhabha atomic research center". Only 1st word i.e "bhabha" is highlighting... Can any one help me??? thanks... 回答1: For now easiest way to fix this is to set LUCENE_33 instead of LUCENE_40 in solrconfig.xml and reindex. Highlighting will work then as expected. A patch is now available:

问题 I have a webpage which contains a form, like the following: <Form action=”search.php” method=”POST”> <fieldset> <legend> Enter your search below </legend> <textarea name=”query”> </textarea> </fieldset> </form> The users text is read from query and search results are displayed using code in the following section: if ($_POST['query']) { //Users query is read and results from a search API are displayed } The next thing that happens is that a list of synonyms are generated, stored in a

问题 I am new to Lucene and I'm trying to use WordnetSynonymParser to expand queries using the wordnet synonyms prolog. Here is what I have till now: public class CustomAnalyzer extends Analyzer { @Override protected TokenStreamComponents createComponents(String fieldName, Reader reader){ // TODO Auto-generated method stub Tokenizer source = new ClassicTokenizer(Version.LUCENE_47, reader); TokenStream filter = new StandardFilter(Version.LUCENE_47, source); filter = new LowerCaseFilter(Version

问题 I'm using flyway for a long time now. Very nice/complete tool! I'm actually facing an unexpected situation... I have two schemas: An Owner pocessing the tables and sequences A User using synonyms to access the Owner objects The custom does not want me to give the 'grant create any synonym / drop any synonym' rights to the Owner. But I can provide the 'grant create synonym' to the User. So I need to Create the tables/sequences (connected with the Owner) Grant Select, Delete... to my User

问题 I've created a package that contains a stored procedure that I plan to invoke from a separate application. The stored procedure will return a sorted list of all the views and tables in the schema. To do that, it performs a simple select on the DBA_TABLES and DBA_VIEWS synonyms, as shown below: CREATE OR REPLACE PACKAGE BODY TITAN_ENTITY AS PROCEDURE GETSCHEMAOBJECTS (RESULTS IN OUT T_CURSOR) IS V_CURSOR T_CURSOR; BEGIN OPEN V_CURSOR FOR SELECT 'T' OBJECTTYPE, TABLE_NAME OBJECTNAME FROM DBA

问题 I'm trying to create a simple script to dump the results of a complex view out into a table for reporting. I have used synonyms to simplify tweaking the view and table names. The idea is that the user of the script can put the name of the view they want to use as the source, and the name of the target reporting table in at the start and away they go. If the table doesn't exist then the script should create it. If the table already exists then the script should only copy the records from the

问题 I'm developing a set of synonyms, where you can find some multi-word expressions, such as: black berry => blackberry At the analysis stage, and using the /admin/analysis.jsp tools, I can see that the results are correct.

问题 I'm trying to make a method which can check whether a given phrase matches at least one item from list of phrases and returns them. Input is the phrase, a list of phrases and a dictionary of lists of synonyms. The point is to make it universal. Here is the example: phrase = 'This is a little house' dictSyns = {'little':['small','tiny','little'], 'house':['cottage','house']} listPhrases = ['This is a tiny house','This is a small cottage','This is a small building','I need advice'] I can create
