@sap/textmining

@sap/textmining is a Node.js module on the XS Advanced platform that supports text mining. Text mining makes determinations about the content of unstructured text documents by examining the terms used within them.

@sap/textmining is implemented as an interface to the Text Mining SQL API in HANA. The API functions and parameters follow the pattern of the Text Mining XS Classic API:
- categorizeKNN()
- getRelatedDocuments()
- getRelatedTerms()
- getRelevantDocuments()
- getRelevantTerms()
- getSuggestedTerms()
- initialize()

For more information on the Text Mining SQL API, see the SAP HANA SQL and System Views Reference section Advanced Data Processing. For initialize(), refer to the section ALTER FULLTEXT INDEX.

For more information on the Text Mining XS Classic API, see the SAP HANA Text Mining XS JavaScript API Reference.

For more information on text mining, see the SAP HANA Text Mining Developer Guide.

Usage example

``javascript
var textmining = require('@sap/textmining');
var hdb = require('hdb');
var db = {
"host": "HOST",
"port": 3XX15,
"user": "USERNAME",
"password": "PASSWORD"
}

var client = hdb.createClient({
host: db.host,
port: db.port,
user: db.user,
password: db.password
});

var p = {
inputTermText : "term",
top : 10,
threshold : 0.3
}

var config = {
client : client,
referenceTable : 'SCHEMA.TABLE',
referenceColumn : 'COLUMN'
}

var tmd = new textmining(config);
client.connect(function(err){
if(err)
{
client.end();
throw err;
return;
}
tmd.getSuggestedTerms(p, function(err, result){
if(err)
{
client.end();
throw err;
return;
}
console.log(result);
client.end();
});
});
