  • 1.  Help on Creating a Matchrule in console UI (advanced editor)

    Posted 10-13-2021 08:17
    Hi, 
    I am trying to construct/create a matchrule through the console using Datamodeler UI.
    What I want to achieve is to have a matching rule that  compare the three first characters of entities attribute "name". 
    Based on an exact match for these three letters/characters if true they should be flagged as potential mathces if not they should not be visible in potential matches facet.
    example:
    For the first five i want them to be potential matches for each other. Based on all five having first three letters "RUS"

    Can anyone help me with how to set this up?

    I've tested the below match rule which generates a positive match on records with the same 7 characters at the end of an account number.  You should be able to change the regex to "^\\w{3}", but I have not tested it.

    You can actually test and see the match tokens which will be generated by a configuration without deploying it using this API / tool:

    https://developer.reltio.com/private/swagger.htm?module=Data%20Operation#/Match/generateMatchTokens

    {
          "uri":"configuration/entityTypes/CustomerOrganization/matchGroups/Right7AccountNumber",
          "label":"Exact Right(Account Number,7)",
          "type":"suspect",
          "useOvOnly":"false",
          "rule":{
            "exact":[
              "configuration/entityTypes/CustomerOrganization/attributes/AccountNumber"
            ],
            "matchTokenClasses":{
              "mapping":[
                {
                  "attribute":"configuration/entityTypes/CustomerOrganization/attributes/AccountNumber",
                  "parameters":[
                    {
                      "parameter":"groups",
                      "values":[
                        {
                          "pattern":"\\w{1,7}$",
                          "className":"com.reltio.match.token.ExactMatchToken"
                        }
                      ]
                    }
                  ],
                  "class":"com.reltio.match.token.CustomMatchToken"
                }
              ]
            },
            "comparatorClasses":{
              "mapping":[
                {
                  "attribute":"configuration/entityTypes/CustomerOrganization/attributes/AccountNumber",
                  "parameters":[
                    {
                      "parameter":"groups",
                      "values":[
                        {
                          "pattern":"\\w{1,7}$",
                          "className":"com.reltio.match.comparator.BasicStringComparator"
                        }
                      ]
                    }
                  ],
                  "class":"com.reltio.match.comparator.CustomComparator"
                }
              ]
            }
          },
          "scoreStandalone":15,
          "scoreIncremental":30
        }

    Thanks, was able to make it work for entities that only contain letters.
    What corrections in matchrule would you recommend for also getting true for entities that starts with for example ("B-B") cause i notice that exciting matchrule does not trigger true on those entities.

    Regard & Thanks

    You would just need to change the regular expression.  For the first three characters of the field, I think you can use "^..."

    To confirm, I tested the tokenizer API at:

    https://{{environment}}.reltio.com/reltio/tools/matching/matchTokens

    {
    "fuzzy": false,
    "matchTokenClass": {
        "class": "com.reltio.match.token.CustomMatchToken",
             "parameters": [
                    {
                        "parameter": "groups",
                        "values": [
                            {
                                "pattern": "^\\w{3}",
                                "className": "com.reltio.match.token.ExactMatchToken"
                            }
                        ]
                    }
                ]
    },
    "values": [
        "Russian Export",
        "Russian Import"
    ]
}

Results:

[
    {
        "tokens": [
            "rus"
        ],
        "value": "Russian Export",
        "total": 1
    },
    {
        "tokens": [
            "rus"
        ],
        "value": "Russian Imoprt",
        "total": 1
    }
]
