-==== Match Key Column ====
+==== Match vs Score ====
-This column allows you to specify your matching engine.
+This section describes the difference between including groups for scoring vs including groups for scoring.
-There are six options available:
+{{ :admin_functionality:create_session:include_for_matching.png?800 |}}
-  * DQ Fonetix (Recommended)
+Include for matching - This will include a match group, along with its attributes, in the matching process.
-  * DQ Metaphone
-  * DQ Soundex
-  * Metaphone
-  * SoundEx
-  * No MatchKey
-----
+Do not include for matching - This will not feed the match group to the match engine, however once duplicate records are grouped, this data will be used for scoring records.
-==== Include For Matching Column ====
-Each group has a checkbox, if you disable matching for a group, it will not be used in the search for duplicates but will still be used to assess its overall duplicate score.
+E.g Email could be used for matching where sales@dqglobal.com returns multiple duplicate records. However when the data is scored with a score group 'Name' including the attributes 'First Name' & 'Last Name', the records will not score as duplicates upon scoring of these values. This setup would look like this:
-**Note:** At least one group must be included for matching.

+===== Match Key =====
-===== Cross Entity  Configuration=====
+You can set the ‘Match Key’ for each group with the help of drop-down selection. The 'Match Key' is used to select an algorithm for phonetic match token generation. The 'Match Key' drop-down will have six choices:
-===== Miscellaneous Functions =====
+==== Soundex ====
-This section allows you to setup the groups that will be used for matching and scoring of duplicates.
+Soundex retains the first letter of the input string to formulate its match token. Soundex removes vowels (a, e, i, o, u) and h and w from the input string. The remaining letters are assigned numbers using a lookup table to produce a token of 4 characters.
-You will see a screen similar to this:
+This means ‘Cathy’ and ‘Kathy’ will not match as their match tokens begin with a ‘C’ from Cathy and a ‘K’ from Kathy. As such, Soundex does not match well where the start of a word sounds the same but is not the same.
+Also, due to the numeric substitution it is possible to be shown non-matches (false positive) matches.
-**Note:** However this will vary depending on entity and the default groups you have setup.
+{{ :admin_functionality:settings:kathy.png?nolink&600 |}}
-{{ :admin_functionality:create_session:step_2_1.png?nolink&600 |}}
+==== DQSoundex ====
-**Matching Language:** When creating these groups you have the option to choose the matching language. The following can be used:
+DQSoundex overloads Soundex with the advanced capabilities of DQFonetix™. This improves the start of word logic and modifies the first letter(s) of an input string. DQSoundex will de-pluralise and pre-process the start of words to manage variances like ‘C’ to ‘K’ as in 'Cathy' and 'Kathy', as well as ‘Ph’ as in Phonetix to ‘F’ in Fonetix.
-  * English
+==== Metaphone ====
-  * French
-  * German
-  * Italian
-  * Spanish
-This option is located:
+Metaphone improves the Soundex algorithm by using information about variations and inconsistencies in English spelling and pronunciation, to produce a more accurate encoding.
+This allows you to find more precise matches than the simple Soundex algorithm. Metaphone considers a larger set of character transformations than Soundex and therefore analyses a string phonetically with far more accuracy.
-{{ :admin_functionality:create_session:step_2_2.png?nolink |}}
+==== DQMetaphone ====
-**Display Attributes by:** This is located just below the language drop-down, and allows you to filter the display names between the database 'Schema Name' and a user friendly 'Display Name'.
+DQMetaphone like DQSoundex is an enhanced Metaphone technology with the advanced capabilities of DQFonetix™. This improves the start of word logic and modifies the first letter(s) of an input string. DQSoundex will de-pluralise and pre-process the start of words to manage variances and improve matching.
-**Display Attributes Sorting:** The displayed attributes can also be sorted in:
+In the case shown below (Christopher), Metaphone would have generated three of five names matches. However, after running DQ’s advanced algorithms and advanced logic, DQMetaphone allows ‘Kh’ from 'Khristopher' to match with the ‘Ch’ from 'Christopher'. Thus generating the same match key token.
-  * Ascending A-Z
+{{ :admin_functionality:settings:christopher.png?nolink&600 |}}
-  * Descending Z-A
-This is done by using the drop-down menu available on the 'Entity Attributes' title.
+==== DQFonetix™ ====
-{{ :admin_functionality:create_session:step_2_3.png?nolink |}}
+DQFonetix™ contains our advanced phonetic algorithms developed over the last 25 years by DQ Global. The algorithm is property DQ Global and hence we do not share the specification of the process. However, DQPhonetix™ has four key features:
-**Note:** On this same menu under the 'Columns' option, you can also turn on or off the 'Attribute Icons' and title's.
+  * Five spoken languages – English, Spanish, French, Italian and German
+  * Avoids false matches
+  * Overcomes character variances
+  * Deals with diacritics
-**Hover Actions:**
+DQPhonetix™ provides your CRM system with the most varied matching window to highlight duplicate matches that may not be picked up – or falsely matches - in Soundex and Metaphone.
-  * Hovering over an attribute in 'Display Name' mode will give a tool-tip containing that attributes 'Schema Name' and vice versa when in 'Schema Name' mode.
+==== No Match Key ====
-  * Hovering over an attribute's icon will give a tool-tip containing the type of that attribute.
-**Attribute Searching:** You can filter down the list of attributes by using the search icon:
+Selecting no match key will not generate a phonetic token, hence no match token will be generated. However, this allows you to match identical strings.
-{{ :admin_functionality:create_session:step_2_4.png?nolink |}}
+**Include for Matching:** With the help of a checkbox feature, you can configure the ‘Include for Matching’ to select the attributes to be used for matching purposes. By default, the group is included for matching. You do have the option to uncheck the group and mark it as excluded. The groups which are not included for matching are still used for percentage scoring.
-**Note:** You must search by the title of the display mode you are in.

+  * Very High
+  * High

-{{ :admin_functionality:create_session:step_4_2.png?nolink |}}
+{{ :admin_functionality:create_session:include_for_matching.png?800 |}}
-**Skip to Start:** This is only applicable to Cloned sessions.
+Include for matching - This will include a match group, along with its attributes, in the matching process.
-{{ :admin_functionality:create_session:step_4_3.png?nolink |}}
+Do not include for matching - This will not feed the match group to the match engine, however once duplicate records are grouped, this data will be used for scoring records.
-**Next:** This will direct you to step 3.
+E.g Email could be used for matching where sales@dqglobal.com returns multiple duplicate records. However when the data is scored with a score group 'Name' including the attributes 'First Name' & 'Last Name', the records will not score as duplicates upon scoring of these values. This setup would look like this:
