Word-based pattern indicators include case-sensitive and case-insensitive indicators.

Word-based pattern indicators count the number of records for each distinct pattern and are available only with the Java engine.

You can use those indicators with the String data type only.

## Case-sensitive indicators

There are two types of case-sensitive indicators:

* The CS Word Pattern Frequency indicator evaluates the most frequent word patterns.
* The CS Word Pattern Low Frequency indicator evaluates the least frequent word patterns.

Patterns focus on words and are case sensitive:

| Pattern | Description |
| --- | --- |
| [Word] | Word starting with an uppercase character and consisting of lowercase<br>characters |
| [WORD] | Word with uppercase characters |
| [word] | Word with lowercase characters |
| [Char] | Single uppercase character |
| [char] | Single lowercase character |
| [Ideogram] | One of the CJK Unified Ideographs |
| [IdeogramSeq] | Sequence of ideograms |
| [hiraSeq] | Sequence of Japanese Hiragana characters |
| [kataSeq] | Sequence of Japanese Katakana characters |
| [hangulSeq] | Sequence of Korean Hangul characters |
| [digit] | One of the Arabic numerals: 0,1,2,3,4,5,6,7,8,9 |
| [number] | Sequence of digits |

When using the CS Word Pattern Frequency and CS Word Pattern Low Frequency indicators, the following strings are replaced with the following patterns:

| String | Pattern |
| --- | --- |
| A character is NOT a Word | [Char] [word] [word] [WORD] [char] [Word] |
| someWordsINwORDS | [word][Word][WORD][char][WORD] |
| Example123@domain.com | [Word][number]@[word].[word] |
| anotherExample8@domain.com | [word][Word][digit]@[word].[word] |
| 袁 花木蘭88 | [Ideogram] [IdeogramSeq][number] |
| Latin2中文 | [Word][digit][IdeogramSeq] |
| Latin3フランス | [Word][digit][kataSeq] |
| Latin4とうきょう | [Word][digit][hiraSeq] |
| Latin5나는 한국 사람입니다 | [Word][digit][hangulSeq] |

## Case-insensitive indicators

There are two types of case-insensitive indicators:

* The CI Word Pattern Frequency indicator evaluates the most frequent word patterns.
* The CI Word Pattern Low Frequency indicator evaluates the least frequent word patterns.

Patterns focus on words and are case insensitive:

| Pattern | Description |
| --- | --- |
| [word] | Word with lowercase characters |
| [char] | Single lowercase character |
| [Ideogram] | One of the CJK Unified Ideographs |
| [IdeogramSeq] | Sequence of ideograms |
| [hiraSeq] | Sequence of Japanese Hiragana characters |
| [kataSeq] | Sequence of Japanese Katakana characters |
| [hangulSeq] | Sequence of Korean Hangul characters |
| [digit] | One of the Arabic numerals: 0,1,2,3,4,5,6,7,8,9 |
| [number] | Sequence of digits |
| [alnum] | Alphanumeric value consisting of characters and Arabic numerals |

When using the CI Word Pattern Frequency and CI Word Pattern Low Frequency indicators, the following strings are replaced with the following patterns:

| String | Pattern |
| --- | --- |
| A character is NOT a Word | [char] [word] [word] [word] [char] [word] |
| someWordsINwORDS | [word] |
| Example123@domain.com | [alnum]@[word].[word] |
| anotherExample8@domain.com | [alnum]@[word].[word] |
| 袁 花木蘭88 | [Ideogram] [IdeogramSeq][number] |
| Latin2中文 | [word][digit][IdeogramSeq] |
| Latin3フランス | [word][digit][kataSeq] |
| Latin4とうきょう | [word][digit][hiraSeq] |
| Latin5나는 한국 사람입니다 | [word][digit][hangulSeq] |

## Word-based pattern indicators and database compatibility

The following table shows the indicators that you can select in any database:

| Indicator | Supported data types with the Java analysis engine | Supported data types with the SQL analysis engine |
| --- | --- | --- |
| CS Word Pattern Frequency | <ul> <li>Number</li> <li>Text</li> <li>Date</li> </ul> | None |
| CS Word Pattern Low Frequency | <ul> <li>Number</li> <li>Text</li> <li>Date</li> </ul> | None |
| CI Word Pattern Frequency | <ul> <li>Number</li> <li>Text</li> <li>Date</li> </ul> | None |
| CI Word Pattern Low Frequency | <ul> <li>Number</li> <li>Text</li> <li>Date</li> </ul> | None |
