- TextColumn
- Specify the name of the input column with contents to tokenize.
- ConvertToLowerCase
- [Optional] Specify whether to convert input text to lowercase.
- StemTokens
- [Optional] Specify whether to stem the tokens—that is, whether to apply the Porter2 stemming algorithm to each token to reduce it to its root form. Before stemming, the function converts the input text to lowercase and applies the RemoveStopWords syntax element.
- Delimiter
- [Optional] Specify a regular expression that represents the word delimiter.
- OutputTotalWords
- [Optional] Specify whether to output a column that contains the total number of words in the input document.
- Punctuation
- [Optional] Specify a regular expression that represents the punctuation characters to remove from the input text. With StemTokens ('true'), the recommended value is '[\\\[.,?\!:;~()\\\]]+'.
- Accumulate
- [Optional] Specify the names of the input columns to copy to the output table.
- TokenColName
- [Optional] Specify the name of the output column that contains the tokens.
- FrequencyColName
- [Optional] Specify the name of the output column that contains the frequency of each token.
- TotalColName
- [Optional] Specify the name of the output column that contains the total number of words in the input document.
- RemoveStopWords
- [Optional] Specify whether to remove stop words from the input text before parsing.
- PositionColName
- [Optional] Specify the name of the output column that contains the position of a word within a document.
- ListPositions
- [Optional] Specify whether to output the position of a word in list form.
- OutputByWord
- [Optional] Specify whether to output each token of each input document in its own row in the output table. If you specify 'false', then the function outputs each tokenized input document in one row of the output table.
- StemExceptions
- [Optional] Specify the location of the file that contains the stemming exceptions. A stemming exception is a word followed by its stemmed form. The word and its stemmed form are separated by white space. Each stemming exception is on its own line in the file. For example:
bias bias news news goods goods lying lie ugly ugli sky sky early earli
- StopWordsList
- [Optional, disallowed with StopWordsTable.] Specify the location of the file that contains the stop words (words to ignore when parsing text). Each stop word is on its own line in the file. For example:
a an the and this with but will
