    Vectorize text map features by treating low cardinality text features as categoricals and applying hashing trick to high caridinality ones.

    Vectorize text map features by treating low cardinality text features as categoricals and applying hashing trick to high caridinality ones.

    maxCategoricalCardinality

    max cardinality for a text feature to be treated as categorical

    numHashes

    number of features (hashes) to generate

    autoDetectLanguage

    indicates whether to attempt language detection

    minTokenLength

    minimum token length, >= 1.

    toLowercase

    indicates whether to convert all characters to lowercase before analyzing

    cleanKeys

    clean map keys before pivoting

    cleanText

    indicates whether to ignore capitalization and punctuation

    trackNulls

    indicates whether or not to track null values in a separate column.

    trackTextLen

    indicates whether or not to track the length of the text in a separate column

    topK

    number of most common elements to be used as categorical pivots

    minSupport

    minimum number of occurrences an element must have to appear in pivot

    unseenName

    name to give indexes which do not have a label name associated with them

    hashWithIndex

    include indices when hashing a feature that has them (OPLists or OPVectors)

    binaryFreq

    if true, term frequency vector will be binary such that non-zero term counts will be set to 1.0

    prependFeatureName

    if true, prepends a input feature name to each token of that feature

    autoDetectThreshold

    Language detection threshold. If none of the detected languages have confidence greater than the threshold then defaultLanguage is used.

    hashSpaceStrategy

    strategy to determine whether to use shared hash space for all included features

    defaultLanguage

    default language to assume in case autoDetectLanguage is disabled or failed to make a good enough prediction.

    hashAlgorithm

    hash algorithm to use

    others

    additional text features

    returns

    result feature of type Vector
