#org.bibliome.alvisnlp.modules.segmig.WoSMig
Performs word segmentation on section contents.
org.bibliome.alvisnlp.modules.segmig.WoSMig searches for word boundaries in the section contents, creates an annotation for each word and adds it to the layer targetLayerName. The following are considered as word boundaries:
- consecutive whitespace characters, including ' ', newline, carriage return and horizontal tabulation;
- the positions before and after each punctuation character defined in punctuation and balancedPunctuations, thus a punctuation character always form a single-character word, a balanced punctuation breaks a word iff the corresponding punctuation is found.
If fixedFormLayerName is defined then non-overlapping annotations in this layer will be added as is in targetLayerName, the start and end positions of these annotations are considered as word boundaries and no word boundary is searched inside.
The created annotations have the feature annotationTypeFeature with a value corresponding to the word type:
-
punctuation: if the word is a single-character punctuation;
-
word: if the word is a plain non-punctuation word.
The [eosStatusFeature](#eosStatusFeature) feature contains the end-of-sentence status of the word: -
not-eos: if the word cannot be an end of sentence;
-
maybe-eos: if the word may be an end of sentence;
-
eos: if the word is definitely an end of sentence.
Optional
Type: Mapping
Constant features to add to each annotation created by this module
Optional
Type: String
Name of the layer containing annotations that should not be split into several words.
Default value: length
Type: AnnotationComparator
Comparator to use when removing overlapping fixed form annotations.
Default value: wordType
Type: String
Name of the feature where to put the word type (word, punctuation, etc).
Default value: ()[]{}""
Type: String
Balanced punctuation characters. The opening punctuation must be immediately followed by the corresponding closing punctuation. If this parameter value has an odd length, then a warning will be issued and the last character will be ignored.
Default value: true
Type: Expression
Only process document that satisfy this filter.
Default value: fixed
Type: String
Value of the type feature for annotations copied from fixed forms.
Default value: punctuation
Type: String
Value of the type feature for punctuation annotations.
Default value: ?.!;,:-
Type: String
List of punctuations, be them weak or strong.
Default value: true
Type: Expression
Process only sections that satisfy this filter.
Default value: words
Type: String
Layer where to store word annotations.
Default value: word
Type: String
Value of the type feature for regular word annotations.
