# Term Synonyms

### Description
Produces a list of term synonyms, constructed from the given term list.
It assumes synonyms to be modeled as anonymous sets where terms in each sets are synonyms with each other:
- `(synset1, synonym, mb)`
- `(synset1, synonym, megabyte)`
- `(synset2, synonym, gb)`
- `(synset2, synonym, gigabyte)`


### Input
- `DS [OBJ]`: the dataset where synonym relations are defined.
- `SOURCE [STRING]`: a list of strings (single-token strings are expected)

### Output
- `PAIRS [STRING,STRING]`: pairs of original terms and their synonyms.
  The original terms are not included here unless they have a synonym defined.
- `EXPANDED [STRING]`: the original terms (always present) + the synonyms found.

### Parameters
- `Property`: the string property to identify synonyms. Default is `synonym`.
- `Use sub-properties`: when set to `true`, the values of all sub properties are also included. Sub-properties can be defined in the data with the `rdfs:subPropertyOf` relation.
- `Language`: when a language is selected, only the strings in this language are extracted. This uses the language tags that are defined in the data.
- `Stemming`: tokens can be stemmed for a specific language or left as they are
- `Case-sensitive`: if set to `false`, upper/lower case is ignored
