Usage tags

Usage tag Explanation

Normative/prescriptive compounding tags

(to govern compound behaviour for the speller, ie what a compound SHOULD BE)

The left part of a compound should be …

The default is +CmpN/SgN, so when nothing is specified, that will be used. To override that one, specify one or more of the following tags. +CmpN/SgN must be specified if also other tags are listed - unless +CmpN/SgN should not be used, for course.

Normative compounding tag Explanation
+CmpN/Sg Singular
+CmpN/SgN Singular Nominative
+CmpN/SgG Singular Genitive
+CmpN/PlG Plural Genitive

The right part of a compound requires to the left …

These tags overrule the regular tags defined above. One or more can be specified.

Normative left-governing tag Explanation
+CmpN/SgLeft Sg to the left
+CmpN/SgNomLeft etc.
+CmpN/SgGenLeft
+CmpN/PlGenLeft

This part of the component can …

Normative position tag Explanation
+CmpNP/All … be in all positions, default, this tag does not have to be written
+CmpNP/First … only be first part in a compound or alone
+CmpNP/Pref … only be first part in a compound, NEVER alone
+CmpNP/Last … only be last part in a compound or alone
+CmpNP/Suff … only be last part in a compound, NEVER alone
+CmpNP/None … not take part in compounds
+CmpNP/Only … only be part of a compound, i.e. can never be used alone, but can appear in any position

Descriptive compounding tags

Tags for compound analysis - this is what a compound actually is. We use this to research compounding patterns in the corpus.

Descriptive compounding tag Explanation
+Cmp/Sg Compounding using an unspecified singular stem
+Cmp/SgNom Compounding using nominative singular
+Cmp/SgGen Compounding using genitive singular
+Cmp/PlGen Compounding using genitive plural
+Cmp/Attr Compounding using attribute form
+Cmp/eh Compound stem in –eh, as in gaameh-gåaroje, from gaamege
+Cmp/ege Compound stem in –ege, as in gaamege-gåaroje
+Cmp/FinEDel Deletion of final e, as in voelem-gaaroeh, from voeleme
+Cmp/ShH Compounding using a short stem + h: –biejjh– (from biejjie), cf reakedsbiejjhvadtese
+Cmp/Sh Compounding using a short stem: –biejj– (from biejjie)
+Cmp/SplitR This is a split compound with the other part to the right:
“Arbeids- og inkluderingsdepartementet” => Arbeids– = +Cmp/SplitR
+Cmp/SplitL This is a split compound with the other part to the left, this is the oposite of the previous case
+Cmp Dynamic compound - this tag should always be part of a dynamic compound. It is important for Apertium and the speller (to give extra weights to compounds), and useful in other cases as well.
+Cmp/XForm Alle Cmp som ikke har en klar klassifisering
+Cmp/AttrH Alle Cmp som har en attr-h

Semantic tags

Semantic tags help disambiguation and syntactic analysis. All tags used are defined and listed below.

Multiple Semantic tags

Multiple semantic tags are written as one tag, with the different semantic values separated by an underline _.

All used combinations must be declared below, and the list must be manually maintained. The tags are ordered alphabetically, both the list and the semantic values within one tag.

Tag Explanation
+MWE multi word expressions, goes to abbr

Use the following flag diacritics to control downcasing of derived proper nouns (e.g. Finnish Pariisi -> pariisilainen). See e.g. North Sámi for how to use these flags. There exists a ready-made regex that will do the actual down-casing given the proper use of these flags.

Flag Explanation
@P.Px.add@ Giving possibility for Px-suffixes (all except from Nom 3.p)
@R.Px.add@ Requiring P.Px.add-flag for Px-suffixes (all except from Nom 3.p)
@P.Nom3Px.add@ Giving possibility for Px-suffixes Nom 3.p
@R.Nom3Px.add@ Requiring P.Nom3Px.add flag for Px-suffixes Nom 3.p
@P.Pmatch.Backtrack@ Used on single-token analyses; tell hfst-tokenise/pmatch to backtrack by reanalysing the substrings before and after this poin in the form (to find combinations of shorter analyses that would otherwise be missed)
@D.ErrOrth.ON@ asdf
@C.ErrOrth@ asdf
@P.ErrOrth.ON@ asdf

Derivation tags and derivation position tags in a derivation row

Derivations in the same position are mutually exclusive (can not be combined), whereas tags in different positions can be combined, so that position 1 derivations must precede position 2 derivations, and so on.

Other, non-positional derivations

All non-positional derivations should be preceded by the following tag, to make it possible to target regular expressions in all derivations in a language-independent way: just specify [+Der](+Der1 .. +Der5) and you are set.

Derivation tag POS switch Explanation
+Der/PassS VV short passive only
+Der/A NA comparation of N’s

Tags for originating language

The following tags are used to guide conversion to IPA: loan words and foreign names are usually pronounced (approximately) as in the originating (majority) language. Instead of trying to identify the correct pronunciation based on phonotactics (orthotactics actually), we tag all words that can’t be correctly transcribed using the SMA transcriber with source language codes. Once tagged, it is possible to apply different IPA conversions to each of them. The principle of tagging is that we only tag to the extent needed, and following a priority:

  1. any untagged word is pronounced with native orthographic conventions
  2. NNO and NOB have identical pronunciation, NNO is only used if different in spelling from NOB
  3. SWE has mostly the same pronunciation as NOB, and is only used if different in spelling from NOB
  4. Occasionally even SMA (the default) may be tagged, to block other languages from being specified, mainly during semi-automatic language tagging sessions All in all, we want to get as much correctly transcribed to IPA with as little work as possible. On the other hand, if more words are tagged than strictly needed, this should pose no problem as long as the IPA conversion is correct - at least some words will get the same pronunciation whether read as SMA or NOB/NNO/SWE.

Symbol used before # and - in dynamic compounds, and only there. Used to block optional conversion of word boundaries to spaces for error detection in grammar checkers. That is, dynamic compounds are not allowed to be written appart for error detection, only lexicalised ones. This is done to reduce the amound of ambiguity in the raw analyses to an amount we can cope with.

Flag diacritics

We have manually optimised the structure of our lexicon using the following flag diacritics to restrict morhpological combinatorics - only allow compounds with verbs if the verb is further derived into a noun again:

Flag Explanation
@P.NeedNoun.ON@ (Dis)allow compounds with verbs unless nominalised
@D.NeedNoun.ON@ (Dis)allow compounds with verbs unless nominalised
@C.NeedNoun@ (Dis)allow compounds with verbs unless nominalised
@R.ErrOrth.ON@  

For languages that allow compounding, the following flag diacritics are needed to control position-based compounding restrictions for nominals. Their use is handled automatically if combined with +CmpN/xxx tags. If not used, they will do no harm.

Flag Explanation
@P.CmpFrst.FALSE@ Require that words tagged as such only appear first
@D.CmpPref.TRUE@ Block such words from entering ENDLEX
@P.CmpPref.FALSE@ Block these words from making further compounds
@D.CmpLast.TRUE@ Block such words from entering R
@D.CmpNone.TRUE@ Combines with the next tag to prohibit compounding
@U.CmpNone.FALSE@ Combines with the prev tag to prohibit compounding
@U.CmpNone.TRUE@ Combines with the two previous ones to block compounding
@P.CmpOnly.TRUE@ Sets a flag to indicate that the word has passed R
@D.CmpOnly.FALSE@ Disallow words coming directly from root.
@U.CmpHyph.FALSE@ Flag to control hyphenated compounds like proper nouns
@U.CmpHyph.TRUE@ Flag to control hyphenated compounds like proper nouns
@C.CmpHyph@ Flag to control hyphenated compounds like proper nouns

Use the following flag diacritics to control downcasing of derived proper nouns (e.g. Finnish Pariisi -> pariisilainen). See e.g. North Sámi for how to use these flags. There exists a ready-made regex that will do the actual down-casing given the proper use of these flags.

Flag Explanation
@U.Cap.Obl@ Allowing downcasing of derived names: deatnulasj.
@U.Cap.Opt@ Allowing downcasing of derived names: deatnulasj.

The following flag diacritics are used by the grammar checker.

Flag Explanation
@R.SpellRlx.ON@ Flag used to tag spell-relax-analysed strings (and only those).
@D.SpellRlx.ON@ Flag used to tag spell-relax-analysed strings (and only those).
@C.SpellRlx@ Flag used to tag spell-relax-analysed strings (and only those).
@P.Pmatch.Loc@ Used on multi-token analyses; tell hfst-tokenise/pmatch where in the form/analysis the token should be split.
@P.Pmatch.Backtrack@ Used on single-token analyses; tell hfst-tokenise/pmatch to backtrack by reanalysing the substrings before and after this point in the form (to find combinations of shorter analyses that would otherwise be missed)

Lexicon Root

This is the beginning of everything. The Root lexicon is reserved in the LexC language, and must be the first lexicon defined.

Here is the list of top-level lexica in the South Sámi analyser:

Lexicon ENDLEX

And this is the ENDLEX of everything:

@D.CmpOnly.FALSE@@D.CmpPref.TRUE@@D.NeedNoun.ON@ ENDLEX2 ;

The @D.CmpOnly.FALSE@ flag diacritic is ued to disallow words tagged with +CmpNP/Only to end here. The @D.NeedNoun.ON@ flag diacritic is used to block illegal compounds.
