Write rules in Portuguese

Supported sentence structures

Both Portuguese (European) and Portuguese (Brazilian) parsers support Subject – Verb – Object sentences.

Supported verb forms

Portuguese verbs conjugate in a significant number of tenses and several moods. The indicative mood is used for factual statements; the subjunctive mood is used for uncertain sentences, as well as some "if ... then ..." sentences.

Although gender (masculine and feminine) is present in Portuguese, the second and third person forms in most tenses are the same for both genders. Additionally, the polite second person form uses the third person verb conjugation.

The verbs list in Oracle Policy Modeling contains entries for the following tense and mood combinations:

Tense	Mood	Verb forms
Present	Indicative	Singular 3rd person, plural 3rd person
Imperfect	Indicative	Singular 3rd person, plural 3rd person
Future	Indicative	Singular 3rd person, plural 3rd person
Preterite	Indicative	Singular 3rd person, plural 3rd person
Present	Subjunctive	Singular 3rd person, plural 3rd person
Imperfect	Subjunctive	Singular 3rd person, plural 3rd person
Future	Subjunctive	Singular 3rd person, plural 3rd person
Gerund	N/A	One form
Past Participle	N/A	Masculine singular, masculine plural, feminine singular, feminine plural

The parser supports both simple and compound verb constructions. For example:

a simple verb sentence is a moça estuda bem (the lady studies well)
a compound verb sentence is os salários foram pagos pelas empresas públicas (the salaries were paid by the public companies)

Limitations

Substitutions

In order for the substitution to work correctly, every variable and entity should either be preceded by the article, or by a contracted preposition + article.

The following prepositions are supported for substitution:

de – the contracted forms do and da are supported.

For example, a caneca do candidato (the mug of the candidate) becomes a caneca do Leo when Leo is substituted for o candidato.

por – the contracted forms pelo and pela are supported.

For example, pelo candidato (by the candidate) becomes por Leo when Leo is substituted for o candidato.

a – the contracted forms ao and à are supported.

For example, ao agente fiscal (to the fiscal agent) becomes à Lia when Lia is substituted for o agente fiscal and the gender of the variable o agente fiscal is set to Feminine at runtime.

para – the form para is supported.

For example, para a senhora (for the lady) becomes para Lia when Lia is substituted for a senhora.

The following guidelines must be followed for substitution to work correctly:

Each variable attribute should include the article. For example, use o candidato instead of candidato.
Each variable used in a nominative sentence should include the article. For example, use o candidato tem a caneca instead of candidato tem a caneca.
Each variable used in a sentence with a preposition should include the appropriate contracted preposition + article. For example, use os pontos foram atribuídos ao agente fiscal instead of os pontos foram atribuídos o agente fiscal.
There must be exactly one space between the article/preposition and the variable name. For example, use os pontos foram atribuídos ao agente fiscal instead of os pontos foram atribuídos ao agente fiscal.

In order for 2nd person substitution of possessives to work correctly, the object possessed may consist of one word only. For example, a caneca do candidato can be correctly transformed into a sua caneca. However, a caneca azul do candidato (the candidate's blue mug) cannot be correctly transformed into a 2nd person sentence. It can, however, be transformed into a 3rd person sentence a caneca azul do %varid?% where "varid" is the public name for the variable o candidato.
