Expressões multipalavras no discurso de fóruns sobre saúde mental: desenvolvimento de um corpus em inglês e português brasileiro
Resumo
Expressões multipalavras (multiword expressions, MWEs), isto é, sequências de palavras que apresentam algum grau de idiossincrasia, são centrais tanto para os estudos linguísticos quanto para o Processamento de Linguagem Natural (PLN). Este artigo apresenta a criação de um novo corpus de MWEs em postagens em inglês e português brasileiro de comunidades do Reddit dedicadas à saúde mental — um domínio ainda sub-representado nos recursos existentes de MWEs, predominantemente baseados em textos jornalísticos. O corpus foi compilado manualmente, anotado automaticamente com informações morfossintáticas e sintáticas por meio do parser UDPipe, revisado no Arborator Grew e anotado manualmente na plataforma FLAT, seguindo as diretrizes do PARSEME. A análise combina a distribuição de frequência por categoria de MWE e uma investigação contrastiva interlinguística. Os resultados evidenciam especificidades das MWEs nesse domínio e construções que funcionam como recursos convencionalizados para expressar sentimentos, avaliações e estados subjetivos no discurso sobre saúde mental nas redes sociais.Referências
