Multilingualism presents both a challenge and an opportunity for Natural Language Processing, with code-switching representing a particularly interesting problem for computational models trained on monolingual datasets. In this paper, we explore how code-switched data affects the task of Machine Translation, a task which only recently has started…

According to the nonce borrowing hypothesis (NBH), "[n]once borrowings pattern exactly like their native counterparts in the (unmixed) recipient language" (Poplack & Meechan, 1998a, p. 137). Nonce borrowings (Sankoff, Poplack & Vanniarajan, 1990, p. 74) are "lone other-language items" which differ from established borrowings in terms of frequency…

The authors of "Phrase-final prepositions in Quebec French: An empirical study of contact, code-switching and resistance to convergence", Poplack, Zentz & Dion (2011, this issue), henceforth cited as PZD, make a strong case for showing that, in spite of surface similarities, preposition stranding in Canadian French relative clauses…

Previous work on intrasentential codeswitching has noted that switches between determiners and their noun complements are frequent in both Spanish-English and Welsh-English data. Two major recent theories of codeswitching, the Matrix Language Frame model and a Minimalist Program approach, make potentially competing predictions regarding the source…

Discusses the code-switching in English and Spanish of adjectives or nouns inside a noun phrase containing both. Proposes that the device that prevents switched prenominal Spanish adjectives is the same one that prevents the same classes of adjectives from normally appearing in prenominal position in Spanish.

Investigates the construction of the grammatical frame in code switching in terms of the roles played by the two languages in contact, referred to as the Matrix Language (ML) and the Embedded Language (EL). Data is presented from German-English code switching on gender assignment and article in noun phrases. (Author/VWL)

This paper aims to contribute to elucidating the notion of congruence in code-switching with particular reference to Welsh-English data. It has been suggested that a sufficient degree of congruence or equivalence between the constituents of one language and another is necessary in order for code-switching to take place. We shall distinguish…

Presents an analysis of code switching that relies on general principles of phrase structure and rejects constraints specific to code switching. This model is shown to account for intersentential switches between typologically different languages such as Farsi and English, including within word switches and switches between modifiers and nouns.…
