Tense is a small element to a sentence, however, error tense can raise odd grammars and result in misunderstanding. Recently, tense has drawn attention in many natural language processing applications. However, most of current Statistical Machine Translation (SMT) systems mainly depend on translation model and language model. They never consider and make full use of tense information. In this p...

There have been heated debates on whether tense markers in Korean are inflectional affixes or syntactic words. One of the strongest pieces of evidence for the latter position comes from tense-related phenomena in -ko constructions. These constructions are usually assumed to consist of two coordinate clauses. In this paper, we will see that the tense phenomena can be accounted for naturally by c...

Many languages allow for ”fake” uses of their past tense marker: the marker can occur in certain contexts without conveying temporal pastness. Instead it appears to bear a modal meaning. Iatridou [2000] has coined this phenomenon Fake Tense. Fake Tense is particularly common to conditional construction. This paper proposes to explain Fake Tense in English conditional sentences as a certain kind...

This study examines F0 influence on perception of Korean initial lax, aspirated, and tense consonants by Japanese learners of the Korean language. Stimuli consisted of monosyllabic sounds (/ta, tsa, ta, tsa/) with interchanged F0s, including lax and aspirated consonants. Results from recognition testing of the stimuli found that both beginning and advanced learners paid less attention to stimul...

Languages that are classified as non-Sequence-of-Tense come in more than one variety (e.g., Arregui & Kusumoto 1998): some of these languages allow a past tense in beforeclauses while others do not. We propose that some languages have quantificational (existential) tenses, while others have pronominal (referential/bound) tenses. The past tense in before-clauses is ill-formed in a language that ...

In a majority of languages, the time of an event is expressed by marking tense on the verb. There is substantial evidence that the production of verb tense in sentences is more severely impaired than other functional categories in persons with agrammatic aphasia. The underlying source of this verb tense impairment is less clear, particularly in terms of the relative contribution of conceptual-s...

Grammaticalized expressions of time are found across languages. In particular, temporal information can be conveyed through tense morphology, which indicates an event’s location of time based on a referent event (Comrie, 1985) and through aspect morphology, which indicates “ways of viewing the internal temporal constituency of a situation” (e.g., is an event ongoing or completed; Comrie, 1976, ...

In 1982, L. Iturrioz introduced symmetrical Heyting algebras of order n (or SHnalgebras). In this paper, we define and study tense SHn-algebras namely, SHnalgebras endowed with two tense operators. These algebras constitute a generalization of tense Łukasiewicz-Moisil algebras. Our main interest is the duality theory for tense SHn-algebras. In order to do this, we requiere Esakia’s duality for ...
