In this thesis, we present an event orderer application that works on Turkish texts. Events are words denoting an occurrence or happenings in natural language texts. By using the features of the events in a sentence or by the helps of temporal expressions in the sentence, anchoring an event on a timeline or ordering events between other events are called event ordering. The application presented in this thesis, is one of the earliest study in this domain with Turkish and it realizes all needed sub modules for event ordering. It realizes event recognition in Turkish texts and event feature detection in Turkish texts. In addition to this, the application is realizing temporal expression recognition and temporal signal recognition tasks.

Apoiando-se em uma perspectiva enunciativa, este estudo busca investigar o funcionamento do sistema verbal das Línguas Francesa e Portuguesa do Brasil, com o objetivo de verificar a expressão do tempo passado, em produções textuais de um grupo de alunos de Letras da USP cursando o terceiro semestre de Língua Francesa. Vinte e um alunos selecionados produziram quatro textos cada um durante o semestre, totalizando oitenta e quatro textos que foram analisados. Com essa finalidade, iniciamos nossa pesquisa, apoiados pelos estudos da temporalidade, da expressão de tempo em narrativas midiáticas e da enunciação. Com os trabalhos de Imbs (1960), Benveniste (1966, 1974), Bronckart (1999), Charaudeau (1992) e Fiorin (2002), observamos que, embora o sistema verbal de ambas as línguas seja semelhante, há, entretanto, algumas diferenças marcantes em relação aos verbos que denotam pretérito. Os estudos enunciativos mostram-nos que o sistema temporal é bastante complexo, mas é coerente. Partimos do pressuposto de que se essa coerência é exposta e trabalhada com os aprendizes de francês, estes terão menos dificuldades na expressão do tempo em Língua Francesa. A expressão do tempo foi apresentada aos alunos a partir de uma abordagem enunciativa, e o gênero textual escolhido pelo docente para o ensino/aprendizagem da temporalidade foi o faits divers, narrativa midiática típica francesa. As narrativas, em geral, não seguem a sucessão natural dos acontecimentos, mas, de qualquer forma, são relatadas a partir do momento de enunciação (ME), instalado no texto pelo enunciador. A partir do ME, são marcados os momentos de referência presente, passado, futuro; e em relação a cada um deles, os acontecimentos podem ser concomitantes, anteriores ou posteriores. As análises efetuadas mostraram que o ensino/aprendizagem, a partir dos estudos enunciativos, faz com que os alunos percebam a não linearidade temporal, consigam marcá-la linguisticamente com tempos verbais e com expressões temporais e produzam narrativas temporalmente coerentes. / Based on an enunciative perspective, this study aims to investigate the operation of the verbal system of both languages French and Brazilian Portuguese, with the objective of verifying the expression of the past tense, in textual productions of a group from USP Language students of the third semester of French Language. Twenty-one selected students produced four texts each, during the semester, in a total of eighty four texts which were analyzed. With this purpose, we began our research, supported by the studies of temporality, time expression in mediatic and enunciative narratives. The works by Imbs (1960), Benveniste (1966, 1974), Bronckart (1999), Charaudeau (1992) and Fiorin (2002) permitted to observe that, although the verbal system of both languages is similar, there are, however, some outstanding differences in relation to the verbs that denote preterit. Enunciative studies show us that the temporal system is very complex but coherent. We start from the assumption that if this coherence is exposed and worked with French learners, they will have fewer difficulties concerning time expression in French Language. Time expression was introduced to the students starting from an enunciative approach, and the textual gender chosen by the teacher for the teaching/learning process of the temporality was the faits divers, a typical mediatic French narrative. The narratives, in general, do not follow the natural succession of events, but are, somehow, reported after the enunciation moment (EM), established in the text by the enunciator. After the EM, the reference moments of present, past, future, are marked; and in relation to each of them, the events can be simultaneous, previous or subsequent. The analysis performed showed that the teaching / learning process, starting from the enunciative studies, allows students to notice the non-temporal linearity, enabling them to mark it linguistically with verbal tenses and temporal expressions and to produce temporally coherent narratives.

Temporal constructions in Afrikaans are ambiguous with respect to aspectual meaning. The past tense construction with het ge-, for instance, can be interpreted as progressive, perfective or anterior. In the same vein, the unmarked present tense construction can be interpreted as a construction with a progressive or a perfective meaning. This aspectual ambiguity of the Afrikaans verbal system has a significant effect on the way in which Afrikaans grammar is described or understood. The observation by native speakers, linguists, literary specialists and writers that the temporal constructions in Afrikaans are vague or ambiguous with regard to aspectual meaning has led to certain views about the expression of tense in the language. In Afrikaans literature, for example, there is a tradition to write prose primarily in the present tense, because of the perception that the past tense is not adequate to convey particular semantic nuances. Furthermore, certain speakers of Afrikaans and linguists believe that Afrikaans grammar has been simplified and just does not have aspect. However, Afrikaans possesses alternative strategies to specify aspectual meaning. The five prototypical ways of expressing aspectual meaning in Afrikaans are i) lexical constructions (such as adverbs and conjunctions); ii) constructions with affixes, iii) reduplication constructions; iv) passive constructions; and v) periphrastic constructions. Aspectual meaning in Afrikaans is an almost entirely unexplored research field. In my opinion, the literature on the expressions of aspectual meaning in Afrikaans contains two shortcomings. First, Afrikaans aspect needs to be described theoretically. Second, more research is needed concerning the specific ways in which aspectual meaning is expressed in Afrikaans. The scope of this entire research field is too large for a single study. For that reason, the present study aims to reveal the way in which periphrastic constructions are used to convey progressive meaning. As far as temporal meaning is concerned, it is possible to make a distinction between tempus meaning, which stands for deictic temporal meanings (i.e. past, present and future tense), and aspectual meaning, which stands for non-deictic temporal meanings such as duration, point of view and the internal structure of the situation. One can also distinguish between lexical and grammatical aspect. Lexical aspect has to do with the conceptual properties of a situation or, in other words, with the question whether it is static or dynamic, telic or atelic and durative. There are five situation types: states, activities, achievements, accomplishments and semelfactives. Grammatical aspect concerns the point of view from which the situation is perceived. One can make a distinction between perfective and imperfective grammatical aspect. The latter can be subdivided into imperfectives conveying habitual meaning and imperfectives conveying progressive meaning. Grammaticalisation theory is useful and a relevant tool to provide answers to the afore-mentioned research questions. First, it offers insight into the manner in which the ambiguous tempus constructions of Afrikaans came into being. Second, it can be used to show how the alternative aspectual constructions have developed and how they are currently employed in the language. For the purpose of this study, grammaticalisation is regarded as language change in which a construction loses its lexical meaning and comes to express grammatical meaning. Grammatical constructions can be used in more contexts than their lexical counterparts, as grammaticalised uses have been generalized contextually. Grammatical constructions lose the morphosyntactic properties typical of their lexical counterparts and assume grammatical properties. Grammaticalisation is a typological phenomenon and the lexical origin of a grammatical construction is often the same in different languages. Grammaticalizing constructions exhibit an increase in frequency. Afrikaans and Dutch are closely related languages and possess cognate periphrastic progressive constructions, viz. i) the aan het- / aan die- ii) VPOS te / VPOS en-; en iii) bezig- / besig- progressive constructions. To examine the use of periphrastic progressive constructions in Afrikaans from a grammaticalisation perspective, I compare the results of a study of these constructions in an Afrikaans corpus to those of previous studies of the periphrastic progressive constructions in Dutch. The respective constructions are compared on the basis of four criteria, viz. i) frequency; ii) verb collocations; iii) transitivity; and iv) combinatorial possibilities with other aspectual periphrastic constructions. The lexical origins of the various constructions are also considered. The comparison of the constructions on the basis of the afore-mentioned criteria makes it possible to demonstrate how the periphrastic progressive constructions in Afrikaans came into being and how they have developed into grammatical constructions conveying aspectual meaning and in which way the different Afrikaans periphrastic constructions express progressive meaning. / PhD (Afrikaans and Dutch), North-West University, Potchefstroom Campus, 2012
