Kohesio anaforikoa. Adinaren eta testu generoaren araberako azterketa

[EN] The main focus of this paper is the cohesion of the theme. First of all, placing anaphoric cohesion within the theoretical framework developed by Bronckart (1985, 1996), we need to distinguish between cohesion, connection and coherence; and furthermore, within the field of cohesion we need to distinguish between verbal cohesion and cohesion as regards nouns. Similarly, the paper also defines discourse as the linguistic realisation of the text, and talks about different types of discourse and textual genres. Next, the paper focuses on the different approaches to cohesion. Since anaphoric cohesion is the cornerstone of the study, some limits of this concept are defined and its main indicators specified. Studies carried out from four different perspectives are taken into consideration: those that focus on understanding pronominal anaphora; those that seek to analyse the discursive side of language acquisition; those that look at anaphora and written texts; and those that concentrate on the didactic side of anaphora. From the model offered by Bronckart’s theory and the aforementioned studies, the following hypothesis is extracted: in Basque, language development is something which takes a long time, and textual genre plays an important role in defining and determining this development.

Query-by-Example Spoken Term Detection ALBAYZIN 2012 evaluation: overview, systems, results, and discussion

Query-by-Example Spoken Term Detection (QbE STD) aims at retrieving data from a speech data repository given an acoustic query containing the term of interest as input. Nowadays, it has been receiving much interest due to the high volume of information stored in audio or audiovisual format. QbE STD differs from automatic speech recognition (ASR) and keyword spotting (KWS)/spoken term detection (STD) since ASR is interested in all the terms/words that appear in the speech signal and KWS/STD relies on a textual transcription of the search term to retrieve the speech data. This paper presents the systems submitted to the ALBAYZIN 2012 QbE STD evaluation held as a part of ALBAYZIN 2012 evaluation campaign within the context of the IberSPEECH 2012 Conference(a). The evaluation consists of retrieving the speech files that contain the input queries, indicating their start and end timestamps within the appropriate speech file. Evaluation is conducted on a Spanish spontaneous speech database containing a set of talks from MAVIR workshops(b), which amount at about 7 h of speech in total. We present the database metric systems submitted along with all results and some discussion. Four different research groups took part in the evaluation. Evaluation results show the difficulty of this task and the limited performance indicates there is still a lot of room for improvement. The best result is achieved by a dynamic time warping-based search over Gaussian posteriorgrams/posterior phoneme probabilities. This paper also compares the systems aiming at establishing the best technique dealing with that difficult task and looking for defining promising directions for this relatively novel task.

Huerto urbano comunitario

El proyecto que se expone a continuación consiste en la creación de un Huerto Urbano Comunitario. Los criterios en los que se sustenta son; la soberanía alimentaria, el desarrollo comunitario y la sostenibilidad. Se pretende con él que los participantes adquieran formación y conciencia crítica sobre los modos de producción y consumo agrícola. Para ello se estimulará la implicación mediante dinámicas de grupo, charlas, proyecciones, excursiones, debates, etc. Sin olvidarnos en ningún momento del trabajo manual y todas las acciones necesarias para la creación del propio huerto.
