    Digital Humanities researchers often make use of software that helps them in the task of finding non-trivial relationships among characters in historical text. Usually, the source texts that contain such information come from OCR acquired volumes, carrying high amounts of errors within them. This work explains the development of a web platform for the task of OCR post-processing and ground-truth generation. This platform employs machine learning to predict the correct texts accurately from OCR noisy strings. The method used for this task involves transformers for character-based denoising language models. An active learning workflow is proposed, as the users can feed their corrections to the platform, generating new annotated data for re-training the underlying machine learning correction models.

    Large amounts of ancient documents have become available in the last years, regarding Argentinian history. This fact turns possible to find interesting and useful aggregated information. This work proposes the application of Natural Language Processing, Text Mining and Visualization tools over Argentinian ancient document repositories. Conceptual maps and entity networks make up the first target of this preliminary paper. The first step is the normalization of OCR acquired books of General G¨uemes. Exploratory analyses reveal the presence of manifold spelling errors, due to the OCR acquisition process of the volumes. We propose smart automatic ways for overcoming this issue in the process of normalization. Besides, a first topic landscape of a subset of volumes is obtained and analysed, via Topic Modelling tools.

    In recent years there has been a significant increase in the number and impact of damage caused by natural disasters, as well as the frequency, extent and duration of extreme weather events. In that sense, the 2030 Agenda for Sustainable Development proposes 17 objectives through which countries will intensify their efforts to combat climate change. Among the goals is proposed to increase efforts to protect and safeguard the world's cultural and natural heritage. This article presents one of the case studies of an ongoing doctoral research that assesses the level of conservation and sustainability in cultural buildings. The case is the Museum of Contemporary Art Beato Angelico, which is located in La Plata, Argentina. The objective is to carry out environmental monitoring of the museum for a period of twelve months. This consists in the recording and analysis of environmental conditions through the continuous measurement of temperature and relative humidity. This article presents the results of the winter measurement of 2015. The spatial characteristics of the rooms and their relative location within the building are considered, it is concluded by determining the behavior of the different exhibition spaces.

    This paper presents a series of semi-supervised learning algorithms which were designed to classify words or expressions with temporal meanings. The algorithms use a set of pre-tagged temporal expressions and a set of semantic classes which were defined within a research project on the lexical coding of temporal meaning in Spanish. The algorithms in this article are mostly based on word embeddings, but they also make use of other methods. The results obtained strongly depend on the temporal classes considered, but, for some classes, results have reached 90% precision or above.

    El siguiente trabajo se constituye como una aproximación al concepto de representación desde la teoría psicoanalítica freudiana. Para ello, se harán consideraciones epistemológicas acerca de los orígenes filosóficos del término, un rastreo histórico de los diferentes modelos de aparato psíquico y un análisis metapsicológico para clasificar las distintas definiciones del concepto de representación a partir de los modelos que intentan dar explicación al origen del aparato psíquico. Cada uno de estos sistemas supone diversos tipos de inscripciones que se rigen por distintas legalidades: signo de percepción, representación-cosa y representación-palabra. Se privilegiará el modelo de la “Carta 52”, donde expone por primera vez su hipótesis acerca de la composición del aparato psíquico como un sistema de inscripciones en términos de signos. El objetivo será, por lo tanto, caracterizar estas tres formas de representación de “la cosa del mundo” tomando en cuenta sus coincidencias, diferencias y relaciones. Fundamentalmente, qué suponen en tanto inscripciones y retranscripciones en función de los intercambios al interior del psiquismo y sus relaciones con el mundo. Se fundamentará una lectura del concepto de representación enfatizando su carácter de producto resultante de la actividad simbolizante del sujeto. The following work is constituted as an approximation to the concept of representation from the Freudian psychoanalytic theory. For this, epistemological considerations will be made about the philosophical origins of the term, a historical tracing of the different models of psychic apparatus and a metapsychological analysis to classify the different definitions of the concept of representation from the models that try to explain the origin of the Psychic apparatus Each of these systems involves different types of inscriptions that are governed by different legalities: sign of perception, representationthing and representation-word. The model of “Letter 52” will be privileged, where it exposes for the first time its hypothesis about the composition of the psychic apparatus as a system of inscriptions in terms of signs. The objective will be, therefore, to characterize these three forms of representation of “the thing of the world” taking into account their coincidences, differences and relations. Fundamentally, what do they imply in both inscriptions and retranscriptions in terms of exchanges within the psyche and its relations with the world. A reading of the concept of representation will be based emphasizing its product character resulting from the symbolizing activity of the subject. Facultad de Psicología
