The recognition of named entities in Spanish medieval texts presents great complexity, involving specific challenges: First, the complex morphosyntactic characteristics in proper‐noun use in medieval ...texts. Second, the lack of strict orthographic standards. Finally, diachronic and geographical variations in Spanish from the 12th to 15th century. In this period, named entities usually appear as complex text structure. For example, it was frequent to add nicknames and information about the persons role in society and geographic origin. To tackle this complexity, named entity recognition and classification system has been implemented. The system uses contextual cues based on semantics to detect entities and assign a type. Given the occurrence of entities with attached attributes, entity contexts are also parsed to determine entity‐type‐specific dependencies for these attributes. Moreover, it uses a variant generator to handle the diachronic evolution of Spanish medieval terms from a phonetic and morphosyntactic viewpoint. The tool iteratively enriches its proper lexica, dictionaries, and gazetteers. The system was evaluated on a corpus of over 3,000 manually annotated entities of different types and periods, obtaining F1 scores between 0.74 and 0.87. Attribute annotation was evaluated for a person and role name attributes with an overall F1 of 0.75.

The incorporation of the humanities into digital transformation processes resulted in the emergence of a new research field called digital humanities. This new field has its origin in the beginning ...of the second half of the twentieth century. From the research point of view, through the analysis of the scientific production of the main academic databases, we provide here an overview of the international panorama of digital humanities, looking at the main countries, institutions, areas of knowledge and leading topics in this discipline.

This article provides a comprehensive and up-to-date survey of models and vocabularies for creating linguistic linked data (LLD) focusing on the latest developments in the area and both building upon ...and complementing previous works covering similar territory. The article begins with an overview of some recent trends which have had a significant impact on linked data models and vocabularies. Next, we give a general overview of existing vocabularies and models for different categories of LLD resource. After which we look at some of the latest developments in community standards and initiatives including descriptions of recent work on the OntoLex-Lemon model, a survey of recent initiatives in linguistic annotation and LLD, and a discussion of the LLD metadata vocabularies META-SHARE and lime. In the next part of the paper, we focus on the influence of projects on LLD models and vocabularies, starting with a general survey of relevant projects, before dedicating individual sections to a number of recent projects and their impact on LLD vocabularies and models. Finally, in the conclusion, we look ahead at some future challenges for LLD models and vocabularies. The appendix to the paper consists of a brief introduction to the OntoLex-Lemon model.
The automatic metric analysis (commonly referred to as scansion ) of Spanish poetry is not a trivial problem since it combines the nuances of the language, the different poetic traditions related to ...melodic patterns, and the personal stylistic preferences and intentions of the author. In this paper, we explore two alternative algorithmic approaches tailored to different applications scenarios. The first approach, Rantanplan, is a rule-based method that consists of four Natural Language Processing modules that work together to perform scansion and other related analysis: Part of Speech tagging, syllabification, stress assignment, and metrical adjustment. The second approach, Jumper, explores the possibility of performing scansion without syllabification, with a twofold purpose: to minimize the errors propagated in different parts of the linguistic processing pipeline (including the syllabification step), and to improve the efficiency of the process. Both systems outperform the state of the art and provide either a more informative solution (suitable, for instance, for teaching purposes) or a more efficient processing (when a correct scansion is all the linguistic knowledge required, as in scholar philological studies). The combined use of both systems turns out to provide a practical tool to clean-up manual annotation errors in corpora.
As in other research fields, the development of learning analytics is influenced by the networks of researchers that contribute to it. This paper describes one of such networks: the Spanish Network ...of Learning Analytics (SNOLA). The paper presents the research lines of the members of SNOLA, as well as the main challenges that learning analytics has to address in the next few years as perceived by these researchers. This analysis is based on SNOLA's archival data and on a survey carried out to the current members of the network. Although this approach does not cover all the activity related to learning analytics in Spain, the results provide a representative overview of the current state of research related to learning analytics in this context. The paper describes these trends and the main challenges, among which we can point out the need to adopt an ethical commitment with data, to develop systems that respond to the requirements of the end users, and to reach a wider institutional impact.
En este comentario de la traducción catalana de 1987 del clásico de 1929 de Karl Mannheim, Ideología y Utopía, se argumenta que el contexto sociopolítico de los 70 ha influenciado profundamente las ...interpretaciones de la obra. Se pasa revista a los debates surgidos tras su publicación, concluyéndose que fue la excesiva expectación generada la principal causa de la incompresión y críticas posteriores. Se discuten las traducciones de algunos de sus conceptos cruciales, poniéndose de manifiesto el hecho de que muchas de éstas son el claro resultado de una antipatía ideológica que ha llevado a interpretaciones caprichosas.
The aim of this work is to provide a navigation paradigm that could be used to control a wheelchair through a brain–computer interface (BCI). In such a case, it is desirable to control the system ...without a graphical interface so that it will be useful for people without gaze control. Thus, an audio-cued paradigm with several navigation commands is proposed. In order to reduce the probability of misclassification, the BCI operates with only two mental tasks: relaxed state versus imagination of right hand movements; the use of motor imagery for navigation control is not yet extended among the auditory BCIs. Two experiments are described: in the first one, users practice the switch from a graphical to an audio-cued interface with a virtual wheelchair; in the second one, they change from virtual to real environments. The obtained results support the use of the proposed interface to control a real wheelchair without the need of a screen to provide visual stimuli or feedback.
The WWW nowadays enables faculty to develop new Internet-based applications that can be used to enhance classroom instruction. There is a clear evolution towards the implementation of new ...service-oriented learning/teaching systems, which can be considered as the latest generation of Internet-based platforms. This work first describes a service-oriented system in order to follow the students' progress and automatically assess their practical activities, not theoretical knowledge. The service oriented paradigm allows us to implement a more advanced system for the self-evaluation and continuous assessment of the students' progress in the field of Information Technology, where activities measure practical daily-work skills. Second, the Technology Acceptance Model (TAM) is used to analyze the acceptance of our proposal. In the results obtained, the participants found the system significantly easier to use, and it proved useful for their purposes. It is also concluded that participants (students and faculty) feel confident with the system.

Medieval documents are a rich source of historical data. Performing named-entity recognition (NER) on this genre of texts can provide us with valuable historical evidence. However, traditional NER ...categories and schemes are usually designed with modern documents in mind (i.e. journalistic text) and the general-domain NER annotation schemes fail to capture the nature of medieval entities. In this paper we explore the challenges of performing named-entity annotation on a corpus of Spanish medieval documents: we discuss the mismatches that arise when applying traditional NER categories to a corpus of Spanish medieval documents and we propose a novel humanist-friendly TEI-compliant annotation scheme and guidelines intended to capture the particular nature of medieval entities.
