abstract = {In cultural heritage, various methods have addressed three-dimensional (3D) digitization and reconstruction using two-dimensional (2D) images, including shape from structured light, shape from stereo, and structure from motion. A common challenge is the recognition of the distance of objects in a scene from the viewpoint, usually called depth. Recognizing depth in 2D photographs remains a challenge in computer vision. Deep Learning techniques have improved this area, particularly in what is called monocular depth estimation. This work investigates the applicability of state-of-the-art monocular depth estimation methods as a preliminary step toward complete and automated 3D reconstruction of cultural heritage artifacts. As image-based 3D reconstruction is extremely time-consuming and expertise-demanding, monocular depth estimation methods could provide significant advantages in speeding up the overall process. Our preliminary experiments yield promising results, with a mean accuracy of 88.15%, a mean RMSE error of 37.35, and a mean PSNR of 27.37 dB across these methods.},

The corpus of Pomak compiled by ``Philotis'' contains about 140,000 words selected from a variety of text types including web articles, pieces of news, novels, poems, proverbs, traditional songs, folk tales and language lessons. The resources that resulted from this effort are openly available to Natural Language Processing practitioners and could be helpful for an advanced quantitative and qualitative analysis of the use and structure of Pomak.},

abstract = {Developing language treebanks is a challenging and time-consuming process, especially for under-resourced languages with limited data. This study proposes the use of active learning approaches to automate aspects of this process, aiming to reduce both annotation duration and cost. We propose practical active annotation schemes in which experts strategically select sentences for the training set, initiating a circular process involving annotation prediction, expert correction, and model retraining. To validate the feasibility of these schemes, we applied them to 300 annotated sentences from the newly created Pomak corpus (an under-resourced language), recently published in Universal Dependencies treebanks, as the result of our efforts. Through experiments involving a simple weighted summation of annotation errors, we identified an optimal strategy. This strategy resulted in a 69% reduction in total annotation duration and an associated 81% decrease in total corresponding cost compared to a typical manual annotation, demonstrating the effectiveness of this approach.},

With VR expanding into education, healthcare, and social sciences, accurate emotion recognition is essential. This paper addresses the challenge of limited data by proposing a modified MixUp algorithm for VR emotion recognition. Our technique, which selectively combines data points within the same class, improves model generalization and accuracy. Testing on the VREED dataset demonstrates significant enhancements. This study reviews VR and emotion recognition technologies, details the class-intrinsic MixUp method, and discusses implications and future directions for humanities research using VR.},

abstract = {A major challenge faced by visually impaired visitors in museums is the limited availability of haptic experiences, due to the ``do not touch'' principle, inevitably imposed in such places. This limitation discourages them from truly exploring exhibits, as their primary mode of experiencing the world relies on touch and hearing. Although many museums worldwide strive to eliminate this barrier, museums in Greece seem to be slow in meeting relevant standards, thus resulting in places with limited accessibility. However, Greek museums increasingly recognize the importance of providing various tactile experiences to bridge this gap. Research projects and small-scale technological applications are being implemented with encouraging results, but financial constraints, lack of awareness and specialized staff training are some of the challenges that limit the more extended and permanent incorporation of such tools and systems.},

abstract = {This study investigates the lexicographic treatment of the term humor across a range of historical and contemporary dictionaries of Modern Greek, focusing on differences in definition, examples of use, as well as other elements of the dictionaries’ microstructure. The analysis spans general-purpose dictionaries, specialized linguistic works, and encyclopedic references, covering various linguistic traditions and time periods. By comparing dictionary entries, this study explores how humor has been conceptualized in relation to its psychological and cultural dimensions, as well as how these interpretations have evolved over time. Additionally, the study evaluates the extent to which dictionary definitions reflect broader societal attitudes toward humor. Special attention is given to the presence of illustrative examples, label classifications, and other microstructural information, assessing their contribution to user understanding.

By tracing changes in the treatment of humor, this study sheds light on broader trends in lexicography, such as the impact of cultural shifts, ideological influences, and evolving methodologies in dictionary-making. The findings highlight variations in definitional clarity, consistency, and depth, revealing how lexicographers negotiate meaning in response to linguistic and societal developments. Furthermore, the study considers the implications of these findings for modern lexicographic practice. Ultimately, this research contributes to discussions on the dynamic nature of word meaning and the interplay between lexicography and cultural perceptions of humor, offering insights into the evolving relationship between dictionaries and the societies they serve.},
