abstract = {Social media platforms can be used as a tool to expand awareness and the consideration of cultural heritage organizations and their activities in the digital world. These platforms produce daily behavioral analytical data that could be exploited by the administrators of libraries, archives and museums (LAMs) to improve users’ engagement with the provided published content. There are multiple papers regarding social media utilization for improving LAMs’ visibility of their activities on the Web. Nevertheless, there are no prior efforts to support social media analytics to improve users’ engagement with the content that LAMs post to social network platforms. In this paper, we propose a data-driven methodology that is capable of (a) providing a reliable assessment schema regarding LAMs Facebook performance page that involves several variables, (b) examining a more extended set of LAMs social media pages compared to other prior investigations with limited samples as case studies, and (c) understanding which are the administrators’ actions that increase the engagement of users. The results of this study constitute a solid stepping-stone both for practitioners and researchers, as the proposed methods rely on data-driven approaches for expanding the visibility of LAMs services on the Social Web.},

abstract = {Cataloging and metadata description is one of the major competencies that a trainee cataloger must conquer. According to recent research results, library and information studies students experience difficulties understanding the theory, the terminology, and the tools necessary for cataloging. The experimental application of teaching models which derive from predominant learning theories, such as behaviorism, cognitivism, and constructivism, may help in detecting the difficulties of a cataloging course and in suggesting efficient solutions. This paper presents in detail three teaching models applied for a cataloging course and investigates their effectiveness, based on a survey of 126 first-year students. The survey employed the Kirkpatrick model aiming to record undergraduate students’ perceptions and feelings about cataloging. The results revealed that, although a positive change in students’ behavior towards cataloging has been achieved, they still do not feel very confident about the skills they have acquired. Moreover, students felt that practicing cataloging more frequently will eliminate their difficulties. Finally, they emphasized the need for face to face courses, as the survey took place in the coronavirus pandemic, during which the courses were held via distance learning.},

abstract = {Extensive research on mobile guides for museums has explored the potential of technology to offer some of the services that have been traditionally provided by human guides, including guiding visitors in the museum space, providing information about the exhibits, and using more advanced interpretative approaches such as digital storytelling and gamified techniques. However, the majority of these approaches either ignores or tries to substitute entirely the role of the human guide. In this work, we present a user study with 10 experienced tour guides, currently working in the museum of modern art of the Basil & Elise Goulandris Foundation. Based on a three-phase procedure, the study is designed to empower professionals into envisaging their work in symbiosis with current technological developments. First, we attempt to identify existing challenges guides face and to capture their tacit knowledge in addressing emerging problems in guided tours. In the second and third stage, through a reflective and productive discussion, we employ a set of contemporary innovative digital applications as a starting point to elicit their views on their role in an envisaged symbiotic future of human-led hybrid digital experiences.},

abstract = {Purpose

The study aims to explore Greek libraries’ social media presence and library operation and social media use during the coronavirus disease 2019 (COVID-19) lockdown.



Design/methodology/approach

Primary data were collected via an online questionnaire that was distributed to the Greek libraries. The final sample comprised 189 libraries of all types with the exception of school libraries.



Findings

Results indicated that Facebook is the most widely used platform, while social media are mainly used for sharing announcements about library operations and for the promotion of events. During the COVID-19 lockdown, libraries responded quickly to the new circumstances by taking many of their services online. However, they did not fully use social media for service provision but rather used social media as a static communication channel. Only a few of the libraries grasped the opportunity to highlight their role in the promotion of public health by providing timely and reliable information.



Practical implications

Library leaders who are looking to harness the power of social media for service promotion and outreach should build a strategy that takes platform popularity, current social media trends, patron preferences and the specific promotional objectives of their library into consideration.



Originality/value

To the best of the authors’ knowledge, the current research is the first which attempts to explore the social media presence of Greek libraries of all types and changes made to library operations and social media use in response to the COVID-19 lockdown.},

However, negative experiences associated with social networking, such as fatigue and overload, can lead to SNS abandonment. Given the widespread utilization of social media by libraries of all types, user discontinuance decisions are crucial to the formulation of libraries’ digital marketing strategy. In this context, this study investigates public library patrons’ intention to discontinue using Facebook, permanently or intermittently, and/or replace it with another network. Preferences regarding the content posted by libraries are also examined, as it has been found to affect social media fatigue and abandonment.},

abstract = {Purpose

University Archives (UA) are the bridge between the past and the present and serve as a beacon for highlighting the contribution of academic institutions to society. Although the UA topic was introduced and formalized in the 1950s, the scientific research interest has increased significantly in the past two decades. This paper aims to provide insights into the UA research topic during the previous 15 years.



Design/methodology/approach

The combination of two well-established methods for performing literature review was deployed, aiming to identify, select and assess the research documents. Based on the selection criteria, 49 documents presenting research efforts around the UA topic were finally examined from the Scopus citation index. The selected studies have been classified into three main topics: strategic management of UA and the derived challenges, the educational contribution of UA and the strategic information systems for UA.



Findings

Some of the main findings are the lack of well-defined administrative policies, the low level of awareness and archival consciousness within the universities, the inadequacy of university archivists’ educational and training background, the need to use UA for building relationships with alumni and society, and finally, the need for metadata standardization by the UA management systems.



Originality/value

As a literature review around UA has not been conducted before, the reader will gain insights into the methods and research designs that other scholars had already applied to designate useful findings and results.},

Design/methodology/approach

A review of the literature and a quantitative survey was conducted, based on a structured questionnaire, with a response rate of 44.7%.



Findings

Among the crucial issues that should be taken seriously into consideration when transiting into a new and shared LMS, are the audit of the data quality before migration, the employees' training design and the composition of the LMS central support team. The benefits of a shared LMS are mainly effectiveness in terms of libraries' budgets and time for the employees' day-to-day work.



Originality/value

The survey presented in this article evaluates the merits of a shared LMS and contributes innovative aspects to the existing bibliography by investigating issues and problems that arose during the transition. This way, the professionals involved in similar initiatives will benefit by avoiding possible mistakes and drawbacks when implementing such a project.},

Nevertheless, recent research results indicate the managerial difficulties in deploying strategies for expanding the discoverability, visibility, and accessibility of these websites. In this paper, a three-stage data-driven Search Engine Optimization schema is proposed to assess the performance of Libraries, Archives, and Museums websites (LAMs), thus helping administrators expand their discoverability, visibility, and accessibility within the Web realm. To do so, the authors examine the performance of 341 related websites from all over the world based on three different factors, Content Curation, Speed, and Security. In the first stage, a statistically reliable and consistent assessment schema for evaluating the SEO performance of LAMs websites through the integration of more than 30 variables is presented. Subsequently, the second stage involves a descriptive data summarization for initial performance estimations of the examined websites in each factor is taking place. In the third stage, predictive regression models are developed to understand and compare the SEO performance of three different Content Management Systems, namely the Drupal, WordPress, and custom approaches, that LAMs websites have adopted. The results of this study constitute a solid stepping-stone both for practitioners and researchers to adopt and improve such methods that focus on end-users and boost organizational structures and culture that relied on data-driven approaches for expanding the visibility of LAMs services.},

A quantitative survey was conducted based on a structured questionnaire, with 179 valid responses. The participants in the survey agreed with the Open Peer Review principles. However, they ignored basic terms like FAIR (Findable, Accessible, Interoperable, and Reusable) and appeared incentivized to permit the exploitation of their data. Regarding Open Peer Review (OPR), participants expressed their agreement, implying their support for a trustworthy evaluation system. Conclusively, researchers need to receive proper training for both Open Research Data principles and Open Peer Review processes which combined with a reformed evaluation system will enable them to take full advantage of the opportunities that arise from the new scholarly publishing and communication landscape},

abstract = {Abstract: The present study focuses on spatiotemporal historical data organized in an OWL Protégé ontology environment. It aims at exploring the possibilities of using deduction logic tools in correlating alternate names of geographic regions related to time periods and presenting spatiotemporal interconnections. The application paradigm includes spatial data of local regions and sites of contemporary Greece and Turkey related to Hellenic historical archaeological sites temporally distributed in an extended period from Neolithic Age to the 19th century. The results are presented through advanced visualization tools embedded in the Protégé environment.



Purpose: The present study focuses on spatiotemporal historical data organized in an OWL Protégé ontology environment. It aims at exploring the possibilities of using deduction logic tools in correlating alternate names of geographic regions related to time periods and presenting spatiotemporal interconnections.



Design/methodology/approach: Methodology follows the systematic review paradigm and includes the development of a protocol for the following elements. Protocol for the inclusion of different types of entities. Protocol for the ways of standard use and expansion, in this case TNG and AAT vocabularies. Protocol for the description of entities within the ontological framework and finally a set of rules for the selection of vocabularies and authority tools. Literature search was conducted grouped in units to the corresponding protocols and likewise research results were tested per protocol.



Findings: The central idea of this study was the exploitation of embodied Deduction Logic tools in an ontology environment in order to reveal evolutionary history topics (as the relation of historical named entities based on their temporal features), as well as to connect historical monuments to places described by their real then used name apart from their contemporary identification.



Originality/value: The work could have a practical informational application as its ability to connect to google maps and Wikipedia and other linked data can turn it into a useful information tool.



This work can also be used as a paradigm for cooperation between humanities and computational semantics, since there are a lot of available techniques that can enrich the information research and retrieval in digital humanities repositories, leading to the emergence of ‘hidden’ treasures in contexts not studied and exploited yet.},

abstract = {Acquiring knowledge about users’ opinion and what they say regarding specific features within an app, constitutes a solid steppingstone for understanding their needs and concerns. App review utilization helps project management teams to identify threads and opportunities for app software maintenance, optimization and strategic marketing purposes. Nevertheless, app user review classification for identifying valuable gems of information for app software improvement, is a complex and multidimensional issue. It requires foresight and multiple combinations of sophisticated text pre-processing, feature extraction and machine learning methods to efficiently classify app reviews into specific topics. Against this backdrop, we propose a novel feature engineering classification schema that is capable to identify more efficiently and earlier terms-words within reviews that could be classified into specific topics. For this reason, we present a novel feature extraction method, the DEVMAX.DF combined with different machine learning algorithms to propose a solution in app review classification problems. One step further, a simulation of a real case scenario takes place to validate the effectiveness of the proposed classification schema into different apps. After multiple experiments, results indicate that the proposed schema outperforms other term extraction methods such as TF.IDF and χ2 to classify app reviews into topics. To this end, the paper contributes to the knowledge expansion of research and practitioners with the purpose to reinforce their decision-making process within the realm of app reviews utilization.},

abstract = {Purpose – This article aims to detail a plan for the application of the  PLUS  information  literacy  model  in  the  context  of  a  prison library.  A  brief  overview  of  the  literature  will  highlight  the importance of (co-)developing activities based on multiple models and learning theories. At the same time, the article argues in favour of  the  idea  that  the  implementation  of  information  literacy programmes in the  context  of  excluded  and  socially  vulnerable groups can substantially help to improve their self-image and their smooth integration within the restrictive walls of the prison, as well enhancing their capability of returning to society and functioning as law-abiding members.. This will be followed by a presentation of the steps for implementing such a work plan in a prison library, with the  aim  of  helping  second  chance  school  learners  prepare  a presentation  on  racism.  The  article  is  based  on  an  assignment prepared for the “Information Literacy” course at the Department of  Archival,  Library  &  Information  Studies,  during the  spring semester of the 2019-2020 academic year. 



Design/methodology/approach - The  research  hypothesis  for the project is situated within the context of a prison library. There, the educator teaching the subject of Sociology (Social Literacy) at the Second Chance School (SCS), will express their wish that each learner prepares a presentation - on the subject of discrimination (e.g. gender, political beliefs, religion, social exclusion, minorities, etc.).  To  this  end, the  educator will  propose  that  learners  seek guidance from the librarian on a topic pertinent to the concept of discrimination (racism). The approach followed by learners when preparing their presentation will be based on the PLUS model of information literacy. Subsequently, the steps taken by the librarian will be presented to them, and their choices will be justified on the basis of the literature concerning the design of learning processes. Methodologically,  the  study  is  based  on  the  synthesis  of fundamental theories of adult education with the PLUS information literacy model. 



indings - The development of work plans in an informational organisation environment, inspired by microteaching, can serve as a  good  example  for  promoting  the  application  of  informational models to their operation and services. This article, presenting every step of this process, can serve as a pilot for the application of a work plan by educators and information scientists. Originality/value - There are few examples of applications of informational  models  in  educational  processes  for  socially vulnerable or excluded groups. This article also enhances awareness on issues pertaining to libraries and education within prisons not just in Greece, but also abroad. Let us not forget that, in the 21st century,  there  still  exist  countries  in  which  the  human  rights  to education  and  information  for  detained  people  are  still  being violated.  },

managing knowledge, the study also looks at the reinterpretations of users, and their needs for information

with wholeness and expanding mechanisms. Furthermore, the persistence of the core concept is regarded as its

continuous life in time and space. The example of the plant decoration has its roots in archaeological findings

and incorporates several scientific aspects (art, botany, history, archaeology, geography, geology, chemistry)

and it is used here as a tester for exploring the informational capability of mind maps within the digital

environment.

Methodology follows the systematic review paradigm and includes the development of a protocol for the

following elements: protocol for the inclusion of different types of entities. Protocol for the ways of standard

use and expansion, in this case CIDOC CRM augmented by TNG and AAT vocabularies. Protocol for the

description of entities within the ontological framework and finally a set of rules for the selection of

vocabularies and authority tools.

Literature search will be conducted grouped in units to the corresponding protocols and likewise research

results will be tested per protocol.},

abstract = {During the past few decades, it seems that personalizing and adjusting the e-courses’ content based on individual learning styles is rather important. Indeed, several studies have been carried out throughout the years regarding the a priori personalization and adjustment of e-courses systems. This way modern LMSs (Learning Management Systems) could identify beforehand the learning styles of the e-course attendants and adjust the lesson content flow and type based on personal learning styles. Nevertheless, little bibliography exists on how to assess the compatibility level between educational content and learning styles dimensions of an LMS, in a real-life environment.  With the above thoughts in mind, the current work attempts to introduce and verify an innovative framework for the students' learning styles and e-courses compatibility assessment, based on the content type and volume. The proposed framework is validated through its application at an LMS in a real-life academic environment. Such an approach could be very beneficial for already deployed e-courses on LMSs that aim to differentiate educational content provision based on users’ profiles.},

abstract = {In the Big Data era, search engine optimization deals with the encapsulation of datasets that are related to website performance in terms of architecture, content curation, and user behavior, with the purpose to convert them into actionable insights and improve visibility and findability on the Web. In this respect, big data analytics expands the opportunities for developing new methodological frameworks that are composed of valid, reliable, and consistent analytics that are practically useful to develop well-informed strategies for organic traffic optimization. In this paper, a novel methodology is implemented in order to increase organic search engine visits based on the impact of multiple SEO factors. In order to achieve this purpose, the authors examined 171 cultural heritage websites and their retrieved data analytics about their performance and user experience inside them. Massive amounts of Web-based collections are included and presented by cultural heritage organizations through their websites. Subsequently, users interact with these collections, producing behavioral analytics in a variety of different data types that come from multiple devices, with high velocity, in large volumes. Nevertheless, prior research efforts indicate that these massive cultural collections are difficult to browse while expressing low visibility and findability in the semantic Web era. Against this backdrop, this paper proposes the computational development of a search engine optimization (SEO) strategy that utilizes the generated big cultural data analytics and improves the visibility of cultural heritage websites. One step further, the statistical results of the study are integrated into a predictive model that is composed of two stages. First, a fuzzy cognitive mapping process is generated as an aggregated macro-level descriptive model. Secondly, a micro-level data-driven agent-based model follows up. The purpose of the model is to predict the most effective combinations of factors that achieve enhanced visibility and organic traffic on cultural heritage organizations’ websites. To this end, the study contributes to the knowledge expansion of researchers and practitioners in the big cultural analytics sector with the purpose to implement potential strategies for greater visibility and findability of cultural collections on the Web.},

It has therefore become necessary for them to seek alternative sources of income. One such strategy could be commercial advertising, which constitutes the renting of space within or outside the library or using the library’s website to place ads. However, an application of commercial advertising in libraries can trigger negative reactions from library patrons. In this context, the aim of this paper is to investigate stakeholders' views regarding the use of commercial advertising by Greek libraries, using a quantitative methodology. The results reveal that commercial advertising is considered as a profitable strategy for Greek libraries by both respondent groups, information professionals and users, alike.},

The survey was conducted in October 2019 and it is a comparative study of a previous research-survey (about the eClass) of 2012.



Design/methodology/approach - The questionnaire, consisted of open and closed-ended questions, and were sent respectively to the undergraduate and postgraduate students and the faculty’s staff (or professors) of the Department. As a result, 275 valid answers (233 undergraduates and 42 postgraduates’ valid responses) translated to a net response rate of 39%, while the faculty survey returned 29 valid answers with a 100% participation rate.



Findings - The findings demonstrate that the students and the faculty agree that the eClass is essential for the Department’s courses and program (undergraduate and postgraduate). The communication and the interactions between the eClass platform and the users (faculty and students) has been very well established. Finally, the more interesting result that revealed from the regression analysis that was conducted, is that the more recent registration by the users (student and faculty), the more they visit the platform (eClass) and the higher they appreciated the system’s functionalities aspect.



Originality/value – Useful findings were extracted regarding the evaluation of ALIS Dept eClass, after (almost) ten years of implementation. Useful comparison was made with the previous evaluation in 2012 and joined results extracted. The opinions gathered from the undergraduate and postgraduates’ students, and the faculty, reveal that the strategic goal of the ALIS Dept to use the eClass as a centralized component for the studies in the Dept, is a sophisticated choice.},

Design/methodology/approach - In this work, the results of accelerated ageing on pure cellulose paper in sealed vessels are reported. The properties studied include the degree of polymerization (which was converted to the percentage of broken glyosidic bonds), the tearing resistance, the pH and the L* and b* coordinates of the CIEL*a*b* color system. Ageing was performed in sealed vessels at 90°C και 76% RH for periods of 20, 40, 60, 80, 100, 120 and 140 days.



Findings - The results indicated an overall deterioration of all paper properties, which accelerates with time because of the production of volatile acidic species (autocatalysis). The evolution of paper properties through time was modeled efficiently by use of the equations proposed by Zervos and Moropoulou (2005) for the autocatalytic acid hydrolysis of pure cellulose paper, which were shown that also apply for following the changes of tearing resistance. The applicability of the model equations was also verified for other paper properties, such as the percentage of broken bonds (δ%) and the L* and b* coordinates of the CIEL*a*b* color system.},

abstract = {This study considers the expressiveness (that is, the expressive power or expressivity) of different types of Knowledge Organization Systems (KOS) and discusses its potential to be machine-processable in the context of the semantic web. For this purpose, the theoretical foundations of KOS are reviewed based on conceptualizations introduced by the Functional Requirements for Subject Authority Data (FRSAD) and the Simple Knowledge Organization System (SKOS); natural language processing techniques are also implemented. Applying a comparative analysis, the dataset comprises a thesaurus (Eurovoc), a subject headings system (LCSH) and a classification scheme (DDC). These are compared with an ontology (CIDOC-CRM) by focusing on how they define and handle concepts and relations. It was observed that LCSH and DDC focus on the formalism of character strings (nomens) rather than on the modelling of semantics; their definition of what constitutes a concept is quite fuzzy, and they comprise a large number of complex concepts. By contrast, thesauri have a coherent definition of what constitutes a concept, and apply a systematic approach to the modelling of relations. Ontologies explicitly define diverse types of relations, and are by their nature machine-processable. The paper concludes that the potential of both the expressiveness and machine processability of each KOS is extensively regulated by its structural rules. It is harder to represent subject headings and classification schemes as semantic networks with nodes and arcs, while thesauri are more suitable for such a representation. In addition, a paradigm shift is revealed which focuses on the modelling of relations between concepts, rather than the concepts themselves.},
