“…However, this requires an excellent knowledge of the topic and some information may not be found at all. Especially, the following four issues still persist in many libraries and archives (Evens & Hauttekeete, 2011): This leads to the two main problems of finding and afterward publishing the relevant data. Even in recent research, it is often necessary to collect analog data and process it.…”

This contribution shows the comparison, investigation, and implementation of different access strategies on multimodal data. The first part of the research is structured as a theoretical part opposing and explaining the terms of conventional access, virtual archival access, and virtual museums while additionally referencing related work. Especially, issues that still persist in repositories like the ambiguity or missing of metadata is pointed out. The second part explains the practical implementation of a workflow from a large image repository to various four-dimensional applications. Mainly, the filtering of images and in the following, the orientation of images is explained. Selection of the relevant images is partly done manually but also with the use of deep convolutional neural networks for image classification. In the following, photogrammetric methods are used for finding the relative orientation between image pairs in a projective frame. For this purpose, an adapted Structure from Motion (SfM) workflow is presented, in which the step of feature detection and matching is replaced by the Radiant-Invariant Feature Transform (RIFT) and Matching On Demand with View Synthesis (MODS). Both methods have been evaluated on a benchmark dataset and performed superior than other approaches. Subsequently, the oriented images are placed interactively and in the future automatically in a 4D browser application showing images, maps, and building models Further usage scenarios are presented in several Virtual Reality (VR) and Augmented Reality (AR) applications. The new representation of the archival data enables spatial and temporal browsing of repositories allowing the research of innovative perspectives and the uncovering of historical details.Highlights:<ul><li>Strategies for a completely automated workflow from image repositories to four-dimensional (4D) access approaches.</li><li>The orientation of historical images using adapted and evaluated feature matching methods.</li><li>4D access methods for historical images and 3D models using web technologies and Virtual Reality (VR)/Augmented Reality (AR).</li></ul>

“…A way to conserve cultural heritage and ensure permanent access to information is through digital preservation and CH institutions should act on that. According to Evens and Hauttekeete [43], governments have a crucial role in opening their archives and digitalizing them. This could facilitate the accessibility of heritage exhibits and collections.…”

Current technological advancements offer many ways of enhancing disabled peoples' access to Cultural Heritage environments. A new generation of Social Computing technologies and systems is changing the way in which we access Cultural Heritage, facilitating the inclusion of socially isolated groups of people. Under this perspective, this paper aims to explore the potential impact of Social Computing systems to enhance people' access to Cultural Heritage, particularly focusing on deaf and disabled users. By reviewing the current literature on Social Computing and Cultural Heritage, the paper first summarizes the related applications and appropriate key technologies; second, it provides examples of innovative approaches to the enhancement of user-engagement and interaction through social computing. Moreover, the paper highlights arising issues of privacy, as well as ethical considerations, and presents design principles for ensuring privacy. The study concludes by discussing challenges for inclusive Social Computing applications in the context of Cultural Heritage and pointing out areas where future research is needed.

Moreover, the paper highlights arising issues of privacy, as well as ethical considerations, and presents design principles for ensuring privacy. The study concludes by discussing challenges for inclusive Social Computing applications in the context of Cultural Heritage and pointing out areas where future research is needed.[1]. Based on the literature, SC can be interactive and collaborative as it facilitates communication between people. SC environments allow people to interact in many different ways. Examples of SC technologies include social media sites and networks, e-mail, discussion forums, blogs, wikis, instant messaging, games, and open-source development.More recently, the rise of SC tools has influenced information systems and applications and strongly received researchers' attention with a particular interest to its social implications for helping people access Cultural Heritage environments [2]. Indeed, social technologies, and especially social media applications, affect both access to and the character of the cultural activity. Cultural Heritage (CH) constitutes an interdisciplinary area...

“…A great number of publicly funded digitization projects have produced numerous repositories, digital libraries, archives and publishing platforms. Key factors in achieving the appropriate return from the corresponding investments are i) ensuring, to the greatest extent possible, the quality of the output at the level of both the metadata records and the digital files, ii) establishing actions towards the digital long-term preservation of the content [23], iii) ensuring interoperability for systems and content (including provision via open APIs according to established standards, use of standard metadata and file formats etc. ), iv) setting clear licences for the digital resources, preferably open access licenses when possible v) establishing large-scale national and international aggregation schemes that offer central access to the fragmented contentthus increasing its discoverability and re-use potentials -and often set specifications and guides with good practices that boost all previous factors [1][21] [22].…”

Most aggregators face challenges regarding searchability, discoverability and visual presentation of their content due to metadata heterogeneity across the collections. Particularly for cultural and historical material, keyword-based searching is far from sufficient. Structured item types and temporal information are key metadata for the discoverability of cultural heritage content. We developed an innovative metadata enrichment and homogenization scheme for types and temporal information that is both effective and user-friendly and we embedded it in the ingestion workflow of SearchCulture.gr, the greek cultural heritage aggregator developed by the National Documentation Centre (EKT). Two key components of the enrichment scheme are Semantics.gr, a platform for publishing vocabularies that contains a mapping tool for massive semantic enrichment, and a parametric tool for chronological normalization. We enriched and homogenized the aggregated content with respect to types and temporal information which subsequently allowed us to develop advanced multilingual search and browsing features, including hierarchical navigation on types and historical periods, searching and faceting on types, time spans and historical periods, a tag cloud of types and an interactive timeline/histogram.
