Interactive entertainment permits users to participate actively. In this paper, we consider the importance of cinematic presentation in internet-based interactive entertainment. We propose that a tool for the artistic and technical representation of presentation-layer demands of interactive entertainment already exists: a system called DirectorNotation. This system can provide the ability for the creation of artistically significant, adaptive, context sensitive, interactive, actionable multimedia content. In the work that has been presented so far on DirectorNotation, the applications that are considered target the professional film director in his filming activities to produce better results, or consider the “Artificial Intelligence” possibilities of exploiting a knowledge model of film directing. In this paper, we aim to create a connection to the domain of interactive entertainment, showing that this application area can achieve highly promising improvements by exploiting the suggested technology combination.

Nowadays, computer games entertain millions of computer users. They support incredible 3D graphics that attract players. However, cinematic presentation in computer games is missing. There are technologies and rules for camerawork and lighting that are not exploited by game engines. In this paper, we demonstrate some problems that computer games suffer from, at the presentation level, and we examine a new research project, called ANSWER, as a potential solution to those problems. ANSWER attempts to cover the expressive needs of film directors and game animators, by providing a set of tools that will allow the description of a game or a film at the artistic level and during its production phase.

In the present paper we explore Ontologies, as a means to capture knowledge of the film-making domain. More specifically, we intend to open a discussion so as to guide the development of DirectorNotation, an under-development open-source tool for representing media content, as of its pre-production and production phases, using a symbolic notation system, in which a film director can formally record his intentions. DirectorNotation’s authors suggest Ontologies for formalizing and reasoning over their notation system. The current paper discusses this technical choice, considering its limitations, and makes suggestions about the work that needs to be performed if these limitations are to be overcome.

Within the scope of ANSWER, an EC-supported research project, a new artistic notation system, called DirectorNotation, is being developed for describing media content, much like notes are used to document a music composition. Our current research focuses on developing “notation-enabled” offline authoring tools, but interactive applications are an anticipated extension. Here, we summarise the key aspects of DirectorNotation and the ANSWER project, from the point of view of a multimedia-technology audience interested in content-based manipulation of media.

Based on current trends in the domain of Cultural Heritage promotion, visitors seek to engage in exceptional and unique experiences beyond established visiting practices. Meanwhile, the latest developments in information and communication facilitate access to cultural databases and repositories, bringing out the potential of new cultural products and services. In this direction, a variety of typologies and visitor categorizations have been developed that however do not take into account the complexity of visitors’ demands and motivations, or that visitors tend to experience a journey based on new technologies and social media. Semantic Web technologies could be the key for designing personalized services, among other things, facilitating data interoperability in different repositories, making possible the correlation of data with different visitor profiles. In this context, Intelligent Interaction research group works towards an innovative approach that will enrich and enhance the e...

We introduce M(krDSL), an agile Knowledge Engineering methodology. It addresses the Knowledge Acquisition bottleneck. The point of differentiation of M(krDSL) from previous practice involves knowledge engineers and domain experts collaborating extremely closely: "The domain expert constructs the model. The model is independently useful as a communication tool." We introduce two additional layers of abstraction between human domain experts and operational software: a shared Knowledge Model of the domain, and Visualisation mockups/prototypes. Tools of the methodology include: DSLs and graphical representations; Qualitative analysis of the DSLs; Semantic Metadata for Test Driven Design; and analysis of concurrently evolving Visualisation output mockups/prototypes. In our experience, following this methodology helped us escape from situations where we had completely ceased to be able to make any modelling progress at all, while even at times when we were able to make easy progress in our KE tasks, M(krDSL) gave us a high degree of confidence in the correct prioritisation and correct results of our work.

The Cultural Heritage (CH) domain encompasses a wide range of different disciplines, serving the study, interpretation, curation, and preservation of objects, collections, archives, sites, and the dissemination of related knowledge. In this context, stakeholders generate, retrieve, and share a vast amount of diverse information. Therefore, information interoperability has been considered a crucial task, especially in terms of semantics. In this way, the CIDOC CRM (International Committee for Documentation Conceptual Reference Model) has been widely used as an underlying model that offers interoperability between CH domain metadata standards and ontologies. To the best of our knowledge, an overall review of mapping, merging, and extending this core ontology, as well as an aggregate table which classifies and correlates those ontologies and standards, has not yet been presented. Our study conducts an aggregate review of relevant published efforts and outlines the various associations ...

The modern cultural industry and the related academic sectors have shown increased interest in Cultural User eXperience (CUX) research, since it constitutes a critical factor to examine and apply when presenting cultural content. Recent CUX studies show that visitors tend to carry their own cultural characteristics and preferences when visiting destinations of cultural interest, thus obtaining a virtually unique experience. To cope with this tendency, various research efforts have been made to identify different profiles of cultural visitors based on their background and preferences and classify them into distinct visitor types. In this paper, we proposed the ACUX (Augmented Cultural User eXperience) typology for classifying visitors of cultural destinations. The proposed typology aims to provide the multi-profile classification of cultural visitors based on their visiting preferences. Methodology-wise, the ACUX typology was the output of a harmonisation process of existing cultural...

Early, effective director-producer communication enables detection of resource-demanding film production requirements so that a workable production plan can be formed. Traditional communication tools are limited to articulating standard production elements as lists. Yet, production complexity can be affected by latent variables with indirect impact which remain unarticulated. An ontology-driven, interactive visualization system is proposed for exposing production complexity. The system is built upon a visual language for recording directorial choices, employed for system input. By exploiting Ontologies, the visual input is analyzed in real-time and semantic metadata are extracted representing production complexity with focus on latent variables. The metadata are transformed back into an aggregate visual form which combines with the visual input, creating useful synergies. In this way, the system creates a collaborative virtual workspace facilitating director-producer communications....

Over the last decade, the Cultural Heritage (CH) domain has gradually adopted Semantic Web (SW) technologies for organizing information and for tackling interoperability issues. Several semantic models have been proposed which accommodate essential aspects of information management: retrieval, integration, reuse and sharing. In this context, the CH subdomain of Conservation and Restoration (CnR) exhibits an increasing interest in SW technologies, in an attempt to effectively handle the highly heterogeneous and often secluded CnR information. This paper investigates semantic models relevant to the CnR knowledge domain. The scope, development methodology and coverage of CnR aspects are described and discussed. Furthermore, the evaluation, deployment and current exploitation of each model are examined, with focus on the types and variety of services provided to support the CnR professional. Through this study, the following research questions are investigated: To what extent the variou...

In recent years, Recommendation Systems (RSs) have gained popularity in different scientific fields through the creation of (mostly mobile) applications that deliver personalized services. A mobile recommendation system (MRS) that classifies in situ visitors according to different visiting profiles could act as a mediator between their visiting preferences and cultural content. Drawing on the above, in this paper, we propose ACUX Recommender (ACUX-R), an MRS, for recommending personalized cultural POIs to visitors based on their visiting preferences. ACUX-R experimentally employs the ACUX typology for assigning profiles to cultural visitors. ACUX-R was evaluated through a user study and a questionnaire. The evaluation conducted showed that the proposed ACUX-R satisfies cultural visitors and is capable of capturing their nonverbal visiting preferences and needs.

Open laboratories (OpenLabs) in Cultural Heritage institutions are an effective way to provide visibility into the behind-the-scenes processes and promote documentation data collected and produced by domain specialists. However, presenting these processes without proper explanation or communication with specialists may cause issues in terms of visitors’ understanding. To support OpenLabs and disseminate information, digital media and efficient data management can be utilized. The CAnTi (Conservation of Ancient Tiryns) project seeks to design and implement virtual and mixed reality applications that visualize conservation and restoration data, supporting OpenLab operations at the Acropolis of Ancient Tiryns. Semantic Web technologies will be used to model the digital content, facilitating organization and interoperability with external sources in the future. These applications will be part of the OpenLab activities on the site, enhancing visitors’ experiences and understanding of cur...
