Abstract

The report reflects the Latvian scenario in co-operation for standardization of memory institutions. Differences and problems as well as benefits and possible solutions, tasks and activities of Standardization Technical Committee for Archives, Libraries and Museums Work (MABSTK) are analysed. Map of standards as a vision for ALM collaboration in standardization and "Digitizer's Handbook" (translated in English) prepared by the Competence Centre for Digitization of the National Library of Latvia (NLL) are presented. Shortcut to building the National Digital Library Letonica and its digital architecture (with pilot project about the Latvian composer Jazeps Vitols and the digital collection of expresident of Latvia Vaira Vike-Freiberga) reflects the practical co-operation between different players.

Abstract

Those in the openness movement believe that access to information is inherently democratic, and assume the effects of openness will all be good from the movement's perspective. But means are not ends, nothing is inevitable, and just what will be done with openly available information once achieved is rarely specified. One implicit goal of the openness movement is to create and sustain politically useful memory in situations in which official memory may not suffice, but to achieve this, openness is not enough. With the transition from a panopticon to a panspectron environment, the production of open information not only provides support for communities but also contributes to surveillance. Proprietary ownership of information is being challenged, but there is erosion of ownership in the sense of being confident in what is known. Some tactics currently in use need to be re-evaluated to determine their actual effects under current circumstances. Successfully achieving tactical memory in the 21st century also requires experimentation with new types of tactics, including those of technological discretion and of scale as a medium. At the most abstract level, the key political battle of the 21st century may not be between particular political parties or ideologies but, rather, the war between mathematics and narrative creativity.

Abstract

Large corpora are ubiquitous in today's world and memory quickly becomes the limiting factor in practical applications of the Vector Space Model (VSM). In this paper, we identify a gap in existing implementations of many of the popular algorithms, which is their scalability and ease of use. We describe a Natural Language Processing software framework which is based on the idea of document streaming, i.e. processing corpora document after document, in a memory independent fashion. Within this framework, we implement several popular algorithms for topical inference, including Latent Semantic Analysis and Latent Dirichlet Allocation, in a way that makes them completely independent of the training corpus size. Particular emphasis is placed on straightforward and intuitive framework design, so that modifications and extensions of the methods and/or their application by interested practitioners are effortless. We demonstrate the usefulness of our approach on a real-world scenario of computing document similarities within an existing digital library DML-CZ.

Abstract

In 2008 the FRBR/CRM Harmonisation Working Group has achieved a major milestone: a complete version of the object-oriented definition of FRBR (FRBRoo) was released for comment. After a brief overview of the history and context of the Working Group, this paper focuses on the primary contributions resulting from this work. - FRBRoo is a self-contained document which expresses the concepts of FRBR using the objectoriented methodology and framework of CIDOC CRM. It is an alternative view on library conceptualisation for a different purpose, not a replacement for FRBR. - This 'translation' process presented an opportunity to verify and confirm FRBR's internal consistency. - FRBRoo offers a common view of library and museum documentation as two kinds of information from memory institutions. Such a common view is necessary to provide interoperable information systems for all users interested in accessing common or related content. - The analysis provided an opportunity for mutual enrichment of FRBR and CIDOC CRM. Examples include: - - Addition of the modelling of time and events to FRBR, which can be seen in its application to the publishing process - - Clarification of the manifestation entity - - Explicit modelling of performances and recordings in FRBR - - Adding the work entity to CRM - - Adding the identifier assignment process to CRM. - Producing a formalisation which is more suited for implementation with object-oriented tools, and which facilitates the testing and adoption of FRBR concepts in implementations with different functional specifications and in different environments.

Abstract

This paper proposes the use of the Unified Modeling Language (UML) as a language for modelling ontologies for Web resources and the knowledge contained within them. To provide a mechanism for serialising and processing object diagrams representing knowledge, a pair of XSI-T stylesheets have been developed to map from XML Metadata Interchange (XMI) encodings of class diagrams to corresponding RDF schemas and to Java classes representing the concepts in the ontologies. The Java code includes methods for marshalling and unmarshalling object-oriented information between in-memory data structures and RDF serialisations of that information. This provides a convenient mechanism for Java applications to share knowledge on the Web

Abstract

In this paper, we provide an introduction to the concept of digital object reuse and its various connotations in the context of current digital libraries, archives, and repositories. We will then propose a faceted categorization of the various types, contexts, and cases for digital object reuse in order to facilitate understanding and communication and to provide a conceptual framework for the assessment of digital object reuse by various cultural heritage and cultural memory organizations.

Abstract

As traces of social life and material culture of the past, non-art images are carriers and prompters of memory. They are important sources for social and cultural history and, at the same time, valuable cultural heritage resources. Cultural heritage information systems (CHISs) very often rely on basic search and browsing features to provide access to information related to non-art digital images. However, these forms of access are not very helpful for non-expert or casual users, who usually move through the information space in an exploratory way. Although significant strides have been made to understand exploratory search activities, there are still some open issues when it comes to the user interface (UI). After briefly reviewing concept-based indexing techniques applied to images, this paper explores some of the questions related to UI design and provides insights into how to develop a browse-and-search framework to enhance exploratory search tasks.

Abstract

A basic distinction in agent-based data-driven Database Semantics (DBS) is between language and nonlanguage cognition. Language cognition transfers content between agents by means of raw data. Nonlanguage cognition maps between content and raw data inside the focus agent. {\it Recognition} applies a concept type to raw data, resulting in a concept token. In language recognition, the focus agent (hearer) takes raw language-data (surfaces) produced by another agent (speaker) as input, while nonlanguage recognition takes raw nonlanguage-data as input. In either case, the output is a content which is stored in the agent's onboard short term memory. {\it Action} adapts a concept type to a purpose, resulting in a token. In language action, the focus agent (speaker) produces language-dependent surfaces for another agent (hearer), while nonlanguage action produces intentions for a nonlanguage purpose. In either case, the output is raw action data. As long as the procedural implementation of place holder values works properly, it is compatible with the DBS requirement of input-output equivalence between the natural prototype and the artificial reconstruction.

Abstract

Today's semantic web deals with meaning in a very restricted sense and offers static solutions. This is adequate for many scientific, technical purposes and for business transactions requiring machine-to-machine communication, but does not answer the needs of culture. Science, technology and business are concerned primarily with the latest findings, the state of the art, i.e. the paradigm or dominant world-view of the day. In this context, history is considered non-essential because it deals with things that are out of date. By contrast, culture faces a much larger challenge, namely, to re-present changes in ways of knowing; changing meanings in different places at a given time (synchronically) and over time (diachronically). Culture is about both objects and the commentaries on them; about a cumulative body of knowledge; about collective memory and heritage. Here, history plays a central role and older does not mean less important or less relevant. Hence, a Leonardo painting that is 400 years old, or a Greek statue that is 2500 years old, typically have richer commentaries and are often more valuable than their contemporary equivalents. In this context, the science of meaning (semantics) is necessarily much more complex than semantic primitives. A semantic web in the cultural domain must enable us to trace how meaning and knowledge organisation have evolved historically in different cultures. This paper examines five issues to address this challenge: 1) different world-views (i.e. a shift from substance to function and from ontology to multiple ontologies); 2) developments in definitions and meaning; 3) distinctions between words and concepts; 4) new classes of relations; and 5) dynamic models of knowledge organisation. These issues reveal that historical dimensions of cultural diversity in knowledge organisation are also central to classification of biological diversity. New ways are proposed of visualizing knowledge using a time/space horizon to distinguish between universals and particulars. It is suggested that new visualization methods make possible a history of questions as well as of answers, thus enabling dynamic access to cultural and historical dimensions of knowledge. Unlike earlier media, which were limited to recording factual dimensions of collective memory, digital media enable us to explore theories, ways of perceiving, ways of knowing; to enter into other mindsets and world-views and thus to attain novel insights and new levels of tolerance. Some practical consequences are outlined.

The exact computations of the social brain, however, remain elusive. Here we investigated how the human br ain tracks ongoing changes in social relationships using functional neuroimaging. Participants were lead characters in a role-playing game in which they were to find a new home and a job through interactions with virtual cartoon characters. We found that a two-dimensional geometric model of social relationships, a "social space" framed by power and affiliation, predicted hippocampal activity. Moreover, participants who reported better social skills showed stronger covariance between hippocampal activity and "movement" through "social space." The results suggest that the hippocampus is crucial for social cognition, and imply that beyond framing physical locations, the hippocampus computes a more general, inclusive, abstract, and multidimensional cognitive map consistent with its role in episodic memory.].

Abstract

The range, depths and limits of what we know depend on the media with which we attempt to record our knowledge. This essay begins with a brief review of developments in a) media: stone, manuscripts, books and digital media, to trace how collections of recorded knowledge expanded to 235,000 in 1837 and have expanded to over 100 million unique titles in a single database including over 1 billion individual listings in 2007. The advent of digital media has brought full text scanning and electronic networks, which enable us to consult digital books and images from our office, home or potentially even with our cell phones. These magnificent developments raise a number of concerns and new challenges. An historical survey of major projects that changed the world reveals that they have taken from one to eight centuries. This helps explain why commercial offerings, which offer useful, and even profitable short-term solutions often undermine a long-term vision. New technologies have the potential to transform our approach to knowledge, but require a vision of a systematic new approach to knowledge. This paper outlines four ingredients for such a vision in the European context. First, the scope of European observatories should be expanded to inform memory institutions of latest technological developments. Second, the quest for a European Digital Library should be expanded to include a distributed repository, a digital reference room and a virtual agora, whereby memory institutions will be linked with current research;. Third, there is need for an institute on Knowledge Organization that takes up anew Otlet's vision, and the pioneering efforts of the Mundaneum (Brussels) and the Bridge (Berlin). Fourth, we need to explore requirements for a Universal Digital Library, which works with countries around the world rather than simply imposing on them an external system. Here, the efforts of the proposed European University of Culture could be useful. Ultimately we need new systems, which open research into multiple ways of knowing, multiple "knowledges". In the past, we went to libraries to study the recorded world. In a world where cameras and sensors are omnipresent we have new recording worlds. In future, we may also use these recording worlds to study the riches of libraries.
