Thesauri Design to improve access to Cartographic Heritage in the context of the Spatial Data Infrastructures

Tecnologías de la Información Geográfica, ontologías, Información Geográfica, interoperabilidad. The access of historians and document management specialists to documentary funds and old cartography is at times arduous due to the scattering of maps throughout different map libraries. Thus, it would be of interest to be able to access all available information remotely, following the Spatial Data Infrastructures (SDI) guidelines. DIGMAP is a cooperative project between six European countries that proposes to develop a solution for indexing, searching and browsing, through a thesaurus, in the European collections of digitized historical maps. It will be possible to match them with the geographic areas covered by each map in the collection and to find it on them, based on standard and open data models. These results will be useful for local digital map libraries, especially if it is of historical – cultural importance, or as interoperable components for wider and distributed systems. This project takes advantage of thesauri technologies to develop three major subsystems: On one hand, the gazetteer for managing and providing access to multilingual information relating to geographic features like geographic coordinates, names of places or areas and historical events related with the geographic points, places or areas (with dates or time intervals); The authority file to maintain and provide easy access to the author’s information and identification and disambiguating from similar and duplicate authors; and on the other hand, the map services for providing access to map information in raster and vector formats. The paper presents an early overview on the DIGMAP project, particularly focusing on the multilingual Thesauri aspects with the aim of providing solutions for the cartographic heritage framework, applying the main Spatial Data Infrastructures guidelines. ISO 19112 (Spatial Reference by Geographic Identifiers) will also be considered and its geographic identifiers issues

A geo-temporal information extraction service for processing descriptive metadata in digital libraries

In the context of digital map libraries, resources are usually described according to metadata records that define the relevant subject, location, time-span, format and keywords. On what concerns locations and time-spans, metadata records are often incomplete or they provide information in a way that is not machine-understandable (e.g. textual descriptions). This paper presents techniques for extracting geotemporal information from text, using relatively simple text mining methods that leverage on a Web gazetteer service. The idea is to go from human-made geotemporal referencing (i.e. using place and period names in textual expressions) into geo-spatial coordinates and time-spans. A prototype system, implementing the proposed methods, is described in detail. Experimental results demonstrate the efficiency and accuracy of the proposed approaches

A Guide to Distributed Digital Preservation

This volume is devoted to the broad topic of distributed digital preservation, a still-emerging field of practice for the cultural memory arena. Replication and distribution hold out the promise of indefinite preservation of materials without degradation, but establishing effective organizational and technical processes to enable this form of digital preservation is daunting. Institutions need practical examples of how this task can be accomplished in manageable, low-cost ways."--P. [4] of cove

The DIGMAP geo-temporal web gazetteer service

This paper presents the DIGMAP geo-temporal Web gazetteer service, a system providing access to names of places, historical periods, and associated geo-temporal information. Within the DIGMAP project, this gazetteer serves as the unified repository of geographic and temporal information, assisting in the recognition and disambiguation of geo-temporal expressions over text, as well as in resource searching and indexing. We describe the data integration methodology, the handling of temporal information and some of the applications that use the gazetteer. Initial evaluation results show that the proposed system can adequately support several tasks related to geo-temporal information extraction and retrieval

DiSCmap : digitisation of special collections mapping, assessment, prioritisation. Final project report

Traditionally, digitisation has been led by supply rather than demand. While end users are seen as a priority they are not directly consulted about which collections they would like to have made available digitally or why. This can be seen in a wide range of policy documents throughout the cultural heritage sector, where users are positioned as central but where their preferences are assumed rather than solicited. Post-digitisation consultation with end users isequally rare. How are we to know that digitisation is serving the needs of the Higher Education community and is sustainable in the long-term? The 'Digitisation in Special Collections: mapping, assessment and prioritisation' (DiSCmap) project, funded by the Joint Information Systems Committee (JISC) and the Research Information Network (RIN), aimed to:- Identify priority collections for potential digitisation housed within UK Higher Education's libraries, archives and museums as well as faculties and departments.- Assess users' needs and demand for Special Collections to be digitised across all disciplines.- Produce a synthesis of available knowledge about users' needs with regard to usability and format of digitised resources.- Provide recommendations for a strategic approach to digitisation within the wider context and activity of leading players both in the public and commercial sector.The project was carried out jointly by the Centre for Digital Library Research (CDLR) and the Centre for Research in Library and Information Management (CERLIM) and has taken a collaborative approach to the creation of a user-driven digitisation prioritisation framework, encouraging participation and collective engagement between communities.Between September 2008 and March 2009 the DiSCmap project team asked over 1,000 users, including intermediaries (vocational users who take care of collections) and end users (university teachers, researchers and students) a variety of questions about which physical and digital Special Collections they make use of and what criteria they feel must be considered when selecting materials for digitisation. This was achieved through workshops, interviews and two online questionnaires. Although the data gathered from these activities has the limitation of reflecting only a partial view on priorities for digitisation - the view expressed by those institutions who volunteered to take part in the study - DiSCmap was able to develop:- a 'long list' of 945 collections nominated for digitisation both by intermediaries andend-users from 70 HE institutions (see p. 21);- a framework of user-driven prioritisation criteria which could be used to inform current and future digitisation priorities; (see p. 45)- a set of 'short lists' of collections which exemplify the application of user-driven criteria from the prioritisation framework to the long list (see Appendix X):o Collections nominated more than once by various groups of users.o Collections related to a specific policy framework, eg HEFCE's strategically important and vulnerable subjects for Mathematics, Chemistry and Physics.o Collections on specific thematic clusters.o Collections with highest number of reasons for digitisation

Linking archival data to location A case study at the UK National Archives

Purpose The National Archives (TNA) is the UK Government's official archive. It stores and maintains records spanning over a 1,000 years in both physical and digital form. Much of the information held by TNA includes references to place and frequently user queries to TNA's online catalogue involve searches for location. The purpose of this paper is to illustrate how TNA have extracted the geographic references in their historic data to improve access to the archives. Design/methodology/approach To be able to quickly enhance the existing archival data with geographic information, existing technologies from Natural Language Processing (NLP) and Geographical Information Retrieval (GIR) have been utilised and adapted to historical archives. Findings Enhancing the archival records with geographic information has enabled TNA to quickly develop a number of case studies highlighting how geographic information can improve access to large‐scale archival collections. The use of existing methods from the GIR domain and technologies, such as OpenLayers, enabled one to quickly implement this process in a way that is easily transferable to other institutions. Practical implications The methods and technologies described in this paper can be adapted, by other archives, to similarly enhance access to their historic data. Also the data‐sharing methods described can be used to enable the integration of knowledge held at different archival institutions. Originality/value Place is one of the core dimensions for TNA's archival data. Many of the records which are held make reference to place data (wills, legislation, court cases), and approximately one fifth of users' searches involve place names. However, there are still a number of open questions regarding the adaptation of existing GIR methods to the history domain. This paper presents an overview over available GIR methods and the challenges in applying them to historical data

Mapping the Current Landscape of Research Library Engagement with Emerging Technologies in Research and Learning: Final Report

The generation, dissemination, and analysis of digital information is a significant driver, and consequence, of technological change. As data and information stewards in physical and virtual space, research libraries are thoroughly entangled in the challenges presented by the Fourth Industrial Revolution:1 a societal shift powered not by steam or electricity, but by data, and characterized by a fusion of the physical and digital worlds.2 Organizing, structuring, preserving, and providing access to growing volumes of the digital data generated and required by research and industry will become a critically important function. As partners with the community of researchers and scholars, research libraries are also recognizing and adapting to the consequences of technological change in the practices of scholarship and scholarly communication. Technologies that have emerged or become ubiquitous within the last decade have accelerated information production and have catalyzed profound changes in the ways scholars, students, and the general public create and engage with information. The production of an unprecedented volume and diversity of digital artifacts, the proliferation of machine learning (ML) technologies,3 and the emergence of data as the “world’s most valuable resource,”4 among other trends, present compelling opportunities for research libraries to contribute in new and significant ways to the research and learning enterprise. Librarians are all too familiar with predictions of the research library’s demise in an era when researchers have so much information at their fingertips. A growing body of evidence provides a resounding counterpoint: that the skills, experience, and values of librarians, and the persistence of libraries as an institution, will become more important than ever as researchers contend with the data deluge and the ephemerality and fragility of much digital content. This report identifies strategic opportunities for research libraries to adopt and engage with emerging technologies,5 with a roughly fiveyear time horizon. It considers the ways in which research library values and professional expertise inform and shape this engagement, the ways library and library worker roles will be reconceptualized, and the implication of a range of technologies on how the library fulfills its mission. The report builds on a literature review covering the last five years of published scholarship, primarily North American information science literature, and interviews with a dozen library field experts, completed in fall 2019. It begins with a discussion of four cross-cutting opportunities that permeate many or all aspects of research library services. Next, specific opportunities are identified in each of five core research library service areas: facilitating information discovery, stewarding the scholarly and cultural record, advancing digital scholarship, furthering student learning and success, and creating learning and collaboration spaces. Each section identifies key technologies shaping user behaviors and library services, and highlights exemplary initiatives. Underlying much of the discussion in this report is the idea that “digital transformation is increasingly about change management”6 —that adoption of or engagement with emerging technologies must be part of a broader strategy for organizational change, for “moving emerging work from the periphery to the core,”7 and a broader shift in conceptualizing the research library and its services. Above all, libraries are benefitting from the ways in which emerging technologies offer opportunities to center users and move from a centralized and often siloed service model to embedded, collaborative engagement with the research and learning enterprise

Development and evaluation of a geographic information retrieval system using fine grained toponyms

Geographic information retrieval (GIR) is concerned with returning information in response to an information need, typically expressed in terms of a thematic and spatial component linked by a spatial relationship. However, evaluation initiatives have often failed to show significant differences between simple text baselines and more complex spatially enabled GIR approaches. We explore the effectiveness of three systems (a text baseline, spatial query expansion, and a full GIR system utilizing both text and spatial indexes) at retrieving documents from a corpus describing mountaineering expeditions, centred around fine grained toponyms. To allow evaluation, we use user generated content (UGC) in the form of metadata associated with individual articles to build a test collection of queries and judgments. The test collection allowed us to demonstrate that a GIR-based method significantly outperformed a text baseline for all but very specific queries associated with very small query radii. We argue that such approaches to test collection development have much to offer in the evaluation of GIR

Role of Librarian in Internet and World Wide Web Environment

The transition of traditional library collections to digital or virtual collections presented the librarian with new opportunities. The Internet, Web environment and associated sophisticated tools have given the librarian a new dynamic role to play and serve the new information based society in better ways than hitherto. Because of the powerful features of Web i.e. distributed, heterogeneous, collaborative, multimedia, multi-protocol, hypermedia- oriented architecture, World Wide Web has revolutionized the way people access information, and has opened up new possibilities in areas such as digital libraries, virtual libraries, scientific information retrieval and dissemination. Not only the world is becoming interconnected, but also the use of Internet and Web has changed the fundamental roles, paradigms, and organizational culture of libraries and librarians as well. The article describes the limitless scope of Internet and Web, the existence of the librarian in the changing environment, parallelism between information science and information technology, librarians and intelligent agents, working of intelligent agents, strengths, weaknesses, threats and opportunities involved in the relationship between librarians and the Web. The role of librarian in Internet and Web environment especially as intermediary, facilitator, end-user trainer, Web site builder, researcher, interface designer, knowledge manager and sifter of information resources is also described
