Computer Vision and Architectural History at Eye Level:Mixed Methods for Linking Research in the Humanities and in Information Technology

Information on the history of architecture is embedded in our daily surroundings, in vernacular and heritage buildings and in physical objects, photographs and plans. Historians study these tangible and intangible artefacts and the communities that built and used them. Thus valuableinsights are gained into the past and the present as they also provide a foundation for designing the future. Given that our understanding of the past is limited by the inadequate availability of data, the article demonstrates that advanced computer tools can help gain more and well-linked data from the past. Computer vision can make a decisive contribution to the identification of image content in historical photographs. This application is particularly interesting for architectural history, where visual sources play an essential role in understanding the built environment of the past, yet lack of reliable metadata often hinders the use of materials. The automated recognition contributes to making a variety of image sources usable forresearch.<br/

Mixing Methods: Practical Insights from the Humanities in the Digital Age

The digital transformation is accompanied by two simultaneous processes: digital humanities challenging the humanities, their theories, methodologies and disciplinary identities, and pushing computer science to get involved in new fields. But how can qualitative and quantitative methods be usefully combined in one research project? What are the theoretical and methodological principles across all disciplinary digital approaches? This volume focusses on driving innovation and conceptualising the humanities in the 21st century. Building on the results of 10 research projects, it serves as a useful tool for designing cutting-edge research that goes beyond conventional strategies

Field sketching and the interpretation of landscape : exploring the benefits of fieldwork and drawing in contemporary landscape practice

This thesis explores potential roles for field sketching in, landscape observation and assessment, landscape planning and design, landscape representation, and in addressing the experiential dimension of the landscape.The research seeks to define and legitimise the old technique of field sketching, and the use and development of field sketches by students and practitioners of landscape architecture, and other landscape disciplines. The wider values of, fieldwork, hand -generated field notations, drawing as an interactive dialogue with others, and the sketch as a type of landscape representation, are also recognised.Whilst accurate representation and precise geometrical definition of the landscape can now be achieved quickly with photographs and by semi - automated digital means, interpretation requires careful observation. Sketching involves an observer stopping and looking and interpreting slowly and carefully. Field sketching and the uses of the field sketch are proposed as bringing an effectiveness to landscape work, valuable because of the interpretation it involves, and the time it does take: timeless because of its simplicity.A personal way of working is investigated, based on a Grounded Theory approach. Systematic analysis of case studies is made through reflection-on-practice. Practice observations (data) are collated and interpreted by practical sorting tasks, to propose a series of how to do and why important principles regarding field sketching. External support for the research findings is sought from literature, considering the broad themes of: fieldwork and the experience of landscapes, field sketching and drawing as craft and expression, and developing and using field sketches.Applications for field sketching to meet contemporary needs in landscape architecture are proposed: the sketch as a designer's tool, sketch-based visualisations as interpretive images, and field sketching as a participative technique that can be used to engage the inquirer, collaborators, and the public with landscape experience -grounded decisions

Geographies of botanical knowledge: the work of John Hutton Balfour 1845-1879

This thesis forms a contribution to the historical geography of botanical knowledge. It examines the writings, teaching and public engagement in botany of John Hutton Balfour (1808-1884), Regius Professor of Botany and Medicine at the University of Edinburgh and Regius Keeper of the Royal Botanic Garden Edinburgh (RBGE) between 1845 and 1879. The thesis explores the methods and approaches used by Balfour to promote botany. It pays specific attention to his scientific correspondence, publications, teaching and pedagogical practices (including fieldwork) and to his role in promoting the Botanical Society of Edinburgh. The curriculum Balfour constructed covered the major aspects of nineteenth-century botanical knowledge: plant structure, morphology and classification as well as aspects then ‘on the fringes’ of becoming popular – plant physiology. In order to teach this curriculum, Balfour meticulously shaped scientific, pedagogic and social spaces into places of scientific production and discovery. Study of his published work, classroom, field sites and involvement with the public sphere together form the principal elements of this thesis. These are the central places and productive sites in which his botany was made. Balfour’s published work allowed him to develop theoretical aspects in his view of botany. For Balfour, writing was an occupation about which he cared deeply both in terms of its role in knowledge circulation but also from a personal perspective. His publication of texts suitable for several distinct audiences (while financially rewarding,) was also an excellent method of circulating botanical and religious knowledge, two topics he was passionate to promote. The classroom provided the setting for Balfour to teach through practical instruction. He employed sensory stimulating objects in order to encourage students to learn the skill of botanical identification and observation. The ‘field’, like the classroom, was also a site of practical instruction. Balfour’s construction of ‘the field’ was careful and deliberate. It was based on familiarity of location, experience of working in the field, and an extensive knowledge of the geographical distribution of plants in Scotland. Balfour’s engagement with the public was evident in his involvement with the Botanical Society of Edinburgh (BSE), and by lectures delivered to groups with the object of moral improvement through botany. The thesis situates Balfour’s work within recent literature on the historical geography of scientific knowledge, with particular attention to the importance of place and the sites of science’s making. In this way, Balfour’s work is illustrative of wider elements of the situated production, and variable dissemination, of scientific (botanical) knowledge

Transnational Scottish Book Marketing to a Diasporic Audience, 1995-2015

The thesis examines transnational Scottish book marketing to a diasporic audience from 1995 to 2015. The study addresses the research question: what makes marketing of Scottish-interest books from Small to Medium Enterprises (SMEs) in the publishing industry successful transnationally? The data underlying the research comes from semi-structured interviews with members of publishing organisations in Scotland and members of Scottish heritage organisations worldwide, case studies of the marketing histories of economically successful books targeting the diaspora, and narrative rhetorical criticism of the online book blurbs of Scottish-interest books by Scottish publishers. The qualitative results demonstrate that the marketing of Scottish-interest books from SMEs in the publishing industry is successful transnationally when creative relationship marketing through storytelling is emphasised; icons, symbols and narratives from Scotland’s place brand are utilised; and communication of value is targeted to specific subcultures of consumption (like the Scottish diaspora) that transcend national boundaries. Adopting the definition of marketing as the communication of value of a product or service, the study analyses the influencers, characteristics, and participants of that communication. The research impacts those individuals and organisations, particularly Scottish publishing companies, who are involved in the twenty-first century Scottish book trade. The thesis recommends that to reach the diaspora audience, Scottish publishers need to make a more united effort under Publishing Scotland to approach and partner with Scottish heritage organisations; create working relationships with Global Scot (and Scottish Enterprise more generally), Scottish Development International, Visit Scotland, and Event Scotland; and become more involved in tourism events relating to the Scottish diaspora

Knowledge-based and data-driven approaches for geographical information access

Geographical Information Access (GeoIA) can be defined as a way of retrieving information from textual collections that includes the automatic analysis and interpretation of the geographical constraints and terms present in queries and documents. This PhD thesis presents, describes and evaluates several heterogeneous approaches for the following three GeoIA tasks: Geographical Information Retrieval (GIR), Geographical Question Answering (GeoQA), and Textual Georeferencing (TG). The GIR task deals with user queries that search over documents (e.g. ¿vineyards in California?) and the GeoQA task treats questions that retrieve answers (e.g. ¿What is the capital of France?). On the other hand, TG is the task of associate one or more georeferences (such as polygons or coordinates in a geodetic reference system) to electronic documents. Current state-of-the-art AI algorithms are not yet fully understanding the semantic meaning and the geographical constraints and terms present in queries and document collections. This thesis attempts to improve the effectiveness results of GeoIA tasks by: 1) improving the detection, understanding, and use of a part of the geographical and the thematic content of queries and documents with Toponym Recognition, Toponym Disambiguation and Natural Language Processing (NLP) techniques, and 2) combining Geographical Knowledge-Based Heuristics based on common sense with Data-Driven IR algorithms. The main contributions of this thesis to the state-of-the-art of GeoIA tasks are: 1) The presentation of 10 novel approaches for GeoIA tasks: 3 approaches for GIR, 3 for GeoQA, and 4 for Textual Georeferencing (TG). 2) The evaluation of these novel approaches in these contexts: within official evaluation benchmarks, after evaluation benchmarks with the test collections, and with other specific datasets. Most of these algorithms have been evaluated in international evaluations and some of them achieved top-ranked state-of-the-art results, including top-performing results in GIR (GeoCLEF 2007) and TG (MediaEval 2014) benchmarks. 3) The experiments reported in this PhD thesis show that the approaches can combine effectively Geographical Knowledge and NLP with Data-Driven techniques to improve the efectiveness measures of the three Geographical Information Access tasks investigated. 4) TALPGeoIR: a novel GIR approach that combines Geographical Knowledge ReRanking (GeoKR), NLP and Relevance Feedback (RF) that achieved state-of-the-art results in official GeoCLEF benchmarks (Ferrés and Rodríguez, 2008; Mandl et al., 2008) and posterior experiments (Ferrés and Rodríguez, 2015a). This approach has been evaluated with the full GeoCLEF corpus (100 topics) and showed that GeoKR, NLP, and RF techniques evaluated separately or in combination improve the results in MAP and R-Precision effectiveness measures of the state-of-the-art IR algorithms TF-IDF, BM25 and InL2 and show statistical significance in most of the experiments. 5) GeoTALP-QA: a scope-based GeoQA approach for Spanish and English and its evaluation with a set of questions of the Spanish geography (Ferrés and Rodríguez, 2006). 6) Four state-of-the-art Textual Georeferencing approaches for informal and formal documents that achieved state-of-the-art results in evaluation benchmarks (Ferrés and Rodríguez, 2014) and posterior experiments (Ferrés and Rodríguez, 2011; Ferrés and Rodríguez, 2015b).L'Accés a la Informació Geogràfica (GeoAI) pot ser definit com una forma de recuperar informació de col·lecions textuals que inclou l'anàlisi automàtic i la interpretació dels termes i restriccions geogràfiques que apareixen en consultes i documents. Aquesta tesi doctoral presenta, descriu i avalua varies aproximacions heterogènies a les seguents tasques de GeoAI: Recuperació de la Informació Geogràfica (RIG), Cerca de la Resposta Geogràfica (GeoCR), i Georeferenciament Textual (GT). La tasca de RIG tracta amb consultes d'usuari que cerquen documents (e.g. ¿vinyes a California?) i la tasca GeoCR tracta de recuperar respostes concretes a preguntes (e.g. ¿Quina és la capital de França?). D'altra banda, GT es la tasca de relacionar una o més referències geogràfiques (com polígons o coordenades en un sistema de referència geodètic) a documents electrònics. Els algoritmes de l'estat de l'art actual en Intel·ligència Artificial encara no comprenen completament el significat semàntic i els termes i les restriccions geogràfiques presents en consultes i col·leccions de documents. Aquesta tesi intenta millorar els resultats en efectivitat de les tasques de GeoAI de la seguent manera: 1) millorant la detecció, comprensió, i la utilització d'una part del contingut geogràfic i temàtic de les consultes i documents amb tècniques de reconeixement de topònims, desambiguació de topònims, i Processament del Llenguatge Natural (PLN), i 2) combinant heurístics basats en Coneixement Geogràfic i en el sentit comú humà amb algoritmes de Recuperació de la Informació basats en dades. Les principals contribucions d'aquesta tesi a l'estat de l'art de les tasques de GeoAI són: 1) La presentació de 10 noves aproximacions a les tasques de GeoAI: 3 aproximacions per RIG, 3 per GeoCR, i 4 per Georeferenciament Textual (GT). 2) L'avaluació d'aquestes noves aproximacions en aquests contexts: en el marc d'avaluacions comparatives internacionals, posteriorment a avaluacions comparatives internacionals amb les col·lections de test, i amb altres conjunts de dades específics. La majoria d'aquests algoritmes han estat avaluats en avaluacions comparatives internacionals i alguns d'ells aconseguiren alguns dels millors resultats en l'estat de l'art, com per exemple els resultats en comparatives de RIG (GeoCLEF 2007) i GT (MediaEval 2014). 3) Els experiments descrits en aquesta tesi mostren que les aproximacions poden combinar coneixement geogràfic i PLN amb tècniques basades en dades per millorar les mesures d'efectivitat en les tres tasques de l'Accés a la Informació Geogràfica investigades. 4) TALPGeoIR: una nova aproximació a la RIG que combina Re-Ranking amb Coneixement Geogràfic (GeoKR), PLN i Retroalimentació de Rellevancia (RR) que aconseguí resultats en l'estat de l'art en comparatives oficials GeoCLEF (Ferrés and Rodríguez, 2008; Mandl et al., 2008) i en experiments posteriors (Ferrés and Rodríguez, 2015a). Aquesta aproximació ha estat avaluada amb el conjunt complert del corpus GeoCLEF (100 topics) i ha mostrat que les tècniques GeoKR, PLN i RR avaluades separadament o en combinació milloren els resultats en les mesures efectivitat MAP i R-Precision dels algoritmes de l'estat de l'art en Recuperació de la Infomació TF-IDF, BM25 i InL2 i a més mostren significació estadística en la majoria dels experiments. 5) GeoTALP-QA: una aproximació basada en l'àmbit geogràfic per espanyol i anglès i la seva avaluació amb un conjunt de preguntes de la geografía espanyola (Ferrés and Rodríguez, 2006). 6) Quatre aproximacions per al georeferenciament de documents formals i informals que obtingueren resultats en l'estat de l'art en avaluacions comparatives (Ferrés and Rodríguez, 2014) i en experiments posteriors (Ferrés and Rodríguez, 2011; Ferrés and Rodríguez, 2015b)
