    In this paper, we present an efficient deep learning based approach to extract technology-related topics and keywords within scientific literature, and identify corresponding technologies within patent applications. Specifically, we utilize transformer based language models, tailored for use with scientific text, to detect coherent topics over time and describe these by relevant keywords that are automatically extracted from a large text corpus. We identify these keywords using Named Entity Recognition, distinguishing between those describing methods, applications and other scientific terminology. We create a large amount of search queries based on combinations of method- and application-keywords, which we use to conduct semantic search and identify related patents. By doing so, we aim at contributing to the growing body of research on text-based technology mapping and forecasting that leverages latest advances in natural language processing and deep learning. We are able to map technologies identified in scientific literature to patent applications, thereby providing an empirical foundation for the study of science-technology linkages. We illustrate the workflow as well as results obtained by mapping publications within the field of neuroscience to related patent applications.

    Authors: Hain, Daniel; Jurowetzki, Roman; Buchmann, Tobias; Wolf, Patrick;

    Patent data has long been used as a widely accessible measure of therate and direction of technological change. However, this long tradition of research hasso far focused on producing and analyzing measures of patent quantity, assuming thenumber of patents produced to accurately capture the rate of progress and innovationoutput. Existing attempts to measure patent quality are mostly limited to the use offorward- and backward citation pattern. In contrast, in this paper, we derive a patentquality indicator by leveraging the rich but up to now under-utilized textual informationin patent abstracts. We employ vector space modeling techniques to create a highdimensionalvector representation of the patents to capture their technological signature.Using almost near linear-scaling approximate nearest neighbor matching techniques, weare able to compute dyadic similarity scores across large bodies of patent data. Based onthe temporal distribution of a patents similarity scores, we compute ex-ante indicatorsof a patentÂťs technological novelty and ex-post indicators of technological impact andsignificance. At the case of circa 132.000 electro-mobility patents, we demonstrate theproposed indicators‘ to map, analyze, and predict patent quality on individual, firm, andcountry level, and its development over time.

    Authors: Pedersen, Poul;

    Bidraget opstiller en definition af den arkitekturhistoriske fase, som tager sin begyndelse omkring 370 f.Kr. under satrappen Maussollos og i vidt omfang kommer til at bestemme udviklingen af Lilleasiens monumentalarkitektur i to århundreder derefter. Den forsøges her for første gang behandlet henholdsvist i sin formative begyndelse under Hekatomnidedynastiet og adskilt herfra i sin post-Hekatomnidiske videreførelse.

    Authors: Samman, Nadim; Trittin, Jürgen; Taita;

    In a historical moment gripped by environmental catastrophes of our own making, Julius von Bismarck confronts the forces of nature at their unruly extremes. Deploying sculpture, photography, video and technological devices designed to harness the elements, Bismarck stills water droplets and fragments of exploding stone, shaping them into slow-motion disasters calibrated to the rate of human perception. Through performative encounters with lightning, wildfires, hurricanes and ocean waves, the artist stages a timely reckoning with the fate of age-old ideas of nature. Following a forward by museum director Susanne Pfleger, Talking to Thunder explores the implications of Bismarck’s latest work through essays by philosopher Dehlia Hannah and curator Nadim Samman, interviews with Wiwa shaman Taita, Jurgen Trittin of the German Green Party, and fire historian Stephen Pyne, and excerpts from Gaston Bachelard and Max Frisch.

    This paper presents the first results of a study of pottery evidence from a new archaeological project being conducted at the site of Tepe Gryashan located in the province of Kurdistan, western Iran. The collected pottery, including Sprig ware-like sherds and Flint-scraped Coba bowls, are rare evidence of material culture contact with northern Mesopotamia from the early Late Chalcolithic period.

    This article focuses on the dialogue between Intangible Cultural Heritage (ICH) and technology, specifically within the domain of traditional craftsmanship. We begin by establishing the current methods of safeguarding traditional crafts, as described in previous issues of this journal, and the benefits and limitations of these. This is followed by an introduction to the concept of digitisation and the Tripartite Digitisation Model (TDM) for capturing, representing and disseminating ICH through digital means. Through a case study of digitising a traditional joinery technique, we explore different methods for capturing data about ICH and reflect on their use for digitisation. The ICH is represented through 3D models, video clips and audio voice-over, and disseminated in an interactive VR simulation. After evaluating the simulation with the people whose ICH we were trying to safeguard, we discuss the benefits and limitations of moving the ICH from its original context into a digital one.

    Patent data has long been used as a widely accessible measure of therate and direction of technological change. However, this long tradition of research hasso far focused on producing and analyzing measures of patent quantity, assuming thenumber of patents produced to accurately capture the rate of progress and innovationoutput. Existing attempts to measure patent quality are mostly limited to the use offorward- and backward citation pattern. In contrast, in this paper, we derive a patentquality indicator by leveraging the rich but up to now under-utilized textual informationin patent abstracts. We employ vector space modeling techniques to create a highdimensionalvector representation of the patents to capture their technological signature.Using almost near linear-scaling approximate nearest neighbor matching techniques, weare able to compute dyadic similarity scores across large bodies of patent data. Based onthe temporal distribution of a patents similarity scores, we compute ex-ante indicatorsof a patentÂťs technological novelty and ex-post indicators of technological impact andsignificance. At the case of circa 132.000 electro-mobility patents, we demonstrate theproposed indicators‘ to map, analyze, and predict patent quality on individual, firm, andcountry level, and its development over time.

    Authors: Pedersen, Poul;

    Bidraget opstiller en definition af den arkitekturhistoriske fase, som tager sin begyndelse omkring 370 f.Kr. under satrappen Maussollos og i vidt omfang kommer til at bestemme udviklingen af Lilleasiens monumentalarkitektur i to århundreder derefter. Den forsøges her for første gang behandlet henholdsvist i sin formative begyndelse under Hekatomnidedynastiet og adskilt herfra i sin post-Hekatomnidiske videreførelse.

    Authors: Samman, Nadim; Trittin, Jürgen; Taita;

    In a historical moment gripped by environmental catastrophes of our own making, Julius von Bismarck confronts the forces of nature at their unruly extremes. Deploying sculpture, photography, video and technological devices designed to harness the elements, Bismarck stills water droplets and fragments of exploding stone, shaping them into slow-motion disasters calibrated to the rate of human perception. Through performative encounters with lightning, wildfires, hurricanes and ocean waves, the artist stages a timely reckoning with the fate of age-old ideas of nature. Following a forward by museum director Susanne Pfleger, Talking to Thunder explores the implications of Bismarck’s latest work through essays by philosopher Dehlia Hannah and curator Nadim Samman, interviews with Wiwa shaman Taita, Jurgen Trittin of the German Green Party, and fire historian Stephen Pyne, and excerpts from Gaston Bachelard and Max Frisch.

    This paper presents the first results of a study of pottery evidence from a new archaeological project being conducted at the site of Tepe Gryashan located in the province of Kurdistan, western Iran. The collected pottery, including Sprig ware-like sherds and Flint-scraped Coba bowls, are rare evidence of material culture contact with northern Mesopotamia from the early Late Chalcolithic period.
