This document discusses enriching Linked Open Data with distributional semantics to study concept drift. It describes what concept drift is, how it affects Linked Open Data applications like semantic annotation and ontology matching, and how distributional semantics can help detect changes in word meanings over time. The document presents a method for linking distributional semantics data to Linked Open Data using a data model that represents change scores for words between decades. This combined data allows querying to analyze which domains, concepts, or word categories exhibit the most drift.

Abstract. Since its creation 350 years ago, the scientific peer-reviewed journal has become the central and most important form of scholarly communication in the natural sciences and medicine. Although the digital revolution has facilitated and accelerated the publishing process by moving from print to online, it has not changed the scientific journal and scholarly communication as such. Today publications and citations in peer-reviewed journals are considered as indicators of scientific productivity and impact and used and misused in research evaluation. As scholarly communication is becoming more open and diverse and manuscripts, data, presentations and code are shared online, the altmetrics and open science movement demand the adaption of evaluation practices. Parallels are drawn between the early days of bibliometrics and current altmetrics research highlighting possibilities and limitations of various metrics and warning against adverse effects.
The document provides an overview of what life was like for soldiers living in trenches during World War 1. It describes trenches as long narrow ditches dug for shelter from enemy fire, with the German and Allied trenches on opposite sides separated by no man's land. Life in the trenches was difficult, as soldiers lived in cold, muddy conditions without proper sanitation or sleeping accommodations. Trenches were infested with rats carrying disease, and soldiers faced the constant threat of attack when going over the top into no man's land.
This document provides an overview of approaches to narrative research. It discusses the diversity of understandings of "narrative" in both popular and academic contexts. In social research, narrative has become a popular approach but offers little guidance on methods. The document examines different focuses of narrative research, from micro-level event narratives to larger cultural narratives. It also addresses issues around collecting, analyzing, and interpreting narrative data, as well as theoretical assumptions underlying different perspectives in narrative research.
This document discusses knowledge artefacts such as ontologies and vocabularies. It begins by asking whether an ontology is needed for a particular case and then defines what an ontology is - a specification of a conceptualization of a knowledge domain using a controlled vocabulary. It distinguishes ontologies from other knowledge artefacts like thesauri and taxonomies. The document notes there are different approaches to building ontologies such as top-down, bottom-up and middle-out. It also provides examples of existing biomedical ontologies and vocabularies.
The document provides an overview of ontology and its various aspects. It discusses the origin of the term ontology, which derives from Greek words meaning "being" and "science," so ontology is the study of being. It distinguishes between scientific and philosophical ontologies. Social ontology examines social entities. Perspectives on ontology include philosophy, library and information science, artificial intelligence, linguistics, and the semantic web. The goal of ontology is to encode knowledge to make it understandable to both people and machines. It provides motivations for developing ontologies such as enabling information integration and knowledge management. The document also discusses ontology languages, uniqueness of ontologies, purposes of ontologies, and provides references.

This document discusses challenges to scientific integrity and debates around defining scientific misconduct. It makes three key points:
1) Even defining scientific integrity and misconduct has been disputed, as core definitions are complex and have changed over time based on influential cases.
2) Explaining the causes of scientific misconduct and defining good scientific practices is difficult, as intentions and behaviors exist on a spectrum rather than clear categories.
3) While ethics courses may have limited efficacy, discussions of ethics and guidelines are still important to reinforce scientific values and build trust in science. However, universities will need innovative new approaches to truly improve ethics.
This document discusses conceptualizing 'cultural frames of reference' and 'cross-cultural frames of reference' and how employing these concepts can bring about social and cultural change in different societies. It defines cultural frame of reference as the sum total of an individual's enculturation experience and mindset shaped by their unique cultural context. Cross-cultural frame of reference refers to aspects of cultural frames that can be applied across cultures. The author argues that understanding these concepts is important for interpreting issues from a multicultural perspective and addressing complex problems in cultural contexts.
Elsevier aims to construct knowledge graphs to help address challenges in research and medicine. Knowledge graphs link entities like people, concepts, and events to provide answers. Elsevier analyzes text and data to build knowledge graphs using techniques like information extraction, machine learning, and predictive modeling. Their knowledge graph integrates data from publications, clinical records, and other sources to power applications that help researchers, medical professionals, and patients. Knowledge graphs are a critical component for delivering value, especially as data volumes and needs accelerate.
This study investigated how religious practice can systematically change the way people visually attend to stimuli. Specifically, it found that the "global precedence effect" (better performance on global vs. local features) was significantly reduced in Calvinism, a religion emphasizing individual responsibility, and increased in Catholicism and Judaism, religions emphasizing social solidarity. It also found this effect was long-lasting and varied depending on the amount and strictness of religious practices, suggesting religious practice induces attentional control styles that create biases in visual attention.
The document discusses bibliographic coupling, co-citation coupling, and obsolescence. It defines bibliographic coupling as the relationship between two works that cite a common work, and co-citation coupling as the relationship between two works that are both cited by a third work. It outlines criticisms of bibliographic coupling and describes how co-citation coupling and author co-citation analysis evolved as alternative methods. Uses of bibliographic coupling include finding related research and understanding the development of new subjects. The document also defines obsolescence as the reduced use of information over time, and lists reasons for and criteria to measure the declination in usage of information.
CDAO presentation.
The idea of the comparative analysis ontoloty has been presented worldwide, including: NESCent (USA), IGBMC (France), UFRJ (Brazil). Providing a semantic framework for evolutionary analysis in a high-throughtput way after the next and third generation sequencing is the way to approach evolutionary-based studies into genome-wide analysis. The darwinian core of reasoning also allows CDAO to be used with other entities.
Drifting distributions? Possibilities and risks of using distributional seman...Antske Fokkens
This document discusses using distributional semantics to study concept drift. It explains key concepts like intension, extension, and labels that define concepts. Distributional semantics represents words as vectors based on co-occurrence. This approach has been used to detect semantic change but has limitations for concept drift which involves broader changes. Control words and different models are needed to reliably study how relations between concepts change over time.
Cultural Contradictions of Scanning in an Evidence-based Policy EnvironmentWendy Schultz
Dr. Wendy L. Schultz discusses horizon scanning as an essential tool for foresight activities that identifies emerging issues and changes. However, scanning faces challenges in an evidence-based policy environment due to contradictions between the subjective, tentative nature of scanning and political and scientific desires for objective, authoritative conclusions. Various techniques like causal layered analysis, integral futures, and spiral dynamics can help overcome biases and validate scan findings from diverse sources to better identify surprises and alternatives for policymaking.
This document provides an introduction to communication theory. It discusses what constitutes a good theory, noting criteria like theoretical scope, appropriateness, heuristic value, validity, parsimony, and openness. A theory should generally explain phenomena broadly, make logical assumptions, suggest avenues for further research, be logically consistent and falsifiable, provide simple explanations, and allow for compatibility with other theories. The document also distinguishes theories from models, noting that models provide simplified representations of communication processes.
This is an intro to Primer in Theory Construction by Paul Reynolds. Presented in Faculty of Entrepreneurship University of Tehran. Advanced Theories of Management( Dr.Arabiun)
Writing an essay on evolution is challenging as it requires understanding complex biological principles, navigating vast research from different scientific fields, and addressing social implications. The topic spans millions of years and diverse species, making it difficult to concisely cover in an essay. Researching evolution demands meticulously examining scholarly articles and staying up-to-date on latest findings. Crafting a coherent essay on evolution necessitates scientific knowledge, analytical skills, and effectively communicating this expansive topic.

should scientist embrace realist or antirealistManuel Marozwa
This article analyzes whether scientists should embrace scientific realism or antirealism to further scientific progress. It discusses the perspectives of scientific realism, which claims theories can explain observable and unobservable phenomena, versus antirealism, which limits theories to only predicting observables. The author uses a cost-benefit analysis to examine how each view is impacted by scientific revolutions. However, the analysis does not clearly favor one view over the other. The article ultimately concludes scientific realism may better enable scientific progress since theories can be used to explain unobservables, unlike under antirealism.
The Degree Of Innovation: Through Incremental To RadicalDmytro Shestakov
Innovation is one of the most important forms of expanding the economic system's capabilities and competitiveness in a modern, dynamic world. Since the beginning of the 20th century, the theory of innovation has been developing, changing, and improving significantly and many scientific papers have been created on the topic of types of innovation. However, even today, scientists are confused in basic concepts, replacing one with another and taking one for the other without proper and inﰀ depth terminology understanding. Although from innovation direction point of view, there is a clear distinction between types, some uncertainty in the levels (degrees) of innovations is present. For many years there have been many differences in the scientific literature, which significantly influenced both the inﰀdepth understanding of the innovation concept and the quality of approaches to assessing the levels of innovation. The purpose of this paper is to inﰀdepth review the literature on innovation types to identify approaches that emphasize the degree of innovation. We considered the different conclusions of the researchers step by step and argue that there is the problem of identifying one or another innovation in terms of its degree and find the disagreements in the scientific literature in basic concepts to understand high degree innovation. The most complete and extended definitions of incremental, semiﰀradical, radical, disruptive, and breakthrough innovation were proposed as well as Degree of Innovation matrix was created to clearly demonstrate the existing distinctive features of each individual degree of innovation. This paper contributes to the theoretical analysis of the impact of innovative knowledge, as well as broadens previously published scientific literature, analyzing its impact on understanding the types and degrees of innovation, as well as the relationships, characteristics and key differences between them. The results of the research is the conceptual basis supported by the scientific literature for the modern understanding of terminology in the field of innovation activities.

The document discusses the multi-level nature of science. It describes how science works at different scales, from individual scientists tackling specific problems to broad overarching theories that frame entire disciplines. Hypotheses aim to explain narrow phenomena, while theories provide broad explanations supported by evidence. Some theories, like evolution or plate tectonics, are so important that they establish frameworks for understanding the natural world. Even accepted theories may change over time with new evidence. The document uses examples like the discovery of ozone depletion by CFCs to illustrate how science is an iterative process dependent on evidence and the scientific community.
This document provides a definition of what constitutes a worldview. It defines a worldview as a coherent collection of concepts that allows one to construct a global image of the world and understand many elements of experience. It identifies six fundamental philosophical questions that a worldview seeks to address: what exists, where it comes from, where it is going, what is good/evil, how we should act, and what is true/false. The document discusses how different academic disciplines relate to answering these questions and forming a worldview. It proposes that developing a scientific worldview could integrate different fields through systems theory, problem-solving approaches, and evolutionary theory.
Theory of paradoxes and contradictory rule sets FINAL FINAL FINAL FINAL FINAL...Sujay Rao Mandavilli
This paper seeks to meaningfully complement many of our earlier and previously published papers on
scientific method and the philosophy of science among which were our papers on the social
responsibility of researchers, science activism, the sociological ninety ten rule, the certainty uncertainty
principle, cross-cultural research design, output criteria driven scientific hypothesis formulation,
horizontal collaboration etc., and is intended to help produce better scientific theories and hypotheses
in general and led to scientific endeavour that is of a fundamentally higher order as well. It will, we
expect and anticipate, catapult scientific activity to an altogether higher domain and sphere given that a
proactive quest for paradoxes is at the heart of our approach, and is also resultantly expected to be an
intrinsic part of formal, structured and pre-defined scientific method in future. It therefore forms an
essential and an integral part of our globalization of science movement as well, given the fact that multicultural and inter-disciplinary approaches to science are likely to throw up more paradoxes as well, and
literally up the ante too by leading to scientific activity that is of a fundamentally higher order. We begin
this paper by getting down to brass stacks and attempting a basic definition of the widely used term
“paradox” and reviewing older literature in this regard in different contexts. We also lay bare the
essentials of our approach, and enunciate the postulates and canons that form a part of our paper, so
that the entire philosophy driving this paper, i.e., its philosophical foundation, in clearly grasped and
understood by those to whom it is intended.
Creating and Analysing Linked Open Data for the EU ParliamentLaura Hollink
The document discusses creating linked open data from speeches and transcripts of the European Parliament. It describes the data structure for representing a speech as linked data, including properties like the speaker, date, title, text in multiple languages, and links to other speeches. It also discusses linking the data to external sources to identify speakers and add additional context about countries.
Guest Lecture: Linked Open Data for the Humanities and Social SciencesLaura Hollink
The document discusses two projects, PoliMedia and Talk of Europe, that link government data to news data as linked open data. PoliMedia links speeches from the Dutch parliament between 1945-1995 to over 1.5 million newspaper articles, while Talk of Europe publishes the entire plenary debates of the European Parliament as linked open data consisting of over 14 million RDF statements about speeches between 1999-2014. Both projects model the data as structured events that can be queried to enable complex analysis across sources and time spans.

This document provides a step-by-step demo scenario for an online news application that allows users to explore topics in newspaper articles, how frequently topics are mentioned, which topics co-occur, and images selected for articles. The application allows side-by-side comparison of topics between two newspapers or topics. Users can select a newspaper, choose a topic, and select topics, categories or image concepts to explore, seeing which topics frequently appear with the selected topic. Charts also allow selecting articles to view. The document demonstrates comparing coverage of Bernie Sanders between the New York Times and Washington Post.
Talk of Europe: Linked data of the European ParliamentLaura Hollink
The document summarizes the Talk of Europe project, which publishes data from proceedings of the European Parliament as linked open data. It includes over 14 million triples about 30,000 speeches given over 15 years. The data is made available through a SPARQL endpoint and can be used to analyze topics discussed, differences between members and parties, and other insights. Creative camps are held for people to work with the data.

Dandelion Hashtable: beyond billion requests per second on a commodity serverAntonios Katsarakis
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).
How information systems are built or acquired puts information, which is what they should be about, in a secondary place. Our language adapted accordingly, and we no longer talk about information systems but applications. Applications evolved in a way to break data into diverse fragments, tightly coupled with applications and expensive to integrate. The result is technical debt, which is re-paid by taking even bigger "loans", resulting in an ever-increasing technical debt. Software engineering and procurement practices work in sync with market forces to maintain this trend. This talk demonstrates how natural this situation is. The question is: can something be done to reverse the trend?

"NATO Hackathon Winner: AI-Powered Drug Search", Taras KlobaFwdays
This is a session that details how PostgreSQL's features and Azure AI Services can be effectively used to significantly enhance the search functionality in any application.
In this session, we'll share insights on how we used PostgreSQL to facilitate precise searches across multiple fields in our mobile application. The techniques include using LIKE and ILIKE operators and integrating a trigram-based search to handle potential misspellings, thereby increasing the search accuracy.
We'll also discuss how the azure_ai extension on PostgreSQL databases in Azure and Azure AI Services were utilized to create vectors from user input, a feature beneficial when users wish to find specific items based on text prompts. While our application's case study involves a drug search, the techniques and principles shared in this session can be adapted to improve search functionality in a wide range of applications. Join us to learn how PostgreSQL and Azure AI can be harnessed to enhance your application's search capability.

QR Secure: A Hybrid Approach Using Machine Learning and Security Validation F...AlexanderRichford
QR Secure: A Hybrid Approach Using Machine Learning and Security Validation Functions to Prevent Interaction with Malicious QR Codes.
Aim of the Study: The goal of this research was to develop a robust hybrid approach for identifying malicious and insecure URLs derived from QR codes, ensuring safe interactions.
This is achieved through:
Machine Learning Model: Predicts the likelihood of a URL being malicious.
Security Validation Functions: Ensures the derived URL has a valid certificate and proper URL format.
This innovative blend of technology aims to enhance cybersecurity measures and protect users from potential threats hidden within QR codes 🖥 🔒
This study was my first introduction to using ML which has shown me the immense potential of ML in creating more secure digital environments!
From Natural Language to Structured Solr Queries using LLMsSease
This talk draws on experimentation to enable AI applications with Solr. One important use case is to use AI for better accessibility and discoverability of the data: while User eXperience techniques, lexical search improvements, and data harmonization can take organizations to a good level of accessibility, a structural (or “cognitive” gap) remains between the data user needs and the data producer constraints.
That is where AI – and most importantly, Natural Language Processing and Large Language Model techniques – could make a difference. This natural language, conversational engine could facilitate access and usage of the data leveraging the semantics of any data source.
The objective of the presentation is to propose a technical approach and a way forward to achieve this goal.
The key concept is to enable users to express their search queries in natural language, which the LLM then enriches, interprets, and translates into structured queries based on the Solr index’s metadata.
This approach leverages the LLM’s ability to understand the nuances of natural language and the structure of documents within Apache Solr.
The LLM acts as an intermediary agent, offering a transparent experience to users automatically and potentially uncovering relevant documents that conventional search methods might overlook. The presentation will include the results of this experimental work, lessons learned, best practices, and the scope of future work that should improve the approach and make it production-ready.

In response to the urgency and scale required to effectively address climate change, open source solutions offer significant potential for driving innovation and progress. Currently, there is a growing demand for standardization and interoperability in energy data and modeling. Open source standards and specifications within the energy sector can also alleviate challenges associated with data fragmentation, transparency, and accessibility. At the same time, it is crucial to consider privacy and security concerns throughout the development of open source platforms.
This webinar will delve into the motivations behind establishing LF Energy’s Carbon Data Specification Consortium. It will provide an overview of the draft specifications and the ongoing progress made by the respective working groups.
Three primary specifications will be discussed:
-Discovery and client registration, emphasizing transparent processes and secure and private access
-Customer data, centering around customer tariffs, bills, energy usage, and full consumption disclosure
-Power systems data, focusing on grid data, inclusive of transmission and distribution networks, generation, intergrid power flows, and market settlement data
