This document discusses enriching affiliation networks in SKOS-based datasets. It proposes a tripartite model representing users annotating resources with tags linked by SKOS broader/narrower properties. This model can be represented as graphs like an actors graph obtained from a dataset with authors, publications and MeSH concepts. Broader semantic relations between tags allow identifying patterns like parent-child and sibling relations. The approach aims to enhance information discovery and help connect users based on emerging relations between topics.

Presentation at the "Reasoning from experiences on the Web" workshop (WebCBR 2010) at the International Conference on Case Based Reasoning 2010. Abstract: While Case-based reasoning (CBR) has successfully been deployed on the Web, its data models are typically inconsistent with existing information infrastructure and standards. In this paper, we examine how CBR can operate on the emerging Web of Data, with mutual benefits. The expense of knowledge engineering and curating a case base can be reduced by using Linked Data from the Web of Data. While Linked Data provides experiential data from many different domains, it also contains inconsistencies, missing data and noise which provide challenges for logic-based reasoning. CBR is well suited to provide alternative and robust reasoning approaches. We introduce (i) a lightweight CBR vocabulary which is suited for the open ecosystem of the emerging Web of Data, and provide (ii) a detailed example of a case base using data from multiple sources. We propose that for the ﬁrst time the Web of Data provides data and a real context for open CBR systems.

Lessons and requirements from a decade of deployed Semantic Web appsBenjamin Heitmann

The document summarizes lessons learned from analyzing over 100 Semantic Web applications from challenge competitions over the past decade. It finds that while standards like RDF, OWL and SPARQL are widely used, there remain gaps in publishing and updating Linked Data. Most applications require human intervention for data integration due to noisy RDF data. There is also a mismatch between graph-based data models and relational/object-oriented components. The document recommends addressing these issues through more guidelines, libraries, and software frameworks to improve the software engineering process for building Semantic Web applications.

An architecture for privacy-enabled user profile portability on the Web of DataBenjamin Heitmann

Presentation at the Heterogeneous Recommendation Workshop at the ACM Recommender Systems Conference 2010. Providing relevant recommendations requires access to user profile data. Current social networking ecosystems allow third party services to request user authorisation for accessing profile data, thus enabling cross-domain recommendation. However these ecosystems create user lock-in and social networking data silos, as the profile data is neither portable nor interoperable. We argue that innovations in reconciling heterogeneous data sources must be also be matched by innovations in architecture design and recommender methodology. We present and qualitatively evaluate an architecture for privacy-enabled user profile portability, which is based on technologies from the emerging Web of Data (FOAF, WebIDs and the Web Access Control vocabulary). The proposed architecture enables the creation of a universal “private by default” ecosystem with interoperability of user profile data. The privacy of the user is protected by allowing multiple data providers to host their part of the user profile. This provides an incentive for more users to make profile data from different domains available for recommendations.

Taming digital traces for informal learning dhavalDhavalkumar Thakker

Modern learning models require linking experiences in training environments with experiences in the real-world. However, data about real-world experiences is notoriously hard to collect. Social spaces bring new opportunities to tackle this challenge, supplying digital traces where people talk about their real-world experiences. These traces can become valuable resource, especially in ill-defined domains that embed multiple interpretations. The paper presents a unique approach to aggregate content from social spaces into a semantic-enriched data browser to facilitate informal learning in ill-defined domains. This work pioneers a new way to exploit digital traces about real-world experiences as authentic examples in informal learning contexts. An exploratory study is used to determine both strengths and areas needing attention. The results suggest that semantics can be successfully used in social spaces for informal learning – especially when combined with carefully designed nudges.

The Web of Data - Tom Heathsssw2012

The document discusses the Web of Data, which is a boundless graph of interconnected data available online. It describes how the Web of Data differs from just having data on the web by having links between related data points. This allows the data to have more structure and meaning. The basic building blocks that make up the Web of Data are Resource Description Framework (RDF) triples that express relationships between subjects and objects. By using HTTP URIs to identify things and RDF to express relationships, the Web of Data aims to make data on the web more connected and meaningful.

The document discusses semantic systems and how they can help solve problems related to integrating different types of systems by facilitating interoperability. It outlines some of the key challenges, such as the lack of tools that are easy for average users while also being powerful enough for experts. The document also discusses different semantic technologies like ontologies, logic programming, and the Semantic Web that could help address these challenges if implemented properly with a focus on integration rather than fragmentation.

Knowledge management on the desktopLaura Dragan

This document discusses the history and modern approaches to knowledge management systems on the desktop. It traces ideas back to Vannevar Bush's 1945 proposal of the memex device. More recent systems like Doug Engelbart's NLS in the 1960s and Ted Nelson's Xanadu aimed to improve linking and navigation of information. Modern semantic desktops take a layered, modular approach and use ontologies and semantic technologies to unlock and integrate desktop data. They provide services like storage, extraction, annotation and inference to enhance existing applications and help users manage information overload. Evaluation of these systems remains a challenge due to their personal, customized nature.

This document discusses k-means clustering and different initialization methods. K-means clustering partitions objects into k clusters based on their attributes, with objects in the same cluster being similar and objects in different clusters being dissimilar. The initialization method affects the clustering result and number of iterations, with better initialization methods leading to fewer iterations. The document compares random, Forgy, MacQueen, and Kaufman initialization methods.

K-means Clustering with Scikit-LearnSarah Guido

Given at PyDataSV 2014 In machine learning, clustering is a good way to explore your data and pull out patterns and relationships. Scikit-learn has some great clustering functionality, including the k-means clustering algorithm, which is among the easiest to understand. Let's take an in-depth look at k-means clustering and how to use it. This mini-tutorial/talk will cover what sort of problems k-means clustering is good at solving, how the algorithm works, how to choose k, how to tune the algorithm's parameters, and how to implement it on a set of data.

K means ClusteringEdureka!

The document discusses clustering and k-means clustering algorithms. It provides examples of scenarios where clustering can be used, such as placing cell phone towers or opening new offices. It then defines clustering as organizing data into groups where objects within each group are similar to each other and dissimilar to objects in other groups. The document proceeds to explain k-means clustering, including the process of initializing cluster centers, assigning data points to the closest center, recomputing the centers, and iterating until centers converge. It provides a use case of using k-means to determine locations for new schools.

K means Clustering AlgorithmKasun Ranga Wijeweera

K-means clustering is an algorithm that groups data points into k number of clusters based on their similarity. It works by randomly selecting k data points as initial cluster centroids and then assigning each remaining point to the closest centroid. It then recalculates the centroids and reassigns points in an iterative process until centroids stabilize. While efficient, k-means clustering has weaknesses in that it requires specifying k, can get stuck in local optima, and is not suitable for non-convex shaped clusters or noisy data.

This document discusses challenges with current bookmarking systems and proposes an enhanced bookmark called "Webmark" to address them. It notes that the web has evolved rapidly in a technology-driven way without clear definitions, making it difficult to design tools to help users orient themselves. It also observes that web references are unreliable due to dynamic content, URLs becoming obsolete, and the page-based model being insufficient. The document then hypothesizes that modeling web objects and reference types from a user perspective could help with orientation solutions, and proposes defining web pages as information mediums that interact rather than documents or memory extensions. It outlines different types of intentions in marking web resources and envisions Webmark providing dedicated services based on the marking kind.

It describes requirements for SSIS including semantics for modeling community structures and interactions. SSIS can improve search, integration and reuse of user-generated content within enterprise environments. The document outlines various implementations of SSIS including semantic wikis, tagging and interlinking spaces. Developing common vocabularies and interlinking SSIS across different domains can help create a more interlinked online information society.

A distributional structured semantic space for querying rdf graph dataAndre Freitas

The vision of creating a Linked Data Web brings together the challenge of allowing queries across highly heterogeneous and distributed datasets. In order to query Linked Data on the Web today, end users need to be aware of which datasets potentially contain the data and also which data model describes these datasets. The process of allowing users to expressively query relationships in RDF while abstracting them from the underlying data model represents a fundamental problem for Web-scale Linked Data consumption. This article introduces a distributional structured semantic space which enables data model independent natural language queries over RDF data. The center of the approach relies on the use of a distributional semantic model to address the level of semantic interpretation demanded to build the data model independent approach. The article analyzes the geometric aspects of the proposed space, providing its description as a distributional structured vector space, which is built upon the Generalized Vector Space Model (GVSM). The final semantic space proved to be flexible and precise under real-world query conditions achieving mean reciprocal rank = 0.516, avg. precision = 0.482 and avg. recall = 0.491.

Linked data principles and exporting data in RDF/FOAF from platforms helps to unify user identities and network across platforms addressing current issues.

Challenges Ahead for Converging Financial DataEdward Curry

Consumers of financial information come in many guises from personal investors looking for that value for money share, to government regulators investigating corporate fraud, to business executives seeking competitive advantage over their competition. While the particular analysis performed by each of these information consumers will vary, they all have to deal with the explosion of information available from multiple sources including, SEC filings, corporate press releases, market press coverage, and expert commentary. Recent economic events have begun to bring sharp focus on the activities and actions of financial markets, institutions and not least regulatory authorities. Calls for enhanced scrutiny will bring increased regulation and information transparency While extracting information from individual filings is relatively easy to perform when a machine readable format is utilized (for example, using XBRL, the eXtensible Business Reporting Language), cross comparison of extracted financial information can be problematic as descriptions and accounting terms vary across companies and jurisdictions. Across multiple sources the problem becomes the classical data integration problem where a common data abstraction is necessary before functional data use can begin. Within this paper we discuss the challenges in converging financial data from multiple sources. We concentrate on integrating data from multiple sources in terms of the abstraction, linking, and consolidation activities needed to consolidate data before more sophisticated analysis algorithms can examine the data for the objectives of particular information consumers (for e.g. competitive analysis, regulatory compliance, or investor analysis). We base our discussion on several years researching and deploying data integration systems in both the web and enterprise environments. E. Curry, A. Harth, and S.

A new direction for recommender systems: balancing privacy and personalisationBenjamin Heitmann

In this talk, Benjamin Heitmann will introduce a new direction for future recommender systems: the idea of balancing privacy and personalisation when designing a personalisation approach. First, recent events which form the motivation for this new direction are introduced, then the basics of current personalisation approaches and how they approach data collection are presented. After that, several different aspects of balancing privacy and personalisation are discussed, which will show that this is a wide open topic for research and innovation.

Benjamin Heitmann, PhD defence talk: An Open Framework for Multi-source, Cro...Benjamin Heitmann

The work in this thesis addresses the new challenges and opportunities for online personalisation posed by the emergence of new infrastructures for sharing user preferences and for access to open repositories of data. As a result of these new infrastructures, user profiles can now include data from multiple sources about preferences in multiple domains. This new kind of user profile data requires a cross-domain personalisation approach. However, current cross-domain personalisation approaches are restricted to proprietary social networking ecosystems. The main problem that we address in this thesis, is to enable cross-domain recommendations without the use of proprietary and closed infrastructure. Towards this goal, we propose an open framework for cross-domain personalisation. Our framework consists of two parts: a conceptual architecture for recommender systems, and our cross-domain personalisation approach. The main enabling technology for our framework is Linked Open Data, as it provides a common data presentation for user preferences and cross-domain links between concepts from many different domains. As part of our framework, we first propose a conceptual architecture for Linked Open Data recommender systems that provides guidelines and best practices for the typical high level components required for providing personalisation in open ecosystems using Linked Open Data. The architecture has a strong empirical founding, as it based on an empirical survey of 124 RDF-based applications. Then we introduce and throughly evaluate SemStim, an unsupervised, graph-based algorithm for cross-domain personalisation. It leverages multi-source, domain-neutral user profiles and the semantic network of DBpedia in order to generate recommendations for different source and target domains. The results of our evaluation show that SemStim is able to provide cross-domain recommendations, without any overlap between target and source domains and without using any ratings in the target domain. We show how we instantiate our proposed conceptual architecture for a prototype implementation that is the outcome of the ADVANSSE collaboration project with CISCO Galway. The prototype shows how to implement our framework for a real-world use case and data. Our open framework for cross-domain personalisation provides an alternative to existing proprietary cross-domain personalisation approaches. As such, it opens up the potential for novel and innovative personalised services without the risk of user lock-in and data silos.

YSPH VMOC Special Report - Measles Outbreak Southwest US 5-3-2025.pptxYale School of Public Health - The Virtual Medical Operations Center (VMOC)

A measles outbreak originating in West Texas has been linked to confirmed cases in New Mexico, with additional cases reported in Oklahoma and Kansas. The current case count is 817 from Texas, New Mexico, Oklahoma, and Kansas. 97 individuals have required hospitalization, and 3 deaths, 2 children in Texas and one adult in New Mexico. These fatalities mark the first measles-related deaths in the United States since 2015 and the first pediatric measles death since 2003. The YSPH Virtual Medical Operations Center Briefs (VMOC) were created as a service-learning project by faculty and graduate students at the Yale School of Public Health in response to the 2010 Haiti Earthquake. Each year, the VMOC Briefs are produced by students enrolled in Environmental Health Science Course 581 - Public Health Emergencies: Disaster Planning and Response. These briefs compile diverse information sources – including status reports, maps, news articles, and web content– into a single, easily digestible document that can be widely shared and used interactively. Key features of this report include: - Comprehensive Overview: Provides situation updates, maps, relevant news, and web resources. - Accessibility: Designed for easy reading, wide distribution, and interactive use. - Collaboration: The “unlocked" format enables other responders to share, copy, and adapt seamlessly. The students learn by doing, quickly discovering how and where to find critical information and presenting it in an easily understood manner. CURRENT CASE COUNT: 817 (As of 05/3/2025) • Texas: 688 (+20)(62% of these cases are in Gaines County). • New Mexico: 67 (+1 )(92.4% of the cases are from Eddy County) • Oklahoma: 16 (+1) • Kansas: 46 (32% of the cases are from Gray County) HOSPITALIZATIONS: 97 (+2) • Texas: 89 (+2) - This is 13.02% of all TX cases. • New Mexico: 7 - This is 10.6% of all NM cases. • Kansas: 1 - This is 2.7% of all KS cases.

To study the nervous system of insect.pptxArshad Shaikh

The *nervous system of insects* is a complex network of nerve cells (neurons) and supporting cells that process and transmit information. Here's an overview: Structure 1. *Brain*: The insect brain is a complex structure that processes sensory information, controls behavior, and integrates information. 2. *Ventral nerve cord*: A chain of ganglia (nerve clusters) that runs along the insect's body, controlling movement and sensory processing. 3. *Peripheral nervous system*: Nerves that connect the central nervous system to sensory organs and muscles. Functions 1. *Sensory processing*: Insects can detect and respond to various stimuli, such as light, sound, touch, taste, and smell. 2. *Motor control*: The nervous system controls movement, including walking, flying, and feeding. 3. *Behavioral responThe *nervous system of insects* is a complex network of nerve cells (neurons) and supporting cells that process and transmit information.

APM Midlands Region April 2025 Sacha Hind Circulated.pdfAssociation for Project Management

APM event hosted by the Midlands Network on 30 April 2025. Speaker: Sacha Hind, Senior Programme Manager, Network Rail With fierce competition in today’s job market, candidates need a lot more than a good CV and interview skills to stand out from the crowd. Based on her own experience of progressing to a senior project role and leading a team of 35 project professionals, Sacha shared not just how to land that dream role, but how to be successful in it and most importantly, how to enjoy it! Sacha included her top tips for aspiring leaders – the things you really need to know but people rarely tell you! We also celebrated our Midlands Regional Network Awards 2025, and presenting the award for Midlands Student of the Year 2025. This session provided the opportunity for personal reflection on areas attendees are currently focussing on in order to be successful versus what really makes a difference. Sacha answered some common questions about what it takes to thrive at a senior level in a fast-paced project environment: Do I need a degree? How do I balance work with family and life outside of work? How do I get leadership experience before I become a line manager? The session was full of practical takeaways and the audience also had the opportunity to get their questions answered on the evening with a live Q&A session. Attendees hopefully came away feeling more confident, motivated and empowered to progress their careers

CBSE - Grade 8 - Science - Chemistry - Metals and Non Metals - WorksheetSritoma Majumder

Introduction All the materials around us are made up of elements. These elements can be broadly divided into two major groups: Metals Non-Metals Each group has its own unique physical and chemical properties. Let's understand them one by one. Physical Properties 1. Appearance Metals: Shiny (lustrous). Example: gold, silver, copper. Non-metals: Dull appearance (except iodine, which is shiny). 2. Hardness Metals: Generally hard. Example: iron. Non-metals: Usually soft (except diamond, a form of carbon, which is very hard). 3. State Metals: Mostly solids at room temperature (except mercury, which is a liquid). Non-metals: Can be solids, liquids, or gases. Example: oxygen (gas), bromine (liquid), sulphur (solid). 4. Malleability Metals: Can be hammered into thin sheets (malleable). Non-metals: Not malleable. They break when hammered (brittle). 5. Ductility Metals: Can be drawn into wires (ductile). Non-metals: Not ductile. 6. Conductivity Metals: Good conductors of heat and electricity. Non-metals: Poor conductors (except graphite, which is a good conductor). 7. Sonorous Nature Metals: Produce a ringing sound when struck. Non-metals: Do not produce sound. Chemical Properties 1. Reaction with Oxygen Metals react with oxygen to form metal oxides. These metal oxides are usually basic. Non-metals react with oxygen to form non-metallic oxides. These oxides are usually acidic. 2. Reaction with Water Metals: Some react vigorously (e.g., sodium). Some react slowly (e.g., iron). Some do not react at all (e.g., gold, silver). Non-metals: Generally do not react with water. 3. Reaction with Acids Metals react with acids to produce salt and hydrogen gas. Non-metals: Do not react with acids. 4. Reaction with Bases Some non-metals react with bases to form salts, but this is rare. Metals generally do not react with bases directly (except amphoteric metals like aluminum and zinc). Displacement Reaction More reactive metals can displace less reactive metals from their salt solutions. Uses of Metals Iron: Making machines, tools, and buildings. Aluminum: Used in aircraft, utensils. Copper: Electrical wires. Gold and Silver: Jewelry. Zinc: Coating iron to prevent rusting (galvanization). Uses of Non-Metals Oxygen: Breathing. Nitrogen: Fertilizers. Chlorine: Water purification. Carbon: Fuel (coal), steel-making (coke). Iodine: Medicines. Alloys An alloy is a mixture of metals or a metal with a non-metal. Alloys have improved properties like strength, resistance to rusting.
