The document discusses RDFa, which allows adding semantic annotations to web documents. RDFa uses additional attributes to embed RDF triples directly in HTML/XHTML pages. This enables computers to extract structured data from the documents. Examples shown include annotating a person's name, address, an image's title and creator, and embedding a Creative Commons license. RDFa triples follow the form of a subject, property and object, reusing terms from vocabularies like FOAF and Dublin Core.

SPARQL and the Open Linked Data initiative
An introduction to the SPARQL query language and its application to the Open Linked Data initiative. Slides for the PhD Course on Semantic Web (http://elite.polito.it/).
Aall denver 2010
The document discusses moving away from traditional library data models based on catalog records towards a model using semantic web standards. It envisions describing resources with statements about properties and values linked by URIs, rather than constrained data elements within records. This allows for more flexible aggregation of descriptive data from various sources to describe resources in different ways. An example shows how bibliographic data could be broken into simple statements that could then be reassembled in various meaningful descriptions.
Data in RDF
The document discusses representing data in the Resource Description Framework (RDF). It describes how relational data can be represented as RDF triples with rows becoming subjects, columns becoming properties, and values becoming objects. It also discusses using URIs instead of internal IDs and names to allow data integration. The document then covers serializing RDF data in different formats like RDF/XML, N-Triples, N3, and Turtle and describes syntax for representing literals, language tags, and abbreviating subject and predicate pairs.
when the link makes sense
The document discusses the Semantic Web and linked data. It describes standards like RDF, RDFS, and OWL that add structure and meaning to data on the web. Triples are used to represent information that can then be queried or linked to other data to form a global graph. The principles of linked data encourage using URIs, HTTP, and content negotiation to publish and interconnect structured data on the web.
Rdf In A Nutshell V1
RDF is a framework for describing resources on the web using triples of the form (subject, predicate, object). It allows metadata to be added to resources, enabling applications to publish and link open data on the web. RDF descriptions can be seen as a graph with resources as nodes and properties as edges between them. RDF has XML and other syntaxes and provides primitives for building containers, collections, and structured values.
Name That Graph !
This document discusses the need for named graphs in RDF to represent contextual information like provenance and source of RDF data. It proposes extensions to the RDF/XML syntax to associate RDF descriptions and statements with named graphs. This allows modeling things like different hypotheses, temporal aspects, points of view, and distributed storage in a way that is currently not possible without named graphs in the RDF model.

John Fagan: The Black Art of Geocoding
Geocoding is more difficult than mapping and routing due to challenges with parsing unstructured address inputs and inconsistencies in reference data. Parsing addresses requires probabilistic approaches like hidden Markov models to understand varied address formats. Reference databases are complicated by issues like multiple valid address names and changing street names. While mapping and routing rely on established algorithms and standardized data, geocoding requires continuously trying to improve parsing techniques and enriching reference data with historical records to better match unpredictable real world addresses.
MULDER: Querying the Linked Data Web by Bridging RDF Molecule Templates
The increasing number of RDF data sources that allow for
querying Linked Data via Web services form the basis for federated SPARQL query processing. Federated SPARQL query engines provide a unified view of a federation of RDF data sources, and rely on source descriptions for selecting the data sources over which unified queries will be executed. Albeit efficient, existing federated SPARQL query engines usually ignore the meaning of data accessible from a data source,
and describe sources only in terms of the vocabularies utilized in the data source. Lack of source description may conduce to the erroneous selection of data sources for a query, thus affecting the performance of query processing over the federation. We tackle the problem of federated SPARQL query processing and devise MULDER, a query engine for federations of RDF data sources. MULDER describes data sources in terms of RDF molecule templates, i.e., abstract descriptions of entities
belonging to the same RDF class. Moreover, MULDER utilizes RDF molecule templates for source selection, and query decomposition and optimization. We empirically study the performance of MULDER on existing benchmarks, and compare MULDER performance with state-of-the-art federated SPARQL query engines. Experimental results suggest that RDF molecule templates empower MULDER federated query processing, and allow for the selection of RDF data sources that not only reduce execution time, but also increase answer completeness.

The lecture covers:
Part I: Querying RDF(S P O) tables using SQL
Part 2: Practical Session (RDF graphs )
Part 3: SQL-based RDF Stores
Searching
Depth-first search (DFS) is a graph search algorithm that explores all nodes that are reachable from the starting node by traversing edges in a depth-first manner. It uses a stack to remember to explore the neighbor of the current node before backtracking. The algorithm marks nodes as visited as it traverses the graph and can detect cycles.
Introduction to RDF
The document discusses the Semantic Web and Resource Description Framework (RDF). It defines the Semantic Web as making web data machine-understandable by describing web resources with metadata. RDF uses triples to describe resources, properties, and relationships. RDF data can be visualized as a graph and serialized in formats like RDF/XML. RDF Schema (RDFS) provides a basic vocabulary for defining classes, properties, and hierarchies to enable reasoning about RDF data.
Search engines coh m
Search engines are programs that search documents for keywords and return a list of documents containing those keywords. Examples include Google and Yahoo. They work by using web crawlers to locate documents and indexers to create indexes of words in each document. Google provides many useful search features beyond basic keyword searches, including calculators, unit converters, clocks for different time zones, weather and flight status checks, and more specialized searches like site: searches. The document provides examples of how to use advanced search features on Google to refine searches by file format, domain, keyword locations, and excluding certain words.

Federated Query Formulation and Processing through BioFed
A single interface for accessing life sciences (LS) data is a natural consequence to master the data deluge in this domain. The data in the LS requires integration and current integrative solutions increasingly rely on the federation of queries for distributed resources. We introduce a federated query processing system name ``BioFed", customised for LS-LOD. BioFed federates SPARQL queries over more than 130 public SPARQL endpoints.
HiBISCuS: Hypergraph-Based Source Selection for SPARQL Endpoint Federation
Efficient federated query processing is of significant importance to tame the large amount of data available on the Web of Data. Previous works have focused on generating optimized query execution plans for fast result retrieval. However, devising source selection approaches beyond triple pattern-wise source selection has not received much attention. This work presents HiBISCuS, a novel hypergraph-based source selection approach to federated SPARQL querying. Our approach can be directly combined with existing SPARQL query federation engines to achieve the same recall while querying fewer data sources. We extend three well-known SPARQL query federation engines with HiBISCus and compare our extensions with the original approaches on FedBench. Our evaluation shows that HiBISCuS can efficiently reduce the total number of sources selected without losing recall. Moreover, our approach significantly reduces the execution time of the selected engines on most of the benchmark queries.
Note Taking Data Chart 6th
The document provides instructions for creating a data chart to organize information from sources for a final project.

Creating Linked Data 2/5 Semtech2011
This document discusses Linked Data and the best practices for publishing and interlinking data on the web. It covers four main principles:
1) Use URIs as names for things and identify real-world objects with HTTP URIs.
2) Use HTTP URIs so that people can look up those names by dereferencing the URIs.
3) Provide useful RDF information when URIs are dereferenced, using formats like RDF/XML, RDFa, N3, or Turtle.
4) Include links to other URIs to discover more related things and connect isolated data silos. This allows data to be interlinked on the Web.
Semantic Web And Coldfusion
The Semantic Web is the extension of the World Wide Web that enables people to share content beyond the boundaries of applications and websites.
It has been described in rather different ways: as a utopic vision, as a web of data, or merely as a natural paradigm shift in our daily use of the Web.
Most of all, the Semantic Web has inspired and engaged many people to create innovative and intelligent technologies and applications.
In this presentation we describe the underlying principles and key features of the semantic web along with where and how they fit in with server side and client side technologies supported by ColdFusion.
Semantic Web
The document provides an overview of the semantic web including its goals of making data meaningful and discoverable. It discusses approaches to building the semantic web such as RDF, RDFS, OWL, and SPARQL. It also covers microformats as a more practical approach and provides examples of using RDF, OWL, SPARQL, and various microformats.
"RDFa - what, why and how?" by Mike Hewett and Shamod Lacoul
The document discusses RDFa (Resource Description Framework in Attributes), which allows adding semantic metadata to web pages. It provides an overview of RDFa and examples of using RDFa to annotate events, people, and other entities on web pages in order to make the information machine-readable. The examples demonstrate how RDFa can be used to embed semantics in HTML and reuse attributes, allowing the HTML and RDF data to coexist in the same document.
Exploiter le Web Semantic, le comprendre et y contribuer
The document discusses using Watson, a gateway to the Semantic Web, to both develop applications that exploit online semantic resources and to better understand the Semantic Web.

It also explains how Watson has been used as a research platform to characterize ontologies in its collection, understand relations between ontologies, and measure agreement between statements and ontologies.
DC-2008 Tutorial 3 - Dublin Core and other metadata schemas
The document discusses metadata standards and interoperability. It provides an overview of Dublin Core and other metadata schemas. It describes how Dublin Core terms are defined both for human understanding through textual definitions, as well as machine understanding through formal semantics expressed in RDF. This allows metadata using Dublin Core terms to be combined and processed in an interoperable way on the Semantic Web.
Sem webmaubeuge
The document introduces the Semantic Web and the key technologies that enable it, including RDF, RDF Schema, OWL, and SPARQL. RDF allows for describing resources and relationships between them using triples. RDF Schema extends RDF with a vocabulary for describing properties and classes of resources. OWL builds on RDF and RDF Schema to provide additional expressive power for defining complex ontologies. SPARQL is a query language for retrieving and manipulating data stored in RDF format. These technologies work together to transform the existing web of documents into a web of linked data that can be processed automatically by machines.
RDFa: The Semantic Web's Missing Link
This presentation was given at SemTech 2009.
RDFa combines the power of RDF with the ease of publishing of HTML, making it the missing link of the semantic web. Now anyone who is able to publish to the web -- from bloggers, to corporates to governments -- can easily publish to the semantic web.
This session will introduce the key ideas of RDFa and its syntax, by way of a case-study of a project from a UK government department. We'll also survey the state of support in tools and software.

In 2012 it launched its first data portal and by 2013 had made open data part of its regular operations. It launched a new city website in 2014 and began publishing linked open data in 2016. It provides examples of SPARQL queries that can be used against the linked open data and discusses next steps of increasing internal knowledge, using linked data internally, publishing additional leisure data, and collaborating with other governments on ontologies.

Rule-based Modeling of Mashups
Rule-based mashups can be implemented both server-side and client-side using rules to orchestrate various services. Rules define widget dependencies and user interactions to customize the mashup experience. Client-side mashups allow users to interact directly with services using local rules without relying on a dedicated mashup server.
Mashups and Web Services
The document discusses mashups, which combine data or applications from multiple sources to create new functionality. It defines server-side mashups as applications built by programmers that orchestrate web services, while client-side mashups allow end users to mix services through widgets. The document argues that most modern applications can be considered early forms of mashups, and that Representational State Transfer (REST) is commonly used to access data feeds that power mashups.
Building Intelligent Mashups
The document discusses building intelligent mashups using artificial intelligence techniques. It proposes using JSON-based rules that can be run in a browser-based rules engine to combine data from different web sources and applications. This would allow non-programmers to more easily create intelligent mashups by specifying event-condition-action rules without advanced coding skills. Open challenges discussed include a lack of widget standards and potential security and performance issues.
Mashups as Collection of Widgets
1. Mashups are collections of small applications called widgets that can be embedded into web pages using standards like XML, HTML, JavaScript and CSS.
2. Major companies develop their own widget platforms with tools to create and deploy widgets, such as Google Gadgets, Yahoo Widgets and Amazon Widgets.
3. Widgets are described in XML files but require a widget engine for execution, making their implementation dependent on the hosting platform. Standardization efforts are ongoing but adoption by providers is uncertain.
Introduction to visual rules modeling
This document discusses modeling rules using visual languages. It introduces vocabularies to represent concepts like customers and shopping carts. Rules are presented using if-then syntax to describe discounts based on customer type. UML class diagrams and RDFS/OWL are compared for representing vocabularies. Rules should be modeled to avoid ambiguity, and rule languages like Drools are suggested for encoding rules formally. The document asks questions to check the reader's knowledge of rule modeling and applications.
Introduction to Rule-based Applications
This document provides an introduction to rule-based applications from Adrian Giurca of eBusiness Technologies. It discusses how rules are well-suited for applications with dynamic business logic that needs to change frequently. Examples of rule-based domains include insurance, financial services, government, telecom and e-commerce. It also introduces Drools, an open-source Java-based rule engine, and how rules can be modeled with UML and expressed in both logic programming and Drools rule language syntax.
Intelligent Mashups
An intelligent mashup uses artificial intelligence techniques like rule-based reasoning to combine web services and applications. This allows implementing functionality like delivering similar news to a user who reads about swine flu. Rule-based mashups can be done client-side in the browser using event-condition-action rules to derive knowledge from user activity. Benefits include easy modeling of relationships, intelligent user interfaces, and reduced network traffic through local reasoning, while drawbacks include needing skilled developers for server-side options and consuming client resources.
JSON Rules Language
The document discusses JSON Rules, a rule language for the web browser:
1. JSON Rules allows defining event-condition-action rules that can run in the browser and address information on web pages.
2. Rules are represented using JSON notation for compatibility with JavaScript. Events can be DOM events or custom events, conditions can use JavaScript, XPath, or built-in predicates, and actions can be any JavaScript function call.
3. The document outlines the goals and requirements of JSON Rules, provides examples of rule syntax including events, conditions, and actions, and proposes a roadmap for the development of a JSON Rules engine and its applications.
Introduction to Drools
This document provides an introduction to Drools, an open source Java-based rule engine. It discusses embedding rules in applications, designing rule-based applications based on existing domain vocabularies, and the basic structure and components of rulesets in Drools, including imports, globals, functions, and the condition and action parts of rules. It also covers more advanced pattern types such as "from" and "accumulate" that allow reasoning over data from other sources.
Semantic Pipes and Semantic Mashups
Semantic pipes aggregate data from multiple sources to create new data sources, similar to Yahoo! Pipes. Semantic pipes operate on RDF data sources using SPARQL queries. DERI Pipes is a tool for building semantic pipes that defines blocks for processing RDF and other data sources. Semantic mashups may have additional reasoning capabilities beyond basic data aggregation, using semantic web reasoners. They implement behavior through SPARQL queries over RDF data. Examples include mashups over Flickr, book data, and scholarly references.
