The Semantic Web grows constantly and promises a huge amount of machine-interpretable information. Unfortunately, the inte- gration and usage of semantic information is not feasible by everyone. Hence, a large number of Semantic Web applications are lacking and the potential of the semantic knowledge remains unexploited. We propose balloon Synopsis, an easy-to-use jQuery plugin to integrate Semantic Web information in a website. It provides a modern visualisation and browser for RDF information including automatic remote information enhancing, similarity analysis and ontology templates. Balloon Synopsis enables web developers to rely on known tools and programming lan- guage to benefit of the global knowledge graph.

The Web of data and web data commons
An introduction deck for the Web of Data to my team, including basic semantic web, Linked Open Data, primer, and then DBpedia, Linked Data Integration Framework (LDIF), Common Crawl Database, Web Data Commons.
Web scraping
Web scraping involves extracting data from human-readable web pages and converting it into structured data. There are several types of scraping including screen scraping, report mining, and web scraping. The process of web scraping typically involves using techniques like text pattern matching, HTML parsing, and DOM parsing to extract the desired data from web pages in an automated way. Common tools used for web scraping include Selenium, Import.io, Phantom.js, and Scrapy.
Linked data-tooling-xml
This document discusses how linked data and XML can be integrated using tools like XSLT and Apache Jena. It provides examples of converting an XML table and XLIFF file to the Turtle format. Methods for querying linked data via SPARQL from within XSLT are also presented.
EC-WEB: Validator and Preview for the JobPosting Data Model of Schema.org
The presentation describes a tool for validating and previewing instances of Schema.org JobPosting described in structured data markup embedded in web pages. The validator and preview was developed to assist users of Schema.org to produce data of better quality. In this way, it tries to enhance usability of a part of Schema.org covering the domain of job postings. The paper discusses implementation of the tool and design of its validation rules based on SPARQL 1.1. Results of experimental validation of a job posting corpus harvested from the Web are presented. Among other findings, the results indicate that publishers of Schema.org JobPosting data often misunderstand precedence rules employed by markup parsers and that they ignore case-sensitivity of vocabulary names.
Linked data tooling XML
The document discusses linking XML data to the web of linked data. It provides examples of converting XML content like tables and files into linked data formats like Turtle and JSON-LD. It also demonstrates querying linked data from XML files using SPARQL and XSLT transformations and serving linked data from XML using Apache Jena Fuseki. The document aims to help integrate linked data processing into existing XML tooling and workflows.
Graph Database
This document discusses graph databases and provides an overview of Neo4j. It describes how graph databases are useful for modeling connected data and performing complex queries over relationships. The document outlines the benefits of graph databases like expressing the domain as a graph and using graph traversals for queries.

Graph Database and Neo4j
This document provides an overview of graph databases and Neo4j. It discusses how graph databases are better suited than relational databases for interconnected data and have simpler data models. Neo4j is highlighted as a graph database that uses nodes, edges and properties to represent data and uses the Cypher query language. It is fully ACID compliant, open source, and has a large active community.
Graph database
Graph databases use graph structures to represent and store data, with nodes connected by edges. They are well-suited for interconnected data. Unlike relational databases, graph databases allow for flexible schemas and querying of relationships. Common uses of graph databases include social networks, knowledge graphs, and recommender systems.
Ephedra: efficiently combining RDF data and services using SPARQL federation
The document describes Ephedra, a SPARQL federation engine that efficiently combines distributed RDF data and services using SPARQL queries. Ephedra extends the RDF4J API to treat compute services as virtual RDF repositories. It performs optimizations like reordering clauses, pushing limits/orders down, and parallel competing joins. An evaluation on cultural heritage and life science queries showed runtime improvements over no optimization. Future work includes backend-aware optimizations and collecting service statistics for improved planning. Ephedra provides an architecture for integrating diverse data sources and services through SPARQL federation.

Macmillan is developing a linked data platform and semantic data model to power discovery services for scientific content. They have created an RDF-based data model and ontology to organize over 270 million triples of metadata. They are focusing on internal use cases and have implemented a hybrid architecture using MarkLogic and a triplestore to optimize query performance and deliver content in under 200ms. Going forward, they aim to expand the ontology, enable more advanced querying, and establish the semantic data model as a core enterprise asset.
Scraping data from the web and documents
This document discusses web scraping and data extraction. It defines scraping as converting unstructured data like HTML or PDFs into machine-readable formats by separating data from formatting. Scraping legality depends on the purpose and terms of service - most public data is copyrighted but fair use may apply. The document outlines the anatomy of a scraper including loading documents, parsing, extracting data, and transforming it. It also reviews several scraping tools and libraries for different programming languages.

Connected data meetup group - introduction & scope
What is Connected Data as a concept? Who is interested in Connected Data? What problems does Connected Data solve? What skills are used in Connected Data?
Connected Data as of July 2017 has been running for over a year with very successful conference and 9 meetups held to date on a range of topics. These have included Knowledge Representation, Semantics, Linked Data, Graph Databases, Ontology development and use cases and industry verticals including recommendations, telecoms and finance. Yet the group has never had a particularly formal terms of reference or description defining what Connected Data actually means. Some would say this is something of a irony for a group so focused on semantics, schemas, definitions & structure!
This is an attempt (with some humour and something of journey included in it) to achieve something resembling a definition and terms of reference for the group.

Osgi
This document outlines a 5-step process to modularize the OpenMRS application using OSGi bundles. The first step is to create a "mega bundle" that includes all dependencies. The next three steps involve extracting the core API, web, and webapp modules into separate OSGi bundles. The final step is to define an execution plan for the Virgo OSGi server to run the modularized application as individual bundles. When completed, the OpenMRS application will be split into interoperable modules running within an OSGi container.

Linked Data
Linked Data allows evolving the web into a global data space by publishing structured data on the web using RDF and by linking data items across different data sources. It follows the Linked Data principles of using URIs to identify things and HTTP URIs to look up those names, providing useful RDF information when URIs are dereferenced, and including RDF links to discover related data. The amount of published Linked Data on the web has grown enormously since 2007. Large data sources like DBpedia extract structured data from Wikipedia and act as hubs by interlinking different data sets, enabling new applications and search over integrated data.
Question answering in linked data
The document discusses the evolution of the web from documents to data, and introduces linked data which publishes machine-readable data on the web that is explicitly defined and linked to other datasets. It then discusses question answering systems that take natural language questions and locate answers from document collections, including both closed-domain systems with restricted knowledge bases and open-domain systems that retrieve answers from the web. The document also presents the linked data technology stack and some examples of linked open data clouds from 2007 to 2011 to demonstrate the growth of linked data on the web.
Linked Data (1st Linked Data Meetup Malmö)
This document discusses Linked Data and outlines its key principles and benefits. It describes how Linked Data extends the traditional web by creating a single global data space using RDF to publish structured data on the web and by setting links between data items from different sources. The document outlines the growth of Linked Data on the web, with over 31 billion triples from 295 datasets as of 2011. It provides examples of large Linked Data sources like DBpedia and discusses best practices for publishing, consuming, and working with Linked Data.
DubJug: Neo4J and Open Data
The document discusses Neo4J and open data. It begins with an introduction of the speaker and agenda. It then provides an overview of NoSQL databases including features and types. It introduces Neo4J as a graph database and discusses its components. The document also discusses the Neo4J Object Graph Mapping (OGM) framework and open data concepts including definitions, guidelines, examples, and sources of open data. It demonstrates loading open data into Neo4J using Cypher queries and OGM.
Cloud-based Linked Data Management for Self-service Application Development

Key components of the platform include virtualized integration of data sources and the vision of accessing linked data as a cloud-based data service.
Echoes Project
This document provides an overview and update on the ECHOES project, which aims to create a modular IT architecture based on open source to allow heritage collection holders to function as a digital ecosystem. It discusses the project scope, design principles of being open, modular, and enabling innovation. It outlines the development methodology, and provides details on the implementation of various modules including the data sources module, data lake module, data retrieval and visualization module, and enrichment module. Key challenges addressed include handling heterogeneous data from different sources and ensuring data quality while incorporating large quantities of data. The document discusses lessons learned around having a modular architecture and balancing data quality with quantity.
Semantic Web: introduction & overview
The document provides an overview of semantic technologies and discusses their increasing mainstream adoption. It notes that Microsoft purchased Powerset in 2008, Apple purchased Siri in 2010, and Google bought Metaweb and released semantic search in 2013. It discusses how semantic technologies allow for interoperability through shared representations and reasoning. Examples are given of early semantic search applications from 1999-2002 and an operational semantic electronic medical record application deployed in 2006.
Link Sets And Why They Are Important (EDF2012)
This document discusses the importance of links between datasets on the semantic web. It outlines that while there are over 30 billion triples published as linked open data, less than 500 million of these are links between datasets. This limits the ability to connect data islands into a global web of data. The document then describes tools like the LATC platform that can help automate the process of identifying links between datasets through linkage rules and machine learning of rules.

Your Big Data Stack is Too Big!: Presented by Timothy Potter, Lucidworks
Timothy Potter presented at a Big Data conference in Boston from October 11-14, 2016. He discussed how Lucidworks Fusion provides an alternative to traditional big data stacks that emphasizes fast access, agility and automation over integration. Fusion allows for common access patterns like fast lookups, ranked retrieval and distributed scans while integrating technologies like Solr, Spark, HDFS and more. It provides tools for data ingestion, time-based partitioning, analytics, machine learning and more to solve business problems rather than focus on infrastructure.
JSON-LD and SHACL for Knowledge Graphs
Enterprise systems are increasingly complex, often requiring data and software components to be accessed and maintained by different company departments. This complexity often becomes an organization’s biggest challenge as changing data fields and adding new applications rapidly grow to meet business demands for increased customer insights.
These slides are from a Webinar discussing how using SHACL and JSON-LD with AllegroGraph helps our customers simplify the complexity of enterprise systems through the ability to loosely combine independent elements, while allowing the overall system to function smoothly.
In this Webinar we will demonstrate how AllegroGraph’s SHACL validation engine confirms whether JSON-LD data is conforming to the desired requirements. We will describe how SHACL provides a way for a Data Graph to specify the Shapes Graph that should be used for validation and describes how a given shape is linked to targets in the data.

CAKE: Sharing Slices of Confidential Data on Blockchain
Presented at the CAiSE 2024 Forum, Intelligent Information Systems, June 6th, Limassol, Cyprus.
Synopsis: Cooperative information systems typically involve various entities in a collaborative process within a distributed environment. Blockchain technology offers a mechanism for automating such processes, even when only partial trust exists among participants. The data stored on the blockchain is replicated across all nodes in the network, ensuring accessibility to all participants. While this aspect facilitates traceability, integrity, and persistence, it poses challenges for adopting public blockchains in enterprise settings due to confidentiality issues. In this paper, we present a software tool named Control Access via Key Encryption (CAKE), designed to ensure data confidentiality in scenarios involving public blockchains. After outlining its core components and functionalities, we showcase the application of CAKE in the context of a real-world cyber-security project within the logistics domain.

Climate Impact of Software Testing at Nordic Testing Days
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.
