  • Data in the Digital Age
    March 2019 Data in the Digital Age The growing interactions between data, algorithms and big data analytics, connected things and people are opening huge new opportunities. But they are also giving rise to issues around “data governance” at the national and international levels. These include questions around the management of data availability, accessibility, usability, integrity and security, as well as concerns about ownership, impacts on trade and competition, implications for personal privacy, and more. Policy makers across government are grappling with these issues. The use of digital technologies and data underpins digital transformation across all sectors of economies and societies, meaning that any policy decisions on data can have wide effects. Instilling trust in the use of data is a pre-condition for fully realising the gains of digital transformation. This in turn calls for policy makers to better understand and account for the heterogeneity of data, to take a strategic approach to its governance and ensure all policy objectives are considered, and to upgrade their own capabilities to harness data for better policy making. Key policy directions Recognise that there are different types of data, and measure the economic and social value of data and data flows. Many different types of data are collected and used, and their purpose and value can differ widely. Without recognising these different kinds of data, governments will not be able to effectively address issues such as personal data protection or competition. Better measurement of data and data flows and their role in production and value chains will also help support policy making. Develop national data strategies.

  • Knowledge Extraction by Internet Monitoring to Enhance Crisis Management
    El Hamali Knowledge Extraction by Internet Monitoring to Enhance Crisis Management Knowledge Extraction by Internet Monitoring to Enhance Crisis Management El Hamali Samiha Nadia Nouali-TAboudjnent, Omar Nouali National School for Computer Science ESI, Research Center of Scientific and Technique Algiers, Algeria Information CERIST, Algeria [email protected] {nnouali, onouali}@cerist.dz ABSTRACT This paper presents our work on developing a system for Internet monitoring and knowledge extraction from different web documents which contain information about disasters. This system is based on ontology of the disasters domain for the knowledge extraction and it presents all the information extracted according to the kind of the disaster defined in the ontology. The system disseminates the information extracted (as a synthesis of the web documents) to the users after a filtering based on their profiles. The profile of a user is updated automatically by interactively taking into account his feedback. Keywords Crisis management, internet monitoring, knowledge extraction, ontology, information filtering. INTRODUCTION Several crises and disasters happened in the last decades. After the southern Asian tsunami, the Katrina hurricane in the United States, and the Kashmir earthquake, people throughout the world used the Web as a source of information and a means of communication. In the hours and days immediately following a disaster, a lot of information becomes available on the web. With a single Google search, 17 millions “emergency management” sites and documents have been listed (Min & Peishih, 2008). The user finds a lot of information which comes from different sources, for instance : during the first 3 days of tsunami disaster in south-east Asia, 4000 reports were gathered by the Google News service, and within a month of the incident, 200000 distinct news reports from several online sources (Yiming, et al., 2007 IEEE).

  • Handling Semantic Complexity of Big Data Using Machine Learning and RDF Ontology Model
    S S symmetry Article Handling Semantic Complexity of Big Data using Machine Learning and RDF Ontology Model Rauf Sajjad *, Imran Sarwar Bajwa and Rafaqut Kazmi Department of Computer Science & IT, The Islamia University Bahawalpur, Bahawalpur 63100, Pakistan; [email protected] (I.S.B.); [email protected] (R.K.) * Correspondence: [email protected]; Tel.: +92-62-925-5466 Received: 3 January 2019; Accepted: 14 February 2019; Published: 1 March 2019 Abstract: Business information required for applications and business processes is extracted using systems like business rule engines. Since the advent of Big Data, such rule engines are producing rules in a big quantity whereas more rules lead to more complexity in semantic analysis and understanding. This paper introduces a method to handle semantic complexity in rules and support automated generation of Resource Description Framework (RDF) metadata model of rules and such model is used to assist in querying and analysing Big Data. Practically, the dynamic changes in rules can be a source of conflict in rules stored in a repository. It is identified during the literature review that there is a need of a method that can semantically analyse rules and help business analysts in testing and validating the rules once a change is made in a rule. This paper presents a robust method that not only supports semantic analysis of rules but also generates RDF metadata model of rules and provide support of querying for the sake of semantic interpretation of the rules. The results of the experiments manifest that consistency checking of a set of big data rules is possible through automated tools.

  • A Comparison of Knowledge Extraction Tools for the Semantic Web
    A Comparison of Knowledge Extraction Tools for the Semantic Web Aldo Gangemi1;2 1 LIPN, Universit´eParis13-CNRS-SorbonneCit´e,France 2 STLab, ISTC-CNR, Rome, Italy. Abstract. In the last years, basic NLP tasks: NER, WSD, relation ex- traction, etc. have been configured for Semantic Web tasks including on- tology learning, linked data population, entity resolution, NL querying to linked data, etc. Some assessment of the state of art of existing Knowl- edge Extraction (KE) tools when applied to the Semantic Web is then desirable. In this paper we describe a landscape analysis of several tools, either conceived specifically for KE on the Semantic Web, or adaptable to it, or even acting as aggregators of extracted data from other tools. Our aim is to assess the currently available capabilities against a rich palette of ontology design constructs, focusing specifically on the actual semantic reusability of KE output. 1 Introduction We present a landscape analysis of the current tools for Knowledge Extraction from text (KE), when applied on the Semantic Web (SW). Knowledge Extraction from text has become a key semantic technology, and has become key to the Semantic Web as well (see. e.g. [31]). Indeed, interest in ontology learning is not new (see e.g. [23], which dates back to 2001, and [10]), and an advanced tool like Text2Onto [11] was set up already in 2005. However, interest in KE was initially limited in the SW community, which preferred to concentrate on manual design of ontologies as a seal of quality. Things started changing after the linked data bootstrapping provided by DB- pedia [22], and the consequent need for substantial population of knowledge bases, schema induction from data, natural language access to structured data, and in general all applications that make joint exploitation of structured and unstructured content.

  • CN-Dbpedia: a Never-Ending Chinese Knowledge Extraction System
    CN-DBpedia: A Never-Ending Chinese Knowledge Extraction System Bo Xu1,YongXu1, Jiaqing Liang1,2, Chenhao Xie1,2, Bin Liang1, B Wanyun Cui1, and Yanghua Xiao1,3( ) 1 Shanghai Key Laboratory of Data Science, School of Computer Science, Fudan University, Shanghai, China {xubo,yongxu16,jqliang15,xiech15,liangbin,shawyh}@fudan.edu.cn, [email protected] 2 Data Eyes Research, Shanghai, China 3 Shanghai Internet Big Data Engineering and Technology Center, Shanghai, China Abstract. Great efforts have been dedicated to harvesting knowledge bases from online encyclopedias. These knowledge bases play impor- tant roles in enabling machines to understand texts. However, most cur- rent knowledge bases are in English and non-English knowledge bases, especially Chinese ones, are still very rare. Many previous systems that extract knowledge from online encyclopedias, although are applicable for building a Chinese knowledge base, still suffer from two challenges. The first is that it requires great human efforts to construct an ontology and build a supervised knowledge extraction model. The second is that the update frequency of knowledge bases is very slow. To solve these chal- lenges, we propose a never-ending Chinese Knowledge extraction system, CN-DBpedia, which can automatically generate a knowledge base that is of ever-increasing in size and constantly updated. Specially, we reduce the human costs by reusing the ontology of existing knowledge bases and building an end-to-end facts extraction model. We further propose a smart active update strategy to keep the freshness of our knowledge base with little human costs. The 164 million API calls of the published services justify the success of our system.

The growing amount of Web data provides the world’s largest collection of knowledge.1 Most of this full-text data like blogs, news or encyclopaedic informa- tion is textual in nature. However, the increasing amount of structured respectively semantic data2 available on the Web fosters new search paradigms. These novel paradigms ease the development of natural language interfaces which enable end- users to easily access and benefit from large amounts of data without the need to understand the underlying structures or algorithms.

  • 6 Ways Digital Transformation Is Reshaping the World
    6 Ways Digital Transformation is Reshaping the World Brought to you by the Stanford Digital Transformation Program. ONLINE Contents 1. Introduction 2. Personalized Digital Experiences 3. Business Run from the Cloud 4. Data-Driven Decision Making 5. The Internet of Things 6. Accelerated Business Processes with Automation 7. Artificial Intelligence 8. Conclusion – The Future of Digital Transformation ONLINE Introduction Digital transformation is reshaping the world. It is accelerating the pace of technical and organizational innovation, empowering new market entrants, and generating new categories of goods and services that are, in turn, altering how we live, work, and play. While the term can be defined in a variety of ways, digital transformation typically references two fundamental shifts: • a transformation in the effectiveness and sophistication of digital technologies • the adoption of new business cultures to facilitate digital transformation These shifts are being driven by the promise of increased agility and greater cost efficiencies and are enabled by a set of powerful new digital tools that include cloud computing, artificial intelligence, and predictive analytics. But they also require that organizations rethink how they use technology, people, and business processes. That is a complex undertaking and far from simple to master. It typically requires executive support and the assembly of dedicated teams trained specifically for the effort. Yet the pressures to change are immense. Digital transformation enables startup companies to develop new goods and services that can disrupt existing markets and increase customer expectations, e.g. gig economy services, self-driving automobile technologies, precision agriculture, customized 3D printed parts, and app-based payment systems.

  • A Technical Overview of Digital Credentials
    A Technical Overview of Digital Credentials Dr. Stefan Brands Credentica [email protected] February 20, 2002 Abstract Applications that involve the electronic transfer of credentials, value tokens, profiles, and other sensitive information are quickly gaining momentum. Traditional attempts to introduce electronic authentication, such as PKI and biometric verification, expose organizations to po- tentially unlimited liability, lead to consumer fear, and stifle the adoption of new systems. To overcome these barriers, innovative solutions are needed that address the entire spectrum of security and privacy interests for all parties involved. This paper is a technical overview of Digital Credentials. Digital Credentials are the digital equivalent of paper documents, plastic tokens, and other tangible objects issued by trusted parties. At the same time, they are much more powerful than their physical counterparts. For example, individuals can selectively disclose properties of the data fields in their Digital Credentials while hiding any other information. Digital Credentials also provide much greater security. As a result, they can be used to securely implement objects that traditionally are made identifiable in order to deal with certain kinds of fraud. Examples are diplomas, work permits, access cards, and drivers’ licenses. 1 Introduction Around the world, influential organizations are rushing to provide individuals with digital identity certificates that will be the sole means of participating in their systems. Among the front-runners are telecommunication organizations, health care providers, mobile service providers, financial institutions, and state and federal governments. A digital identity certificate is just a sequence of zeros and ones, and so it can be transferred electronically and can be verified with 100 percent accuracy by computers.
