Web Data Extraction, Applications and Techniques: A Survey
Web Data Extraction is an important problem that has been studied by means of
different scientific tools and in a broad range of applications. Many
approaches to extracting data from the Web have been designed to solve specific
problems and operate in ad-hoc domains. Other approaches, instead, heavily
reuse techniques and algorithms developed in the field of Information
Extraction.
This survey aims at providing a structured and comprehensive overview of the
literature in the field of Web Data Extraction. We provided a simple
classification framework in which existing Web Data Extraction applications are
grouped into two main classes, namely applications at the Enterprise level and
at the Social Web level. At the Enterprise level, Web Data Extraction
techniques emerge as a key tool to perform data analysis in Business and
Competitive Intelligence systems as well as for business process
re-engineering. At the Social Web level, Web Data Extraction techniques allow
to gather a large amount of structured data continuously generated and
disseminated by Web 2.0, Social Media and Online Social Network users and this
offers unprecedented opportunities to analyze human behavior at a very large
scale. We discuss also the potential of cross-fertilization, i.e., on the
possibility of re-using Web Data Extraction techniques originally designed to
work in a given domain, in other domains.Comment: Knowledge-based System

The Use of Hosted Enterprise Applications by SMEs: A Dual Market and User Perspective
YesThis deliberately dual perspective paper seeks to deepen our understanding of the engagement of SMEs in hosted enterprise applications in the UK. The emergence and development of the ASP sector has attracted much interest and highly optimistic forecasts for revenues. The paper starts by considering ICT adoption by SMEs in general before reviewing the provision of hosted enterprise applications in the US and UK (market perspective). The study is extended by qualitative empirical data collected by semi-structured interviews with SME users of hosted enterprise applications (user perspective) and subsequent analysis in order to develop the key findings and conclusions. From an SME user perspective the key findings to emerge from the study include: i) confirmation that ICT infrastructure was no longer a barrier to adoption, ii) the pragmatic approach taken to security issues, iii) the use of both multiple information systems and multiple service providers, iv) the financial attractiveness of the rental model and v) the intention to continue or extend the use of hosted applications. It also highlights the opportunity for gaining competitive advantage by using hosted enterprise applications to reduce costs. There are very few empirical studies of hosted applications which take deliberately market and SME user perspectives - this paper makes an important contribution in this emerging field

FIDE Congress 2020 - EU Competition Law and the Digital Economy: United Kingdom Report
This report was prepared for the 29th biennial Congress of the International Federation of European Law (FIDE) to be held in The Hague in May 2020. It is the national report for the United Kingdom in response to Topic 3 of the 2020 FIDE Congress, titled ‘EU Competition Law and the Digital Economy’. This report offers an overview of UK competition enforcement in digital economy markets by answering twelve questions organised into four sections. Part A summarises key UK antitrust and merger decisions, agency publications, priorities and goals of enforcement in digital economy markets. Part B focuses upon the definition of markets and conceptualisation of market power by UK authorities in digital economy cases in light of their challenges and particularities. Part C offers a detailed overview of the issues underpinning UK antitrust and merger scrutiny in this field: the types of conduct investigated, relevant factors and concepts, theories of harm, efficiency justifications and remedies in digital economy cases. Finally, Part D identifies the potential for incoherent enforcement in this field from two different sources: the overlap between UK competition law and ex ante regulatory regimes (e.g. consumer protection, data protection); and the overlap between the powers of various UK competition decision-makers (e.g. sectoral regulators, the Competition Appeal Tribunal, and the courts)
The Use of Hosted Enterprise Applications by SMEs: A User Perspective
This paper seeks to deepen our understanding of the engagement of small to medium-sized enterprises (SMEs) in hosted enterprise applications (high complexity e-business applications) in the UK by investigating the relevance of organisational and technical factors through conducting interviews with SME users of hosted applications. The emergence and development of the application service provider (ASP) sector has attracted much interest and highly optimistic forecasts for revenues. Of particular interest in this paper is the emergence of service offerings targeted specifically at SMEs. The paper starts by considering information technology (IT) adoption by SMEs in general before reviewing the provision of hosted enterprise applications in the US and UK. The empirical data collected from SME users of hosted enterprise applications is then analysed in order to produce the key findings and conclusions. From an SME user perspective the key findings to emerge from the study include: i) confirmation that ICT infrastructure was no longer a barrier to adoption, ii) the pragmatic approach taken to security issues, iii) the use of both multiple information systems (hosted and resident) and service providers, iv) the attractiveness of the rental cost model and v) the intention to continue or extend their use of hosted applications within the enterprise. The early promise of the ASP sector appears not to have been generally realised for SMEs in the UK. This study explores the experience of early adopters of this new IT related innovation and identifies some significant business gains experienced by SME users. It also highlights the opportunity for gaining competitive advantage by using hosted enterprise applications to reduce costs. There are very few empirical studies of hosted applications which take a deliberately SME user perspective and this paper make an important contribution in this emerging field
Pando: Personal Volunteer Computing in Browsers
The large penetration and continued growth in ownership of personal
electronic devices represents a freely available and largely untapped source of
computing power. To leverage those, we present Pando, a new volunteer computing
tool based on a declarative concurrent programming model and implemented using
JavaScript, WebRTC, and WebSockets. This tool enables a dynamically varying
number of failure-prone personal devices contributed by volunteers to
parallelize the application of a function on a stream of values, by using the
devices' browsers. We show that Pando can provide throughput improvements
compared to a single personal device, on a variety of compute-bound
applications including animation rendering and image processing. We also show
the flexibility of our approach by deploying Pando on personal devices
connected over a local network, on Grid5000, a French-wide computing grid in a
virtual private network, and seven PlanetLab nodes distributed in a wide area
network over Europe.Comment: 14 pages, 12 figures, 2 table
