The open semantic enterprise enterprise data meets web dataGeorg Guentner
Presentation in workshop at the 2nd B2B Software Days (11.04.2013, Vienna), together with Herbert Beilschmidt (Oracle Austria):
The Open Semantic Enterprise.Enterprise Data meets Web Data.
The technologies of the “Web od Data” have reached a degree of maturity and acceptance allowing the productive use in enterprises for the support of their business processes. Though the focus is currently on the adoption and use of Open (Linked) Data, the underlying principles can also be applied to the closed data sources and proprietary data structures usually available in enterprises.
The workshop outlines the conceptual and architectural approaches to open enterprise data sources and interweave them with the Web of Data. It shows concrete application scenarios of an open source “semantic toolset” that can be integrated with enterprise information and content management systems to open data silos, establish a layer of adaptive integrated views of the enterprise information and support decision processes thus paving the way to an “open semantic enterprise”.
The topical semantic toolset for enterprise content integration includes Apache Stanbol (knowledge extraction), Apache Marmotta (Linked Data Platform), the Linked Media Framework (networked knowledge) und VIE (interactive knowledge).
State-of-the-art big data platforms need to process massive quantities of data in batch and in parallel - filtering, transforming and sorting it before loading it into an enterprise data warehouse. In order to realize an Open Semantic Enterprise, a big data platform has to be optimized for acquiring, organizing, and loading unstructured data. Technological approaches such as NoSQL databases and connectors for Apache Hadoop complement big data solutions for the open world of a semantic enterprise.

SharePoint’s rapid adoption is undeniable but it raises one important question: What security capabilities did Microsoft implement to ensure that SharePoint--and the data it houses--remains secure? SharePoint’s functionality was built for business users to share information. However, business users don’t typically recognize critical security considerations. This leaves security teams with the task of layering security onto SharePoint well after deployments, or worse, after a data breach. These presentation slides highlight SharePoint use cases and potential security issues , offer best practices for SharePoint security planning and management, and provide key mitigation steps that enterprises implement to minimize the odds of a data breach.

With the adoption of responsive design, we’re finding that our pixel-perfect content is no longer being placed in pixel-perfect boxes on pixel-perfect websites. Placeholder content no longer suffices during development. Copy-and-paste doesn’t work in migrating between designs. Rather, website design is more strongly informed by our content than ever before. With these changes we need to rethink how content affects our development workflow as well as understand how content and messaging affect layouts.
• Learn why you need to be an advocate for content at all phases of a project.
• Explore the fundamental content types and content rules that will shape how your content flows and is viewed by visitors.
• Learn how content choreography can help you keep your most important message the focus of your site.

The future of Content management when the mobile Broadcasts Intent Tony Fish
Mobile has many advantages and new ones keep appearing. Given that the mobile is available at the point of inspiration we have learnt to capture content and share it……
The mobile is also available at our point of need.
The market structure today for need is based on the ability to deliver relevant search based on context but this is being challenged by intent. Aka CMS and CRM
Intent is where the user is in control.
The user broadcasts what they need and local providers bid to meet the need. This is a significant change that will find it place and it will affect how companies offer and deliver services.
Catherine van Zuylen, Vice President of Global Product Management at Attensity talks about the future of text analytics at The Text Alalytics Summit West 2012
I presented on this topic last Thursday at the AIIM National Capital Chapter breakfast meeting. I had a great time presenting my view of what the future may hold and talked about some of the clues that we may have been able to pick up at the recent AIIMexpo 2007 in Boston.
Based on interviews with users and analysts, Neos is now offering a user interface that concentrates on the creation of efficiently communicating content. The overall goal for Neos is to become a system that helps any organisation at optimizing the web experience they are offering. Carefully pre-configured defaults provide editors with helpful guidelines and intelligent templates. Content is edited side-by-side with statistics that help to measure and improve performance. Neos integrates planning and collaboration tools for the team members to bring everyone on the same page in concerted digital marketing efforts. Empowered by an "Open Suite" approach to integration, Neos aims to become the central hub for the digital marketing team, embedding all relevant data from all sorts of sources. We believe too much of digital marketeers' time and effort is lost today because of scattered information across too many platforms, fuzzy goals and lack of transparent performance measurement. The Neos Team defines the CMS of the future as the pivotal resource that combines all necessary information and provides a streamlined environment for editors and developers to act on that feedback.

Graph Databases and the Future of Large-Scale Knowledge ManagementMarko Rodriguez
Modern day open source and commercial graph databases can store on the order of 1 billion relationships with some databases reaching the 10 billion mark. These developments are making the graph database practical for applications that require large-scale knowledge structures. Moreover, with the Web of Data standards set forth by the Linked Data community, it is possible to interlink graph databases across the web into a giant global knowledge structure. This talk will discuss graph databases, their underlying data model, their querying mechanisms, and the benefits of the graph data structure for modeling and analysis.
The End Of Control and the Future of Content: Futurist Gerd Leonhard Authors@...Gerd Leonhard
When every song, every movie, every book and every image can easily be found and shared via high-speed digital networks, and any actual control of the flow of content becomes a thing of the past, how will content creators and their respective industries generate growing revenues, in the future? When search becomes media, and advertising becomes content, what's the future of creativity? Which precise new generatives (>Kevin Kelly) can be nurtured to build this new ecosystem of search, content and communications, based on access to content rather than copies?

Stories have helped us connect with our fellow human beings since the dawn of time. But as we have evolved, each new communication platform creates opportunities and challenges, especially for brands.
Brands have learned that promoting themselves doesn't work. Ultimately it's the stories that allow brands to connect with their audience. The future of marketing is extreme customer-centricity.
Brands have to stop promoting themselves and create content that people actually want to consumer. The future of marketing will see more brands acting like publishers. This is more than a cliche. It means brands will start delivering content people want. And driving engagement and conversions.
As content consumers, we react more quickly and with deeper connection to headlines that engage us with curiosity and wit. The future of marketing uses the words we use when searching online and drives action with engaging headlines.
The world is overflowing with more information than any of us could ever dream of consuming. But "a picture is worth a thousand words." The future of marketing is more visual as brands follow traditional media publishers into visual content production. Brands will hire photographers, designers, reporters and videographers in addition to journalists.
The term "real-time marketing" is a myth. It is an over-simplification of the complexity of the modern world and how brands need to act in order to stay relevant. We are always-on and always-connected. The "campaign brain" no longer fits the world we live in. Campaigns that provide short-term bumps of engagement do not provide the return that marketing investment requires.
Brands cannot determine when and where lightning will strike. And so the future of marketing will see marketing leaders creating a culture of continuous always-on content production.
Social media is not a strategy. It is one of the channels we use to consume content and connect with people. It is the evolution of what started with the dawn of the internet and the move to digital, mobile and cloud-based systems of communications. These are just the pipes. Content is the fuel.
In order to be effective in the future, brands must create branded content hubs to attract their own audiences. The future of marketing is owned media and branded content hubs, driving social engagement that fuels paid distribution.
Next-level collaboration: The future of content and design | Confab 2015Rebekah Baggs
Imagine a future where siloed departments and legacy workflows don’t stand in our way. Today’s content is complex, interconnected, and needs to be ready for devices we haven’t even dreamed of yet. Tomorrow isn’t going to get any simpler. Successful outcomes demand a new kind of collaboration.
For the past two years, Rebekah has studied how successful teams collaborate and has helped transform the way her team works and produces together. In this session, you’ll hear what she’s learned about making effective cross-discipline collaboration possible, and leave with actionable approaches you can use to unite your team and workflow, too.
In this talk, we discussed:
- What it takes to make effective collaboration possible
- How content strategists play a key role in creating the cross-discipline teams of tomorrow
- Practical techniques you can use to bridge silos, increase productivity, and deliver better project outcomes for everyone
Indoor Positioning Using the OpenHPS FrameworkBeat Signer
Research paper presentation given at IPIN 2021, Lloret de Mar, Spain.
Hybrid positioning frameworks use various sensors and algorithms to enhance positioning through different types of fusion. The optimisation of the fusion process requires the testing of different algorithm parameters and optimal lowas well as high-level sensor fusion techniques. The presented OpenHPS open source hybrid positioning system is a modular framework managing individual nodes in a process network, which can be configured to support concrete positioning use cases or to adapt to specific technologies. This modularity allows developers to rapidly develop and optimise their positioning system while still providing them the flexibility to add their own algorithms. In this paper we discuss how a process network developed with OpenHPS can be used to realise a customisable indoor positioning solution with an offline and online stage, and how it can be adapted for high accuracy or low latency. For the demonstration and validation of our indoor positioning solution, we further compiled a publicly available dataset containing data from WLAN access points, BLE beacons as well as several trajectories that include IMU data.

Personalised Learning Environments Based on Knowledge Graphs and the Zone of ...Beat Signer
Presentation given at CSEDU 2022, Virtual Event.
The learning of new knowledge and skills often requires previous knowledge, which can lead to some frustration if a teacher does not know a learner's exact knowledge and skills and therefore confronts them with exercises that are too difficult to solve. We present a solution to address this issue when teaching techniques and skills in the domain of table tennis, based on the concrete needs of trainers that we have investigated in a survey. We present a conceptual model for the representation of knowledge graphs as well as the level at which individual players already master parts of this knowledge graph. Our fine-grained model enables the automatic suggestion of optimal exercises in a player's so-called zone of proximal development, and our domain-specific application allows table tennis trainers to schedule their training sessions and exercises based on this rich information. In an initial evaluation of the resulting solution for personalised learning environments, we received positive and promising feedback from trainers. We are currently investigating how our approach and conceptual model can be generalised to some more traditional educational settings and how the personalised learning environment might be further improved based on the expressive concepts of the presented model.

Codeschool in a Box: A Low-Barrier Approach to Packaging Programming CurriculaBeat Signer
Presentation given at CSEDU 2023, Prague, Czech Republic.
The tech industry is a fast-growing field, with many companies facing issues in finding skilled workers to fill their open vacancies. At the same time, many people have limited access to the quality education necessary to enter this job market. To address this issue, various small and often volunteer-run non-profit organisations have emerged to up-skill capable learners. However, these organisations face tight constraints and many challenges while trying to design and deliver high-quality education to their learners. In this position paper, we discuss some of these challenges and present a preliminary version of a curriculum packager addressing some of these issues. Our proposed solution, inspired by first-hand experience in these organisations as well as computing education research (CER), is based on a combination of micromaterials, study lenses and a companion mobile application. While our solution is designed for the specific context of small organisations providing vocational ICT training, it can also be applied to the broader domain of learning environments facing similar constraints.

Towards a Framework for Dynamic Data PhysicalisationBeat Signer
Presentation given at the International Workshop Toward a Design Language for Data Physicalization, Berlin, Germany, October 2018
ABSTRACT: Advanced data visualisation techniques enable the exploration and analysis of large datasets. Recently, there is the emerging field of data physicalisation, where data is represented in physical space (e.g. via physical models) and can no longer only be explored visually, but also by making use of other senses such as touch. Most existing data physicalisation solutions are static and cannot be dynamically updated based on a user's interaction. Our goal is to develop a framework for new forms of dynamic data physicalisation in order to support an interactive exploration and analysis of datasets. Based on a study of the design space for dynamic data physicalisation, we are therefore working on a grammar for representing the fundamental physical operations and interactions that can be applied to the underlying data. Our envisioned extensible data physicalisation framework will enable the rapid prototyping of dynamic data physicalisations and thereby support researchers who want to experiment with new combinations of physical variables or output devices for dynamic data physicalisation as well as designers and application developers who are interested in the development of innovative dynamic data physicalisation solutions.

Add geographical metadata (latitude, longitude) to
different types of media
websites
- e.g. special Geo microformat
photographs
videos
RSS feeds
...
Metadata can be added manually or automatically
e.g. recent digital cameras automatically geotag new pictures

19. Location-Based Search
Location-based queries
for nearby services and
route finding
e.g. Google maps
map-based data fusion
Location-aware querying
can be combined with
social networking
e.g. foursquare
check-in at specific places
and get tips from colleagues
what about privacy?

21. Audio-Based Search
Audio search engines use
acoustic fingerprints of
recorded audio samples
use mobile phone micro-
phone to record a few
seconds of a song
send query to server
e.g. SoundHound or Shazam
Query by Humming (QbH)
find similar songs based on a
hummed melody
e.g. musipedia

22. Internet of Things
In the future we will see more and more network- or
Internet-enabled physical objects
Physical objects get linked to digital information and
services offered in the cloud
How many objects will there be?
estimates of 100'000 billion and more objects
Is a simple tagging via RFID tags or barcodes enough?
e.g. Barcode Hero or RedLaser
what if only a part of an object should be linked to data?
Is the simple mapping to a web presence (URI) enough?

25. Image-Based Search
Reverse image search
engines to find different
versions of an image
e.g. TinEye
Image-based querying of
textual information
e.g. Google Goggles
Image retrieval with face
recognition
e.g. Flickr
what about privacy if used on
a global scale?

26. Personalisation
To deal with the sheer amount of data, we can apply
semantic filtering and recommedation on the web of data
The filtering and recommendation can be based on
personal profiling
- monitoring a user's interaction with the global machine
social profiling
- investigate a user's social network
item classication
- find similar items based on intrinsic properties as well as collaborative
annotations
September 12, 2011 Beat Signer - Department of Computer Science - bsigner@vub.ac.be 26
27. Social Search
Web search that makes
use of the Social Graph
for result ranking
e.g. Google Social Search
comments and input from
friends
note the similarity to
PageRank
Queries can also be
outsourced to colleagues
via Twitter, Facebook etc.

people less likely remember things that they
believe to be accessible online
Internet as a transactive memory
Does our memory work differently in the age of Google?
What implications will the future of the Internet and new
search have?
