The document discusses how to study the social web from various perspectives. It covers analyzing large datasets to understand phenomena, modeling the web as a graph to understand its structure and growth, and studying how simple micro-level rules give rise to complex macro-level behaviors. Challenges include the web changing faster than our ability to observe it and different parts of society having conflicting needs from the web. Open questions are discussed around whether open access of information is beneficial long-term and how the web impacts society.

#mytweet via Instagram: Exploring User Behaviour Across Multiple Social NetworksBang Hui Lim
We study how users of multiple online social net- works (OSNs) employ and share information by studying a common user pool that use six OSNs – Flickr, Google+, Instagram, Tumblr, Twitter, and YouTube. We analyze the temporal and topical signature of users’ sharing behaviour, showing how they exhibit distinct behaviorial patterns on different networks. We also examine cross-sharing (i.e., the act of user broadcasting their activity to multiple OSNs near-simultaneously), a previously unstudied behaviour and demonstrate how certain OSNs play the roles of originating source and destination sinks.

The “use” of an electronic resource from a social network analysis perspectiveMarie Kennedy
Presented at QQML 2013: Qualitative and Quantitative Methods in Libraries International Conference. Rome, Italy.
Academic libraries in the United States typically reference proxy server and/or COUNTER statistics to describe the usage of their electronic resources, but we know that a “use” is arguably more than a resource accessed or downloaded. This article employs social network analysis to bridge the typical ways of talking about usage statistics, to provide a context-specific perspective about the mediated use of electronic resources. The article reports on an analysis of data gathered at the Loyola Marymount University (Los Angeles, California) using traditional statistics as well as library reference encounters with patrons during which an electronic resource is mentioned. We use the reference encounters in a social network analysis to examine the relationship between a patron, a librarian, and an electronic resource to more fully describe the use of the resource. This research provides a conceptual model for comparison between traditional COUNTER statistics, proxy server statistics, and the social network analysis perspective. We transform qualitative data into quantitative data in order to develop a grounded theory about the mediated access to library electronic resources.

Walking Our Way to the Web - Fabien Gandon
The Web: Scientific Creativity, Technological Innovation and Society
XXVIII Conference on Contemporary Philosophy and Methodology of Science
9 and 10 March 2023
University of A Coruña
The prospect of Walking our Way to the Web may sound strange to contemporary readers of this article for whom the Web is omnipresent. However, the slogan of the World Wide Web Consortium (W3C) has been, for years, and remains today, to lead “the Web to its full potential” meaning we haven’t reached that potential yet, whatever it is. The first architect of the Web himself, Tim Berners-Lee, said in an interview in 2009: “The Web as I envisaged it, we have not seen it yet. The future is still so much bigger than the past”. And he is still very active, together with the W3C members and Web experts world-wide, in proposing evolutions of the Web architecture to improve its growing usages and applications. In this article we will review the path that led us to the actual Web, the shape it is taking now and the possible evolutions, good and bad, we can identify today. This will lead us to consider the distance that we witness between the initial vision and the reality of the Web today, and to reflect on the possible divergence between the potential we see in the Web and the directions it could take. Our goal in this article is to reflect on how we could walk the delicate path to the full potential of the Web, finding the missing links and avoiding the one too many links.
Web-scale Discovery Services are becoming an integral part of libraries' information gathering arsenal. These services are able to use a single interface to seamlessly integrate results from a wide range of online sources, emulating the experience patrons have come to expect from Internet search engines. But despite their ability to streamline searching, discovery services provide a wide set of challenges for libraries who implement them. This virtual conference will touch on both the potential of discovery services as well as some of the issues involved.
Hypermedia-driven Socio-technical Networks for Goal-driven Discovery in the W...Andrei Ciortea
To cope with dynamic environments, Internet of Things (IoT) applications are expected to autonomously discover and interact with services at runtime in pursuit of design or user-specified goals. On the one hand, various paradigms and technologies are available to program goal-driven autonomous software agents, and on the other hand hypermedia-driven environments are central to the development of robust machine-to-machine applications. However, existing approaches for the development of hypermedia-driven environments fall short of meeting the needs of autonomous agents: they either severely restrict the agents’ autonomy, or their topological structure is either fragmented or inefficient to navigate at scale. In this paper, we explore the use of socio-technical networks, that is networks of people and things interrelated in a meaningful manner via typed relations, as an overlay for enhancing hypermedia-driven interaction in IoT environments. We present a proof of concept and discuss several classes of applications in which this model could prove useful.
Linked Data Love: research representation, discovery, and assessment
#ALAAC15
The explosion of linked data platforms and data stores over the last five years has been profound – both in terms of quantity of data as well as its potential impact. Research information systems such as VIVO (www.vivoweb.org) play a significant role in enabling this work. VIVO is an open source, Semantic Web-based application that provides an integrated, searchable view of the scholarly activities of an organization. The uniform semantic structure of VIVO-ISF data enables a new class of tools to advance science. This presentation will provide a brief introduction and update to VIVO and present ways that this semantically-rich data can enable visualizations, reporting and assessment, next-generation collaboration and team building, and enhanced multi-site search. Libraries are uniquely positioned to facilitate the open representation of research information and its subsequent use to spur collaboration, discovery, and assessment. The talk will conclude with a description of ways librarians are engaged in this work – including visioning, metadata and ontology creation, policy creation, data curation and management, technical, and engagement activities.

The workshop opens with a discussion of how to repurpose digital "methods of the medium" for social and cultural scholarly research, including its limitations, critiques and ethics. Subsequently participants are trained in using digital methods in hands-on sessions. How to use crawlers for dynamic URL sampling and issue network mapping? How to employ scrapers to create a bias or partisanship diagnostic instrument? We also consider how to deploy online platforms for social research. How to transform Wikipedia from an online encyclopaedia to a device for cross-cultural memory studies? How to make use of social media so as to profile the preferences and tastes of politicians’ friends, and also locate most engaged with content? How to make use of Twitter analytics to debanalize tweets, and provide compelling accounts of events on the ground? Finally, the workshop turns to the question of employing web data and metrics as societal indices more generally.

The Rijksmuseum Collection as Linked DataLora Aroyo
Presentation at ISWC2018: http://iswc2018.semanticweb.org/sessions/the-rijksmuseum-collection-as-linked-data/ of our paper published originally in the Semantic Web Journal: http://www.semantic-web-journal.net/content/rijksmuseum-collection-linked-data-2
Many museums are currently providing online access to their collections. The state of the art research in the last decade shows that it is beneficial for institutions to provide their datasets as Linked Data in order to achieve easy cross-referencing, interlinking and integration. In this paper, we present the Rijksmuseum linked dataset (accessible at http://datahub.io/dataset/rijksmuseum), along with collection and vocabulary statistics, as well as lessons learned from the process of converting the collection to Linked Data. The version of March 2016 contains over 350,000 objects, including detailed descriptions and high-quality images released under a public domain license.
FAIRview: Responsible Video Summarization @NYCML'18Lora Aroyo
Presentation at the NYC Media Lab (NYCML2018). There is a growing demand for news videos online, with more consumers preferring to watch the news than read or listen to it. On the publisher side, there is a growing effort to use video summarization technology in order to create easy-to-consume previews (trailers) for different types of broadcast programs. How can we measure the quality of video summaries and their potential to misinform? This workshop will inform participants about automatic video summarization algorithms and how to produce more “representative” video summaries. The research presented is from the FAIRview project and is supported by the Digital News Innovation Fund (DNI Fund), which is part of the Google News Initiative.

Crowdsourcing ambiguity aware ground truth - collective intelligence 2017Lora Aroyo
The process of gathering ground truth data through human annotation is a major bottleneck in the use of information extraction methods. Crowdsourcing-based approaches are gaining popularity in the attempt to solve the issues related to the volume of data and lack of annotators. Typically these practices use inter-annotator agreement as a measure of quality. However, this assumption often creates issues in practice. Previous experiments we performed found that inter-annotator disagreement is usually never captured, either because the number of annotators is too small to capture the full diversity of opinion, or because the crowd data is aggregated with metrics that enforce consensus, such as majority vote. These practices create artificial data that is neither general nor reflects the ambiguity inherent in the data.
To address these issues, we proposed the method for crowdsourcing ground truth by harnessing inter-annotator disagreement. We present an alternative approach for crowdsourcing ground truth data that, instead of enforcing an agreement between annotators, captures the ambiguity inherent in semantic annotation through the use of disagreement-aware metrics for aggregating crowdsourcing responses. Based on this principle, we have implemented the CrowdTruth framework for machine-human computation, that first introduced the disagreement-aware metrics and built a pipeline to process crowdsourcing data with these metrics.
In this paper, we apply the CrowdTruth methodology to collect data over a set of diverse tasks: medical relation extraction, Twitter event identification, news event extraction and sound interpretation. We prove that capturing disagreement is essential for acquiring a high-quality ground truth. We achieve this by comparing the quality of the data aggregated with CrowdTruth metrics with a majority vote, a method which enforces consensus among annotators. By applying our analysis over a set of diverse tasks we show that, even though ambiguity manifests differently depending on the task, our theory of inter-annotator disagreement as a property of ambiguity is generalizable.
My ESWC 2017 keynote: Disrupting the Semantic Comfort ZoneLora Aroyo
Ambiguity in interpreting signs is not a new idea, yet the vast majority of research in machine interpretation of signals such as speech, language, images, video, audio, etc., tend to ignore ambiguity. This is evidenced by the fact that metrics for quality of machine understanding rely on a ground truth, in which each instance (a sentence, a photo, a sound clip, etc) is assigned a discrete label, or set of labels, and the machine’s prediction for that instance is compared to the label to determine if it is correct. This determination yields the familiar precision, recall, accuracy, and f-measure metrics, but clearly presupposes that this determination can be made. CrowdTruth is a form of collective intelligence based on a vector representation that accommodates diverse interpretation perspectives and encourages human annotators to disagree with each other, in order to expose latent elements such as ambiguity and worker quality. In other words, CrowdTruth assumes that when annotators disagree on how to label an example, it is because the example is ambiguous, the worker isn’t doing the right thing, or the task itself is not clear. In previous work on CrowdTruth, the focus was on how the disagreement signals from low quality workers and from unclear tasks can be isolated. Recently, we observed that disagreement can also signal ambiguity. The basic hypothesis is that, if workers disagree on the correct label for an example, then it will be more difficult for a machine to classify that example. The elaborate data analysis to determine if the source of the disagreement is ambiguity supports our intuition that low clarity signals ambiguity, while high clarity sentences quite obviously express one or more of the target relations. In this talk I will share the experiences and lessons learned on the path to understanding diversity in human interpretation and the ways to capture it as ground truth to enable machines to deal with such diversity.
Data Science with Human in the Loop @Faculty of Science #Leiden UniversityLora Aroyo
Software systems are becoming ever more intelligent and more useful, but the way we interact with these machines too often reveals that they don’t actually understand people. Knowledge Representation and Semantic Web focus on the scientific challenges involved in providing human knowledge in machine-readable form. However, we observe that various types of human knowledge cannot yet be captured by machines, especially when dealing with wide ranges of real-world tasks and contexts. The key scientific challenge is to provide an approach to capturing human knowledge in a way that is scalable and adequate to real-world needs. Human Computation has begun to scientifically study how human intelligence at scale can be used to methodologically improve machine-based knowledge and data management. My research is focusing on understanding human computation for improving how machine-based systems can acquire, capture and harness human knowledge and thus become even more intelligent. In this talk I will show how the CrowdTruth framework (http://crowdtruth.org) facilitates data collection, processing and analytics of human computation knowledge.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:
Climate Impact of Software Testing at Nordic Testing DaysKari Kakkonen
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.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

2. The Web
the most used and one of the most transformative applications
in the history of computing, e.g. how the Social Web has
transformed the world's communication
!
approximately 10
more than 10
Social Web 2014, Lora Aroyo!
3. The Web
Great success as a technology,
it’s built on significant computing infrastructure,
but
as an entity surprisingly unstudied
Social Web 2014, Lora Aroyo!
4. • physical science: analytic discipline to find laws that
generate or explain observed phenomena
• CS is mainly synthetic: formalisms & algorithms are
created to support specific desired behaviors
• Web Science: web needs to be studied & understood
as a phenomenon but also to be engineered for future
growth and capabilities
Social Web 2014, Lora Aroyo!
Science & Engineering
5. Web is NOT a Thing
• it’s not a verb, or a noun
• it’s a performance, not
an object
• co-constructed with
society
• activity of individuals
who create interlinked
content that reflect &
reinforce the
interlinkedness of
society & social
interaction
... and a record of
that performance
Social Web 2014, Lora Aroyo!
7. eScience: Analysis of Data
Social Web 2014, Lora Aroyo!
• the automated or semi-automated extraction of
knowledge from massive volumes of data — it is a
lot, but it is not just a matter of volume
• 3 Vs of Big Data
• Volume: #of rows / object / bytes
• Variety: # of columns / dimensions / sources
• Velocity: # columns / bytes per unit time
• more Vs — Veracity: Can we trust this data?
8. Simple micro rules give rise to
complex macro phenomena
Social Web 2014, Lora Aroyo!
• at microscale an infrastructure of artificial languages and protocols:
a piece of engineering
• however, interaction of people creating, linking and consuming
information generates web's behavior as emergent properties at
macroscale
• properties require new analytic methods to be understood
• some properties are desirable and are to be engineered in, others
are undesirable and if possible engineered out
9. • software applications designed based on appropriate
technology (algorithm, design) and with envisioned
'social' construct
• usually tested in the small, testing microscale properties
• a macrosystem evolving from people using the
microsystem and interacting in often unpredicted ways, is
far more interesting and must be analyzed in different
ways
• macrosystems exhibit challenges that do not exist at
microscale
Social Web 2014, Lora Aroyo!
A new way of software
development
10. Example:
Evolution of Search Engines
1: techniques designed to rank documents
2: people were gaming to influence algorithms &
improve their search rank
3: adapt search technologies to defeat this influence
Social Web 2014, Lora Aroyo!
11. The Web Graph
• to understand the web, in good CS
tradition, we look at the graph
• nodes are web pages (HTML)
• edges are hypertext links
between nodes
• first analysis shows that in-degree
and out-degree follow power law
distribution => holds for large
samples
• this gave insight into the growth of
the web
Social Web 2014, Lora Aroyo!
12. The (Search) Algorithms
• the Web graph also as basis of
algorithms for search engines:
• PageRank and others
assume that inserting a
hyperlink symbolizes an
endorsement of authority of
the page linked to
Social Web 2014, Lora Aroyo!
13. According to Google
each day 20-25% of searches have not been seen before, i.e.
generate a new identifier
thus a new node in the graph
more than 20 million new links per day, 200 per second
!
do they follow the same power laws & growth models?

validating such models is hard
exponential growth of content
changes in number & power of servers

17. Leveraging recent advances in:
• Theories: about social motivations for creating, maintaining, dissolving & re-creating
links in multidimensional networks & about emergence of macro-structures
• Data: Semantic Web provides technological capability to capture, store, merge &
query relational metadata to more effectively understand & enable communities
• Methods: qualitative & quantitative for theoretically-grounded network predictions
• Computational infrastructure: Cloud computing & petascale applications are
critical to face the computational challenges in analyzing the data
Social Web 2014, Lora Aroyo!
18. Network
Analysis
• is about linking social actors, e.g.
systematically understanding
and identifying connections
• by using empirical data
• draws on graphic imagery
• relies on mathematical/
computational models
• Jacob Moreno - one of the
founders of social network
analysis; some of the earliest
graphical depictions of social
networks (1933)
Social Web 2014, Lora Aroyo!
19. Think Networks!
• everything is connected to everything else
• networks are pervasive - from the human brain
to the Internet to the economy to our group of
friends
• following underlying order and follow simple laws
• "new cartographers" are mapping networks in a
wide range of scientific disciplines
• social networks, corporations, and cells are more
similar than they are different
• new insights into the interconnected world
• new insights on robustness of the Internet, spread
of fads and viruses, even the future of democracy.

21. Networks:
another perspective :-)
• Social Networks: It’s not what you know,
it’s who you know
• Cognitive Social Networks: It’s not who
you know, it’s who they think you know.
• Knowledge Networks: It’s not what you
know, it’s what they think you know
Social Web 2014, Lora Aroyo!
24. Web Science is about
additionality
not the union of
disciplines, but
intersection
Social Web 2014, Lora Aroyo!
25. Society is Diverse
different parts of society have different objectives and hence incompatible
Web requirements, e.g. openness, security, transparency, privacy
Social Web 2014, Lora Aroyo!
26. • POWER DISTANCE:The extent to which power
is distributed equally within a society and the
degree that society accepts this distribution.
• UNCERTAINTY AVOIDANCE:The degree to
which individuals require set boundaries and
clear structures
• INDIVIDUALISM vs COLLECTIVISM:The degree
to which individuals base their actions on self-
interest versus the interests of the group.
• MASCULINITY vs FEMININITY:A measure of a
society's goal orientation
• TIME ORIENTATION:The degree to which a
society does or does not value long-term
commitments and respect for tradition.

36. Social Web 2014, Lora Aroyo!
The Age of OPEN Data
TRANSPARENCY VALUE ENGAGEMENT
• common standards for release of public data
• common terms for data where necessary
• licenses - CC variants
• exploitation & publication of distributed, decentralised information assets
44. Web Science Reflections
Is the Web changing faster than our ability to observe it?
How to measure or instrument the Web?
How to identify behaviors and patterns?
How to analyze the changing structure of the Web?
Social Web 2014, Lora Aroyo!
45. Big Bang:
Web Information
• the assumption of open exchange of information is
being imposed on the society
• is the Web, and its open access, open data, scientific &
creative commons offer a beneficial opportunity or
dangerous cul-de-sac?
Social Web 2014, Lora Aroyo!
46. Open Questions
• How is the world changing as other parts of society impose their
requirements on the Web?, e.g. current examples with SOTA/PIPA,ACTA
requirements for security and policing taking over free exchange of information,
unrestricted transfer of knowledge
• Are the public and open aspects of the Web a fundamental change in
society’s information processes, or just a temporary glitch?, e.g. are open
source, open access, open science & creative commons efficient alternatives to
free-based knowledge transfer?
Social Web 2014, Lora Aroyo!
47. Social Web 2014, Lora Aroyo!
Open Questions
• do we take Web for granted as provider of a free & unrestricted
information exchange?
• is Web Science the response to the pressure for the Web to change - to
respond to the issues of security, commerce, criminality & privacy?
• what is the challenge for Web science in explaining how the Web impacts
society?
