The document discusses new trends in television involving integrating TV and the web. It describes how TV content is increasingly being delivered over the web and how web content is being integrated into the TV experience. It also discusses concepts of social TV, which aims to connect the TV experience with social networks, and semantic TV, which adds formal semantic descriptions to TV programs and schedules to enable new methods of filtering and augmenting TV content. The NoTube project is working to integrate TV and the web using semantics.
This is a "why" overview of social networking. It gets people thinking of why they may want to rather than "how" to. I plan on following up with a how to. Let me know what you think.
Social Networking Sites are Changing the Face of CommuncationIBMTelecom
Social networking Web sites and services have become primary communication media for a new generation of digitally aware consumers, competing with traditional telecommunications for "share of voice." To compete effectively over the long term, CSPs will need to take bold, significant steps to embrace the emerging broader definition of communications.

Book Formatting: Quality Control Checks for DesignersConfidence Ago
This presentation was made to help designers who work in publishing houses or format books for printing ensure quality.
Quality control is vital to every industry. This is why every department in a company need create a method they use in ensuring quality. This, perhaps, will not only improve the quality of products and bring errors to the barest minimum, but take it to a near perfect finish.
It is beyond a moot point that a good book will somewhat be judged by its cover, but the content of the book remains king. No matter how beautiful the cover, if the quality of writing or presentation is off, that will be a reason for readers not to come back to the book or recommend it.
So, this presentation points designers to some important things that may be missed by an editor that they could eventually discover and call the attention of the editor.
Transforming Brand Perception and Boosting Profitabilityaaryangarg12
In today's digital era, the dynamics of brand perception, consumer behavior, and profitability have been profoundly reshaped by the synergy of branding, social media, and website design. This research paper investigates the transformative power of these elements in influencing how individuals perceive brands and products and how this transformation can be harnessed to drive sales and profitability for businesses.
Through an exploration of brand psychology and consumer behavior, this study sheds light on the intricate ways in which effective branding strategies, strategic social media engagement, and user-centric website design contribute to altering consumers' perceptions. We delve into the principles that underlie successful brand transformations, examining how visual identity, messaging, and storytelling can captivate and resonate with target audiences.
Methodologically, this research employs a comprehensive approach, combining qualitative and quantitative analyses. Real-world case studies illustrate the impact of branding, social media campaigns, and website redesigns on consumer perception, sales figures, and profitability. We assess the various metrics, including brand awareness, customer engagement, conversion rates, and revenue growth, to measure the effectiveness of these strategies.
The results underscore the pivotal role of cohesive branding, social media influence, and website usability in shaping positive brand perceptions, influencing consumer decisions, and ultimately bolstering sales and profitability. This paper provides actionable insights and strategic recommendations for businesses seeking to leverage branding, social media, and website design as potent tools to enhance their market position and financial success.

10. State of the art in TV
• TV content shifting to the Web as delivery
platform
– An explosion in available content at any time
• Web content shifting to the TV as
augmentation of the TV experience
– An explosion in additional content at any time
10 New trends in television: social and semantic
11. Limitations of today‘s TV
• Too much content in one place
– How to find what you want to watch? Sort
between live TV, TV on demand, archives, video
portals and P2P-TV
• Too much functionality at any one time
– The whole Internet while you watch TV. But what
do viewers really want to be able to do
additionally (parallel) to watching TV?
11 New trends in television: social and semantic
12. Social TV
• Integrate the TV experience with the so-called
Social Web
– Who are my friends and what do they watch?
– What do my friends like -> maybe I‘d like it too
– Where are my friends now -> connect via the
shared TV experience
• Key goal for social TV
– Enhance my TV experience through my friends‘ TV
experience

13. Semantic TV
• Add formal semantic descriptions for
– TV programmes
– TV schedules (EPGs)
• Link those descriptions to other semantic data
on the Web, cf. Linked Data
• Two key use cases for semantic TV:
– Filtering of TV content -> personalisation,
recommendation
– Augmentation of TV content with Web data

19. The Semantic Web
The vision of what was termed the “Semantic Web“ first came to public
attention through an article in Scientific American in May 2001.
“The Semantic Web is not a separate
Web but an extension of the current one,
in which information is given well-defined
meaning, better enabling computers and
people to work in cooperation.”*

20. HTML
HTML was too limited for Web documents – it is purely a presentation
format. The tags in HTML have no meaning outside how content should be
rendered in the browser, and so the meaning of the content must be
interpreted by a human, hence excluding any possibility of machine
processing.

The core idea of XML – Extensible Markup Language – is to provide for
definitions of markup which allows self-describing tags, i.e. tags which
describe the meaning of the content they mark up rather than its
presentation
21 New trends in television: social and semantic
22. RDF
RDF provides a graph structure for making statements about things.
Individual things, and not just files, are given an URI identifier.
This is where the Semantic Web begins.

22 New trends in television: social and semantic
23. RDFS
RDF Schema begins to formalise the meaning of things spoken about in
RDF on the basis of computational logic. RDFS permits simple ontologies
(models about concepts and their properties) to be defined, which can be
used to conclude new knowledge.

24. OWL
OWL broadens the possible expressivity of the ontology. This makes
richer models of knowledge about things possible, but at the cost of those
models being more complex for a computer to process.

25. SPARQL
The final block of the Semantic Web that we will cover in this introduction is
SPARQL, the query language for semantic data using the RDF data model
(which includes OWL).

26. Semantic Web principles
• Every concept can be identified with URIs
• Resources and relationships are typed semantically
• Partial information is acceptable
• Absolute truth is not necessary
• Evolution as a development principle
26 New trends in television: social and semantic
27. Linked Data principles
• Use URIs as names of things
• Use HTTP URIs so that people can look up those names
• When someone looks up an URI, provide useful information
• Include links to other URIs, so that they can discover more things
27 New trends in television: social and semantic
28. Semantic Web vs Linked Data
“In contrast to the full-fledged Semantic Web vision, linked
data is mainly about publishing structured data in RDF using
URIs rather than focusing on the ontological level or
inference. This simplification - just as the Web simplified the
established academic approaches of Hypertext systems -
lowers the entry barrier for data providers, hence fosters a
widespread adoption.”

37. (2) Semantic annotation for TV
• What can we annotate in TV?
– The program schedule
– The TV program
– TV program segments
• How can we annotate TV?
– Feature description (low level, analysis based)
– Metadata (date, creator, legal notice)
– Content description (title, summary, genre,
concepts)
37 New trends in television: social and semantic
38. Why have metadata?

have been the place
where the need for
accurate
documentation first
arose.
38 New trends in television: social and semantic
39. Broadcast metadata
• Data about data
– All digital resources (A/V, scripts, contracts, reports, pictures, etc.) are
data
– Metadata is created at all stages in broadcasting from commissioning
to playout
• Three main categories
– Administrative metadata
• Replacing project and asset management paperwork
– Technical metadata
• Format, processing, identification, location, database, network
– Descriptive metadata
• All asset related information, human readable

41 New trends in television: social and semantic
42. EPG data
• An EPG is composed of two parts: content descriptions and
broadcast description
• Content descriptions contain static data about television
programmes such as a brand name (e.g. EastEnders),
description or plot summary, type of programme, (e.g. series,
movie, news), genre(s) (e.g. drama) actors, directors,
recording data, etc.
• Broadcast description is expressed by variable data, such as
channel (e.g. BBC ONE), format (e.g. 16:9) and broadcast
media (e.g. digital television)
42 New trends in television: social and semantic
43. TVAnytime (1/2)
• Unique document structure
– Program description
– Program location
– Program segmentation
– User description & personalisation
– System aspects
– Content rights
43 New trends in television: social and semantic
44. TVAnytime (2/2)
• Advantages of TV-Anytime
– It is network and middleware independent
– Supports related material, segmentation, locators, group
information etc.
• Applications of TV-Anytime
– ARIB
– DVB (MHP, DVB GBS, DVB IPI, DVB CBMS)
– Asian User Groups, Korea
– US’ Consumer Electronic Association
– HbbTV

46. Other models in use
• egtaMETA - a unique metadata exchange schema dedicated
for the exchange of ads between ads agencies and
broadcasters. NoTube was an early tester of the schema in its
personalised advertisements use case.
• BMF – an abstract semantic model designed for metadata
exchange in the professional media production domain. ARD
in Germany is starting to use BMF.
• Presto Space – format generated by the project of the same
name to provide for digital preservation of audiovisual
collections. Used by NoTube partner RAI.

53. Concept extraction
• NLP tools identify named entities in text and attach
an unique identifier to them

• Recommender strategy
– Collaborative recommendation
• You share interests with your friends
• Statistical analysis: what content is liked/watched
quantitively more by others with similar interests/history
– Content-based recommendation
• An interest in X means a potential interest in Y
• Pattern-based analysis: what content has related concepts
to the content liked/watched by you
– Hybrid recommendation
• Best of both!
