Ontologies dynamic networks of formally represented meaning1STIinnsbruck
This document discusses the concept of ontologies and their role in enabling the Semantic Web. It makes three key points:
1) Ontologies provide formal semantics that allow information to be machine-processable, but also define real-world semantics to link machine content to human meaning.
2) Ontologies should be viewed not as isolated theories but as dynamic networks that evolve through social processes to establish shared understanding between humans and systems.
3) For ontologies to effectively enable information sharing, they must be interwoven into a heterogeneous network that links local domain models and allows for overlapping conceptualizations.

Research seminar at the University of Brighton presenting the ARISE project.
Here's the abstract:
Augmented Reality (AR) has a range of affordances that resonate with learning theory. Reflecting the early stage of the technology however, much existing research into AR focuses on technical issues and is based on prototype systems not suitable for end user deployment.
This presentation gives an insight into experiences gained in the European ARiSE (Augmented Reality in School Environments) project, which aims to develop a robust and affordable AR teaching platform suitable for deployment in schools.
In order to evaluate the tabletop AR learning platform, three consecutive prototypes of educational applications were produced, each reflecting the evolving technological capabilities of the platform and addressing different pedagogical approaches. These ranged from process visualisation in a human biology setting based on behaviourist and cognitive approaches, through guided construction of chemical elements based on constructivist ideas, to knowledge creation through communication and negotiation of meaning around cultural heritage objects with peers from another country, based on theories of social learning. The first two applications have been evaluated in summer schools involving video observations and interviews with secondary school students from Romania, Latvia and Germany.
Preliminary results indicate a high acceptance rate for the AR learning platform amongst students. The main advantages were seen in the 3D visualisation capabilities and the haptic user interface, which led to increased motivation, better concentration during learning activities, and faster and more accurate understanding of the learning content. Balancing these positive results were technical and usability issues that had a negative impact on the learning process.
The document discusses the CoMETE Project, a course at the University of Evry that teaches students Mozilla technologies. It provides theoretical lessons and practical projects using Mozilla tools. In the first year, students found the open source projects well-structured and were able to immediately apply what they learned. Many felt participating in an open source project would help them find jobs. The project creates a partnership between Mozilla and the university to spread Mozilla technologies and help more students contribute to open source.

PolyCAFe
(a Polyphony-Based System for Collaboration
Analysis and Feedback Generation)
11 9 December 2010
12. Chat Conversations with Multiple
Participants
Multiple participants (≥3), conferencing style
Particular features – multiple, parallel discussion
chains !!!
There is a need for
Determining important utterances
Contributions of the participants
Degree of collaboration - inter-animation analysis
12 9 December 2010
13. Example: CSCL assignment
Students had to debate in chat sessions in
groups ranging from 3 to 8
In the first part of the conversation, each student
had to defend a technology by presenting its
features and advantages and criticize the others
by invoking their flaws and drawbacks
In the final part of the chat, they had to discuss on
how they could integrate all these technologies in
a single online collaboration platform

Cognitive Socio-cultural
Newell, Simon Vygotsky, Bakhtin
“Knowledge is in the head” “Knowledge is in the community”
Artificial Intelligence, Theory of Activity,
Natural Language Processing Collaborative systems
Ontologies Folksonomies
Semantic Web Social Web (Web2.0)
Intelligent Tutoring Systems Computer-Supported Collaborative Learning
19 9 December 2010
20. Computer Supported Collaborative
Learning
A new paradigm in learning with computers
(Koshmann, 1999):
Knowledge is constructed socially (Vygotsky)
Induced by the spread of forums, chats, blogs,
wikis and folksonomies learning in (on-line)
virtual teams and/or communities
20 9 December 2010
21. Dialogism – Mikhail Bakhtin
• Basis for the CSCL paradigm (Koschman,
1999)
• “… Any true understanding is dialogic in
nature” (Voloshinov-Bakhtin, 1973)
• Opposed to de Saussure ideas, which are the
basis for Natural Language Processing
Polyphony
Inter-animation of voices
21 9 December 2010
22. The Polyphonic Model of CSCL
(Trausan-Matu, Stahl and Zemel, 2005,
http://mathforum.org/wikis/uploads/Stefan_Interanimation.doc)
A polyphony of voices characterizes any linguistic phenomenon
(Bakhtin) including CSCL chats
Inter-animation (Bakhtin, Wegerif) may be detected in
interactions and it may be used for analyzing collaboration and
assessing learners
Integrating NLP techniques with polyphony identification and
Social Network Analysis may provide a way for analyzing the
contributions of each participant and their collaboration.
Inter-animation and polyphony appears also in non-verbal
interactions
Consider threads (voices which last) rather than analyzing pairs
of utterances
22 9 December 2010
25. Words, voices and threads
Different positions assigned to participants – different
voices
Additional voices – frequent concepts – repeated
words become voices, stronger or weaker
Voices continue and influence each other through
explicit or implicit links.
Voices correspond to chains or threads of utterances:
repeated words
lexical chains
co-references
reasoning or argumentation
rhetorical schemas
25 9 December 2010
26. Analysis Units in the Polyphonic
Model
Words
Utterances
Pairs of utterances (links)
Threads
Voices
Participants
26 9 December 2010
27. Units of Interaction
Echoes of voices
Polyphonic-contrapuntal weaving
Inter-animation
Links between utterances and between words
Links may be:
implicit
explicit
27 9 December 2010
36. Social Network Analysis
• Degree
• Centrality
– Closeness
– Graph
– Eigen Value
• User Ranking
– Google Page Ranking
36 9 December 2010
37. Utterance evaluation
Social • Degree
• Semantic similarity
Qualitative • Predefined topics
• Overall discourse
• NLP Pipe
Quantitative • No of occurrences
mark(u) = ∑ words ( stem ) × (1 + log( no _ occurences )) × emphasis (u ) × social (u )
length
remaining
emphasis (u ) = Sim (u , whole _ document ) × Sim (u , predefined _ keywords )
social (u ) = ∏ (1 + log( f (u ))
all social factors f
( quantitative and qualitative )
37 9 December 2010
38. Collaboration (1)
• Utterance graph
– Explicit links – Attenuation
– Implicit links – Trust
• Social cohesion
• Quantitative collaboration
∑ all links l
with different speakers
attenuatio n(l) * trust(l)
quantitati ve collaborat ion =
total number of links (implicit/ explicit)
38 9 December 2010
39. Collaboration (2)
Qualitative - Gain based collaboration =
ECHO
Personal – individual knowledge building
Links to previous utterances with same speaker
Collaborative – collaborative knowledge
building
Links to previous utterances with different speaker
personal gain(u) = ∑ ((mark(v) + gain(v) ) * similarity(u, v) * attenuation(l) * trust(l))
link l exists between u and v,
v is an earlier utterance and
u and v have same speaker
collaborative gain(u) = ∑ ((mark(v) + gain(v) ) * similarity(u, v) * attenuatio n(l) * trust(l))
link l exists between u and v,
v is an earlier utterance and
u and v have different speakers

41. Services & Widgets
PolyCAFe is an online platform:
Web services (Java and PHP-based)
Web widgets using W3C Widgets1.0 standard
The widgets can be integrated into any web
platform that has a W3C widget container
(e.g. Wookie)
There are services for maintenance tasks and
analysis tasks (process discussion, search,
etc.)
The widgets have been deployed in Elgg
(PLE)
41 9 December 2010
49. Validation Experiment 1.0
• Validation of PolyCAFe 1.0
– 9x students
– 5x tutors, 1x teacher
• Two chats with 4-5 students in a team
• All the students used PolyCAFe for the first time
• Only two tutors have previously used the system
• Students used the automatic feedback to get
insight about their discussion
• Tutors used PolyCAFe to offer manual feedback
49 9 December 2010
50. Validation Results – Tutors
The tutors validated all the instruments with
suggestions to change part of them
Quiz with 35 questions – all of them passed with an
average score between 3.50-5.00 / 5.00
The system is relevant and useful for their
activity
The time for providing final feedback to the
students is definitively reduced (between 30-
50%)
The quality of the feedback is improved
50 9 December 2010
52. Validation Results – Students
The students have validated most of the
instruments
Quiz with 32 questions – 5 where not validated; all
others have scores over 3.66/5.00
In the focus group, they reported that several
misleads have been found using this widgets
These errors or misleads were reported to be
only minor without influencing the overall
feedback
It has been suggested to try and fix them in
order to gain the full trust of the users
52 9 December 2010
53. Validation Results – Students (2)
For example, the students did not validate:
“Overall, I believe that the support for my
learning PolyCAFe (Chat Analysis and
Feedback Service) provides is close enough
to the current support provided by humans. ”
Average = 3.11
Perc. agree = 33%
However, we do not want to provide a
substitute for human evaluation!
53 9 December 2010
55. Validation Results - Widgets

useful
Utterance feedback is useful 83% 100%
Participant feedback is useful 78% 100%
Search conversation is useful 61% 100%
55 9 December 2010
56. Validation Experiment 2.0
Validation of PolyCAFe 1.5
25x students in experimental group
10x students in control group
6x tutors in experimental group
2x 7 chats with 5 students in a team
Most of the students used PolyCAFe for the first time
All the tutors have previously used the system
Experiment is still under-way
Preliminary results are very encouraging: very high
correlation between ranking of participants by the system
and by the participants themselves
56 9 December 2010
57. Verification
Accuracy of system ranking of participants
Accuracy of grading utterances
Accuracy of determining implicit links,
collaboration areas, discussion threads
Accuracy for determining speech acts
Accuracy for determining Model of Inquiry classes
57 9 December 2010
59. Conclusions and Future Work
(PolyCAFe)
The system is working well
The system passed the validation with students
and tutors
The visualization widget proved to be the most
useful
The interface might be improved
59 9 December 2010
60. Transferability Issues
• Domain
– The topic of the conversation should be easily
solved using discussions, no graphics or formulas
• Language
– Need for the components of the NLP pipe
– Corpus for training the LSA
– Maybe, a domain ontology
• Activity
– Collaborative activity
– Teams of 4-15 students (in the current design)
60 9 December 2010
62. Learning Scenario
Learner just uses social networking web sites
He connects to friends and possible tutors

for crawling
66 9 December 2010
67. Search and Recommendations
Search
• Search algorithm based on PageRank R (v )
R(u ) = c ∑
• Folkrank - a user is important if he annotates important (v)
v∈B ( u ) N
resources with relevant (well ranked) tags.
• Fokrank works on a folksonomy - hypergraph - F=(V,E)
where V=U ∪R ∪T and E⊂UxRxT
Recommendation
• Uses clustering of resources, users and tags to
suggest relevant resources
67 9 December 2010
69. Using the Learning Services in a PLE
Search for Search for
resources users

70. Conclusions and Future Work
(Search and recommendations service)
We use social data to provide feedback for
learners
We offer relevant resources to the user from his
social network
We help learners to find peers or tutors
The work was embedded in Moodle/WebCT and
validated in Bucharest and Utrecht
We’re centralizing the results
