Mauri Kaipainen Multiperspective explorability of tag spaces Mauri Kaipainen, Katrin Niglas, Peeter Normak, Jaagup Kippar
2
Mauri Kaipainen KERG Perspectives to Web 2.0 cognitive social design
3
Mauri Kaipainen Competences from: Cognitive science Computer science Education Statistics
4
Mauri Kaipainen Core issue: Ontologies of Web 2.0? How to make sense of the conceptual polyphony of everyone’s democratic Web 2.0? Report of work in progress.
5
Mauri Kaipainen Focus: Collaborative tagging Examples: Flickr YouTube Del.icio.us CiteULike =>Collaborative sensemaking = ’definition of conceptualization’
6
Mauri Kaipainen Tag space The accumulation of tags in a collaborative tagging system as shared conceptual space.
7
Mauri Kaipainen Tag space as ontology ”An ontology is a specification of a conceptualization” (Gruber 1993) What dimensions define the tag space?
8
Mauri Kaipainen Tag space as ontological space (ontospace)
9
Mauri Kaipainen Soft ontology Open ended Non-hierarchical (flat) Allows constant redefinition (perspectives) Elaboration of Aviles...Kaipainen et al. (2003)
10
Mauri Kaipainen Soft ontology as matrix Add tags = ontodimensions Explore! Give your weights to tags = perspective
11
Mauri Kaipainen Perspective to ontospace
12
Mauri Kaipainen Perspective visualization Visualization of ontospace from chosen perspective with: Multidimensional Scaling (MDS, Kruskal & Wish 1978) Similarity clustering
13
Mauri Kaipainen Multi-Perspective Exploration - Why? Go ’beyond the information given’ (Bruner 1973)! Hands-on ontology! Recognizing different views to the ontospace Explicate and analyse one’s own perspectives, premises Share perspectives (Compare to photo angles!) Ecology, immersion in conceptual world! (Ulric Neisser in the era... => Games)
14
Mauri Kaipainen Exploration as knowledge building Neisser’s perceptual cycle (1976) emphasizes the systemic nature of cognitive ecology
15
Mauri Kaipainen Perceptual cycles and shared ontology as object of exploration Shared ontology
16
Mauri Kaipainen Characteristics of the system Ecology, complex system Iterative, continuous Knowledge building –Social: Shared domain –Individual: Private perspectives
17
Mauri Kaipainen Prototype of exploration tool: Perspective by sliders Slider interface to explore perspectives => Similarity clustering
18
Mauri Kaipainen Exploration tool: Content item characterized
19
Mauri Kaipainen Soft search Consider best hit it with respect to the next-best ones Why this result? What if? Try different perspectives => Iterative feedback to schema!
20
Mauri Kaipainen Soft distinctions Explore the effect of taking into account another ontodimension Better distinction?
21
Mauri Kaipainen Summary: Hands on ontology! Going ”beyond the information given” Bruner (1973) Allows hands on exploration of ontology Supports individual knowledge building
22
Mauri Kaipainen Summary: Sharing ontology Ontospace and the exploration tool can be built into online applications! Individual perspectives made shareable –Understanding the other –Elaborating common concepts
23
Mauri Kaipainen Conclusions How to make sense of conceptual polyphony of ’democratic’ Web 2.0 concepts? a) Experts’ top down fixed ontology definitions, or b) Democratic soft ontologies and multiperspective exploration
24
Mauri Kaipainen Conclusions Proposed Interaction with ontospace as a means of cognitive-social knowledge building Repurposing a statistical method to allow real-time multi-perspective exploration of ontospaces Transition from sharing a domain to sharing perspectives
25
Mauri Kaipainen Discussion Multiperspective exploration: ’Immersion’ to concretized virtual conceptual spaces? Exploration ≈ playing around => game-like approach to complex information domains
26
Mauri Kaipainen Discussion Other application areas besides collaborative tagging Methodology: Mixed qualitative- quantitative methods (Niglas & Kaipainen in press) Political space Geotagging (Taggin’ Tallinn) All sensemaking of complex domains!
