Moving image indexing perspectives
1. Concept-based retrieval
The second order of orders
(Weinberger, 2008)
© 3
• Analysis of the content instead of
the metadata
• Video segmentation
• Shot/sequence detection
• Key-frames extraction
• Low-level features such as object
motion, color, shape, texture,
loudness, power spectrum,
bandwidth, and pitch
• High-level features (e.g.,“finding
a picture of water” or “searching
for Mona Lisa Smile”).
• Automatic cast identification
“When combined, we find that content-based video retrieval incorporated into the
archive’s practice results in significant performance increases for shot retrieval and
for retrieving entire television programs. The time has come for audiovisual archives
to start accommodating content-based video retrieval methods into their daily
practice.” (Huurnink et al., 2012)

2. Content-based indexing (CBIR)

Crowdsourcing
• Spontaneus “indexing”
• Users as indexers
• Different backgrounds and
knowledge
• Lack of domain knowledge of
the user
• Lack of control
7
Nichesourcing
(De Boer et al, 2012; Accurator
project)
• Experts as annotators

Study: Understanding film scholars’ annotation behavior
• RQ: How do film scholars behave as moving image
indexers?
• Theoretical framework: Information behavior
– cognitive theory for interactive information retrieval (IIR) put
forward by Ingwersen (1992, 1996, 2001)
• Method: Pia Borlund’s simulated work tasks
All participants got 2 different film clips (1 control clip), 1 short movie
and selected 1 movie themselves for each task in randomized order (in
total 2 clips and 2 movies)
1. Context independent and system-free task
2. Context dependent and system-free task
3. Context and system dependent
4. System dependent, context not clear
9
Participants
• Participants: 10 film scholars from 5 universities
in Madrid:
– Autónoma de Madrid (Art History dept.)
– Camilo José Cela University (Communication Sciences
dept.)
– Carlos III (Audiovisual Communication dept.)
– Complutense (Audiovisual Communication dept.)
– Rey Juan Carlos (Communication Sciences dept.)
• Film scholars with 10 or more years of experience in
publishing, teaching, editorial activities, festival
commitees, etc. 10
Finding I. Annotation styles
1. Descriptive texts (Para-texts) *
– Narrative structure + critical texts
– Interpretative clues for the reader
2. Combination of Descriptive/Critical texts and Keywords
3. Keywords / Tags / Descriptors
4. Plot synopsis
*(Gérard Genette, after commented by Nico de Klerk and studied in a recent book
edited by Pellatt, 2013)
11
Finding II. Unit of analysis and indexing
granularity
1. What do I have to describe? Clips vs entire movies
2. Annotation for access vs annotation for scholars’ own
research –Describing and searching tasks differ (Fidel,
1997)
12
RDA: Rules for Archival Description (Turner, 2009)
Finding III. Attributes
Sound, music
Narrative, story, plot, characters
Genre, movement, country
Influences, relations
Cinematographic, formal, stylistic features
CONTEXT, historical information
13
Finding IV. Willingness to participate
• 9 of the 10 participants said “Yes” to a proposal to
contribute to Nichesourcing initiatives by a film archive,
1 said “No”
• 1 of the scholars saying yes, hesitated of the success of
such idea: “Access is not about indexing or ordering, but
about selection and education”
• Scholars suggested: clarity, easiness, reward (not
necessary economic, but in the form of input and
feedback on the use of their voluntary work)
• The scholar who said “No” was very much aware of the
need of Indexing knowledge for any annotation task
14
Recommendations for Nichesourcing
• Tags or keywords alone are not enough for supporting
Film scholarship, different annotation styles should be
supported and “mined”
• Indexing knowledge should not be required from
domain experts. Any annotation system for scholars
has to clearly guide the indexing process
• The purpose and use of the annotations has to be
stated clearly
• Scholars should be provided with films they are familiar
with or are interested in (this is already done in
projects such as Naturalia/Accurator).

Recommendations for Film archives
• Request scholars’ participation in
annotation activities
• Ask researchers to contribute with
their notes during research visits
• Provide digital tools for research,
both in situ and online
• Create events around annotation
practices (i.e. “Bird watching at
the museum”)
• Create online communities of
researchers (Martorell, Canet, Codina,
2014) 17

Understanding film scholars' annotation behavior

  • 1. Understanding film scholars’ annotation behavior: Supporting scholarship by enhancing online film annotations Liliana Melgar-Estrada PhD candidate in Information Sciences Universidad Carlos III de Madrid lmelgar@bib.uc3m.es Digital Humanities Benelux Conference June 12, 2014 1. Motivation and Research framework i. Context, motivation ii. PhD thesis overview iii. Background research: Perspectives in (moving) image indexing 2. Conceptual framework i. Crowdsourcing ii. Nichesourcing 3. Case study i. Research questions ii. Participants iii. Method iv. Findings and discussion 4. Conclusions
  • 2. PhD thesis in Information Science(s) Information behavior studies 2 Wilson's 1999 nested model of information behaviour “How and why can current indexing perspectives be used by film archives to support film scholarship. ”
  • 3. Context: Digital tools in film studies 3 Videana Visualizing Vertov (Ross et al., 2009)
  • 4. Indexing and annotating (moving) images Moving image indexing: time-based 4 © 1 Text indexing: based on words and characters © 2
  • 5. 5 Moving image indexing perspectives 1. Concept-based retrieval The second order of orders (Weinberger, 2008) © 3
  • 6. • Analysis of the content instead of the metadata • Video segmentation • Shot/sequence detection • Key-frames extraction • Low-level features such as object motion, color, shape, texture, loudness, power spectrum, bandwidth, and pitch • High-level features (e.g.,“finding a picture of water” or “searching for Mona Lisa Smile”). • Automatic cast identification “When combined, we find that content-based video retrieval incorporated into the archive’s practice results in significant performance increases for shot retrieval and for retrieving entire television programs. The time has come for audiovisual archives to start accommodating content-based video retrieval methods into their daily practice.” (Huurnink et al., 2012) 6 Moving image indexing perspectives 2. Content-based indexing (CBIR) © 4
  • 7. Crowdsourcing • Spontaneus “indexing” • Users as indexers • Different backgrounds and knowledge • Lack of domain knowledge of the user • Lack of control 7 Nichesourcing (De Boer et al, 2012; Accurator project) • Experts as annotators Moving image indexing perspectives 3. Crowdsourcing and Nichesourcing © 5 © 6
  • 8. Time-based crowdsourced annotations 8Geisler, 2012 Cinecast. La ligne du temp, BNF
  • 9. Study: Understanding film scholars’ annotation behavior • RQ: How do film scholars behave as moving image indexers? • Theoretical framework: Information behavior – cognitive theory for interactive information retrieval (IIR) put forward by Ingwersen (1992, 1996, 2001) • Method: Pia Borlund’s simulated work tasks All participants got 2 different film clips (1 control clip), 1 short movie and selected 1 movie themselves for each task in randomized order (in total 2 clips and 2 movies) 1. Context independent and system-free task 2. Context dependent and system-free task 3. Context and system dependent 4. System dependent, context not clear 9
  • 10. Participants • Participants: 10 film scholars from 5 universities in Madrid: – Autónoma de Madrid (Art History dept.) – Camilo José Cela University (Communication Sciences dept.) – Carlos III (Audiovisual Communication dept.) – Complutense (Audiovisual Communication dept.) – Rey Juan Carlos (Communication Sciences dept.) • Film scholars with 10 or more years of experience in publishing, teaching, editorial activities, festival commitees, etc. 10
  • 11. Finding I. Annotation styles 1. Descriptive texts (Para-texts) * – Narrative structure + critical texts – Interpretative clues for the reader 2. Combination of Descriptive/Critical texts and Keywords 3. Keywords / Tags / Descriptors 4. Plot synopsis *(Gérard Genette, after commented by Nico de Klerk and studied in a recent book edited by Pellatt, 2013) 11
  • 12. Finding II. Unit of analysis and indexing granularity 1. What do I have to describe? Clips vs entire movies 2. Annotation for access vs annotation for scholars’ own research –Describing and searching tasks differ (Fidel, 1997) 12 RDA: Rules for Archival Description (Turner, 2009)
  • 13. Finding III. Attributes Sound, music Narrative, story, plot, characters Genre, movement, country Influences, relations Cinematographic, formal, stylistic features CONTEXT, historical information 13
  • 14. Finding IV. Willingness to participate • 9 of the 10 participants said “Yes” to a proposal to contribute to Nichesourcing initiatives by a film archive, 1 said “No” • 1 of the scholars saying yes, hesitated of the success of such idea: “Access is not about indexing or ordering, but about selection and education” • Scholars suggested: clarity, easiness, reward (not necessary economic, but in the form of input and feedback on the use of their voluntary work) • The scholar who said “No” was very much aware of the need of Indexing knowledge for any annotation task 14
  • 15. Recommendations for Nichesourcing • Tags or keywords alone are not enough for supporting Film scholarship, different annotation styles should be supported and “mined” • Indexing knowledge should not be required from domain experts. Any annotation system for scholars has to clearly guide the indexing process • The purpose and use of the annotations has to be stated clearly • Scholars should be provided with films they are familiar with or are interested in (this is already done in projects such as Naturalia/Accurator). 15

  • 17. Recommendations for Film archives • Request scholars’ participation in annotation activities • Ask researchers to contribute with their notes during research visits • Provide digital tools for research, both in situ and online • Create events around annotation practices (i.e. “Bird watching at the museum”) • Create online communities of researchers (Martorell, Canet, Codina, 2014) 17 © 9
