Invited Talk OAGM Workshop Salzburg, May 2015dermotte
There is a gap between a user's information need and the queries they submit, known as the "intention gap". Bridging this gap is challenging due to the difficulty of translating intentions into search queries. Researchers have studied user intentions in various contexts like search, media production and sharing. However, fully understanding intentions is difficult as people have trouble expressing their own intentions and judging those of others. Future work should develop new techniques to relate content-based image retrieval to user intentions and take an interdisciplinary approach to better model intentions across domains.

UXPA 2023: UX Fracking: Using Mixed Methods to Extract Hidden InsightsUXPA International
Users do not always accurately describe what they mean or feel. There are many reasons for this, ranging from politeness to poor introspection, to lack of sufficient technical vocabulary. Fortunately, UX researchers have tools in their trade to deduce what was really meant. We call this UX Fracking, a mixed methods approach that is optimized for extracting hidden user insights. We will illustrate the dangers of inadequate, superficial research, and how this may lead to outcomes incapable of addressing the users’ core issues. We will explore ways to avoid these pitfalls by leveraging mixed research methods to test hypotheses about the users’ intent and needs. This starts with a thorough understanding of who the user is, their goals, and how they work today, to an approach that combines surveys, interviews, and comment analysis with behavioral observation, and finally, validating the newly discovered user insights with the users themselves.

This document summarizes the LIRE (Library for Content Based Image Retrieval) framework. It describes LIRE as a Java-based CBIR library built on Lucene that provides easy indexing and searching of image features. Key points include that it has a modular feature architecture, supports fast linear and sub-linear search through hashing techniques, and includes tools for parallel indexing and intermediate data formats. The document also briefly discusses integrating LIRE with Apache Solr and future work plans.
This document summarizes an exploratory study on user intentions for video production. The study aimed to determine if a taxonomy could be developed to classify intentions, and to test current approaches. 20 participants were interviewed about 48 video recording situations. The situations were clustered into categories including preservation, sharing, affection, functional, and technical interest. Nearly all videos were intended for sharing, and most instances fit into multiple categories, suggesting current taxonomies are insufficient and classes are not disjoint for video production intentions. Future work is needed using larger and more varied datasets.

Callisto: Content Based Tag Recommendation for Imagesdermotte
Callisto is a tool that provides ranked tag recommendations for images based on their visual content and any start tags provided. It uses two models: 1) NCP, which bases suggestions on visual features in the image, and 2) a statistical model that analyzes tag co-occurrence. NCP often suggests tags highly related to visual features present in an image and does not suggest tags for features missing from the image. Callisto demonstrates this behavior through examples, showing it can provide different, visually-relevant suggestions for the same start tag depending on the image's actual visual content.
This document provides an overview of visual information retrieval and content-based image retrieval. It discusses the motivation for these topics due to the large number of digital images and videos now available. Various low-level image features that can be extracted for content-based image retrieval are described, including color histograms, dominant colors, color distribution, and color correlograms. The benefits and disadvantages of different features are also outlined. The goal is to reduce images to feature vectors for efficient similarity comparison and retrieval.
Using Visual Features to Improve Tag Suggestions in Image Sharing Sites :: pr...dermotte
The document discusses using visual features to improve tag suggestions for images on sharing sites. It presents the motivation for improving tagging rates, as only 20-25% of images are currently tagged on sites like Flickr despite the obvious benefits. The authors propose an architecture to focus on the annotation process by using visual features to reduce the effort required for users to tag images. They provide an overview of the current state of their work and preliminary conclusions.
This document discusses power laws, Zipf's law, and Pareto distributions. It explains that these distributions emerge when human behavior and decisions are involved. While the theories behind these distributions are well-established, there are also practical questions around how to detect and utilize them, such as how to identify content that may become popular and optimize websites, videos, and other resources accordingly. The document concludes that these distributions are real phenomena but the exact mechanisms behind why they occur are still not fully understood.
This document analyzes aspects of broad folksonomies based on a sample of over 800,000 bookmarks from Delicious. It finds that:
1) The frequency-rank distribution of co-occurring tags follows a power law for around 80% of tags analyzed.
2) When analyzing resource-based and user-based tagging characteristics, only around 18-13% of tags respectively followed a power law distribution, indicating folksonomies have a more complex underlying structure.
3) Tags provide added value for retrieval over title alone, though precision and recall were mostly below 0.5, showing tags are not redundant but current usage may not optimize retrieval performance.

● Definition of tasks reflecting different types of
goals
o Interviews with experts using image search
o Note: Verification of relevance of tasks needed
● Presentation of goals to users in a study
o Recording of search behavior
o Analysis of possible features for classification
23
24. Study setup
http://www.uni-klu.ac.at
● Taxonomy of Broder / Rose & Levinson
● 10 tasks from different classes
o Find picture expressing joy
o Find picture of the Eiffel Tower
o Find picture taken with a Canon IXUS 980 IS
o Find out how to tie a tie
o …
24
25. Findings
http://www.uni-klu.ac.at
● Revised taxonomy needed
● Classification difficult …
o where do session start and end?
o fuzzy transition between goals?
o Dependencies between goals, subgoals etc.?
● Classification prototype
o Rule based
o Adapting results view
25
26. Taxonomy development
http://www.uni-klu.ac.at
● Several additional studies
o Expert & non expert users
● Revised taxonomy
● Feature selection for classification

27. Agenda
http://www.uni-klu.ac.at
● Motivation & Introduction
● User goals in text retrieval
● User goals in digital photo retrieval
● User goals & intentions in media production
● Outlook

28. Intentions in Media
Production http://www.uni-klu.ac.at
● Annotation tool for digital photos
o done by two amateur photographers
● Two different roles
o Creator
o Consumer
● Study:
1. How do users get along with the UI
2. How do users get along with intentions for
annotation
28
30. iPan preliminary Results
http://www.uni-klu.ac.at
● Tool tested in photographers user group
o 2 extreme types: intentional photos and non-
intentional photos
o Maybe artists, who want to hide intentions?
● Interviews have been rather discouraging
o Mainly no intention to use such a tool
o No understanding for “intentional photography”
o One possible user => more like storytelling

31. Ongoing work …
http://www.uni-klu.ac.at
● Annotation tool based on intentions
● Taxonomy of goals in media production
● Investigation for other media

● Motivation & Introduction
● User goals in text retrieval
● User goals in digital photo retrieval
● User goals & intentions in media production
● Outlook

33. Users in a “near time” MMIS
http://www.uni-klu.ac.at
● Assume there is a big “Ironman” event
o sequence of
• 3.86 km of swimming,
• 180.2 km of biking and
• 42.195 km of running
o like Klagenfurt in 2007:
• 2,400 participants with support team (3-4 people)
• 2,000 volunteers
• 100,000 visitors
• 6 moderators & DJs / 3 video walls
• event lasted end to end about 17 hours
33
34. Users in a “near time” MMIS
http://www.uni-klu.ac.at
● Users have different roles
o Participants, support, guards, journalists …
● Users have different intentions
o I want to track athlete XY
o I want to track the lead
o I want to follow events
● User participate in a
“social MMIS”
34
35. Intentions in a “near time” MMIS
http://www.uni-klu.ac.at
● User intentions can be made explicit
o Classification, user feedback, context, etc.
● Intentions & goals can be leveraged to enhance
retrieval and visualization of content
o Relevance function (cp. popularity, 80:20)
o Abstraction & summarization
o Pro-active distribution
35
36. Summary & Conclusion
http://www.uni-klu.ac.at
User intentions
● … have not yet been explored in MIR & MMIS
● … may help bridging the semantic gap (from the
other side)
● … may help dealing with the “long tail”

… for your time
and: I’d be happy to discuss
the whole thing
