Call for Papers
ACM Multimedia 2009 Workshop
Searching Spontaneous Conversational Speech (SSCS 2009)
October 23, 2009
Beijing, China

Multimedia content often contains spoken audio as a key component. Although
speech is generally acknowledged as the quintessential carrier of semantic
information, spoken audio remains underexploited by multimedia retrieval
systems. In particular, the potential of speech technology to improve
information access has not yet been successfully extended beyond multimedia
content containing scripted speech, such as broadcast news. The SSCS 2009
workshop is dedicated to fostering search research based on speech
technology as it expands into spoken content domains involving non-scripted,
less-highly conventionalized, conversational speech characterized by wide
variability of speaking styles and recording conditions. Such domains
include podcasts, video diaries, lifelogs, meetings, call center recordings,
social video networks, Web TV, conversational broadcast, lectures,
discussions, debates, interviews and cultural heritage archives. This year
we are setting a particular focus on the user and the use of speech
techniques and technology in real-life multimedia access systems and have
chosen the theme "Speech technology in the multimedia access framework."

The development of robust, scalable, affordable approaches for accessing
multimedia collections with a spoken component requires the sustained
collaboration of researchers in the areas of speech recognition, audio
processing, multimedia analysis and information retrieval. Motivated by the
aim of providing a forum where these disciplines can engage in productive
interaction and exchange, Searching Spontaneous Conversational Speech (SSCS)
workshops were held in conjunction with SIGIR 2007 in Amsterdam and with
SIGIR 2008 in Singapore. The SSCS workshop series continues with SSCS 2009
held in conjunction with ACM Multimedia 2009 in Beijing. This year the
workshop will focus on addressing the research challenges that were
identified during SSCS 2008: Integration, Interface/Interaction,
Scale/Scope, and Community.

We welcome contributions on a range of trans-disciplinary issues related to
these research challenges, including:

-Information retrieval techniques based on speech analysis (e.g., applied to
speech recognition lattices)
-Search effectiveness (e.g., evidence combination, query/document expansion)
-Self-improving systems (e.g., unsupervised adaptation, recursive metadata
-Exploitation of audio analysis (e.g., speaker emotional state, speaker
characteristics, speaking style)
-Integration of higher-level semantics, including cross-modal concept detection
-Combination of indexing features from video, text and speech

-Surrogates for representation or browsing of spoken content
-Intelligent playback: exploiting semantics in the media player
-Relevance intervals: determining the boundaries of query-related media segments
-Cross-media linking and link visualization deploying speech transcripts

-Large-scale speech indexing approaches (e.g., collection size, search speed)
-Dealing with collections containing multiple languages
-Affordable, light-weight solutions for small collections, i.e., for the
long tail

-Stakeholder participation in design and realization of real world applications
-Exploiting user contributions (e.g., tags, ratings, comments, corrections,
usage information, community structure)

Contributions for oral presentations (8-10 pages) poster presentations (2
pages), demonstration descriptions (2 pages) and position papers for
selection of panel members (2 pages) will be accepted. Further information
including submission guidelines is available on the workshop website:
