acm sigir98 workshop multimedia indexing retrieval note deadline initial submission extended june 19 acm sigir 98 post conference workshop multimedia indexing retrieval melbourne australia august 28 1998 call participation background workshop focus required functionality techniques evaluation criteria multimedia information retrieval systems researchers investigating contentbased retrieval nontext sources images audio video initially focus efforts content analysis retrieval techniques tailored specific media recently researchers started combine attributes various media goal multimedia ir systems handle general queries find outdoor pictures video clinton gore discussing environmental issues answering queries requires intelligent exploitation text speech visual content multimedia ir broad area covering infrastructure issues e g efficient storage criteria networking clientserver models intelligent content analysis retrieval since oneday workshop chosen three focus areas intelligent analysis retrieval area workshop first focus workshop integrating information various media sources order handle multimodal queries large diverse databases example collection would www cases query may decomposed set media queries involving different indexing scheme interaction various media sources occur context e g text accompanying pictures audio accompanying video special interest interaction exploited content analysis retrieval phases second focus deals examples research using content organization multimedia information semantic classes users pose expect retrieval provide answers semantic questions practice difficult achieve building structures encode semantic information fairly domain independent robust manner extremely difficult quick review computer vision research last years points difficulty many cases image content used conjunction user interaction domain specificity retrieve semantically meaningful information however clear retrieval similarity visual attributes used arbitrarily provide semantically meaningful information example search red flower color red heterogeneous database expected yeild meaningful results hand retrieval red flowers database flowers achieved using color context therefore examples research using content organization multimedia information semantic classes discussed many systems particularly image video based ones require example picture used query alternatively user may required draw picture may unrealistic expect example image always available thus would useful find ways generating new queries nlp techniques combined computer vision techniques generate queries multimodal retrieval techniques combined create queries suitable image video audio retrieval general question create realistic queries realistic systems third focus workshop evaluation techniques multimedia retrieval currently researchers using standard evaluation measures defined text documents need extended modified multimedia documents also high degree subjectivity involved needs addressed focus following specific topics content analysis retrieval various media text images video audio interaction modalities e g text images indexing retrieval effective user interfaces permitting query refinement etc evaluation methodologies multimedia information found researchers pay insufficient attention techniques relevance ranking multimodal query formation decomposition logic formalisms multimodal queries indexing retrieval scanned documents e g extracting text images word spotting retrieval technique handwritten printed documents testbeds evaluating multimodal retrieval would nice resource sharing since annotating coming good query set difficult participation two types participation expected interested making presentation
