Fr: Gerry McKiernan Re: Reactive E-Journals I am greatly interested in identifying additional e-journals that provide an opportunity to comment on a published article within the ejournal either as an annotation to segments of the article or as a separate component of the e-journal such as found within _Earth Interactions_ (EI) [ http://EarthInteractions.org/ ] _Earth Interactions_ " is an electronic journal dealing with the interactions between the lithosphere, hydrosphere, atmosphere, and biosphere in the context of global issues or global change. It exploits the capabilities of electronic communications technology and provides its authors the opportunity to use animations and other visualization techniques that traditional publications cannot accommodate." In addition to offering Embedded Multimedia, _Earth Interactions_ also provides a moderated threaded discussion section that allows interaction among authors and readers of both EI articles and preprint manuscripts. For details, see http://eij.gsfc.nasa.gov/E-JOURNAL/react/ As Always, Any and All contributions, queries, critiques, comments, questions, concerns, etc., etc. regarding this post are Most Welcome.

Fr: Steve Minton Re: Reactive E-Journals As the former executive editor for the Journal of Artificial Intelligence Research (JAIR) (see http://www.jair.org/), I have a couple of comments regarding both reactive e-journals and multi-media content. JAIR has been around since early in 1993, so we have a fair amount of experience at this point. The journal is highly regarded, and we attract a large number of submissions. As for reactive e-journals, we've twice created facilities where readers could comment and ask questions about articles. Neither attempt was a success. To quote from an article about JAIR I recently co-authored with Mike Wellman: >Experiments do not always work. JAIR has tried several mechanisms for >readers to post comments and questions about articles, much success. >When the journal was first established, we asked readers to post >questions and comments to the USENET newsgroup comp.ai and to preface >the subject line of these posts with "JAIR:". In fact, a few >interesting discussions appeared there, such as a debate about bias in >machine learning triggered by a JAIR article by Murphy and Pazzani[]. >Thus, it seemed like a JAIR comment facility would be a useful >contribution. Peter Turney took this on, and he created a way for >readers to post comments. Unfortunately, almost no comments were >posted. The staff tried seeding a few comments of our own, with >little result. > >It seemed that our readership was reluctant to post comments in a >formal, scientific venue. So Peter tried again. He revised the format, >modeling it after a facility called "NetQ", used by another online >publication. The idea was that readers could send in questions, which >would (optionally) be answered by authors. Then the question and >answer would be posted. This Q/A format proved unpopular as well. > >It is hard to be sure why this never worked. One possibility is that >people are uncomfortable sending inquiries that might be considered >naive to an academic journal. Another possibility is that there are >few burning issues that provoke discussion. Yet another is that >readers prefer to take their comments and questions directly to the >authors, in private correspondence. As for multimedia, JAIR encourages authors to submit "online appendices" containing source code, data, demos, quicktime movies, etc. These are not part of the published article, but they have turned out to be an important contribution of the journal (in my opinion). These appendices can be very valuable. They can turn an article into something that is more than just a written description of the results. They document the original experiments in a way that it is impossible to do with just words. An article describing JAIR's first 5 years can be found at As for reactive e-journals, we've twice created facilities where >readers could comment and ask questions about articles. Neither >attempt was a success. I suspect this is because the journal is an artificial construct. Trying to add discussion to it is getting the tail to wag the dog. The discussion and intellectual to and fro in the academic community is the "dog". The result of the discussion, published papers, is the tail. Almost no journal occupies the whole publication arena for its topic and it is thus fragmentary to seek to tie discussion to articles within an individual journal. I've worked with a list on network policy for some years where members argue strongly on issues. Often drafts of papers or policy submissions are posted for comment yielding discussion. Equally URLs for papers published by members of the group are posted and result in comment - and often argument! The point is that the discussion takes place in an online community. The arbitrary nature of where the material is published in a formal sense is irrelevant. If the publisher has only made the information available in some clumsy format like PDF or Word someone in the community will convert it to HTML to make it easily readable to all. Publication is just a step in an ongoing process and where the publication takes place is incidental to it.

Fr: Mark Dunlop Re: One-day Workshop on Relevance Feedback - Glasgow BCS IRSG Workshop on Relevance Feedback in IR 6 September, 1999 Hosted by the Glasgow IR Group Department of Computing Science University of Glasgow http://www.dcs.gla.ac.uk/rf Relevance feedback (RF) provides techniques to improve a search by utilising relevance information given by a user. This information can be used in a number of ways, e.g. reweighting query terms, adding or deleting query terms, or altering a user profile. As a rule, RF is a successful, practical solution to the uncertainty inherent in information seeking, however the performance of individual techniques can vary over queries, collections and users. RF has also been criticised for not being accessible to users: the basic operation is simple (marking documents relevant) but how users' should make relevance decisions to get the best performance from a RF system is not always obvious. In the current environment of large, diverse collections of multimedia articles, it is important to develop precise, adaptable RF techniques and a more complete understanding of the characteristics of RF. In this workshop we are keen to investigate the diversity of work on RF: from novel algorithms for RF, through theoretical aspects of RF to users' understanding of the techniques. In order to facilitate a discussion-oriented meeting, we are asking for submissions of extended abstracts only. These will be published as a technical report of the meeting. Attendance will be limited, so please register with the organisers. It is not necessary to submit an abstract in order to attend the event. Topics of interest: Papers are solicited dealing with, but not limited to, the following areas: Practical applications of RF Theoretical investigations of RF RF and multimedia Machine learning and RF Semantic RF RF and the user Negative RF RF and user profiling Interactive RF techniques Submission of papers: Deadlines: Authors should submit extended abstracts (approximately 5 sides of A4/US letter) to Ian Ruthven, see below, to arrive no later than July 7th, 1999.

Fr: Zhongfei Zhang Re: ACM SIGIR Workshop on MIIR: CFParticipation Reminder ACM SIGIR'99 Post-Conference Workshop on Multimedia Indexing and Retrieval Berkeley, CA, Call For Participation Background This workshop is a follow-up to last year's very successful workshop on the same topic. Since the field is advancing so rapidly, it was felt that an annual workshop would be worthwhile. The focus is on the required functionality, techniques, and evaluation criteria for multimedia information retrieval systems. Researchers have been investigating content-based retrieval from non-text sources such as images, audio and video. Initially, the focus of these efforts were on content analysis and retrieval techniques tailored to a specific media; more recently, researchers have started to combine attributes from various media. The goal of multimedia IR systems is to handle general queries such as "find outdoor pictures or video of Clinton and Gore discussing environmental issues". Answering such queries requires intelligent exploitation of both text/speech and visual content. Multimedia IR is a very broad area covering both infrastructure issues (e.g. efficient storage criteria, networking, client-server models) and intelligent content analysis and retrieval. Since this is a one-day workshop, we have chosen three focus areas in the intelligent analysis and retrieval area. About the workshop The first focus of this workshop is on integrating information from various media sources in order to handle multimodal queries on large, diverse databases. An example of such a collection would be the WWW. In such cases, a query may be decomposed into a set of media queries, each involving a different indexing scheme. The interaction of various media sources that occur in the same context (e.g., text accompanying pictures, audio accompanying video) is of special interest; such interaction can be exploited in both the content analysis and retrieval phases. The second focus deals with examples of research using content and organization of multimedia information into semantic classes. Users pose and expect a retrieval to provide answers to semantic questions. In practice this is difficult to achieve. Building structures that encode semantic information in a fairly domain independent and robust manner is extremely difficult. A quick review of computer vision research over the last few years points to this difficulty. In many cases, image content can be used in conjunction with user interaction and domain specificity to retrieve semantically meaningful information. However, it is clear that retrieval by similarity of visual attributes when used arbitrarily cannot provide semantically meaningful information. For example, a search for a red flower by color red on a very heterogeneous database cannot be expected to yield meaningful results. On the other hand retrieval of red flowers in a database of flowers can be achieved using color. In context therefore, examples of research using content and organization of multimedia information into semantic classes will be discussed. Many systems, particularly image and video based ones require an example picture which can be used as a query (alternatively, the user may be required to draw a picture). It may be unrealistic to expect an example image to be always available. Thus, it would be useful to find ways of generating new queries. Can NLP techniques be combined with computer vision techniques to generate such queries? Or can multimodal retrieval techniques be combined to create queries suitable for image, video and audio retrieval? In general, a question is how can we create realistic queries for realistic systems. The third focus of this workshop is on evaluation techniques for multimedia retrieval. Currently, most researchers are using the standard evaluation measures defined for text documents; these need to be extended/modified for multimedia documents. There is also a high degree of subjectivity involved that needs to be addressed. Finally, we will also devote one session to discussing MPEG-7 standards and content. By the time of the workshop, the selection committee would have made their choices for standards. We will focus on the following specific topics: - content analysis and retrieval from various media (text, images, video, audio) - interaction of modalities (e.g. text, images) in indexing, retrieval - effective user interfaces (permitting query refinement etc.) - evaluation methodologies for multimedia information. We have found that researchers pay insufficient attention to it. - techniques for relevance ranking - multimodal query formation/decomposition - logic formalisms for multimodal queries - indexing and retrieval from scanned documents - e.g extracting text from images, word spotting - as a retrieval technique for both handwritten and printed documents. - testbeds for evaluating multimodal retrieval: it would be nice to have some resource sharing here since annotating these, and coming up with a good query set are difficult Participation Two types of participation are expected. Those interested in making a presentation at this workshop should submit their full papers either in online postscript version or in hardcopy by regular mail to the address given below. The papers should not exceed 5,000 words, including figures, tables, and references. Those interested in participating, but not presenting papers, should submit a statement of interest, not to exceed 500 words. This should clearly state what aspect(s) of the workshop reflect their research interest. These will be used to select panelists. Both types of submissions are due on Friday, June 18th. Decisions will be made no later than Friday, July 2nd. In the case of paper submission, the final camera-ready papers are due on July 23rd.

Fr: Massimo Melucci Re: SIGIR'99 Workshop: Evaluation of Web Document Retrieval ACM SIGIR '99 Workshop on Evaluation of Web Document Retrieval http://www.dei.unipd.it/~ims/sigir99/ University of California, Berkeley, USA - August 19, 1999 Call for Papers and Participation Deadline postponed to June 18, 1999 Background Since the early days of Information Retrieval evaluation permitted to have insights about IR processes and then to improve retrieval systems effectiveness. Diverse projects, such as TREC and Mira have been addressing for some years different issues of evaluation. Many issues of the Web pose new challenges on evaluating Web document retrieval processes. To name but a few, hypertextual structure, rapid evolution, high heterogeneity, and metadata make evaluation of Web document retrieval rather different from classical evaluation methodologies. The presence of links make browsing-based retrieval a rule than an exception, and then browsing effectiveness should be evaluated as integrated with traditional query-based functions. The rapid evolution of the Web may make retrieval system effectiveness difficult to keep over time. The heterogeneity of Web documents make classical IR techniques poorly effective. Content description-oriented metadata would allow to reduce and control Web document heterogeneity, but their usefulness is still to be evaluated. About the workshop In this workshop we will investigate in depth the evaluation of the use of diverse content descriptive data (e.g. metadata) and search strategies for Web document retrieval. Topics include, but are not limited to, innovative evaluation methodologies concerning: * the use of metadata and other content descriptive data, * browsing and querying Web documents, * the construction of Web document collections, and * search engines and search tools. The workshop will include position paper presentations and discussion, with an emphasis on the discussion. The organizers will select position papers for presentation and arrange the presentations and discussion based on the interests of the attendees. The organizers may invite other presentations as well. Participation Two types of participation are expected: * Those interested in making a presentation at this workshop should submit a position paper of no more than 2,000 words in HTML on the WWW and submit the URL for the paper. * Those interested in participating, but not presenting papers, should submit via e-mail a statement of interest, not to exceed 500 words. This should clearly state what aspect(s) of the workshop reflect their research interest. These will be used to select papers. Both types of submissions are due on Friday, June 18th. Decisions will be made no later than Friday, June 25th. In the case of paper submission, the final camera-ready papers are due in Postscript on Friday, July 9th. Working notes will be made available to all participants at the workshop. All the submissions should be sent both to: Maristella Agosti (agosti@dei.unipd.it) and Massimo Melucci (melo@dei.unipd.it).
