Second Call for Papers

International Workshop on
''Crossing media for improved information access''
Tuesday, 23 May 2006
Half-day workshop (morning session)
www.reveal-this.org/Workshops-Events/lrec06

In Association with the 5th International Conference on Language Resources and Evaluation, LREC 2006
http://www.lrec-conf.org/lrec2006/
Main Conference: 24-25-26 May 2006
Magazzini del Cotone Conference Centre
Genoa, Italy

The i2010 initiative, adopted under the renewed Lisbon agenda, concerns
information, communication and media industries and caters, among others, for the possibility of European citizens to ''watch or listen to audiovisual content anytime, anywhere and on all technical platforms (TVset, computer, mobile phone, personal digital assistant, etc.)''. In fact, much of the information that reaches the user nowadays is in digital form: digital radio, music CDs, MP3 files, digital satellite and digital terrestrial TV, personal digital pictures and videos and, last but not least, digital information accessed through the Web. This information is heterogeneous, multimedia and, increasingly, multi-lingual in nature.

The development of methods and tools for content-based organization and filtering of this large amount of multimedia information that reaches the user is a key issue for effective content consumption. Advances in medium-specific (audio, image, text) processing have facilitated the development of tools for indexing multimedia content. It is no coincidence, for example, that text-based indexing methods of such content prevail; text processing has reached a level of maturity that enables shallow semantic analysis for identifying keywords, terms and named entities as indexing terms, with considerable progress being made in the extraction of events and facts, i.e. a wealth of information for more accurate indexing. Experiments are ongoing on applying this type of indexing on speech recognition output as such or/and on associating web text to such output (for recovering from ASR mistakes) and then performing text-based indexing (cf. work within the PRESTOSPACE project, www.prestospace.org); speech processing can provide automatic speech transcriptions of good quality (in certain acoustic conditions), as well as speaker turn and identification information. On the other hand, image-based indexing methods for multimedia content rely on basic image processing and in particular on the extraction of keyframes, shotcuts and low-level image features, while progress in developing face detection, face identification and object recognition technologies contribute to a more promising future for such approaches.

However, competitions such as TRECVID and Image-CLEF have shown that some benefits in performance can be gained through the fusion of the results of visual and linguistic analyses of multimedia content. Research on the automatic association of images with corresponding textual data go beyond fusion of medium-specific results to multimedia integration for, among others, indexing and retrieval applications (cf. work on UP-TV, ACEMEDIA and BUSMAN projects), while a more general notion of ''crossing media'' within or/and across documents seems to emerge too (cf. the REVEAL THIS project, www.reveal-this.org).

The workshop aims at exploring these new tendencies in accessing multimedia content by bringing together researchers working on the development of indexing technologies for archived and contemporary multimedia content. The focus of the workshop is the notion of ''cross-media'' mechanisms for multimedia indexing and retrieval and its realisation in research prototypes. Topics of interest to the workshop include (but are not limited to):

- Exploration of the notion of ''cross-media'' mechanisms

- Modality/medium interaction relations in multimedia data collections

- Methods for cross-media indexing within and/or across documents

- Medium-specific processing for facilitating cross-media indexing

- Resources needed/built for cross-media indexing

- Annotation needs for cross-media indexing resources

- Evaluation methods

Message 2: Diachronic Typology of Voice and Valency-Changing Categories

Linguistic Field(s): Historical Linguistics; Morphology; Syntax; Typology

Call Deadline: 20-Mar-2006

Meeting Description:

The workshop will bring together scholars working on voice and valency phenomena in both languages (language families) with well-documented history and languages which furnish less historical evidence but, nevertheless, can furnish valuable data on the basis of comparison of daughter languages and linguistic reconstruction. Contributions based on our 'Questionnaire for a diachronic typological study of valency-changing categories' are particularly welcome.

The last decades of the 20th century are marked with the rapid development of the typological study of voice and other valency-changing categories, such as passive, causative, reflexive, antipassive and anticausative (decausative). We now dispose of rich catalogues of possible systems of valency-changing derivations attested in the languages of the world. More specifically, we know a lot about the morphological, syntactic and semantic synchronic properties of these categories. On the other hand, a systematic treatment of these categories in a diachronic perspective is lacking. The rise, development and decline of these categories mostly remain on the periphery of the typological interests. Such an imbalance of the synchronic and diachronic typology (which is not limited to the valency-changing categories) has a number of reasons.

One of the main reasons for this imbalance can be found in the fact that synchronic linguistics have at its disposal the material of hundreds of languages of various genetic affiliation and different structural types, whereas the material for diachronic typological generalizations is much more limited. There are relatively few languages for which we dispose of textual evidence for the period sufficient to observe essential changes in the morphological system and syntactic types (say, 1000 years or more). A good many of these languages belong to two major families, Indo-European and Afro-Asiatic. This unavoidably limits the typological diversity of the data.

This being the state of affairs, it is advisable to start a diachronic typological research with collecting evidence from languages (language groups) with a history well-documented in texts for a sufficiently long time span (no less than 1000 years). On the other hand, in the case of languages with lesser documented history, important generalizations can be obtained on the basis of comparison of genetically related languages, which can serve as a basis for reconstruction of possible scenarios of changes within the system of valency-changing categories. Approaching the history of a particular valency-changing category, such as passive or causative, it might be useful to trace the relevant category C (passive, causative etc.) from the earliest attested texts in an ancient language (L0) onwards up to its reflexes in the daughter languages (L1, L2 etc.). Of particular interest would also be - if available - evidence from the sister languages of L0 (L, L etc.), which can serve as a basis for a tentative reconstruction of the hypothetical history and possible sources of C in proto-language *L.

These and related issues will be in the spotlight of the workshop ''Diachronic typology of voice and valency-changing categories''. The idea of our workshop is to bring together scholars working on valency phenomena in both (1) languages (language families) with well-documented history (such as Indo-European or Semitic) and (2) languages which furnish less historical evidence but, nevertheless, can provide us with some valuable data on the basis of comparison of daughter languages and linguistic reconstruction (as is the case with Uralic). Ideally, a typologically-oriented study of a valency-changing category in a diachronic perspective should be organized in accordance with a questionnaire, such as those widely used in synchronic typology, for instance, in the framework of the Leningrad / St. Petersburg Typological School (cf. the questionnaire for a study of resultatives outlined in Typology of resultative constructions, ed. by Vladimir Nedjalkov, Amsterdam, 1988, p. 57ff.). We believe that using a questionnaire will render our workshop more effective and, eventually, make the collection of papers more publishable. Accordingly, the selection of papers will slightly differ from the usual procedure. If you are interested in the general topic of the workshop, please take a look at our ''Preliminary questionnaire for a diachronic typological study of valency-changing categories'' (available at http://www.hum.utu.fi/ylkielitiede/questionnaire.pdf).

We strongly encourage you to submit a paper along the guidelines outlined in this questionnaire - which, as we hope, will contribute to the maximal mutual intelligibility between the participants and to the efficiency of the workshop. Papers providing explicit answers to at least some questions of this questionnaire in an individual language or group of languages and discussing various aspects of the diachronic typology of valency-changing categories will be particularly welcome. Please send us a detailed abstract (up to 2 pages) of your paper no later than March 20th. We will give priority to papers that follow the guidelines suggested in the questionnaire, but other papers may also be considered, as long as they deal with the development of valency categories in and/or across languages. The organizers reserve, if necessary, the right to approach the author(s) of proposed papers, in order to encourage him/her/them to modify the topic of the paper, focusing on some particular aspects of the problem in question. We hope that this will help to organize our workshop, making it more homogenous and, eventually, more efficient.

The workshop will be arranged as a part of the symposium 'Structure and Context' organized by The Linguistic Association of Finland (SKY) to be held August 21-22, 2006 in Turku (Åbo Akademi University), Finland.

Please visit http://www.ling.helsinki.fi/sky/tapahtumat/context/context.shtml for the SKY Symposium (these pages will include practical information: how to get to Turku, the venue of the symposium, accommodation, etc.).

Please do not hesitate to approach us in the case you have any questions about the workshop, in particular, the range of topics you would like to deal with.
