Symposium on Semantics in Systems for Text Processing

http://project.cgm.unive.it/html/STEP2008/index.htm

September 22-24, 2008

Auditorium Santa Margherita

Venice (Italy)

Endorsed by SIGSEM, the ACL special interest group

on computational semantics

MOTIVATION ============

Thanks to both statistical approaches and finite state methods, natural language processing (NLP), particularly in the area of robust, open-domain text processing, has made considerable progress in the last couple of decades. It is probably fair to say that NLP tools have reached satisfactory performance at the level of syntactic processing, be the output structures chunks, phrase structures, or dependency graphs. Therefore, the time seems ripe to extend the state-of-the-art and consider deep semantic processing as a serious task in wide-coverage NLP. This is a step that normally requires syntactic parsing, as well as named entity recognition, anaphora resolution, thematic role labelling and word sense disambiguation, as well as other lower levels of processing for which reasonably good methods have already been developed. Accurate automatic semantic interpretation of text is expected to benefit newly emerging areas targetting semantic and pragmatic issues, such as affectivity and sentiment analysis of texts, textual entailment, and consistency checking.

WORKSHOP SCOPE ================ The goal of the STEP workshop is to provide a forum for anyone active in semantic processing of text to discuss innovative technologies, representation issues, inference techniques, prototype implementations, and real applications. The preferred processing targets are large quantities of texts -- either specialised domains, or open domains such as newswire text, blogs, and wikipedia-like text. Implemented rather than theoretical work is emphasised in STEP. In particular, relevant topics are:

- wide-coverage semantic/logical analysis of text - computation and use of discourse relations - use of lexical-conceptual and semantically related resources - thematic role labelling in semantic representations - word sense disambiguation in semantic representations - implementations of specific semantic phenomena - anaphora or ellipsis resolution in semantic representations - implementations of sentiment analysis - automatic detection of subjective and non-literal language - acquisition of lexical knowledge and paraphrase from raw corpora - background knowledge acquisition, representation, and selection - semantic lexicons and ontologies for text interpretation - learning semantic representations from raw text - automated reasoning in the service of semantic analysis of text - creation of gold standard meaning representations - evaluation of semantic representations - textual entailment and consistency checking - systems that extract, represent or manipulate text meaning - applications of semantic analysis in text processing

Applications inlude, but are not limited to, machine translation, text understanding, question answering, summarisation, information extraction, and the semantic web.

PANEL: COMPARING SEMANTIC REPRESENTATIONS =========================================== STEP 2008 will also feature a panel comparing semantic representations as output by state-of-the-art NLP systems. Participating systems will be given a small number of previously unseen texts. The output will be judged on a number of aspects by a panel of experts in the field. Aim of the panel is to discuss the feasibility of a gold standard for deep semantic representations. The panel will reward the system with the most complete and accurace semantic representation with a special prize. This will be a special event at the workshop.

SUBMISSIONS ============= Authors are invited to submit original research papers. Papers should indicate the state of completion of the reported results. Overlap with previously published work should be clearly indicated. Submissions will be judged on correctness, novelty, technical strength, clarity of presentation, significance, and relevance to the workshop.

Submissions should be in Abobe PDF format, not exceed eight A4-sized pages, and be typeset in a 12 point font. Detailed guidelines and a latex stylefile will be available at the STEP 2008 web page. Each submission will be reviewed by at least two members of the programme committee. Accepted papers will be published in the workshop proceedings. The publication of selected and revised papers is under consideration for a special issue in a journal.
