Conceptual input of a dictionary user. What is in the authors' minds when they are generating a message and looking for a word? Do they start from partial definitions, i.e. underspecified input (bag of words), conceptual primitives, semantically related words, something akin to synsets, or something completely different? What does it take to bridge the gap between this input, incomplete as it may be, and the desired output (target word)?
Organizing the lexicon and indexing words. Concepts, words and multi-word expressions can be organized and indexed in many ways, depending on the task and language type. For example, in Indo-European languages words are traditionally organized in alphabetical order, whereas in Chinese they are organized by semantic radicals and stroke counts. The way words and multi-word expressions are stored and organized affects indexing and access. Since knowledge states (i.e. knowledge available when initiating search) vary greatly and in unpredictable ways, indexing must allow for multiple ways of navigation and access. Hence the question: what organizational principles allow the greatest flexibility for access?
Access, navigation and search strategies based on various entry types (modalities) and knowledge states. Words are composed of meanings, forms and sounds. Hence, access should be possible via any of these components: via meanings (bag of words), via forms, simple or compound ('hot, dog' vs. 'hot-dog'), and via sounds (syllables). Access should even be possible, if input is given in an incomplete, imprecise or degraded form. Furthermore, to allow for natural and efficient access, we need to take the users' knowledge into account (search space reduction) and provide adequate navigational tools, metaphorically speaking, a map and a compass. How do existing tools address these needs, and what could be done to go further?
NLP applications: Contributors can also demonstrate how such enhanced dictionaries, once embedded in existing NLP applications, can boost performance and help solve lexical and textual-entailment problems, such as those evaluated in SEMEVAL 2007, or, more generally, generation problems encountered in the context of summarization, question-answering, interactive paraphrasing or translation.
- Deadline for paper submissions: May 30, 2010
- Notification of acceptance: June 30, 2010
- Camera-ready papers due: July 10, 2010
- Cogalex workshop: August 22, 2010
The 7th International Conference on Cognitive Science (ICCS) which takes place August 17 to 20, 2010, just before COLING. It is our hope that this unique opportunity will foster scientific exchange between the scientific communities of Computational Linguistics and Cognitive Science. The ICCS' venue is the China National Convention Center (CNCC) which is close to COLING's site, the Beijing International Convention Center (BICC), located on the other side of the China National Stadium ('Bird Nest').
Also somewhat related is the 6th IEEE International Conference on Natural Language Processing and Knowledge Engineering (IEEE NLP-KE'10). Yet, as it is scheduled for August 21 to 23, 2010, it overlaps with our workshop.
