** Extended submission deadline: August 8, 2014 **

Taxonomies form the backbone of knowledge-based systems by organizing knowledge in a machine interpretable manner and facilitating information integration. Hierarchical structures provide valuable input in knowledge-intensive applications such as question answering and textual entailment and are useful tools for browsing and navigation of document collections, especially when applied for exploration and discovery.

The TEXAS workshop aims at addressing these issues by providing a venue for presenting and discussing approaches that evaluate taxonomy extraction, and its subtasks (term/concept extraction, term/concept relation discovery, taxonomy construction and cleaning) in the context of semantic applications such as: entity search, entity disambiguation and linking, information integration and summarization, knowledge acquisition, knowledge sharing, inference in NLP tasks (question answering, textual entailment), etc. In this way, progress towards automatically constructed hierarchies can be measured relative to other tasks and real-world applications.

Expected research topics of relevance to the workshop:

application-based evaluation of taxonomies in question answering, document browsing,document clustering, expert finding or other applications;
using automatically constructed taxonomies for searching, browsing and organizing information
constructing taxonomies for/from social media
probabilistic models for topic hierarchies (hierarchical topic modeling)
constructing taxonomies using hierarchical clustering
using distributional models for taxonomy construction
acquisition and modeling of categorical structure and modeling human category acquisition
constructing topic categorization systems and subject hierarchies
constructing hierarchical faceted metadata structures
methods for transforming semi-structured knowledge resources into taxonomies
merging and aligning existing resources for taxonomy construction
comparing, aligning and evaluating existing hierarchical structures
domain glossary acquisition and extracting taxonomies from definitions
constructing application/domain specific taxonomies from existing resources (lexical resources,Linked Open Data, Wikipedia category structure, semantic networks)
using different hierarchical structures (e.g., tree, DAG) and relation types (e.g., hyponymy, meronymy) for taxonomy construction
attaching Named Entities to hierarchical structures and using Named Entities to drive taxonomy construction by extensional analysis
multilinguality and taxonomies: constructing and using multilingual taxonomies

Paper Submissions

Submissions should be made electronically, using Softconf at https://www.softconf.com/emnlp2014/texas2014/.
Submissions should follow the two-column format of ACL 2014 proceedings and should not exceed 8 pages of content and one additional references page.
The LaTeX style files and the Microsoft Word style files tailored for this year's conference are available at: http://emnlp2014.org/call.html.

The reviewing of papers will be double-blind, so please make sure your paper shows the title, but no author information. You should likewise not have any self identifying references anywhere in the paper submitted for review. For example, rather than this: "We showed previously (Smith, 2001), ...", use citations such as: "Smith (2001) previously showed ...". References to your own work in thesis proposals should also be anonymized. You may for example write it as “in X (2000) we showed”, etc. and do not add your papers in the reference list.
