Special Issue of Cybernetics and Information Technologies Journal
Semantic Models for NLP


Deadline Extension

The new deadline is: 1 July 2017


With the availability of large language data online, cross-linked lexical resources (such as BabelNet, Predicate Matrix and UBY) and semantically annotated corpora (SemCor, OntoNotes, etc.) more and more applications in NLP have started to exploit various semantic models. The semantic models have been created on the base of LSA, clustering, word embeddings, deep learning, neural networks, etc. and abstract logical forms, such as Minimal Recursion Semantics (MRS) or Abstract Meaning Representation (AMR) etc.

Additionally, the Linguistic Linked Open Data Cloud has been initiated (LLOD cloud) which interlinks linguistic data for improving the tasks of NLP. This cloud has been expanding enormously for the last four-five years. It includes corpora, lexicons, thesauri, knowledge bases of various kinds, organized around appropriate ontologies, such as LEMON. The semantic models behind the data organization as well as the representation of the semantic resources themselves are a challenge to the NLP community.

The NLP applications that extensively rely on the above discussed models include Machine Translation, Information Extraction, Question Answering, Text Simplification, etc.

The idea behind this Special Issue is to gather contributions on the creation, maintenance and usage of semantic models for specific NLP tasks. We are interested in both – supervised and unsupervised approaches as well as in models that are predefined in structured resources or extracted on-the-fly from unstructured data.

Topics of Interest Include but are not Limited to:
