Challenges for Wordnets

A workshop co-located with LDK 2017:
The first conference on Language, Data and Knowledge

18 June, Galway, Ireland

Submit now


Wordnets are increasingly widely used to model word meaning in natural language processing tasks. However, there are still many challenges in accurately describing word meanings and making these descriptions useful for both human and machine users. This workshop aims to identify, discuss and start to solve existing challenges.


Much research on wordnets focuses either on their construction or their use in some application. Few papers bridge the gap by discussing how different wordnet models and construction methods affect their effectiveness in use, or how different applications require different parts of language to be modeled.

For this reason, we are experimenting with a new workshop series challenges for wordnet, to give wordnet users and developers a chance to share experiences both good and bad. It will be co-located with the First Conference on Language, Data and Knowledge (LDK 2017) in Galway, Ireland. The workshop will start with some short presentations and then finish with an extended discussion based on the challenges presented. We welcome position statements on the following (or related) topics:

  • Issues for Modeling Languages
    – missing parts-of-speech in wordnet (e.g. prepositions, conjunctions)
    – incomplete representation (e.g. semantics of adverbs)
    – links to examples/corpora
    – what is a wordnet
    – basic building blocks of a wordnet
    – language/dialect differences
  • Issues of Compatibility
    – integration with other resources
    – wordnets vs ontologies
    – licenses
  • Application Issues
    – consistent coverage
    – named entities
    – scaling up
    – wordnet services: WSD, similarity…
    – maintenance
    – versionings and updating
  • Evaluation
    – quality measures
    – experts vs crowds
    – translation vs monolingual construction


Please submit papers of between 4-10 pages, excluding references, formatted using the Springer Lecture Notes in Artificial Intelligence formatting guidelines. Submissions should be anonymous. Submissions will be reviewed by at least 3 reviewers and will be made available on online prior to the workshop.

Authors of good submisions will be invited to submit extended versions for a special issue of the Cognitive Studies | Études cognitives journal ( The extended versions will be carefully peer reviewed, but the scope of this special issue will be set in advance.

Papers should be submitted via EasyChair

The workshop is supported by the CLARIN-PL research infrastructure (

We have made available a vector word model learned with neural networks

The published model describes words of natural language by means of multidimensional vectors. The vectors refer to words’ hidden properties which are motivated by the layers of the neural network. The model may be used for determining the degree of word similarity to which specific vectors relate and thus for the generation of word frequency lists.

The model is available at our repository on the D-Space platform:

SummaryThe goal of the workshop is to improve the interoperability, usability and ease of access of CLARIN lexico-semantic resources in order to build a CLARIN open virtual lexical platform facilitating better access to lexical resources by Humanities & Social Sciences (H&SS) users and research web applications.
The topics will include:
the choice of a few common formats for CLARIN lexico-semantic resources (LSR);
the design of a system of web services for accessing CLARIN LSRs,
the common virtual platform for linking, displaying and browsing LSRs;
gathering requirements from H&SS related to LRSs and the platform.
The outcome will be an integrated report with an action plan that will be offered to the wider CLARIN community for further discussion, testing and refinement. The workshop is planned for 3 invited experts and up to 25 participants in total.

Full Description
Workshop goal
The main goal of the workshop is to initiate the works on the improvement of interoperability, usability and ease of access of CLARIN LRSs for the needs of a their better visibility for H&SS users and their enhanced utilization in research applications. The key idea is to coordinate development of a system of web services for accessing LRSs and a common virtual lexical platform built on the top of them. The platform is intended to be an open generic solution that will allow for effective linking, displaying and browsing of the rich variety of data included in CLARIN LRSs. One of the functions of the platform will be a kind of federated search for LRSs. The platform will be an open solution with potentially many installations and many web application based on them.

The main topics will include:

1. the choice of a few common formats for CLARIN lexico-semantic resources (LSR);
2. the design of a system of web services for accessing CLARIN LSRs,
3. the common virtual platform for linking, displaying and browsing LSRs;
4. gathering requirements from H&SS related to LRSs and the platform.

The outcome of the workshop will be an integrated report with an action plan for each of the key topics discussed in the working groups. It will be next offered to the wider CLARIN community for further discussion, testing and refinement. The first, limited set of standards and requirements will be selected for further work. As a follow up we will also prepare a joint proposal of CLARIN type II workshop devoted to the construction of a first set of web services for accessing selected LRSs and a first prototype of the platform. The platform development is planned to be a collaborative work, but CLARIN-PL is prepared for serve as the main developer due to a similar goal in its action plan.

Link to CLARIN strategic priorities
The topics of the workshop are closely related to several CLARIN strategic pillars (cf. CE-2015-0657), namely:
integration of data – the common format and strategy of integration will form the basis for the interoperable multifaceted resources and will thus enable “the development of tools that allow for mapping between different standards”
integration of services – the common platform and system of web services will simplify providing multilingual web services for semantic annotation, exploration, exploitation, enhancement, analysis, manipulation and visualization of language data; support for mono- and multilingual processing workflows,
ease of access – the common platform and system of web services will simplify access to different types of lexico-semantic resources. They will will enhance multilingual browsing and visualization services.
crossing borders – the common format, platform and strategy of integration will facilitate crossing borders between languages, countries, and infrastructures; “international collaboration both at the RI and at the thematic level”.
