SyntagNet, a resource with 88,000 lexical-semantic combinations, is now out!

We are proud to announce that SyntagNet 1.0 ( is now available for download at Developed at the Sapienza NLP group (, the multilingual Natural Language Processing group at the Sapienza University of Rome, SyntagNet is a manually-curated large-scale lexical-semantic combination database which associates pairs of concepts with pairs of co-occurring words. The goal of SyntagNet is to capture sense distinctions evoked by syntagmatic relations (e.g. mouse.n.1 and squeak.v.1 vs mouse.n.2 and click.n.4), hence providing information which complements the essentially paradigmatic knowledge shared by currently available Lexical Knowledge Bases such as WordNet. Its main features are:

  • Wide coverage, with 78,000 noun-verb and noun-noun lexical combinations extracted from the English Wikipedia and the British National Corpus.
  • High-quality, fully manual disambiguation for all of the lexical combinations, according to the WordNet 3.0 sense inventory.
  • A resulting Lexical Knowledge Base made up of 88,019 semantic combinations linking 20,626 WordNet 3.0 unique synsets with a relation edge.
  • A user-friendly web interface for looking up terms and their lexical-semantic combinations, with complete linkage to BabelNet 4.0.

And much more! Please check out our EMNLP 2019 paper:

or for more details!

SyntagRank, a state-of-the-art knowledge-based Word Sense Disambiguation system which uses SyntagNet to perform disambiguation in five languages (English, French, German, Italian and Spanish) is also available from the same website (will be demoed at ACL 2020!).

SyntagNet is an output of the MOUSSE ERC Consolidator Grant No. 726487 and of the ELEXIS project No. 731015 under the European Union’s Horizon 2020 research and innovation programme. Babelscape proudly developed the online interface and API, and provides the infrastructure for maintaining the service.

The Conference on #NLP KONVES new deadline



The Conference on Natural Language Processing (“Konferenz zur Verarbeitung natürlicher Sprache”, KONVENS) aims at offering a broad perspective on current research and developments within the interdisciplinary field of natural language processing. It allows researchers from all disciplines relevant to this field of research to present their work. The conference will take place September 19–21, 2016 in Bochum (Germany). We are pleased to announce that John Nerbonne and Barbara Plank will give invited talks at the conference.

Call for Papers

We welcome original, unpublished contributions on research, development, applications and evaluation, covering all areas of natural language processing, ranging from basic questions to practical implementations of natural language resources, components and systems.

The special theme of the 13th KONVENS is: “Processing non-standard data — commonalities and differences”.

A wide range of data can be considered “non-standard” because it deviates in one way or the other from standard written data such as newspaper texts. Examples include:
* data produced by language learners
* historical data
* data from social media
* (transcriptions of) spoken data

We especially encourage the submission of contributions comparing different types of non-standard data and their properties, focussing on their impact for natural language processing. For example, a feature common to many types of non-standard data is the use of non-standard spelling. However, spelling variation in learner data as compared to historical data is due to very different reasons and, most likely, resulting in very different types of non-standard spellings.

Topics that we would like to see addressed include:
* Common properties of (many) non-standard data, e.g. non-standard spelling, data sparseness, features of orality
* Impact of the commonalities and differences of non-standard data on the methods and tools that are applied to the data, e.g. normalization vs. tool adaptation, evaluation without gold standard, etc.

Important Dates
NEW: June 7, 2016  Paper submissions due
NEW: July 18, 2016 Notification of acceptance
August 15, 2016    Camera-ready copy due
September 19–21, 2016  Conference


We welcome two types of contributions:
* Full papers for oral presentation (8 pages plus references)
* Short papers for presentation as posters (4 pages plus references)

Short papers/posters can be combined with a system demonstration. Reviews will be anonymous. Accepted full and short papers will be published in the conference proceedings.

Submissions must conform to the formatting guidelines, and must be made electronically through the conference website (see

The conference languages are English and German. We encourage the submission of contributions in English.

Evaluating complexity in syntax

Presentation by Phillippe Blache, Laboratoire Parole et Langage, CNRS & Aix-Marseille Université

Part of the Measuring ling. complexity: A multidisciplinary perspective workshop at UCL, Belgium, 24 April 2015

Complexity means different things to different people

System vs Structural complexity (Dahl, 2004)

Existing models: incomplete dependency hypothesis, dependency locality theory, early intermediate constituents principle, activation. However, they all fail to describe language in natural environment.

Challenges: dealing with natural data and dealing with language in its context, esp. spoken language and natural interaction.

Hypothesis: difficulty depends on the search space size. The larger the search space, the more difficulty.

The more properties, the smaller the search space. Maximize online principle  (Hawkins, 2004).

Generative grammar is a very restrictive view.

Property grammars: linguistic statements as constraints (filtering + instantiating)

Basics: constraints are independent, linear precedence.

Constraint violation is possible.
