The Linguistic Computing Laboratory (LCL) is part of the Computer Science Department of the Sapienza University of Rome. The group conducts state-of-the-art research in the area of Natural Language Processing.

The group aims at devising and developing algorithms and methods in the context of machine learning, pattern matching and recognition and natural language processing to solve problems related to automatic text understanding, construction, learning and population of ontologies, semantic text indexing and classification, query expansion, question answering, etc.

Research fields include:
  • Word Sense Disambiguation and Induction
  • Ontology Learning and Population
  • Large-Scale Knowledge Acquisition
  • Semantic and Statistical Machine Translation
  • Semantic Information Retrieval
  • Social Network Analysis and Mining
Tutorials in 2014

We are presenting tutorials at four different conferences:
Babelfy released!

We are happy to announce the release of Babelfy which is a unified approach to multilingual Word Sense Disambiguation and Entity Linking.

BabelNet and BabelNet API 2.5 released

As an output of the "MultiJEDI" ERC Starting Grant headed by Prof. Roberto Navigli, we are happy to announce the release of the following two resources:
  • BabelNet 2.5: a very large multilingual encyclopedic dictionary and ontology covering 50 languages, and created by 1) the automatic, seamless integration of WordNet with Wikipedia, OmegaWiki, Open Multilingual WordNet, Wiktionary, and Wikidata and 2) the use of statistical machine translation to acquire a very large amount of multilingual concept lexicalizations.
  • The BabelNet API 2.5: a Java API for programmatic access to BabelNet with just a few lines of code.
BabelNet can also be browsed online with BabelNetXplorer.
ERC Starting Grant!

Prof. Roberto Navigli has been awarded a prestigious ERC starting grant in computer science and informatics (2011-2016). The project, called MultiJEDI, will focus on multilingual semantic processing. Many positions are open on the project.
