The Sapienza Natural Language Processing Group (Sapienza NLP) is part of the Computer Science Department of the Sapienza University of Rome.

Our group aims at devising and developing innovative approaches to multilingual Natural Language Understanding. We pursue a vision focused on integrating explicit, symbolic knowledge with deep learning.

The group's work is financed by several sources of funding, including ERC grants, other EU and national projects, and the Babelscape Sapienza spin-off.

The Sapienza NLP group is proud to present 2 papers at COLING 2020: "Bridging the Gap in Multilingual Semantic Role Labeling: a Language-Agnostic Approach" and "Conception: Multilingually-Enhanced, Human-Readable Concept Vector Representations".

SapienzaNLP @ EMNLP 2020

We are proud to announce that SapienzaNLP has 4 + 1 papers accepted at EMNLP 2020: 4 long papers at the main conference and 1 demo paper. Our contributions touch several areas from Word Sense Disambiguation to Semantic Parsing and Semantic Role Labeling.

SapienzaNLP @ ACL 2020

We are proud to announce that SapienzaNLP has 4 papers accepted at ACL: 2 long, 1 short, and a demo, making up almost half of the accepted papers from Italian institutions (4 out of 9). Our works lie in the areas of lexical semantics, multimodal representation learning and multilinguality.

VerbAtlas is now out!

We are proud to announce that VerbAtlas 1.0 ( is finally available for download.
Developed at the Sapienza NLP group, the multilingual Natural Language Processing group at the Sapienza University of Rome, VerbAtlas is a novel large-scale manually-crafted semantic resource for wide-coverage, intelligible and scalable Semantic Role Labeling. The goal of VerbAtlas is to manually cluster WordNet synsets that share similar semantics into a set of semantically-coherent frames.
