COMBO - natural language processing system for more then 40 languages




Paper titeled: "COMBO: State-of-the-Art Morphosyntactic Analysis" has been published in the conference Empirical Methods in Natural Language Processing which held in november 2021. presents COMBO – a fully neural NLP system for accurate part-of-speech tagging, morphological analysis, lemmatisation, and (enhanced) dependency parsing. It predicts categorical morphosyntactic features whilst also exposes their vector representations, extracted from hidden layers. COMBO is an easy to install Python package with automatically downloadable pre-trained models for over 40 languages. It maintains a balance between efficiency and quality. As it is an end-to-end system and its modules are jointly trained, its training is competitively fast. As its models are optimised for accuracy, they often achieve better prediction quality than SOTA.

The COMBO library is available at: https://gitlab.clarin-pl.eu/syntactic-tools/combo. You can find a web demo at: http://combo-demo.nlp.ipipan.waw.pl.

Encryption and compression algorithms for Internet of Things


Prof. Józef Pieprzyk, Dr. hab. Paweł Morawiecki and Dr. Marcin Pawłowski from the Cryptography Team are the authors of the work "Compcrypt - Lightweight ANS-Based Compression and Encryption", published in the journal IEEE Transactions on Information Forensics and Security.

The work was supported by the National Science Center (NCN) as part of the Grant 2018/31 / B / ST6 / 03003 devoted to encryption and compression algorithms. The co-authors of the publication are researchers from Australia (S. Camtepe, A. Mahboubi, S. Nepal) and Dr. Jarosław Duda from the Jagiellonian University

The paper presents a family of compcrypt type algorithms, i.e. lightweight compression-encryption algorithms based on the ANS compression algorithm. The included analysis of the performance and security of compcrypt algorithms has shown their potential usefulness in many application domains, in particular in the Internet of and 5G.

ARTIQ - AI Center of Excellence to suport research and development works in Artificial Intelligence


ARTIQ - AI Center of Excellence - recruitment starts. CD AI will be included in the organizational structures of the Hosting Institutions which, as Beneficiaries of the joint venture, would be responsible for creating appropriate conditions for research teams and their Leaders to achieve the objectives of the projects. One of the Hosting Institutions is the Institute of Computer Science Polish Academy of Sciences (IPI PAN). Please see the dectription about IPI PAN for that competition. The centers will conduct basic research, industrial research, development or pre-implementation works in the field of Artificial Intelligence.

The call for applications will run from September 20 to December 20, 2021 (until 4:00 p.m.).

Our researchers have developed the first comprehensive "Atlas” of regulatory areas active in gliomas


Researchers from the Nencki Institute PAS, the University of Warsaw, and the Institute of Computer Science PAS, have developed the first comprehensive "Atlas” of regulatory areas active in gliomas of various degrees of malignancy, which revealed deregulation of mechanisms controlling gene expression and a new mechanism driving the invasion of malignant brain tumors. The research was published in Nature Communications on June 15, 2021.

The interdisciplinary project Symphony 3 entitled "Atlas of regulatory areas specific for the human brain - a new tool for discovering the pathways causing selected brain diseases" has been carried out by the teams of prof. Bożena Kamińska (Nencki Institute of Experimental Biology of the Polish Academy of Sciences), dr. hab. Bartosz Wilczyński (Faculty of Mathematics, Informatics and Mechanics, University of Warsaw), and dr. Michał J Dąbrowski (Institute of Computer Science of the Polish Academy of Sciences). The project was financed by the National Research Center (NCN).

The most important findings:

  • Revealing the mechanisms regulating gene expression in benign and malignant gliomas.
  • Predicting a new pathway for regulating gene expression related to glioma malignancy, and confirming that this pathway controls cell migration and invasiveness in glioblastoma cells.
  • Creating and sharing an atlas of active regulatory regions in gliomas of various degrees of malignancy and in the brain [http://regulomics.mimuw.edu.pl/].
