Data Science Seminars

Why analyze biomedical text if we have data?

Transmissão através de Videoconferência

Speaker: Francisco Couto (LASIGE/DI-FCUL).

Abstract: Our daily quest for knowledge usually starts in a search engine with a text query, not a SQL query. Text is still the main tool that we humans use to communicate and publish our findings and the context in where they were generated. Biomedical data repositories lack the flexibility to fully represent most of our hypotheses, theories, deductions, proofs, assumptions, observations and experimental evaluations that support the stored scientific facts. Moreover, absolute truth is not part of science, so biomedical text is crucial for enabling proper scientific inquiry and interpretation of facts for a particular context. However, text analysis is a tedious and time-consuming task for humans and a hard and prone to error task for machines. This talk will give a brief introduction to how text mining coupled with ontologies can address this challenge, using technologies that range from regular expressions to recent deep learning algorithms, and from natural language processing techniques to semantic similarity. The talk will end with an overview of the most recent contributions made by LASIGE researchers in this topic, namely in named-entity recognition and linking, relation extraction, question and answering, recommender systems, and multilingual international evaluations.

Bio: Francisco M. Couto is currently an associate professor with habilitation at Universidade de Lisboa (Faculty of Sciences) and a researcher at LASIGE. His main research contributions cover several key aspects of bioinformatics and knowledge management, namely in proposing and developing various text mining solutions that explore the semantics encoded in ontologies. Until November 2020, he published 2 books; was co-author of 8 chapters, 52 journal papers (41 Q1 Scimago), and 32 conference papers (10 core A and A*); and was the supervisor of 8 PhD theses and of 45 master theses. He received the Young Engineer Innovation Prize 2004 from the Portuguese Engineers Guild, and an honorable mention in 2017 and the prize in 2018 of the ULisboa/Caixa Geral de Depósitos (CGD) Scientific Prizes.

Um curso dirigido ao público em geral e a estudantes de arte ou ciência (a partir dos 16 anos), com interesse em desenho de observação, ilustração e biologia, com ou sem experiência em desenho.

The objective of this course is to introduce participants to the details of communication and writing scientific publications.

Um programa de aceleração de ideias e negócios, promovido pela redeSaúde, com candidaturas até 30 de setembro de 2021.

The objective of this course is to introduce participants to the details of communicating science to non-specialized audiences, including, but not exclusive to, public and private stakeholders, students and teachers, and media professionals.

This course aims to evidence the importance of natural history collections for the study of biodiversity, to show new tools and approaches to extract and disseminate biodiversity data from natural history collections and to increase awareness of young researchers for the scientific and cultural value of Natural History Museums.

The course aims at providing an introduction to stable isotopes ratios as tools to understand global, ecosystem and community level bio/geo cycles; light isotopes: H, N, C, O and S isotopes, geo cycles and ecological significance; sampling and analytical methodologies in stable isotope analysis.

EvoS aims at turning evolutionary theory into a common language to areas that pertain to the natural world, including human affairs.

The course SoilEco aims at introducing attendants to an updated state of the art of diversity of the soil biota and the functional roles played by soil organisms in key ecological processes.

In this course, we promote a multidisciplinary approach presenting the most recent findings on the topic and challenging the traditional way of considering symbiotic associations as exceptions and not as the rule.

The goal of this course is to provide to the participants with current and practical knowledge on urban ecology, including ecological and social aspects.

This course aims to explore ways of communicating science to non-specialized audiences, such as policy makers, industry, general public (including students and teachers), through their engagement and participation in citizen science activities.

This course introduces the field of island biogeography, a discipline that has long influenced other research areas such as macroecology, community ecology, evolution and conservation biology.

Scientists, as the main actors in the production of scientific knowledge, have the responsibility of having an active voice in communicating this knowledge – and that can be achieved for example by a conscious use of the communication tools at their disposal and a better articulation with journalists, among other means.
