4 semantic technology seminars on May 8th, 9th, 15th, 16th

Mon, 06 May 2019 20:26:27 +0200

Four important seminars are scheduled in this week and the next, held by leading scholars in Natural Language Processing, Data Science, Hybrid Artificial Intelligence, and Deep Learning.
The seminars will be held in Aula Affreschi, Via Zamboni 34, Piano Terra, at 2:30 PM, and are supported by the DHDK master degree and the DHARC (Digital Humanities Advanced Research Center).

Why language technology can’t handle Game of Thrones (yet)

Abstract

Natural language processing (NLP) tools are commonly used in many day-to-day applications such as Siri and Google, but the effectiveness of these technologies is not thoroughly understood. I will present joint work with colleagues from the Vrij Universiteit Amsterdam in which we perform a thorough evaluation of four different name recognition tools on popular 40 novels (including A Game of Thrones). I will highlight why literary texts are so difficult for NLP tools as well as solutions for improving their performance.

Thinking about the Making of Data

Abstract

(This will be an interactive session. Please do me a favor and come prepared with examples of your favorite datasets and recipes of how it was made.)

A central challenge in our modern information environment is how to use, integrate and repurpose data that stem from a multitude of diverse sources. Within data science, ~60-70% of the time is spent gathering, preparing, integrating, and munging data. In science, there is, for instance, the need to know which of the thousands of prior experimental records are reliable, applicable and can be reused for an experiment. In this talk, I discuss the goal of developing intelligent systems that work with people to combine and reuse data. I give examples from my work on flexible knowledge graph construction and contextualize this in the context of recent work looking at how scientist search for data.

Symbolic, Distributed and Distributional Representations in the Era of Deep Learning

Abstract
Natural and Artificial Languages are inherently discrete symbolic representations of human knowledge. Recent advances in machine learning (ML) and in natural language processing (NLP) seem to contradict the above intuition: discrete symbols are fading away, erased by vectors or tensors called distributed and distributional representations. However, there is a strict link between distributed/distributional representations and discrete symbols, being the first an approximation of the second. A clearer understanding of the strict link between distributed/distributional representations and symbols may certainly lead to radically new deep learning networks. In this talk I make a survey that aims to renew the link between symbolic representations and distributed/distributional representations. This is the right time to revitalize the area of interpreting how discrete symbols are represented inside neural networks.

Text Classification and Applications - Seminar by prof. Diego Reforgiato Recupero

Wed, 14 Feb 2018 23:16:56 +0100

Diego Reforgiato Recupero, associate professor at University of Cagliari, will give a seminar on "Text Classification and Applications".

Space-Time:nbsp;Wednesday 21st, 9-10:30am, Via Zamboni 34, piano terra, Laboratorio Grande

Abstract:

Text classification is a core problem in many different domains and to several applications such as document categorization, sentiment analysis, spam detection. The goal of text classification is to assign documents to one or multiple categories. The common approach to solve such a problem is to leverage machine learning and use some of the tools it provides. These tools are classifiers and are based on the concept of learning from examples. In order to build such classifiers we need annotated datasets, which consist of documents previously annotated by humans with their corresponding categories. This technique is also known as supervised because it is based on training sets that supervise the learning process of such classifiers. Concepts such as vectorial space, bag of words, term frequency, tf-idf, n-gram models, performance evaluation, precision-recall analysis and k-cross validation will be covered within the talk. Finally an example of binary classification with WEKA, a suite of free machine learning software including visualization tools and algorithms for data analysis and predictive modeling, will be shown.
