In social media, attention concentrates on a relatively small number of popular items, while the vast majority of content produced by the crowd is almost neglected. Although popularity can be an indication of the perceived value of an item within its community, previous research has hinted to the fact that popularity is distinct from intrinsic quality. We embarked in a journey to quantitatively measure intangible properties such as quality and beauty using a multidisciplinary approach that ranges from social sciences to deep learning. Our research shows how algorithms that can reliable capture quality can democratise social media, improve our experience of online web services and even help us living a better life in our cities.
Question answering (QA) systems are able to answer questions posed by humans in a natural language. QA is a discipline within the fields of Information Retrieval (IR) and Natural Language Processing (NLP) that involves several machine learning approaches that need to scale on a huge amount of textual data.
QA is a complex task that requires to deeply understand the question, search relevant documents and extract the correct answer from the retrieved documents. This talk provides a brief introduction to QA focusing on the NLP and machine learning techniques, followed by details about a QA framework called QuestionCube.
Finally, I will present two different scenarios where QA is successfully applied: a famous language game called “Who Wants to Be a Millionaire?” and a semantic search engine for FAQs developed for supporting customers in a real application.
Algorithms and decision making based on Big Data have become pervasive in all aspects of our daily (offline and online) lives. Social media, e-commerce, professional, political, educational, and dating sites, to mention just a few, shape our possibilities as individuals, consumers, employees, voters, students, and lovers. In this process, vast amounts of personal data are collected and used to train machine-learning based systems. These systems are used to classify and rank people, and can discriminate us on grounds such as gender, age, or ethnicity, even without intention, and even if legally protected attributes, such as race, are not explicit in the data. Algorithmic bias exists even when there is no discrimination intention in the developer of the algorithm. Sometimes it may be inherent to the data sources used (software making decisions based on data can reflect, or even amplify, the results of historical discrimination), but even when the sensitive attributes have been suppressed from the input, a well trained machine learning algorithm may still discriminate on the basis of such sensitive attributes because of correlations existing in the data.
From a technical point of view, efforts at fighting algorithmic bias have led to developing two groups of solutions: (1) techniques for discrimination discovery from data and (2) discrimination prevention by means of fairness-aware data mining, develop data mining systems which are discrimination-conscious by-design. In this talk we mainly focus on the first groups of solutions. This talk is joint work with Sara Hajian and Francesco Bonchi, and an extended version of it was presented as a KDD 2016 tutorial: http://francescobonchi.com/algorithmic_bias_tutorial.html

Even if the term Big Data, is not always used with the same meaning, man agrees to say that it brings many challenges. When regarding the whole process related to the big-data context, starting from the generation of data, its storage and management, and analyzes that can be driven in order to help decision making, at each phase some important challenges arise. Indeed, during the generation and capture of data, some challenges may be related to technological aspects linked to the acquisition of real-time data, for example. But at this phase, challenges are also related to the identification of meaningful data. The storage and management phase leads to two critical challenges, first on the infrastructures for the storage of data and its transportation, but also on conceptual models to provide well-formed available data that may be used for analysis purpose. Then, the analysis phase has its own challenges, with the manipulation of heterogeneous massive data. In particular, when considering the knowledge extraction, in which unknown patterns have to be discovered, analysis may be very complex due to the nature of data manipulated. This is the heart of the data mining. A way to address data mining problems is to model them as optimization problems that can be of multi-objective nature. In the context of Big Data, most of these problems are large scale ones. Hence meta-heuristics seem to be good candidates to tackle them. But, it should be noticed that meta-heuristics are not only suitable to address the large size aspect of the problem but also to deal with other aspects of Big Data, such as variety and velocity for example. The aim of this special session is to group contributions in which meta-heuristics and multi-objective optimization can provide answers to some of the challenges induced by the Big Data context, and in particular within the data analytics phase. The scope of the special session MMO-BD includes, but is not limited to the following topics:
– Meta-heuristics for supervised data mining tasks (classification, association rules…)
– Meta-heuristics for unsupervised data mining tasks (clustering, bi-clustering…)
– Meta-heuristics for mining heterogeneous data
– Meta-heuristics for text mining
– Multi-objective models for data mining tasks

“Mathematical Analysis of Nature-Inspired Algorithms”
School of Science and Technology
Middlesex University London
Many problems in optimization and computational intelligence are very challenging to solve, and some of these problems can be NP-hard, which means that there are often no efficient algorithms to tackle such hard problems. In many cases, nature-inspired metaheuristic algorithms can be a good alternative and such algorithms include genetic algorithms (GA), particle swarm optimization (PSO), ant colony optimization (ACO) and many others. Over the last two decades, nature-inspired optimization algorithms have become increasingly popular in solving large-scale, nonlinear, global optimization with many real-world applications. They also become an important of part of optimization and computational intelligence. This tutorial will provide a critical analysis of recent algorithms using mathematical theories such as Markov chains, dynamic systems, random walks and self-organization systems. This will provide some insight into these algorithms concerning their convergence rates and stability.
Audience and expected participants:
All participants, especially young researchers, who wish to gain in-depth understanding of evolutionary algorithms or to carry out more research in theoretical aspects of algorithms.
Timeliness of the Tutorial:
The number of new nature-inspired algorithms, especially those based on swarm intelligence or inspiration from natural systems, has increased significantly in recent years. It is estimated that there are more than 100 different variants of nature-inspired algorithms. Therefore, this tutorial is a timely attempt to provide a critical analysis of recent algorithms from a mathematical perspective and analyse these algorithms using a unified mathematical framework.
Topics and Format:
This tutorial intends to introduce the fundamentals and latest advances of the state-of-the-art nature-inspired algorithms with the focus on mathematical analysis on new algorithms using a unified theoretical framework of Markov chain theory, random walks, dynamic systems and self-organization theory. Topics include

The MOD 2017 Organizing Committee invites proposals for Special Sessions and Tutorials.
Special session proposals are invited to the 3rd International Conference on Machine learning, Optimization and big Data (MOD) to be held in Volterra (Pisa) Tuscany, Italy on September 14-17, 2017.
A special session proposal should include the title, aim and scope of the proposed session, list of potential contributors, and the names, e-mail addresses, affiliations and short bios of the organizers.
Special session proposals will be evaluated based on the timeliness of the topic, its uniqueness, and qualifications of the proposers. The proposers are expected to have a PhD degree and have a good publication track record in the proposed area. A tentative accept/reject decision on the proposal will be sent to the proposers within a few weeks after its receipt by the Special Sessions Chair. Accepted special sessions will be listed on the website. However, it is likely that an accepted proposal will be combined with similar proposals to avoid multiple special sessions covering a similar topic. A final decision will be made two weeks after the special session proposal deadline (
April 15, 2017).
Submissions of papers to special sessions should be done through the paper submission website of MOD 2017 where authors can choose a special session title as the main topic of their paper from a list of regular session topics and special session titles. All papers submitted to special sessions will be subject to the same peer-review review procedure as the regular papers. Special sessions having fewer than accepted papers will be cancelled and the accepted papers will be moved to regular sessions.
Special Session Proposals should be sent by email to: firstname.lastname@example.org
All Special Session Proposals should be submitted by
