Large collections of symbolic music documents need efficient information retrieval tools. We introduce FACETS, a versatile tool for exploring and management of such collections. FACETS is a scalable and flexible content-based search engine, offering melodic and rhythmic querying modes. For improved navigation, a faceted interface orders the results, to reduce information overloading, and it may be used as a primary entry point in the tool. FACETS is available as a standalone Docker image and Github repository, aiming to help musicologists, composers, MIR researchers and the interested public.

We address the problem of scalable content-based search in large collections of music documents. Music content is highly complex and versatile and presents multiple facets that can be considered independently or in combination. Moreover, music documents can be digitally encoded in many ways. We propose a general framework for building a scalable search engine, based on (i) a music description language that represents music content independently from a specific encoding, (ii) an extendible list of feature-extraction functions, and (iii) indexing, searching, and ranking procedures designed to be integrated into the standard architecture of a text-oriented search engine. As a proof of concept, we also detail an actual implementation of the framework for searching in large collections of XML-encoded music scores, based on the popular ElasticSearch system. It is released as open-source in GitHub, and available as a ready-to-use Docker image for communities that manage large collections of digitized music documents.

Web Image Context Extraction (WICE) consists in obtaining the textual information describing an image using the content of the surrounding webpage. A common preprocessing step before performing WICE is to render the content of the webpage. When done at a large scale (e.g., for search engine indexation), it may become very computationally costly (up to several seconds per page). To avoid this cost, we introduce a novel WICE approach that combines Graph Neural Networks (GNNs) and Natural Language Processing models. Our method relies on a graph model containing both node types and text as features. The model is fed through several blocks of GNNs to extract the textual context. Since no labeled WICE dataset with ground truth exists, we train and evaluate the GNNs on a proxy task that consists in finding the semantically closest text to the image caption. We then interpret importance weights to find the most relevant text nodes and define them as the image context. Thanks to GNNs, our model is able to encode both structural and semantic information from the webpage. We show that our approach gives promising results to help address the large-scale WICE problem using only HTML data.

Diversity is a concept relevant to numerous domains of research varying from ecology, to information theory, and to economics, to cite a few. It is a notion that is steadily gaining attention in the information retrieval, network analysis, and artificial neural networks communities. While the use of diversity measures in network-structured data counts a growing number of applications, no clear and comprehensive description is available for the different ways in which diversities can be measured. In this article, we develop a formal framework for the application of a large family of diversity measures to heterogeneous information networks (HINs), a flexible, widely-used network data formalism. This extends the application of diversity measures, from systems of classifications and apportionments, to more complex relations that can be better modeled by networks. In doing so, we not only provide an effective organization of multiple practices from different domains, but also unearth new observables in systems modeled by heterogeneous information networks. We illustrate the pertinence of our approach by developing different applications related to various domains concerned by both diversity and networks. In particular, we illustrate the usefulness of these new proposed observables in the domains of recommender systems and social media studies, among other fields.

While graph-based collaborative filtering recommender systems have been introduced several years ago, there are still several shortcomings to deal with, the temporal information being one of the most important. The new link stream paradigm is aiming at extending graphs for correctly modelling the graph dynamics, without losing crucial information. We investigate the impact of such link stream features for recommender systems. We design link stream features, that capture the intrinsic structure and dynamics of the data. We show that such features encode a fine-grained and subtle description of the underlying system. We focused on a traditional recommender system context, the rating prediction on the MovieLens20M movie dataset and the Goodreads book dataset. We input link stream features along with some content-based ones into a gradient boosting machine (XGBoost) and show that itoutperforms significantly a sole content-based solution. These encouraging results call for further exploration of this original modelling and its integration to complete state-of-the-art recommender systems algorithms. Link streams and graphs, as natural visualizations of recommender systems, may offer more interpretability in a time when algorithm transparency is an increasingly important topic of discussion. We also hope that these results will sparkle interesting discussions in the community about the connections between link streams and traditional methods (matrix factorization, deep learning).

Music is a temporal organization of sounds, and we can therefore assume that any music representation has a structure that reflects some conceptual principles. This structure is hardly explicitly accessible in many encodings, such as, for instance, audio files. However, it appears much more clearly in the language of music notation.

              We propose to use the music notation language as a framework to model and manipulate the content of digital music objects, whatever their specific encoding may be. We describe an algebra that relies on this structured music representation to extract, restructure, and search such objects. The data model leverages the hidden structure of digital music encodings to enable powerful manipulations of their content.

              We apply the model to collections of music scores. We describe a system, based
              on an extension of XQuery with our algebra, that provides search,
              reorganization, and extraction functionalities on top of large collections of
              XML-encoded digital scores. Beyond its application to music objects, our work
              shows how one can rely on a structured content embedded in a complex XML
              encoding to develop robust collection management tools with minimal
              implementation effort.

A link stream is a collection of triplets (t, u, v) indicating
               that an interaction occurred between u and v at time t. Link streams model
               many real-world situations like email exchanges between individuals,
               connections between devices, and others. Much work is currently devoted to
               the generalization of classical graph and network concepts to link
               streams. In this paper, we generalize the existing notions of
               intra-community density and inter-community density. We focus on emails
               exchanges in the Debian mailing-list and show that threads of emails, like
               communities in graphs, are dense subsets loosely connected from a link
               stream perspective.

Scores are structured objects, and we can therefore envisage operations that change the structure of a score, combine several scores, and produce new score instances from some pre-existing material. Current score encodings, however, are designed for rendering and exchange purposes, and cannot directly be exploited as instances of a clear data model supporting algebraic manipulations. We propose an approach that leverages a music content model hidden in score notation, and define a set of composable operations to derive new "scores" from a corpus of existing ones. We show that this approach supplies a high-level tool to express common, useful applications, can easily be implemented on top of standard components, and finally gives rise to interesting conceptual issues related to the modeling of music notation.

Recent studies have shown that child abuse material is shared
              through peer-to-peer (P2P) networks, which allow users to exchange files
              without a central server. Obtaining knowledge on the extent of this
              activity has major consequences for child protection, policy making and
              Internet regulation. Previous works have developed tools and analyses to
              provide overall figures in temporally-limited measurements. Offenders’
              behavior is mostly studied through small-scale interviews and there is few
              information on the times at which they engage in such activity. Here we
              show that the proportion of search-engine queries for pedophile content
              gradually has grown by a factor of almost 3 in three years. We also find
              that during the day, certain hours are, on average, privileged by seekers.
              Our results demonstrate that P2P networks are actively used to search for
              pedophile content and we find new and large-scale results on pedophile
              offenders’ profile, indicating that a substantial proportion is
              well-integrated into family life and professional work activities.

Peer-to-peer (P2P) systems are widely used to exchange content
              over the Internet. Knowledge of pedophile activity in such networks remains
              limited, despite having important social consequences. Moreover, though
              there are different P2P systems in use, previous academic works on this
              topic focused on one system at a time and their results are not directly
              comparable. We design a methodology for comparing KAD and eDonkey, two P2P
              systems among the most prominent ones and with different anonymity levels.
              We monitor two eDonkey servers and the KAD network during several days and
              record hundreds of thousands of keyword-based queries. We detect
              pedophile-related queries with a previously validated tool and we propose,
              for the first time, a large-scale comparison of pedophile activity in two
              different P2P systems. We conclude that there are significantly fewer
              pedophile queries in KAD than in eDonkey (approximately 0.09% vs. 0.25%).

Peer-to-peer (P2P) networks are a popular method to exchange
               large volume of data through the Internet. Pedophile activity is a very
               important topic for our societies and some works have recently attempted
               to gauge the extent of pedophile exchanges on P2P networks. A key issue is
               to obtain an efficient detection tool, which may decide if a sequence of
               keywords is related to the topic or not. 

               We propose to use the analysis of the social network bipartite graph in a
               large dataset from a P2P network to improve a state-of-the-art filter for
               pedophile queries. We obtain queries and thus combinations of words which
               were not tagged by the filter but should be. We also perform some
               experiments to see if the original four categories of paedophile queries
               were observable by topological measures only.

We present a general formalism for Recommender Systems based on
               Social Network Analysis. After introducing the classical categories of
               recommender systems, we present our Social Filtering formalism and show
               that it extends association rules, classical Collaborative Filtering and
               Social Recommendation, while providing additional possibilities. This
               allows us to survey the literature and illustrate the versatility of our
               approach on various publicly available datasets, comparing our results
               with the literature.

Increasing knowledge of paedophile activity in P2P systems is a
               crucial societal concern, with important consequences on child protection,
               policy making, and internet regulation. Because of a lack of traces of P2P
               exchanges and rigorous analysis methodology, however, current knowledge of
               this activity remains very limited. We consider here a widely used P2P
               system, eDonkey, and focus on two key statistics: the fraction of
               paedophile queries entered in the system and the fraction of users who
               entered such queries. We collect hun- dreds of millions of keyword-based
               queries; we design a paedophile query detection tool for which we
               establish false positive and false negative rates using assessment by
               experts; with this tool and these rates, we then estimate the fraction of
               paedophile queries in our data; finally, we design and apply methods for
               quantifying users who entered such queries. We conclude that approximately
               0.25% of queries are paedophile, and that more than 0.2% of users enter
               such queries. These statistics are by far the most precise and reliable
               ever obtained in this domain.
