Do We Need Improved Code Quality Metrics?
Tushar Sharma, Diomidis Spinellis
The software development community has been using code quality metrics for the last five decades. Despite their wide adoption, code quality metrics have attracted a fair share of c…
The Software Heritage Graph Dataset: Large-scale Analysis of Public Software Development History
Antoine Pietri, Diomidis Spinellis, Stefano Zacchiroli
Software Heritage is the largest existing public archive of software source code and accompanying development history. It spans more than five billion unique source code files and…
Bayesian inference for transportation origin-destination matrices: the Poisson-inverse Gaussian and other Poisson mixtures
Konstantinos Perrakis, Dimitris Karlis, Mario Cools +1
In this paper we present Poisson mixture approaches for origin-destination (OD) modeling in transportation analysis. We introduce covariate-based models which incorporate different…
Search Engine Similarity Analysis: A Combined Content and Rankings Approach
Konstantina Dritsa, Thodoris Sotiropoulos, Haris Skarpetis +1
How different are search engines? The search engine wars are a favorite topic of on-line analysts, as two of the biggest companies in the world, Google and Microsoft, battle for pr…
Modelling of functional profiles and explainable shape shifts detection: An approach combining the notion of the Fréchet mean with the shape invariant model
Georgios I. Papayiannis, Stelios Psarakis, Athanasios N. Yannacopoulos
A modelling framework suitable for detecting shape shifts in functional profiles combining the notion of Fréchet mean and the concept of deformation models is developed and propose…
GREEK-BERT: The Greeks visiting Sesame Street
John Koutsikakis, Ilias Chalkidis, Prodromos Malakasiotis +1
Transformer-based language models, such as BERT and its variants, have achieved state-of-the-art performance in several downstream natural language processing (NLP) tasks on generi…
Truthful Equilibria in Generalized Common Agency Models
Ilias Boultzis
In this paper I discuss truthful equilibria in common agency models. Specifically, I provide general conditions under which truthful equilibria are plausible, easy to calculate and…
Closed Non-atomic Resource Allocation Games
Costas Courcoubetis, Antonis Dimakis
How is efficiency affected when demand excesses over supply are signalled through waiting in queues? We consider a class of congestion games with a nonatomic set of players of a co…
Identifying Bugs in Make and JVM-Oriented Builds
Thodoris Sotiropoulos, Stefanos Chaliasos, Dimitris Mitropoulos +1
Incremental and parallel builds are crucial features of modern build systems. Parallelism enables fast builds by running independent tasks simultaneously, while incrementality save…
Infinite mixtures of multivariate normal-inverse Gaussian distributions for clustering of skewed data
Yuan Fang, Dimitris Karlis, Sanjeena Subedi
Mixtures of multivariate normal inverse Gaussian (MNIG) distributions can be used to cluster data that exhibit features such as skewness and heavy tails. However, for cluster analy…
On the identifiability of Bayesian factor analytic models
Panagiotis Papastamoulis, Ioannis Ntzoufras
A well known identifiability issue in factor analytic models is the invariance with respect to orthogonal transformations. This problem burdens the inference under a Bayesian setup…
Speaker-change Aware CRF for Dialogue Act Classification
Guokan Shang, Antoine Jean-Pierre Tixier, Michalis Vazirgiannis +1
Recent work in Dialogue Act (DA) classification approaches the task as a sequence labeling problem, using neural network models coupled with a Conditional Random Field (CRF) as the…
Power-Expected-Posterior Priors as Mixtures of g-Priors
Dimitris Fouskakis, Ioannis Ntzoufras
One of the main approaches used to construct prior distributions for objective Bayes methods is the concept of random imaginary observations. Under this setup, the expected-posteri…
A Dataset of Enterprise-Driven Open Source Software
Diomidis Spinellis, Zoe Kotti, Konstantinos Kravvaritis +2
We present a dataset of open source software developed mainly by enterprises rather than volunteers. This can be used to address known generalizability concerns, and, also, to perf…
A Complete Set of Related Git Repositories Identified via Community Detection Approaches Based on Shared Commits
Audris Mockus, Diomidis Spinellis, Zoe Kotti +1
In order to understand the state and evolution of the entirety of open source software we need to get a handle on the set of distinct software projects. Most of open source project…
A Dataset for GitHub Repository Deduplication: Extended Description
Diomidis Spinellis, Zoe Kotti, Audris Mockus
GitHub projects can be easily replicated through the site's fork process or through a Git clone-push sequence. This is a problem for empirical software engineering, because it can…
