This book collects research contributions concerning quantitative approaches to characterize originality and universality in language. The target audience comprises researchers and experts in the field but the book may also be beneficial for graduate students. Creativity might be considered as a morphogenetic process combining universal features with originality. While quantitative methods applied to text and music reveal universal features of language and music, originality is a highly appreciated feature of authors, composers, and performers. In this framework, the different methods of traditional problems of authorship attribution and document classification provide important insights on how to quantify the unique features of authors, composers, and styles. Such unique features contrast, and are restricted by, universal signatures, such as scaling laws in word-frequency distribution, entropy measures, long-range correlations, among others. This interplay between innovation and universality is also an essential ingredient of methods for automatic text generation. Innovation in language becomes relevant when it is imitated and spread to other speakers and musicians. Modern digital databases provide new opportunities to characterize and model the creation and evolution of linguistic innovations on historical time scales, a particularly important example of the more general problem of spreading of innovations in complex social systems. This multidisciplinary book combines scientists from various different backgrounds interested in quantitative analysis of variations (synchronic and diachronic) in language and music. The aim is to obtain a deeper understanding of how originality emerges, can be quantified, and propagates.

This book constitutes the refereed proceedings of the 13th International Conference of the CLEF Association, CLEF 2022, held in Bologna, Italy in September 2022.The conference has a clear focus on experimental information retrieval with special attention to the challenges of multimodality, multilinguality, and interactive search ranging from unstructured to semi structures and structured data. The 7 full papers presented together with 3 short papers in this volume were carefully reviewed and selected from 14 submissions. This year, the contributions addressed the following challenges: authorship attribution, fake news detection and news tracking, noise-detection in automatically transferred relevance judgments, impact of online education on children's conversational search behavior, analysis of multi-modal social media content, knowledge graphs for sensitivity identification, a fusion of deep learning and logic rules for sentiment analysis, medical concept normalization and domain-specific information extraction. In addition to this, the volume presents 7 "best of the labs" papers which were reviewed as full paper submissions with the same review criteria. 14 lab overview papers were accepted and represent scientific challenges based on new datasets and real world problems in multimodal and multilingual information access.

Questo libro ha lo scopo di familiarizzare gli studenti con aspetti anche abbastanza moderni della teoria dei sistemi dinamici facendo quasi del tutto a meno dell'apparato matematico di analisi, algebra e geometria. L'uso della simulazione numerica al calcolatore, sempre piu importante nello studio dei sistemi dinamici, costituisce parte integrante di questo processo. Oltre ad abituare fin da subito gli studenti a mettere le mani sul calcolo scientifico, si mira a far si che la presentazione di questi argomenti possa contribuire a due ulteriori processi formativi di sicuro valore: da una parte, vedere nascere in modo quasi spontaneo concetti matematici profondi e sottili e vederli all'opera nel concreto; dall'altra abituarsi fin da subito a lavorare con la matematica per analizzare quantitativamente le scienze della natura.

Il libro e rivolto agli studenti dei corsi di laurea in matematica, fisica, biologia, ingegneria, ma anche economia, informatica e scienze della comunicazione."
