Learning and reasoning with graph data
Reasoning about graphs, and learning from graph data is a field of artificial intelligence that has recently received much attention in the machine learning areas of graph representation learning and graph neural networks. Graphs are also the underlying structures of interest in a wide range of more traditional fields ranging from logic-oriented knowledge representation and reasoning to graph kernels and statistical relational learning. In this review we outline a broad map and inventory of the field of learning and reasoning with graphs that spans the spectrum from reasoning in the form of logical deduction to learning node embeddings. To obtain a unified perspective on such a diverse landscape we introduce a simple and general semantic concept of a model that covers logic knowledge bases, graph neural networks, kernel support vector machines, and many other types of frameworks. Still at a high semantic level, we survey common strategies for model specification using probabilistic factorization and standard feature construction techniques. Based on this semantic foundation we introduce a taxonomy of reasoning tasks that casts problems ranging from transductive link prediction to asymptotic analysis of random graph models as queries of different complexities for a given model. Similarly, we express learning in different frameworks and settings in terms of a common statistical maximum likelihood principle. Overall, this review aims to provide a coherent conceptual framework that provides a basis for further theoretical analyses of respective strengths and limitations of different approaches to handling graph data, and that facilitates combination and integration of different modeling paradigms
Produkce diskurzu českých mluvčích s afázií: Explorace s využitím usage-based lingvistiky
The research in linguistic aphasiology has been dominated by structuralist, rule-based approaches to the study of langauge. However, recent work has shown that analyses based in constructivist, usage-based frameworks can provide explanations to patterns of language processing in aphasia that are difficult to accommodate in structuralist models. The present work follows up on these findings and aims to provide additional evidence for the benefits of the usage-based model by using data from Czech speakers with aphasia, an understudied language in this context. The aims of the study were threefold: to create a collection of samples of aphasic connected speech available to other researchers, to provide a description of the patterns of aphasic discourse production in Czech, and, most importantly, to show potential benefits of usage-based construction grammar for aphasia research. A corpus of the speech of eleven persons with fluent and non-fluent aphasia of varying degrees of severity was created. The corpus consist of more than 23000 word position produced by speakers with aphasia in tasks used to elicit conversational, narrative, descriptive, and procedural discourse. The corpus is lemmatized and morphologically tagged and the transcripts are aligned with audio recordings. A smaller sample of three,...Výzkum v lingvistické afaziologii využíval po dlouhou dobu především strukturalistické přístupy založené na pravidlech. Některé výsledky z poslední doby však ukazují, že konstruktivistické přístupy založené na užívání jazyka (usage-based přístup) dokážou vysvětlit některá specifika zpracování jazyka v afázii, která jsou ve strukturalistickém rámci obtížně vysvětlitelná. Předkládaná dizertační práce navazuje na tyto výzkumy a klade si za cíl předložit další důkazy pro výhodnost usage-přístupu. Využívá přitom data z češtiny, která je v afaziologickém výzkumu značně podreprezentovaná. Práce si stanovila tři cíle: jednak shromáždit projevy českých mluvčích s afázií, které by byly přístupné dalším výzkumníkům, dále podat detailní popis produkce diskurzu v afázii v češtině a konečně ukázat některé přednosti usage-based přístupu pro afaziologii. V rámci práce byl vytvořen korpus jedenácti mluvčích s fluentní a nefluentní afázií s různými stupni závažnosti poruchy. Korpus obsahuje přes 23000 slovních pozic vyprodukovaných mluvčími s afázií sebranými s využitím úkolů, jejichž cílem bylo elicitovat konverzační, narativní, deskriptivní a procedurální diskurz. Korpus je lematizován a morfologicky označkován. Dále je v něm zahrnut menší vzorek řečové produkce tří neurotypických mluvčích se srovnatelnými...Ústav českého jazyka a teorie komunikaceInstitute of Czech Language and Theory of CommunicationFaculty of ArtsFilozofická fakult
Ditransitives in germanic languages. Synchronic and diachronic aspects
This volume brings together twelve empirical studies on ditransitive constructions in Germanic languages and their varieties, past and present. Specifically, the volume includes contributions on a wide variety of Germanic languages, including English, Dutch, and German, but also Danish, Swedish, and Norwegian, as well as lesser-studied ones such as Faroese. While the first part of the volume focuses on diachronic aspects, the second part showcases a variety of synchronic aspects relating to ditransitive patterns. Methodologically, the volume covers both experimental and corpus-based studies. Questions addressed by the papers in the volume are, among others, issues like the cross-linguistic pervasiveness and cognitive reality of factors involved in the choice between different ditransitive constructions, or differences and similarities in the diachronic development of ditransitives. The volume’s broad scope and comparative perspective offers comprehensive insights into well-known phenomena and furthers our understanding of variation across languages of the same family
Optimizing scientific communication : the role of relative clauses as markers of complexity in English and German scientific writing between 1650 and 1900
The aim of this thesis is to show that both scientific English and German have become increasingly optimized for scientific communication from 1650 to 1900 by adapting the usage of relative clauses as markers of grammatical complexity. While the lexico-grammatical changes in terms of features and their frequency distribution in scientific writing during this period are well documented, in the present work we are interested in the underlying factors driving these changes and how they affect efficient scientific communication. As the scientific register emerges and evolves, it continuously adapts to the changing communicative needs posed by extra-linguistic pressures arising from the scientific community and its achievements. We assume that, over time, scientific language maintains communicative efficiency by balancing lexico-semantic expansion with a reduction in (lexico-)grammatical complexity on different linguistic levels. This is based on the idea that linguistic complexity affects processing difficulty and, in turn, communicative efficiency. To achieve optimization, complexity is adjusted on the level of lexico-grammar, which is related to expectation-based processing cost, and syntax, which is linked to working memory-based processing cost. We conduct five corpus-based studies comparing English and German scientific writing to general language. The first two investigate the development of relative clauses in terms of lexico-grammar, measuring the paradigmatic richness and syntagmatic predictability of relativizers as indicators of expectation-based processing cost. The results confirm that both levels undergo a reduction in complexity over time. The other three studies focus on the syntactic complexity of relative clauses, investigating syntactic intricacy, locality, and accessibility. Results show that intricacy and locality decrease, leading to lower grammatical complexity and thus mitigating memory-based processing cost. However, accessibility is not a factor of complexity reduction over time. Our studies reveal a register-specific diachronic complexity reduction in scientific language both in lexico-grammar and syntax. The cross-linguistic comparison shows that English is more advanced in its register-specific development while German lags behind due to a later establishment of the vernacular as a language of scientific communication.This work is supported by the Deutsche Forschungsgemeinschaft (DFG, German Research Foundation) –
