Learning the Language of Biological Sequences

International audienceLearning the language of biological sequences is an appealing challenge for the grammatical inference research field.While some first successes have already been recorded, such as the inference of profile hidden Markov models or stochastic context-free grammars which are now part of the classical bioinformatics toolbox, it is still a source of open and nice inspirational problems for grammatical inference, enabling us to confront our ideas to real fundamental applications. As an introduction to this field, we survey here the main ideas and concepts behind the approaches developed in pattern/motif discovery and grammatical inference to characterize successfully the biological sequences with their specificities

Construction morphology:issues in Akan complex nominal morphology

Akan, like any other language, has both regular and irregular complex nominals (CNs). However, previous studies of Akan nominals have been constructive in approach, mostly adhering to a strict form of the principle of compositionality and assuming that the morphological, phonological and semantic properties of CNs can be accounted for fully by tweaking those of their constituents. Consequently, CNs whose properties cannot be so accounted for are either ignored or forced into the mould of regular ones. In this study, I do three things. First, I present a detailed empirically-based assessment of attested CNs in Akan based on a dataset of 1000 CNs drawn from a variety of written sources. This shows that Akan CNs may be grouped into four; compounds, affix-derived CNs, those formed by tonal changes and “lexicalized” forms, which have the form of phrases but occur as CNs and are mostly only partially compositional. Secondly, I present a detailed discussion of the formal and semantic properties of all the attested compounds and a subset of the lexicalized nominals. Thirdly, on the basis of the latter discussion, I examine what the formation and structure of CNs reveal about the interaction between morphology and syntax and about the architecture of the grammar. The analyses show that the formation of CNs in Akan may at once involve morphological and syntactic structure in a way that renders untenable the view that morphology and syntax constitute two completely different modules of the grammar which may be assumed to interact only because the output of the former is the input to the latter. The present study provides support for the constructional view of the grammar

After Conversion

This book deals with the religious and ideological consequences of mass conversion in Iberia - where Jews and Muslims were forcibly converted or expelled at the end of the XVth century and beginning of the XVIth- and most specially with the relationship between origins and faith. It also deals with the consequences of coercion on intellectual debates and on the production of knowledge and addresses questions such as dissimulation, dissidence, religious doubt and unbelief
