Language Processes and Related Statistics in the Posts Associated to Disasters on Social Networks

This paper provides a detailed and long-period statistics of the use of synonyms in posts related to specific events on social networks (SNs), an extended analysis of the correlations of the flows of the synonyms in such posts, a study of the applicability of Zipf’s law to posts related to specific events on SNs, and an analysis of the dynamics of the fluxes of synonyms in the posts. The paper also introduces the study of the distances in the phase space for the characterization of the dynamics of the word fluxes on social networks. This article is a partial report on recent research performed for a deeper analysis of social networks and of processes developing on social networks, including used lexicon, dynamics of messages related to a specific type of topic, and relationships of the processes on SNs with external events

Recognition and Prediction for Implicit Contrastive Focus in Romanian

This paper is made up of two parts: \textbf{the first part} continues the theoretical investigations on Information Structure (IS), linguistic, and computational approaches suitable to provide solutions to the prosody prediction problem of Implicit Contrastive Focus (ICF) concept, introduced in our previous papers. ICF is meant to be the particular case but also the counterpart of the classical category of contrastive Focus at the finite clause level, as the second item in the Background-Focus pair of IS dimension. The classical contrastive Focus, which we called Explicit Contrastive Focus (ECF), is the intonationally F marked entity introduced by overt lexical contrastive markers. ICF labels the situations where contrastive intonational focusation occurs but without the lexical presence of the contrastive Focus markers! The only and main device to introduce the contrastive focusation on certain constituents is the syntactic dislocation from their specific positions in the Systemic Ordering (SO) of syntactic-semantic roles for the Romanian finite clause. The ICF problem means to obtain reliable algorithms and procedures on the Discourse-Prosody interface in order to accurately predict the contrastive Focus distribution within the Romanian ICF-type affirmative finite clause. \textbf{The second, applicative part} of the paper describes algorithms for solving the ICF problem for Romanian, trying to exploit the typically dislocated constituents in the finite clause and to predict their Prosodic Prominence (PP). Procedures for the development of intonational-prosodic patterns assigned to the ICF distribution by certain ICF estimation schemes are developed and tested for a balanced set of Romanian ICF-type affirmative finite clauses

CoRoLa Starts Blooming – An update on the Reference Corpus of Contemporary Romanian Language

This article reports on the on-going CoRoLa project, aiming at creating a reference corpus of contemporary Romanian (from 1945 onwards), opened for online free exploitation by researchers in linguistics and language processing, teachers of Romanian, students. We invest serious efforts in persuading large publishing houses and other owners of IPR on relevant language data to join us and contribute the project with selections of their text and speech repositories. The CoRoLa project is coordinated by two Computer Science institutes of the Romanian Academy, but enjoys cooperation of and consulting from professional linguists from other institutes of the Romanian Academy. We foresee a written component of the corpus of more than 500 million word forms, and a speech component of about 300 hours of recordings. The entire collection of texts (covering all functional styles of the language) will be pre-processed and annotated at several levels, and also documented with standardized metadata. The pre-processing includes cleaning the data and harmonising the diacritics, sentence splitting and tokenization. Annotation will include morpho-lexical tagging and lemmatization in the first stage, followed by syntactic, semantic and discourse annotation in a later stage

Genetic analysis of 7 medieval skeletons from the Aragonese Pyrenees

Aim To perform a genetic characterization of 7 skeletons from medieval age found in a burial site in the Aragonese Pyrenees. Methods Allele frequencies of autosomal short tandem repeats (STR) loci were determined by 3 different STR systems. Mitochondrial DNA (mtDNA) and Y-chromosome haplogroups were determined by sequencing of the hypervariable segment 1 of mtDNA and typing of phylogenetic Y chromosome single nucleotide polymorphisms (YSNP) markers, respectively. Possible familial relationships were also investigated. Results Complete or partial STR profiles were obtained in 3 of the 7 samples. Mitochondrial DNA haplogroup was determined in 6 samples, with 5 of them corresponding to the haplogroup H and 1 to the haplogroup U5a. Ychromosome haplogroup was determined in 2 samples, corresponding to the haplogroup R. In one of them, the sub-branch R1b1b2 was determined. mtDNA sequences indicated that some of the individuals could be maternally related, while STR profiles indicated no direct family relationships. Conclusions Despite the antiquity of the samples and great difficulty that genetic analyses entail, the combined use of autosomal STR markers, Y-chromosome informative SNPs, and mtDNA sequences allowed us to genotype a group of skeletons from the medieval age

An Insight into the Corpus of Contemporary Romanian

This paper presents the almost final results of a priority project of the Romanian Academy – the Corpus of Contemporary Romanian Language (CoRoLa). The Corpus includes data in both written and spoken forms of the language. The textual collection is made up of publications covering the period from the 2nd World War to our days, while the spoken collection includes only recent recordings

Association between ancient bone preservation and DNA yield: A multidisciplinary approach

Ancient molecular typing depends on DNA survival in archaeological bones. Finding valuable tools to predict DNA presence in ancient samples, which can be measured prior to undertaking a genetic study, has become an important issue as a consequence of the peculiarities of archaeological samples. Since the survival of DNA is explained by complex interrelations of multiple variables, the aim of the present study was to analyze morphological, structural, chemical, and biological aspects of a set of medieval human bones, to provide an accurate reflection of the state of preservation of the bony components and to relate it with DNA presence. Archaeological bones that yielded amplifiable DNA presented high collagen content (generally more than 12%), low racemization values of aspartic acid (lesser than 0.08), leucine and glutamic acid, low infrared splitting factor, small size of crystallite, and more compact appearance of bone in the scanning electron micrographs. Whether these patterns are characteristic of ancient bones or specific of each burial site or specimen requires further investigation. © 2013 Wiley Periodicals, Inc.Grant sponsor: Estudio Antropológico y Genético de los Reyes Privativos de Aragón and Grupo Consolidado B44: Epidemiología Molecular from the Diputación General de Aragón (DGA), Spain..Peer Reviewe
