Cross-linguistically, it is commonly expressed by the use of (i) demonstratives including both demonstrative pronouns and demonstrative adjectives, (ii) deictic adverbs of space, (iii) deictically marked third-person pronouns, and (iv) deictic directionals including both motion affixes, morphemes and particles, and motion verbs. In this article, I shall provide a descriptive analysis of the grammaticalization and lexicalization of space deixis. Data is drawn from a wide variety of genetically unrelated and structurally distinct languages to show the diversity and richness of spatial deictic systems in the world’s languages.展开更多

This higher level of granularity is worldwide spread under the umbrella of several national modifications named ICD10 XM. These developments have met the increased use of the International Clinical Reference Terminology named SNOMED. When the updating of WHO ICD10 to WHO ICD11 was decided a merging was envisaged and a WHO SNOMED CT common work proposed a methodology to create a common formal ontology between the 11th version of the WHO International Classification of Diseases and Health Problems (ICD) and the most used in the world clinical terminology named Systematized Nomenclature of Human and Veterinary Medicine - Clinical Terms (SCT). The present work follows this unachieved work and aims to develop a SNOMED-based formal ontology for ICD11 chapter 1 using the textual definitions of ICD11 codes which is a completely new character of ICD and the ontology tools provided by SCT in the publicly available SNOMED Browser. There are two key results: the lexical alignment is complete and the ontology alignment is incomplete with the validated SNOMED concept model can be completed with not yet validated attributes and values of the SNOMED Compositional Grammar. The work opens a new era for the seamless use of both international terminologies for morbidity for instance for DRG/Casemix and clinical management use. The main limitation is that it is restricted to 1 out of 26 chapters of ICD11.展开更多

[Method] By introducing cloud model into stochastic grammar model, a machine learning algorithm suitable for the lexicalized stochastic grammar model was proposed. The word grid mode was used to extract and divide RNA sequence to acquire lexical substring, and the cloud classifier was used to search the maximum probability of each lemma which was marked as a certain sec- ondary structure type. Then, the lemma information was introduced into the training stochastic grammar process as prior information, realizing the prediction on the sec- ondary structure of RNA, and the method was tested by experiment. [Result] The experimental results showed that the prediction accuracy and searching speed of stochastic grammar cloud model were significantly improved from the prediction with simple stochastic grammar. [Conclusion] This study laid the foundation for the wide application of stochastic grammar model for RNA secondary structure prediction.展开更多

文摘Space deixis is concerned with the specification of location in space relative to that of the participants at coding time in a speech event. Cross-linguistically, it is commonly expressed by the use of (i) demonstratives including both demonstrative pronouns and demonstrative adjectives, (ii) deictic adverbs of space, (iii) deictically marked third-person pronouns, and (iv) deictic directionals including both motion affixes, morphemes and particles, and motion verbs. In this article, I shall provide a descriptive analysis of the grammaticalization and lexicalization of space deixis. Data is drawn from a wide variety of genetically unrelated and structurally distinct languages to show the diversity and richness of spatial deictic systems in the world’s languages.
