“ba:y?d” as a persian lexeme is interwoven with modality, a semantic category and therefore has a complicated and thought- provoking semantic nature. this paper uses evidence from persian to investigate the usage of this lexeme and some of its semantic and pragmatic aspects in this language. the results indicate that this lexical category can convey a wide range of modal meanings in different c...
Although the Semantic Web was originally designed as a “web for machines”, the growing wealth of information in Linked Open Data has become interesting for human users as well. Consequently, quite a few browsers for Linked Open Data have recently been developed. However, despite being developed for the semantic web, those browsers often present alphabetically ordered lists of facts, without res...
Collection of documents annotated with semantic entities and relationships are crucial resources to support development and evaluation of text mining solutions for the biomedical domain. Here I present an overview of 36 corpora and show an analysis on the semantic annotations they contain. Annotations for entity types were classified into six semantic groups and an overview on the semantic enti...
One of the most famous methods for recommendation is user-based Collaborative Filtering (CF). This system compares active user’s items rating with historical rating records of other users to find similar users and recommending items which seems interesting to these similar users and have not been rated by the active user. As a way of computing recommendations, the ultimate goal of the user-ba...
The research project MEDICO aims at developing an intelligent, robust and scalable semantic search engine for medical documents. The search engine of the MEDICO demonstrator RadSem is based on formal ontologies and is designated for different kinds of users, such as medical doctors, medical IT professionals, patients, and policy makers. Since semantic search results are not always self-explanat...
The idea of computer pattern recognition as applied to semantics has the same basic principles as the theory of the perception, which represents a sufficiently generalized model for that part of the brain whose function is classification, insofar as classification presupposes similarity between elements (or groups of elements) of the same class and difference between elements (or groups of elem...
The application of semantic technologies to the integration of biological data and the interoperability of bioinformatics analysis and visualization tools has been the common theme of a series of annual BioHackathons hosted in Japan for the past five years. Here we provide a review of the activities and outcomes from the BioHackathons held in 2011 in Kyoto and 2012 in Toyama. In order to effici...
Two components of verbal fluency performance--clustering (i.e., generating words within subcategories) and switching (i.e., shifting between subcategories)--were examined in patients with dementia of the Alzheimer type (DAT), patients with dementia with Parkinson's disease (DPD), nondemented patients with Parkinson's disease (NPD), and demographically matched controls. The DAT and DPD groups we...
OBJECTIVES To quantify semantic inconsistency in UMLS concepts from the perspective of their hierarchical relations and to show through examples how semantically-inconsistent concepts can help reveal erroneous synonymy relations. METHODS Inconsistency is defined in reference to concepts from the UMLS Metathesaurus. Consistency is evaluated by comparing the semantic groups of the two concepts ...
This study aimed to investigate the realizations of verbs’ syntactic and semantic features inmoves of applied linguistics research article introductions published in international andIranian local journals. To this end, a data of 30 research article introductions (15 published inIranian local journals and 15 in high impact international journals) was selected. The researcharticle introductions ...
