The goal of this research is to clarify the role of document classification in information filtering. An important function of classification, in managing computational complexity, is described and illustrated in the context of an existing filtering system. A parameter called classification homogeneity is presented for analyzing unsupervised automated classification by employing human classific...

OBJECTIVES To explore automatic methods for the classification of biomedical vocabularies based on their content. METHODS We create semantic group profiles for each source vocabulary in the UMLS and compare the vectors using a Euclidian distance. We explore several techniques for visualizing individual semantic group profiles and the entire distance matrix, including donut pie charts, heatmap...

Computer science is undergoing a profound transformation: gains in computing power and the availability of large datasets provide a fertile ground for machine learning research. One challenge in this context is to take account of user preferences to provide personalized access to information.Recommender systems create user and item profiles using past user reviews, profiles that reflect user pr...

An interoperation study, WellnessRules, is described, where rules about wellness opportunities are created by participants in rule languages such as Prolog and N3, and translated within a wellness community using RuleML/XML. The wellness rules are centered around participants, as profiles, encoding knowledge about their activities conditional on the season, the time-of-day, the weather, etc. Th...

We describe a new representation of the content vocabulary of a text we call word association profile that captures the proportions of highly associated, mildly associated, unassociated, and dis-associated pairs of words that co-exist in the given text. We illustrate the shape of the distirbution and observe variation with genre and target audience. We present a study of the relationship betwee...

this study aims at investigating a sexual vocabulary in qur’an, by clarriffaying ephemestic styles, adopted in “qur’an”, to refer to the taboo vocabulary, the study depends on “kashaaf” of “al zamakhshary”. the study results in the facts that sexual vocabulary, from the majority of the taboo words. these vocabularies may have close or distint meaning in relation to the taboo words. thus, the me...

most of the studies on the key word method of second/foreign language vocabulary learning have been based on the evidence from laboratory experiments and have primarily involved the use of english key words to learn the vocabularies of other languages. furthermore, comparatively quite limited number of such studies is done in authentic classroom contexts. the present study inquired into the eff...

Capturing clinical observations and findings during the diagnostic imaging process is increasingly becoming a critical step in diagnostic reporting. Standards developers—notably HL7 and DICOM—are making significant progress toward standards that enable exchanging clinical observations and findings among the various information systems of the healthcare enterprise. DICOM—like the HL7 Clinical Do...

CASRAI and CERIF are international standardisation initiatives in the domain of Research Information Management. CASRAI develops and maintains a standard extensible vocabulary and exchangeable data profiles that reflect the business requirements of involved stakeholders. A data profile specifies the maximal ideal space of its application with compliant data records. CERIF is a data model supply...
