a r t i c l e i n f o Recent research trends in Content-based Video Retrieval have shown topic models as an effective tool to deal with the semantic gap challenge. In this scenario, this paper has a dual target: (1) it is aimed at studying how the use of different topic models (pLSA, LDA and FSTM) affects video retrieval performance; (2) a novel incre-mental topic model (IpLSA) is presented in ...

This paper addresses the problem of constructing a semantic hierarchy for a machine translation system. We propose two methods of constructing a hierarchy: acquiring a hierarchy from scratch and updating a hierarchy. When acquiring a hierarchy from scratch, translation rules are learned by an inductive learning algorithm in the rst step. A new hierarchy is then generated by applying a clusterin...

Résumé. Les approches existantes pour structurer automatiquement un flux de télévision (i.e. reconstituer un guide de programme exact et complet), sont supervisées. Elles requièrent de grandes quantités de données annotées manuellement, et aussi de définir a priori les types d’émissions (publicités, bandes annonces, programmes, sponsors...). Pour éviter ces deux contraintes, nous proposons une ...

This paper introduces an expressive class of indexed quotient-inductive types, called QWI within the framework constructive type theory. They are initial algebras for families equational theories with possibly infinitary operators and equations. We prove that types can be derived from quotient inductive in theory toposes natural number object universes, provided those universes satisfy Weakly I...

abstract background: being a nurse is more than just a series of business activities and skills. in fact, it is a part of the process of socialization, which is internalization and development of professional identity. professional socialization is necessary for involving the students in professional practices. thus, the purpose of this qualitative research was to increase the understanding of ...

background: male infertility accounts for 30-50% of all infertilities among couples. iranian traditional medicine (itm) stressed the importance of nutrition in the prevention and treatment of male infertility. many iranian traditional physicians have described the traits of specific foods for prevention and treatment of male infertility. objective: to explore the principles and roles of foods r...

We present analytic and numerical results for two models, namely the minority model and the bar-attendance model, which offer simple paradigms for a competitive marketplace. Both models feature heterogeneous agents with bounded rationality who act using inductive reasoning. We find that the effects of crowding are crucial to the understanding of the macroscopic fluctuations, or ‘volatility’, in...

This paper presents a novel idea to the problem of learning concept descriptions from examples. Whereas most existing approaches rely on a large number of classiied examples, the approach presented in the paper is aimed at being applicable when only a few examples are classiied as positive (and negative) instances of a concept. The approach tries to take advantage of the information which can b...
