The paper starts with an overview of major problems hindering effective interactions with information retrieval systems. A brief review of models of the interaction taking place during information seeking is then provided with the aim of lying the ground for yet another model based on two levels of interaction: presentation and navigation. The former encompasses interactions with the user inter...

Ontology as a knowledge base can provide different reasoning tasks, e.g. to check consistency of the ontology or to check whether a resource is instance of a concept or not. In this paper we want to focus on retrieval problem. There already exist systems resolving this problem, but they are not effective within large datasets. Our idea is to transform ontology into a relational database. We pre...

Background Severe ovarian bleeding after transvaginal oocyte retrieval is a rare but potentially life-threatening complication. A late-onset is common and may be associated with an increased risk for ovariectomy. In the present study we analyzed our cases of ovarian bleeding (OB) after oocyte retrieval and compared it with the published cases and studies, including 31 patients. Main outcome mea...

The model was designed in such a way that it may support both traditional archive access services and advanced access services. The first category of services allows the retrieval of audio-visual documents by using descriptive fields about the content or the physical copy of the resource (e.g. name of the producer, title of the series, the tape collocation). The second category of services allo...

Retrieval of resources semantically annotated is a problem that is gaining interest as more and more documents and services expose descriptions based on languages developed in the framework of Semantic Web. In a semanticenabled resource retrieval process, given a request, a ranking of compatible resources should be provided. Obviously having semantically annotated resources, the ranking sholud ...

In large-scale distributed retrieval, challenges of latency, heterogeneity, and dynamicity emphasise the importance of infrastructural support in reducing the development costs of state-of-the-art solutions. We present a service-based infrastructure for distributed retrieval which blends middleware facilities and a design framework to ‘lift’ the resource sharing approach and the computational s...

Sentences extracted from Twitter have been seen as a valuable resource for response generation in dialogue systems. However, selecting appropriate ones is difficult due to their noise. This paper proposes tackling such noise by syntactic filtering and content-based retrieval. Syntactic filtering ascertains the valid sentence structure as system utterances, and content-based retrieval ascertains...

To realize the vision of the Semantic Web, effective techniques of Information Retrieval need to be developed. Ranking the results of a search is one of the main challenges of an Information Retrieval system. In this paper we present a technique for ranking the results of a Semantic Web query. The ranking is based on various factors including the Semantic Web resource importance. We have modifi...

the central cholinergic system has been associated with cognitive function and memory and acetylcholine plays an important role during the early stages of memory consolidation. in this study, after training mice were tested with one way active avoidance procedure and retention were tested at 4, 8, 12, 16 and 24 hours of training and compared with non-shocked mice, in which it took 24 hours, a s...
