To bridge the vocabulary gap between the user’s information need and documents in a specific user generated content environment, the blogosphere, we apply a form of query expansion, i.e., adding and reweighing query terms. Since the blogosphere is noisy, query expansion on the collection itself is rarely effective but external, edited collections are more suitable. We propose a generative model...

Unlike traditional database management systems, in multimedia databases that support content-based retrieval over multimedia objects, it is di cult for users to express their exact information need directly in the form of a precise query. A typical interface supported by content-based retrieval systems allows users to express their query in the form of examples of objects similar to the ones th...

The main goal of this paper it is to present our experiments in ImageCLEF 2011 Campaign (Medical Retrieval Task). This edition we use textual and visual information, based on the assumption that the textual module better captures the meaning of a topic. So that, the TBIR module works firstly and acts as a filter, and the CBIR system reorder the textual result list. We also investigate if query ...

Humans can associate vision and language modalities and thus generate mental imagery, i.e. visual images, from linguistic input in an environment of unlimited inflowing information. Inspired by human memory, we separate a text-to-image retrieval task into two steps: 1) text-to-image conversion (generating visual queries for the 2 step) and 2) image-to-image retrieval task. This separation is ad...

Within this article, we sketch the set of generic tools we have devised and used within the summarization process and the domain of summary evaluation, focusing on how the tools were used within the TAC 2008 summarization update challenge. The tools have a common underlying theory and provide utility in various aspects of the Natural Language Processing domain. Within this study we elaborate on...

in this research the 2 sub verities of rhizopus oligosporus was used for production of antioxidative bioactive compounds from whey protein concentrate (wpc) and apple pomace. total phenolic compounds, free radical scavenging ability by dpph and antioxidant protection factort were evaluated in 48 determined treatments. effect of incubation temperature in three levels 23, 27, 31°c, incubation tim...

The synthesis and accumulation of RNA in Friend erythroleukemia (FL) cells induced to differentiate by treatment with the aminonucleoside of puromycin (AMS) or inhibited from differentiating by the addition of inosine to the medium were studied. When FL cells were grown in the presence of AMS, RNA synthesis was substantially inhibited. This effect could not be attributed solely to the inhibitio...

User-generated content on social websites such as Twitter is known to be an important source of real-time information on significant events as they occur, for example natural disasters. Our participation in the FIRE 2016 Microblog track, seeks to exploit WordNet as an external resource for synonym-based query expansion to support improved matching between search topics and the target Tweet coll...

This paper describes the participation of UAIC team at the ImageCLEF 2011 competition, Wikipedia Retrieval task. The aim of the task was to investigate retrieval approaches in the context of a large and heterogeneous collection of images and their noisy text annotations. We submitted a total of six runs, focusing our effort along the textual retrieval, query expansion on English language, combi...
