This paper summarizes the participation of UNED at the 2014 Retrieving Diverse Social Images Task [3]. We propose a novel approach based on Formal Concept Analysis (FCA) to detect the latent topics related to the images and a later Hierarchical Agglomerative Clustering (HAC) to put together the images according to these latent topics. The diversification will be based on offering images from th...

the visual form of writing has not only meaning apart from the content of writing but also different language from the language of writing. based on this claim, graphologists believe that it is possible to recognize writers’ thought through their handwriting. in fact, graphologists constituted some principles for analyzing handwriting as well as semiotic system for interpreting the visual diver...

In web search scenario, users often submit short query terms to search engines, expecting to find their desired information in top ranked results. But their queries are so ambiguous that their actual information needs are often unspecified. To satisfy the different information needs, an effective approach is to diversify the top results retrieved for the query. In this paper, we reduce the dive...

The demand that anatomical structures work together to perform biological functions is thought to impose strong limits on morphological evolution. Breakthroughs in diversification can occur, however, when functional integration among structures is relaxed. Although such transitions are expected to generate variation in morphological diversification across the tree of life, empirical tests of th...

The present study attempts to link plant-level production diversification to productivity growth in Taiwan’s electronics industry. An account of the role of the Taiwanese government over the last 2 decades leading to the take-off of its electronics industry is briefly discussed. We reviewed production activities of more than 20 000 Taiwanese electronics plants during the period 1992–1999. In an...

Many important questions in developmental biology increasingly interface with related questions in other biological disciplines such as evolutionary biology and ecology. In this article, we review and summarize recent progress in the development of horned beetles and beetle horns as study systems amenable to the integration of a wide range of approaches, from gene function analysis in the labor...

abstract the industrial dairy farms in iran are facing several economic problems and about six percent of these farms were shut down in fars province due to low profitability. despite such problems and availability of other enterprises in the region, farmers do not switch to other farm activities. in this context, the factors affecting acceptance of diversification options were investigated in ...
