Felipe Moraes, Rodrygo L. T. Santos, Nivio Ziviani
2016 Text Retrieval Conference  
In TREC 2016, we focus on tackling the challenges posed by the Dynamic Domain (DD) track. The goal of the TREC DD track is to support research in dynamic, exploratory search within a complex domain.  ...  To this end, our participation investigates the suitability of multiple diversification approaches for dynamic information retrieval.  ...  INTRODUCTION The TREC 2016 Dynamic Domain (DD) track [5] consists of performing an interactive search task in a specific domain.  ...

Stochastic Metaheuristics as Sampling Techniques using Swarm Intelligence [chapter]

Johann Dreo, Patrick Siarry
2007 Swarm Intelligence, Focus on Ant and Particle Swarm Optimization  
They have the advantage of being generic methods, thus do not require a complex tuning for each problem, and can be used as a kind of "black boxes".  ...  Recall that, generally, optimization algorithms search for a point into the search space, so as to optimize (i.e., minimize or maximize) the objective function (also called fitness or goal function).  ...  This is typically a local search algorithm (for instance with the Nelder-Mead algorithm [45] or a taboo search). • Diversification aims at collecting new information, by exploring the search space.  ...

Toward the Integrated Framework Analysis of Linkages among Agrobiodiversity, Livelihood Diversification, Ecological Systems, and Sustainability amid Global Change

Karl Zimmerer, Steven Vanek
2016 Land  
The environmental impacts of livelihood interactions correspond to variation of diversification (migration, on-farm diversification) and resource system (i.e., agrobiodiversity per se, soil, water).  ...  We hypothesize these interactions depend on: (1) scope of livelihood diversification and type resource system; and (2) plant residues and above-/belowground component ecological specificity.  ...  For example, influential interactions occur within the human system influencing livelihood diversification.  ...

Coevolutionary dynamics of adaptive radiation for food-web development

Hiroshi C. Ito, Masakazu Shimada, Takashi Ikegami
2008 Population Ecology  
To investigate how complex food-webs can develop through repeated evolutionary diversification, a predator-prey model was analyzed.  ...  Predator-prey interactions among the phenotypes are determined by their relative positions in the phenotype space. Each phenotypic cluster was treated as a species.  ...  H.C.I. also thanks David Munro for inventing a tool for numerical analysis and visualization with great performance and flexibility, named Yorick, and distributing it for free.  ...

Discovery of Novel DENN Proteins: Implications for the Evolution of Eukaryotic Intracellular Membrane Structures and Human Disease

Dapeng Zhang, Lakshminarayan M. Iyer, Fang He, L. Aravind
2012 Frontiers in Genetics  
Thus, the origin of the longin domains from this ancient GTPase-interacting domain, concomitant with the radiation of GTPases, especially of the Rab clade, played an important role in the dynamics of eukaryotic  ...  The tripartite DENN module, comprised of a N-terminal longin domain, followed by DENN, and d-DENN domains, is a GDP-GTP exchange factor (GEFs) for Rab GTPases, which are regulators of practically all membrane  ...  For most searches a cut-off e-value of 0.01 was used to assess significance.  ...

Templated Search over Relational Databases

Anastasios Zouzias, Michail Vlachos, Vagelis Hristidis
2014 Proceedings of the 23rd ACM International Conference on Conference on Information and Knowledge Management - CIKM '14  
Primary reasons for this are dispersed data repositories, requirements for schema knowledge, and difficulties in using complex user interfaces.  ...  We show that the Templated Search paradigm renders the potentially complex underlying data sources intelligible and easily navigable.  ...  Scalable Greedy Diversification on Trees Now we show that the time complexity of the greedy algorithm (second row of Table 1 ) for solving Problem 3 on trees can be significantly improved.  ...
