Ontology automatic enrichment consists of adding automatically new concepts and/or new relations to an initial ontology built manually using a basic domain knowledge. In a concrete manner, enrichment is firstly, extracting concepts and relations from textual sources then putting them in their right emplacements in the initial ontology. However, the main issue in that process is how to preserve ...

This paper demonstrates and systematically characterizes the enrichment of biomolecular compounds using aptamer-functionalized surfaces within a microfluidic device. The device consists of a microchamber packed with aptamer-functionalized microbeads and integrated with a microheater and temperature sensor to enable thermally controlled binding and release of biomolecules by the aptamer. We firs...

Modularity Conserved during Evolution: Algorithms and Analysis by Luqman Hodgkinson Doctor of Philosophy in Computer Science with Designated Emphasis in Computational and Genomic Biology University of California, Berkeley Professor Richard M. Karp, Chair Modularity is a defining feature of biological systems. This dissertation presents our work on the development of algorithms to detect modular...

Texts are replete with gaps, information omitted since authors assume a certain amount of background knowledge. We define the process of enrichment that fills these gaps. We describe how enrichment can be performed using a Background Knowledge Base built from a large corpus. We evaluate the effectiveness of various openly available background knowledge bases and we identify the kind of informat...

The enrichment of the intergalactic medium with heavy elements is a process that lies at the nexus of poorly-understood aspects of physical cosmology. We review current understanding of the processes that may remove metals from galaxies, the basic predictions of these models, the key observational constraints on enrichment, and how intergalactic enrichment may be used to test cosmological simul...

the influence of 0-27 g/100g of full-fat soy flour (ffsf), 31-35g/100g of water content and extrusion conditions on the textural characteristics of spaghetti were evaluated. process was performed with screw speed of 10-40 rpm and water circulating temperature of 35-70°c. this enrichment resulted in significant differences in mechanical strength and cutting parameter. based on the mixture surfac...

I show that recent observations of r-process abundances in metal-poor stars are difficult to explain if neutron star mergers (NSMs) are the major r-process sources. In contrast, such observations and meteoritic data on 182Hf and 129I in the early solar system support a self-consistent picture of r-process enrichment by supernovae (SNe). While further theoretical studies of r-process production ...

The question answering systems are considered the next generation of search engines. This paper focuses on the first step of this process, which is to search for relevant passages containing answers. Passage Retrieval, can be difficult because of the complexity of data, log files in our case. Our contribution is based on the enrichment of queries by using a learning method and a novel term weig...

Organizations have an increasing need to adapt faster their Information Systems (IS) to technical, functional or legal changes. Orange, a French telecom operator, works on the adaptation and the improvement of their business processes (BP), especially those related to Customer Relationship Management (CRM). One of the challenges is to help a business expert to efficiently and quickly adapt a BP...
