KnoE:A Web Mining Tool to Validate Previously Discovered Semantic Correspondences

Journal of Computer Science & Technology 2012年第6期27卷 1222-1232页

The problem of matching schemas or ontologies consists of providing corresponding entities in two or more knowledge models that belong to a same domain but have been developed separately. Nowadays there are a lot of techniques and tools for addressing this problem, however, the complex nature of the matching problem make existing solutions for real situations not fully satisfactory. The Google Similarity Distance has appeared recently. Its purpose is to mine knowledge from the Web using the Google search engine in order to semantically compare text expressions. Our work consists of developing a software application for validating results discovered by schema and ontolog2/ matching tools using the philosophy behind this distance. Moreover, we are interested in using not only Google, but other popular search engines with this similarity distance. The results reveal three main facts. firstly, some web search engines can help us to validate semantic correspondences satisfactorily. Secondly there are significant differences among the web search engines. And thirdly the best results are obtained when using combinations of the web search engines that we have studied.

Phosphorus fractions and sorption dynamics in the sediments of two Ca-SO4 water reservoirs in the central Argentine Andes

引用

International Journal of Sediment Research 2017年第3期32卷 442-451页

作者： jos. Gabriel León fernando Luis Pedrozo Pedro félix Temporetti Instituto Argentino de Nivología Glaciología y Ciencias Ambientales (IANIGLA)CCT Mendoza Departamento General de Irrigación Gobierno de Mendoza Espaa y Barcala Instituto de Investigaciones en Biodiversidad y Medio Ambiente (INIBIOMA) CONICET-Universidad Nacional del Comahue

Phosphorus（P） fractionation and sorption behavior were studied in the sediments of two calcium-sulfate(Ca-SO4: Ca2+170 mg L-1; SO42-400 mg L-1) water reservoirs in the southern central Argentine Andes-El Carrizal Reservoir（ECR）,which stratifies in summer and El Nihuil Reservoir（ENR）,which is vertically mixed throughout the year. Sediment size classes reflected the lithology of both basins and the reservoirs relative location: ECR（downstream from a valley adjacent to a mountain environment） had higher clay proportions while the sand fraction was more important in ENR（just next to a mountain environment）.In both reservoirs, the chemical composition revealed low alteration and calcium enrichment. Total P content was relatively high(1.1-1.6 mg P kg-1dry weight) as expected from the contribution of marine formations. P fractionation was dominated by Ca-P（ECR, 69% and ENR, 63%） followed by organic-P（23%）in summer-anoxic ECR and by iron/aluminum（fe/Al）-P（27%） in oxic ENR. Batch experiments showed that sorption behavior in ECR had a typical Langmuir isotherm plot while in ENR that model fitted only at low dissolved P values(fe/Al-P content in anoxic（ECR） vs. oxic（ENR） sediments results from the P released from iron-bound phosphorus due to sulfate reduction-ferrous sulfide formation in an anoxic environment. This condition should enable ECR sediments to adsorb P into fresh oxidized iron,and ENR sediments to co-precipitate P with calcium due to fe/Al-P saturation, as observed in batch experiments. This paper constitutes the first description of phosphorus content and dynamics in reservoir sediments in arid central western Argentina, where water sulfate concentrations are naturally high due to basin lithology.

Effect of Homogenizing Procedures on the Properties of Reaction Sialon Suspension

厦门大学学报（自然科学版） 2002年第S1期41卷 132-133页

Homogeneous, high concentrated ceramic suspensions wi th low viscosity are the key controlling factors for the production of ceramic c omponents through colloidal processing. A well-dispersed suspension can be obta ined by choosing suitable dispersant, solvent, particle size distribution etc. B esides these factors, the homogenizing procedure is also a key step. In this paper, reaction sialon suspensions were prepared using 3-wt% KD1 as dis persant in organic media composed of 60-vol% methyletheylketone and 40-vol% et hanol. Different homogenizing procedures have been used and compared, including planetary milling, low energy ball milling and ultrasonic disaggregation. The ef fects of different homogenizing routes and mixing times on the rheology and stab ility of suspensions, and on the microstructure of slip casting green bodies, ha ve been studied. The varying dispersion efficiencies observed could be attribute d to differences in deagglomeration degrees achieved and in adsorption amount of dispersant onto the surface of reaction sialon powders.
