URI Disambiguation in the Context of Linked Data
No full textThe Linked Data initiative has given rise to an increasing number of RDF datasets, many of which are freely accessible online. These resources often arise as a result of database exports; however sufficient consideration may not be given to the unseen implications caused when they are used in the wider context of the Semantic Web. This paper investigates two popular resources, DBLP and DBpedia, and discusses whether the issues regarding identity management and co-reference resolution have been suitably addressed. We find that a large percentage of authors in DBLP have been conflated, and that disambiguation pages have been incorrectly linked using owl:sameAs within DBpedia. Systems for dealing with these issues are presented, and directions are given for future research
Glaser-Mediated Synthesis and Photophysical Characterization of Diphenylbutadiyne-Linked Porphyrin Dyads
No full textThe Pd-mediated Glaser coupling of a zinc monoethynyl porphyrin and a magnesium monoethynyl
porphyrin affords a mixture of three 4,4‘-diphenylbutadiyne-linked dyads comprised of two zinc
porphyrins (Zn-pbp-Zn), two magnesium porphyrins (Mg-pbp-Mg), and one metalloporphyrin of
each type (Zn-pbp-Mg). The latter is easily isolated due to the greater polarity of the magnesium
versus the zinc chelate. Exposure of Zn-pbp-Mg to silica gel results in selective demetalation,
affording Zn-pbp-Fb where Fb = free base porphyrin. This synthesis route employs the magnesium
porphyrin as a latent form of the Fb porphyrin, thereby avoiding copper insertion during the Glaser
reaction, and as a polar entity facilitating separation. The absorption spectrum of Zn-pbp-Mg or
Zn-pbp-Fb is the sum of the spectra of the component parts, while in each case the fluorescence
spectrum upon illumination of the Zn porphyrin is dominated by emission from the Mg or Fb
porphyrin. Time-resolved absorption spectroscopy shows that the energy-transfer rate constants
are (11 ps)-1 and (37 ps)-1 for Zn-pbp-Mg and Zn-pbp-Fb, respectively, corresponding to energy-transfer quantum yields of 0.995 and 0.983, respectively. The calculated Förster through-space
rates are (1900 ps)-1 and (1100 ps)-1 for Zn-pbp-Mg and Zn-pbp-Fb, respectively. Accordingly,
the through-bond process dominates for both dyads with a through-bond:through-space energy-transfer ratio of ≥97:1. Collectively, the studies show that the 4,4‘-diphenylbutadiynyl linker
supports fast and efficient energy transfer between Zn and Mg or Fb porphyrins
Cantiche e Nuvole. Mattotti, Glaser, Moebius e la Commedia Nuages
No full textAlla fine degli anni Novanta, Cristina Taverna, fondatrice della galleria milanese Nuages, concepisce il progetto di una nuovissima Commedia illustrata. Un progetto ambizioso, che viene pubblicato nel 1999, sempre da Nuages, nella collana ‘I classici illustrati’. Le immagini vengono commissionate a tre maestri assoluti del fumetto e della grafica: Lorenzo Mattotti, Milton Glaser, Jean Giraud (Moebius). Nella diversità assoluta, vengono presentate soluzioni creative, iconografiche e tecniche radicalmente differenti: pastello, materia, larghi volumi e sintetiche geometrie con Mattotti, rarefatti monotipi pierfrancescani e simbolisti con Glaser, tenui acquerelli su carte da ricalco con Moebius. Il risultato è una lettura inedita e imprevedibile, che raccoglie e distilla, con tre modalità differenti, una storia plurisecolare e che si pone, alla chiusura del secondo millennio, come una summa ideale dell’illustrazione dantesca.

Also By The Same Author: AKTiveAuthor, a Citation Graph Approach to Name Disambiguation
No full textThe desire for definitive data and the semantic web drive for inference over heterogeneous data sources requires co-reference resolution to be performed on those data. In particular, name disambiguation is required to allow accurate publication lists, citation counts and impact measures to be determined. This paper describes a graph-based approach to author disambiguation on large-scale citation networks. Using self-citation, co-authorship and document source analyses, AKTiveAuthor clusters papers, achieving precision of 0.997 and recall of 0.818 over a test group of eight surname clusters

No full textA comparison of critical thinking skills for hospitality management graduates from associate and baccalaureate degree programs
Full text linkPlan BIt has been suggested that the university and college hospitality management programs must change their programs to meet the needs of the industry. To that end, the four-year Baccalaureate Degree institutions should produce graduates prepared for upper level management position and the two-year programs should prepare graduates for operations management positions. If the hospitality industry desires graduates with "critical thinking skills," then the institutions have a responsibility to not only incorporate these skills into the curriculum but test the graduates in the end to insure that they do indeed possess these skills. The purpose of this study was to acquire information concerning the critical thinking skills of hospitality management graduates in both Associate and Baccalaureate Degree programs. The primary focus is on the overall critical thinking skills of graduates from these two levels of education. This study compared the critical thinking skills of hospitality management graduates in both Associate Degree and Baccalaureate Degree Programs. The hypothesis is: “The critical thinking skills of Associate and Baccalaureate Degree graduates in hospitality management as rated by the Watson-Glaser Critical Thinking Appraisal are similar.” This study clearly shows that there is no significant statistical difference between the associate degree and baccalaureate degree graduates in hospitality management programs
Managing Co-reference on the Semantic Web
No full textCo-reference resolution, or the determination of ‘equivalent’ URIs referring to the same concept or entity, is a significant hurdle to overcome in the realisation of large scale Semantic Web applications. However, it has only recently gained the attention of research communities in the Semantic Web context, and while activities are now underway in identifying co-referent or conflated URIs, little consideration has been given to tools and techniques for storing, manipulating, and reusing co-reference information. This paper provides an overview of the specification, implementation, interactions and experiences in using the Co-reference Resolution Service (CRS)to facilitate rigorous management of URI co-reference data, and enable interoperation between multiple Linked Open Data sources. Comparisons are made throughout the paper contrasting the differences in the way the CRS manages multiple URIs for the same resource with the emerging practice of using owl:sameAs to identify duplicate URIs. The advantages and benefits that have been gained from deploying the CRS on a site with multiple Linked Data repositories are also highlighted
