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

Semiometrics: Applying Ontologies across Large-Scale Digital Libraries
No full textAs large-scale digital libraries become more available and complete, not to mention more numerous, it is clear there is a need for services that can draw together and perform inference calculations on the metadata produced. However, the traditional Relational Database Management System (RDBMS) model, while efficiently constructed and optimised for many business structures, does not necessarily cope well with issues of concurrent data updates and retrieval at the scale of hundreds of thousands of papers. At the same time the growth of RDF and the increasing interest in Semantic Web technologies perhaps begins to present a viable alternative at a scalable, practical level. This paper considers a specific application of large-scale metadata analysis and conducts scalability tests using real-world data. It concludes that RDF technologies are both a scalable and performance-realistic alternative to traditional RDBMS approaches. It also shows that for relationship-based queries on large-scale metadata stores, RDF technologies can significantly out-perform traditional RDBMS approaches by allowing both retrieval and updating of data in a timely manner
Semiometrics: producing a compositional view of influence
No full textHigh-impact academic papers are not necessarily the most cited. For example, Einstein's 'Special Relativity' paper from 1905 received (and continues to receive) fewer citations from other papers than his 'Brownian Motion" paper of the same year, despite the former radically changing the course of an entire scientific discipline to a much greater extent. Similarly, 'impact' metrics using citation count alone are, it is argued, not adequate for determining the scientific influence of papers, authors or small groups of authors. Although valid, they remain controversial when used to determine influence of larger groups or journals. While the term 'impact' has become closely linked to a journal's citation-based Journal Impact Factor score, this thesis uses the term 'influence' to describe the wider effectiveness of research, combining citation and metadata analysis to allow richer calculations to be performed over large-scale document networks. As a result, more qualitative influence ratings can be determined and a broader outlook on scientific disciplines can be produced. These ratings are best applied using an ontology-based data source, allowing more efficient inference than under a traditional RDBMS system, and allowing easier integration between heterogeneous data sources. These metrics, termed 'Semantic Bibliometrics' or 'Semiometrics', can be applied at a variety of levels of granularity, allowing a compositional framework for impact and influence analysis. This thesis describes the process of data preparation, systems architecture, metric value and data integration for such a system, introducing novel approaches at all four stages, thereby creating a working semiometrics system for determining influence at different semantic levels of granularity
1898-1899 field notebook of Spencer A. Beach
No full textHandheld flip note book for field use. Two PDFs -one high res and one OCR. Also included is a photo of S. A. Beach.1898-1899 field notebook of Spencer A. Beach, who was a horticulturist at the New York State Agricultural Experiment Station in Geneva, New York from 1891 to 1905. He was lead author on the monumental book "Apples of New York" which is still regarded with much esteem today. He went on to a position as Chair of Horticulture at Iowa Agricultural College. The notebook contains notes on plant breeding, especially castrating and cross pollinating. Notes include data on apples, grapes, gooseberries, melons, cabbage, turnips, etc

Liriomyza fricki Spencer

All., Oxytropis campestris (L.) DC. var. spicata Hook., Pisum L., Trifolium hybridum L., T. repens L., Vicia americana Muhl., V. villosa Roth (Frick 1959; Spencer 1965, 1969; Lonsdale 2017; Scheffer & Lonsdale 2018). The Oxytropis record was originally reported as O. sericea Nutt. (Lonsdale 2017), but according to USDA, NRCS (2017), O. campestris var. spicata is the only valid taxon occurring in British Columbia that has been referred to as O. sericea. Spencer (1969) also attributed to Liriomyza fricki empty leaf mines on “ Caragana pubescens ” in Alberta, apparently referring to C. arborescens Lam. The erroneous record of Vigna Savi (Sehgal 1971; Lonsdale 2011) can be traced back to Stegmaier’s (1968) listing of Vicia villosa as Vigna villosa. Leaf mine. (Fig. 141) According to Spencer & Steyskal (1986), a “short linear mine, with frass in greenishblack strips.” Sehgal (1971) described the mine as a small blotch with a short linear beginning. The single confirmed example we have seen was whitish and essentially linear, but it widened dramatically and contorted to form a secondary blotch. The dark green frass particles were deposited rather irregularly, loosely arranged into alternating elongate patches unlike the distinct strips seen in other Liriomyza mines. Puparium. Yellow-orange; formed outside the mine. Distribution.

Remembering Elizabeth Spencer
No full textThis tribute was initially featured on the Paris Review blog and is used here with the author’s permission. *** When she died last December at the age of 98, the novelist Elizabeth Spencer was described as “a national treasure.” Author of nine novels, eight story collections, a memoir and a play, she had mastered every mode of literary fiction. Her first novel appeared in 1948 and her most recent book in 2016. On the page, Spencer makes what’s technically difficult seem unusually clear and th..
