Colletes ravulus NOSKIEWICZ 1936
No full textColletes ravulus NOSKIEWICZ 1936 Colletes ravulus NOSKIEWICZ 1936 - NOSKIEWICZ 1936: 335-337. The specimens assigned to C. edentulus in KUHLMANN (2009) all belong to C. ravulus as understood here. Description of female: Colletes ravulus and C. tuberculatus differ only in the sculpture of the clypeus and in the punctation of the terga. In C. ravulus, the distance between the punctures of the clypeus is slightly broader (Fig. 3) than in C. tuberculatus (Fig. 1), but the sculpture is otherwise identical. In C. ravulus, the punctation on the disc of T1 is much denser and the punctures are slightly smaller (Fig. 6) than in C. tuberculatus (Fig. 4). In both species the punctation becomes much smaller and denser apically, but more so in C. ravulus (Fig. 6).Published as part of Kuhlmann, M., 2010, Taxonomic notes on some Palaearctic Colletes bees (Insecta: Hymenoptera: Colletidae), pp. 749-755 in Linzer biologische Beiträge 42 (1) on page 751, DOI: 10.5281/zenodo.533300
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Efficient Parsing of Well-Nested Linear Context-Free Rewriting Systems
No full textThe use of well-nested linear context-free rewriting systems has been empirically motivated for modeling of the syntax of languages with discontinuous constituents or relatively free word order. We present a chart-based parsing algorithm that asymptotically improves the known running time upper bound for this class of rewriting systems. Our result is obtained through a linear space construction of a binary normal form for the grammar at hand
Dynamic Programming Algorithms for Transition-Based Dependency Parsers
No full textWe develop a general dynamic programming technique for the tabulation of transition-based dependency parsers, and apply it to obtain novel, polynomial-time algorithms for parsing with the arc-standard and arc-eager models. We also show how to reverse our technique to obtain new transition-based dependency parsers from existing tabular methods. Additionally, we provide a detailed discussion of the conditions under which the feature models commonly used in transition-based parsing can be integrated into our algorithms
