Information Retrieval for Multivariate Research Data Repositories
No full textIn this dissertation, I tackle the challenge of information retrieval for multivariate research data by providing novel means of content-based access.Large amounts of multivariate data are produced and collected in different areas of scientific research and industrial applications, including the human or natural sciences, the social or economical sciences and applications like quality control, security and machine monitoring. Archival and re-use of this kind of data has been identified as an important factor in the supply of information to support research and industrial production. Due to increasing efforts in the digital library community, such multivariate data are collected, archived and often made publicly available by specialized research data repositories. A multivariate research data document consists of tabular data with columns (measurement parameters, e.g., temperature, pressure, humidity, etc.) and rows (observations). To render such data-sets accessible, they are annotated with meta-data according to well-defined meta-data standard when being archived. These annotations include time, location, parameters, title, author (and potentially many more) of the document under concern. In particular for multivariate data, each column is annotated with the parameter name and unit of its data (e.g., water depth [m]).The task of retrieving and ranking the documents an information seeker is looking for is an important and difficult challenge. To date, access to this data is primarily provided by means of annotated, textual meta-data as described above. An information seeker can search for documents of interest, by querying for the annotated meta-data. For example, an information seeker can retrieve all documents that were obtained in a specific region or within a certain period of time. Similarly, she can search for data-sets that contain a particular measurement via its parameter name or search for data-sets that were produced by a specific scientist. However, retrieval via textual annotations is limited and does not allow for content-based search, e.g., retrieving data which contains a particular measurement pattern like a linear relationship between water depth and water pressure, or which is similar to example data the information seeker provides.In this thesis, I deal with this challenge and develop novel indexing and retrieval schemes, to extend the established, meta-data based access to multivariate research data. By analyzing and indexing the data patterns occurring in multivariate data, one can support new techniques for content-based retrieval and exploration, well beyond meta-data based query methods. This allows information seekers to query for multivariate data-sets that exhibit patterns similar to an example data-set they provide. Furthermore, information seekers can specify one or more particular patterns they are looking for, to retrieve multivariate data-sets that contain similar patterns. To this end, I also develop visual-interactive techniques to support information seekers in formulating such queries, which inherently are more complex than textual search strings. These techniques include providing an over-view of potentially interesting patterns to search for, that interactively adapt to the user's query as it is being entered. Furthermore, based on the pattern description of each multivariate data document, I introduce a similarity measure for multivariate data. This allows scientists to quickly discover similar (or contradictory) data to their own measurements.EG Graphics Dissertation Onlin
Clavicornaltica Scherer 1974
No full textClavicornaltica Scherer, 1974 Clavicornaltica Scherer, 1974: 58 (type species Clavicornaltica besucheti Scherer 1974: 60, by original designation; type locality Sri Lanka; type depository Natural History Museum, Geneva). Clavicornaltica is easily recognizable from other flea beetle genera, most of all by its clavate antenna (Figs. 1–4), a feature that it shares only with the Caribbean endemic genus Normaltica Konstantinov. The antenna of Clavicornaltica differs from that of Normaltica by the antennomere 4 being the shortest. In Normaltica, antennomere 5 is shorter than 4. Among other diagnostic features are: body small, round and convex in lateral view (Figs. 4–8); head flat in lateral view with wide frontal ridge, lacking supracallinal sulci (Fig. 2); with well developed grooves to receive basal antennomeres (Figs. 2–4); frons very broad; orbit wide (Fig. 2); last 4 antennomeres bearing many long setae, appearing velvety; antennomere 2 as wide (or wider) basally as apically (Fig. 3); eyes ovate, with relatively large, bulging ommatidia; maxillary palpi large, fusiform (Figs. 2, 4); pronotum wider than long, but longest at midline; anterolateral callosity of pronotum extremely long, so that setiferous pore situated well behind middle of lateral margin (Fig. 4); elytra brown, shiny, without calli; scutellum triangular, small, impunctate; metasternum projecting anteriorly between mesocoxae, completely covering mesosternum ventrally (Figs. 9–10); remnants of mesosternum positioned vertically relative to entire beetle body; femora dorsoventrally flat with groove to receive tibiae (Figs. 11–12); all tibiae channeled dorsally; third metatarsomere very narrow, with fourth situated at its base; metatibial spur long; abdominal sternite 1 narrow near middle, adjacent to intercoxal process and much wider laterally near margin, with longitudinal ridge widening anteriorly (Fig. 21); apical abdominal tergum with wide median groove (Figs. 26, 29), having row of setae in middle; male genitalia abruptly curved in lateral view with long basal part (except C. rileyi); female genitalia (Figs. 19 –33) composed of full set of structures including tergite IX (Figs. 20, 22, 24); spermatheca with pump and receptacle forming angle, but not separated from each other by distinct border (Figs. 19, 23, 27); tignum narrow and long, without sclerotization posteriorly (Fig. 24, 31); vaginal palpi (Figs. 20, 24, 28) fused basally (their shape and degree of separation vary from species to species).Published as part of Konstantinov, Alexander S. & Duckett, Catherine N., 2005, New species of Clavicornaltica Scherer (Coleoptera: Chrysomelidae) from continental Asia, pp. 49-64 in Zootaxa 1037 on page 50, DOI: 10.5281/zenodo.16975
