title: An open-source toolkit for mining Wikipedia

authors: Milne, David N.

subjects: Annotation

abstract: The online encyclopedia Wikipedia is a vast, constantly evolving tapestry of interlinked articles. For developers and researchers it represents a giant multilingual database of concepts and semantic relations, a potential resource for natural language processing and many other research areas. This paper introduces the Wikipedia Miner toolkit, an open-source software system that allows researchers and developers to integrate Wikipedia's rich semantics into their own applications. The toolkit creates databases that contain summarized versions of Wikipedia's content and structure, and includes a Java API to provide access to them. Wikipedia's articles, categories and redirects are represented as classes, and can be efficiently searched, browsed, and iterated over. Advanced features include parallelized processing of Wikipedia dumps, machine-learned semantic relatedness measures and annotation features, and XML-based web services. Wikipedia Miner is intended to be a platform for sharing data mining techniques. Annotation; Disambiguation; Ontology extraction; Semantic relatedness; Toolkit; Wikipedia

title: Platinum(II), palladium(II), nickel(II), and gold(I) complexes of the “electrospray-friendly” thiolate ligands 4-SC₅H₄N- and 4-SC₆H₄OMe-

authors: Decker, Corry

subjects: thiolate ligands

abstract: The series of platinum(II), palladium(II), and nickel(II) complexes [ML₂(dppe)] [M = Ni, Pd, Pt; L = 4-SC₅H₄N or 4-SC₆H₄OMe; dppe = Ph₂PCH₂CH₂PPh₂] containing pyridine-4-thiolate or 4-methoxybenzenethiolate ligands, together with the corresponding gold(I) complexes [AuL(PPh3)], were prepared and their electrospray ionization mass spectrometric behavior compared with that of the thiophenolate complexes [M(SPh)₂(dppe)] (M = Ni, Pd, Pt) and [Au(SPh)(PPh₃)]. While the pyridine-4-thiolate complexes yielded protonated ions of the type [M + H]+ and [M + 2H]²+ ions in the Ni, Pd, and Pt complexes, an [M + H]+ ion was only observed for the platinum derivative of 4-methoxybenzenethiolate. Other ions, which dominated the spectra of the thiophenolate complexes, were formed by thiolate loss and aggregate formation. The X-ray crystal structure of [Pt(SC₆H₄OMe-4)₂(dppe)] is also reported.

title: COVID-19 and blind spaces: Responding to digital (in)accessibility and social isolation during lockdown for blind, deafblind, low vision, and vision impaired persons in Aotearoa New Zealand

authors: Graham, Rebekah Sarah

abstract: In this chapter we, as Indigenous (Māori) and non-Indigenous (Pākehā) academics, practitioners, and disability advocates critically examine the experiences of people who are blind, deafblind, low vision and vision impaired (BLV) during the COVID-19 lockdown of Aotearoa New Zealand. We pay particular attention to the ways in which access (or lack thereof) to digital spaces facilitated experiences of social inclusion (and exclusion). Digital connectivity was heavily relied upon during lockdown in Aotearoa New Zealand to disseminate health information and to connect people socially. The use of digital technologies during lockdown extended the interpersonal space of the home beyond the physicality of the urban home people were confined to, drawing people together across the country and creating a sense of shared experience. However, these experiences were not shared equally across the citizenry. Conversations during lockdown with disability advocates and practitioners working with BLV persons identified that. For example, the government website on COVID19 was initially inaccessible for BLV persons and there were assumptions of digital accessibility and literacy within the domestic space of the home. Taken together, these exacerbated existing inequities for BLV persons, some of whom experience multiple domains of exclusion (for example, Indigenous BLV persons with reduced access to services and for whom English is their second language). Drawing on Lefebvre’s (1991) work on the dialectics of space and Lewin’s (1936/2013) construction of the life-space, we consider the interplay of space and experience with regards to the digital and physical space(s) available and inhabited during the shared social experience of lockdown. We discuss possibilities for co-creating socially inclusive (digital) spaces of belonging that reflect and refract life-space relational connections across social groups. Our reflections on the lockdown experience include opportunities post-pandemic for policy makers and practitioners to address digital accessibility inequities.
