Scalable Named Entity Identification in Classical Studies

The Perseus Project and the Collections and Archives of Tufts University propose to develop infrastructure for finding references to particular people and places from classical antiquity in several ancient and modern languages in primary and secondary source collections. We will offer and publish open-source, stand alone services and Fedora repository disseminators for searching, browsing, and visualizing entities within the Tufts Digital Library. Under a creative commons license, we will publish knowledge sources such as: linguistic data to identify forms of the most common 60,000 proper classical names in seven languages; knowledge base of the 30,000 people and places most prominent in texts; indices associating c. 200,000 passages with particular entities and an association network of 500,000 tagged names for named entity identification systems; automatically generated index of classical people and places identified in a 1 billion-word testbed of both scholarly and general cultural documents

New methods for working with old languages: Corpus Linguistics and the future of Textual Scholarship

We are seeking DFG/NEH support to allow us to host workshops in the US in the summer of 2009 and in Germany in the summer of 2010 in order to explore the application of emerging analytical technologies to classics in particular and the humanities in general. These workshops will focus not only on emerging services (such as named entity recognition, syntactic and morphological analysis, text mining) and knowledge structures (such as domain-specific ontologies), but on the new forms of scholarly knowledge and intellectual analysis that arise as a result. The 2009 workshop will produce a series of papers that document the state of language technologies in the field of classical philology and propose a roadmap for a more general cyberinfrastructure for the study of historical linguistic sources. These papers will circulate during the 2009-10 academic year and lay the foundation for the 2010 workshop in Germany, which will engage other humanities disciplines

Working with Text in a Digital Age

This Institute will provide 30 participants with three weeks in which (1) to develop hands on experience with TEI-XML, (2) to apply methods from information retrieval, text visualization, and corpus and computational linguistics to the analysis of textual and linguistic sources in the Humanities, and (3) to rethink not only their own research agendas but also new relationships between their work and non-specialists (e.g., an expansion in opportunities for tangible contributions and significant research by undergraduates, new collaborations that transcend boundaries of language and culture, and increased opportunities for the general public both to contribute to our understanding of the past). A two-day conference on the theme of the Institute will then follow in the summer of 2013 with an open call for contributions and will provide both a venue for and a challenge to the issues/ideas raised during the initial Institute and their importance for the digital humanities

The Linked Fragment: TEI and the encoding of text reuses of lost authors

This paper presents a joint project of the Humboldt Chair of Digital Humanities at the University of Leipzig, the Perseus Digital Library at Tufts University, and the Harvard Center for Hellenic Studies to produce a new open series of Greek and Latin fragmentary authors. Such authors are lost and their works are preserved only thanks to quotations and text reuses in later texts. The project is undertaking two tasks: (1) the digitization of paper editions of fragmentary works with links to the source texts from which the fragments have been extracted; (2) the production of born-digital editions of fragmentary works. The ultimate goals are the creation of open, linked, machine-actionable texts for the study and advancement of the field of Classical textual fragmentary heritage and the development of a collaborative environment for crowdsourced annotations. These goals are being achieved by implementing the Perseids Platform and by encoding the Fragmenta Historicorum Graecorum, one of the most important and comprehensive collections of fragmentary authors

A Six-Planet System Around the Star HD 34445

We present a new precision radial velocity dataset that reveals a multi-planet system orbiting the G0V star HD 34445. Our 18-year span consists of 333 precision radial velocity observations, 56 of which were previously published, and 277 which are new data from Keck Observatory, Magellan at Las Campanas Observatory, and the Automated Planet Finder at Lick Observatory. These data indicate the presence of six planet candidates in Keplerian motion about the host star with periods of 1057, 215, 118, 49, 677, and 5700 days, and minimum masses of 0.63, 0.17, 0.1, 0.05, 0.12 and 0.38 Jupiter masses respectively. The HD 34445 planetary system, with its high degree of multiplicity, its long orbital periods, and its induced stellar radial velocity half-amplitudes in the range $2 \,{\rm m\, s^{-1}} \lesssim K \lesssim 5\,{\rm m\, s^{-1}}$ is fundamentally unlike either our own solar system (in which only Jupiter and Saturn induce significant reflex velocities for the Sun), or the Kepler multiple-transiting systems (which tend to have much more compact orbital configurations)Comment: 10 pages, 11 figure

Skeletal muscle AMPK is essential for the maintenance of FNDC5 expression

Fibronectin type III domain‐containing protein 5 (FNDC5) expression is controlled by the transcriptional co‐activator, peroxisome proliferator‐activated receptor gamma, coactivator 1 alpha (PGC1α). FNDC5 expression has been shown to be increased in muscle in response to endurance exercise in some but not all studies, therefore a greater understanding of the mechanisms controlling this process are needed. The AMP‐activated protein kinase (AMPK) is activated by exercise in an intensity dependent manner and is an important regulator of PGC1α activity; therefore, we explored the role of AMPK in the regulation of FNDC5 using AMPK β1β2 double muscle‐null mice (AMPK DMKO), which lack skeletal muscle AMPK activity. We found that FNDC5 expression is dramatically reduced in resting muscles of AMPK DMKO mice compared to wild‐type littermates. In wild‐type mice, activating phosphorylation of AMPK was elevated immediately post contraction and was abolished in muscle from AMPK DMKO mice. In contrast, PGC1α was increased in both wild‐type and AMPK DMKO mice 3 h post contraction but FNDC5 protein expression was not altered. Lastly, acute or chronic activation of AMPK with the pharmacological AMPK activator AICAR did not increase PGC1α or FNDC5 expression in muscle. These data indicate that skeletal muscle AMPK is required for the maintenance of basal FNDC5 expression

Open Philology at the University of Leipzig

The Open Philology Project at the University of Leipzig aspires to re-assert the value of philology in its broadest sense. Philology signifies the widest possible use of the linguistic record to enable a deep understanding of the complete lived experience of humanity. Pragmatically, we focus on Greek and Latin because (1) substantial collections and services are already available within these languages, (2) substantial user communities exist (c. 35,000 unique users a month at the Perseus Digital Library), and (3) a European-based project is better positioned to process extensive cultural heritage materials in these languages rather than in Chinese or Sanskrit. The Open Philology Project has been designed with the hope that it can contribute to any historical language that survives within the human record. It includes three tasks: (1) the creation of an open, extensible, repurposable collection of machine-readable linguistic sources; (2) the development of dynamic textbooks that use annotated corpora to customize the vocabulary and grammar of texts that learners want to read, and at the same time engage students in collaboratively producing new annotated data; (3) the establishment of new workflows for, and forms of, publication, from individual annotations with argumentation to traditional publications with integrated machine-actionable data
