Building a Document Genre Corpus: a Profile of the KRYS I Corpus

This paper describes the KRYS I corpus (http://www.krys-corpus.eu/Info.html), consisting of documents classified into 70 genre classes. It has been constructed as part of an effort to automate document genre classification as distinct from topic detection. Previously there has been very little work on building corpora of texts which have been classified using a non-topical genre palette. The reason for this is partly due to the fact that genre as a concept, is rooted in philosophy, rhetoric and literature, and highly complex and domain dependent in its interpretation ([11]). The usefulness of genre in everyday information search is only now starting to be recognised and there is no genre classification schema that has been consolidated to have applicable value in this direction. By presenting here our experiences in constructing the KRYS I corpus, we hope to shed light on the information gathering and seeking behaviour and the role of genre in these activities, as well as a way forward for creating a better corpus for testing automated genre classification tasks and the application of these tasks to other domains

Anosmin-1 over-expression increases adult neurogenesis in the subventricular zone and neuroblast migration to the olfactory bulb

New subventricular zone (SVZ)-derived neuroblasts that migrate via the rostral migratory stream are continuously added to the olfactory bulb (OB) of the adult rodent brain. Anosmin-1 (A1) is an extracellular matrix protein that binds to FGF receptor 1 (FGFR1) to exert its biological effects. When mutated as in Kallmann syndrome patients, A1 is associated with severe OB morphogenesis defects leading to anosmia and hypogonadotropic hypogonadism. Here, we show that A1 over-expression in adult mice strongly increases proliferation in the SVZ, mainly with symmetrical divisions, and produces substantial morphological changes in the normal SVZ architecture, where we also report the presence of FGFR1 in almost all SVZ cells. Interestingly, for the first time we show FGFR1 expression in the basal body of primary cilia in neural progenitor cells. Additionally, we have found that A1 over-expression also enhances neuroblast motility, mainly through FGFR1 activity. Together, these changes lead to a selective increase in several GABAergic interneuron populations in different OB layers. These specific alterations in the OB would be sufficient to disrupt the normal processing of sensory information and consequently alter olfactory memory. In summary, this work shows that FGFR1-mediated A1 activity plays a crucial role in the continuous remodelling of the adult OB.This research was supported by grants from the Spanish Ministerio de Economía, Innovación y Competitividad MINECO (SAF2009-07842, ADE10-0010, RD07-0060-2007, RD12-0032-12 and SAF2012-40023 to FdC; and BFU2010-18284 to JMG-V), FISCAM (Gobierno de Castilla-La Mancha, Spain—Grant Number PI2007-66), the Junta de Castilla y León (Spain, to EW), and from the Fundación Eugenio Rodríguez Pascual (Spain) to FdC.

KRYS I Corpus

The KRYS I corpus is a collection of over 6300 documents labelled with their genre classes. It was constructed as part of a research initiative to automate document genre classification driven by the Digital Curation Centre. It was carried out at the Humanities Advanced Technology and Information Institute (HATII), University of Glasgow between 2005 and 2008. The notion of genre is deeply embedded in the way humans organise information. Identifying the genre of a document helps to characterise the physical and conceptual structure of the text, helping to capture the style and location of further information within the text. There have been very few genre-labelled corpora available to the research community. Our corpus is made available here to fill this gap and serve as a valuable resource for researchers in: metadata extraction, digital curation, text classification, text mining, computational linguistics, and, pattern recognition
