The languages currently covered are Czech, Finnish, French, German, Irish, Italian, Norwegian, Polish, Slovak, Swedish and, more recently, Chinese, as well as English, which is considered to be the pivot language. The goal of the project is to provide much-needed data for contrastive corpus-based linguistics. The ICC corpus is committed to the idea of re-using existing multilingual resources as much as possible and the design is modelled, with various adjustments, on the International Corpus of English (ICE). As such, ICC will contain approximately the same balance of forty percent of written language and 60 percent of spoken language distributed across 27 different text types and contexts. A number of issues encountered by the project teams are discussed, ranging from copyright and data sustainability to technical advances in data distribution.},

These contradictions can arise from basing global conclusions on restricted methodologies-such as assigning undue weight to individual linguistic features, or to choice of particular text samples and text types. The present study uses a 'multi-feature/multi-dimension' approach, which includes a broad range of linguistic features and text types in a single quantitative analysis, to provide a global description of similarities and differences among spoken/written text types in English. The distribution of 41 linguistic features in 545 text samples of approximately 2000 words each is subjected to factor analysis (a multivariate statistical technique). Three underlying textual dimensions are identified: Interactive vs. Edited Text, Abstract vs. Situated Content, and Reported vs. Immediate Style. To demonstrate the value of the multi-feature/multi-dimension approach, the specific findings of earlier studies are reconciled within the model proposed here.]},

The aim of this project is to develop an innovative corpus analysis platform to tackle the increasing demands of modern linguistic research. The platform will facilitate new linguistic findings by making it possible to manage and analyse primary data and annotations in the petabyte range, while at the same time allowing an undistorted view of the primary linguistic data, and thus fully satisfying the demands of a scientific tool. An additional important aim of the project is to make corpus data as openly accessible as possible in light of unavoidable legal restrictions, for instance through support for distributed virtual corpora, user-defined annotations and adaptable user interfaces, as well as interfaces and sandboxes for user-supplied analysis applications. We discuss our motivation for undertaking this endeavour and the challenges that face it. Next, we outline our software implementation plan and describe development to-date.},
