Functional genre in Illinois State Government digital documents

Provisions for collecting or archiving digital documents can be informed by knowledge of the genres of documents likely to be encountered. Although different aspects of collecting and curation may classify documents into genres based on differing criteria (e.g., size, file format, subject), this document addresses classification based on the functional role the document plays in state government, akin to (Toms, 2001), but here specifically Illinois State Government (ISG). The classifications listed herein are based on an overview of ISG digital documents, encountered in over nine years of gathering and archiving work with and for the Illinois State Library (ISL), and on discussions with practitioners in cataloging and in government documents librarianship. This report states definitions, and including examples of each such genre. State government documents are interesting in this regard in that they are presumably somewhat comparable to both federal government documents and business documents. Perhaps surprisingly, there are also portions of the State Web that are somewhat less than businesslike, either in tone or in technological proficiency of implementation. In this respect state government digital documents may also be useful approximations to documents produced either personally or by small activities. Having a list of government document genres can inform work in information promulgation (e.g., through website design, or the design of a series of printed materials), and the grouping of documents for digital library or archival purposes.Library of Congress / NDIIPP-2 A6075unpublishednot peer reviewe

FISA Reform

Congress and the Executive Branch are poised to take up the issue of FISA reform in 2014. What has been missing from the discussion is a comprehensive view of ways in which reform could be given effect—i.e., a taxonomy of potential options. This article seeks to fill the gap. The aim is to deepen the conversation about abeyant approaches to foreign intelligence gathering, to allow fuller discussion of what a comprehensive package could contain, and to place initiatives that are currently under consideration within a broader, over-arching framework. The article begins by considering the legal underpinnings and challenges to the President\u27s Surveillance Program. It then examines how technology has altered the types of information available, as well as methods of transmission and storage. The article builds on this to develop a taxonomy for how a statutory approach to foreign intelligence gathering could be given force. It divides foreign intelligence gathering into two categories: front-end collection and back-end analysis and use. Each category contains a counterpoise structured to ensure the appropriate exercise of Congressionally-mandated authorities. For the front-end, this means balancing the manner of collection with requirements for approval. For the back-end, this means offsetting implementation with transparency and oversight. The article then considers the constituent parts of each category

Do Multi-Sense Embeddings Improve Natural Language Understanding?

Learning a distinct representation for each sense of an ambiguous word could lead to more powerful and fine-grained models of vector-space representations. Yet while `multi-sense' methods have been proposed and tested on artificial word-similarity tasks, we don't know if they improve real natural language understanding tasks. In this paper we introduce a multi-sense embedding model based on Chinese Restaurant Processes that achieves state of the art performance on matching human word similarity judgments, and propose a pipelined architecture for incorporating multi-sense embeddings into language understanding. We then test the performance of our model on part-of-speech tagging, named entity recognition, sentiment analysis, semantic relation identification and semantic relatedness, controlling for embedding dimensionality. We find that multi-sense embeddings do improve performance on some tasks (part-of-speech tagging, semantic relation identification, semantic relatedness) but not on others (named entity recognition, various forms of sentiment analysis). We discuss how these differences may be caused by the different role of word sense information in each of the tasks. The results highlight the importance of testing embedding models in real applications

This paper presents a comprehensive mathematical framework for depletion rate analysis and ties it to the physics of depletion. Theory was compared with empirical data from 1036 fields and a number of regions. Strong agreement between theory and practice was found, indicating that the framework is plausible. Both single fields and entire regions exhibit similar depletion rate patterns, showing the generality of the approach. The maximum depletion rates for fields were found to be well described by a Weibull distribution. Depletion rates were also found to strongly correlate with decline rates. In particular, the depletion rate at peak was shown to be useful for predicting the future decline rate. Studies of regions indicate that a depletion rate of remaining recoverable resources in the range of 2–3% is consistent with historical experience. This agrees well with earlier “peak oil” forecasts and indicates that they rest on a solid scientific ground.

Private Equity Investment in the BRICs

This Article investigates the legal and economic environment for private equity investments in Brazil, Russia, India and China (“BRIC”). In contrast with disappointing returns in the 1990s, private equity investment has soared in developing countries over the past decade. To explain what has led to the recent success of private equity in the BRICs, this Article will first give an overview of the challenges faced generally when investing in portfolio companies in developing markets and then analyze the legal and economic framework for each of the four BRICs. This Article finds that Brazil and China offer the best opportunities for private equity because investors can rely on strong domestic capital markets for the exit. While India is not far behind, Russia still has room for improvement, particularly with regard to the reliability of its legal system and the attractiveness of its capital markets

Econometrics meets sentiment : an overview of methodology and applications

The advent of massive amounts of textual, audio, and visual data has spurred the development of econometric methodology to transform qualitative sentiment data into quantitative sentiment variables, and to use those variables in an econometric analysis of the relationships between sentiment and other variables. We survey this emerging research field and refer to it as sentometrics, which is a portmanteau of sentiment and econometrics. We provide a synthesis of the relevant methodological approaches, illustrate with empirical results, and discuss useful software
