Many vendors offer content management, knowledge management, or data management systems that large collection of data without a taxonomy they describe as complete solutions. Most of these solutions is like driving in unknown territory without involve taking data that sits in various inaccessible locations the benefit of a map or road signs: You may or formats, such as paper, microfiche or legacy electronic iterations, and converting it into a number of different outputs, eventually stumble upon your destination, from XML to HTML to PDF. However, government agencies, but chances are you’ll encounter a lot of with their vast realms of mission-critical data, require more dead ends and detours first. than simply having data converted to a common format. They need a road map. —Penny Grossman, “Search in Focus: Implementing a Taxonomy,” July 2007 The real value to the enterprise is in the tagging and structuring of data into meaningful classification schemes, making content not just searchable but also linkable to other relevant content. An indexing taxonomy provides significant benefits to an Beyond Search enterprise that manages a large body of information: In 2004, the International Data Corporation reported that • By controlling synonyms and interpreting ambiguous knowledge workers spend 15% to 30% of their workday expressions, an index provides a reliable guide to an searching for information, and 50% of their online searches are agency’s data.

As Penny Grossman points out in her essay, Long recognized as a pioneer in online search technology, “Search engines don’t know the difference between LexisNexis knows that search alone is no longer enough reading glasses and drinking glasses, but a taxonomy to meet the information management needs of today’s puts your query in context.” government workers, who daily encounter a variety of • An index separates wheat from chaff, ignores incidental data format, integration and access problems.

In a July 11, 2007, Gartner Industry Report entitled “Hype Cycle for Government Transformation, 2007,” contributors Richard Harris and Mark Gilbert describe indexing as a natural and desirable enhancement of search technology: 2

Transforming Content via Enterprise information access technologies an Enterprise Taxonomy are entering a new phase of deployment While your agency may already use a content management and use. Technologies are maturing and system, it is probably not delivering the kind of relevant, now offer better indexing, querying, ranked, and meaningful answer sets that your users require. Consider court operating systems in the areas of Case presentation and drill-down of results. Management, Legal Research, and Dockets and Record However, the real value of information Retrieval. Information within these systems is structured, access technologies is in the upfront connected, transferable, and actionable. But related information in court archives (e.g., opinions, transcripts, and ongoing efforts needed to establish briefs, legislative histories) may reside on paper, microfiche, effective taxonomies, to index, and to or in legacy digital formats—unstructured, isolated, and classify content of all kinds that must be static—and thus, not easily accessible or transferable. accessed. By itself, the search function Digital Asset Management makes archived content as has limited value. The classification and accessible as new content, with a consistent scheme across modeling (that is, the taxonomy, ontology repositories. The first step in the process is to covert your and vocabularies) of the content that is to be content—paper, microfiche, structured or unstructured electronic content—to a consistent format and layout. The searched must be properly established and process includes capturing images of the pieces of data that managed in an ongoing fashion to provide make up the content; cleaning up and enhancing the images meaningful results. (i.e., cropping, adding contrast, sharpening edges, converting colors, centering text); scanning and applying optical character recognition (OCR) technology to the images; and then using XML to tag the images with metadata—information about the These are precisely the types of opportunities presented by the data that categorizes the words or passages of text as a specific LexisNexis® Digital Asset Management Solution Suite, which data type (e.g., publication date, byline, subject terms). offers an enterprise-wide approach encompassing the capture, transformation, storage, preservation and delivery of mission- The real value, however, comes during the transformation critical information. stage, the second stage in the process, when LexisNexis implements taxonomy and linking processes and technologies, The LexisNexis end-to-end Digital Asset Management which provide a systematic way of classifying knowledge— offerings demonstrate how Government agencies can achieve usually via a hierarchical structure—and relating that a variety of positive outcomes—including improving access to knowledge to other relevant information. This “Enterprise agency intellectual property. Taxonomy” is accomplished by a combination of human expertise and algorithmic programming. Using a rule-based classification system developed by computational linguists, LexisNexis indexers build and maintain concept definitions. This creates rules behind each index term instructing a global indexing application programming interface (GIAPI) on how to identify relevant documents during a search. The GIAPI then “tags” documents matching or exceeding a defined threshold. 3
