Abstract

A discourse analysis of the cognitive viewpoint in library and information science (LIS) identifies seven discursive strategies which constitute information as a commodity, and persons as surveyable information consumers, within market economy conditions. These strategies are (a) universality of theory, (b) referentiality and reification of 'images', (c) internationalization of representation, (d) insistence upon knowledge, (e) constitution of the information scientists as an expert in image negotiation, (f) radical individualism and erasure of the social dimension of theory, and (g) instrumental reasons, rules by efficiency, standardization, predictibility,a nd determination of effects. The discourse is guided troughout by a yearning for natural-scientific theory. The effect of the cognitiv viewpoint's discoursive strategy is to anable knowledge acquisition of information processes only when users' and generators 'images' are constituted as objectively given natural scientif entites, and to disable knowledge of the same processes when considered as products of social practices. By its constitution of users as free creators of images, of the information scientist as an expert in image interpretation and delivery, and of databases as repositories of unmediated models of the world, the cognitive viewpoint performs ideological labour for modern capitalist image markets

Abstract

In distinction to current Theory of Communication which treats amount of information as a measure of the statistical rarity of a message, a Theory of Semantic Information is outlined, in which the concept of information carried by a sentence within a given language system is treated as synonymous with the content of this sentence, normalized in a certain way, and the concept of amount of semantic information is explicated by various measures of this content, all based on logical probability functions ranging over the contents. Absolute and relative measures are distinguished, so are D-functions suitable for contexts where deductive reasoning alone is relevant and I-functions suitable for contexts where inductive reasoning is adequate. Of the two major types of amount of information investigated, the one, cont, is additive with respect to sentences whose contents are exclusive, the other, inf, with respect to sentences which are inductively independent. The latter turns out to be formally analogous to the customary information measure function. Various estimate functions of amount of information are investigated leading to generalized semantic correlates of concepts and theorems of current Communication Theory. A concept of semantic noise is tentatively defined, so are efficiency and redundancy of the conceptual framework of a language system. It is suggested that semantic information is a concept more readily applicable to psychological and other investigations than its communicational counterpart.

Abstract

Bruner war der erste Erforscher des Spracherwerbs von Kindern, der Wittgensteins Problem zu würdigen wußte und eine Antwort darauf vorschlug. Wittgensteins allgemeinem Ansatz folgend, behauptete Bruner, daß das Kind den konventionellen Gebrauch eines sprachlichen Symbols dadurch erwirbt, daß es lernt, an einer Interaktionsform (Lebensform, Szene gemeinsamer Aufmerksamkeit) teilzunehmen, die es zunächst nichtsprachlich versteht, so daß die Sprache des Erwachsenen in geteilten Erfahrungen verankert werden kann, deren soziale Bedeutung es schon begreift. Eine Schlüsselkomponente dieses Prozesses ist zunächst ein Kind, das Erwachsene als intentionale Wesen auffassen kann, so daß es in bestimmten Kontexten seine Aufmerksamkeit mit ihnen teilen kann. Eine andere Komponente ist jedoch die bereits existierende, äußere soziale Welt, in der das Kind lebt. Um Sprache zu erwerben, muß das Kind in einer Welt leben, die strukturierte soziale Tätigkeiten aufweist, die es verstehen kann, so wie unser hypothetischer Besucher Ungarns das Kaufen von Fahrkarten und das Reisen mit Zügen verstand. Für Kinder bedeutet das häufig die Wiederkehr derselben routinemäßigen, allgemeinen Aktivität, so daß sie erkennen können, wie diese Aktivität aufgebaut ist und wie die verschiedenen sozialen Rollen in ihr funktionieren. Wenn wir am Spracherwerb interessiert sind, muß der Erwachsene außerdem ein neues sprachliches Symbol auf eine solche Weise verwenden, die das Kind als relevant für die gemeinsame Tätigkeit erkennen kann (nämlich im Gegensatz zur unvermittelten Ansprache des Ungarn auf dem Bahnhof). Wenn ein Kind in eine Welt geboren werden würde, in der dieselbe Art von Ereignis nie wiederkehrte, derselbe Gegenstand nie zweimal erschiene und Erwachsene nie dieselben Ausdrücke im selben Kontext verwendeten, dann würde im allgemeinen schwer zu sehen sein, wie dieses Kind eine natürliche Sprache erwerben könnte, welche kognitiven Fähigkeiten es auch immer haben möge. Eine Reihe von Untersuchungen hat gezeigt, daß Kinder nach ersten Fortschritten beim Spracherwerb neue Wörter am besten in Szenen gemeinsamer Aufmerksamkeit lernen. Oft handelt es sich dabei um solche, die in ihrer täglichen Erfahrung wiederkehren, wie Baden, Füttern, Windelwechseln, Vorlesen und Autofahren. Diese Tätigkeiten sind in vielen Hinsichten analog zu dem Szenario des Fahrkartenkaufs auf einem Bahnhof, insofern das Kind seine eigenen und die Ziele des Erwachsenen in der jeweiligen Situation versteht, was ihm ermöglicht, die Relevanz des Sprachverhaltens des Erwachsenen für diese Ziele zu erschließen. So stellten Tomasello und Todd fest, daß Kinder, die mit ihren Müttern längere Zeit bei Tätigkeiten gemeinsamer Aufmerksamkeit im Alter zwischen zwölf und achtzehn Monaten verbrachten, mit achtzehn Monaten ein größeres Vokabular hatten. Bei der Sprachverwendung Erwachsener innerhalb dieser Szenen gemeinsamer Aufmerksamkeit fanden Tomasello und Farrar sowohl korrelative als auch experimentelle Belege für die Hypothese, daß Mütter, die Sprache beim Versuch verwendeten, der Aufmerksamkeit ihrer Kinder zu folgen (d. h. über einen Gegenstand zu sprechen, der schon im Brennpunkt des Interesses und der Aufmerksamkeit des Kindes stand), Kinder mit einem größeren Vokabular hatten als Mütter, die Sprache beim Versuch verwendeten, die Aufmerksamkeit des Kindes auf etwas Neues zu lenken.

Abstract

Consider a sentence such as "the current price of tea in China is 35 cents per pound." In a library with millions of books we might find many statements of the above form that we could capture today with relatively simple rules: rather than pursuing every variation of a statement, programs can wait, like predators at a water hole, for their informational prey to reappear in a standard linguistic pattern. We can make inferences from sentences such as "NAME1 born at NAME2 in DATE" that NAME more likely than not represents a person and NAME a place and then convert the statement into a proposition about a person born at a given place and time. The changing price of tea in China, pedestrian birth and death dates, or other basic statements may not be truth and beauty in the Phaedrus, but a digital library that could plot the prices of various commodities in different markets over time, plot the various lifetimes of individuals, or extract and classify many events would be very useful. Services such as the Syllabus Finder1 and H-Bot2 (which Dan Cohen describes elsewhere in this issue of D-Lib) represent examples of information extraction already in use. H-Bot, in particular, builds on our evolving ability to extract information from very large corpora such as the billions of web pages available through the Google API. Aside from identifying higher order statements, however, users also want to search and browse named entities: they want to read about "C. P. E. Bach" rather than his father "Johann Sebastian" or about "Cambridge, Maryland", without hearing about "Cambridge, Massachusetts", Cambridge in the UK or any of the other Cambridges scattered around the world. Named entity identification is a well-established area with an ongoing literature. The Natural Language Processing Research Group at the University of Sheffield has developed its open source Generalized Architecture for Text Engineering (GATE) for years, while IBM's Unstructured Information Analysis and Search (UIMA) is "available as open source software to provide a common foundation for industry and academia." Powerful tools are thus freely available and more demanding users can draw upon published literature to develop their own systems. Major search engines such as Google and Yahoo also integrate increasingly sophisticated tools to categorize and identify places. The software resources are rich and expanding. The reference works on which these systems depend, however, are ill-suited for historical analysis. First, simple gazetteers and similar authority lists quickly grow too big for useful information extraction. They provide us with potential entities against which to match textual references, but existing electronic reference works assume that human readers can use their knowledge of geography and of the immediate context to pick the right Boston from the Bostons in the Getty Thesaurus of Geographic Names (TGN), but, with the crucial exception of geographic location, the TGN records do not provide any machine readable clues: we cannot tell which Bostons are large or small. If we are analyzing a document published in 1818, we cannot filter out those places that did not yet exist or that had different names: "Jefferson Davis" is not the name of a parish in Louisiana (tgn,2000880) or a county in Mississippi (tgn,2001118) until after the Civil War.
