Überblick Aufgaben und Probleme der Sprachtechnologie
Gesprochene Sprache Texttechnologien Ausblick

WAS IST SPRACHTECHNOLOGIE
Eigentlich eine Klasse von Technologien in der Informations- technologie, die Wissen über die Struktur des menschlichen Sprachen verwenden, um die maschinelle Verarbeitung der Sprache zu ermöglichen bzw. zu verbessern. Beispiel: Microsoft Word verarbeitet zwar Sprache, enthält aber im Kern nur sehr wenig Sprachtechnologie. Sprachtechnologie steckt aber in der Erkennung von Satzgrenzen für die Formatierung, in der automatischen Silbentrennung, in der Rechtschreibkontrolle und in der Grammatikkontrolle. Nach Meinung der führenden Experten in der Computerindustrie ist die Sprachtechnologie eine Schlüsseltechnologie für den weiteren Fortschritt in der Computertechnik.

Aber der Computer beherrscht die menschliche Sprache nicht!
Akzeptanz Das Hauptproblem für die Akzeptanz des Computers ist das Sprachproblem Der Standardanwender beherrscht keine Computersprachen. Der Standardanwender mag Computersprachen nicht. Der Standardanwender will auch keine Computersprachen lernen. Die Sprache, die der Mensch bestens beherrscht, ist seine Muttersprache. Das natürlichste Medium für die unmittelbare Übermittlung von Information ist die gesprochene Sprache. Die wichtigste Klasse von Daten sind Texte. Der Standardanwender verwendet die Maschine zur Produktion von Texten in menschlicher Sprache. Computer tun sich schwer in der Verarbeitung und Verwaltung von Texten Aber der Computer beherrscht die menschliche Sprache nicht!

Grenzen der Technologie
Der Computer wird so bald nicht sprechen und schreiben wie wir KEINE SPRACHBEHERRSCHUNG OHNE ALLGEMEINES WISSEN Wörterbücher und Grammatiken können wir formalisieren Bei der Semantik wird es schon schwerer Dialog kann nur recht einfach modelliert werden Begrenztes Domänenwissen ist machbar Beim Allgemeinwissen und großem Fachwissen hört es auf Wir müssen das Problem begrenzen, um zu vernünftigen Anwendungen zu gelangen

Weder Sprachverstehen noch Sprachproduktion sind bisher gelöst.
STAND DER KUNST Weder Sprachverstehen noch Sprachproduktion sind bisher gelöst. Aber: Wir besitzen heute sogenannte flache Verfahren, die zwar kein Verstehen ermöglichen, aber für viele Anwendungen oft völlig ausreichen. flache Ansätze (effizient und robust) statistische Methoden, Mustergrammatiken tiefe Ansätze (präzise und korrekt) linguistische Prinzipien, Constraints oder komplexe Regelwerke

AUFGABEN DES IM Die Aufgabe des Informationsmanagements ist die Verwaltung und Nutzbarmachung von sehr großen Informationsmengen, wie wie sie heute bereits auf dem WWW, in Intranets und in großen Text-Datenbanken finden. Das Netz macht sie erst einmal nur verfügbar. Im Gegensatz zu herkömmlichen Datenbanken ist die Information viel weniger vorstrukturiert (in Sinne der Strukturierung von Computerdaten). Auf der anderen Seiten sind die relevanten inhaltlichen Strukturen natürlich weitaus komplexer. Durch die Digitalisierung von großen Teilen des menschlichen Wissen (z.B. digitale Bibiliotheken, Filmarchive etc.) wird dieses Problem noch zunehmen.

PROBLEME DES INFORMATION MANAGEMENT
Distributivität Die Information liegt auf verschiedenen Maschinen Heterogenität Vielzahl von Dokumentformaten Multilingualität Multimedialität (z.B. Sprache, Bilder, Klänge), Multimodalität (z.B. geschr. u. gesprochene Sprache, Filmdateien o Realzeitübertragungen) Unstrukturiertheit keine einheitliche Klassifikation, keine einheitliche interne Strukturierung. keine einheitliche u. verläßliche Hypertextverknüpfung Redundanz Viele Informationen sind mehrfach vorhanden.

INFORMATION MANAGEMENT
Information wird gewonnen kategorisiert gefiltert zusammengeführt strukturiert dem Benutzer zugeführt adäquat präsentiert

Multilingualität als Herausforderung
Eine große Chance tut sich auf: Es wird möglich sein, durch das niedergeschriebene Wissen der Menschheit zu navigieren, ohne an der Sprachgrenze stehenbleiben zu müssen. Diese technologische Herausforderung erfordert aber Fortschritte auf den folgenden Gebieten: lexikalische Semantik konzeptuelle Strukturierung Verbesserungen in maschineller Übersetzung

Sprache im WWW Sprache ist nur ein Medium auf dem WWW.
Aber unter den verschiedenen Medien hat die Sprache einen besonderen Status. Bücher, Filme, Bilder, Musikstücke und Computerprogramme beschreiben und finden wir am besten mit Sprache. Nur mithilfe der Sprache können wir Wissen strukturieren und sinnvoll vernetzen. Die Sprache ist das Gewebe des World Wide Web

Menschliche Sprache Die Sprache hat Seiten, die dem Menschen leichtfallen, dem Computer hingegen schwer. Insbesondere: Ambiguität: viele Wörter und Phrasen haben mehrere Bedeutungen Paraphrasen: es gibt viele Möglichkeiten, das Gleiche auszudrücken Ungenauigkeit: oft ist die Bedeutung von Ausdrücken unscharf

Maschinelle Übersetzung
Die vollautomatische maschinelle Übersetzung (fully automatic maschine translation – FAMT) beliebiger Texte ist heute nicht möglich. Das liegt nicht an der linguistischen Verarbeitung der Texte, sondern am fehlenden Wissen der Maschine über die Inhalte. Für sehr eingeschränkte Gegenstandsbereiche und Textarten können aber brauchbare Übersetzungen geliefert werden. Ansonsten dient die maschinelle Übersetzung heute erfolgreich als Vorstufe für menschliche Übersetzung (machine-assisted human translation – MAHT).

MÜ ist dennoch brauchbar
Eine zufriedenstellende automatische Übersetzung beliebiger Texte ist heute also nicht möglich. Aber die Technologie liefert Übersetzungen, die den Leser sehr wohl das Thema und die wesentlichsten Inhalte erkennen lassen. Wir arbeiten mit dem Übersetzungssystem LOGOS. Andere große Übersetzungssysteme (SYSTRAN, METAL) werden ebenfalls für WWW Anwendungen eingesetzt. Die Übersetzungen nennen wir indikative Übersetzungen.

THE ONE-CLICK APPROACH
New wireless voice technology introduced Posted at 5:09 PM PT, Feb 8, 1999 By Stephen Lawson, InfoWorld Electric NTT Labs on Monday brought Dick Tracy into the enterprise, introducing a wireless voice and data system that can use a wrist radio at the Demo 99 conference. AirWave technology, demonstrated for the first time in the United States at this week's conference in Indian Wells, Calif., is based on a wireless PBX. Small, handheld phones -- and a wrist radio that looks like an oversized watch -- can be used to make voice calls and exchange data around a building or campus. The handheld phones can be switched to a public cellular mode to become conventional cell phones. Company representatives touted the system as offering higher voice quality than a typical PBX. Airwave is based on NTT's Personal Handyphone System, which is currently deployed by more than 600 users in Japan, according to the company. Modems built in to both devices allow users to plug in a notebook or portable device for dial-up data connections as fast as 64Kbps. Users can exchange files or , or access a LAN or the Internet. There is no airtime charge for AirWave communications in the building or campus. AirWave systems are scheduled to be available through distribution partners by the end of this year, priced as low as $400 per user. NTT Labs, the research and development arm of NTT Corp., in Tokyo, can be reached at

CATEGORIZATION Hypermedia, in computer science, the integration of graphics, sound, video, or any combination into a primarily associative system of information storage and retrieval. Hypermedia, especially in an interactive format where choices are controlled by the user, is structured around the idea of offering a working and learning environment that parallels human thinking˘that is, an environment that allows the user to make associations between topics rather than move sequentially from one to the next, as in an alphabetic list. The term hypertext was coined in 1965 by Ted Nelson to describe documents, as presented by a Computer, that express the no nlinear structure of ideas, as opposed to the linear format of books, film, and speech. The term hypermedia, more recently introduced, is nearly synonymous but emphasizes the nontextual components of hypertext, such as animation, recorded sound, and video. Hypermedia topics are thus linked in a manner that allows the user to jump from subject to related subject in searching for information. For example, a hypermedia presentation on navigation might include links to such topics as astronomy, bird migration, geography, satellites, and radar. If the information is primarily in text form, the product is hypertext; if video, music, animation, or other elements are included, the product is hypermedia. Microsoft (R) Encarta.

Hypermedia, especially in an interactive format where choices are controlled by the user, is structured around the idea of offering a working and learning environment that parallels human thinking˘that is, an environment that allows the user to make associations between topics rather than move sequentially from one to the next, as in an alphabetic list. The term hypertext was coined in 1965 by Ted Nelson to describe documents, as presented by a Computer, that express the nonlinear structure of ideas, as opposed to the linear format of books, film, and speech. The term hypermedia, more recently introduced, is nearly synonymous but emphasizes the nontextual components of hypertext, such as animation, recorded sound, and video. Hypermedia topics are thus linked in a manner that allows the user to jump from subject to related subject in searching for information. For example, a hypermedia presentation on navigation might include links to such topics as astronomy, bird migration, geography, satellites, and radar. If the information is primarily in text form, the product is hypertext; if video, music, animation, or other elements are included, the product is hypermedia. Microsoft (R) Encarta.

Instead, it said it wants to investigate developments in the industry since the trial concluded and evaluate whether additional conduct-related provisions are necessary, especially in the absence of a breakup. In a statement issued Thursday morning, the Justice Department said it had taken these positions in an effort to "streamline the case with the goal of securing an effective remedy as quickly as possible.“ Instead of a breakup, the Justice Department said it will ask that Microsoft have certain restrictions placed on its conduct modeled on those the original trial judge imposed on the company in June 2000 but were postponed pending the appeal. In his original order, Judge Jackson imposed a series of restrictions on Microsoft's business practices which were to be effective as the companymoved to split its business in two. Among the conduct remedies Judge Jackson originally imposed were: prohibiting Microsoft from punishing hardware and software companies working on competing products; prohibiting it from favoring computer companies and software developers that helped Microsoft exclude competitors; makers under uniform prices and terms according to a publicly available schedule; and barring Microsoft from interfering with the way PC makers set up startup screens, this Windows desktop preferences, and Internet connection wizards.
