- Abstract
- Die Möglichkeiten, die der heutigen Informations- und Wissensgesellschaft für die Beschaffung und den Austausch von Information zur Verfügung stehen, haben kurioserweise gleichzeitig ein immer akuter werdendes, neues Problem geschaffen: Es wird für jeden Einzelnen immer schwieriger, aus der gewaltigen Fülle der angebotenen Informationen die tatsächlich relevanten zu selektieren. Diese Arbeit untersucht die Möglichkeit, mit Hilfe von natürlichsprachlichen Schnittstellen den Zugang des Informationssuchenden zu Volltextdatenbanken zu verbessern. Dabei werden zunächst die wissenschaftlichen Fragestellungen ausführlich behandelt. Anschließend beschreibt der Autor verschiedene Lösungsansätze und stellt anhand einer natürlichsprachlichen Schnittstelle für den Brockhaus Multimedial 2004 deren erfolgreiche Implementierung vor

- Abstract
- The information available in languages other than English in the World Wide Web is increasing significantly. According to a report from Computer Economics in 1999, 54% of Internet users are English speakers ("English Will Dominate Web for Only Three More Years," Computer Economics, July 9, 1999, http://www.computereconomics. com/new4/pr/pr990610.html). However, it is predicted that there will be only 60% increase in Internet users among English speakers verses a 150% growth among nonEnglish speakers for the next five years. By 2005, 57% of Internet users will be non-English speakers. A report by CNN.com in 2000 showed that the number of Internet users in China had been increased from 8.9 million to 16.9 million from January to June in 2000 ("Report: China Internet users double to 17 million," CNN.com, July, 2000, http://cnn.org/2000/TECH/computing/07/27/ china.internet.reut/index.html). According to Nielsen/ NetRatings, there was a dramatic leap from 22.5 millions to 56.6 millions Internet users from 2001 to 2002. China had become the second largest global at-home Internet population in 2002 (US's Internet population was 166 millions) (Robyn Greenspan, "China Pulls Ahead of Japan," Internet.com, April 22, 2002, http://cyberatias.internet.com/big-picture/geographics/article/0,,5911_1013841,00. html). All of the evidences reveal the importance of crosslingual research to satisfy the needs in the near future. Digital library research has been focusing in structural and semantic interoperability in the past. Searching and retrieving objects across variations in protocols, formats and disciplines are widely explored (Schatz, B., & Chen, H. (1999). Digital libraries: technological advances and social impacts. IEEE Computer, Special Issue an Digital Libraries, February, 32(2), 45-50.; Chen, H., Yen, J., & Yang, C.C. (1999). International activities: development of Asian digital libraries. IEEE Computer, Special Issue an Digital Libraries, 32(2), 48-49.). However, research in crossing language boundaries, especially across European languages and Oriental languages, is still in the initial stage. In this proposal, we put our focus an cross-lingual semantic interoperability by developing automatic generation of a cross-lingual thesaurus based an English/Chinese parallel corpus. When the searchers encounter retrieval problems, Professional librarians usually consult the thesaurus to identify other relevant vocabularies. In the problem of searching across language boundaries, a cross-lingual thesaurus, which is generated by co-occurrence analysis and Hopfield network, can be used to generate additional semantically relevant terms that cannot be obtained from dictionary. In particular, the automatically generated cross-lingual thesaurus is able to capture the unknown words that do not exist in a dictionary, such as names of persons, organizations, and events. Due to Hong Kong's unique history background, both English and Chinese are used as official languages in all legal documents. Therefore, English/Chinese cross-lingual information retrieval is critical for applications in courts and the government. In this paper, we develop an automatic thesaurus by the Hopfield network based an a parallel corpus collected from the Web site of the Department of Justice of the Hong Kong Special Administrative Region (HKSAR) Government. Experiments are conducted to measure the precision and recall of the automatic generated English/Chinese thesaurus. The result Shows that such thesaurus is a promising tool to retrieve relevant terms, especially in the language that is not the same as the input term. The direct translation of the input term can also be retrieved in most of the cases.

- Um Firmen und Agenturen die Beobachtungen von Medien zu erleichtern, entwickeln Forscher an der Duisburger Hochschule zurzeit ein System zur automatischen Themenerkennung in Rundfunk und Fernsehen. Das so genannte Alert-System soll dem Nutzer helfen, die für ihn relevanten Sprachinformationen aus Nachrichtensendungen herauszufiltem und weiterzuverarbeiten. Durch die automatische Analyse durch den Computer können mehrere Programme rund um die Uhr beobachtet werden. Noch erfolgt die Informationsgewinnung aus TV- und Radiosendungen auf klassischem Wege: Ein Mensch sieht, hört, liest und wertet aus. Das ist enorm zeitaufwendig und für eine Firma, die beispielsweise die Konkurrenz beobachten oder ihre Medienpräsenz dokumentieren lassen möchte, auch sehr teuer. Diese Arbeit ließe sich mit einem Spracherkenner automatisieren, sagten sich die Duisburger Forscher. Sie arbeiten nun zusammen mit Partnern aus Deutschland, Frankreich und Portugal in einem europaweiten Projekt an der Entwicklung einer entsprechenden Technologie (http://alert.uni-duisburg.de). An dem Projekt sind auch zwei Medienbeobachtungsuntemehmen beteiligt, die Oberserver Argus Media GmbH aus Baden-Baden und das französische Unternehmen Secodip. Unsere Arbeit würde schon dadurch erleichtert, wenn Informationen, die über unsere Kunden in den Medien erscheinen, vorselektiert würden", beschreibt Simone Holderbach, Leiterin der Produktentwicklung bei Oberserver, ihr Interesse an der Technik. Und wie funktioniert Alert? Das Spracherkennungssystem wird darauf getrimmt, Nachrichtensendungen in Radio und Fernsehen zu überwachen: Alles, was gesagt wird - sei es vom Nachrichtensprecher, Reporter oder Interviewten -, wird durch die automatische Spracherkennung in Text umgewandelt. Dabei werden Themen und Schlüsselwörter erkannt und gespeichert. Diese werden mit den Suchbegriffen des Nutzers verglichen. Gefundene Übereinstimmungen werden angezeigt und dem Benutzer automatisch mitgeteilt. Konventionelle Spracherkennungstechnik sei für die Medienbeobachtung nicht einsetzbar, da diese für einen anderen Zweck entwickelt worden sei, betont Prof. Gerhard Rigoll, Leiter des Fachgebiets Technische Informatik an der Duisburger Hochschule. Für die Umwandlung von Sprache in Text wurde die Alert-Software gründlich trainiert. Aus Zeitungstexten, Audio- und Video-Material wurden bislang rund 3 50 Millionen Wörter verarbeitet. Das System arbeitet in drei Sprachen. Doch so ganz fehlerfrei sei der automatisch gewonnene Text nicht, räumt Rigoll ein. Zurzeit liegt die Erkennungsrate bei 40 bis 70 Prozent. Und das wird sich in absehbarer Zeit auch nicht ändern." Musiküberlagerungen oder starke Hintergrundgeräusche bei Reportagen führen zu Ungenauigkeiten bei der Textumwandlung. Deshalb haben die, Duisburger Wissenschaftler Methoden entwickelt, die über die herkömmliche Suche nach Schlüsselwörtern hinausgehen und eine inhaltsorientierte Zuordnung ermöglichen. Dadurch erhält der Nutzer dann auch solche Nachrichten, die zwar zum Thema passen, in denen das Stichwort aber gar nicht auftaucht", bringt Rigoll den Vorteil der Technik auf den Punkt. Wird beispielsweise "Ölpreis" als Suchbegriff eingegeben, werden auch solche Nachrichten angezeigt, in denen Olkonzerne und Energieagenturen eine Rolle spielen. Rigoll: Das Alert-System liest sozusagen zwischen den Zeilen!' Das Forschungsprojekt wurde vor einem Jahr gestartet und läuft noch bis Mitte 2002. Wer sich über den Stand der Technik informieren möchte, kann dies in dieser Woche auf der Industriemesse in Hannover. Das Alert-System wird auf dem Gemeinschaftsstand "Forschungsland NRW" in Halle 18, Stand M12, präsentiert
