Abstract

Parsing, the syntactic analysis of language, has been studied extensively in computer science and computational linguistics. Computer programs and natural languages share an underlying theory of formal languages and require efficient parsing algorithms. This introductions reviews the thory of parsing from a novel perspective, it provides a formalism to capture the essential traits of a parser that abstracts from the fine detail and allows a uniform description and comparison of a variety of parsers, including Earley, Tomita, LR, Left-Corner, and Head-Corner parsers. The emphasis is on context-free phrase structure grammar and how these parsers can be extended to unification formalisms. The book combines mathematical rigor with high readability and is suitable as a graduate course text

Abstract

The 8th International Conference on Conceptual Structures - Logical, Linguistic, and Computational Issues (ICCS 2000) brings together a wide range of researchers and practitioners working with conceptual structures. During the last few years, the ICCS conference series has considerably widened its scope on different kinds of conceptual structures, stimulating research across domain boundaries. We hope that this stimulation is further enhanced by ICCS 2000 joining the long tradition of conferences in Darmstadt with extensive, lively discussions. This volume consists of contributions presented at ICCS 2000, complementing the volume "Conceptual Structures: Logical, Linguistic, and Computational Issues" (B. Ganter, G.W. Mineau (Eds.), LNAI 1867, Springer, Berlin-Heidelberg 2000). It contains submissions reviewed by the program committee, and position papers. We wish to express our appreciation to all the authors of submitted papers, to the general chair, the program chair, the editorial board, the program committee, and to the additional reviewers for making ICCS 2000 a valuable contribution in the knowledge processing research field. Special thanks go to the local organizers for making the conference an enjoyable and inspiring event. We are grateful to Darmstadt University of Technology, the Ernst Schröder Center for Conceptual Knowledge Processing, the Center for Interdisciplinary Studies in Technology, the Deutsche Forschungsgemeinschaft, Land Hessen, and NaviCon GmbH for their generous support

Abstract

Wie lernen Kinder sprechen? Welche Hinweise geben gerade ihre Fehler beim Spracherwerb auf den Ablauf des Lernprozesses - getreu dem Motto: "Kinder sagen die töllsten Sachen«? Und wie helfen beziehungsweise warum scheitern bislang Computer bei der Simulation neuronaler Netzwerke, die am komplizierten Gewebe der menschlichen Sprache mitwirken? In seinem neuen Buch Wörter und Regeln hat der bekannte US-amerikanische Kognitionswissenschaftler Steven Pinker (Der Sprachinstinkt) wieder einmal eine ebenso informative wie kurzweifige Erkundungstour ins Reich der Sprache unternommen. Was die Sache besonders spannend und lesenswert macht: Souverän beleuchtet der Professor am Massachusetts Institute of Technology sowohl natur- als auch geisteswissenschaftliche Aspekte. So vermittelt er einerseits linguistische Grundlagen in den Fußspuren Ferdinand de Saussures, etwa die einer generativen Grammatik, liefert einen Exkurs durch die Sprachgeschichte und widmet ein eigenes Kapitel den Schrecken der deutschen Sprache". Andererseits lässt er aber auch die neuesten bildgebenden Verfahren nicht außen vor, die zeigen, was im Gehirn bei der Sprachverarbeitung abläuft. Pinkers Theorie, die sich in diesem Puzzle verschiedenster Aspekte wiederfindet: Sprache besteht im Kein aus zwei Bestandteilen - einem mentalen Lexikon aus erinnerten Wörtern und einer mentalen Grammatik aus verschiedenen kombinatorischen Regeln. Konkret heißt das: Wir prägen uns bekannte Größen und ihre abgestuften, sich kreuzenden Merkmale ein, aber wir erzeugen auch neue geistige Produkte, in dem wir Regeln anwenden. Gerade daraus, so schließt Pinker, erschließt sich der Reichtum und die ungeheure Ausdruckskraft unserer Sprache

Rez. in Mitt. VÖB 59(2006) Nr.3, S.75-78 (O. Oberhauser): "Beim vorliegenden Buch handelt es sich um die Festschrift zum 65. Geburtstag des mit Ende des Sommersemesters 2006 in den Ruhestand getretenen Universitätsprofessors für Informationswissenschaft, Harald H. Zimmermann, jenes 1941 in Völklingen geborenen Computerlinguisten, der die Informationswissenschaft als akademische Disziplin in Deutschland mitbegründet und seit 1980 an der Universität des Saarlandes vertreten hat. Die insgesamt 26 Beiträge des von Professor Zimmermanns Mitarbeitern betreuten, optisch gediegen anmutenden Saur-Bandes gliedern sich - so das Inhaltsverzeichnis - in vier Themenschwerpunkte: - Information und Kommunikation - Sprache und Computer, insbesondere Information Retrieval und Automatische Indexierung - Analysen und Entwicklungen - Persönliches Die Aufsätze selbst variieren, wie bei Festschriften üblich bzw. unvermeidbar, hinsichtlich Länge, Stil, thematischem Detail und Anspruchsniveau. Neben wissenschaftlichen Beiträgen findet man hier auch Reminiszenzen und Literarisches. Die nachfolgende Auswahl zeigt, was mich selbst an diesem Buch interessiert hat:
In Thesauri, Semantische Netze, Frames, Topic Maps, Taxonomien, Ontologien - begriffliche Verwirrung oder konzeptionelle Vielfalt? (S. 139-151) gibt Jiri Panyr (München/Saarbrücken) eine gut lesbare und nützliche Übersicht über die im Titel des Beitrags genannten semantischen Repräsentationsformen, die im Zusammenhang mit dem Internet und insbesondere mit dem vorgeschlagenen Semantic Web immer wieder - und zwar häufig unpräzise oder gar unrichtig - Anwendung finden. Insbesondere die Ausführungen zum Modebegriff Ontologie zeigen, dass dieser nicht leichtfertig als Quasi-Synonym zu Thesaurus oder Klassifikation verwendet werden darf. Panyrs Beitrag ist übrigens thematisch verwandt mit jenem von K.-D. Schmitz (Köln), Wörterbuch, Thesaurus, Terminologie, Ontologie (S. 129-137). Abgesehen von dem einfallslosen Titel Wer suchet, der findet? (S. 107- 118) - zum Glück mit dem Untertitel Verbesserung der inhaltlichen Suchmöglichkeiten im Informationssystem Der Deutschen Bibliothek versehen - handelt es sich bei diesem Artikel von Elisabeth Niggemann (Frankfurt am Main) zwar um keinen wissenschaftlichen, doch sicherlich den praktischsten, lesbarsten und aus bibliothekarischer Sicht interessantesten des Buches. Niggemann gibt einen Überblick über die bisherige sachliche Erschliessung der bibliographischen Daten der inzwischen zur Deutschen Nationalbibliothek mutierten DDB, sowie einen Statusbericht nebst Ausblick über gegenwärtige bzw. geplante Verbesserungen der inhaltlichen Suche. Dazu zählen der breite Einsatz eines automatischen Indexierungsverfahrens (MILOS/IDX) ebenso wie Aktivitäten im klassifikatorischen Bereich (DDC), die Vernetzung nationaler Schlagwortsysteme (Projekt MACS) sowie die Beschäftigung mit Crosskonkordanzen (CARMEN) und Ansätzen zur Heterogenitätsbehandlung. Das hier von zentraler Stelle deklarierte "commitment" hinsichtlich der Verbesserung der sachlichen Erschließung des nationalen Online-Informationssystems erfüllt den eher nur Kleinmut und Gleichgültigkeit gewohnten phäakischen Beobachter mit Respekt und wehmutsvollem Neid.
Mit automatischer Indexierung beschäftigen sich auch zwei weitere Beiträge. Indexieren mit AUTINDEX von H.-D. Mass (Saarbrücken) ist leider knapp und ohne didaktische Ambition verfasst, sodass man sich nicht wirklich vorstellen kann, wie dieses System funktioniert. Übersichtlicher stellt sich der Werkstattbericht Automatische Indexierung des Reallexikons zur deutschen Kunstgeschichte von K. Lepsky (Köln) dar, der zeigt, welche Probleme und Schritte bei der Digitalisierung, Indexierung und Web-Präsentation der Volltexte eines grossen fachlichen Nachschlagewerkes anfallen. Weitere interessante Beiträge befassen sich z.B. mit Summarizing-Leistungen im Rahmen eines e-Learning-Projektes (R. Kuhlen), mit dem Schalenmodell und dem Semantischen Web (J. Krause; aus nicht näher dargelegten Gründen in englischer Sprache) und mit der Akkreditierung/ Evaluierung von Hochschullehre und -forschung in Großbritannien (T. Seeger). In Summe liegt hier eine würdige Festschrift vor, über die sich der Gefeierte sicherlich gefreut haben wird. Für informationswissenschaftliche Spezialsammlungen und größere Bibliotheken ist der Band allemal eine Bereicherung. Ein Wermutstropfen aber doch: Obzwar mit Information und Sprache ein optisch ansprechend gestaltetes Buch produziert wurde, enthüllt eine nähere Betrachtung leider allzu viele Druckfehler, mangelhafte Worttrennungen, unkorrigierte grammatikalische Fehler, sowie auch Inkonsistenzen bei Kursivdruck und Satzzeichen. Lektoren und Korrektoren sind, so muss man wieder einmal schmerzlich zur Kenntnis nehmen, ein aussterbender Berufsstand."
