»Wenn du reisen willst, mußt du die Geschichte dieses Landes kennen und lieben. Das ist ganz unerläßlich. [...] Wag’ es getrost und du wirst es nicht bereuen. Eigentümliche Freuden und Genüsse werden dich begleiten. Du wirst Entdeckungen machen, denn überall wohin du kommst, wirst du, vom Touristenstandpunkt aus, eintreten wie in ›jungfräuliches Land‹. Du wirst Klosterruinen begegnen, von deren Existenz höchstens die nächste Stadt eine leise Kenntnis hatte; du wirst inmitten alter Dorfkirchen, deren zerbröckelter Schindelturm nur auf Elend deutete, große Wandbilder oder in den treppenlosen Grüften reiche Kupfersärge mit Kruzifix und vergoldeten Wappenschildern finden; du wirst Schlachtfelder überschreiten, Wendenkirchhöfe, Heidengräber, von denen die Menschen nichts mehr wissen.«
Die in diesem Bildband gesammelten »Denkmalentdeckungen« verstehen sich als Einladung zu einer Reise durch das Land Brandenburg. Theodor Fontane hatte für ein solches Unternehmen genau den richtigen Blick, als er in seinen »Wanderungen durch die Mark Brandenburg« 1864 diese Sätze schrieb. Auch heute noch sollten wir seiner Anregung zu Begegnungen mit der Geschichte und der Kunstgeschichte des Landes folgen, die uns im Dialog der Kulturen und der Zeiten eine Standortbestimmung in der Gegenwart und eine Orientierung für die Zukunft zugleich bietet.
This contribution presents a quantitative evaluation procedure for Information Retrieval models and the results of this procedure applied on the enhanced Topic-based Vector Space Model (eTVSM). Since the eTVSM is an ontology-based model, its effectiveness heavily depends on the quality of the underlaying ontology. Therefore the model has been tested with different ontologies to evaluate the impact of those ontologies on the effectiveness of the eTVSM. On the highest level of abstraction, the following results have been observed during our evaluation: First, the theoretically deduced statement that the eTVSM has a similar effecitivity like the classic Vector Space Model if a trivial ontology (every term is a concept and it is independet of any other concepts) is used has been approved. Second, we were able to show that the effectiveness of the eTVSM raises if an ontology is used which is only able to resolve synonyms. We were able to derive such kind of ontology automatically from the WordNet ontology. Third, we observed that more powerful ontologies automatically derived from the WordNet, dramatically dropped the effectiveness of the eTVSM model even clearly below the effectiveness level of the Vector Space Model. Fourth, we were able to show that a manually created and optimized ontology is able to raise the effectiveness of the eTVSM to a level which is clearly above the best effectiveness levels we have found in the literature for the Latent Semantic Index model with compareable document sets.
This volume contains the proceedings of the 2nd Workshop on Prosody, Syntax, and Information Structure (WPSI2), held at University of Potsdam on March 18, 2005. WPSI 2 was aimed to discuss issues on the interaction of prosody, syntax, and information structure, from interdisciplinary points of view. The contributors (Haruo Kubozono, Shinichiro Ishihara, Yoshihisa Kitagawa, and Satoshi Tomioka) have been recently working on relevant issues, especially looking at the phenomena related to the intonation of focus and (wh-)questions in Japanese.
Interdisciplinary studies on information structure : ISIS ; Working papers of the SFB 632. - Vol. 8
(2007)
The 8th volume of the working paper series Interdisciplinary Studies on Information Structure (ISIS) of the SFB 632 contains a collection of eight papers contributed by guest authors and SFB-members. The first paper on “Biased Questions” is an invited contribution by Nicholas Asher (CNRS, Laboratoire IRIT) & Brian Reese (University of Texas at Austin). Surveying English tag questions, negative polar questions, and what they term “focus” questions, they investigate the effects of prosody on discourse function and discourse structure and analyze the interaction between prosody and discourse in SDRT (Segmented Discourse Representation Theory). Stefan Hinterwimmer (A2) explores the interpretation of singular definites and universally quantified DPs in adverbially quantified English sentences. He suggests that the availability of a co-varying interpretation is more constrained in the case of universally quantified DPs than in the case of singular definites, because different from universally quantified DPs, co-varying definites are inherently focus-marked. The existence of striking similarities between topic/comment structure and bimanual coordination is pointed out and investigated by Manfred Krifka (A2). Showing how principles of bimanual coordination influence the expression of topic/comment structure beyond spoken language, he suggests that bimanual coordination might have been a preadaptation of the development of Information Structure in human communication. Among the different ways of expressing focus in Foodo, an underdescribed African Guang language of the Kwa family, the marked focus constructions are the central topic of the paper by Ines Fiedler (B1 & D2). Exploring the morphosyntactic facilities that Foodo has for focalization, she suggests that the two focus markers N and n have developed out of a homophone conjunction. Focus marking in another scarcely documented African tone language, the Gur language Konkomba, is treated by Anne Schwarz (B1 & D2). Comparing the two alleged focus markers lé and lá of the language, she argues that lé is better interpreted as a syntactic device rather than as a focus marker and shows that this analysis is corroborated by parallels in related languages. The reflexes of Information Structure in four different European languages (French, German, Greek and Hungarian) are compared and validated by Sam Hellmuth & Stavros Skopeteas (D2). The production data was collected with selected materials of the Questionnaire on Information Structure (QUIS) developed at the SFB. The results not only allow for an evaluation of the current elicitation paradigms, but also help to identify potentially fruitful venues of future research. Frank Kügler, Stavros Skopeteas (D2) & Elisabeth Verhoeven (University of Bremen) give an account of the encoding of Information Structure in Yucatec Maya, a Mayan tone language spoken on the Yucatecan peninsula in Mexico. The results of a production experiment lead them to the conclusion that focus is mainly expressed by syntax in this language. Stefanie Jannedy (D3) undertakes an instrumental investigation on the expressions and interpretation of focus in Vietnamese, a language of the Mon-Khmer family contrasting six lexical tones. The data strongly suggests that focus in Vietnamese is exclusively marked by prosody (intonational emphasis expressed via duration, f0 and amplitude) and that different focus conditions can reliably be recovered. This volume offers insights into current work conducted at the SFB 632, comprising empirical and theoretical aspects of Information Structure in a multitude of languages. Several of the papers mine field work data collected during the first phase of the SFB and explore the expression of Information Structure in tone and non-tone languages from various regions of the world.
