	Lawinenhunde geleistet haben, muss in Zeiten des Massen-Tourismus
	mit technischem Know-how geloest werden. Die Idee von Bela Gipp,
	Jan-Olaf Stiller und Florian Krueger: Ein System, bei dem eine Infrarotkamera
	von einem Modellhubschrauber aus Bilder an ein Leitsystem weitergibt,
	auf dem sich die Temperaturunterschiede zwischen warmen Koerpern
	und Schnee erkennen lassen. Zur Orientierung des Hubschraubers dient
	eine zusaetzliche Echtfarbkamera, ein Ultraschallgeraet fuer schlechte
	Sicht und ein Global Positioning System (GPS). Alles kann mit einem
	Programm, das die jungen Erfinder geschrieben haben, ueber das Internet
	gesteuert und ausgewertet werden."

  abstract = {Jedes Jahr sterben auf deutschen Strassen 7.000 Menschen durch Verkehrsunfaelle.
	Davon koennten ueber 700 vor dem Tod bewahrt werden, wenn die Rettungsdienste
	unverzueglich nach dem Unfall informiert wuerden. Leider kommt es
	immer wieder vor, dass Verunfallte erst nach Minuten oder gar Stunden
	gefunden werden und so wertvolle Zeit bis zur Benachrichtigung der
	Rettungskraefte verstreicht. Warum nicht das flaechendeckend verfuegbare
	Mobilfunknetz nutzen, um automatisch Hilfe herbeizuholen? Urspruenglich
	im Rahmen von Jugend-forscht entwickelten wir in den vergangenen
	zwei Jahren ein flexibles und kostenguenstiges Notrufsystem - den
	"GSM Schutzengel". Dieser sieht aus wie ein gewoehnlicher Mobiltelefonakku,
	enthaelt aber zusaetzlich einen Beschleunigungssensor und einen Mikrokontroller
	zum Auswerten der Messdaten. Mit dieser Technik ist es moeglich,
	jedes handelsuebliche Mobiltelefon zu einem mobilen Schutzengel aufzuruesten,
	der Unfaelle sicher erkennt. Fehlalarme, beispielsweise durch Vollbremsungen
	waehrend der Autofahrt oder Hinunterfallen des Mobiltelefons, sind
	dabei ausgeschlossen. Bei einem Unfall ruft der GSM Schutzengel sofort
	die Rettungskraefte herbei. Dadurch kann selbst bewusstlosen Fahrern
	schnellstmoeglich geholfen werden. Die Position des Unfalls wird
	dabei ueber das Mobilfunknetz bestimmt - bis auf 150 m genau. Somit
	kann zielgenaue Hilfe gewaehrleistet werden, denn wer kann schon
	direkt nach einem Unfall beschreiben, wo genau er ist?}

	berechnet worden, wird aus den vorl�ufigen Ahnlichkeitswerten ein
	endg�ltiger �hnlichkeitswert berechnet. Das Verfahren kann wiederum

	und deren �hnlichkeitswerte zu dem Eingabedokument zu berechnen.
	
	(EN) The invention relates to a computer-implemented method for detecting
	a similarity between at least one input document and a plurality
	of documents. First documents and second documents are detected which
	are directly or indirectly cited by the input document or which directly
	or indirectly cite the input document. At least one preliminary similarity
	value is calculated for every detected document. If more than one
	preliminary similarity value has been calculated for a document,
	a final similarity value is calculated from the preliminary similarity
	values. The method can then be applied to the detected first documents
	and second documents to detect further documents that are similar
	to the input document and to calculate their similarity values to
	the input document.

  abstract = {Various approaches for plagiarism detection exist. All are based on
	more or less sophisticated text analysis methods such as string matching,
	fingerprinting or style comparison. In this paper a new approach
	called Citation-based Plagiarism Detection is evaluated using a doctoral
	thesis, in which a volunteer crowd-sourcing project called GuttenPlag
	identified substantial amounts of plagiarism through careful manual
	inspection. This new approach is able to identify similar and plagiarized
	documents based on the citations used in the text. It is shown that
	citation-based plagiarism detection performs significantly better
	than text-based procedures in identifying strong paraphrasing, translation
	and some idea plagiarism. Detection rates can be improved by combining
	citation-based with text-based plagiarism detection.},

  abstract = {(DE) Die Erfindung betrifft ein Verfahren und ein System zum Bestimmen
	einer �hnlichkeit von zumindest zwei Objekten, welche von einer Baumdatenstruktur
	referenziert werden, wobei das Verfahren zumindest die Schritte -
	Ermitteln der Knoten der mindestens einen Baumdatenstruktur, welche
	die zumindest zwei Objekte referenzieren; - Bestimmen der Distanz
	zwischen jeweils zwei Objekten, welche von den ermittelten Knoten
	jeweils einer Baumdatenstruktur referenziert werden; und - Bestimmen
	eines �hnlichkeitswertes f�r jedes Paar von Objekten unter Verwendung
	der f�r die Objekte eines Paares bestimmten Distanzen ausf�hrt, und

	(EN) The invention relates to a method and system for determining
	a similarity of at least two objects that are referenced by a tree
	data structure, wherein the method performs at least the following
	steps: determining the nodes of the at least one tree data structure
	that reference the at least two objects; determining the distance
	between any two objects that are referenced by the determined nodes
	of a tree data structure; and determining a similarity value for
	each pair of objects using the distances determined for the objects
	of a pair, and wherein the system is equipped to perform the method
	according to the invention.

	entre respectivement deux objets r�f�renc�s par les noeuds d�termin�s
	d'une structure de donn�es arborescente respective; et d�termination
	d'une valeur de similarit� pour chaque paire d'objets au moyen des
	distances d�termin�es pour les objets d'une paire. Le syst�me est
	con�u pour ex�cuter le proc�d� selon l'invention.}
