Druck auf Anfrage Neuware - Printed after ordering - Studienarbeit aus dem Jahr 2010 im Fachbereich Didaktik - BWL, Wirtschaftspädagogik, Note: 1,7, Johann Wolfgang Goethe-Universität Frankfurt am Main, Sprache: Deutsch, Abstract: Die vorliegende Arbeit beschäftigt sich mit der Auswertung drei wesentlicher Methoden zur Analyse von Textmaterial. Diese Methoden stammen allesamt von Wissenschaftlern mit dem Ziel, zukünftig valide Prognosen über den Einfluss einer Neuveröffentlichung zu treffen. Die erste Ausarbeitung mit dem Titel 'When is a Liability not a Liability Textual analysis, Dictionairies, and 10-Ks' (LoughranMcDonald 2009) befasst sich mit der Auswertung von Texten mittelsWörterbüchern. Die zweite Arbeit namens 'Using news articles to predict stock price movements' (Gidófalvi 2001) untersucht den Einfluss von Finanz- und Unternehmensnachrichten auf 12 Aktienkurse des NASDAQ-Index. Dabei wird als Algorithmus der naive Bayes-Textklassifikator verwendet, der aufgrund seiner einfachen und praktischen Anwendbarkeit häufig von Wissenschaftlern zur Klassifizierung von Nachrichten benutzt wird. Schließlich beschäftigt sich die dritte Ausarbeitung mit dem Titel 'Kursrelevanzprognose von Ad-hoc-Meldungen' (Schulz, Spilipoulou, Winkler 2003) mit dem Einfluss mitteilungspflichtigerUnternehmensnachrichten auf deren Aktienkurse, um zukünftige Prognosen vorherzusagen.Das Ziel dieser Ausarbeitung ist die Analyse der konzeptionellen Vorgehensweise der drei Veröffentlichungen. Es soll dargelegt werden, wie die Methodik der Modelle als auch die Metrik der Auswertung der Ergebnisse bei allen drei Arbeiten sind. Dabei soll anhand der Systematiken anderer Wissenschaftler eine Beurteilung undgegebenenfalls Erweiterung der einzelnen Modelle erfolgen.…

Information regarding the right of withdrawal
Statutory right to withdraw
You have the right to withdraw from this contract within 14 days without giving any reason.
The withdrawal period will expire after 14 days from the day on which you acquire, or a third party other than the carrier and indicated by you acquires, physical possession of the last good or the last lot or piece.
To exercise the right of withdrawal, electronically fill in and submit a clear statement on our website, under "My Purchases" in "My Account". We will communicate to you an acknowledgement of receipt of such a withdrawal on a durable medium (e.g. by e-mail) without delay.
To meet the withdrawal deadline, it is sufficient for you to send your communication concerning your exercise of the right of withdrawal before the withdrawal period has expired.
Effects of withdrawal
If you withdraw from this contract, we will reimburse to you all payments received from you, including the costs of delivery (except for the supplementary costs arising if you chose a type of delivery other than the least expensive type of standard delivery offered by us).
We may make a deduction from the reimbursement for loss in value of any goods supplied, if the loss is the result of unnecessary handling by you.
We will make the reimbursement without undue delay, and not later than 14 days after the day on which we are informed about your decision to withdraw from this contract.
We will make the reimbursement using the same means of payment as you used for the initial transaction, unless you have expressly agreed otherwise; in any event, you will not incur any fees as a result of such reimbursement.
We may withhold reimbursement until we have received the goods back, or you have supplied evidence of having sent back the goods, whichever is the earliest.
You shall send back the goods or hand them over to AHA-BUCH GmbH, Einbeck, Germany, without undue delay and in any event not later than 14 days from the day on which you communicate your withdrawal from this contract to us. The deadline is met if you send back the goods before the period of 14 days has expired. You will have to bear the direct cost of returning the goods. You are only liable for any diminished value of the goods resulting from the handling other than what is necessary to establish the nature, characteristics and functioning of the goods.

The right of withdrawal does not apply to:
- The delivery of newspapers, journals or magazines with the exception of subscription contracts; and
- The supply of digital content which is not supplied on a tangible medium (e.g. on a CD or DVD) if you accepted when you placed your order that we could start to deliver it, and that you could not withdraw once delivery had started.
