Abstract

Purpose - The purpose of this paper is to discuss the second edition of the Encyclopaedia Judaica (2007) within its broader historical context of the production of encyclopedias in the twentieth and the twenty-first centuries. The paper contrasts the 2007 edition of the Encyclopaedia Judaica to the Jewish Encyclopedia published between 1901 and 1905, and to the first edition of the Encyclopaedia Judaica published in 1972; then contrasts the 2007 edition of the Encyclopaedia Judaica to Wikipedia and to other projects of online encyclopedias. Design/methodology/approach - The paper provides a personal reflective review of the sources in question. Findings - That Encyclopaedia Judaica in its latest edition does not adequately replace the original first edition in terms of depth of scholarly work. It is considered that the model offered by Wikipedia could work well for the Encyclopaedia Judaica, allowing it to retain the core of the expert knowledge, and at the same time channel the energy of volunteer editors which has made Wikipedia such a success. Practical implications - The paper is of interest to those with an interest in encyclopedia design or Jewish studies. Originality/value - This paper provides a unique reflection on the latest edition of the encyclopedia and considers future models for its publication based on traditional and non-traditional methods.

Abstract

Studies the effects of typeface, point size, screnn resolution and monitor size on legibility in a task-setting similar to skimming headlines in an electronic newspaper. Studies Times New Roman, Book Antiqua, Century Gothic, and Arial typefaces. The headlines were shown to 28 subjects using a brief-exposure method. The results indicate the existence of interactions between all factors considered in this study. The best overall legibility was achieved by the Times New Roman and Arial typefaces. These 2 typefaces represent a serif and sans-serif typeface tuned specifically for the display of text on a computer screen

Abstract

Fine-grained financial sentiment analysis on news headlines is a challenging task requiring human-annotated datasets to achieve high performance. Limited studies have tried to address the sentiment extraction task in a setting where multiple entities are present in a news headline. In an effort to further research in this area, we make publicly available SEntFiN 1.0, a human-annotated dataset of 10,753 news headlines with entity-sentiment annotations, of which 2,847 headlines contain multiple entities, often with conflicting sentiments. We augment our dataset with a database of over 1,000 financial entities and their various representations in news media amounting to over 5,000 phrases. We propose a framework that enables the extraction of entity-relevant sentiments using a feature-based approach rather than an expression-based approach. For sentiment extraction, we utilize 12 different learning schemes utilizing lexicon-based and pretrained sentence representations and five classification approaches. Our experiments indicate that lexicon-based N-gram ensembles are above par with pretrained word embedding schemes such as GloVe. Overall, RoBERTa and finBERT (domain-specific BERT) achieve the highest average accuracy of 94.29% and F1-score of 93.27%. Further, using over 210,000 entity-sentiment predictions, we validate the economic effect of sentiments on aggregate market movements over a long duration.

Abstract

Suchmaschinen sind der wichtigste Zugangsweg zum Auffinden neuer Netzinhalte. Insgesamt verwendeten nach einer repräsentativen Studie im dritten Quartal 2005 fast 85 Prozent der deutschen Internetnutzer Suchmaschinen. Diese sind inzwischen auch ein Big Business: Gemessen am Börsenwert ist die Suchmaschine Google mit einem Gesamtwert von 80 Mrd. Dollar das wertvollste Medienunternehmen der Welt. Der Konzerngewinn stieg von 2004 auf 2005 um 367 Prozent auf 1,5 Mrd. Dollar. Als Gatekeeper im Internet stellen die Suchmaschinen eine zentrale Herausforderung für Wissenschaft und Forschung dar - letztlich geht es um die Frage der "digitalen Informationsmacht". Mit diesem Band liegt erstmals eine Publikation vor, die die Rolle von Suchmaschinen in der Informationsgesellschaft in den wichtigsten Dimensionen aus verschiedenen Perspektiven wissenschaftlich beleuchtet und dabei hilft, die künftige Suchmaschinenforschung zu systematisieren.

Der Band geht auf die internationale Tagung Die wachsende Macht von Suchmaschinen im Internet: Auswirkungen auf User, Medienpolitik und Medienbusiness bestehend aus einem interdisziplinären wissenschaftlichen Workshop am 26. Juni 2006 und einer Publikumskonferenz am 27. Juni 2006 in Berlin zurück, die vom Lehrstuhl für Journalistik II der Universität Leitung und dem Lehrstuhl für Internationalen Journalismus der UniversitSt Dortmund in Kooperation mit der Friedrich-Ebert-Stiftung, Bereich Medien und Politik, veranstaltet worden ist. In drei Kapiteln werden die zentralen Forschungsfelder aufgegriffen: Das erste Kapitel behandelt die wichtigsten Aspekte im Bereich der Suchmaschinenregulierung und -ökonomie. Es werden Herausforderungen transparent gemacht, die sich gegenwärtig in der Entwicklung befindlichen Regulierungsstrukturen analysiert und Lösungswege erarbeitet. Das zweite Kapitel beschäftigt sich, zum ersten Mal in Form einer Publikation, mit dem Verhältnis von Suchmaschinen und Journalismus. Dabei ist die Frage, inwieweit Suchmaschinen einerseits journalistische Funktionen übernehmen und andererseits Journalisten als Rechercheinstrument dienen und wie sich hierdurch das Gefüge des bisherigen Massenkommunikationssystems verändert, von entscheidender Bedeutung.
Im dritten Kapitel werden die Qualität von Suchmaschinen und das Nutzerverhalten näher beleuchtet. Erkenntnisse über die Güte von Suchmaschinen sind von großer Relevanz, um deren Rolle bei der Informationsvermittlung in einer Gesellschaft angemessen beurteilen zu können. Der Band liefert hier neue Ansätze und Vorschläge, da die Frage nach der Qualität von Suchmaschinen noch nicht ausreichend beantwortet worden ist. Zum anderen ist die Analyse des Nutzerverhaltens grundlegend, um Schlussfolgerungen für die Medienkompetenz als zentrale Schlüsselqualifikation im Informationszeitalter ziehen zu können. Unter den Autoren sind viele der international führende Experten auf dem Gebiet Suchmaschinen, darunter Wissenschaftler der Universitäten Harvard, Yale und Columbia sowie der London School of Economics und der Pariser Sorbonne. Darüber hinaus wurden auch Beiträge von Praktikern, allesamt leitende Redakteure oder Verantwortliche in Medienunternehmen aufgenommen, um deren Erkenntnisse für die Thematik fruchtbar zu machen. Der Band richtet sich neben der Wissenschaft auch an die Praxis, vor allem die Medienaufsicht und -ökonomie sowie an den Journalismus. Er bietet aber auch der allgemein interessierten Öffentlichkeit einen fundierten Einblick in die bisher wenig erforschte Welt der Suchmaschinen.

Abstract

Comprehensiveness and consistency in newspaper indexing depend on the effectiveness of subject analysis of the news items. Discusses indexing skills required in order to identify indexable concepts. Describes practical aspects of conceptual analysis, crystalises criteria and methods for the indexing of news stories, and eludicates reasons form providing multiple subject-entries for certain news items. Suggests rules for news analysis and speedy and accurate allocation of subject headings, and illustrates the technique of dealing with complex and diversified news headings reported at intervals. As the headlines do not always indicate the real subject of a news story, the identification of indexable concepts can become arduous and cumbersome. Discusses the methods, skills and capability needed to tackle such problems
