    Abstract
    Das Internet birgt schier endlose Informationen. Ein zentrales Problem besteht heutzutage darin diese auch zugänglich zu machen. Es ist ein fundamentales Domänenwissen erforderlich, um in einer Volltextsuche die korrekten Suchanfragen zu formulieren. Das ist jedoch oftmals nicht vorhanden, so dass viel Zeit aufgewandt werden muss, um einen Überblick des behandelten Themas zu erhalten. In solchen Situationen findet sich ein Nutzer in einem explorativen Suchvorgang, in dem er sich schrittweise an ein Thema heranarbeiten muss. Für die Organisation von Daten werden mittlerweile ganz selbstverständlich Verfahren des Machine Learnings verwendet. In den meisten Fällen bleiben sie allerdings für den Anwender unsichtbar. Die interaktive Verwendung in explorativen Suchprozessen könnte die menschliche Urteilskraft enger mit der maschinellen Verarbeitung großer Datenmengen verbinden. Topic Models sind ebensolche Verfahren. Sie finden in einem Textkorpus verborgene Themen, die sich relativ gut von Menschen interpretieren lassen und sind daher vielversprechend für die Anwendung in explorativen Suchprozessen. Nutzer können damit beim Verstehen unbekannter Quellen unterstützt werden. Bei der Betrachtung entsprechender Forschungsarbeiten fiel auf, dass Topic Models vorwiegend zur Erzeugung statischer Visualisierungen verwendet werden. Das Sensemaking ist ein wesentlicher Bestandteil der explorativen Suche und wird dennoch nur in sehr geringem Umfang genutzt, um algorithmische Neuerungen zu begründen und in einen umfassenden Kontext zu setzen. Daraus leitet sich die Vermutung ab, dass die Verwendung von Modellen des Sensemakings und die nutzerzentrierte Konzeption von explorativen Suchen, neue Funktionen für die Interaktion mit Topic Models hervorbringen und einen Kontext für entsprechende Forschungsarbeiten bieten können.

    Abstract
    The goal of entity linking is to associate references to an entity that is found in unstructured natural language content to an authoritative inventory of known entities. This article describes the construction of 6 test collections for cross-language person-entity linking that together span 22 languages. Fully automated components were used together with 2 crowdsourced validation stages to affordably generate ground-truth annotations with an accuracy comparable to that of a completely manual process. The resulting test collections each contain between 642 (Arabic) and 2,361 (Romanian) person references in non-English texts for which the correct resolution in English Wikipedia is known, plus a similar number of references for which no correct resolution into English Wikipedia is believed to exist. Fully automated cross-language person-name linking experiments with 20 non-English languages yielded a resolution accuracy of between 0.84 (Serbian) and 0.98 (Romanian), which compares favorably with previously reported cross-language entity linking results for Spanish.
