    Abstract
    Jetzt scheint es allmählich ans Eingemachte zu gehen. Ein von der chinesischen Alibaba-Gruppe entwickelte KI-Programm konnte erstmals Menschen in der Beantwortung von Fragen und dem Verständnis von Text schlagen. Die chinesische Regierung will das Land führend in der Entwicklung von Künstlicher Intelligenz machen und hat dafür eine nationale Strategie aufgestellt. Dazu ernannte das Ministerium für Wissenschaft und Technik die Internetkonzerne Baidu, Alibaba und Tencent sowie iFlyTek zum ersten nationalen Team für die Entwicklung der KI-Technik der nächsten Generation. Baidu ist zuständig für die Entwicklung autonomer Fahrzeuge, Alibaba für die Entwicklung von Clouds für "city brains" (Smart Cities sollen sich an ihre Einwohner und ihre Umgebung anpassen), Tencent für die Enwicklung von Computervision für medizinische Anwendungen und iFlyTec für "Stimmenintelligenz". Die vier Konzerne sollen offene Plattformen herstellen, die auch andere Firmen und Start-ups verwenden können. Überdies wird bei Peking für eine Milliarde US-Dollar ein Technologiepark für die Entwicklung von KI gebaut. Dabei geht es selbstverständlich nicht nur um zivile Anwendungen, sondern auch militärische. Noch gibt es in den USA mehr KI-Firmen, aber China liegt bereits an zweiter Stelle. Das Pentagon ist beunruhigt. Offenbar kommt China rasch vorwärts. Ende 2017 stellte die KI-Firma iFlyTek, die zunächst auf Stimmerkennung und digitale Assistenten spezialisiert war, einen Roboter vor, der den schriftlichen Test der nationalen Medizinprüfung erfolgreich bestanden hatte. Der Roboter war nicht nur mit immensem Wissen aus 53 medizinischen Lehrbüchern, 2 Millionen medizinischen Aufzeichnungen und 400.000 medizinischen Texten und Berichten gefüttert worden, er soll von Medizinexperten klinische Erfahrungen und Falldiagnosen übernommen haben. Eingesetzt werden soll er, in China herrscht vor allem auf dem Land, Ärztemangel, als Helfer, der mit der automatischen Auswertung von Patientendaten eine erste Diagnose erstellt und ansonsten Ärzten mit Vorschlägen zur Seite stehen.

    "Die Computerlinguistik vereinigt Elemente von Informatik und Linguistik; sie verwendet darüber hinaus Methoden aus weiteren Gebieten wie Mathematik, Psychologie, Statistik und künstliche Intelligenz. Der Reiz und die Herausforderung einer solchen interdisziplinären Wissenschaft liegen darin, Analogien zwischen Konzepten aus weit entfernten Teilgebieten zu erkennen und zu nutzen. Paradebeispiel dafür ist einer der entscheidenden Durchbrüche, welche die Computerlinguistik prägten. Es geht um das »Parsing«: Ein Computerprogramm, genauer gesagt ein Compiler, nimmt Zeichen für Zeichen den Input des Benutzers entgegen, der in diesem Fall seinerseits aus dem Text eines Computerprogramms besteht, und ermittelt dessen Struktur. Im Prinzip dasselbe tut ein Mensch, der einen gesprochenen Satz hört und versteht."

    "Die Heilige Schrift gibt es nicht nur in mehreren hundert Sprachen, sondern oft innerhalb eines Sprachraums auch in mehreren Varianten. Britische Leser konnen unter anderem zwischen der bewusst sehr einfach geschriebenen Bible in Basic English und der linguistisch komplexen King James Version aus dem 17. Jahrhundert wahlen. Die Fassungen unterscheiden sich in Satzlänge, Wortwahl sowie Förmlichkeit und sprechen so Menschen aus verschiedenen Kulturen und mit unterschiedlichem Bildungsstand an. Ein Team um Keith Carlson vom Dartmouth College will die insgesamt 34 englischsprachigen Versionen der Bibel nun dazu nutzen, um Computern unterschiedliche Stilformen beizubringen Bisher übersetzen entsprechende Programme zwar Fremdsprachen, zum Teil mit beeindruckender Genauigkeit. Oft scheitern sie aber, wenn sie einen Text zielsicher stilistisch verändern sollen, vor allem wenn es dabei um mehr als ein einzelnes Merkmal wie beispielsweise die Komplexität geht. Die Bibel eigne sich mit ihren rund 31 000 Versen wie kein anderes Werk für das Training von Übersetzungsprogrammen, argumentiert das Team um Carlson. Schließlich seien alle Fassungen sehr gewissenhaft von Menschen übersetzt und außerdem Vers für Vers durchnummeriert worden. Das erleichtere einer Maschine die Zuordnung und sei bei anderen umfangreichen Schriftquellen wie dem Werk von William Shakespeare oder der Wikipedia nicht zwangsläufig der Fall. Als erste Demonstration haben die Forscher zwei Algorithmen, von denen einer auf neuronalen Netzen basierte, mit acht frei im Internet verfügbaren Bibelversionen trainiert. Anschließend testeten sie, wie gut die beiden Programme Verse der Vorlagen in einen gewünschten Stil übertrugen, ohne dass die Software auf die anvisierte Fassung der Bibel zugreifen konnte. Insgesamt seien die automatischen Übersetzer dem Ziel schon recht nahegekommen, berichten die Forscher. Sie sehen ihre Arbeit aber erst als Startpunkt bei der Entwicklung einer künstlichen Intelligenz, die souverän zwischen verschiedenen Sprachstilen wechseln kann."

    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.

    Abstract
    This research creates an architecture for investigating the existence of probable lexical divergences between articles, categorized as Institute for Scientific Information (ISI) and non-ISI, and consequently, if such a difference is discovered, to propose the best available classification method. Based on a collection of ISI- and non-ISI-indexed articles in the areas of business and computer science, three classification models are trained. A sensitivity analysis is applied to demonstrate the impact of words in different syntactical forms on the classification decision. The results demonstrate that the lexical domains of ISI and non-ISI articles are distinguishable by machine learning techniques. Our findings indicate that the support vector machine identifies ISI-indexed articles in both disciplines with higher precision than do the Naïve Bayesian and K-Nearest Neighbors techniques.
