- Abstract
- Das Medium Internet ist im Wandel, und mit ihm ändern sich seine Publikations- und Rezeptionsbedingungen. Welche Chancen bieten die momentan parallel diskutierten Zukunftsentwürfe von Social Web und Semantic Web? Zur Beantwortung dieser Frage beschäftigt sich der Beitrag mit den Grundlagen beider Modelle unter den Aspekten Anwendungsbezug und Technologie, beleuchtet darüber hinaus jedoch auch deren Unzulänglichkeiten sowie den Mehrwert einer mediengerechten Kombination. Am Beispiel des grammatischen Online-Informationssystems grammis wird eine Strategie zur integrativen Nutzung der jeweiligen Stärken skizziert.

- Abstract
- This paper reports the design of a Chinese test collection with multilingual queries and the application of this test collection to evaluate information retrieval Systems. The effective indexing units, IR models, translation techniques, and query expansion for Chinese text retrieval are identified. The collaboration of East Asian countries for construction of test collections for cross-language multilingual text retrieval is also discussed in this paper. As well, a tool is designed to help assessors judge relevante and gather the events of relevante judgment. The log file created by this tool will be used to analyze the behaviors of assessors in the future.

- Abstract
- The Specialized Information Services Division (SIS) of the National Library of Medicine (NLM) provides Web access to more than a dozen scientific databases on toxicology and the environment on TOXNET . Search queries on TOXNET often include misspelled or variant English words, medical and scientific jargon and chemical names. Following the example of search engines like Google and ClinicalTrials.gov, we set out to develop a spelling "suggestion" system for increased recall and precision in TOXNET searching. This paper describes development of dictionary technology that can be used in a variety of applications such as orthographic verification, writing aid, natural language processing, and information storage and retrieval. The design of the technology allows building complex applications using the components developed in the earlier phases of the work in a modular fashion without extensive rewriting of computer code. Since many of the potential applications envisioned for this work have on-line or web-based interfaces, the dictionaries and other computer components must have fast response, and must be adaptable to open-ended database vocabularies, including chemical nomenclature. The dictionary vocabulary for this work was derived from SIS and other databases and specialized resources, such as NLM's Unified Medical Language Systems (UMLS) . The resulting technology, A-Z Dictionary (AZdict), has three major constituents: 1) the vocabulary list, 2) the word attributes that define part of speech and morphological relationships between words in the list, and 3) a set of programs that implements the retrieval of words and their attributes, and determines similarity between words (ChemSpell). These three components can be used in various applications such as spelling verification, spelling aid, part-of-speech tagging, paraphrasing, and many other natural language processing functions.

- In den Sozialwissenschaften gibt es zwei fundamental unterschiedliche Auffassungen, was unter Kommunikation zu verstehen ist. Angelehnt an das Alltagsverständnis und daher auch in den Sozialwissenschaften dominant, gehen "handlungstheoretische" Vorstellungen von Kommunikation davon aus, dass diese instrumentellen Charakters ist. Es sind Menschen in ihrer physisch-psychischen Kompaktheit, die mittels Kommunikation, sei dies in mündlicher oder schriftlicher Form, Informationen austauschen. Kommunizierende werden nach dieser Vorstellung wechselseitig als Sender bzw. Empfänger von Informationen verstanden. Kommunikation dient der mehr oder minder erfolgreichen Übertragung von Informationen von Mensch zu Mensch. Davon paradigmatisch zu unterscheiden sind "systemtheoretische" Vorstellungen von Kommunikation, wie sie wesentlich von dem 1998 verstorbenen Soziologen Niklas Luhmann in Vorschlag gebracht wurden. Nach diesem Paradigma wird behauptet, dass ihr "Eigenleben" charakteristisch ist. Kommunikation zeichnet sich durch ihre rekursive Eigendynamik aus, welche die Möglichkeiten der Kommunizierenden begrenzt, diese zu steuern und zu beeinflussen. Gemäß dieser Konzeption befindet sich individuelles Bewusstseins - in ihrer je gedanklichen Eigendynamik - in der Umwelt von Kommunikationssystemen und vermag diese mittels Sprache lediglich zu irritieren, nicht aber kontrollierend zu determinieren. Dies schon deshalb nicht, weil in Kommunikationssystemen, etwa einem Gespräch als einem "Interaktionssystem", mindestens zwei bewusste Systeme mit ihrer je unterschiedlichen gedanklichen Eigendynamik beteiligt sind.

- Abstract
- This paper presents an overview of automatic methods for building domain knowledge structures (domain models) from text collections. Applications of domain models have a long history within knowledge engineering and artificial intelligence. In the last couple of decades they have surfaced noticeably as a useful tool within natural language processing, information retrieval and semantic web technology. Inspired by the ubiquitous propagation of domain model structures that are emerging in several research disciplines, we give an overview of the current research landscape and some techniques and approaches. We will also discuss trade-offs between different approaches and point to some recent trends.

- Abstract
- Text classification (TC) is a core technique for text mining and information retrieval. It has been applied to many applications in many different research and industrial areas. Term-weighting schemes assign an appropriate weight to each term to obtain a high TC performance. Although term weighting is one of the important modules for TC and TC has different peculiarities from those in information retrieval, many term-weighting schemes used in information retrieval, such as term frequency-inverse document frequency (tf-idf), have been used in TC in the same manner. The peculiarity of TC that differs most from information retrieval is the existence of class information. This article proposes a new term-weighting scheme that uses class information using positive and negative class distributions. As a result, the proposed scheme, log tf-TRR, consistently performs better than do other schemes using class information as well as traditional schemes such as tf-idf.

- Abstract
- Natural language processing tasks, such as question answering, machine translation, reading comprehension, and summarization, are typically approached with supervised learning on task-specific datasets. We demonstrate that language models begin to learn these tasks without any explicit supervision when trained on a new dataset of millions of webpages called WebText. When conditioned on a document plus questions, the answers generated by the language model reach 55 F1 on the CoQA dataset - matching or exceeding the performance of 3 out of 4 baseline systems without using the 127,000+ training examples. The capacity of the language model is essential to the success of zero-shot task transfer and increasing it improves performance in a log-linear fashion across tasks. Our largest model, GPT-2, is a 1.5B parameter Transformer that achieves state of the art results on 7 out of 8 tested language modeling datasets in a zero-shot setting but still underfits WebText. Samples from the model reflect these improvements and contain coherent paragraphs of text. These findings suggest a promising path towards building language processing systems which learn to perform tasks from their naturally occurring demonstrations.

- Abstract
- Language barrier is the major problem that people face in searching for, retrieving, and understanding multilingual collections on the Internet. This paper deals with query translation and document translation in a Chinese-English information retrieval system called MTIR. Bilingual dictionary and monolingual corpus-based approaches are adopted to select suitable tranlated query terms. A machine transliteration algorithm is introduced to resolve proper name searching. We consider several design issues for document translation, including which material is translated, what roles the HTML tags play in translation, what the tradeoff is between the speed performance and the translation performance, and what from the translated result is presented in. About 100.000 Web pages translated in the last 4 months of 1997 are used for quantitative study of online and real-time Web page translation

- "Der Spracherkennung am Computer schien vor wenigen Jahren die Zukunft zu gehören. Geradezu euphorisch waren viele Computernutzer, als sich auf den Bildschirmen die ersten gesprochenen Sätze als Text darstellten. Doch die Spracherkennung erwies sich als anfällig, die Nachbearbeitung nahm manchmal mehr Zeit in Anspruch als gespart wurde. Dabei ist die Kommunikation des Menschen mit der Maschine über die Tastatur eigentlich höchst kompliziert - selbst geübte Schreiber sprechen schneller als sie tippen. Deshalb hat sich inzwischen viel getan: Im Preis und in der Genauigkeit sind viele Spracherkennungsprogramme heute alltagsreif. Die besten Systeme kosten aber noch immer mehrere hundert Euro, die günstigsten weisen Lücken auf. Letztlich gilt: Respektable Ergebnisse sind erreichbar, wenn sich der Mensch der Maschine anpasst. Die Stiftung Warentest in Berlin hat die sechs gängigsten Systeme auf den Prüfstand gestellt. Die ersten Ergebnisse waren ernüchternd: Das deutlich gesprochene "Johann Wolfgang von Goethe" wurde als "Juan Wolf kann Mohnblüte", "Jaun Wolfgang von Göbel" oder "Johann-Wolfgang Wohngüte" geschrieben. Grundsätzlich gilt: Bei einem einfachen Basiswortschatz sind die Ergebnisse genau, sobald es etwas spezieller wird, wird die Software erfinderisch. "Zweiter Weltkrieg" kann dann zu "Zeit für Geld kriegt" werden. Doch ebenso wie der Nutzer lernt auch das System. Bei der Software ist Lernfähigkeit Standard. Ohnehin muss der Benutzer das System einrichten, indem er vorgegebene Texte liest. Dabei wird das Programm der Stimme und der Sprechgeschwindigkeit angepasst. Hier gilt, dass der Anwender deutlich, aber ganz normal vorlesen sollte. Wer akzentuiert und übertrieben betont, wird später mit ungenauen Ausgaben bestraft. Erkennt das System auch nach dem Training einzelne Wörter nicht, können sie nachträglich eingefügt werden. Gleiches gilt für kompliziertere Orts- oder Eigennamen. Wie gut das funktioniert, beweist ein Gegentest: Liest ein anderer den selben Text vor, sinkt das Erkennungsniveau rapide. Die beste Lernfähigkeit attestierten die Warentester dem System "Voice Pro 10" von linguatec. Das war das mit Abstand vielseitigste, mit fast 200 Euro jedoch auch das teuerste Programm.

- Abstract
- Khoo, Dai, and Loh examine new statistical methods for the identification of two and three character words in Chinese text. Some meaningful Chinese words are simple (independent units of one or more characters in a sentence that have independent meaning) but others are compounds of two or more simple words. In their segmentation they utilize the Modern Chinese Word Segmentation for Application of Information Processing, with some modifications to focus on meaningful words to do manual segmentation. About 37% of meaningful words are longer than 2 characters indicating a need to handle three and four character words. Four hundred sentences from news articles were manually broken into overlapping bi-grams and tri-grams. Using logistic regression, the log of the odds that such bi/tri-grams were meaningful words was calculated. Variables like relative frequency, document frequency, local frequency, and contextual and positional information, were incorporated in the model only if the concordance measure improved by at least 2% with their addition. For two- and three-character words relative frequency of adjacent characters and document frequency of overlapping bi-grams were found to be significant. Using measures of recall and precision where correct automatic segmentation is normalized either by manual segmentation or by automatic segmentation, the contextual information formula for 2 character words provides significantly better results than previous formulations and using both the 2 and 3 character formulations in combination significantly improves the 2 character results.
