Integrating distributional and lexical information for semantic classification of words using MRMF
(2016)
Semantic classification of words using distributional features is usually based on the semantic similarity of words. We show on two different datasets that a trained classifier using the distributional features directly gives better results. We use Support Vector Machines (SVM) and Multirelational Matrix Factorization (MRMF) to train classifiers. Both give similar results. However, MRMF, that was not used for semantic classification with distributional features before, can easily be extended with more matrices containing more information from different sources on the same problem. We demonstrate the effectiveness of the novel approach by including information from WordNet. Thus we show, that MRMF provides an interesting approach for building semantic classifiers that (1) gives better results than unsupervised approaches based on vector similarity, (2) gives similar results as other supervised methods and (3) can naturally be extended with other sources of information in order to improve the results.
The CogALex-V Shared Task provides two datasets that consists of pairs of words along with a classification of their semantic relation. The dataset for the first task distinguishes only between related and unrelated, while the second data set distinguishes several types of semantic relations. A number of recent papers propose to construct a feature vector that represents a pair of words by applying a pairwise simple operation to all elements of the feature vector. Subsequently, the pairs can be classified by training any classification algorithm on these vectors. In the present paper we apply this method to the provided datasets. We see that the results are not better than from the given simple baseline. We conclude that the results of the investigated method are strongly depended on the type of data to which it is applied.
In distributional semantics words are represented by aggregated context features. The similarity of words can be computed by comparing their feature vectors. Thus, we can predict whether two words are synonymous or similar with respect to some other semantic relation. We will show on six different datasets of pairs of similar and non-similar words that a supervised learning algorithm on feature vectors representing pairs of words outperforms cosine similarity between vectors representing single words. We compared different methods to construct a feature vector representing a pair of words. We show that simple methods like pairwise addition or multiplication give better results than a recently proposed method that combines different types of features. The semantic relation we consider is relatedness of terms in thesauri for intellectual document classification. Thus our findings can directly be applied for the maintenance and extension of such thesauri. To the best of our knowledge this relation was not considered before in the field of distributional semantics.
Diese Literaturrecherche versucht eine Darstellung des Leseprozesses sowie der Leichten Sprache, die Menschen mit Lesestörungen dienen soll.
Es stellt sich heraus, dass künftig ein anderes System erforderlich sein wird, das es gestattet, Leserkategorien und Lernprozesse zu berücksichtigen.
Die Entwicklung einer Alternative auf der Basis einer geregelten Sprache (controlled language) könnte im Unterschied zur Leichten Sprache Dokumenttypen, Leserkategorien, Wort- und Grammatikkenntnisse sowie das beim Leser vorhandene Wissen berücksichtigen.
Research question: Rivalries in team sports are commonly conceptualized as a threat to the fans’ identity. Therefore, past research has mainly focused on the negative consequences. However, theoretical arguments and empirical evidence suggest that rivalry has both negative and positive effects on fans’ self-concept. This research develops and empirically tests a model which captures and integrates these dual effects of rivalry.
Research methods: Data were collected via an on-site survey at home games of eight German Bundesliga football teams (N = 571). Structural equation modeling provides strong support for the proposed model.
Results and findings: In line with previous research, the results show that rivalry threatens fans’ identity as reflected in lower public collective self-esteem in relation to supporters of the rival team. However, the results also show that there are crucial positive consequences, such as higher perceptions of public collective self-esteem in relation to supporters of non-rival opponents, perceived ingroup distinctiveness and ingroup cohesion. These positive effects are mediated through increases in disidentification with the rival and perceived reciprocity of rivalry.
Implications: We contribute to the literature by providing a more balanced view of one of team sports’ key phenomena. Our results indicate that the prevalent conceptualization of rivalry as an identity threat should be amended by the positive consequences. Our research also offers guidance for the promotion of rivalries, where the managerial focus should be on creating a perception that a rivalry is reciprocal.
According to the third-person effect or the influence of presumed media influence approach, the presumption that the media has strong effects on other people can affect individuals’ attitudes and behavior. For instance, if people believe in strong media influences on others, they are more likely to increase their communication activities or support demands for restrictions on media. A standardized online survey among German journalists (N = 960) revealed that the stronger the journalists perceive the political online influence on the public to be, the more frequently they contradict unwanted political views in their articles. Moreover, even journalists are more likely to approve of restrictions on the Internet’s political influence, the stronger they believe the effects of online media to be. The data reveal no connections between communication activities and demands for restrictions.
Smart Cities require reliable means for managing installations that offer essential services to the citizens. In this paper we focus on the problem of evacuation of smart buildings in case of emergencies. In particular, we present an abstract architecture for situation-aware evacuation guidance systems in smart buildings, describe its key modules in detail, and provide some concrete examples of its structure and dynamics.

Surface atomic relaxation and magnetism on hydrogen-adsorbed Fe(110) surfaces from first principles
(2016)
We have computed adsorption energies, vibrational frequencies, surface relaxation and buckling for hydrogen adsorbed on a body-centred-cubic Fe(110) surface as a function of the degree of H coverage. This adsorption system is important in a variety of technological processes such as the hydrogen embrittlement in ferritic steels, which motivated this work, and the Haber–Bosch process. We employed spin-polarised density functional theory to optimise geometries of a six-layer Fe slab, followed by frozen mode finite displacement phonon calculations to compute Fe–H vibrational frequencies. We have found that the quasi-threefold (3f) site is the most stable adsorption site, with adsorption energies of ∼3.0 eV/H for all coverages studied. The long-bridge (lb) site, which is close in energy to the 3f site, is actually a transition state leading to the stable 3f site. The calculated harmonic vibrational frequencies collectively span from 730 to 1220 cm−1, for a range of coverages. The increased first-to-second layer spacing in the presence of adsorbed hydrogen, and the pronounced buckling observed in the Fe surface layer, may facilitate the diffusion of hydrogen atoms into the bulk, and therefore impact the early stages of hydrogen embrittlement in steels.
Sehen ist für den Menschen eine besonders wichtige Form der Wahrnehmung. Über den Sehsinn nimmt der Mensch ca. 80 Prozent seiner Informationen auf, sodass „etwa ein Viertel des gesamten Gehirns und 60 Prozent der Großhirnrinde, dem Sitz höherer Hirnfunktionen, mit der Analyse der sichtbaren Welt beschäftigt ist“ (Simm, 2011). Sogar auf unsere Sprache hat das Sehen einen großen Einfluss ausgeübt. So bezeichnet man auch nicht visuelle Dinge oder Darbietungen als farblos, wenn diesen „aus unserer Sicht eine bestimmt Qualität fehlt“ (Erb, 1998, S. 1). Die große Bedeutung des Sehsinns erkannte natürlich auch Aristoteles. Er widmete dem Sehen daher einige Gedanken, die überwiegend in de anima (II 7, 418a 26 – 419b 3), aber auch in de sensu (439a 21 bis 447a 11) zu finden sind. Eine besondere Schwierigkeit der Erklärung der visuellen Wahrnehmung besteht darin, dass im Unterschied zum Fühlen, Riechen und Hören unklar ist, welches Medium zur Übertragung der Sehinformationen vom Objekt ins Auge des Betrachters verwendet wird bzw. wie diese Übertragung eventuell auch ohne klar erkennbares Medium funktionieren kann.
Das Ziel dieser Arbeit ist es also, Aristoteles´ Auffassung des Sehvorganges und des hierzu benötigten Übertragungsmediums zu analysieren. Hierzu wird zunächst versucht, die teilweise schwer verständlichen und teilweise auch widersprüchlichen Ausführungen Aristoteles´ systematisch aufzuarbeiten und klar und einfach darzustellen. Dabei wird sich diese Arbeit auf das Sehen im
physikalischen Sinne beschränken, also darauf wie es gelingen kann, dass Informationen über die reale Welt optisch bis zum Auge gelangen und somit der Wahrnehmung zur Verfügung stehen.
