Hash Codes

Cross-modal hashing intends to project data from two modalities into a common hamming space to perform cross-modal retrieval efficiently. Despite satisfactory performance achieved on real applications, existing methods are incapable of effectively preserving semantic structure to maintain inter-class relationship and improving discriminability to make intra-class samples aggregated simultaneously, which thus limits the higher retrieval performance. To handle this problem, we propose Equally-Guided Discriminative Hashing (EGDH), which jointly takes into consideration semantic structure and discriminability. Specifically, we discover the connection between semantic structure preserving and discriminative methods. Based on it, we directly encode multi-label annotations that act as high-level semantic features to build a common semantic structure preserving classifier. With the common classifier to guide the learning of different modal hash functions equally, hash codes of samples are intra-class aggregated and inter-class relationship preserving. Experimental results on two benchmark datasets demonstrate the superiority of EGDH compared with the state-of-the-arts.

Nominal Compounds

This study addresses agentive nominal compounds in French and Swedish containing N and V constituents. French has only one such compound, VN, whereas Swedish has at least four, NV-are, NV-a, NV and VN. The study explores the semantic characteristics of their constituents and their semantic structures. Formal aspects are also considered within a lexeme-based morphology. The analysis shows that, although French and Swedish compounds differ formally, they share more or less the same semantics. Their V constituent takes one or more arguments, and their N constituents display several semantic roles. Semantically, the compounds generally denote an Actor of verbs taking two arguments, and the N constituents denote an Undergoer, except in Swedish VN compounds, which denote an entity which fills the same role as that of the N constituent, generally an Actor. Non argumental interpretations, such as Place or Event, are less frequent. In conclusion, the study can have typological value for the semantics of agentive nominal compounds.1

The article considers the functions of the system of verbal imagery’s in the creation of the scientific style of V.V. Vinogradov. The figurativeness of basic, background and metaphorical terms is described. The semantic structure of the image of the basic term «style» is analyzed, figurative paradigms of the concepts Language, Speech and Style are revealed. The article shows the relationship between scientific thinking and metaphorical style, the role of sustainable cognitive metaphors in the creation, storage and transfer of pragmatic information and the creation of a cultural and historical context.

The attention of modern linguistics to the study of verbal representatives of the mental essence (both individual and collective one) of the native speakers involves an appeal to all subsystems of the national language where territorial dialects take a significant part. The analysis of dialect linguistic units possessing linguistic and cultural value is considered as a necessary way for the study of people’s worldview and perception of the world, national mentality as a whole. The ability of stable phrases (phraseological units) to preserve and express a native speaker’s attitude to the world around them is the basis for the use of the analysis of folk phraseology as a way of penetration into a speaker’s spiritual world. Volumetric representation of the external and internal peculiarities of stable phrases allows the author to get their systematization in the form of phraseosemantic field consisting of different kinds singled out in phraseosemantic groups. The article deals with stable phrases of synonymic value recorded in the Dictionary of Smolensk dialects and stable phrases forming a phraseosemantic group. These phrases are analyzed taking into account the semantic structure of the key word, the characteristics of the dependent word, and the method of forming phraseological semantics. On the example of the analysis of phrases with the key word «bit’» and a synonymic series with the semantic dominant «bezdel’nichat’», the article discusses the peculiarities of phraseological nomination in Smolensk dialects and confirms a high level of connotativity and evaluation in the folk phraseology.
