Analysis and Assessment of Cross-Language Question Answering Systems
Juncal Gutiérrez-Artacho (University of Granada, Spain) and María-Dolores Olvera-Lobo (CSIC, Unidad Asociada Grupo SCImago and University of Granada, Spain)

Within the sphere of the Web, the overload of information is more notable than in other contexts. Question answering systems (QAS) are presented as an alternative to the traditional Information Retrieval (IR) systems, seeking to offer precise and understandable answers to factual questions instead of showing the user a list of documents related to a given search . Given that the QAS is presented as a substantial advance in the improvement of IR, it becomes necessary to determine its effectiveness for the final user. With this aim, 7 studies were undertaken to evaluate: a) in the first two, the linguistic resources and tools used in these systems for multilingual retrieval (Research 1; Research 2); and b) the performance and quality of the answers of the main monolingual and multilingual QA of general domain and specialized domain in the Web in response to different types of questions and subjects, so that different evaluation means can be applied (Research 3, Research 4, Research 5, Research 6, Research 7).

Sustainability of Agriculture Territories in South Kazakhstan: Remote Sensing and Geodata for Design of Landscape and Soil Maps
A mathematically defined, reduced, generalized image of the surface of the Earth, another celestial body, or outer space, showing the objects located or projected onto them in the adopted system of conventional signs. The map is considered as a figurative and symbolic model with high information content, spatiotemporal similarity with respect to the original, metricity, special visibility and visualization, which makes it the most important means of knowledge in Earth sciences and socio-economic sciences.
