    Ontology-Based Crime News Semantic Retrieval System

    Fiaz Majeed1, Afzaal Ahmad1, Muhammad Awais Hassan2, Muhammad Shafiq3,*, Jin-Ghoo Choi3, Habib Hamam4,5,6,7

    CMC-Computers, Materials & Continua, Vol.77, No.1, pp. 601-614, 2023, DOI:10.32604/cmc.2023.036074

    Abstract Every day, the media reports tons of crimes that are considered by a large number of users and accumulate on a regular basis. Crime news exists on the Internet in unstructured formats such as books, websites, documents, and journals. From such homogeneous data, it is very challenging to extract relevant information which is a time-consuming and critical task for the public and law enforcement agencies. Keyword-based Information Retrieval (IR) systems rely on statistics to retrieve results, making it difficult to obtain relevant results. They are unable to understand the user's query and thus face word mismatches due to context changes… More >

    Une ontologie orientée objet pour la modélisation des socio-écosystèmes

    Éric Masson

    Revue Internationale de Géomatique, Vol.31, No.1, pp. 199-230, 2022, DOI:10.3166/RIG31.199-230

    Abstract This article is a positional paper and an ontological contribution to the modelling of socio-ecosystems (SES). It is also an epistemic position that is anchored on the objectoriented approach. We thus propose a model of knowledge organisation that allows more complexity to be integrated into the multidisciplinary deconstruction and analysis of SES. This object-oriented ontological proposal is based on six concepts of high abstraction level allowing a transdisciplinary portability around the structures, functions, connections, phases, scales and adaptations of SES. After defining our position on object-oriented spatiotemporal modelling, we present the six concepts and explain the interest of a top… More >

    La genèse systémique d’empreinte pour une maîtrise de l’observation de la Terre

    Mireille Fargette1 , Maud Loireau2, Najet Raouani3 , Thérèse Libourel4

    Revue Internationale de Géomatique, Vol.31, No.1, pp. 135-197, 2022, DOI:10.3166/RIG31.135-197

    Abstract This work is interested in observation, in scientific knowledge acquired from what is perceived (Link making Sense) from a complex systemic world. The approach leads to proposing the concept of imprint within the interdisciplinary framework “System – Reality – World as perceived – Model” and testing it against data, then to proposing systemic ontology as an approach. This makes it possible to deploy the Link making Shape from the systemic domain to the world as perceived, to analyze and describe the relevant part in the data and to show how the whole of this mostly symbolic work can contribute, with… More >

    Analyse des empreintes guidée par un modèle de connaissances pour la compréhension des dynamiques de navigation maritime côtière

    Wissame Laddada1 , Éric Saux2

    Revue Internationale de Géomatique, Vol.31, No.1, pp. 111-133, 2022, DOI:10.3166/RIG31.111-133

    Abstract The spatial footprints, historical or acquired in real time, help to understand the dynamics of their carriers. In a context of coastal maritime navigation, the research presented details the approach of setting up a knowledge model aimed at a semantic analysis of ship footprints. This model is defined on the basis of knowledge gathered from experts in this field, supplemented by textual and graphic descriptions. After having described these navigation principles, we present the stages leading to such a knowledge model. The research is completed by the formalization of rules relating to the visibility of landmarks. Finally, a reasoning leads… More >

    Explorer les processus de mobilité passée
    Raisonnement ontologique fondé sur la connaissance des pratiques socioculturelles et des vestiges archéologiques

    Laure Nuninger1 , Thérèse Libourel2, Xavier Rodier3, Rachel Opitz4, Philip Verhagen5, Catherine Fruchart1, Clément Laplaige3, Samuel Leturcq3, Nathanael Levoguer3

    Revue Internationale de Géomatique, Vol.31, No.1, pp. 81-110, 2022, DOI:10.3166/RIG31.81-110

    Abstract In this article we propose an original approach designed by archaeologists and a computer scientist for knowledge creation in studies of movement. Using case studies, we analyze how researchers have identified, conceptualized, and linked the material traces describing various movement processes in a given region. Then, we explain how we construct ontologies that enable us to explicitly relate material elements, identified in the observed landscape, to the knowledge or theory that explains their role and relationships within the movement process. Combining formal pathway systems, so-called « Path framework systems » and informal movement systems, so-called « Pathway systems », through… More >

    Appréhender le changement des catégories pour l’étude d’une dynamique spatiale sur le temps long

    Christine Plumejeaud-Perreau1 , Lucie Nahassia2 , Julie Gravier2

    Revue Internationale de Géomatique, Vol.31, No.1, pp. 47-80, 2022, DOI:10.3166/RIG31.47-80

    Abstract Through three examples coming from long-term studies of population dynamics in France, intra and inter-urban, this paper shows that the introduction of some “a-historical” ontologies was required to implement quantitative analyses of spatial evolutions. However, we demonstrate that these ontologies are far from being neutral, and that they do not dissolve the specificity of the sources we used, but on the contrary, they constitute situated knowledge. Beyond these criticisms, the authors tend to argue that the process of construction and dialogue established around ontology is very beneficial to research, that it is a foundation for an interdisciplinary, shared and sustainable… More >

    Numérique versus symbolique

    Dialogue ontologique entre deux approches

    Hélène Mathian1, Lena Sanders2

    Revue Internationale de Géomatique, Vol.31, No.1, pp. 21-45, 2022, DOI:10.3166/RIG31.21-45

    Abstract The aim of this article is to compare a statistical approach, “geometric data analysis” (GDA), and a simulation approach, the multi-agent systems (MAS), considered as representative, respectively, of a numerical and a symbolic approach of modelling. The case study concerns segregation of scholar space in the Parisian area. First the different steps leading from a thematic question to the development of an operational model to analyze this question are presented. The central and essential role of a conceptual framework at the interface of both is shown. Indeed, before operationalisation, it is necessary to verify the compatibility between the theoretical backgrounds… More >

    Exploring Splicing Variants and Novel Genes in Sacred Lotus Based on RNA-seq Data

    Xinyi Zhang, Zimeng Yu, Pingfang Yang*

    Phyton-International Journal of Experimental Botany, Vol.92, No.6, pp. 1665-1679, 2023, DOI:10.32604/phyton.2023.029482

    Abstract Sacred lotus (Nelumbo nucifera) is a typical aquatic plant, belonging to basal eudicot plant, which is ideal for genome and genetic evolutionary study. Understanding lotus gene diversity is important for the study of molecular genetics and breeding. In this research, public RNA-seq data and the annotated reference genome were used to identify the genes in lotus. A total of 26,819 consensus and 1,081 novel genes were identified. Meanwhile, a comprehensive analysis of gene alternative splicing events was conducted, and a total of 19,983 “internal” alternative splicing (AS) events and 14,070 “complete” AS events were detected in 5,878 and 5,881 multi-exon… More >

    Ontology-Based News Linking for Semantic Temporal Queries

    Muhammad Islam Satti1, Jawad Ahmed2, Hafiz Syed Muhammad Muslim1, Akber Abid Gardezi3, Shafiq Ahmad4, Abdelaty Edrees Sayed4, Salman Naseer5, Muhammad Shafiq6,*

    CMC-Computers, Materials & Continua, Vol.74, No.2, pp. 3913-3929, 2023, DOI:10.32604/cmc.2023.033001

    Abstract Daily newspapers publish a tremendous amount of information disseminated through the Internet. Freely available and easily accessible large online repositories are not indexed and are in an un-processable format. The major hindrance in developing and evaluating existing/new monolingual text in an image is that it is not linked and indexed. There is no method to reuse the online news images because of the unavailability of standardized benchmark corpora, especially for South Asian languages. The corpus is a vital resource for developing and evaluating text in an image to reuse local news systems in general and specifically for the Urdu language.… More >
