Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Developing an LADM Compliant Dissemination and Visualization System for 3D Spatial Units
No full textThis paper describes research into the visualization of mixed 2D and 3D Cadastre. A schema has been developed to accommodate this data, with provision for a time component. This paper describes the schema, the visualization requirements, and the provision of LADMcompatible views of the data for the purpose of developing these tools, and for the furtherresearch into the schema itself. A significant volume of 2D+t Cadastral data, which also contained 2D+t representations of 3D parcels, is currently incorporated in the Cadastral Database of Queensland. A moderate number of 3D building units, and a smaller number of volumetric parcels have been hand-encoded using bespoke software, and added to this database. The mixture has been displayed in KML through Google Earth. Examples of the database schemas, the encoding practices, LADM-compatible views, and the encoded 2 and 3 dimensional spatial units are included.OLD Department of GIS Technolog
Deriving the Technical Model for the Indoor Navigation Prototype based on the Integration of IndoorGML and LADM Conceptual Model
No full textThis paper shows the conversion of LADM-IndoorGML conceptual model to technical model. The aim of this research is assessing the conceptual model and discovering the possibilities and the shortcomings of the conceptual model via the conversion to technical model. There are three steps to convert the conceptual model:- Prepare the LADM-IndoorGML UML model;- Transform the class diagram to table diagram;- Generate SQL DDL code from the table diagram. During the work from step to step several issues did appear and they are addressed in this paper to enable more automated transformation possibilities from the conceptual model to technical mode. Most of the issues are quite generic and also applicable when converting other conceptual models into technical models. There are a few issues related to our specificconceptual models (IndoorGML and LADM packages) and the Enterprise Architect software (which is the used tool in our case), but most issues are generic: the primary keys that have been created to all tables by the software even if there an ID attributes, foreign keys, the association multiplicity, the attributes multiplicity, data type, spatial data type, index, spatial index, constraints, and inheritance. The research shows that there is a need to develop a complete UML diagram for IndoorGML that contain all the attributes and their datatypes. The current class structure of the code list in LADM standard has been developed for better semantic meaning during the implementation by creating an intermediate conceptual model class to support the transformation. Many critical decisions have been taken during the derivation of the technical model to solve these issues.OLD Department of GIS Technolog
3D Cadastre and LADM - Needs and Expectations towards LADM Revision
No full textThe last decade, significant progress has been made in advancing the concept of 3D Cadastre and related technologies to facilitate its realisation. There are many examples of partial implementation and prototypes of 3D parcels registration around the world as stated by Kitsakis et al (2016) and Dimopoulou et al (2016) regarding selected countries. While standardisation in the land administration domain extends to 3D and even 4D representations, currently, there is no country that has a fully operational 3D Cadastre supporting all stages of the registration and dissemination (Van Oosterom et al, 2014). In the context of 3D Cadastre developments worldwide, the Land Administration Domain Model (LADM), ISO 19152, outlines the foundations for a 3D Cadastre and becomes one of the best candidates for unambiguously representing 3D Rights, Restrictions and Responsibilities (Kalogianni et al, 2017).The spatial development life cycle of an object begins outside the cadastral registration cycle and has a direct impact on how a specific development application is processed. Thus, in considering the changes required to allow a jurisdiction to register 3D objects, it is important to note the sphere of influence that could have an impact on 3D registration. These include multiple stakeholders and processes, which generate different user needs, as addressed at the previous section and also new opportunities that could be addressed on the current LADM version.To this purpose, this paper explores the needs and prospects towards further 3D modelling of the present LADM version, as derived by the current LADM experience in various countries worldwide in the context of the full spatial development cycle. Nevertheless, over the last few years the number of jurisdictions that are developing LADM-based country profiles,prototype systems and undertaking pilots using various physical models and data formats to achieve LADM implementation in the context of 3D Cadastre has become more significant.Those approaches can be mainly categorised as “fully operational” implementations and “partly-operational” implementations focusing on different aspects of 3D cadastre development cycle; e.g. submission of 3D survey plans, prototype stage; implementations that focus on visualisation, implementations that focus on constraints and validation rules, etc. Finally, within this context, this paper examines how current LADM version can efficiently meet the needs stated above and update user requirements for LADM in the context of the upcoming revision.OLD Department of GIS Technolog
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
3D Cadastral Lifecycle: An Information Delivery Manual ISO 29481 for 3D Data Extraction from the Building Permit Application Process
No full textThe lifecycle of a 3D cadastral spatial unit and its associated rights, restrictions and responsibilities is made up of many different parts and substages (Van Oosterom 2013). Onepart could be the extraction of 3D data from building permit application process. This paper looks at how this process could be coordinated with a number of other processes and the 3D data used for a variety of purposes including testing conformance to building regulations, rates assessment, inclusion in a national topographic map and asset management. Anassociated use case narrows the scope and illustrates how software which uses the Design and Engineering Methodology for Organisations (DEMO) (Dietz 2006) as reference can be used to facilitate this process.OLD Department of GIS Technolog
