Il progetto OnToMap: costruire conoscenza territoriale attraverso l'uso di un'applicazione ICT
Full text linkIl progetto OnToMap - Mappe di Comunità 3.0 nasce con l'obiettivo di sviluppare uno strumento capace di rispondere alle esigenze informative dei cittadini e di favorire il confronto tra questi e gli amministratori locali, creando uno spazio in cui le relazioni tra gli attori si articolino su una base cartografica e siano favorite dall'uniformità di linguaggio garantita dall'ontologia territoriale, nucleo della piattaforma. Il progetto si sviluppa a partire dalla costruzione di un'ontologia per la rappresentazione della conoscenza territoriale, realizzata attraverso l'individuazione dei concetti che compongono il territorio e l'identificazione delle relazioni semantiche che intercorrono tra essi. In questa prospettiva sono individuate le dimensioni costitutive del territorio, che tengono conto delle componenti ambientali, urbanistiche, culturali e sociali. Il principale risultato del progetto è l'applicazione web OnToMap per la gestione di mappe di comunità interattive. OnToMap è disponibile online, anche in versione mobile, e offre agli utenti internet un punto di vista integrato sul territorio, arricchibile secondo un modello di crowdsourcing e navigabile secondo criteri di ricerca semantici. La ricerca, tuttora in corso, si concentra su una sperimentazione dell'applicazione con lo scopo di produrre mappe partecipate su porzioni territoriali puntuali all'interno del contesto Torinese. In futuro OnToMap sarà arricchito, al fine di contribuire all'empowerment della cittadinanza, con nuove funzionalità; per esempio sarà possibile l'inserimento di nuovi dati da parte dell'utente, l'effettuazione di ricerche di informazioni per parola chiave, il supporto al ragionamento sui vincoli normativi che regolano il territorio e la creazione di forum di discussion
GroupCollaborate2: Interactive Community Mapping
Full text linkThis paper presents GroupCollaborate2, a prototype Participatory GIS for the management of 3D community maps which support the shared design of public policies by offering a virtual representation of the territory and by enabling the crowdsourcing of heterogeneous types of contributions, including documents, 3D models and comments, within focus group
OnToMap - Semantic Community Maps for knowledge sharing
Full text linkThis paper presents the information search features of OnToMap, a Participatory GIS supporting flexible information search, crowdsourcing and collaborative annotation of shared geographical information spaces. The advanced features offered by the application (e.g., semantic query expansion, presentation of information under different points of view, browsing of linked data) are based on a semantic knowledge representation layer that enables the exploitation of linguistic and domain knowledge to describe concepts, the integration of heterogeneous data, and the exploration of semantic relations among information types
Production of spatial representations through collaborative mapping. An experiment
Full text linkThis paper focuses on the theme of the spatial representation of cities and the territory, reflecting on the prospects for innovation in the expressive means that serve the study of the city. The described research concerns project "Mappe di Comunità 3.0" (http://ontomap.dyndns.org/), funded by the Fondazione CRT. The project focuses on the definition of a methodology that implements a synergistic exchange between institutional territorial knowledge and the knowledge of the citizens, achievable thanks to the mediation of communication provided by a semantic representation of territorial knowledge. That type of representation supports the description of data and of its properties in a unified language. Moreover, it enables the sharing of information on the Web by providing an integrated perspective on territorial dat
"Semantic Interpretation of Search Queries for Personalization"
Full text linkThis demo paper describes the semantic query interpretation model adopted in the OnToMap Participatory GIS and presents its benefits to information retrieval and personalized information presentation
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
Exploration of Cultural Heritage Information via Textual Search Queries
Full text linkSearching information in a Geographical Information System (GIS) usually imposes that users explore pre-compiled category catalogs and select the types of information they are looking for. Unfortunately, that approach is challenging because it forces people to adhere to a conceptualization of the information space that might be different from their own. In order to address this issue, we propose to support textual search as the basic interaction model, exploiting linguistic information, together with category exploration, for query interpretation and expansion. This paper describes our model and its adoption in the OnToMap Participatory GIS
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
