Large-scale taxonomy induction using entity and word embeddings
No full textTaxonomies are an important ingredient of knowledge organization, and serve as a backbone for more sophisticated knowledge representations in intelligent systems, such as formal ontologies. However, building taxonomies manually is a costly endeavor, and hence, automatic methods for taxonomy induction are a good alternative to build large-scale taxonomies. In this paper, we propose TIEmb, an approach for automatic unsupervised class subsumption axiom extraction from knowledge bases using entity and text embeddings. We apply the approach on the WebIsA database, a database of subsumption relations extracted from the large portion of the World Wide Web, to extract class hierarchies in the Person and Place domain
Data Semantics: \u3cem\u3eWhat, Where, and How?\u3c/em\u3e
No full textAt the panel held during the last session of the DS-6 conference, four panelists -- Leo Mark, Robert Meersman, Sham Navathe, and Arnon Rosenthal -- addressed the key questions related to the topic of the conference, related their perspectives to what was presented and discussed at the conference, and suggested research issues in data semantics that they would like to see addressed in the future. The panel was organized, introduced, and moderated by the author. Several conference participants also presented short position statements during the panel. This chapter summarizes the lively and often insightful panel discussion, along with additional thoughts of the author/moderator
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
Tracking over Collaborative Business Processes
No full textWorkflow monitoring is a routine function of a workflow manag-ement system for tracking the progress of running workflow instances. To keep participating organisations as autonomous entities in an inter-organisational business collaboration environment, however, it brings challenges in generating workflow tracking structures and manipulating instance correspondences between different participating organisations. Aiming to tackle these problems, this paper proposed a matrix based framework on the basis of our relative workflow model. This framework enables a participating organisation to derive tracking structures over its relative workflows and the involved relevant workflows of its partner organisations, and to perform workflow tracking with the generated tracking structures
Computing for the Human Experience: Semantics-Empowered Sensors, Services, and Social Computing on the Ubiquitous Web
Get PDFPeople are on the verge of an era in which the human experience can be enriched in ways they couldn\u27t have imagined two decades ago. Rather than depending on a single technology, people progressed with several whose semantics-empowered convergence and integration will enable us to capture, understand, and reapply human knowledge and intellect. Such capabilities will consequently elevate our technological ability to deal with the abstractions, concepts, and actions that characterize human experiences. This will herald computing for human experience (CHE). The CHE vision is built on a suite of technologies that serves, assists, and cooperates with humans to nondestructively and unobtrusively complement and enrich normal activities, with minimal explicit concern or effort on the humans\u27 part. CHE will anticipate when to gather and apply relevant knowledge and intelligence. It will enable human experiences that are intertwined with the physical, conceptual, and experiential worlds (emotions, sentiments, and so on), rather than immerse humans in cyber worlds for a specific task. Instead of focusing on humans interacting with a technology or system, CHE will feature technology-rich human surroundings that often initiate interactions. Interaction will be more sophisticated and seamless compared to today\u27s precursors such as automotive accident-avoidance systems. Many components of and ideas associated with the CHE vision have been around for a while. Here, the author discuss some of the most important tipping points that he believe will make CHE a reality within a decade
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
