Catia Pesquita, Valentina Ivanova, Steffen Lohmann, Patrick Lambrix
2018 Lecture Notes in Computer Science  
We then chart the design space of available methods for user studies in Semantic Web contexts.  ...  While a number of user interfaces for Semantic Web systems have become available in the past years, their evaluation and reporting often still suffer from weaknesses.  ...  The design space and protocol together constitute a framework for conducting and reporting on empirical user studies in Semantic Web contexts.  ...

Exploring Session Context using Distributed Representations of Queries and Reformulations

Bhaskar Mitra
2015 Proceedings of the 38th International ACM SIGIR Conference on Research and Development in Information Retrieval - SIGIR '15  
Our empirical study demonstrates that short-term (session) history context features based on these two representations improves the mean reciprocal rank (MRR) for the QAC ranking task by more than 10%  ...  In this paper, we study the distributed representation of queries learnt by deep neural network models, such as the Convolutional Latent Semantic Model, and show that they can be used to represent query  ...  Assumptions and limitations. We have based our empirical study on the supervised ranking framework proposed by Shokouhi [37] .  ...

and encourage users to actively detect and report semantic social engineering attacks against them.  ...  In an organisation that employs a human-as-a-security-sensor implementation, such as Cogni-Sense, an attack is considered to have been detected if at least one user has reported it.  ...  Benefiting from the complete implementation of the framework, we have conducted the first empirical experiment for utilising a HaaSS system in the context of semantic attack detection, across several more  ...

A Framework for Ontology Usage Analysis [chapter]

Jamshaid Ashraf
2012 Lecture Notes in Computer Science  
Such a study is very important to (a) make effective and efficient use of formalized knowledge (ontology) available on the web, (b) provide a usage-based feedback loop to the ontology maintenance process  ...  The Semantic Web (also known as the Web of Data) is growing rapidly and becoming a decentralized social and knowledge platform for publishing and sharing information.  ...  The theoretical exploration and development of the framework is divided into the following sub-stages: Construction of RDF dataset: In order to conduct an empirically grounded study, it is important  ...

Analyzing the Impact of Automated User Assistance Systems: A Systematic Review [article]

Murat Acar, Bedir Tekinerdogan
2020 arXiv   pre-print
Context: User assistance is generally defined as the guided assistance to a user of a software system in order to help accomplish tasks and enhance user experience.  ...  Method: A systematic literature review is conducted by a multiphase study selection process using the published literature since 2002.  ...  Finally, the information extraction scheme we used to characterize the study context and study findings can be used to guide the activities of designing and reporting future empirical studies of AUA.  ...
