Semantic interaction for visual text analytics

Alex Endert, Patrick Fiaux, Chris North
2012 Proceedings of the 2012 ACM annual conference on Human Factors in Computing Systems - CHI '12  
In this paper, we present the opportunity for a new design space for visual analytic interaction, called semantic interaction, which seeks to enable analysts to spatially interact with such models directly  ...  within the visual metaphor using interactions that derive from their analytic process, such as searching, highlighting, annotating, and repositioning documents.  ...  Designing for Semantic Interaction In order for analysts to interact with information in a spatial metaphor, it must first be created.  ...

Towards interactive, intelligent, and integrated multimedia analytics

Jan Zahalka, Marcel Worring
2014 2014 IEEE Conference on Visual Analytics Science and Technology (VAST)  
The axis is composed of both exploration and search in a certain proportion which changes as the analyst progresses towards insight.  ...  In the model, the need for semantic navigation of the collection is emphasized and multimedia analytics tasks are placed on the explorationsearch axis.  ...  ACKNOWLEDGMENTS The authors thank Jack van Wijk for his insightful comments.  ...

Semantic annotations for digital investigations

Nikolaos Lagos, Stefania Castellani, Aaron Kaplan
2010 Proceedings of the third workshop on Exploiting semantic annotations in information retrieval - ESAIR '10  
In this paper, we describe how we believe semantic annotations can help in the provision of support for digital investigation activities for analysts searching for information in large document collections  ...  We describe here our current and future work on the construction of a system that provides tools and mechanisms for helping users better extract, navigate, select and store such information.  ...  In all these activities it is quite typical to have analysts searching large volumes of data looking for information supporting their line of inquires.  ...

Augmented Understanding and Automated Adaptation of Curation Rules [article]

Alireza Tabebordbar
2020 arXiv   pre-print
We propose: ~(1) a feature-based and automated technique for curating the raw data. ~(2) We propose an autonomic approach for adapting data curation rules. ~(3) We provide a solution to augment users in  ...  formulating their preferences while curating data in large scale information spaces. ~(4) We implement a set of APIs for automating the basic curation tasks, including Named Entity extraction, POS tags  ...  Usually, in an exploratory search, a user relies on text-based queries for formulating her preferences.  ...

Annotation Graphs: A Graph-Based Visualization for Meta-Analysis of Data Based on User-Authored Annotations

Jian Zhao, Michael Glueck, Simon Breslav, Fanny Chevalier, Azam Khan
2017 IEEE Transactions on Visualization and Computer Graphics  
We present a mixed-initiative approach to graph layout that integrates an analyst's manual manipulations with an automatic method based on similarity inferred from the annotation semantics.  ...  the annotation semantics from a different perspective.  ...  Moreover, these systems lack visual representations of the annotation space, i.e., they present annotation semantics in a text-based format, making it difficult for analysts to get an overview of the insights  ...

Real-time Social Media Analytics through Semantic Annotation and Linked Open Data

Diana Maynard, Mark A. Greenwood, Ian Roberts, George Windsor, Kalina Bontcheva
2015 Proceedings of the ACM Web Science Conference on ZZZ - WebSci '15  
This paper describes an open source framework for analysing large volume social media content, which comprises semantic annotation, Linked Open Data, semantic search, dynamic result aggregation, and information  ...  In particular, exploratory search and sense-making are supported through information visualisation interfaces, such as co-occurrence matrices, term clouds, treemaps, and choropleths.  ...  These are used both during semantic annotation and for semantic search and visualisations.  ...

2009 Lecture Notes in Computer Science  
Using combination of a content management system and a semantic knowledge base, the analyst can can enter new pieces information or interlink existing ones.  ...  The information is accessible either via semi-automatically authored textual analytical reports or semantic querying.  ...  This knowledge base allows the analysts to append and interlink information in a structured way. The knowledge base can be searched using a semantic query language.  ...

Semantic Interaction for Sensemaking: Inferring Analytical Reasoning for Model Steering

A. Endert, P. Fiaux, C. North
2012 IEEE Transactions on Visualization and Computer Graphics  
Spatially clustering data is one effective metaphor for users to explore similarity and relationships between information, adjusting the weighting of dimensions or characteristics of the dataset to observe  ...  We found that semantic interaction captures the analytical reasoning of the user through keyword weighting, and aids the user in co-creating a spatialization based on the user's reasoning and intuition  ...  Annotation is available for each document in the dataset. Through annotating a document, users can add "meta-information" to the document based on their domain expertise.  ...
