2019 arXiv   pre-print
Fast proliferation of robots in people's everyday lives during recent years calls for a profound examination of public consensus, which is the ultimate determinant of the future of this industry. This paper investigates text corpora, consisting of posts in Twitter, Google News, Bing News, and Kickstarter, over an 8 year period to quantify the public and media opinion about this emerging technology. Results demonstrate that the news platforms and the public take an overall positive position on

Besides, our evaluation reveals that the public and news media conceptualization of robotics has altered over the recent years. More specifically, a shift from the solely industrial-purposed machines, towards more social, assistive, and multi-purpose gadgets is visible.

Adaptive Faceted Ranking for Social Media Comments [chapter]

Elaheh Momeni, Simon Braendle, Eytan Adar
2015 Lecture Notes in Computer Science  
Online social media systems (such as YouTube or Reddit) provide commenting features to support augmentation of social objects (e.g. video clips or news articles). Unfortunately, many comments are not useful due to the varying intentions of the authors of comments as well as the perspectives of the readers. In this paper, we present, a framework and Web-based system for adaptive faceted ranking of social media comments, which enables users to explore different facets (e.g., subjectivity or

Based on an evaluation of the framework, we find that adaptive faceted ranking shows significant improvements over prevalent ranking methods, utilized by many platforms, with respect to the users' preferences.

Semi-automatic semantic moderation of web annotations

Elaheh Momeni
2012 Proceedings of the 21st international conference companion on World Wide Web - WWW '12 Companion  
Many social media portals are featuring annotation functionality in order to integrate the end users' knowledge with existing digital curation processes. This facilitates extending existing metadata about digital resources. However, due to various levels of annotators' expertise, the quality of annotations can vary from excellent to vague. The evaluation and moderation of annotations (be they troll, vague, or helpful) have not been sufficiently analyzed automatically. Available approaches

Despite this, we hypothesize that analyzing and exploiting both content and context dimensions of annotations may assist the automatic moderation process. In this research, we focus on leveraging the context and content features of social web annotations for semi-automatic semantic moderation. This paper describes the vision of our research, proposes an approach for semi-automatic semantic moderation, introduces an ongoing effort from which we collect data that can serve as a basis for evaluating our assumption, and report on lessons learned so far.

Online data journalism, including visualizations and other manifestations of data stories, has seen a recent surge of interest. User comments add a dynamic, social layer to interpretation, enabling users to learn from others' observations and social interact around news issues. We present the results of a qualitative study of commenting around visualizations published on a mainstream news outlet, The Economist's Graphic Detail blog. We find that surprisingly, only 42% of the comments discuss

Further, over one third of total comments provide direct critical feedback on the content of presented visualizations and text articles as well as on contextual aspects of the presentation. Our findings suggest using critical social feedback from comments in the design process, and motivate the development of more sophisticated commenting interfaces that distinguish comments by reference.

Augmenting Europeana content with linked data resources

Bernhard Haslhofer, Elaheh Momeni, Manuel Gay, Rainer Simon
2010 Proceedings of the 6th International Conference on Semantic Systems - I-SEMANTICS '10  
Annotations allow end users to augment digital items with information, which can then be exploited for search and retrieval. We are currently extending Europeana, a platform which links to millions of digital items in European institutions, with an annotation mechanism that exposes annotations as linked data and enriches newly created annotations with links to contextually relevant resources on the Web. In two demos we showcase how we integrated that kind of content augmentation into two

2011 Proceeding of the 11th annual international ACM/IEEE joint conference on Digital libraries - JCDL '11  
Historic maps are valuable scholarly resources that record information often retained by no other written source. With the YUMA Map Annotation Tool we want to facilitate collaborative annotation for scholars studying historic maps, and allow for semantic augmentation of annotations with structured, contextually relevant information retrieved from Linked Open Data sources. We believe that the integration of Web resource linkage into the scholarly annotation process is not only relevant for

In this paper, we introduce the COMPASS Experiment, an ongoing crowdsourcing effort in which we are collecting data that can serve as a basis for evaluating our assumption. We discuss the scope and setup of the experiment framework and report on lessons learned from the data collected so far.

2013 Proceedings of the 13th ACM/IEEE-CS joint conference on Digital libraries - JCDL '13  
Cultural institutions are increasingly opening up their repositories and contribute digital objects to social media platforms such as Flickr. In return they often receive user comments containing information that could be incorporated in their catalog records. Since judging the usefulness of a large number of user comments is a labor-intensive task, our aim is to provide automated support for filtering potentially useful social media comments on digital objects. In this paper, we discuss the

Then we present a machine-learning approach to automatically classify comments according to their usefulness. Our approach makes use of syntactic and semantic comment features and also considers user context. We present the results of an experiment we did on user comments received in six different Flickr Commons collections. They show that a few relatively straightforward features can be used to infer useful comments with up to 89% accuracy.

Scalable Daily Human Behavioral Pattern Mining from Multivariate Temporal Data

Reza Rawassizadeh, Elaheh Momeni, Chelsea Dobbins, Joobin Gharibshah, Michael Pazzani
2016 IEEE Transactions on Knowledge and Data Engineering  
This work introduces a set of scalable algorithms to identify patterns of human daily behaviors. These patterns are extracted from multivariate temporal data that have been collected from smartphones. We have exploited sensors that are available on these devices, and have identified frequent behavioral patterns with a temporal granularity, which has been inspired by the way individuals segment time into events. These patterns are helpful to both end-users and third parties who provide services

This scalability makes analysis on resource constrained and small devices such as smartwatches feasible. Traditional data analysis systems are usually operated in a remote system outside the device. This is largely due to the lack of scalability originating from software and hardware restrictions of mobile/wearable devices. By analyzing the data on the device, the user has the control over the data, i.e. privacy, and the network costs will also be removed.

Scalable Mining of Daily Behavioral Patterns in Context Sensing Life-Log Data [article]

Reza Rawassizadeh and Elaheh Momeni and Prajna Shetty
2015 arXiv   pre-print
Despite the advent of wearable devices and the proliferation of smartphones, there still is no ideal platform that can continuously sense and precisely collect all available contextual information. Ideally, mobile sensing data collection approaches should deal with uncertainty and data loss originating from software and hardware restrictions. We have conducted life logging data collection experiments from 35 users and created a rich dataset (9.26 million records) to represent the real-world

Our work benefits from combinations of sensors available on a device and identifies behavioral patterns with a temporal granularity similar to human time perception. Employing a combination of sensors rather than focusing on only one sensor can handle uncertainty by neglecting sensor data that is not available and focusing instead on available data. Moreover, by experimenting on two real, large datasets, we demonstrate that using a sliding window significantly improves the scalability of our algorithms, which can be used by applications for small devices, such as smartphones and wearables.
