The nature of the enterprise and the way people work is changing rapidly. The enabling power and competitive advantage of new social and participative technologies will benefit those that recognize the way work is changing. Web 2.0, the “second phase” of the Web, is the foundation of a new and improved Enterprise 2.0. Enterprise 2.0 provides, through a web of interconnected applications, servic...

Customers in electronic commerce translate available information into buying decisions based on needs and behavioural tendencies. For this purpose, shopping sites provide detailed information on products and services ranging from simple figures (e.g., dimensions) to textual descriptions, user-generated reviews and visual images. All of the aforementioned sources of information may have a substa...

The purpose of this study is to examine the implications (user benefits and costs) of user generated content posted by users on Facebook to individual users. Although motivations to use social networking sites are widely researched and published, studies on implications of information on social networking sites is sparse. Hence, this study addresses this gap by an interpretive analysis of user ...

Enhancing local communities is seen as an enrichment of people’s life by providing additional possibilities for the building of relationships and identities. The question is how to improve these local social ties and how to promote interaction among people in local communities. Within this paper we will address this question based on a case study, where a local community is enhanced by an IPTV ...

With a boom in the internet, the social media text had been increasing day by day and the user generated content (such as tweets and blogs) in Indian languages are written using Roman script due to various socio-cultural and technological reasons. A majority of these posts are multilingual in nature and many involve code mixing where lexical items and grammatical features from two languages app...

In the audiovisual domain tagging games are explored as a method to collect user-generated metadata. For example, the Netherlands Institute for Sound and Vision deployed the video labelling game Waisda? to collect user tags for videos from their collection. These tags are potentially useful to improve the access to the content within the videos. However, the uncontrolled and often incomplete ta...

Mobile phone crowdsourcing is a powerful tool for many types of distributed sensing problems. However, a central issue with this type of system is that it relies on user contributed data, which may be sparse or erroneous. This paper describes our experiences developing a mobile phone crowdsourcing app, Kpark, for monitoring parking availability on a university campus. Our system combines multip...

This paper describes an algorithm for discovery of convoys in database with proximity log. Traditionally, discovery of convoys covers trajectories databases. This paper presents a model for context-aware browsing application based on the network proximity. Our model uses mobile phone as proximity sensor and proximity data replaces location information. As per our concept, any existing or even e...

Squiggle is a template-based glyph recognizer in the lineage of “$1 Recognizer”[1] and “Protractor”[2]. It seeks a good fit linear affine mapping between the input and template glyphs which are represented as a list of milestone points along the glyph path. The algorithm can recognize input glyphs invariant of rotation, scaling, skew, and reflection symmetries. In practice the algorithm is fast...

In recent years, the amount of user-generated opinionated texts (e.g., reviews, user comments) continues to grow at a rapid speed: featured news stories on a major event easily attract thousands of user comments on a popular online News service. How to consume subjective information of this volume becomes an interesting and important research question. In contrast to previous work on review ana...
