15:00-15:30 Extracting Semantic Relations for Mining of Social Data (abstract)
Shinichi Nagano, Masumi Inaba, and Takahiro Kawamura

This paper proposes a novel method that extracts semantic relations from social data in order to acquire ontologies that are used for mining social data. A set of nouns are iteratively extracted from documents in a bootstrapping manner, and then a semantic relation between a noun pair is identified by a clustering procedure. The main feature is exploitation of the co-occurrence of a verb and a noun in a sentence, considering that a verb plays an important role in expressing the meaning of a sentence. The paper presents a preliminary study to clarify problems in order to achieve practical performance.

short paper
15:30-16:00 End-User Programming and the Advent of Sharable, Social Machines (abstract)
Evan Patton, Dominic Difranzo, and Deborah L. McGuinness

We present a web application that allows users to reuse RDF content from existing sites (e.g., DBpedia), extract data from the social networks like Facebook and Twitter, and manipulate those data through JavaScript applets. Users combine these applets for processing and visualizing data in a Graphical User Interface, similar to scientific work- flow systems. Unlike workflow systems, users are encouraged to view and interact with data interactively and manipulate it in an exploratory fashion. User-constructed applet pipelines are encoded as RDF files, allowing publication and collaboration, thus taking a critical step forward in moving to an end-user programmable social machine environment.

16:30-17:00 Do Not Feel The Trolls (abstract)
Erik Cambria, Praphul Chandra, Avinash Sharma, and Amir Hussain

The passage from a read-only to a read-write Web gave people the possibility to freely interact, share and collaborate through social networks, online communities, blogs, wikis and other online collaborative media. The democracy of the Web is what made it so popular in the past decades but such a high degree of freedom of expression also gave birth to negative side effects – the so called ‘dark side’ of the Web. An example of this is trolling i.e. the exploitation of the anonymity of the Web to post inflammatory and outrageous messages directed to one specific person or community to provoke them into a desired emotional response. Online community masters usually warn users against trolls with messages such as DNFTT (Do Not Feed The Trolls) but so far this has not been enough to stop trolls trolling. The aim of this work is to use Sentic Computing, a new paradigm for the affective analysis of natural language text, to detect trolls and hence prevent web-users from being emotionally hurt by malicious posts.

17:00-17:30 Mapping Tweets to Conference Talks: A Goldmine for Semantics (abstract)
Milan Stankovic, Matthew Rowe, and Philippe Laublet

The short message service Twitter has gained significant popularity and uptake among participants of conferences and organized events as a backchannel for intra-event communication. Information that is exchanged explicitly through such tweets, or that is implicitly present in them, remains mostly hidden and undecipherable to machines. In this paper we propose a framework for extracting valuable information from conference tweets, enabling its publication as Linked Data. We introduce the concept of mapping tweets with the talks and subevents that they refer to, in doing so gaining access to additional information about the users, talks and dynamics of the event. We present preliminary results of our work towards tweet-talk mappings and motivate our current and future work by giving several use cases for such extracted data.

17:30-18:00 Computing FOAF Co-reference Relations with Rules and Machine Learning (abstract)
Jennifer Sleeman, and Tim Finin

The friend of a friend (FOAF) vocabulary is widely used on the Web to describe ’agents’ (people, groups and organizations) and their properties. Since FOAF does not require unique ID for agents, it is not clear when two FOAF instances should be linked as co-referent, i.e., denote the same entity in the world. One approach is to use logical constraints such as the presence of inverse functional properties as evidence that two individuals are the same. Another applies heuristics based on the string similarity of values of FOAF properties such as name and school as evidence for or against co-reference. Performance is limited, however, by many factors: non-semantic string matching, noise, changes in the world, and the lack of more sophisticated graph analytics. We describe a prototype system that takes a set of FOAF agents and identifies subsets that are believed to be co-referent. The system uses logical constraints (e.g., IFPs), strong heuristics (e.g., FOAF agents described in the same file are not co-referent), and an SVM generated classifier. We present initial results using data collected from Swoogle and other sources and describe plans for additional analysis.

Aim and scope

The 3rd international workshop Social Data on the Web (SDoW2010) co-located with the 9th International Semantic Web Conference (ISWC2010) aims to bring together researchers, developers and practitioners involved in semantically-enhancing social media websites, as well as academics researching more formal aspect of these interactions between the Semantic Web and Social Web.

It is now widely agreed that the Semantic Web and the Social Web can benefit from each other. On the one hand, the speed at which data is being created on the Social Web is growing at exponential rate, as it offers users a variety of applications for rapidly publishing and disseminating information to a community of interest: blogs, wikis, microblogging, status notification, etc. On the other hand, the Semantic Web plays a crucial role in the management of all this networked knowledge, providing new ways to share and co-operate on the Web using formal semantics. However, while both can be efficiently combined to take into account the social aspect and the semantics of this data, there are still a variety of important issues and research questions that must be considered regarding data that arises from social interactions, such as scalability, reasoning, privacy, context-awarness, security, etc.

Following the success of SDoW2008 and SDoW2009, this workshop aims to discuss techniques, methods and applications that are appearing and that are required to manage the data from the Social Web using semantic technologies, taking into account social relations, information overload, aggregations and summaries, trust and privacy, and other related research topics.

Topics of Interest

We encourage contributions which will describe research proposals or implementations that deal with (but are not limited to) the following topics of interest:

  • Applications and tools using Social Semantic Web technologies
  • Creating RDF-based knowledge using social media services
  • Data Portability and Social Network Portability
  • Emerging semantic platforms for the Social Web
  • Enriching Social Web with semantic data - RDFa, microformats and other approaches
  • Linked Data on the Social Web - providing linked data from social media sites
  • Mining and analysis of Social Data
  • Ontologies for the Social Web - developing, using and extending lightweight ontologies for social media sites
  • Querying and mining social semantic data
