  • We present a general framework for automatically extracting social networks and biographical facts from conversational speech. Our approach relies on fusing the output produced by multiple information extraction modules, including entity recognition and detection, relation detection, and event detection modules. We describe the specific features and algorithmic refinements effective for conversational speech.

  • We present a method for extracting social networks from literature, namely, nineteenth-century British novels and serials. We derive the networks from dialogue interactions, and thus our method depends on the ability to determine when two characters are in conversation. Our approach involves character name chunking, quoted speech attribution and conversation detection given the set of quotes. We extract features from the social networks and examine their correlation with one another, as well as with metadata such as the novel’s setting. ...

  • In my thesis, I propose to build a system that would enable extraction of social interactions from texts. To date I have defined a comprehensive set of social events and built a preliminary system that extracts social events from news articles. I plan to improve the performance of my current system by incorporating semantic information. Using domain adaptation techniques, I propose to apply my system to a wide range of genres.

  • Sociolinguists have long argued that social context influences language use in all manner of ways, resulting in lects 1 . This paper explores a text classification problem we will call lect modeling, an example of what has been termed computational sociolinguistics. In particular, we use machine learning techniques to identify social power relationships between members of a social network, based purely on the content of their interpersonal communication.

  • This paper proposes a sentiment analysis technique for Thai customers’ reviews. The proposed technique is based on the integration of Thai word extraction and sentiment analysis techniques for mining Thai customers’ opinions. Before the proposed technique is described in more detail, the segmentation problems of the Thai language are first discussed in the next section to clarify the problem.

  • We measure the reliable transport of event features from source nodes to the sink in terms of the number of received data packets. Regardless of any application-specific metric that may actually be used, the number of received data packets is closely related to the amount of information acquired by the sink for the detection and extraction of event features. Hence, this serves as a simple but adequate event reliability measure at the transport level.
