    Identification of contexts associated with sentences is becoming increasingly necessary for developing intelligent information retrieval systems. This article describes a supervised learning mechanism employing a conditional random field (CRF) for context identification and sentence classification. Specifically, we focus on sentences in related work sections in research articles. Based on a generic rhetorical pattern, a framework for modelling the sequential flow in these sections is proposed. Adopting a generalization strategy, each of these sentences is transformed into a set of features, which forms our dataset. We distinguish between two kinds of features for each of these sentences viz., citation features and sentence features. While an overall accuracy of 96.51% is achieved by using a combination of both citation and sentence features, the use of sentence features alone yields an accuracy of 93.22%. The results also show F-Scores ranging from 0.99 to 0.90 for various classes indicating the robustness of our application.

  • Networking audio

    With the installation of the Music Department’s new SSL mixing console and the founding of the New Zealand Music Industry Centre (NZMiC), there are exciting new possibilities for sound production and performance at Otago, especially across digital networks. To what extent might a “distributed recording studio” be feasible, and what technical flies might await in the proverbial ointment? This talk will examine some of the capabilities of the KAREN research network for audio, discuss the possibility of using the Internet Network Time Protocol (NTP) or the Global Positioning System (GPS) to keep remote audio hardware clocks synchronised, consider the effects of network latency, and suggest some avenues for developing a software infrastructure for distributed audio work.
