- Abstract
- We present CopeOpi, an opinion-analysis system, which extracts from the Web opinions about specific targets, summarizes the polarity and strength of these opinions, and tracks opinion variations over time. Objects that yield similar opinion tendencies over a certain time period may be correlated due to the latent causal events. CopeOpi discovers relationships among objects based on their opinion-tracking plots and collocations. Event bursts are detected from the tracking plots, and the strength of opinion relationships is determined by the coverage of these plots. To evaluate opinion mining, we use the NTCIR corpus annotated with opinion information at sentence and document levels. CopeOpi achieves sentence- and document-level f-measures of 62% and 74%. For relationship discovery, we collected 1.3M economics-related documents from 93 Web sources over 22 months, and analyzed collocation-based, opinion-based, and hybrid models. We consider as correlated company pairs that demonstrate similar stock-price variations, and selected these as the gold standard for evaluation. Results show that opinion-based and collocation-based models complement each other, and that integrated models perform the best. The top 25, 50, and 100 pairs discovered achieve precision rates of 1, 0.92, and 0.79, respectively.

- Rez. in: JASIST 58(2007) no.1, S.150-151 (L. Westbrook): "The purpose of this volume is to bring together various analyses by international scholars of the social and cultural impact of information technology on individuals and societies (preface, n.p.). It grew from the First International Conference on Human Perspectives in the Internet Society held in Cadiz, Spain, in 2004. The editors and contributors have addressed an impressive array of significant issues with rigorous research and insightful analysis although the resulting volume does suffer from the usual unevenness in depth and content that affects books based on conference proceedings. Although the $256 price is prohibitive for many individual scholars, the effort to obtain a library edition for perusal regarding particular areas of interest is likely to prove worthwhile. Unlike many international conferences that are able to attract scholars from only a handful of nations, this genuinely diverse conference included research conducted in Australia, Beijing, Canada, Croatia, the Czech Republic, England, Fiji, Germany, Greece, Iran, Ireland, Israel, Italy, Japan, Jordan, Malaysia, Norway, Russia, Scotland, South Africa, Sweden, Taiwan, and the United States. The expense of a conference format and governmental travel restrictions may have precluded greater inclusion of the work being done to develop information technology for use in nonindustrialized nations in support of economic, social justice, and political movements. Although the cultural variants among these nations preclude direct cross-cultural comparisons, many papers carefully provide sufficient background information to make basic conceptual transfers possible. A great strength of the work is the unusual combination of academic disciplines that contributes substantially to the depth of many individual papers, particularly when they are read within the larger context of the entire volume. Although complete professional affiliations are not universally available, the authors who did name their affiliation come from widely divergent disciplines including accounting, business administration, architecture, business computing, communication, computing, economics, educational technology, environmental management, experimental psychology, gender research in computer science, geography, human work sciences, humanistic informatics, industrial engineering, information management, informatics in transport and telecommunications, information science, information technology, management, mathematics, organizational behavior, pedagogy, psychology, telemedicine, and women's education. This is all to the good, but the lack of representation from departments of women's studies, gender studies, and library studies certainly limits the breadth and depth of the perspectives provided.
