Improving relevance in a content pipeline via syntactic generalization

A number of content pipeline components employ web mining which needs SG to compare web search results. We describe how SG works in a number of components in the content pipeline including personalization and recommendation, and provide the evaluation results for eBay deployment. Content pipeline support is implemented as an open source contribution OpenNLP.Similarity and is available at https://github.com/bgalitsky/relevance-based-on-pars-trees.
