Over the past 5 years, a small group of cancer patients who stated their physicians had determined there were no additional available antineoplastic therapeutic options (including potential investigational strategies) were seen for a 'second opinion' in a cancer hospital-based oncology program and subsequently experienced what can reasonably be characterized as having achieved meaningful 'clini...

Automatic extraction of opinion holders and targets (together referred to as opinion entities) is an important subtask of sentiment analysis. In this work, we attempt to accurately extract opinion entities from Urdu newswire. Due to the lack of resources required for training role labelers and dependency parsers (as in English) for Urdu, a more robust approach based on (i) generating candidate ...

This is because of a lack of both (1) annotated data at the word level and (2) algorithms that can leverage syntactic information in a principled way. We address the first need by annotating articles from the information technology...

Feature selection is an important step in opinion mining, as customers express product opinions separately according to individual features.
