Keyword Extraction and Semantic Tag Prediction
Content on the web is often organized through user generated tags for intuitive search and retrieval. Such tags convey meta-information about the subject matter of the texts they represent. For this project, we applied machine learning (Bayesian co-occurrence, k-NN, SVM, NNS) to predict tags of StackExchange posts obtained from Kaggle: “Facebook Recruiting Keyword Extraction III.” Using our non...
متن کاملA Two-Level Learning Hierarchy of Concept Based Keyword Extraction for Tag Recommendations
Textual contents associated to resources are considered as sources of candidate tags to improve the performance of tag recommenders in social tagging systems. In this paper, we propose a twolevel learning hierarchy of a concept based keyword extraction method to filter the candidate tags and rank them based on their occurrences in concepts existing in the given resources. Incorporating user-cre...
متن کاملTwo-step TAG parsing revisited
Based on the work in (Poller, 1994) and a minor assumption about a normal form for TAGs, we present a highly simplified version of the twostep parsing approach for TAGs which allows for a much easier analysis of run-time and space complexity. It also snggests how restrictions on the grammars might result in improvements in run-time complexity. The main advantage of a two-step parsing system sho...
متن کاملA Case Report of a Giant Skin Tag
Skin tags are skin-colored, asymptomatic, pedunculated lesions located at the neck, axillae or groin. It affects any age, including infants. We report a 60-year-old Iranian woman with a giant pedunculated skin tag on the left thigh for 10 years. It measured 10 cm in length and 7 cm in width, distally.
متن کاملUnderstanding Tag Systems by Comparing Tag models
Since Holland (1993) introduced the concept of tags a number of tag models with intriguing and potentially very useful, properties have been advanced. However there is currently little understanding as to the exact mechanisms that produce these results. Specifically it is not know what (if any) are the necessary conditions for tag systems to produce high levels of cooperation in social dilemmas...
