20120239668 | EXTRACTION AND GROUPING OF FEATURE WORDS - Various embodiments of systems and methods for extraction and grouping of feature words are described herein. Feature words are obtained from a first corpus of text bodies comprising a plurality of reviews. A second corpus is created using a combination of the obtained feature words, verbs and adjectives from the first corpus. The second corpus comprises filtered reviews and each of the filtered reviews pertains to a review. Topics are preliminarily assigned for words in the filtered reviews of the second corpus. For each of the feature words in the second corpus, a topic count is determined for every preliminarily assigned topic. After determining the topic count, one or more of the topics are finally assigned to the feature words based on a topic count value. At least one topic is presented as a group of the feature words for which the at least one topic is assigned based on the topic count value. | 09-20-2012 |
20130224713 | ENHANCING KNOWLEDGE BASES USING RICH SOCIAL MEDIA - Methods and arrangements for developing knowledge bases from social media. A question is obtained from social media. Social media are consulted, and a legitimacy of the question is ascertained. All the answers to the question are harvested from the social media including the rich media that is associated with these answers, and the question is filtered out if determined not to be legitimate. | 08-29-2013 |

20120175269 | ADVANCED AROMATIC AMINE HETEROCYCLIC CATALYSTS FOR CARBON DIOXIDE REDUCTION - Methods and systems for electrochemical reduction of carbon dioxide using advanced aromatic amine heterocyclic catalysts are disclosed. A method for electrochemical reduction of carbon dioxide may include, but is not limited to, steps (A) to (C). Step (A) may introduce water to a first compartment of an electrochemical cell. Said first compartment may include an anode. Step (B) may introduce carbon dioxide to a second compartment of said electrochemical cell. Said second compartment may include a solution of an electrolyte, a catalyst, and a cathode. Said catalyst may include at least two aromatic amine heterocycles that are at least one of (a) fused or (b) configured to become electronically conjugated upon one electron reduction. Step (C) may apply an electrical potential between said anode and said cathode in said electrochemical cell sufficient for said cathode to reduce said carbon dioxide to a product mixture. | 07-12-2012 |
20130008800 | CARBON DIOXIDE CAPTURE AND CONVERSION TO ORGANIC PRODUCTS - Methods and systems for capture of carbon dioxide and electrochemical conversion of the captured carbon dioxide to organic products are disclosed. A method may include, but is not limited to, steps (A) to (C). Step (A) may introduce a solvent to a first compartment of an electrochemical cell. Step (B) may capture carbon dioxide with at least one of guanidine, a guanidine derivative, pyrimidine, or a pyrimidine derivative to form a carbamic zwitterion. Step (C) may apply an electrical potential between an anode and a cathode sufficient for the cathode to reduce the carbamic zwitterion to a product mixture. | 01-10-2013 |
