System and method for aggregating, distributing, and monetizing the collective wisdom of consumers

A networked system collects, aggregates, and distributes the collective wisdom of consumers. An aggregation module obtains, from each of a plurality of reviewing consumers: i) a file comprising a motion video clip depicting a video product review of a product; and ii) the reviewing consumer's indication of at least one categorization data element identifying the product. A motion video clip database stores each motion video clip. A search database stores, for each motion video clip, the at least one product categorization data element identifying the product depicted in the motion video clip. A search module receives a search term from a searching consumer and identifies a selected group of video product reviews. The selected group of video product reviews comprises those video product reviews that are a relevant video product review. A relevant video product review comprises a video product review that is associated with a product categorization data element corresponding to the search term. A monetization module debits a first predetermined value from a merchant's account upon each occurrence of a target event. The target event may comprise the searching consumer initiating interaction with a link associated with web content comprising additional information about the product depicted in the video product review.

Text orientation analysis method and product review orientation discriminator on basis of same

The invention discloses a text orientation analysis method which comprises the following steps of: preprocessing a review text; identifying a dependency relation structure of the Chinese syntax; calculating content polarity values of sentiment words; completing two-tuples extraction of evaluated objects and evaluation words and determining a slave relation between the evaluated objects; weighting and summing orientation values of the sentiment words to obtain an orientation value of a sentence so as to implement discrimination on orientation of a sentence level; discriminating appraising orientation of sentiment in the review by positive and negative polarity values of the sentence level; and according to the size of a polarity absolute value, discriminating intensity of appraising sentiment in the review. A product review orientation discriminator comprises an acquisition module, a preprocessing module, a syntactic analysis module, a sentiment calculating engine, a two-tuples mining engine, a content controller and a sentiment discriminator. According to the invention, a combined sentiment dictionary is combined and a domain ontology is added into text orientation analysis; accuracy of polarity calculation of the sentiment words and (the evaluated objects and the evaluation words) two-tuples extraction is improved; and orientation analysis on product reviews in a forum is implemented.

CRFs (conditional random fields) and SVM (support vector machine) based method for extracting fine-granularity sentiment elements in product reviews

The invention discloses a CRFs (conditional random fields) and SVM (support vector machine) based method for extracting fine-granularity sentiment elements in product reviews. The method comprises the steps as follows: a, a CRFs model is adopted, review language characteristics are taken as sequences, then position labelling is performed on review languages according to the sequences, corresponding rules are adopted to perform stratified filtering on error labels, and extraction for sentiment subjects and sentiment words is finished; and b, an SVM model is adopted to perform sentiment orientation analysis on word pairs according to the extracted sentiment subjects and sentiment words as well as introduced sentence structure features. According to the invention, the sentiment subjects and the sentiment words in review sentences are extracted together, further, sentiment classification accuracy in the sentiment orientation analysis is improved, so that the sentiment element extraction and sentiment judgment are improved, and F value is up to 76.3%; due to introduction of word meaning codes, the generalization ability and the robustness of a system are improved by virtue of the word meaning codes, and the accurate rate and recall rate of review result analysis are greatly improved.
