InactiveUS6845499B2Developing software applications have been substantially reduced or eliminatedShort development cycleSoftware designSpecific program execution arrangementsRequest - actionSoftware engineering
An XML-based framework (30) for developing software applications (12) includes a document manager (32) to manage activities relating to one or more XML-based data documents (34) associated with an application (12), each data document (34) modeling data associated with the application (12) and representing relationships between the data document (34) and one or more other data documents (34). The framework (30) includes a rules manager (36) to manage rules (38) specifying logic for handling notifications associated with XML-based action documents (34) received at the application (12), the notifications requesting actions involving data documents (34). The framework (30) also includes an operations manager (40) to manage the execution of transactions involving data documents (34) based on operations (42) defined for the application (12) during its development. The framework (30) provides a generic XML-based transaction engine, the application (12) being one of a plurality of distributed applications (12) each being an instance of the generic transaction engine. An electronic marketplace with a distributed transaction layer may include such a plurality of distributed applications (12), where the applications (12) interact with one another using the distributed transaction layer (14) to conduct electronic commerce within the marketplace.

InactiveCN102831234AAccurate grasp of interestAccurate and personalized news recommendationSpecial data processing applicationsPre treatmentTopic model
The invention discloses a personalized news recommendation device and method based on news content and theme feature. The recommendation device is equipped with seven modules, namely a news capturing module, a pre-treatment module, a theme model training module, a theme model predicting module, a user model building module, a news recommendation module and a recommendation treatment module. The recommendation method comprises the following steps: building an personalized user model with the theme model and a relevant named entity noun sequence to express the interest preference of the user reading news, and calculating weight and converting the theme feature vector of users so as to reduce the influence of hot themes and single news content on the user interest, thereby effectively overcoming the defects of concentrated user interest and insufficient diversity of recommendation results. In a recommendation output stage, an initial recommendation news list is treated, a theme grouping process based on the personalized user model is added on the basis of currently repeating data deleting and redundancy filtering, and news texts are reordered again according to the aging weight so as to recommend the accurate, diversified and novel personalized news.
