Abstract: A method for recommending semantic annotations on a main document and sub documents is provided. The method includes: extracting a keyword of the main document; extracting a or a set of keyword of each sub document; and generating a or a set of keyword similarity of each of the sub documents based on a degree of similarity between the keyword of the main document and the keyword of each of the sub documents. The method also includes: obtaining a plurality of words appeared on each of the sub documents and calculating a frequency of each of the words; generating a semantic capacity of each of the sub documents according to the frequencies; grouping the main document and at least one of the sub documents into a semantic document set based on the semantic capacities and the keyword similarities; and annotating the main document according to the semantic document set.

Abstract: A web application execution method, for a client to execute a web application on a remote server is provided. A connection status between the client and the remote server is monitored. If the connection is established, an online learning process is performed to monitor the handshakes between the client and the server, thereby constructing a virtual server. If the connection is disconnected, an offline service is activated, allowing the client to execute the web application through the virtual server. If the connection is reestablished after being disconnected, a synchronization process is performed to synchronize state machines within the virtual server and the server.
