Abstract: A method for categorizing a use scenario of a product is disclosed. The method includes extracting, from a text describing the use scenario of the product, at least one feature tuple capable of characterizing the use scenario and performing a latent semantic association analysis on the at least one feature tuple to obtain a latent topic sequence for the use scenario. Further, the method includes determining a product scenario category to which the use scenario belongs according to the latent topic sequence for the use scenario. Additionally, a corresponding apparatus is also disclosed.

Abstract: Visualizing content change of a data collection over time. A topic may be split into multiple linear, non-overlapping sub-topics along a timeline by satisfying a diverse set of semantic, temporal, and visualization constraints simultaneously. For each derived sub-topic, a set of representative keywords may be automatically selected to summarize the main content of the sub-topic.

Abstract: Comparing document contents is provided. An ontological concept is extracted from a text snippet of a corpus document. One or more feature vectors are constructed that include associative information that describes an ontology that includes the focused concept. A topic model is trained using the one or more feature vectors. First and second topic sets are respectively extracted from first and second documents using the topic model. One or more topics from the first topic set are matched, using the topic model, with one or more topics from the second topic set to construct a matched topic set. Semantic analyses are respectively performed on first and second text snippet sets, wherein the first and second text snippet sets are chosen based, at least in part, on the matched topic set. Text snippets are matched based, at least in part, on the first and second semantic analyses.

Abstract: The invention provides a method and system for visualization of a data set, the method comprises: dividing the data set into a plurality of information layers based on different information dimensions; and visually processing the plurality of information layers based on different information dimensions, respectively, in order to present respective views of the plurality of information layers. In the present invention, by visualizing the data set through presenting different overviews of the data set from different information dimensions, respectively, the presentation of comprehensive information of the data set to a data set analyst is ensured while distortion of presented contents as well as visual clutter are prevented.

Abstract: A method, apparatus for touch screen display process, and a browser are provided in the present disclosure. The method comprises: identifying Web elements used for Web interaction displayed on a touch screen; in response to a first action of a user on the touch screen, displaying the Web element pointed by the first action with enlargement; and in response to a second action of the user on the touch screen, triggering a Web interaction operation corresponding to the Web element pointed by the first action. According to the above technical solution, by displaying the Web element pointed by the first action of the user with enlargement, the user can preview the Web element that he actually selects, and a Web interaction is triggered only if it is determined that the Web element desired by the user has been correctly selected. Therefore, precise click can be realized.

Abstract: A method and an apparatus for identifying sub-graphs similar to a sample sub-graph from a network, in particular for identifying similar community structures from a network, are disclosed. Specifically, when a sample sub-graph is a community structure, it usually contains a plurality of nodes densely associated with each other. The method proposes first screening the network via key nodes of community structures so as to find sub-graph candidates that are potentially similar to the sample sub-graph, then strictly comparing the sub-graph candidates with the sample sub-graph to find similar sub-graphs of the sample sub-graph.

Abstract: A method and system of producing a visual text summarization. According to the method, a plurality of topics may be extracted from a collection of text documents, where each of the topics comprises a distribution of topic keywords. An importance ranking for each of the topics may be determined, and an importance ranking for each of the topic keywords of a topic may also be determined. A graph may be displayed having a plurality of stacked layers representing a group of topics selected from the plurality of topics based on the importance ranking of the topics. A keyword cloud within each layer of the graph may also be displayed, where the one keyword cloud is a group of topic keywords selected from the extracted topic keywords based on the importance ranking of the extracted topic keywords.

Abstract: Methods and apparatus are provided for intelligent exploratory visualization and analysis. A semantics-based client-server application architecture is provided that enables interactive visualization and analysis applications over the web. From the client perspective, user activities are observed and the client determines if a sequence of user activities comprises one or more predefined semantics-based user actions. Semantics-based action descriptor are then sent to the server, optionally with any related parameters, and a response is then received from the server. From the server perspective, one or more semantics-based action descriptors are received from the client with an action type selected from a predefined set of types, wherein the semantics-based action descriptors are based on a sequence of activities of a user. The server processes the semantics-based action descriptors and sends a response to the client in response to the one or more semantics-based action descriptors.
