Abstract: A method for extracting key terms and associated key terms for use in text mining is provided. The method includes receiving unstructured text documents, such as emails over a customer service system. Term candidates are extracted based on identifying consecutive word strings satisfying a context independency threshold. Term candidates are weighted using mutual information to generate a list of weighted terms. The weighted terms are then recounted. Terms are associated based on Chi-square values. Associated terms can then be used for information retrieval. A user interface can be personalized with individual user profiles.

Abstract: This application discloses a computing system to implement a place and route tool to synthesize a clock tree in a layout design of an integrated circuit based on timing constraints for the integrated circuit. The computing system can select a portion of the clock tree to present in a schematic connectivity presentation based on a conformance of the portion of the clock tree to timing constraints for the clock tree. The computing system can compress the other portions of the clock tree into the compacted representation based on the selection of the portion of the clock tree. The compacted representation can retain a hierarchical connectivity of the other portions of the clock tree. The computing system can generate the schematic connectivity presentation of the clock tree that includes the selected portion of the clock tree coupled to at least one compacted representation of other portions of the clock tree.
