Abstract: Methods and systems for estimating a probability of re-sharing information include extracting keywords from a set of documents addressed to a user. The keywords from the set of documents are weighted according a metric for the user's interest in the keywords' respective source documents to create an interest model. A new document having one or more keywords is received. A likelihood that the user will re-share the new document is determined. The likelihood is based on the interest model and the one or more keywords present in the new document. The new document is automatically responded to based on the determined likelihood.

Abstract: In a case where supervised (learning) data is prepared and the case where test data is prepared, the data is recorded with time information attached to the data. The method includes clustering the learning data in a target class and clustering the test data in the target class. Then, the probability density for each of identified subclasses is calculated for each of time intervals having various time points and widths for the learning data, and is calculated for each of time intervals in the latest time period which have various widths, for the test data. Then, a ratio between a probability density obtained when learning is performed and a probability density obtained when testing is performed is obtained as a relative frequency in each of the time intervals for each of the subclasses. Input having a relative frequency that statistically and markedly increases is detected as an anomaly.

Abstract: A mobile terminal accesses global DNS server using a URI of a resource in an intranet. The global DNS server returns an IP address of an intranet domain access resolver. The mobile terminal connects to the intranet domain access resolver using the IP address and transmits a portion of the URI. The intranet domain access resolver encodes information received from the mobile terminal and generates a new URI and returns the new URI to the mobile terminal. The mobile terminal uses the new URI to access the intranet via a gateway based on an information item obtained by decoding the original URI.

Abstract: A technique for comprehensively acquiring calling-context information at a low cost. Call site IDs are held for each thread as a call history and used as context information. At the time of calling a method, the call history existing in a current frame is shifted left, and stacked in a new frame, with the call site ID of the call site put in the lower bits. At the time of returning from the method, the value of the original call history is returned by returning the frame. At the time of performing a virtual call, call history information is recorded into a call position profile table used to identify a method to be inlined at the time of performing JIT compiling, in addition to determined jump destination information and the number of calls.

Abstract: A method of estimating a viewing rate of a targeted message in a multicast messaging system is disclosed. A processor may be used to determine a first probability that at least one follower selects a received multicast message that accesses the targeted message using a processor. A second probability is calculated for the probability that the at least one follower accesses the targeted message from the selected multicast message. A third probability that the at least one follower views the targeted message is determined from the first probability and the second probability to determine the viewing rate of the targeted message. A message may be targeted for sending over the multicast messaging system at a time selected based on the determined third probability.

Abstract: The present invention provides a method for converting source code written in a dynamically typed language into target code written in a statically typed language. The method includes the step of generating in a storage device the target code from the source code, the step of generating the target code including storing in a buffer a signature of a function/method used by a caller in the source code. In this step, generation of an interface class is delayed to a time point immediately before execution of a part of the target code corresponding to the function/method call by the caller, the interface class being needed to generate the caller and serving as an interface in the statically typed language. The method also includes the step of generating in the storage device a consolidated interface class for all signatures stored in the buffer, and loading the generated consolidated interface class from the storage device.
