A semantic session analysis method partitioning Web usage logs is presented.Semantic W eb usage log preparation model enhances usage logs with semantic.The M arkov chain
mode1 based on ontology semantic measurement is used to identi.
ing which active session a request should belong to.The corn—
petitive method is applied to determine the end of the sessions.
Compared with other algorithms,more successfu1 sessions are additionally detected by semantic outlier analysis.
The task of clustering Web sessions is to group Web sessions based on similarity and consists of maximizing the intra-
group similarity while minimizing the inter-group similarity.
The first and foremost question needed to be considered in clustering
W b sessions is how to measure the similarity between Web
sessions.However.there are many shortcomings in traditiona1
measurements.This paper introduces a new method for measuring
similarities between Web pages that takes into account not only the
URL but also the viewing time of the visited web page.Yhen we
give a new method to measure the similarity of Web sessions using
sequence alignment and the similarity of W eb page access in detail
Experiments have proved that our method is valid and e幣cient.
Atmel’s AT91SAM7FP105 is a low pincount FingerChip processor based on the 32-bit ARM
RISC processor. It features a on-chip biometric engine performing enrollment verification and
identification, an internal record cache of up to 25 records and a secure command protocol over
USB, SPI, UART. This protocol enables an external host system or processor to control the onchip
bioengine functions, manipulate the record cache, and securely export record cache
records for external storage. Together with the FingerChip sensor device AT77C104B, it forms
an embedded, secured biometric turnkey solution.
