The field of software metrics is constantly changing and metrics extraction tools have to be updated frequently to handle these changes. This paper details the use of an intermediate relation set to decouple code parsing from metrics analysis. Parsers simply generate a set of intuitive relations, which a separate analyzer uses as input to compute arbitrary metrics. Then, new metrics simply have...

This paper presents some statistical observations relevant to Japanese keyphrase extraction, as well as the details of the implementation of a keyphrase extraction algorithm (called Extractor) for Japanese documents. Parts of the algorithm include an efficient method of extracting the keyphrase candidates, a way to pinpoint the most probable keyphrases using contextual information, a technique ...

Extracting binary strings from real-valued biometric templates is a fundamental step in template compression and protection systems, such as fuzzy commitment, fuzzy extractor, secure sketch, and helper data systems. Quantization and coding is the straightforward way to extract binary representations from arbitrary real-valued biometric modalities. In this paper, we propose a pairwise adaptive p...

Electronic Music Distribution (EMD) is in demand of robust, automatically extracted music descriptors. We introduce a timbral similarity measures for comparing music titles. This measure is based on a Gaussian model of cepstrum coefficients. We describe the timbre extractor and the corresponding timbral similarity relation. We describe experiments in assessing the quality of the similarity rela...

This paper describes a word alignment system (TREQ-AL), which uses the lexicon extracted with a translation equivalence extractor (TREQ) from a training corpus, including the text of test. The improvement methods applied since the previous version TREQ-AL are one of the paper’s focus, as well as the recalled types of the system.

Fuzzy extractor is a powerful but theoretical tool to extract uniform strings from discrete noisy data. Before it can be used in practice, many concerns need to be addressed in advance, such as making the extracted strings renewable and dealing with continuous noisy data. We propose a primitive fuzzy embedder as a practical replacement for fuzzy extractor. Fuzzy embedder naturally supports rene...

A CMOS rail-to-rail comparator operating at low-voltage supply by using a conventional fabrication process is proposed. Based on the comparator, an analog rank-order extractor with winner-take-all capability is presented. An experimental chip was fabricated using 0.5 m CMOS technology. Measured results at 1–V supply voltage show a comparator response time of 4 s for 10-mV precision and that the...
