Taming the logs - Vocabularies for semantic security analysis

Semantic Outlier Analysis for Sessionizing Web Logs

As the web usage patterns from clients are getting more complex, simple sessionizations based on time and navigation-oriented heuristics have been restricted to exploit various kinds of rule discoverying methods. In this paper, we present semantic session reconstruction based on semantic outliers from web log data. Above all, web directory service such as Yahoo is applied to enrich semantics to...

Using query logs to establish vocabularies in distributed information retrieval

Users of search engines express their needs as queries, typically consisting of a small number of terms. The resulting search engine query logs are valuable resources that can be used to predict how people interact with the search system. In this paper, we introduce two novel applications of query logs, in the context of distributed information retrieval. First, we use query log terms to guide ...

Application of latent semantic analysis using different vocabularies

organic molecule, 11-cis retinal, a vitamin A derivative, readjusts its shape by changing a single bond on seeing light to form all-trans retinal. While this small change may not seem very significant, it makes a big difference for perception of light in human vision: this is the way by which the brain knows that a photon has landed on the eye. How? The retinal is embedded inside another molecu...

RDA Element Sets and RDA Value Vocabularies: Vocabularies for Resource Description in the Semantic Web

Considering the need for metadata standards suitable for the Semantic Web, this paper describes the RDA Element Sets and the RDA Value Vocabularies that were created from attributes and relationships defined in Resource Description and Access (RDA). First, we present the vocabularies included in RDA Element Sets: the vocabularies of classes, of properties and of properties unconstrained by FRBR...
