Relational DBMSs continue to dominate the database market, and inference problem on external schema of relational DBMS’s is still an important issue in terms of data privacy. Especially for the last 10 years, external schema construction for application-specific database usage has increased its independency from the conceptual schema, as the definitions and implementations of views and procedur...

this article studies the generative grammar approach and some other theories driven from it to lexicon and lexical entries. generative grammar is known as a syntax-based theory, so some aspects of language which have been studied in this theory may have been ignored in other theories. this article shows that more attention has been given to lexicon and lexical entries since 50s. we may claim th...

The growing number of statistical topic models led to the need to better evaluate their output. Traditional evaluation means estimate the model’s fitness to unseen data. It has recently been proven than the output of human judgment can greatly differ from these measures. Thus the need for methods that better emulate human judgment is stringent. In this paper we present a system that computes th...

The retrieval of entity data has always been a core application of database systems and querying an entity's attributes can be efficiently done using declarative languages like SQL. But today's retrieval tasks more and more focus also on conceptual aspects of entities, which often are not directly expressed by attributes. For instance, users might want to find a 'thrilling' novel, unfortunately...

Prior work suggests that patients with mild Alzheimer's disease (AD) often base their recognition memory decisions on familiarity. It has been argued that conceptual fluency may play an important role in the feeling of familiarity. In the present study we measured the effect of conceptual fluency manipulations on recognition judgments of patients with mild AD and older adult controls. "Easy" an...
