In this paper, a sample set of 510 simple searches from the TEL action log 2009 is analyzed for query content and query language. More than half of the queries are for named entities, which has consequences for query language disambiguation. A manual identification of query language finds that often a definite language cannot be determined, because many named entities are not translated. Proble...

Since most multimedia database systems are built on top of object or object-relational database systems, they inherit the underlying query facilities. The approach we present in this paper is in two steps. The rst step is to design a multimedia query language that will be used as an internal language. The second step is to deene an equivalent visual query language and a translator to translate ...

We propose a mixed language query disambiguation approach by using co-occurrence information from monolingual data only. A mixed language query consists of words in a primary language and a secondary language. Our method translates the query into monolingual queries in either language. Two novel features for disambiguation, namely contextual word voting and 1-best contextual word, are introduce...

Collaboration in modeling is essential to success, but ORM diagrams intimidate many business people, and most would never install an ORM modeling tool on their computers. The Constellation Query Language (CQL) offers an alternative able to represent almost any ORM2 model in plain text using natural language, with the goal of supporting involvement by all parties through familiar tools including...

We have defined in [RKB99] a database model based on graphs and that puts the emphasis on relationships. This model was designed to support the Prometheus taxonomic model [PK99] and provide taxonomists with means of manipulating taxonomic data naturally and effectively. Since taxonomists are not computing specialists, the choice of graphs also has the advantage of being naturally represented gr...

The query language OVAL which is intended for the integration with the database programming language based on C++ is proposed in this paper. The work addresses the impedance mismatch problem 1] between the syntax and the semantics of the programming and query language. The query language OVAL is based on the functional query language FQL 3] extending it for the manipulation of complex objects. ...

INTRODUCTION With the explosion of data volume and the variety of data sources (Cohen et al., 2009) – two aspects of the big data problem-we observe quite significant difficulties in applying conventional data analysis methodologies to real world problems. The existing technologies for data management and analytics were pushed to the limits of their ability to solve more and more complex analys...

In the prequel paper we introduced the Uni ed State Model (USM), i.e. a single model that allowed conveying objects of popular programming languages and databases. That model exploited and emphasized common properties of all these objects. We showed mappings between those popular data models and USM. Our natural next research goal is the Uni ed Query Language (UQL). UQL is intended to be a mini...

For the scale of data in process keep increasing, data provenance also becomes large and constantly growing, which brings challenges to the efficiency of provenance tracking in process analysis. This paper proposes a kind of dependency view to extract a global data provenance description of the data process instance, and then defines a contextual query language based on dependency view to imple...

Novel concepts are presented to enhance query languages to represent time and uncertainty. We speciically enhance FQL , a deductive and object-oriented query language, with the abilities to adequately represent time and uncertainty .
