This paper tells the story of OQL the standard query language of the Object Database Management Group ODMG The story starts in at INRIA in the Alta r Groupy The objective of that group was to develop an object oriented database system This objective was reached in September the O database system started its commercial career as the main product of a company called O Technology As opposed to its...
متن کاملQunits: queried units for database search
Keyword search against structured databases has become a popular topic of investigation, since many users find structured queries too hard to express, and enjoy the freedom of a “Google-like” query box into which search terms can be entered. Attempts to address this problem face a fundamental dilemma. Database querying is based on the logic of predicate evaluation, with a precisely defined answ...
متن کاملCONQUER: Confusion Queried Online Bandit Learning
We present a new recommendation setting for picking out two items from a given set to be highlighted to a user, based on contextual input. These two items are presented to a user who chooses one of them, possibly stochastically, with a bias that favors the item with the higher value. We propose a second-order algorithm framework that members of it use uses relative upper-confidence bounds to tr...

متن کاملZMDS: Visualizing Structural Entropy in Queried Network Sub-Graphs
The large magnitudes of information in many scale free network datasets makes them difficult to analyze, plot, and visualize. Sacrifices often must be made on the plot’s representational veracity or representational completeness. This paper discusses a method for exploring query based sub-graphs of a larger network using a method based on multidimensional scaling. Since the basis for the networ...
