A system and method for ranking images are provided. The method includes receiving a query comprising a semantic part and an abstract part, retrieving a set of images responsive to the semantic part of the query, and computing first scores for the retrieved images in the set of retrieved images. The first score of an image can be based on a relevance of that image to the semantic part of the query (and not to the abstract part of the query). The method further includes identifying a chromatic concept model from a set of chromatic concept models. This identification can be based on the abstract part of the query (and not on the semantic part of the query). The chromatic concept model includes an optionally-weighted set of colors expressed in a perceptually uniform color space. For retrieved images in the set of retrieved images, the method includes computing a chromatic image model based on colors of the image, the chromatic image model comprising a weighted set of colors expressed in the perceptually uniform color space and computing a comparison measure between the chromatic image model and the chromatic concept model. The retrieved images are scored with respective second scores that are based on the computed comparison measures. The retrieved images are ranked based on a combined score for a respective retrieved image which is a function of the first and second scores.

The present invention relates to processing of textual information in order to automatically answer user-submitted questions pertaining to a given knowledge domain. A proposed system (500) includes a user input interface (510) adapted to receive a user-formulated question (QU) on a natural language format. A transforming module (520), on one hand, converts the user formulated question (QU) into a question template format (QUT) including at least one entity term indicative of a respective main concept embodied in the user formulated question (QU), and on the other hand, converts the user formulated question (QU) into a data instance matching format (QUD) adapted to query a structured database (570), which represents at least a part of a conceptual model of the knowledge domain. A lexicon database (540) contains a multitude of concepts (C) which each is related to a specific question template. A template-matching engine (550) matches the question-template formatted user question (QUT) against the lexicon database (540) to retrieve a matching template cluster (CTQ<m>) associated with a matching query template (TY<m>) and a matching answer template (alphaT<m>), and including at least one matching question template. This template, in turn, has at least one entity slot which is linked to the structured database (570). A data instance-matching engine (560) matches the data-instance-matching formatted user question (QUD) against the structured database (570) to identify at least one matching data instance (Di). A central processing unit (530) fills at least one particular entity slot of the at least one matching question template with the identified at least one matching data instance (Di). A search engine (580) queries the structured database (570) with the matching query template (TY<m>) to retrieve information ([i]) to complete the matching answer template (alphaT<m>). A presentation interface (590) presents an answer (alpha) based on the retrieved information ([i]) and the matching answer template (alphaT<m>).

Methods, systems, and articles of manufacture for context insensitive model entity searching are provided. A model entity is used to identify to a central entity or concept modeled by a database abstraction model. Instances of a model entity may be defined in reference to an identifier in an underlying database. Model entity relationships specify relationships between the model entity and other datasets in the database (e.g., tables of a relational database). A database abstraction model provides an interface to both the model entity and the data in the underlying database. Rather than creating a query of the database using a series of restrictive conditions, or selecting individual the tables or datasets to search, a user may specify search term(s). Instances of the model entity containing the search term(s), regardless of where the search term(s) occur in the underlying database, are returned for the search. Thereafter, a user may select individual instances of the model entity to view in greater detail.

A technique for updating collection-valued and other complex structured columns in a nested table using a nested extension of an UPDATE statement that uses syntax and semantics to modify collection-valued columns in a way that is analogous to the syntax and semantics of the UPDATE statement that is used to modify scalar-valued columns of the table (called the outer UPDATE). Using the same syntactic and semantic constructs as the table at the outer level allows an existing implementation that processes modifications to relational tables to reuse its implementation techniques for processing outer updates to modify collection-valued columns as well. The UPDATE extensions enable the specification of updates to nested collections embedded at arbitrary levels of depth in the object model. The new syntax is embedded inside the outer UPDATE statement in a way that parallels the structure of the data itself and thus maps more directly to the user's conceptual model of the data. The method for implementing the UPDATE extensions uses a change descriptor, which is a data structure that aggregates substantially all changes, both scalar and collection-valued into a single value that can be applied to the changed collection-valued column. This technique can also be used for modifications to other kinds of complex-structured columns such as objects or xml. The change descriptor includes hierarchical information for the cell, thereby enabling efficient application of multiple updates at various granularity levels in a single operation and enabling the implementation of efficient index maintenance algorithms by updating only the indexes affected by the UPDATE operation and updating only those index rows that were affected by the UPDATE operation.
