Pattern by Example: Type-driven Visual Programming of XML Queries
"... We present Pattern-by-Example (PBE), a graphical language that allows users with little or no knowledge of pattern-matching and functional programming to define complex and optimized queries on XML documents. We demonstrate the key features of PBE by commenting an interactive session and then we pre ..."

Graph Query by Example
"... Abstract. Model-driven tools use model queries for many purposes, including validation of well-formedness rules, specication of derived features, and directing rule-based model transformation. Query languages such as graph patterns may facilitate capturing complex structural relationships between m ..."

Multimodal Pattern Matching for Audio-Visual Query and Retrieval
"... A necessary capability for content-based retrieval is to support the paradigm of query by example. In the past, there have been several attempts to use low-level features for video retrieval. None of the approaches however uses the multimedia information content of the video. We present an algorithm ..."

Coupling the use of audio with video this algorithm can be applied to grouping of shots based on audio-visual similarity. This is much more effective
See What You Want to See: Motivational Influences on Visual Perception,”
- Journal of Personality and Social Psychology,
, 2006
"... People's motivational states-their wishes and preferences-influence their processing of visual stimuli. In 5 studies, participants shown an ambiguous figure (e.g., one that could be seen either as the letter B or the number 13) tended to report seeing the interpretation that assigned them to o ..."

oriented motivational states shows that they influence the perception of visual stimuli. For example, But would a drive toward wishful thinking similarly influence perception? In a sense, this question is a revisiting and a reopening of one of the focal issues of the New Look approach to perception
Query Evaluation with Constant Delay
"... I am grateful to Luc Segoufin who kindly accepted me to be his PhD student. He introduced me to the problem of query enumeration and encouraged me to look for the answers to all the questions that emerged during our collaboration. He was a truly great advisor, always supportive and available for dis ..."

Author manuscript, published in "ICDT (2012) 46-60" Highly Expressive Query Languages for Unordered Data Trees ∗
, 2012
"... We study highly expressive query languages for unordered data trees, using as formal vehicles Active XML and extensions of languages in the while family. All languages may be seen as adding some form of control on top of a set of basic pattern queries. The results highlight the impact and interplay ..."

Visually Specifying Context
, 1999
"... We introduce a simple and novel visual technique for the specification of context in structured documents called T-graphs that we base on T-configurations in document trees. The technique is implemented in the current version of Designer. Although we are applying this technique in the specification ..."

We compare T-graphs with the context specification techniques found in other style
