It is difficult to represent video scenes using keywords. Therefore, in video retrieval, it is not easy to design keyword queries that enable a viewer to represent and find the desired scenes. In this paper, we proposed a video retrieval system that uses handwriting sketches as queries. The user queries the system by drawing a handwriting sketch that includes object shape and motion. The propos...

Graphic sketch representations are effective for representing sketches. Existing methods take the patches cropped from sketches as graph nodes, and construct edges based on sketch's drawing order or Euclidean distances canvas. However, of a may not be unique, while semantically related parts far away each other In this paper, we propose an order-invariant, semantics-aware method graphic represe...

Sketch recognition is the automated understanding of hand-drawn diagrams. Despite the prevalence of keyboards and mice, hand-drawings still pervade in education, design, and other diagrams. This full day tutorial explains why sketch recognition is important, the underlying algorithms, how sketch recognition can be used in traditional interfaces, and the field’s experiences with sketch recogniti...

The Manatee corpus management system on which the Sketch Engine is built is efficient, but unable to harness the power of today’s multiprocessor machines. We describe a new, compatible implementation of Manatee which we develop in the Go language and report on the performance gains that we obtained.

Inputting written Chinese, unlike written English, is a non-trivial operation using a standard keyboard. To accommodate this operation, numerous existing phonetic systems using the Roman alphabet were adopted as a means of input while still making use of a Western keyboard. With the growing prevalence of computing devices capable of pen-based input, naturally sketching written Chinese using a p...

For many languages there are no large, general-language corpora available. Until the web, all but the richest institutions could do little but shake their heads in dismay as corpus-building was long, slow and expensive. But with the advent of the Web it can be highly automated and thereby fast and inexpensive. We have developed a `corpus factory' where we build large corpora. In this paper we d...

Word sketches are one-page automatic, corpus-based summaries of a word’s grammatical and collocational behaviour. These are widely used for studying a language and in lexicography. Sketch Engine is a leading corpus tool which takes as input a corpus and generates word sketches for the words of that language. It also generates a thesaurus and ‘sketch differences’, which specify similarities and ...

Editing a sketch should be one of the essential features provided by sketch recognition systems to allow people to modify what they have drawn, without having to delete and redraw shapes. This paper introduces a control point based editing approach we call RingEdit. RingEdit differs from other sketch editors in that the user actually draws their own control points on the sketch, rather than rel...
