several semantic image search schemes have been recently proposed to retrieve images from the web. however, the query context is regularly ignored in these techniques and hence, many of the returned images are not adequately relevant. in this paper, we make use of context to further confine the outcome of the semantic search engines. for this purpose, we propose a hybrid search engine which uti...

In this research we investigate the effect of search engine brand on the evaluation of searching performance. Our research is motivated by the large amount of search traffic directed to a handful of Web search engines, even though many have similar interfaces and performance. We conducted a laboratory experiment with 32 participants using a 42 factorial design confounded in four blocks tomeasur...

When emerging technologies such as Search Engine Marketing (SEM) face tasks that require human level intelligence, it is inevitable to use the knowledge repositories to endow the machine with the breadth of knowledge available to humans. Keyword suggestion for search engine advertising is an important problem for sponsored search and SEM that requires a goldmine repository of knowledge. A recen...

Currently, search engines suffer from conceptual problems despite the application of refi ned techniques. The fundamental problem lies in the absence of classical information processing concepts in search engine processing. The limitation of search engines in phrase processing is highlighted in this paper. The results of search engine retrievals are compared with propriety database search resul...

In this paper we describe a language-driven approach to the development of videogames. In our approach the development process starts with the design of a suitable domain-specific language for building games, along with an abstract syntax for the language and its operational semantics. Next an engine supporting the language is built. Finally games are built using the customized language and the...

Web crawlers have been used for nearly a decade as a search engine component to create and update large collections of documents. Typically the crawler and the rest of the search engine are not closely integrated. If the purpose of a search engine is to have as large a collection as possible to serve the general Web community, a close integration may not be necessary. However, if the search eng...

In this paper we describe an FPGA-based platform for high-performance and low-power simulation of neural microcircuits composed from integrate-and-fire (IAF) neurons. Based on high-level synthesis, our platform uses design templates to map hierarchies of neuron model to logic fabrics. This approach bypasses high design complexity and enables easy optimization and design space exploration. We de...
